摘　　要：受电弓与接触网(简称弓网系统)动态受流是通过滑动接触实现的,因此在弓网运行的过程中势必会带来接触线和受电弓滑板的机械磨耗和电气磨损,因此有必要结合弓网系统运行的实际工况,分析影响接触线和受电弓滑板磨耗的主要原因,找出相应的对策。文章基于接触线和滑板的实际磨耗状态,设计一套试验系统,在线测试可能影响接触线和滑板磨耗的技术参数,分析该实际线路中造成二者磨耗的主要原因,并提出改善建议。The dynamic current-collecting is achieved by sliding contact of the pantograph and catenary system. So when the pantograph and catenary system is in operation, it will inevitably lead to mechanical wear and electrical wear of both contact wire and contact strip. Therefore it is necessary to analyze the main causes of wearing according to actual working conditions, and develop the according technical solution. A testing system was designed based on the actual wear state of contact wire and strip in this paper, analyzing the main cause of wear for both of them in the subway lines, and suggestions for improvement are put forward by line testing the technical parameters which might affect wear of contact wire and contact strip.
