使用高强度绝缘轨距挡板改善ZPW-2000A轨道电路低道床问题的应用

Application of Highly-strength Insulating Gauge Blocks to Improve Low Ballast Bed of ZPW-2000A Track Circuits

大秦铁路作为主要的货运重载铁路,其显著特点是以煤运为主、行车密度大、重车运行速度快等。针对其部分区段因道床环境恶劣导致的易出现红光带的问题提出使用一种高强度绝缘轨距挡板解决ZPW-2000A轨道电路低道床问题。并对使用高强度绝缘轨距挡板能够解决ZPW-2000A轨道电路低道床问题进行探讨。

Datong-Qinhuangdao Railway,a major heavy-haul freight railway in China,is characterized by coal transportation,high traffi c density and high-speed operation of heavy-haul trains.However,red-light straps are likely to occur due to harsh ballast conditions in certain sections of the railway.In this paper,the paper provides and discusses the feasibility of a solution featuring highly-robust insulated rail gauge blocks to solve the problem of low ballast resistance of ZPW-2000A track circuits.
