地铁车辆基地库内专用回流轨平面布置方式标准化设计研究

Study on Standardized Design of Special Return Rail’s Layout in Metro Depot

摘要: 专用轨回流作为一种可以彻底解决杂散电流问题的新型供电制式已经被越来越多的城市轨道交通所采用。但由于车辆检修时需要对车辆转向架等重要部件进行仪器检测，部分检修还需要登车作业，所以车辆基地库内回流轨的布置，不可避免的会给车辆检修造成一定影响。针对这一现象，本文根据实际项目经验及多方考察，提出了一种兼容多种车型的车辆基地库内专用回流轨的平面布置方式，仅需通过车辆长度、库内线路长度等参数即可确定回流轨的安装位置和安装长度。该方式可以最大程度的减少库内回流轨的布置对车辆检修的影响，提高车辆的检修效率且有利于实现检修库房的标准化设计，工程实用性较好。

Abstract: As a new type of power supply system which can completely solve the problem of stray current, the return current of special rail has been adopted by more and more urban rail transit. However, due to the inspection of important components such as Bogies and other important parts of the vehicle during vehicle maintenance, some maintenance also requires boarding operation, so the layout of return track in the depot of the vehicle base will inevitably have a certain impact on vehicle maintenance. In view of this phenomenon, according to the actual project experience and multi-party investigation, this paper puts forward a plane layout mode of special return track in the depot of vehicle base which is compatible with various vehicle types. The installation position and length of return track can be determined only by the parameters such as vehicle length and line length in depot. This method can reduce the impact of the layout of return track on vehicle maintenance to the greatest extent, improve the maintenance efficiency of vehicles, and is conducive to the realization of standardized design of maintenance warehouse, with good engineering practicability.
