摘　　要：ZPW-2000制式无绝缘轨道电路是我国高速铁路CTCS-3级列车运行控制系统的必不可少的基础设备,轨道电路系统承载着列车占用位置检查、车载ATP(机车信号)电码化信息传输、牵引供电回流泄放等功能,因轨道电路工作环境及信号传输工作特性,要求不得出现侵入信号干扰本区段信号,以典型案例为引入,分析邻区段干扰的形成因素,并采取措施解决。ZPW-2000 jointless track circuit is an indispensable part of CTCS-3 train operation control system of high-speed railway in China.The track circuit system bears the functions of train occupancy position check,on-board ATP(cab signal)coded information transmission,traction power supply backfl ow and discharge,etc.Due to the working environment of track circuit and the working characteristics of the signal transmission,it is required that there should be no intrusion signal interfering with the signal in this section.This paper introduces typical cases to analyze the formation factors of interference in adjacent sections,and fi nds out measures to solve them.
