摘　　要：[目的]接触网设备作为供电系统中无冗余设备,一旦发生故障会严重影响列车的正常运营。在上海轨道交通线网中,刚性接触网线路占正线比重较大,作为线路中关键设备的刚性接触网锚段关节,其磨耗、燃弧等故障频繁发生。需分析其故障原因并对其进行优化。[方法]基于上海轨道交通刚性接触网故障数据,分析了刚性接触网锚段关节磨耗、燃弧等故障发生的原因;从加速取流段优化、技术参数优化、汇流排挠度优化提出了具体的锚段关节优化措施。[结果及结论]刚性接触网锚段关节优化后,提升了设备可靠性,有效减缓了磨耗速率,降低了人员维护成本,减少了物料消耗。[Objective]As non-redundant equipment in power supply system,catenary equipment can significantly affect the normal operation of trains when faults occur.In the Shanghai rail transit network,rigid catenary lines account for a significant proportion of the main line.As the critical equipment in the line,rigid catenary anchoring overlap joints frequently experience faults such as wear and arcing.It is necessary to analyze the causes of these faults and optimize them.[Method]Based on fault data,from the rigid catenary system in Shanghai rail transit,the causes of faults such as wear and arcing in rigid catenary anchoring overlap joints are analyzed.Specific optimization measures for the anchoring overlap joints are proposed,including optimizing the acceleration current collection segment,technical parameter optimization,and busbar deflection optimization.[Result&Conclusion]After optimizing the rigid catenary anchoring overlap joints,the reliability of the equipment is improved,the rate of wear is effectively reduced,maintenance costs are lowered,and material consumption is reduced.
