摘　　要：针对某地铁项目出现的接触网异常磨耗问题,对异常磨耗现状及磨耗情况进行统计分析,从接触网方面和车辆方面进行相关设备排查,确定造成异常磨耗的直接原因为高温与燃弧导致的电气磨损,并制定了相应的干预措施,有效地控制了弓网异常磨耗的进一步恶化。In view of the abnormal wear problem of catenary in a metro project,the present work carried out statistical analysis of abnormal wear status and wear values,and equipment survey from the perspectives of both catenary and vehicles.It successfully determined that the direct cause of abnormal wear was electrical wear caused by high temperature and arc combustion,and formulated the corresponding countermeasures which helped significantly suppress the further deterioration of abnormal wear of catenary.
