基于分层归类法的25 Hz相敏轨道电路故障诊断与分析

Faults Diagnosis and Analysis of 25Hz Phase Detecting Track Circuits Based on Hierarchical Classification

铁路向着高速、重载和高效运输的方向发展,对铁路信号安全可靠水平的要求越来越高。轨道电路作为铁路信号的基础设备,已逐渐成为影响铁路运输效率的关键问题。本文通过对25 Hz相敏轨道电路故障诊断问题进行归类分析,介绍了故障排除方法、步骤和可能的故障点。实现故障快速准确定位,为电务部门的维修提供一定的现实指导意义。

With development of railways towards high-speed, heavy load and high transportation efficiency, requirements of safety and reliability of railway signaling are also increasing. As the basic equipment of railway signaling, track circuits have gradually become the key problem of railway transportation eff^ciency. By classifying and analyzing 25Hz phase detecting track circuit faults, the paper introduces possible faults and methods of troubleshooting and steps, in order to realize rapid and accurate fault location and to provide practical guidance for maintenance by signaling and communication department.
