摘要
UM71无绝缘轨道电路是法国CESS公司研制的U型(带调制)移频轨道电路。铁道部于1989年郑武线四显示改造通过技贸结合方式引入中国,该系统符合中国铁路运输向重载、高速、高密度发展的需要,广泛用于中国铁路几大干线。对提高中国铁路运输效率,保证行车安全起到了显著作用。论文列举了两个现场典型故障进行分析阐述,从故障现象、处理过程、原因分析、故障分析启示四个方面进论述,以供维修人员参考。
UM71 jointless track circuit is the France CESS company developed U （modulation） frequency shift track circuit.The railway ministry in 1989, Zheng Wu line four through the combination of technology and trade show transformation into China, which conforms to the Chinese railway transportation to the heavy load, high speed, high density development needs, are widely used in China Railway Major trunk.On improvement of China railway transport efficiency, guarantee the safety of train has played a significant role.The paper cited the two typical fault analysis, from the fault phenomena, process, cause analysis, fault analysis and Enlightenment four respects to discuss, for repair personnel reference.
