Problems solved by technology

[0003] During the use of the circuit breaker, it is generally installed in the panel, and only the manual switch part is exposed. In general, after the circuit breaker is installed in place, another panel should be covered to prevent it from falling out. When multiple circuit breakers need to be installed at the same time , the assembly process is cumbersome; and when the manual switch of the circuit breaker fails, because the internal circuit connection is normal, there is a safety hazard in the replacement process

Abstract

The invention provides a 5G hydraulic circuit breaker and an unlocking mechanism thereof. The unlocking mechanism comprises a push rod, a positioning piece, a linkage piece, a first elastic piece, a second elastic piece and a third elastic piece, the positioning piece is embedded in a through hole in the top of a circuit breaker shell, the positioning piece is connected with the second elastic piece, and the positioning piece can be driven by the second elastic piece to rotate; therefore, the through hole extends out of the circuit breaker shell or contracts into the circuit breaker shell. Oneend of the first elastic piece is connected with the operating end of the push rod, and the other end is connected with the positioning piece through the second elastic piece; one end of the linkagepiece is hinged to the side wall of the circuit breaker shell through the third elastic piece, and the other end of the linkage piece extends towards one side of an armature of a tripping mechanism. The operating end of the push rod abuts against the third elastic piece. The positioning piece, the linkage piece and the push rod are linked through the elastic pieces, and the circuit breaker can bedisassembled and assembled under the condition that a movable contact and a static contact are disconnected.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to an unlocking mechanism of the circuit breaker and a hydraulic electromagnetic circuit breaker for 5G with the unlocking mechanism. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and close, carry and break current under abnormal circuit conditions within a specified time; stream protection. [0003] During the use of the circuit breaker, it is generally installed in the panel, and only the manual switch part is exposed. In general, after the circuit breaker is installed in place, it is necessary to cover a panel to prevent it from falling out. When multiple circuit breakers need to be installed at the same time , the assembly process is cumbersome; and when the manual switch of the circuit breaker fails, because the internal circuit connection is normal, there is a safety hazard in the replac...
