简单链型悬挂AT方式接触网设计DesignofOverheadContactSysteminSingleCatenarySystemwithATWay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。关键词：电气化铁路接触网设计简单链型悬挂AT方式AbstractWithitsadvantagesofstrongertransportcapacity,loweroperatingcosts,lessenergyconsumption,smallerenvironmentalpollutionandsoon,theelectrifiedrailwayisuniversallyconcernedandhasbecametherailwaydevelopmentorientation.Theoverheadcontactsystem,asoneofthemostimportantcomponentsintheelectrifiedrailway,itsstatehasbeentakinggreateffectsonthesafeoperatingoftheelectrifiedrailway.Therefore,reasonabledesigncanimprovereliabilityofthesystem,toensurethattheelectrifiedrailwaywouldoperatesafely.Designofcatenaryespeciallyforhigh-speedconsistsofalotofdesigncalculations,drawings,checkingandsoon.Toreducetheworkofdesignersofcatenary,shortenthetimeofdesigncycle,improvedesignquality,ensuresafetyandreliabilityoftheelectrifiedrailwayoperation,usingcomputer-aideddesignisverynecessary.ThisdesignistheuseofAutoCADasadrawingtool,basedonthecorrespondingcalculations,designmanualandmeteorologicalconditionsfortheassociatedsectiondesignabouttheselectionofthespan,thedropper,thecompensationdevice,theoverlapspan,themastandsoon.Keywords:electrifiedrailwaydesignoftheoverheadcontactsystemsinglecatenarysystemautotransformerway目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc359341232"第1章绪论PAGEREF_Toc359341232\h1HYPERLINK\l"_Toc359341233"1.1课题研究的目的意义PAGEREF_Toc359341233\h1HYPERLINK\l"_Toc359341234"1.2国内外发展现状PAGEREF_Toc359341234\h1HYPERLINK\l"_Toc359341235"1.3设计的目的及主要任务PAGEREF_Toc359341235\h1HYPERLINK\l"_Toc359341236"第2章牵引网简介PAGEREF_Toc359341236\h3HYPERLINK\l"_Toc359341237"2.1牵引网供电方式PAGEREF_Toc3593
