摘要:
当地铁接触网发生跳闸故障时,通常采用试送电的方式来判断故障区域。但是试送电的方式存在耗时长且可能导致二次短路电流损害设备的缺点。介绍了地铁接触网供电结构与馈线开关的线路测试功能,分析了采用试送电判断故障区域的处理流程。在计算并对比短路电流与线路测试电流后,提出利用直流馈线开关的线路测试功能优化故障处理的方法,有效简化了故障处置的流程。

When the trip fault occurs in metro overhead contact system (OCS), the fault area is usually judged by trial power transmission mode, which may waste the processing time and cause the secondary short-circuit current damage to equipment. In this paper, the structure of metro power supply mode and the functions of DC feeder switch line test are introduced, the fault disposal process of fault area judgment by using the trial power transmission is analyzed. Through calculating and comparing the short-circuit current with the line test current, an improved fault treatment method is proposed by using the functions of DC feeder switch line test, which effectively simplifies the troubleshooting procedure.
