摘　　要：列车在经过分相时产生的电磁暂态干扰会引起接触网隔离开关击穿,造成馈线跳闸、避雷器频繁动作等问题,若处理不当可能影响铁路正常运输,甚至引发安全事故,因此对列车过电分相引发的暂态过电压进行分析并提出解决方案具有重要的现实意义。本文针对实际案例对列车过分相产生的暂态过电压机理进行分析,提出抑制措施,并在实际工程中得到验证。The electromagnetic transient interference generated as the train passing through the neutral section can cause the breakdown of the OCS disconnector;resulting in tripping of feeders,frequent operation of lightning arresters,and other problems.If not handled properly,it may affect the normal transportation of the railway and even cause safety accidents.It is of great practical significance to analyze the transient overvoltage caused by train passing through the neutral section and propose solutions.The paper analyzes the transient overvoltage mechanism caused by train passing through the neutral section with reference of the actual cases,proposes suppression measures,which are verified in practical engineering.
