When the micro switch is in the closed state, the circuit breaker is in the closed state. When there is leakage in the line and trips, the micro switch is in the open state. At this time, the circuit breaker is in the open state, and the existing circuit breaker can only detect the open circuit The breaker is in the opening (tripping) or clo

The invention provides a residual-current circuit breaker. The residual-current circuit breaker comprises a motor, a movement mechanism and three photoelectric switches, wherein one end of the movement mechanism is connected with the motor; when the motor drives the movement mechanism to move to three different position states, one of the three photoelectric switches is switched off by a shading part in the movement mechanism separately; and the three photoelectric switches are corresponding to three states of the circuit breaker respectively. According to the residual-current circuit breaker, the motor is used to drive the movement mechanism to move to enable the shading part of the movement mechanism to switch off different photoelectric switches in different states of the circuit breaker, so that the purpose of detecting the switch-on, switch-off (tripping) and switch-on (re-tripping) states of the circuit breaker in real time is realized; and in addition, the residual-current circuit breaker is simple in structure, so that the state of the circuit of the circuit breaker can be obtained according to the state of the circuit breaker conveniently.
Description
technical field [0001] The present invention relates to the technical field of circuit breakers, in particular to an earth leakage circuit breaker. Background technique [0002] At present, leakage circuit breakers on the market mainly detect the current state of the switch through micro switches. When the micro switch is in the closed state, the circuit breaker is in the closed state. When there is leakage in the line and trips, the micro switch is in the open state. At this time, the circuit breaker is in the open state, and the existing circuit breaker can only detect the open circuit The breaker is in the opening (tripping) or closing state. In addition, the design cost of detecting the state of the circuit breaker through the micro switch is relatively high. overall performance of the device. Therefore, the main problem of the leakage circuit breaker in the prior art is that it cannot detect the opening (re-buckle) state of the circuit breaker. Contents of the inven...
