摘 要：在断路器的各个部件中，机构部件对于多项性能指标具有重要作用。运用 ADAMS 仿真软件对 HTW65 万能式断路器出现故障后机构再合闸瞬分的现象进行仿真研究，发现了产生机构合闸瞬分的原因是机构的复位反弹时间小于控制器的磁通信号释放时间， 造成二次合闸瞬分的现象。提出了有效的改进方案，并对改进后制作的样机进行了试验验证，结果表明改进方案有效解决了故障后机构再合闸瞬分的问题。

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
