大秦站内ZPW-2000A轨道电路漏解锁的分析和解决方案

大秦线2亿t扩能改造工程在站内使用了和区间轨道电路相同制式的ZPW-2000A轨道电路,室内电路也大体相同。而区间电路模式的简单套用不适应站内的复杂情况,个别站出现了轨道区段漏解锁问题。本文对该问题进行分析,并给出了解决方案。

Analysis and Solution of Intra-station ZPW-2000A Track Circuit Missing Release on Daqin Line

In the project of 200 Million Tons Capacity-Expansion Reconstruction for Daqin Railway, ZPW- 2000A track circuit is adopted in intra-station with the same standard and indoor circuit as the track circuit in section. However, as the intra-station conditions are more complex, the circuit mode in section is not applicable to intra-station, and the problem of track section missing release is occurred in a few stations. This paper analyzes the problem and puts forward the relevant solutions.
