CRH1型动车组自动过分相故障控制措施研究

Research on Control Measure of Automatic Passing Neutral Section Fault

分析引发CRH1型动车组自动过分相故障5方面原因。通过分析3起运营故障现象,揭示动车组检修质量原因导致的自动过分相异常情况以及因动车组跨速度等级线路运行暴露出的动车组软件参数缺陷,针对性提出运营控制措施和参数优化建议。

This paper analyzes five causes of automatic passing neutral section fault of CRH1 EMU.Based on analyzing three operational faults,this paper reveals the abnormal condition of automatic passing neutral section caused by the maintenance quality of the EMU,as well as the parameter defects of the EMU software exposed by the EMU skip-level operation,and puts forward the operation control measures and parameter optimization suggestions.
