Abstract: Insulation joint is the joint of public works and electricity, and it is an important part of track circuit. This paper discusses the function and daily inspection operation standard of bonded insulation joint, and summarizes the causes of common diseases, treatment methods and emergency treatment after insulation joint failure, in order to provide reference for on-site treatment of insulation joint disease.
Keywords: cemented insulation joint; cementation disease; treatment method; emergency treatment
钢轨绝缘接头的作用是分割两相邻轨道中的信号电流,通过对信号电流的断路和短路来控制钢轨中的电流是否被接通,断路时表示无车占用轨道,轨道空闲,可以接发列车;短路时表示有车占用轨道,车间轨道监控系统产生红光带,无法接发列车,通常现场以信号灯显示红灯,这是铁路信号指挥系统的基础设备。(剩余5399字)
