摘　　要：本文针对三岔至神池南间贯通区段线路在送电时,馈线开关瞬时电流速断保护误动作、致使线路造成停电事故进行分析,提出科学、合理的解决方案和实施措施,利用自动重合器技术来解决因电流速断跳闸而引起整条馈线停电,避免了对整个区段的铁路信号备用电源、行车数据采集、设备检测以及生活用电的影响,从而提高配电供电的可靠性和安全性。In view of the power supply of through section line from three bifurcation to south of Shenchi,analysis of feeder switch instantaneous velocity fault protection mis-operation,which results in the power out.age accidents in this article is made, scientific and reasonable solutions and implementation measures areput forward,using the automatic reclosing technology to solve fault tripping the whole feeder power outagethat caused by current instantaneous,to avoid the influence of the whole section of the railway signal stand.by power supply,traffic data collection,equipment testing and the life-use power,thus to improve the reli.ability and security of distribution and power supply.
