摘要
轨道电路作为铁路信号系统中重要的组成部分,起到了区段占用检查与机车发码的功能。随着中国铁路运营速度不断增加,轨道电路制式由25 Hz轨道电路、UM71轨道电路逐步升级为ZPW-2000系列轨道电路。本段管内某站站内轨道常因分路不良导致进路漏解锁,影响高速列车的进路排列。为解决该类隐患,电务部和电务段采用了ZPW-2000A·TM移频脉冲轨道电路。本文介绍轨道电路原理,通过分析现场运用情况,探讨移频脉冲轨道电路的特征与运用效果,对车站站内轨道电路的应用具有实际的应用价值和工程指导意义。
As an important part of railway signal system,the track circuit plays the role of section occupancy check and locomotive code sending.With the increase of railway speed in China,the track circuit standard has been gradually upgraded from 25Hz track circuit and UM71 track circuit to ZPW-2000 series track circuit.Frequent unlocking of tracks due to inadequate ballast compaction adversely impacts high-speed train route alignment.To address this safety concern,the telecommunication department and the station have implemented a solution by adopting ZPW-2000A•TM frequency shift pulse track circuits.Based on the analysis of field applications,this paper discusses the characteristics and applications of the frequency shift pulse track circuit,which is of practical value and engineering significance for the application of station track circuit.
