| 摘 要： | ZPW-2000A轨道电路小轨电压反映调谐区的状态。一是日常出现的波动原因较多,造成现场不容易查找;二是发生故障时,对小轨电压关注分析不够,造成查找故障走弯路。结合现场经验及案例,利用信号集中监测数据及曲线,分析小轨电压波动、异常成因。

| Abstract: | The small rail voltage of ZPW-2000 A track circuit reflects the state of tuning zone.Firstly,there are many reasons for daily fluctuation,which makes it difficult to find the fault on site;secondly,when the fault occurs,the attention paid to the small rail voltage analysis is not enough,which leads to the fault finding detour.In this paper,combined with field experience and cases,using the centralized signal monitoring data and curves,the causes of small rail voltage fluctuation and abnormal are analyzed. |
