The invention belongs to the technical field of subway power supply, and particularly relates to a two-side arrangement mode of an anode contact rail and a cathode special rail for a subway, which comprises a rail-mounted area steel rail, the rail-mounted area steel rail is mounted at the bottom of a subway tunnel, and the anode contact rail and the special rail are mounted on two sides of the rail-mounted area steel rail respectively. According to the scheme that the special rail is arranged on the opposite side of the contact rail, that is, the special rail replaces a running rail for backflow is achieved, so that the problem of stray current corrosion is solved, meanwhile, the contact rail which is installed with the positive electrode and completely universal in parts is adopted for the negative electrode, and influences on operation overhaul and resource sharing are avoided.
本发明属于地铁供电技术领域,尤其涉及一种地铁用正极接触轨与负极专用轨两侧布置方式,包括轨行区钢轨,轨行区钢轨安装在地铁隧道底部,轨行区钢轨两侧分别安装有正极接触轨和专用轨,本发明提出一种在接触轨对侧布置专用轨的方案,即实现了专用轨替代走行轨进行回流,从而解决了杂散电流腐蚀问题,同时负极采用了与正极安装形式、零部件完全通用的接触轨,避免对运营检修、资源共享造成影响。
