摘　　要：针对一起35 kV变电站站用交流失压事件,对站用自动转换开关双电源切换装置的常见故障原因进行分析,并提出防范措施。事件分析结果表明该变电站失压导致1、2号所变低压侧同时失电,从而造成自动转换开关切换失败,具有一定特殊性,可为变电站运维工作提供参考。In allusion to an event of service AC voltage loss in a 35 kV substation,analysis is conducted on the common causes of faults in the dual power switching device of service automatic transfer switch,and the corresponding preventive measures are proposed.The analysis results on the lower-voltage side of No.1 and No.2 transfers in the substation,which brings about the automatic transfer switch switching failure of a certain particularity,available for reference in the operation and maintenance of substations.
