摘　　要：随着我国电气化轨道交通的快速发展,轨道交通网络覆盖域越来越广,列车穿梭于不同的地域环境中,在特殊的气候条件下接触网运行容易出现污闪、过压、滤波和通信干扰等情况而造成故障,使接触网出现拉弧现象,甚至造成弓网事故,将引起列车晚点和破坏运营安全.本文结合变电所主接线案例探索故障诊断的原因,用于在供电接触网设备故障维护时保存记录,并建立完善的数据库管理或案例相似法则,可有效的解决接触网故障检测与诊断的难题,为铁轨道交通安全运营提供了一项可靠的技术保障.With the rapid development of high - speed electrified railway in China, the opening and operation of high - speed rail network can be summarized as ＂four vertical and four horizontal＂. Under special weather conditions, the operation of OCS is prone to pollution flashover, overvoltage, filtered and communication interference, make contact net appear are pulling phe- nomenon, serious damage caused by Contact network system, train running out of power, will cause train delays and damage safety operations. This paper combines substation main wiring case to explore the causes of fault diagnosis, record for mainte- nance of power supply contact network equipment failure, and establish database management or case similarity rules, which provides a reliable technical guarantee for the safe operation of rail transit.
