文档介绍：简单链型悬挂AT方式接触网设计
Design of Overhead Contact System in Single Catenary System with AT Way
摘要
电气化铁路因其运输能力强、运营成本低、能源消耗少和环境污染小等优点,受到世界各国的普遍重视,成为了当今铁路的发展方向。而接触网作为电气化铁路的重要组成部分,其状态的优劣直接影响到电气化铁路的运行安全。因此,合理的接触网设计,能够提高接触网系统的可靠性,保证铁路生产的正常运行。
接触网设计特别是高速接触网设计过程包含了大量的设计计算、绘图、校验等工作。为了减少接触网设计人员的工作负担,缩短设计周期,提高设计质量,保证电气化铁路运行的安全性和可靠性,使用计算机辅助设计是非常必要的。本次设计就是采用AutoCAD为制图工具,依据相应的计算结果、设计手册和气象条件等对区间进行相关的跨距的选择,吊弦的设计,补偿装置的选取,锚段关节的选用,支柱布置和类型选取等。

Abstract
With its advantages of stronger transport capacity, lower operating costs, less energy consumption, smaller environmental pollution and so on, the electrified railway is universally concerned and has became the railway development orientation. The overhead contact system, as one of the most ponents in the electrified railway, its state has been taking great effects on the safe operating of the electrified railway. Therefore, reasonable design can improve reliability of the system, to ensure that the electrified railway would operate safely.
Design of catenary especially for high-speed consists of a lot of design calculations, drawings, checking and so reduce the work of designers of catenary, shorten the time of design cycle, improve design quality,ensure safety and reliability of
the electrified railway operation, puter-aided design is very necessary. This design is the use of AutoCAD as a drawing tool, based on the corresponding calculations, design manual and meteorological conditions for the associated section design about the selection of the span, the dropper, pensation device , the overlap span,the mast and so on.
Key words: electrified railway design of the overhead contact system single catenary system autotransformer way
