Abstract

The invention relates to the field of vacuum circuit breakers, and provides a circuit breaker operating mechanism which comprises a shell, a driving component, an energy storage component, a closing limiting component, a transmission component and an opening limiting component. The driving component is used for driving the energy storage component to store energy; a cam assembly is arranged on the energy storage component; the closing limiting component is used for locking the energy storage component to limit rotation of the cam assembly after the energy storage component completes energy storage. The transmission component comprises a multi-claw crank arm, a reset elastic piece and a top shaft connecting rod. The multi-claw crank arm is in linkage with the cam assembly. One end of the reset elastic piece is rotatably arranged on the shell, and the other end of the reset elastic piece is connected with the multi-claw crank arm; a swing arm of the top shaft connecting rod is connected with the multi-claw crank arm, and the top shaft connecting rod triggers the circuit breaker to be switched on or switched off through the operating shaft; the opening limiting component is used for locking the multi-claw crank arm when the swing arm, abutting against the multi-claw crank arm, of the top shaft connecting rod rotates to exceed the highest point position. The circuit breaker operating mechanism is small in occupied space and simple in structural layout.

Description

technical field [0001] The invention relates to the field of vacuum circuit breakers, in particular to an operating mechanism of a circuit breaker. Background technique [0002] In order to protect and control the overload and short circuit of the power equipment in the high-voltage power supply and distribution system, it is necessary to configure a high-voltage vacuum circuit breaker on the high-voltage power supply and distribution system. The existing high-voltage vacuum circuit breaker mainly includes the main body of the circuit breaker and the operating mechanism. The common operating mechanism in the industry is a spring-type operating mechanism. The spring-type operating mechanism includes a casing, an energy storage member and a opening mechanism. It is arranged between the left side plate and the right side plate from left to right. The energy storage member adopts the transmission mode of vertical vertical four-bar linkage assembly. The energy storage crank and t...
