动车所内接触网防雷改造方案研究

Research on Lightning Protection Renovation Plan for Contact Network in High-Speed Train Depot

动车所是高速动车组列车的维修、保养和调度中心,其主要职责是负责对高速动车组进行日常检修、定期保养、故障排除和恢复等工作。随着高速铁路运营里程及客运量的增长,动车所内接触网雷击跳闸时有发生,部分沿海多雷区动车所1年内多次出现雷击跳闸,甚至造成线索烧损,引起动车晚点。为确保动车所内接触网供电设备的安全,结合高速铁路正线防雷相关措施,研究动车所内多线接触网防雷方案,以降低动车所内雷击事件发生率。

The high-speed train depot is the maintenance,upkeep,and dispatch center for high-speed trains.Its main responsibilities include daily maintenance,regular maintenance,troubleshooting,and recovery of high-speed trains.With the increase in the operating mileage and passenger volume of high-speed trains,lightning trips have occurred in the overhead contact system of high-speed train depot.In some coastal areas with multiple lightning strikes,high-speed train depot have experienced multiple lightning trips within a year,even resulting in burnt clues and causing delays in high-speed trains.To ensure the safety of the power supply equipment for the overhead contact system in the high-speed train depot,combined with the lightning protection measures for the high-speed trains main line,a multi line overhead contact system lightning protection scheme is studied to reduce the incidence of lightning strikes in the high-speed train depot.
