摘要
在车站同时存在不对称高压脉冲轨道电路和25 Hz相敏轨道电路时,因两种轨道电路制式的时间特性不一致,存在单机运行时轨道区段漏解锁、丢车、掉码的现象,对正常行车造成干扰。通过详细分析两种轨道电路制式的时间特性,对3种运营故障场景进行剖析,并针对每种场景给出不同的解决方案,对以后的工程设计具有一定的指导意义。
When there are asymmetric high-voltage pulse track circuit and 25 Hz phase-sensitive track circuit in the main line of the station at the same time,due to the inconsistent time characteristics of the two track circuit systems,there are phenomena of missing unlocking,train loss and code loss in the track section during single locomotive operation,causing interference to normal train operation.By analyzing the time characteristics of the two track circuit systems in detail,this paper analyzes three operation fault scenarios,and gives diff erent solutions for each scenario,which has certain guiding significance for future engineering design.
