Abstract

The invention discloses a circuit breaker closing and locking device which comprises an insulating shell, a closing push rod, a return spring and a locking body. A top wiring seat and a bottom wiringseat are arranged on the upper surface and the lower surface of the insulating shell, the top wiring seat is electrically connected with conductor rods inside the insulating shell, upper contacts arearranged at the bottoms of the conductor rods, a lock key is arranged on the lower portions of the conductor rods, lower contacts which are matched with the upper contacts are hinged onto the lock key, an end of the lock key is connected with the closing push rod by the return spring, the closing push rod is inserted in the insulating shell, the locking body is arranged inside the insulating shell, is positioned on the upper portion of the closing push rod and comprises an electromagnet, an electromagnetic coil and a movable electromagnet iron core, the electromagnet is arranged inside the locking body, and the electromagnetic coil is wound on the surface of the electromagnet. The circuit breaker closing and locking device has the advantages that the circuit breaker closing and locking device with double locking devices is high in closing and locking safety, circuit faults can be conveniently checked by staffs, and timely maintenance can be facilitated.

Description

technical field [0001] The invention relates to the technical field of closing and locking of a circuit breaker, in particular to a closing and locking device for a circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy and start asynchronous motors infrequently. It can automatically cut off the circuit when serious overload, short circuit and undervoltage faults occur. Its function is equivalent to the combination of fuse switch and overheatin...
