摘　　要：由于城市轨道交通与市郊铁路供电制式不同,不能在同一接触网上并存,且接触网锚段有完整性、导线有不可分割性要求,城市轨道交通与市郊铁路连通必须设置衔接段。分析比较城市轨道交通和市郊铁路接触网的差异,详细论述衔接段牵引供电制式、受流方式、架空接触网导线高度、设备限界、回流网、开关设备的设置。指出如果付诸实施还需要从政策层面解决管理、运营和维护的协同配合。Due to the difference in power supply system between urban rail transit and suburban railway,they cannot run under the same contact network at the same time.In addition,the integrity of catenary anchor section and the indi⁃visibility of conductors require that the connection between urban rail transit and suburban railway must be set up.This paper analyzes and compares the difference of catenary in between,and discusses in detail the traction power supply system,current receiving mode,overhead catenary wire height,equipment limit,backflow network and the set⁃ting of switching equipment in connection section.It is pointed out that if implemented,the coordination of manage⁃ment,operation and maintenance should also be addressed from the policy level.
