区间接触网平面设计

兰州交通大学毕业设计（论文）-I-摘要随着社会经济的发展,我国正在积极推进高速电气化铁路建设大面积、大幅度的提高现有电气化铁路的运行质量，接触网是电气化铁路的子项目,接触网技术的研究和设计是高速电气化铁路发展的基础。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。本设计在概述接触网基本组成的基础上，以高速电气化铁路接触网的基本原理为核心，论述了高速电气化铁路接触网的设计流程和结构特征，并给出了接触网平面设计的技术原则，对其设计过程进行了详细地说明。并系统的阐述了高速电气化铁路接触网的支持装置、结构特征、供电方式等，并着重论述了高速接触网的设计原理及设计内容。本设计依照接触网的设计规范，确定了设计中所必需的各种技术参数，完成由水定至霍尔果斯区间接触网的平面设计，确定高速接触网悬挂模式，根据气象条件，进行设计计算，选取相关主要设备、材料，进行经济技术比较，对接触网进行调整，并应用CAD绘制水定至霍尔果斯区间的接触网的平面设计图。关键词：电气化铁路；接触网；平面设计；结构特征兰州交通大学毕业设计（论文）-II-AbstractWiththedevelopmentofsocialeconomy,ourcountryisactivelypromotingtheconstructionofhighspeedelectrifiedrailway,greatlyimprovingthequalityofexistingelectrifiedrailway,overheadlinesystemisasubprojectofelectrifiedrailway,theresearchanddesignofoverheadlinetechnologyisthebasisforthedevelopmentofhighspeedelectrifiedrailway.TheReasonabledesignofoverheadlinesystemcanimprovethereliabilityofoverheadlinesystem,ensurethenormaloperationoftheoverheadlinesystem.Basedontheintroductionofthebasiccontentsofoverheadlinesystem,thisthesiswasaccordingtothefundamentaltechnicaltheoriesofoverheadlinesysteminhigh-speedrailway,anddiscussesthedesignprocessandstructuralcharacteristicsofthehigh-speedelectrifiedrailwaycontactsystems,providesthetechnologicalprinciplesforthegraphicdesignoftheoverheadlinesystem,andexpatiatesitsdesignprocedure.Bsides,thisthesissystematicallyelaboratesthesupportingequipments,structurefeaturesandpowerwayofhigh-speedoverheadlinesystem,emphasizesontheprincipleandcontentsofdesign.Thisdesignwasaccordingtothedesignspecificationsofoverheadlinesystem,determinethevarioustechnicalparametersthatrequiredindesign,determinetheoverheadlinesystemsuspensionmodel,accordingtothemeteorologicalconditions,calculationthedateandselectedthemajorequipmentandmaterials,besidesmadeeconomicandtechnicalcomparisonanddotheadjustmentsofoverheadlinesystem,atlast,thegraphicdesignoftheoverheadlinesystembetweenShuidingandHuoerguosiwasdrawnbyCADsoftware.KeyWords:Electrifiedrailway,Overheadline,Theplanedesign,Structuralfeatures兰州交通大学毕业设计（论文）-III-目录摘要.....................................................................................................................................IAbstract......................................................................................................................................II目录..................................................................................................................................III1绪论........................................................................................................................................11.1工程背景....................................................................................................................11.2设计范围....................................................................................................................11.3设计依据....................................................................................................................11.4设计目标....................................................................................................................11.5本设计的主要工作....................................................................................................22气象资料................................................................................................................................32.1接触网设计中需要的气象资料................................................................................32.2我国气象区的划分....................................................................................................33设备选择及设计计算............................................................................................................53.1主要设备选用............................................................................................................53.2接触悬挂类型及相关参数的选择............................................................................63.3负载计算....................................................................................................................73.4跨距长度计算............................................................................................................93.5锚段长度计算..........................................................................................................114绘制水定至霍尔果斯区间接触网平面图..........................................................................154.1放图..........................................................................................................................154.2布置支柱..................................................................................................................154.3划分锚段..................................................................................................................154.4确定拉出值..............................................................................................................154.5确定支柱类型..........................................................................................................164.6表格栏及相关说明.................................................................................
