解决倒母线操作中双母接线母联开关误拉的方法

摘要

文章介绍了目前安徽省电力公司检修公司所辖十七座500千伏变电站220千伏双母接线在进行倒母线操作中存在漏倒间隔的危险，提出了可以在技术上实现防止误拉母联开关的方法。此方法对所有双母线接线的变电站在倒母线操作中漏倒间隔都具有指导意义。%The paper analyzes the danger of missing electrical separation during double-bus-switching op-eration of double-bus of 220 kV system in 500 kV substations which are under the jurisdiction of Mainte-nance Company of Anhui Electric Power Corporation, presents the available technology method of preven-ting false switch-off of bus-bar switch. This technical scheme also applies to any other substations with double-bus mode, so as to improve the safety and reliability of power grid.
