湖南妾道职业技兼学院学生毕业设计(论文)摘要根据全国铁路规划,我国计划2020年建成1.8万公里高速铁路,随着高速铁路的迅速发展,牵引供电系统运行与维护己经成为电气化铁路的重要环节。本文介绍了牵引供电系统运行与维护,又以接触网和变电所谓重点,对牵引供电设备的结构,类型,工作原理加以分析。包括变电所的1次回路,2次回路,运营管理,高压设备的日常维护;接触网的工区设备与结构,以及天窗作业和防护。以此对牵引供电系统进行分析,来掌握牵引变电系统的运行状态和维护。关键词:供电系统;接触网;变电所;天窗作业IThisdocumentisproducedbytrialversionofPrint2Flash.Visitwww.print2flash.comformoreinformation湖南妾道职业技兼学院学生毕业设计(论文)ABSTRACTAccordingtothenationalrailwayplanning,planstohave2020kmhigh-speedrailwaywasbuiltin2020inChina,withtherapiddevelopmentofhigh-speedrailway,thetractionpowersupplysystemrunningandmaintenancehasbecomeanimportantpartoftheelectrifiedrailw叫.Thisarticleintroducesthetractionpowersupplysystemoperationandmaintenance,andtocontactlineandsubstationso-calledfbcus,thestructureoftractionpowersupplyequipment,typeandworkingprincipleanalysis.Includingsubstationoneloop,twoloop,operationmanagement,thehighvoltageequipmentdailymaintenance;Catenaiyworkareaoftheequipmentandstructures,andskylightoperationandprotection.Toanalyzethetractionpowersupplysystem,controltherunningstatusofthetractionsubstationsystemandmaintenance.Keywords:substationsystemoperation.Catenary,substation.SkyliaghljobIIThisdocumentisproducedbytrialversionofPrint2Flash.Visitwww.print2flash.comformoreinformation湖南妾道职业技兼学院学生毕业设计(论文)目录摘要............................................................IABSTRACT.................................................................II第1章绪论.....................................................11.1电气化铁路的发展.......................................................11.2本课题的意义和工作重点................................................1第二章牵引供电系统..............................................32.1牵引供电系统简介......................................................32.1.1电流制的发展.....................................................32.2电气化铁路的组成......................................................42.3电气化铁路的供电方式..................................................12.3.1电力系统对牵引变电所的供电方式.................................72.3.2牵引变电所对接触网的供电方式..........................
