摘　　要：为由于电气化铁路接触网绝缘子表面积污,在恶劣天气下引起绝缘子在正常工作电压下发生污秽闪络,造成大面积和长时间的停电故障,是目前电气化铁路频发性事故之一。结合兰州铁路局管内兰新线玉门、柳沟地区发生绝缘子覆冰闪络问题影响供电设备运行的事故,对接触网绝缘防污闪的措施及改进方法进行分析和探讨。Because of electric railway Overhead Contact Line Systems （OCS） insulator surface is contaminated, in bad weather caused the insulator occur under normal operating voltages pollution flashover, caused widespread and prolonged power failure, is currently one of the hair electric railway accidents frequently. Combined with Yumen and Liugou areas of Lanxin railway because surface of insulator ice-flashover affect the normal operation of power supply equipment accident, this article analyses and discusses measures to prevent pollution flashover and improved methods of the OCS insulator.
