Control device of circuit breaker of bistable permanent-magnetism mechanism

The utility model discloses a control device of a circuit breaker of a bistable permanent-magnetism mechanism, which comprises the circuit breaker of the bistable permanent-magnetism mechanism and an operation box. The control device of the circuit breaker of the bistable permanent-magnetism mechanism also comprises a closing relay and a tripping relay. Both ends of a normally closed contact of the circuit breaker of the bistable permanent-magnetism mechanism are respectively connected with the closing control end of the operation box and a control coil of the closing relay; both ends of a normally open contact of the closing relay are respectively connected with the closing control end of the circuit breaker of the bistable permanent-magnetism mechanism; both ends of a normally open contact of the circuit breaker of the bistable permanent-magnetism mechanism are respectively connected with the tripping control end of the operation box and a control coil of the tripping relay; and both ends of a normally open contact of the tripping relay are respectively connected with the tripping control end of the circuit breaker of the bistable permanent-magnetism mechanism. The control device of the circuit breaker of the bistable permanent-magnetism mechanism has the advantages that the circuit breaker of the bistable permanent-magnetism mechanism and an electric loop of the operation box are isolated off, and the impact is large when the circuit breaker of the bistable permanent-magnetism mechanism works; and moreover, the impact resisting capabilities of the relays are strong, the circuit breaker of the bistable permanent-magnetism mechanism is protected, and the operation box is also protected.
