摘要当今社会，电力技术的不断发展与完善，推动了经济的发展，加速了工业技术的发展。电力的应用已经遍布人们生活的方方面面。一个优质的供配电系统设计对于建筑物来说十分重要。建工院属于办公楼，人流量较大，需要满足的要求也较多。在设计过程中要尽可能的考虑到每层楼、每间房的具体需求，按照需求进行设计。本次设计的供配电系统，主要涉及强电系统的设计以及相关计算等。主要包括计算负荷量的统计、变压器选择、短路电流计算、无功功率补偿及补偿电容器的选型、高低开关选型、导线选型、变压器的二次整定以及接地防雷保护系统设计等方面。本次设计完成一层接地设计、顶层防雷设计以及每层的平面走线图、一次系统图；完成一层至五层每层配电箱的系统图。根据计算及选型为每图标注相应的导线、开关、控制柜等型号。同时根据系统图，按照行业规范完成了所有的连线以及高低压设备的布置。关键字：建工院，供配电系统，负荷统计，系统图IABSTRACTTheelectricpowertechnologydevelopmentimpelledhumansociety'sprogress,alsohasacceleratedthetechnicaldevelopment.Theelectricpowerapplicationalreadyproliferatedtheaspectswhichthepeoplelived.Highqualitysuppliestheelectricalpowerdistributionsystemdesigntobeextremelyimportantregardingthebuilding.Theconstructionworkcourtyardbelongstotheofficebuilding,thestreamofpeoplequantityisbig,needstosatisfytherequestarealsomany.Inthedesignprocessmustasfaraspossibleconsiderationeachbuilding,eachroomconcretedemand,carryonthedesignaccordingtothedemand.Thisdesignfortheelectricalpowerdistributionsystem,mainlyinvolvesthestrongelectricitysystemthedesignaswellasthecorrelationcomputationandsoon.MainlyIIincludesthecomputationloadthestatistics,theshort-circuitcurrentcomputation,thetransformershaping,thereactivepowercomputationaswellasthecompensation,thehighandlowpressureequipmentchoice,wireaspectsandsoonshaping,transformertwoinstallationsaswellasearthanti-radarprotection.Thisdesigncompletesanearthdesign,thetoplayeranti-radardesignaswellaseachlevelplanewalksthegraph,adiagram;Completesonetofiveeachdistributingboxdiagrams.Accordingtocomputationandshaping，weshouldlabelthecorrespondingwire,switch,controlcubicle.Simultaneouslyactsaccordingtothediagram,hascompletedallsegmentsaswellasthehighandlowpressureequipmentarrangementaccordingtotheprofessionstandard.Keywords:Constructionworkcourtyard,forelectricalIIIpowerdistributionsystemdesign,loadstatistics,diagram.目录摘要...................................IIABSTRACT...............................III目录..................................IV第一章.................................................................绪论11.1选题的目的与意义..............................................11.2国内外发展现状.................................................11.3工程概况及研究方法.........................................21.3.1工程概况...........................................................21.3.2研究方法..........................................................31.4本文的研究内容及安排.....................................3第二章.....................................................统计负荷量42.1概述.....................................................................42.2负荷计算.............................................................42.3电气负荷的计算.................................................5IV2.3.1负荷按需要系数法计算..................................52.3.2负荷按密度计算法计算..................................62.3.3详细负荷计算..................................................72.3.4负荷量统计...
