摘　　要：新建铁路验收阶段,接触网燃弧是动态验收中的常见问题。接触网燃弧现象对接触网的性能影响较大,并影响线路最终CDI得分评价。通过结合2023年开通的川青铁路三星堆至镇江关段、2024年开通的川青铁路镇江关至黄胜关段接触网燃弧整治,深入分析燃弧产生的原因,制定相应的预防、处置措施,确保接触网系统、弓网系统运行正常。During the acceptance stage of a new railway,arcing of the overhead contact system is a common problem in dynamic acceptance.The phenomenon of arcing in the overhead contact system has a significant impact on its performance and affects the final CDI score evaluation of the line.This article analyzes the causes of arcing in the overhead contact system of the Sanxingdui to Zhenjiangguan section of the Sichuan Qinghai Railway,which will be opened in 2023,and the Zhenjiangguan to Huangshengguan section of the Sichuan Qinghai Railway,which will be opened in 2024.Corresponding prevention and disposal measures are formulated to ensure the normal operation of the overhead contact system and catenary system.
