220kV母线电压二次回路并列反充电情况分析

摘要

This article through the analysis of a substation 220kV II, III section of bus potential transform- er secondary parallel reverse charging anomaly, sums up the causes of potential transformer secondary re- verse charging, analyzes the effects of this situation on safety production, and puts forward the prevention measures.%本文通过对某变电站220kVⅡ、Ⅲ段母线压变二次并列反充电的异常情况进行分析,总结出压变二次反充电的原因,同时分析了压变发生二次反充电对安全生产的影响,并提出预控措施。
