摘　　要 设计目的是完成***车站接触网工程设计，按照工程要求绘制接触网平面设计图和接触网设备装配图。 铁路作为国家重要的基础设施、国民经济的大动脉和大众化的交通工具，具有运能大、能耗省、占地少、污染轻、全天候、高效率等特点，对经济社会发展有着巨大的影响。车站对保证运输工作质量起着决定作用。铁路车站及枢纽的能力是铁路运输能力的主要组成部分。因此，合理规划车站及枢纽总图，具有重要的意义。 设计首先对***车站接触网工程背景、设计内容、设计依据、设计原则及设计目标做了简要叙述，并对设计要完成的主要工作进行了描述。结合***车站实际，设计中充分考虑了当地气象环境和线路情况的条件，进行了线材选择和站场布置，并进行了接触网控制参数、设计时速、风偏移值、最大跨距以及锚段长度的计算，分析了***车站软横跨结构图预制计算Abstract The object is to finish the design of overhead contact system project for Akesu Railway Station, and to draw its graphic draft and device assembly drawing. Railway as a national critical infrastructure, the main artery of the national economy and popular means of transport, has the characteristics of transport capacity, the energy consumption of province, small footprint, light pollution, all-weather, high efficiency and other characteristics, and have a huge impact on the economic and social development. The station plays a decisive role in ensuring the quality of the transportation work. Railway stations and the ability of the hub is a major component of the railway transport capacity. Therefore, the rational planning of the general layout of the station and hub is of great significance. First of all, the project background, design scope, design standards and design purpose of are presented, and main works for the design are sketched. Under the comprehensive consideration of the local meteorological environment and line situation with combination of current situation of Akesu Railway Station, the line material selection and station arrangement are carried out, and some control parameters, design speed, wind deviant and length of anchor-section are calculated, and head span suspension structure draft is analyzed, and then the prefabricated values are calculated, after then the graphic design draft for Akesu Railway Station is drawn according to the following procedures, that is, frame design, anchor-section partitioning, contact line stagger determination, support-post type selection and local typical sup
