资料介绍

铁路信号轨道电路是铁路运行控制系统的基础设备之一,对保障铁路运输安全与畅通发挥着重要的作用。轨道电路可以监督检查某一区段内的线路是否有车占用,并能检查该区段内的钢轨是否完整,通过轨道电路可以将地面信号传输给机车,进而为列车运行提供条件。铁路信号现场工作人员在日常作业中会遇到各种各样的轨道电路故障现象,轨道电路故障导致的信号升级显示会危及行车安全,轨道电路故障较长延时,会对铁路运输效率产生消极影响。文章对铁路信号轨道电路的作用、组成、分类和基本原理进行研究。结合日常工作经验和现场所处理的各类故障,并对故障进行分析,对于预防故障发生和及时处理故障具有积极意义。

Railway signal track circuit is one of the basic equipment of railway operation control system, which plays an important role in ensuring the safety and smooth flow of railway transportation. The track circuit can supervise and check whether the line in a certain section is occupied by a vehicle, and can check whether the rail in the section is complete or not. Through the track circuit, the ground signal can be transmitted to the locomotive, thus providing conditions for the train operation. Railway signal field workers will encounter various phenomena of track circuit failure in their daily operations. The signal upgrade caused by track circuit failure will endanger traffic safety, and the track circuit fault will have a long delay. Will have a negative impact on railway transport efficiency. In this paper, the function, composition, classification and basic principle of railway signal track circuit are studied. According to the daily work experience and all kinds of faults dealt with on the spot, it is of positive significance to prevent the occurrence of the faults and deal with the faults in time by analyzing the faults.
