摘　　要：分析了城市轨道交通与干线铁路2个系统的接触网组成,总结了2个系统在牵引供电制式、悬挂方式、接触线高度、设备限界、回流网、开关设备、轨道车辆高压电器设备等方面的差异。根据城市轨道交通与干线铁路所采用的授流方式,提出了在二者的衔接段采用直流架空接触网和交流架空接触网衔接、直流接触轨与交流架空接触网衔接2种设计方案。该研究已在试验线.上得以成功应用,实现了在1条走行轨上同时开行城市轨道交通列车和干线铁路系统机车的接触网设计。The composition of OCS in urban rail transit system and trunk railway line system is analyzed,and the differences between the two systems in aspects including traction power supply mode,suspension mode,contact wire height,clearance requirements,return system,isolation switch,locomotive high-voltage electrical equipment are summarized.Considering the two current collection modes adopted by urban rail transit and trunk railway line,two design schem are proposed.One is connection between DC overhead catenary and AC overhead catenary,and the other is connection between DC conductor rail and AC overhead catenary.The research has been successfully applied on test line,and the OCS design of urban rail transit train and trunk railway line system locomotive running on one track at the same time has been realized.
