摘要
以两起ZPW-2000A型无绝缘轨道电路小轨电压异常升高,造成区段红光带故障情况为案例,通过分析小轨道电压变化的原因,针对小轨电压升高情况提出维护建议,避免调谐区纳入控制检查后由于小轨电压升高导致红光带情况发生。
This article presents two cases as examples of abnormal voltage increases in the small track circuits of ZPW-2000A jointless track circuits,which led to red-light strap faults in the sections.By analyzing the causes of the voltage changes in the small track circuits,maintenance suggestions are proposed to address the voltage increases,in order to avoid red-light straps caused by the voltage increases in the small track circuits after the tuning zones are included in the control inspection.
