摘要
500kV上河变50522隔离刀闸长时间燃弧,产生过电压,造成线路阻波器中避雷器和调谐元件损坏,并在二次刀闸操作回路产生感应过电压,使加热器电源开关击穿。从理论上对故障的机理进行分析,并提出解决措施。
Due to the arc ignition happened on50522Disconnected Switch for a long time in500kV Shanghe Substation,the over voltage is produced,arrester and the tuning device in the Line Trap are damaged,and induced over-voltage in the disconnected switch control operation circuit is also produced.This paper analyzes the mechanism of fault and presents the solving measures.
