Abstract

The invention discloses an operating mechanism for a circuit breaker. The operating mechanism for the circuit breaker comprises a switching-on module unit and a switching-off module unit. The switching-on module unit is composed of a left side board, a right side board, an energy storage motor, an energy storage compression spring, a crank arm, an energy storage shaft, a cam, a chain wheel, a tripping shaft, a trigger, a microswitch, a switching-on electromagnet and an energy storage sign board. The switching-off module unit is composed of a left side board, a right side board, one or more tripping electromagnets, a switching-off half shaft, a pinch plate, a trigger and a switching on / off sign board. The operating mechanism for the circuit breaker has the advantages that the operating mechanism is practical and low in production cost, and the spring operating mechanism of the circuit breaker is combined into a modularized unit, is independent from the circuit breaker, and is integrally assembled and disassembled conveniently; a switching on module and a switching off module in the modularized operating mechanism can be independently assembled in advance and are each of one specification, and therefore the variety and the number of spare parts and stored parts are both greatly reduced, and the production efficiency of products is improved.

Description

technical field [0001] The invention relates to a mechanism for a circuit breaker, in particular to an operating mechanism for a circuit breaker. Background technique [0002] At present, the operating mechanism for indoor medium-voltage embedded vacuum circuit breakers is a spring operating mechanism arranged in a plane, with manual energy storage and electric energy storage. The operating mechanism is placed in the chassis in front of the arc extinguishing chamber, and the chassis is surrounded by The partition is divided into five assembly spaces, in which the energy storage part, the transmission part, the trip part and the buffer part of the operating mechanism are respectively installed. The disadvantages of this structural design are that there are complex structures, many transmission links, high requirements for parts, and the replacement and maintenance of parts are quite troublesome, and the product reliability is poor. Contents of the invention [0003] The te...
