一次大型异物导致220kV变电站母线失压故障分析

Failure Analysis of Large Foreign Bodies Causing 2 2 0 k V Substation Bus V oltage Losing

针对大型异物导致220 k V变电站母线失压故障进行了分析,提出了大型异物有可能对不同电压等级的变电站的运行安全造成威胁,因而在大风天气、放飞风筝以及孔明灯情况下要做好相应的巡视与事故预案。

This paper analyzes 220 k V substation bus failure losing caused by large foreign objects, puts forwards that large foreign objects are likely to cause threat for safety operation of substation with different voltage class. Thus in windy weather, corresponding patrol and accidents prevention program should be conducted under the condition of kites and kongmin light flying cases.
