Problems solved by technology

[0002] A circuit breaker with leakage protection is generally assembled side by side with a leakage protector and a miniature circuit breaker. A set of tripping components are respectively provided, and the linkage between the two is realized through a linkage mechanism. The input terminal internal wire and the connecting terminal wire of the circuit breaker pass through the input terminal internal connection on the seat shell and the cover shell of the previous circuit breaker respectively. The wire hole and the wire hole at the connection end go through the hole on the housing of the earth leakage protector, and the inner wire at the input end passes through the zero-sequence transformer in the earth leakage protector and joins with the wire at the connection end, that is, the power input of each phase circuit breaker passes through After the circuit breaker disconnects the circuit, it is necessary to detect and observe whether the circuit is leaking, but the existing circuit breaker cannot display the voltage in time, and cannot be remotely controlled, requiring workers to open the motor box and pull back the circuit breaker The switch is restored, and the operation is troublesome

Embodiment 1

[0025] Embodiment 1: An intelligent circuit breaker for leakage protection self-test and self-test, including a circuit breaker outer shell 3 and an anti-return unit 9;

[0026] Circuit breaker housing 3: the battery 1 and the voltmeter 4 are fixed on the upper side, the upper electric shock block 15 is fixed on the inner upper side, the resistor 12 is fixed on the inner lower side, and the spring 10 is fixed on the inner lower side, and the spring 10 has two One, the other end of two springs 10 is fixed with movable plate 17, and the upper side of movable plate 17 is fixed with lower electric shock block 16, and upper electric shock block 15 and lower electric shock block 16 are arranged up and down correspondingly, and the middle end lower side of movable plate 17 A second suction cup 13 is interspersed, and a second electromagnetic coil 14 is fixed on the inner lower side of the circuit breaker housing 3. The second electromagnetic coil 14 and the second suction cup 13 are a...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is:

[0031]In this embodiment, it also includes a limiting rod 11, which has two and the lower ends are fixed on the inner lower side of the circuit breaker outer casing 3, and the upper end moves through the moving plate 17, which is located in the second spring 10, and through the limiting The rod 11 prevents the moving plate 17 from moving left and right, and also includes a fixing seat 7, the front side is fixed on the rear side of the circuit breaker housing 3, and its four corners are threaded through screws, and the device is conveniently fixed to the external equipment through the fixing seat 7 There are two external connecting pipes 2, which are arranged symmetrically. The right ends of the two external connecting pipes 2 pass through the left side of the circuit breaker outer casing 3. By connecting the lower electric shock block 16 and the second electromagnetic coil 14 The electric wire passes through ...

Embodiment 3

[0033] The difference between this embodiment and embodiment two is:

[0034] In this embodiment, a wireless transceiver 5 is also included, which is fixed on the upper side of the circuit breaker outer shell 3, and its input terminal is electrically connected to the output terminal of the single-chip microcomputer 6, and the external remote device can control the device through the wireless transceiver 5. Also comprise loudspeaker 8, be fixed on the right side of circuit breaker outer casing 3, its input end is electrically connected the output end of single-chip microcomputer 6, can remind worker's circuit disconnected by loudspeaker 8.

[0035] When in use: when the circuit is normal, the second spring 10 stretches, and the moving plate 17 moves up, so that the upper electric shock block 15 and the lower electric shock block 16 are contacted and energized. At this time, the second electromagnetic coil 14 generates a magnetic force, but this magnetic force cannot overcome the...
