鞍钢铁路接触网负极回流系统分析

简要介绍了鞍山钢铁集团铁路运输公司铁路直流接触网工作原理,通过列举典型实例,归纳分析了困扰接触网负极回流系统正常运行的缺陷。根据分析结果,通过优化钢轨回路、增设支柱接地线等措施,使鞍钢铁路接触网负极故障大幅度下降,彻底消除了接触网馈电线以及接触线烧损的事故。

Analysis on Cathode Backflow System of Railway Contact Grid in Angang

The operating principle of DC contact grid for the railway line in Railway Transport Company of Anshan Iron ＆ Steel Group Company is briefly introduced. The drawbacks which influence the normal operation of the cathode backflow system of the contact grid are analyzed inductively by listing typical living examples. Based on analytical results, power failures of the cathode backflow system of the contact grid for the railway in Angang are greatly decreased and such burning accidents of feeders and contact lines in the contact grid are removed completely by taking such measures as optimizing the circuit for the rail power line and adding pillar grounding wires.
