摘要
随着铁路运输需求量迅猛增加,需要对既有线铁路提速以满足运输需求。为适应提速改造工程装备CTCS⁃2级列控车载设备动车组列车既有线运行安全要求,既有线信号地面设备尤其是轨道电路需配套进行改造。以安九高铁为例,通过对既有京九铁路(孔垄至九江段)区间ZPW⁃2000轨道电路主轨入电压监测年曲线分析、软件模拟仿真,推算区间道床电阻最小值来计算相应区段长度调整表,实现既有线铁路信号列控系统升级改造后能满足轨道电路技术条件需求。
With the rapid increase of railway transportation demand,it is necessary to speed up the existing railway line to meet the transportation demand.In order to meet the safety requirements of existing line running on EMU trains equipped with CTCS⁃2 train control equipment,the signal ground equipment of existing line,especially the track circuit,is reconstructed.Taking the Anqing⁃Jiujiang High⁃speed Railway as an example,the monitoring annual curve and software simulation of the main rail voltage of ZPW⁃2000 track circuit between Konglong and Jiujiang section of the existing Beijing⁃Kowloon Railway are presented,the minimum value of the resistance of the track bed is deduced to calculate the adjustment table of the length of the track,so as to meet the requirement of the technical conditions of the track circuit in the upgrading and reconstruction of the signal train control system of the existing railway.
