铁路自闭贯通线路行波故障测距方案探索

铁路自闭贯通线路负责向沿线通信、信号、车辆等重要行车负荷设备供电,一旦发生故障造成停电将影响列车运行。基于现阶段10 kV自闭贯通线路运行现状的一系列问题,探索行波故障测距解决方案,以保证铁路自闭贯通线一旦出现故障时行波故障测距装置正确启动,快速判断故障类型和精准定位故障地点,尽快对故障进行处置,有效压缩故障停时。

The railway automatic blocking through line is responsible for supplying power to important train running loads and equipment such as communication,signaling,and vehicles along the line.If a fault occurs and causes a power outage,it will affect train operation.On the basis of a series of problems existing in the operation of the 10 kV automatic blocking through line at this stage,a solution by means of traveling wave fault location is discussed so as to ensure that the traveling wave fault location device is correctly started in case of a fault on the railway automatic blocking through line,with realization of rapid judgement of fault type and acknowledgement of accurate fault location.It is able to dispose of the fault as soon as possible and effectively compress the halt time due to the fault.
