普速与CTCS-2客运专线车站特殊站联电路工程设计

Design of Special Liaison Circuit between Stations of Conventional Line and Passenger Dedicated Line with CTCS-2 System

结合秦沈沟海联络线的工程应用实例,当客运专线车站与普速车站区间设有通过信号机,且客运专线车站所辖区间采用CTCS-2级列控系统编码,而普速车站所辖区间采用无绝缘轨道电路继电编码时;为满足普速车站站内联锁及电码化对离去轨继电器的要求,设计出了两种解决方案,对类似工程设计具有借鉴意义。

Combining with the engineering of the connecting line between Qinshen and Gouhai line,when the block signals are set on the sections between the stations of passenger dedicated line and conventional line,the sections belong to the stations of passenger dedicated line adopt CTCS-2 train control system coding,and the sections belong to the station of conventional line adopt UM71 jointless track circuit relay coding.In order to meet the requirement for the departure track relays by in-station interlocking and coding of the conventional line,the paper provides two solutions to the special liaison circuit between stations,which may be referenced by similar projects.
