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 catenary operation for many years, the traction can continue to increase the case, the contact line electrical burn phenomenon more and more prominent. According to the theory of heat conduction, the finite element analysis software ANSYS was used to conduct transient thermal analysis of current flowing through the bow grid system through the contact resistance and the arcing of the bow grid system to understand the extent of contact line erosion. The simulation results were analyzed and the simulation results were presented The corresponding solution measures for the traction power supply system design and operation and maintenance provide a reference.
