切换电容接触器切换时序的分析

Analysis of the Switching Time Sequence of Capacitor Switching Contactor

本文介绍了切换电容器式接触器的限流触头与主触头切换时序重要性及其影响因素,并对每种因素的影响做了分析。针对几种重要的影响因素提出了改进方案,并进行了实验验证。试验证明改进后的切换时序、抑制涌流能力及电寿命有明显的提升。

Factor influencing the switching time sequence between current limiting contacts and main contacts which are assembled on a capacitor switching contactor,have been introduced.And the influences of these factors also have been analized.This paper also puts forward the improvement scheme which will optimize the switching time.The scheme has been proved effective by experiment and the switching time sequence,suppression of inrush current and electrical endurance have been promoted obviously.
