Technical Field

The invention relates to the technical field of circuit breakers, in particular to a circuit breaker protection method, a circuit breaker protection device, a circuit breaker and a storage medium.

Background

A circuit breaker is a common switching device, and is widely used in various fields. Specifically, the circuit breaker is arranged in a certain application scene, and when the current or the voltage in the application scene is overlarge, the circuit breaker can be opened, so that the protection of the circuit breaker is realized.

At present, the opening of the circuit breaker is usually based on a preset threshold, if the threshold is exceeded, the circuit breaker is opened, and if the threshold is not exceeded, the circuit breaker is not opened, so that the circuit breaker is too rigid and is not beneficial to protection of the circuit breaker. For example, the threshold of the circuit breaker is 60 amperes, and when the current exceeds 60 amperes, the circuit breaker is opened; when the current is less than 60 amperes, the circuit breaker operates normally. Such a manner may be suitable for a certain high-current application scenario, but for a low-current application scenario, for example, an application scenario with a current of 8 amperes, even if the current exceeds 8 amperes and reaches 20 amperes or even reaches 50 amperes, the circuit breaker still cannot perform a protection action, and therefore, such a manner makes the circuit breaker unable to perform a good protection function in a low-current application scenario.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In an embodiment, a breaker protection method is provided, and an execution subject of the breaker protection method according to the embodiment of the present invention is a device capable of implementing the breaker protection method according to the embodiment of the present invention, where the device may include, but is not limited to, a breaker.

As shown in fig. 1, a method for protecting a circuit breaker according to an embodiment of the present invention specifically includes:

and 102, acquiring a current parameter value corresponding to a target detection parameter in the circuit breaker.

The detection parameters are parameters which can be detected in the circuit breaker, and the circuit breaker determines whether to execute the protection action by judging parameter values of the parameters. Detecting parameters, which may include but are not limited to voltage parameters, current parameters, and temperature parameters, wherein the voltage parameters include open-phase parameters; the current parameter includes a leakage current parameter.

The target detection parameter is a detection parameter at the current time, that is, a parameter value of the detection parameter at the current time needs to be judged to determine whether an abnormality occurs, and a protection action is triggered when the abnormality occurs.

The current parameter value is a parameter value of the target detection parameter at the current time, for example, the target detection parameter is a voltage parameter, and the parameter value of the voltage parameter at the current time is 200V, so the current parameter value is 200V.

And 104, acquiring a parameter protection interval corresponding to the current parameter value and a current application scene corresponding to the target detection parameter.

And the parameter protection interval is a protection interval which is set in advance according to the breaker information. Illustratively, the breaker information includes a rated voltage and a rated current. The purpose of setting the parameter protection interval is to achieve circuit breaker protection, for example, to trigger circuit breaker protection when the parameter value is not within the parameter protection interval.

Certain detection parameters in the circuit breaker can generate an over-phenomenon when the parameter values are larger and generate an under-phenomenon when the parameter values are smaller, for example, voltage parameters, when the parameter values corresponding to the voltage parameters are larger, an over-voltage phenomenon can occur, and when the parameter values corresponding to the voltage parameters are smaller, an under-voltage phenomenon can occur; for example, when the current parameter value is larger, the overcurrent phenomenon occurs, and when the current parameter value is smaller, the undercurrent phenomenon occurs. Due to the fact that the parameter values corresponding to undervoltage, overvoltage, undercurrent or overcurrent are different, in order to obtain an accurate judgment result and execute corresponding protection actions, a parameter protection interval corresponding to the current parameter value needs to be obtained, and judgment errors are avoided. Therefore, obtaining the parameter protection interval corresponding to the current parameter value includes: and acquiring a parameter protection interval corresponding to the current parameter value according to the size of the current parameter value.

For example, the obtaining of the parameter protection interval corresponding to the current parameter value according to the size of the current parameter value includes: acquiring an under-protection interval and an over-protection interval corresponding to target detection parameters; if the current parameter value corresponding to the target detection parameter is smaller than the maximum value in the under-protection interval, taking the under-protection interval as a parameter protection interval corresponding to the current parameter value; and if the current parameter value corresponding to the target detection parameter is larger than the minimum value in the over-protection interval, taking the over-protection interval as the parameter protection interval corresponding to the current parameter value.

For example, the target detection parameter is a voltage parameter, the under-protection interval corresponding to the voltage parameter is [154V, 209V ], the over-protection interval corresponding to the voltage parameter is [242V, 264V ], if the current parameter value corresponding to the voltage parameter is 170V, the parameter protection interval corresponding to the current parameter value is determined to be [154V, 209V ], that is, whether the current parameter is in an under-voltage state needs to be detected, and if the current parameter is in the under-voltage state all the time, the switching-off is needed; and if the current parameter value corresponding to the voltage parameter is 250V, determining that the parameter protection interval corresponding to the current parameter value is [242V, 264V ], namely whether the current parameter value is in an overvoltage state needs to be detected, and if the current parameter value is always in the overvoltage state, switching off is needed.

The current application scenario is an application scenario of the circuit breaker at the current time, for example, the current application scenario is a high-power oven scenario; as another example, the current application scenario is a low power oven application scenario.

And 106, generating a target protection interval corresponding to the current parameter value according to the parameter protection interval and the current application scene.

And the target protection interval is a protection interval suitable for the current application scene, and whether the current parameter value is abnormal in the current application scene is judged according to the target protection interval so as to execute a protection action when the current parameter value is abnormal in the current application scene.

For example, the parameter protection interval is [230V, 260V ], the current application scenario is a low-power oven application scenario, and since the application scenario is a low-power oven application scenario, the voltage under the application scenario is relatively small, and if the current parameter value is still judged to be abnormal by using the parameter protection interval as [230V, 260V ], the current parameter value is unreasonable, so that the parameter protection interval can be properly reduced, for example, adjusted to [150V, 180V ], and the [150V, 180V ] is used as a target protection interval of the current parameter value, so that the target protection interval is adapted to the application scenario.

And 108, determining whether to execute a protection action according to the current parameter value and the target protection interval.

Illustratively, if the current parameter value is within the target protection interval, no protection action is performed; and if the current parameter value is larger than the maximum value in the target protection interval, executing a protection action.

The circuit breaker protection method comprises the steps of firstly, obtaining a current parameter value corresponding to a target detection parameter in a circuit breaker; then acquiring a parameter protection interval corresponding to the current parameter value and a current application scene corresponding to the target detection parameter; generating a target protection interval corresponding to the current parameter value according to the parameter protection interval and the current application scene; and finally, determining whether to execute a protection action according to the current parameter value and the target protection interval. It can be seen that, since the parameter protection interval and the current application scene generate the target protection interval, the target protection interval can be adapted to the current application scene, and since the target protection interval can be adapted to the current application scene, the circuit breaker can play a good protection role in different application scenes.

In one embodiment, the protection action is not triggered immediately after an abnormality is detected, and may be a detection error, or a parameter value jump phenomenon may occur due to a system burst abnormality. As shown in fig. 2, the determining, according to the current parameter value and the target protection interval, whether to perform a protection action in step 108 includes:

and 108A, acquiring the abnormal time length corresponding to the target protection interval according to the target protection interval.

Wherein, the abnormal time length is a preset time length. It can be understood that, the damage of some detection parameters is relatively large, and if an abnormality is detected in a short time, a protection action must be triggered immediately, for example, a leakage current parameter, and if a current parameter value corresponding to the leakage current parameter is continuously greater than a maximum value in a target protection interval in a short time (for example, 50 milliseconds), the protection action needs to be triggered immediately; and the damage of some detection parameters is relatively small, so that the detection time can be properly prolonged, the protection action is triggered only when the abnormality is continuously detected within relatively long detection time, for example, the temperature parameter, and the protection action is triggered if the current parameter value corresponding to the temperature parameter is continuously greater than the maximum value in the target protection interval within relatively long time (for example, 30 seconds). For the above reasons, it is necessary to determine the abnormal time length corresponding to the target protection interval to generate an abnormal time interval, and then determine whether the abnormality continues to occur according to a plurality of parameter values obtained in the abnormal time interval.

And step 108B, acquiring the detection time of the current parameter value.

The time for detecting the current parameter value is the time for detecting the current parameter value, for example, the time for detecting the current parameter value is: 10:30:01, and then the detection time for determining the current parameter value is 10:30: 01.

And 108C, generating an abnormal time interval according to the detection time of the current parameter value and the abnormal time length.

The abnormal time interval is an interval for determining whether the abnormality continues to occur, for example, if the parameter values detected in the abnormal time interval are all greater than the maximum value in the target protection interval, it is determined that the abnormality continues to occur in a short time, and a protection action needs to be executed.

An example of generation of an abnormal time interval is provided. For example, if the abnormal time length is 3 seconds, and the detection time of the current parameter value is 10:30:01, the abnormal time interval is [10:30:01, 10:30:03 ].

And 108D, obtaining a parameter value set corresponding to the target detection parameter according to the abnormal time interval, wherein the detection time of each parameter value in the parameter value set is within the abnormal time interval.

The parameter value set comprises a plurality of parameter values, the purpose of obtaining the parameter value set is to judge whether continuous abnormity occurs according to the plurality of parameter values in the parameter value set, and if the continuous abnormity occurs, protection action is executed. Specifically, a plurality of parameter values detected in an abnormal time interval are combined to obtain a parameter value set.

And 108E, determining whether to execute a protection action according to the parameter value set and the target protection interval.

Comparing each parameter value in the parameter value set with the target protection interval to obtain a comparison result of each parameter value; and determining whether to execute the protection action according to the comparison result of each parameter value. For example, if each parameter value in the set of parameter values is greater than the maximum value in the target protection interval, a protection action is performed, e.g., a brake-separating action is performed.

In one embodiment, the types of the target guard interval include an over-interval type and an under-interval type.

The over-interval type indicates that each value in the target protection interval is relatively large and exceeds a rated value. For example, the rated voltage is 220V, when the type of the target protection interval is an over-interval type, the target protection interval may be 230V, 260V.

And the under-interval type indicates that all values in the target protection interval are relatively small and are smaller than the rated value. For example, the rated voltage is 220V, the target guard interval may be 170V, 210V when the type of the target guard interval is the under interval type.

As shown in fig. 3, the determining whether to perform a protection action according to the parameter value set and the target protection interval in step 108E includes:

step 108E1, if the type of the target protection interval is an over-interval type, counting the number of parameter values in the parameter value set that are greater than the maximum value in the target protection interval; if the number of the parameter values in the parameter value set, which are larger than the maximum value in the target protection interval, is larger than a first preset number, executing a protection action; otherwise, updating the abnormal excessive times corresponding to the target detection parameters to generate overhaul prompt information according to the abnormal excessive times.

For example, if the target guard interval is [230V, 260V ], the maximum value in the target guard interval is 260V, and the minimum value in the target guard interval is 230V.

The first preset number is a preset number, and the first preset number is used for judging whether the phenomenon continuously appears or not.

Wherein, the abnormal excessive times refers to the times of the excessive phenomenon of the target detection parameters. Two updating methods of abnormal times are provided. Adding the number of parameter values in the parameter value set, which are greater than the maximum value in the target protection interval, to the historical abnormal excess times to update the abnormal excess times corresponding to the target detection parameter, for example, if the first preset number is 20, the number of parameter values in the parameter value set, which are greater than the maximum value in the target protection interval, is 5, and is less than the first preset number, acquiring the historical abnormal excess times corresponding to the target detection parameter, and if the historical abnormal excess times is 40, adding the historical abnormal excess times to the number of parameter values in the parameter value set, which are greater than the maximum value in the target protection interval, to obtain an updated abnormal excess times of 45; and secondly, determining multiple times of abnormities in a short time as one-time abnormities, then adding 1 to the historical abnormal excessive times to update the abnormal excessive times corresponding to the target detection parameters, continuing the above example, if the number of parameter values in the parameter value set, which are larger than the maximum value in the target protection interval, is 5, then treating the 5 times of abnormities as one-time abnormities, and adding 1 to the historical abnormal excessive times to obtain an updated abnormal excessive times of 41. It can be understood that if the target detection parameter is over-occurred continuously within a period of time, in order to guarantee the power utilization safety, the over-maintenance prompt message needs to be generated to prompt the maintenance personnel.

The over-overhaul prompt message is used for prompting the overhaul personnel to overhaul the phenomenon. For example, the overhaul prompt message is "the number of abnormal overhauls has reached N times, please schedule overhaul immediately".

In the embodiment of the present invention, when the number of parameter values in the parameter value set that are greater than the maximum value in the target protection interval is greater than a first preset number, it is considered that an over phenomenon continues to occur, and in order to ensure power consumption safety, a protection action needs to be immediately performed.

Step 108E2, if the type of the target protection interval is an under-interval type, counting the number of parameter values in the parameter value set that are smaller than the minimum value in the target protection interval; if the number of the parameter values in the parameter value set, which are smaller than the minimum value in the target protection interval, is larger than a second preset number, executing a protection action; otherwise, updating the abnormal lack times corresponding to the target detection parameters to generate lack maintenance prompt information according to the abnormal lack times.

The second preset number is a preset number, and the second preset number is used for judging whether the under phenomenon continuously appears.

Wherein, the abnormal defaulting times refer to the times of defaulting of the target detection parameters. The update method of the abnormal under number is the same as the update method of the abnormal over number, and is not described in detail here.

The under-overhaul prompting information is information for prompting the maintainers to carry out under-overhaul. For example, the under-inspection prompt message is "the abnormal under-inspection number has reached N times, please schedule the inspection immediately".

In the embodiment of the invention, when the number of the parameter values in the parameter value set, which are smaller than the minimum value in the target protection interval, is greater than the second preset number, it is considered that the underphenomenon continuously occurs, and in order to ensure the electricity safety, a protection action needs to be immediately executed.

In an embodiment, as shown in fig. 4, the step 106 of generating a target protection interval corresponding to the current parameter value according to the parameter protection interval and the current application scenario includes:

and 106A, acquiring a scene power utilization interval corresponding to the current application scene.

The scene power utilization interval refers to a power utilization interval in a current application scene, for example, the power utilization interval in the current application scene is 2 amperes to 8 amperes, and the scene power utilization interval corresponding to the current application scene is 2 amperes to 8 amperes.

And 106B, generating a target protection interval corresponding to the current parameter value according to the parameter protection interval and the scene power utilization interval corresponding to the current application scene.

In one embodiment, in order to ensure that the target protection interval is adapted to the application scene and at the same time ensure that the generated target protection interval is within the range that can be protected by the parameter protection interval, the target protection interval needs to be determined according to the maximum value and the minimum value in the scene power utilization interval and the maximum value and the minimum value in the parameter protection interval. As shown in fig. 5, the step 106B of generating the target protection interval corresponding to the current parameter value according to the parameter protection interval and the scene power consumption interval corresponding to the current application scene includes:

step 106B1, if the scene power consumption interval corresponding to the current application scene is within the parameter protection interval, generating a target protection interval corresponding to the current parameter value according to the scene power consumption interval corresponding to the current application scene.

Obtaining interval increment and interval decrement; determining the maximum value in the target protection interval according to the interval increment and the maximum value in the scene electricity utilization interval; determining the minimum value in the target protection interval according to the interval decrement and the minimum value in the scene electricity utilization interval; and obtaining the target protection interval according to the maximum value and the minimum value in the target protection interval. For example, the parameter protection interval is [30V, 60V ], the scene power consumption interval is [40V, 50V ], the interval increment is 5V, and the interval decrement is 5V, so that the target protection interval is determined to be [35V, 55V ], and if the interval increment and the interval decrement are both 0V, the target protection interval is determined to be [40V, 50V ].

Step 106B2, if the maximum value in the scene power consumption interval corresponding to the current application scene is within the parameter protection interval and the minimum value in the scene power consumption interval corresponding to the current application scene is smaller than the minimum value in the parameter protection interval, generating a target protection interval corresponding to the current parameter value according to the minimum value in the parameter protection interval and the maximum value in the scene power consumption interval corresponding to the current application scene.

For example, if the parameter protection interval is [30V, 60V ], the scene power consumption interval is [25V, 50V ], and the generated target protection interval is [30V, 50V ], or [30V, 55V ], or [35V, 55V ].

Step 106B3, if the minimum value in the scene power consumption interval corresponding to the current application scene is within the parameter protection interval and the maximum value in the scene power consumption interval corresponding to the current application scene is greater than the maximum value in the parameter protection interval, generating a target protection interval corresponding to the current parameter value according to the maximum value in the parameter protection interval and the minimum value in the scene power consumption interval corresponding to the current application scene.

For example, if the parameter protection interval is [30V, 60V ], the scene power consumption interval is [40V, 70V ], and the generated target protection interval is [40V, 60V ], or [40V, 55V ], or [45V, 55V ].

In one embodiment, not only actual application scenes but also user personalized settings are considered, so that the electricity safety is guaranteed, and the user experience is improved. As shown in fig. 6, the step 106B of generating the target protection interval corresponding to the current parameter value according to the parameter protection interval and the scene power consumption interval corresponding to the current application scene includes:

and step 106Ba, obtaining a user-defined electricity utilization interval corresponding to the current application scene.

The power utilization interval is defined by a user corresponding to the current application scene, and is set by the user aiming at the current application scene. As shown in fig. 7, a user can set user-defined power consumption intervals corresponding to different application scenes through a user interface, a user terminal sends the user-defined power consumption intervals corresponding to the different application scenes set by the user to a server, and the server sends the user-defined power consumption intervals corresponding to the different application scenes set by the user to a circuit breaker, so that the circuit breaker obtains the user-defined power consumption intervals corresponding to the different application scenes.

And 106Bb, generating a target protection interval corresponding to the current parameter value according to the parameter protection interval, the scene power utilization interval corresponding to the current application scene and the user-defined power utilization interval.

For example, if the parameter protection interval is [30V, 60V ], the scene power consumption interval is [40V, 70V ], and the user-defined power consumption interval corresponding to the current application scene is [40V, 60V ], the target protection interval is [40V, 60V ]; if the user-defined electricity utilization interval corresponding to the current application scene is 35V, 60V, the target protection interval is 40V, 60V; and if the user-defined electricity utilization interval corresponding to the current application scene is [35V, 75V ], determining that the target protection interval is [40V, 60V ].

In one embodiment, the user is reminded when the current parameter value is not particularly large so that the user knows that an abnormality is likely to occur, and the brake is directly switched off when the current parameter value is particularly large, so that direct protection is realized. The target protection interval comprises a first protection interval and a second protection interval, the maximum value in the first protection interval is smaller than the minimum value in the second protection interval, and the protection action comprises a reminding action and a brake separating action; as shown in fig. 8, the determining whether to perform a protection action according to the current parameter value and the target protection interval in step 108 includes:

and 108a, if the current parameter value is larger than the maximum value in the first protection interval, executing a reminding action, wherein the reminding action comprises sending reminding information to a server.

For example, the first protection interval is [40V, 60V ], the maximum value in the first protection interval is 60V, and when the current parameter value is greater than 60V, a reminding action is performed, that is, the circuit breaker sends a reminding message to the server, so that the server sends the reminding message sent by the circuit breaker to the user terminal, and the user knows that an abnormality is likely to occur.

And step 108b, if the current parameter value is larger than the maximum value in the second protection interval, executing a brake-off action.

For example, the second protection interval is [70V, 120V ], the maximum value in the second protection interval is 120V, and when the current parameter value is greater than 120V, the opening action is executed, that is, the breaker is opened, so as to realize direct protection.

If the current parameter value is greater than the maximum value in the second protection interval, executing a switching-off action, further comprising: and if the current parameter value is larger than the maximum value in the second protection interval, executing a brake separating action, generating brake separating prompt information, and sending the brake separating prompt information to a server.

Because the circuit breaker still sends the separating brake suggestion information to the server when separating brake, the server can send separating brake suggestion information to user terminal to let the user know the circuit breaker has now separated brake.
