Abstract

Abstract: The features, structure and actuation principle of permanent magnetic mechanism were analyzed in detail by comparison of advantages and disadvantages of various operation mechanisms of medium voltage vacuum circuit breaker. And it was proved that the application of permanent magnetic mechanism in the 6～40.5kV medium voltage vacuum circuit breaker is very important for the development direction, the target of which is to make maintenance-free products.

Key words: permanent magnetic mechanism, medium voltage vacuum circuit breaker, advantage, application
