浅析高铁牵引回流烧损轨道电路绝缘处理方法

Analysis and Treatment of Track Circuit Insulation Burned Caused by Traction Return Current in High-speed Railway

西宝高铁开通以来,牵引回流多次烧损轨道电路绝缘,给安全运输带来严重的干扰。本文结合轨道电路的故障处理及日常的维护经验,对牵引回流烧损轨道电路绝缘的处理方法及经验进行了总结。

Since the opening of Xi'an-Baoji high-speed railway, track circuit insulation has often been burned by the traction return current, which caused severe interference with transportation safety. Combined with fault handling and daily maintenance experience of track circuit, the methods and experience of handling the fault occurring in an Baoji high speed railway are summarized.
