摘　　要：为彻底解决城市轨道直流牵引供电系统杂散电流对沿线重大敏感设施造成的安全隐患,首次在城际轨道交通项目中采用专用轨回流的方式。由此带来的场段检修库牵引网方案有别于传统的走行轨回流模式,对检修库的牵引网提出新的要求。结合工程实际,对检修库内回流轨设置及静调电源取流和回流方案进行深入研究,首次提出满足工艺检修要求和牵引供电系统要求的专用轨回流模式下的检修库牵引网方案,全面总结在项目中积累的经验,为今后类似项目起到了指导和借鉴的作用。In order to completely solve the safety hazards caused by stray current in the DC traction power supply system of urban rail transit on major sensitive facilities along the line,a dedicated rail return current method has been adopted for the first time in intercity rail transit projects.The traction network scheme of the maintenance depot brought about by this is different from the traditional running rail reflux mode,and puts forward new requirements for the traction network of the maintenance depot.This article combines engineering practice to conduct in-depth research on the setting of the return rail in the maintenance shed,as well as the static power supply current taking and return plan.It is the first time to propose a traction network plan for the maintenance shed under the dedicated rail return mode that meets the requirements of process maintenance and traction power supply system.It comprehensively summarizes the experience accumulated in the project and provides guidance and reference for similar projects in the future.
