Detailed Description

The principles of embodiments of the present disclosure will now be described with reference to various exemplary embodiments shown in the drawings. It should be understood that these embodiments are described merely to enable those skilled in the art to better understand and further implement the embodiments of the present disclosure, and are not intended to limit the scope of the embodiments of the present disclosure in any way. It should be noted that where feasible, similar or identical reference numerals may be used in the figures and that similar or identical reference numerals may indicate similar or identical functions. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the embodiments of the disclosure described herein.

The structure of the circuit breaker according to the exemplary embodiment of the present disclosure will be described in detail with reference to fig. 1 and 2. Referring first to fig. 1, fig. 1 illustrates a block diagram of a circuit breaker according to an embodiment of the present disclosure.

As shown in fig. 1, the circuit breaker 100 described herein includes a frame 101, a circuit breaker body 102, sensors 103, 104, 105, 106, and a data processing module 107. The frame 101 is used to mount the sensors 103, 104, 105, 106 and the data processing module 107. The breaker main body 102 is used to make and break an electric circuit. The sensors 103, 104, 105, 106 are used to acquire status parameters of the circuit breaker body. The data processing module 107 is configured to process the status parameters collected by the sensors 103, 104, 105, 106 and output the processed status parameters to a device external to the circuit breaker 100 for use by a user.

In certain embodiments, the data processing module 107 may be, for example, a concentrator for acquiring data of sensors (such as sensors 103, 104, 105, 106) mounted on the circuit breaker body 102, processing, storing, and uploading the data. The concentrator converts the sensor data collected by the protocol into a signal form which can be identified by a user and outputs an indication signal when the data meets a certain condition, for example, when the value collected by the temperature sensor is higher than a preset threshold value, the concentrator can output an alarm signal. The data processing module 107 analyzes the health status of the circuit breaker 100 according to the status parameters output by the sensors and displays the remaining electrical life of the circuit breaker 100. In other embodiments, the data processing module 107 may be other data processing elements, which may be determined according to specific design requirements and cost.

In certain embodiments, the data processing module 107 may be connected to the sensor, for example, in a wired manner, for example, by a cable. In other embodiments, in order to meet specific connection requirements, such as isolation between the sensor and the data processing module 107, the data processing module 107 may be connected to the sensor in a wireless manner, such as via Wifi or the like, which may be determined according to specific design requirements and cost.

In certain embodiments, the data processing module 107 can include, for example, a plug adapted to connect the data processing module 107 to a device (e.g., a display) external to the circuit breaker 100 to upload the processed data to the external device for use by a user. For example, the plug includes a serial interface, such as RS-232, RS-485, etc., to accommodate common devices. In other embodiments, the data processing module 107 may include other types of connectors to connect to devices external to the circuit breaker 100, for example, a mobile phone external to the circuit breaker may be connected via Wifi, and the data of each sensor may be viewed through a page on the mobile phone, which may be determined according to specific design requirements and cost.

The sensors 103, 104, 105, 106 are used to monitor various status parameters of the circuit breaker body 102 for use by a user. For example, management of the health state of the circuit breaker is realized through multi-dimensional operation monitoring; the circuit breaker health scoring, operation and maintenance suggestions and plans are provided, so that the operation continuity and reliability can be improved, the maintenance period can be prolonged, and the maintenance cost can be reduced.

In some embodiments, the sensors include a temperature sensor 103 for detecting at least one of a temperature of the circuit breaker body 102, a temperature of a bus bar lap of a switchgear cabinet in which the circuit breaker 100 is located, and a temperature of a cable lap of the switchgear cabinet. The data processing module 107 may output an alarm signal when the temperature value collected by the temperature sensor 103 is higher than a predetermined threshold value.

In certain embodiments, the temperature sensor 103 may be self-powered, for example, without additional wiring, maintenance-free, and use magnetic saturation techniques to ensure safe and stable long-term operation. In some embodiments, the temperature sensor 103 may employ a radio frequency technology, so as to completely electrically isolate the temperature measurement unit on the high voltage side from the low voltage side receiving unit in the temperature sensor 103, thereby ensuring safety. In other embodiments, the temperature sensor 103 may be other types of temperature sensors, as may be determined by specific design requirements and cost.

In some embodiments, the sensors also include a current sensor 106 for detecting the current through the circuit breaker body 102. When the current exceeds the current threshold, the output processing module 107 generates indication information.

In some embodiments, the sensors further include a secondary device state sensor configured to monitor states of secondary devices of the circuit breaker main body, such as currents and action times of a closing coil, an opening coil and an energy storage motor, so as to extract a characteristic waveform from a current curve, identify an early fault of the circuit breaker 100, and guarantee safe operation. When an early failure is identified, the output processing module 107 generates indication information.

In some embodiments, the current sensor 106 is implemented as a hall sensor to be independent of the existing control and protection systems of the circuit breaker 100, thereby not affecting the existing reliability of the circuit breaker 100. In other embodiments, the current sensor 106 may be other types of current sensors as well, which may be determined based on specific design requirements and cost.

In some embodiments, the sensors further include state sensors, such as attitude sensors 104 and transient sensors 105, for monitoring the mechanical state of the circuit breaker body 102, thereby visually quantifying the health of the circuit breaker 100, effectively identifying early failure of mechanical components within the circuit breaker 100, and ensuring proper operation of the circuit breaker 100. The data processing module 107 may output an alarm signal when the data detected by the attitude sensor indicates a change in the machine state, or an early failure of the machine component is identified.

For example, the motion curve of the mechanical mechanism in the circuit breaker 100 is extracted by the attitude sensor to monitor the motion condition of the mechanical mechanism in the circuit breaker in real time, and one or more mechanical characteristic parameters of the circuit breaker 100, such as a stroke, a closing time, a breaking time, an average closing speed, an average breaking speed, a closing overshoot, a breaking bounce and the like, are calculated. More parameters can be obtained by combining the transient sensor, such as overtravel, vacuum arc extinguish chamber opening distance, contact pressure of a contact of the vacuum arc extinguish chamber and the like.

In some embodiments, the attitude sensor 104 may be, for example, an angle sensor for detecting the angle of movement of a mechanical mechanism within the circuit breaker 100. In other embodiments, the attitude sensor 104 may be other types of sensors, which may be determined based on specific design requirements and cost.

In some embodiments, the transient sensor 105 may be, for example, a force sensor for detecting changes in the force of mechanical mechanisms within the circuit breaker 100. In other embodiments, the transient sensor 105 may be other types of sensors, such as a pressure sensor, configured to monitor the contact pressure of the circuit breaker body 102, and the data processing module 107 is configured to generate the indication information in response to changes in the contact pressure, which may be determined according to specific design requirements and cost.

Next, the installation of the data processing module 107 will be explained with reference to fig. 2. Fig. 2 shows an installation schematic of a data processing module in a circuit breaker according to an embodiment of the disclosure. In the embodiment shown in fig. 2, the data processing module 107 and the frame 101 are connected by fasteners.

Specifically, a screw hole 109 is provided on the housing of the data processing module 107. Meanwhile, corresponding through holes 110 are also provided at corresponding positions of the frame 101 where the data processing modules 107 are installed. On the side of the frame 101 opposite to the side on which the data processing module 107 is mounted, screws 108 are mounted into screw holes 109 of the data processing module 107 through holes 110 of the frame 101, so that the data processing module 107 is mounted to the frame 101. Meanwhile, the position where the data processing module 107 is mounted on the frame 101 may be determined according to a specific design.

In other embodiments, the data processing module 107 may be mounted in other ways. For example, a rail (not shown) is provided on a side wall inside the frame 101, and a mounting portion is provided on the rail, which mounting portion can slide on the rail. The data processing module 107 is detachably mounted on the mounting portion. In this way, the position of the data processing module 107 can be adjusted as desired. This may be determined based on specific design requirements and cost.

Through the embodiment of the disclosure, the data processing module is integrated inside the circuit breaker, so that various state parameters of the circuit breaker can be directly output to external equipment for use by a user, and the use by the user is facilitated.
