住宅小区10Kv变电所及配电系统设计摘要随着社会经济的发展，国民生产力的不断提高，人们对于居住条件的要求也越来越高。电能的分配和使用在人们生活中的地位日益提高。如何将电能从发电厂输送并转化为居民所用电压，是需要研究的重要课题。本次主要设计内容为小区10Kv变电所以及配电系统设计，实现了降压并分配电能到用户的功能。该小区面积大，考虑到供电半径以及负荷容量问题，共设计了1个主变电所和3个分变电所。通过负荷计算、额定电流计算，依据相关规范对主变压器、母线、断路器、隔离开关、电流互感器、电压互感器、补偿器、避雷器等进行了选择。负荷计算采用单位面积法，依据建筑不同的用电类别、用途，在经验表格中查取相应的单位面积用电指标，S=用电指标*建筑面积。电气设备主要根据额定电流进行选择。根据对负荷的分级和计算，两回路10Kv进线，比较几种接线方式后选定高压侧为单母线分段接线，低压侧依据对不同的类型负荷用电(小区包括居民用电、商业用电和soho用电)，采用了单母分段和单母线接线相结合的方式。并绘制了图纸。该设计实现了小区电能的转化和分配问题，变电所选址、负荷分配，主接线设计、电气设备选择合理，理论上满足了用户对于电能的需求。关键词：变电所，配电系统，主接线，电气设备10KvSubstationinZhonghaiLianyuResidentialAreaAnddistributionsystemdesignAbstractWiththedevelopmentofsocialeconomyandthecontinuousimprovementofnationalproductivity,people'srequirementsforlivingconditionsaregettinghigherandhigher.Thedistributionanduseofelectricenergyareplayinganincreasinglyimportantroleinpeople'slives.Howtotransferelectricenergyfrompowerplanttoresidentialvoltageisanimportantsubjecttobestudied.Themaincontentofthisdesignisthedesignof10Kvsubstationanddistributionsysteminresidentialarea,whichrealizesthefunctionofreducingvoltageanddistributingenergytousers.Consideringthepowersupplyradiusandloadcapacity,amainsubstationandthreesubstationsaredesigned.Throughloadcalculationandratedcurrentcalculation,themaintransformer,bus,circuitbreaker,disconnector,currenttransformer,voltagetransformer,compensatorandlightningarresterareselectedaccordingtorelevantspecifications.Theunitareamethodisusedtocalculatetheload.Accordingtothedifferenttypesandusesofbuildingpowerconsumption,thecorrespondingunitareapowerconsumptionindexisfoundintheexperiencetable.S=powerconsumptionindex*buildingarea.Electricalequipmentismainlyselectedaccordingtoratedcurrent.Accordingtotheclassificationandcalculationofload,aftercomparingseveralconnectionmodes,thehigh-voltagesideisselectedassingle-bussectionconnection.Thelow-voltagesideiscombinedwithsingle-bussectionandsingle-busconnectionaccordingtodifferenttypesofload(residentialpower,commercialpowerandSOHOpower).Anddrawingsweredrawn.Thedesignrealizestheconversionanddistributionofpowerinresidentialarea,andmeetstheuser'sdemandforpowerintheory.Keywords:Substation，Powerdistributionsystem，Mainwiring，Electricalequipment目录摘要................................................................IAbstract............................................................II第1章绪论........................................................11.1引言.....................................................................................................11.2研究目的和意义.....................................................................................11.3国内外发展概况.....................................................................................11.3毕业设计内容........................................................................................21.3.1原始...
