The operating mechanism action reliability of miniature circuit breaker was studied.The action reliability of miniature circuit breaker was investigated and the mechanism action reliability model was built at the overload breaking moment by using Monte Carlo method of mechanism reliabilG ity design theory.Meanwhile,the action reliability sensitivity of mechanism was analyzed,which gave out the variation laws of random parameters reliability sensitivity and the impacts of random parameG ter changes to operating mechanism action reliability.The analytical results indicate that the method used herein can analyze action reliability of miniature circuit breaker operating mechanism effectively and provide a basis for the design of miniature circuit breaker operating mechanism as well.
