摘 要:在斷路器的各個部件中,機構(gòu)部件對于多項性能指標具有重要作用。運用 ADAMS 仿真軟件對 HTW65 萬能式斷路器出現(xiàn)故障后機構(gòu)再合閘瞬分的現(xiàn)象進行仿真研究,發(fā)現(xiàn)了產(chǎn)生機構(gòu)合閘瞬分的原因是機構(gòu)的復(fù)位反彈時間小于控制器的磁通信號釋放時間, 造成二次合閘瞬分的現(xiàn)象。提出了有效的改進方案,并對改進后制作的樣機進行了試驗驗證,結(jié)果表明改進方案有效解決了故障后機構(gòu)再合閘瞬分的問題。

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
