摘要
研究目的:当供电线发生永久故障情况时,不仅牵引变电所馈线侧自动重合闸会失败,还会给变电所高压设备带来较大的电流冲击,缩短高压电器设备的使用寿命。研究结论:(1)牵引变电所馈线故障判断装置能够对故障线路的故障性质(永久故障或瞬时故障)进行自动测量判别;(2)测量结果对馈线保护自动重合闸装置实施选择性闭锁,能有效地避免在接触网发生永久故障下自动重合闸的盲目性。
Research purposes： When the power line with feeder circuit breaker will fail , but also will bring a greater and shorten the service life of these devices. permanent fault , not only the automatic reclosing of the current impact to the high - voltage equipment of substation Research conclusions： Traction substation feeder fault judge equipment can measure and judge the fault types （permanent failure or transient failure） automaticlly. According to measurements of selective blocking on the auto - recloser automatics , avoid the blindness of the automatic reclosing action when the catenary with permanent fault.
