摘　　要：国内已有城市轨道交通工程采用架空接触网供电、专用轨回流解决杂散电流泄漏问题,但目前尚无接触轨供电制式下的专用轨回流应用案例。基于接触轨供电制式,提出4种专用轨回流方案,从对区间设备的影响、车辆回流、线路网络化运营、供电系统继电保护、安全性和成本效益等方面,通过定量、定性的方法分别对4种专用轨回流方案进行分析评价,论述各个方案的可行性和优缺点。最终提出推荐的基于接触轨供电制式下的专用轨回流方案,并总结专用轨回流对其他专业的影响。The urban rail transit projects in China have adopted overhead contact system power supply and dedicated rail return current scheme to solve the problem of stray current leakage.However,there are currently no applications of dedicated rail return under contact rail power supply systems in China.This article proposes four dedicated rail return current schemes based on the contact rail power supply systems.It analyzes and evaluates these four schemes through quantitative and qualitative methods,considering aspects such as equipment impact,vehicle current return,networked operation of lines,power supply system protection,safety,and cost-effectiveness.It discusses the feasibility,advantages,and disadvantages of each scheme,and ultimately recommends a dedicated rail return scheme based on the contact rail power supply system.Finally,it proposes a recommended dedicated rail return scheme based on the contact rail power supply system,and summarizes the impact of dedicated rail return on other disciplines.
