摘　　要：本文阐述了时速160公里电气化铁路单线隧道内接触网采用旋转全腕臂悬挂时(由于净空受限关节处腕臂采用对侧抬头安装),承力索座安装在两种不同状态的腕臂上,在温度应力发生变化时其工作状态的分析与优劣比较。接触网腕臂支持结构的变化能够引起其零部件的选型及其功能实现程度上的变化。承力索座作为接触网悬挂、固定重要零件对其工作状态的分析,有利于其功能、结构、材质、工艺及环境适应性上的优化处理,并能够使其更好的服务于接触网系统。This article expounds the speed of 160 km of electrification railway catenary in single tunnels using the rotary bracket when suspension （due to limited clearance joints with the eontralateral wrist arm up installation）, carrier cable installed in two different states of wrist arm, changes in temperature stress analysis and the working state of the advantages and disadvantages compared. Catenary bracket support structure changes can cause its components selection and function realization degree of change. Carrier cable as catenary suspension, fixed important parts on the analysis of its working state, is conducive to its function, structure, material, technology and environment adaptability on the optimization of the processing, and be able to make it better serve the catenary system.
