摘 要
接触网技术的研究和设计是高速电气化铁路发展的基础，使接触网始终处于良好工作状态，安全可靠的向电力机车供电，对于保证铁路运输畅通无阻有着重大意义。
本设计是对车站接触网的设计，重点介绍了高速电气化接触网的基本组成和结构特征，如接触线索，支持装置，接触悬挂，定位装置，支柱基础等部分；同时完成了关于站场接触网平面布置图的设计计算，如气象条件与悬挂形式的确定，负载计算，拉出值与锚段选择，跨距确定与校验，支柱负载计算与校验等部分；最后完成了平面图表格栏部分与并对本设计做了最后总结性说明。
本设计绘制出了大沙坪车站接触网的CAD平面布置图与供电平面图。
关键词：站场 接触网 布置图
Abstract
The technology research and design of the catenary is the basis for the development of high-speed electrified railway, so that to make the catenary in good working condition, safe and reliable power supply to electric locomotives, is of great significance to guarantee the rail transport smooth flow.
This design is about the design of the station catenary, focusing on the basic composition and structure of high-speed electrified catenary, such as contact leads, support devices, touch suspension, positioning devices, and other parts of the foundation pillars; simultaneously on the station catenary floorplan design calculations, such as weather conditions and the form of the suspension, load calculation, pull the anchor segment selector value, determine the span calibration, and other pillars of the load calculation and verification part; finally completed the plan forms part of the column and the design and made a final summary description.
This design drawn out of the station Dashaping catenary CAD floor plan and the map for suppling energy.
Key words: Station Catenary Layout
