Abstract: Among all the parts of circuit breakers, the mechanism part plays an important role in a number of performance indexes. The simulation software ADAMS is used to simulate the mechanism re-closing instant breaking of HTW65 universal circuit breaker after the failure occurs to it. According to the simulation, the cause of the mechanism closing instant breaking is that the reset rebound time of the mechanism is less than the release time of the controller flux signal, which leads to the phenomenon of re-closing instant breaking. An effective improvement scheme is proposed, and the improved prototype is tested and verified. The results show that the improved scheme effectively solves the problem of mechanism re-closing instant breaking after the failure occurs.
Key words: universal circuit breaker; anti-bounce device; controller; bounce time
