摘要
占用丢失是ZPW-2000A轨道电路应用过程中非常严重的技术难题,会导致铁路信号升级,严重影响行车安全。将从调整不当、分路不良、迂回回路和信号干扰4个方面成因并结合实际案例对ZPW-2000A轨道电路占用丢失问题进行分析探讨。
Loss of occupancy is a very serious technical problem in the application of ZPW-2000A track circuit,which will lead to the upgrade of railway signals and seriously affect the safety of driving.This paper analyzes and discusses four causes of the problem of ZPW-2000A track circuit occupancy loss,including improper adjustment,bad shunting,detour loop and signal interference on the basis of actual cases.
