摘　　要：多股道站场接触网由于结构复杂、分支众多,发生接地故障后,依据现有的故障测距技术,无法确定故障的具体股道与位置。针对这一问题,提出一种多股道站场接触网故障定位方法。在每一分支股道对应的承力索上安装多个电流监测终端,并采集电流波形数据。利用ZigBee无线通信技术汇集数据,通过电流有效值的大小判断区间内存在故障,通过相邻电流监测终端采集的相反方向电流定位故障区段,实验结果验证了该方法的有效性与正确性。Due to the complex structure and numerous branches of the catenary of multi⁃track yard,the specific track and location of the fault cannot be determined with the existing fault location technology after the grounding fault occurs.Therefore,a fault location method for multi⁃track yard catenary is proposed.Multiple current monitoring terminals are installed on the messenger cables corresponding to each branch track,and current waveform data are collected.ZigBee wireless communication technology is used to assemble data.The fault in the interval is judged by the magnitude of the effective value of the current,and the fault section is located by the opposite direction current collected by the adjacent current monitoring terminal.The experimental results have verified the validity and correctness of the proposed method.
