6kV真空开关频繁跳闸原因分析

Analysis on Frequent Opening of 6kV Vacuum Switch

针对蒲山电厂区611开关频繁跳闸现象,详细介绍了检查分析过程,从可能的原因逐一分析、排查,最后从控制回路找到了原因,使问题得到解决,为真空开关跳闸分析提供了参考。另外,文中还总结了控制回路检查中所需注意的事项。

According to the frequent opening of Qu611 switch of Pushan power plant,this paper introduced a check and analysis process in detail, one by one to analyze and check from the possible reason.Finally,from the control circuits found out the cause,making the problem resolve.The analysis provides a reference for the abnormal opening of vacuum switch.On the other hand,this paper also summarized the problems we need pay attention in checking control circuits.
