Abstract
The utility model provides a circuit breaker actuating mechanism for a three-phase power supply protector. In the circuit breaker actuating mechanism, a controllable electromagnetic device is used for carrying out switching-on/off actions; when an electric-leakage circuit breaker in an automatic recloser is tripped, an intelligent unit electrifies the controllable electromagnetic device for movement after judging that a circuit is in accordance with a reclosing condition, a transmission gear and a rack of the controllable electromagnetic device are meshed for transmission, and the controllable electromagnetic device drives an operation handle to be pulled back to a switching-off position to move for a certain distance so as to realize the closing of the circuit breaker; after the controllable electromagnetic device continuous moving to result in overlarge torque, the controllable electromagnetic device is reversed automatically, the controllable electromagnetic device drives the operation handle to a switching-on position to realizing switching-on, after the switching-on is performed in place, a sensor in the circuit breaker at a bottom shell performs detection to generate a position signal and notifies the intelligent unit, then the intelligent unit cuts off the power supply of the controllable electromagnetic device, and thus, the switching-on is completed; and when the entire automatic recloser undergoes short circuit, electric leakage, overvoltage and other conditions, the automatic recloser is tripped, so that the entire opening and closing cycle is completed. In addition, the switching-on/off action of the circuit breaker actuating mechanism disclosed by the utility model can also be switched between manual or local control and automatic or remote control.
