Background

The circuit breaker is a switching device capable of closing, carrying, and opening/closing a current under a normal circuit condition and a current under an abnormal circuit condition within a prescribed time. When the current is abnormal, the magnetic field generated by the large current overcomes the counterforce spring, the release pulls the operating mechanism to act, and the switch trips instantly. But after tripping, the reset switch can be electrified again after tripping. However, other abnormal hidden dangers such as short circuit of the circuit still exist, and the maintenance personnel do not necessarily know that the circuit breaker trips once in the regular inspection process, so that the potential safety hazard can not be eliminated in time. Therefore, how to enable the inspection personnel to know the operating state of the circuit breaker is particularly important for eliminating the potential safety hazard.

Detailed Description

The following description and the drawings sufficiently illustrate specific embodiments of the invention to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. The examples merely typify possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in or substituted for those of others.

In some illustrative embodiments, as shown in fig. 1-2, a circuit breaker with an alarm function includes a circuit breaker housing 1 and a switch trip 2, the switch trip 2 being mounted on the circuit breaker housing 1; the alarm structure component is also included;

the alarm structure assembly includes: an alarm connecting rod 3, a disposable brittle rod 4, a side connecting rod 5 and a connecting rod frame 6.

The alarm connecting rod 3 is made of PVC, holes are uniformly formed in the surface of the alarm connecting rod, the problem of heat dissipation of the alarm structure assembly is solved through the holes, and the influence of heat dissipation on the circuit breaker can be reduced. Moreover, the sound and light warning can be heard and seen conveniently through the opening. The two side connecting rods 5 are arranged at two ends of the alarm connecting rod, and the installation mode can be various existing connection modes, such as connecting the side connecting rods 5 with the alarm connecting rod 3 through bolt connection or bonding the side connecting rods 5 with the alarm connecting rod 3 through double-faced adhesive.

And then the disposable brittle rod 4 is arranged above the alarm connecting rod 3 in parallel, and the height distance between the disposable brittle rod 4 and the alarm connecting rod 3 is 5mm, so that enough fracture space is provided for the fracture of the disposable brittle rod 4. Both ends of the disposable brittle rod 4 are respectively connected with the two side links 5, so that the disposable brittle rod 4 is fixed in the middle of the two side links 5.

The link frame 6 is assembled and connected with the side link 5, and the existing connection mode is adopted for assembling the link frame 6 and the side link 5, which is not limited specifically herein. Connecting rod frame 6 install in on the circuit breaker casing, for the convenience of the installation of connecting rod frame 6, connecting rod frame 6 is equipped with two-sided adhesive tape 7 with circuit breaker casing 1's junction, through two-sided adhesive tape 7, with connecting rod frame 6 directly glue on circuit breaker casing 1 can, have the equipment convenient, use convenient characteristics.

The disposable brittle rod 4 is positioned on a path from the opening position to the closing position of the switch tripping 2, so that when the switch tripping 2 is tripped due to a short circuit, the switch tripping 2 moves from the opening position to the closing position, the disposable brittle rod 4 can be impacted in the moving process, the disposable brittle rod 4 can be broken after being impacted, the broken part cannot be repaired, and therefore a maintainer can know that the switch tripping 2 is tripped once. After the maintenance, the maintenance personnel take off the broken disposable brittle rod 4 and install the new disposable brittle rod 4 again.

In addition, in order to remind the maintainer, the repairment discovery is easily examined in order to disposable fragile pole 4 after the fracture, be equipped with metal safety line 8 in the disposable fragile pole 4, be equipped with bee calling organ 9 in the warning connecting rod 3, metal safety line 8 with bee calling organ 9 is connected, and connection method has a plurality ofly, and it can to adopt current electric connection mode, if can accomplish the connection through the mode of metal copper sheet touching contact, connection mode for prior art does not give unnecessary details here. If the metal safety wire 8 is broken, the buzzer is electrified to buzz to warn; the warning LED lamp post 10 is electrically connected with the buzzer 9. When the buzzer 9 is electrified to buzz, the warning LED lamp post 10 is also electrified to work at the same time, and the warning LED lamp post can be selected to be red light, so that the warning LED lamp post is easier to observe and discover. Buzzer 9, warning LED lamp pole all should be connected with the power, and the power can be provided the power supply by the battery, and is convenient. The metal safety wire 8, the buzzer 9, the warning LED lamp post and the power supply can be connected according to known circuit knowledge, for example, the metal safety wire is used for short-circuiting the buzzer and the warning LED lamp post, and when the metal safety wire is broken, the buzzer and the warning LED lamp post are electrified to work. Or may be implemented by using other existing circuit structures, which are not described herein.

During the use, take place the tripping operation when the circuit breaker, switch tripping operation 2 is by opening and shutting when position to the shut position, and the disposable fragile pole 4 of 2 striking of switch tripping operation makes disposable fragile pole 4 fracture tears the metal safety line 8 in the disposable fragile pole 4 to thereby buzzer sends buzzing and the LED lamp pole of warning sends light maintainer of warning. Thereby timely staff trips the switch 2 of circuit breaker and pulls the position of opening and shutting, and cracked disposable fragile pole 4 also can't be restoreed, and bee calling organ and warning LED lamp pole also can warn always. Therefore, the maintenance personnel can know that the trip occurs once and inquire or investigate potential safety hazards in time.

In an optional embodiment, the side link 5 is provided with sliding grooves 11 adapted to the two ends of the disposable brittle rod 4, and the two ends of the disposable brittle rod 4 respectively slide into the sliding grooves 11 of the side link 5, so that the disposable brittle rod 4 is more convenient to replace.

The above embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, simplifications and equivalents which do not depart from the spirit and principle of the present invention should be construed as being included in the scope of the present invention.
