Electric leakage self-locking tripping mechanism of circuit breaker

Abstract

The electric leakage self-locking tripping mechanism comprises a connecting seat, a tripper is arranged at the top of the connecting seat, a tripper support is arranged at the top of the tripper, and a lock catch reaction spring is arranged at the top of the tripper support. When the circuit breaker trips due to leakage current of a line outgoing line, the circuit breaker can be locked by an electric leakage self-locking function, so that the circuit breaker is kept in a disconnected state, the circuit breaker cannot be switched on in the local or remote operation, and the circuit breaker can be switched on in the remote or local operation only after the electric leakage fault needs to be checked and removed and then a self-locking key is reset. The device can better protect the electricity utilization safety of people or equipment, and is simple in structure, convenient to produce and safe and reliable in electricity utilization.

Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and specifically to a leakage self-locking tripping mechanism for a circuit breaker. Background Art

[0002] Existing external circuit breakers for electric energy meters only have leakage status indication, generally using lamp flashing or lamp color warning or alarm. There is no self-locking function. The circuit breaker can also be briefly closed to connect the circuit without contacting the leakage fault, which is likely to cause secondary injury to the electric shock personnel. Summary of the Invention

[0003] Aiming at the above-mentioned disadvantages existing in the prior art, the purpose of the present invention is to provide a leakage self-locking tripping mechanism for a circuit breaker.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A leakage self-locking tripping mechanism for a circuit breaker, including a connection seat, a tripping device is provided on the top of the connection seat, a tripping device support is provided on the top of the tripping device, and a locking reaction spring is provided on the top of the tripping device support.

[0005] Preferably, a lock is provided on the top of the locking reaction spring, and a lock rod is provided on the left side of the lock.

[0006] Preferably, a reset button is provided on the left side of the lock rod.

[0007] Preferably, a reaction spring is provided on the top of the reset button.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] The present invention has a leakage self-locking function for an external leakage circuit breaker of an electric energy meter (hereinafter referred to as the circuit breaker). When the circuit breaker trips due to leakage current in the line, the leakage self-locking function will lock the circuit breaker, keeping the circuit breaker in the off state. It is impossible to close the circuit breaker either locally or remotely. It is necessary to first check and eliminate the leakage fault, and then reset the self-locking key before the circuit breaker can be remotely or locally operated to close, which can better protect the electrical safety of people or equipment. The device has a simple structure, is easy to produce, and is safe and reliable in use. Brief Description of the Drawings

[0014] Please refer to Figures 1-3 , the present invention provides a technical solution: a leakage self-locking tripping mechanism of a circuit breaker, the leakage self-locking tripping mechanism of the circuit breaker, including a connecting seat 1, a release 2 is provided on the top of the connecting seat 1, a release support 3 is provided on the top of the release 2, a latching reaction spring 4 is provided on the top of the release support 3, a latch 5 is provided on the top of the latching reaction spring 4, a locking rod 6 is provided on the left side of the latch 5, a reset button 7 is provided on the left side of the locking rod 6, and a reaction spring 8 is provided on the top of the reset button 7.

[0015] Working principle: In the leakage self-locking function of the external leakage circuit breaker of the electric energy meter, (the external leakage circuit breaker of the electric energy meter is hereinafter referred to as the circuit breaker) when a leakage current occurs in the line and the circuit breaker trips, the leakage self-locking function will lock the circuit breaker, keeping the circuit breaker in the open state. It is impossible to close the circuit breaker either locally or remotely. It is necessary to first check and eliminate the leakage fault, and then reset the self-locking key before the circuit breaker can be remotely or locally operated to close. This can better protect the safety of people or equipment using electricity, protect the remote control mechanism (mainly protect the leakage self-locking tripping mechanism), and protect the combination of the leakage self-locking tripping mechanism and the structure of the external circuit breaker of the electric energy meter.
