摘　　要：市域(郊)铁路分为地下和地上两种安装方式,相应的接触网也需满足地下和地上的安装。通过分析接触网牵引供电制式及授流方式,结合国内运营线路的应用情况,确定时速160 km市域(郊)铁路接触网宜采用交流制式25 kV和架空方式授流。由于国内时速160 km市域(郊)铁路很少,在介绍地下段的接触网悬挂方式后,详细分析了地下段刚性悬挂接触网拉出值及平面布置、跨距和硬点等主要方面对弓网动力特性的影响,并分别提出了适应于高速市域(郊)地下区段的接触网措施。通过对地上段柔性接触网拉出值和刚柔过渡等影响弓网动力特性的问题进行论述,提出了对应优化方案。Suburban railway is divided into under ground and above ground installation methods,the corresponding catenary needs to meet the requirements of under ground and above ground installation.By analyzing the traction power supply system and current collection mode of OCS,and combined with the application of domestic suburban railway,it is determined that AC 25 kV system and overhead current collection mode should be adopted for the OCS of 160 km/h suburban railway.Since there are few 160 km/h suburban railways in China,after introducing the suspension mode of OCS in under ground section,this paper analyzes in detail the influence of the pull-out value,plane layout,span and hard point of rigid suspension OCS in under ground section on the dynamic characteristics of pantograph and catenary,and puts forward the OCS measures suitable for high-speed suburban under ground section.Based on the discussion of the pull-out value and rigid flexible transition of the flexible catenary in the above ground section,the corresponding optimization scheme is put forward.
