河南理工大学万方科技学院毕业设计/论文摘要本设计是针对“ZYA市新建110KV变电站”一次设计的要求，对电力系统及变电所的具体情况进行了分析与说明，对主变压器和主接线进行了设计与选择，并进行了短路电流的计算，根据所求的结果和已知的数据确定了母线、母线引下线、断路器、隔离开关、绝缘子、避雷器等必需的电气设备，且对变电所进行了防雷设计。根据变电所给定的负荷，我们不难对主变进行选择，并用一级和二级负荷对其容量的选择进行校验，根据远景与近景负荷的比较确定一期工程主变的台数。电气主接线的设计是变电站电气设计的主体，在设计中应以任务书为依据，以国家经济建设的方针、政策、技术规定、标准为保证供电可靠、调度灵准绳，结合工程实际情况在活、满足各项技术要求的前提下兼顾运行、维护方便，尽可能的节省投资。导体和电气设备的选择是电气设计的主要内容之一，电力系统中各种电气设备的作用和工作条件不一样，具体选择的方法也不完全相同，但对它们都有一致的要求，电气设备要能可靠的工作，必须按正常工作条件进行选择，并按短路状态来校验热稳定和动稳定。配电装置是根据电气主接线的连接方式，由开关电器、保护和测量电器，母线和必要的辅助设备组建而成的总体装置。以本设计来看110KV宜采用室外形式，35KV和10KV宜采用室内形式。为了预防和限制雷电的危害性，变电站中还应采用防雷措施和防雷保护装置。关键词：断路器隔离开关配电装置避雷器I河南理工大学万方科技学院毕业设计/论文AbstractII河南理工大学万方科技学院毕业设计/论文Thisdesignaimsattherequestwhich"WHthecitynewlybuilt110KVtransformersubstation"timedesigns,hascarriedontheanalysisandtheexplanationtotheelectricalpowersystemandthetransformersubstationspecialdetails,hascarriedonthedesignandthechoicetothemaintransformerandthehostwiring,andhascarriedontheshort-circuitcurrentcomputation,accordingtoresultandknowndatadeterminationgenerator,generatordownload,circuitbreaker,isolator,insulator,andsoonwhichasksessentialelectricalequipment,alsohascarriedontheanti-radardesigntothetransformersubstation.Accordingtothegivenloadsubstation,wenotdifficultlychangetothehostcarryonthechoice,andcarriesontheverificationwithlevelofandtwolevelofloadstoitscapacitychoice,changestheTaiwannumberaccordingtotheprospectandthecloseviewloadquitedefiniteissueofprojecthost.Theelectricalhostwiringdesignisthetransformersubstationelectricitydesignmainbody,inthedesignshouldtaketheprojectdescriptionasthebasis,takethenationaleconomicconstructionpolicy,thepolicy,thetechnicalstipulation,thestandardasthecriterion,theunionprojectactualsituationintheguaranteepowersupplyreliable,thedispatchernimble,satisfieseachspecificationunderthepremisetogivedualattentiontothemovement,themaintenanceisconvenient,asfaraspossiblesavestheinvestment.Theconductorandtheelectricalequipmentchoiceisoneofelectricaldesignmaincontents,intheelectricalpowersystemeachkindofelectricalequipmentfunctionandtheworkingconditionaredissimilar,concretechoicemethodquitesamenotlessthan,butallhastheunanimousrequesttothem,theelectricalequipmentmustbeablethereliablework,mustcarryonthechoiceaccordingtotheregularservicecondition,andaccordingtoshort-circuitstheconditiontoverifythethermallystableandtomovestably.Thepowerdistributionequipmentisaccordingtotheelectricalhostwiringconnectionway,bytheswitchelectricappliance,theprotectionandthesurveyelectricappliance,thegeneratorandtheessentialsupportingfacilitysetsuptheoverallinstallmentwhichbutbecomes.Bythisdesignlooked110KVsuitablyusesoutdoorform,III河南理工大学万方科技学院毕业设计/论文35KVand10KVsuitablyusesintheroomtheform.Inordertopreventwithth...
