京广线郑州至武昌段引进信号设备UM71无绝缘轨道电路,自1992年3月全线开通以来,对于防止电化区段工频牵引电流对信号设备的干扰,减少信号设备的故障率,起到了积极的作用。但该设备自开通以来,由于对该设备性能、技术指标、工作原理等的理解与掌握不够,致使在施工及运营维修中,造成该设备的故障,本文就以该设备检修过程中,对该设备的故障及其原因作一浅显的分析与统计。 Beijing-Guangzhou line from Zhengzhou to Wuchang introduction of signal equipment UM71 uninsulated track circuit, since the opening of the entire line in March 1992, for the electrified section to prevent the frequency of the current traction current signal equipment to reduce the failure rate of signal equipment, has played a positive Role. However, since the equipment was opened, due to the equipment performance, technical indicators, working principle understanding and mastery is not enough, resulting in the construction and operation and maintenance, causing the equipment failure, this article on the equipment maintenance process, the Equipment failure and its causes for a simple analysis and statistics.
