disjuntor com função de auto-bloqueio de curto-circuito

摘要

The present invention discloses a circuit breaker with a function of self-locking upon short circuit which has a mechanism of self-locking upon short circuit provided in the circuit breaker. Because of the mechanism of self-locking upon short circuit, the circuit breaker can not be closed directly after the circuit breaker trips upon an occurrence of short circuits, which can remind the operator that a short circuit occurred and the circuit breaker should be closed after the problem is found out and solved. The present invention not only maintains all the functions of the conventional circuit breaker, but also adds a function of self-locking upon short circuit so as to overcome the shortcoming of the prior art that the circuit breaker is damaged or a fire is started for reclosing the circuit breaker after the short circuit.
