摘　　要：接触网是轨道交通供电牵引系统中直接向列车授电的设备,其牵引载流能力的提升也是供电系统扩容改造的一个重要组成部分。柔性接触网在低净空隧道的安装形式,从扩容改造方案的角度上来说存在着一定的难度和风险。结合上海轨道交通2号线接触网大修改造工程,分析和研究了在低净空隧道的条件下增加柔性接触网馈线的设计方案。The catenary is an important part of the traction power supply system of rail transit,and the expansion of traction load capacity is also an important part of the expansion and transformation of power supply system.However,the installation of flexible catenary in a tunnel with low clearance has certain difficulties and risks from the perspective of expansion and transformation scheme.Based on the catenary renovation project of Shanghai Rail Transit Line 2,the design scheme of adding flexible catenary feeder line in a tunnel with low clearance is analyzed and studied.
