摘　　要：ZPW-2000A轨道电路作为主要的区间闭塞信号设备在全路得到了广泛应用.设备的正常工作对铁路运营生产起着至关重要的作用.S P T铁路信号电缆作为Z P W-2000A轨道电路的重要组成部分,同时也是故障问题多发点.通过对某站现场发生的ZPW-2000A轨道电路电缆断线但是未红轨的故障问题进行简要分析,简述移频信号在SPT信号电缆中的传输特性.给电务人员在处理电缆故障相关问题提供一些思路.ZPW-2000A track circuit is widely used as the main sectional block signaling equipment in the whole railway.The normal operation of equipment plays a vital role in railway operation and production.SPT railway signaling cable is an important part of ZPW-2000A track circuit,but also a frequent point of failure.This paper briefl y analyzes the disconnection fault of ZPW-2000A track circuit cable but not red track in a statio,and describes the transmission characteristics of frequency shift signal in SPT signal cable,which provides some ideas for the signaling&communication personnel in dealing with the problems related to cable faults.
