摘　　要：在接触网运行了多年、牵引运能不断增加的情况下,接触线的电气烧伤现象越来越突出。本文依据热传导理论,利用ANSYS大型有限元分析软件对弓网系统电流通过接触电阻时和弓网系统产生电弧时进行瞬态热分析,了解接触线被侵蚀程度,分析仿真结果,并根据仿真结果提出了相应的解决措施,为牵引供电系统的设计和运营维护提供参考。In the case of catenary operation for many years and traction transport capacity increasing, the electrical burns of the contact line has become increasingly prominent. We based on heat conduction theory in this paper. We carried out an transient thermal analysis by using ANSYS finite element analysis software when the current in the bow net system flows through the contact resistance and when the bow net system produce electric arc. We obtained the erosion of the contact line, analyzed the simulation results, put forward corresponding solutions according to the simulation results and provided a reference for design and operation and maintenance of the traction power supply system
