摘要
列车供电系统结构复杂,拖车漏电流误报警问题一直困扰着各研发单位和运用部门。文章针对一起典型的拖车漏电流误报警故障,从列车供电原理出发,分析了产生漏电流误报警的原因,并提出了解决办法,为160 km/h动力集中动车组的稳定运行提供保障。
The structure of train power supply system is complex,and the false alarm problem of leakage current for passenger car puzzles R&D unit and application departments.Based on the principle of train power supply,this paper analyzes the false alarm cause of leakage current in a typical passenger car.The solution is put forward to ensure the stable operation for 160 km/h power concentrated EMU.
