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。 关键词：电气化铁路 接触网设计 简单链型悬挂 AT方式 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 important components 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 on.To 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, using computer-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, the compensation device , the overlap span,the mast and so on.
