ZPW-2000A型无绝缘轨道电路空闲点红灯的故障时有发生,故障原因各有不同。判断此类故障的方法是对故障区段的衰耗盘各塞孔进行电气特性测试,根据测试结果进行故障分析并处理。在现场处理轨道点红灯故障时,会遇到这样的情况:同一种设备故障(如衰耗盘),有时造成1个区段点红灯,有 ZPW-2000A-type non-insulated track circuit idle red light fault occurs from time to time, the reasons for the failure are different. The method of judging such a fault is to test the electrical characteristics of each plug hole of the failure disk in the fault section and analyze and handle the fault according to the test result. When dealing with the track red light fault at the scene, we will encounter such a situation: the same kind of equipment failure (such as loss of disk), sometimes resulting in a red light section, there
