摘　　要：针对成都地铁部分线路钢轨电位限制装置接触器分闸“打火”现象分析故障原因,提出在设备分闸控制回路增加电容模块形成RC回路的优化整改方案,并通过试点测试和安装应用验证了方案的可行性。The causes of the faults of phenomenon of“flashing”caused by the tripping of over-voltage protection device for rail potential is analyzed for rail potential occurred on part of Chengdu metro lines,optimized rectification scheme of supplementing of capacitor modules at the equipment tripping control circuit for forming of RC circuit is put forward.The feasibility of the scheme has been verified through test at site,installation and application.
