地铁停车场和车辆段杂散电流实测与分析

摘要

正线钢轨泄漏的杂散电流所造成的车辆段和停车场内设备烧损和挂地线打火等问题在城市轨道交通中日益凸显.为此,以某地铁停车场和车辆段线路的实测数据为依据,评估杂散电流的严重程度,分析杂散电流的流通路径,并针对该地铁线路杂散电流现状提出相应的改进措施.%Due to the track stray current,problems like metro depot and parking lot equipment burning loss and sparking for aerial earth wire have become increasingly serious. Based on the measured data of a practical subway parking lot and de-pot,the severity of stray current is assessed,the flow path of stray current is analyzed,corresponding improvement measures are proposed regarding the stray current situation on that sub-way line.
