Abstract

The invention provides a circuit breaker operating mechanism test fixture. With the circuit breaker operating mechanism test fixture adopted, an operating mechanism can be quickly tested. The circuitbreaker operating mechanism test fixture comprises a base for supporting an operating mechanism to be detected; the base is provided with a rotation testing mechanism for driving the input shaft of the operating mechanism to be detected to act to realize a closing action; the rotation testing mechanism comprises a rotating shaft that is in transmission connection with the input shaft; the rotationtesting mechanism further comprises a driving wheel disposed coaxially with the rotating shaft; the rotating shaft is fixedly provided with a cam; the driving wheel is provided with detents in a manner that the detents can swing, wherein the detents are located beside the cam; clamping openings into which the detents can be clamped into are formed in the cam; during the swing stroke of each detent, the detent has a clamping position in which the detent can be clamped into the corresponding clamping opening, and a retreat position in where the detent can retreat from the corresponding clampingopening; the driving wheel pushes the cam by the detents so as to push the rotating shaft to rotate; and a limiting slider which is matched with the detents to make the detents retreat from the clamping openings of the cam during the rotation stroke of the driving wheel is arranged in the rotation testing mechanism.

Description

technical field [0001] The invention relates to the technical field of running-in test devices, in particular to a test tool for a circuit breaker operating mechanism. Background technique [0002] The circuit breaker is an important switching device in the power system. It is used to cut off and conduct the power transmission of the grid. The operating mechanism of the circuit breaker is the power part of the circuit breaker. When the circuit breaker receives the system opening and closing signal , the operating mechanism drives the body of the circuit breaker to perform opening or closing operations, so as to realize the breaking and closing of the current. It can be said that the reliability of the operating mechanism directly affects the breaking characteristics of the circuit breaker and determines the performance of the circuit breaker. main mechanical properties. Therefore, in order to ensure the reliability of the operating mechanism, when the operating mechanism is...
