兰州交通大学毕业设计（论文）--I摘要建筑电气是以电能、电气设备和电气技术为手段，创造、维持与改善室内外空间的电、光、热、声环境的一门重要学科，它在人们的日常生活中发挥着极大的作用。本次设计完成了兰州交通大学四号实验楼电气设计。设计内容主要有楼层的照度计算、灯具的选择、开关的选择、负荷计算、插座的选择、导线的选择、电缆的选择、应急照明的设计、配电箱的选择等。在照明设计中，照度计算采用工程中常用的“单位容量法”。普通照明设备选用了嵌入式荧光灯，在此基础上完成了电气照明的平面布置图，并根据需要对该建筑的应急照明给出了具体的设计。为每个实验室安装了单相插座，并完成了插座回路的布置。配电设计中，负荷计算采用的是“需用系数法”。通过负荷计算，完成了整个实验楼的配电系统设计，并且在各层楼都安装了应急照明灯。.本设计采用“天正电气8.0”绘图软件绘制了电气照明平面图、配电系统图和电气说明图。关键词：建筑电气；照明；照度计算；负荷计算兰州交通大学毕业设计（论文）--IIAbstractBuildingelectricityisbasedonelectricpower,electricityequipmentsandelectricitytechnique,andalsoasubjectforcreating,maintainingandimprovinglight,heat,voice,indoorsandoutdoorsenvironment.Itplaysagreatroleinpeople'sdailylife.ThepapercompletestheelectricallightingdesignoftheforthexperimentalbuildingofLanzhoujiaotonguniversity.Themaindesignelementsincludeilluminationcalculationoffloor,choiceoflampsandswitching,loadcalculation,socketoption,wirechoice,andchoice,emergencylightingdesign,choiceofpowerdistributionbox,mineoflaboratorybuilding,andsoon.Inthelightingdesign,illuminationcalculationusestheunitsofcapacity”whichiscommonlyusedintheproject.Generallightingequipmentchoosesthetopembeddedfluorescentlight.Onthebasis,thelayoutplanoftheelectricallightingiscompleted,andthespecificdesignofemergencylightingisconductedinaccordancewiththeneedsofconstruction.Single-phasepoweroutletsareinstalledforeachlaboratory,andthecircuitlayoutofthesocketiscompleted.Inthedistributiondesign,loadcalculationisbasedonrequiredcoefficientmethod.”Thepowerdistributionsystemoftheentirefloorisdesignedthroughtheloadcalculation,andthedistributionscreenisatroominthefirstfloor,whichnotonlydistributestheelectricpowertovariouslightingdistributionboxes,butalsosupplieselectricityalonetotheliftonthetopfloor.Finally,theoverallmineofthelaboratorybuildingisdesigned.Inthedesign,theelectriclightingfloorplan,distributionsystemplanandelectricalexplanationplanaredrawnbyTianzhengElectric8.0mappingsoftware.Keywords:BuildingElectricity，Illumination，IlluminationCalculation，LoadCalculation兰州交通大学毕业设计（论文）--III目录摘要.....................................................................................................................................IAbstract.....................................................................................................................................II1绪论........................................................................................................................................11.1课题背景和意义.........................................................................................................11.2课题的内容与目标.....................................................................................................11.3设计原则.....................................................................................................................21.4设计依据.....................................................................................................................22照明系统设计........................................................................................................................32.1照明要求.....................................................................................................................32.2照明方式和照明种类.................................................................................................32.2.1照明方式分类..................................................................................................32.2.2照明种类..........................................................................................................42.3光源和灯具.................................................................................................................42.3.1光源..................................................................................................................42.3.2灯具..................................................................................................................42.4灯具的布置.................................................................................................................52.5照明质量和照度标准.................................................................................................62.5.1照明质量..........................................................................................................62.5.2照度标准..........................................................................................................72.6照度计算.....................................................................................................................72.7本工程照度计算内容.................................................................................................92.7.1实验室照度计算..............................................................................................92.7.2走廊的照度计算..............................................................................................92.7.3研究室照度的计算........................................................................................142.8插座和开关的布置...................................................................................................162.8.1插
