某办公大楼建筑电气设计

I摘要随着经济建设的发展，中国当前城市建设发展迅速，其规模之大、范围之广，均是空前的。由于建筑技术和信息技术的相互渗透结合和迅猛发展，在20世纪80年代中期产生了新的建筑类型——智能建筑。本论文主要阐述了某办公楼各系统电气设计的设计依据、原则和方法及设计选择的结论。本论文共包括六章内容，前四章主要包括强电部分设计；第五、六章主要包括弱电部分及消防设计。强电部分主要内容包括：低压配电系统、照明系统及防雷接地系统的设计，其中包括负荷计算、照度计算等。弱电部分主要内容包括：有线电视、公共广播系统、闭路电视监控及综合布线系统的设计。消防部分主要报警系统、联动系统的设计等。本办公楼电气设计为毕业设计，其目的是通过设计实践，综合运用所学知识，理论联系实际，锻炼独立分析和解决建筑电气设计问题的能力，为未来的工作奠定坚实的基础。关键词建筑电气设计，照度，有线电视，闭路电视监控IIAbstractWiththedevelopmentofeconomicconstruction,theconstructionanddevelopmentofpresentcityofChinaarefast,itsscalebig,rangeiswide,isunprecedented.Techniquepermeatethecombinationmutuallywiththeinformationbecauseofthebuildingtechniquewithfastandfiercedevelopmentofbuildingelectricitytechnology,in1980’sagetheperiodthenewbuildingtype-intelligentbuildingsturnedout.Thisthesismainlyexplainstheelectricaldesignbasis,principle,methodsandtheconclusionofthedesignchoiceineachsysteminthedesignofcertainofficebuilding.ThethesisincludessixChapters.previousfourChaptersaremostlyaboutthedesignoftheforcefulelectricpowerPart；Chapter5and6aremostlyaboutthedesignofthelightcurrentandfire-fighting.Thepartoftheforcefulelectricpowermainlyincluding:thedistributionsystemofthelowvoltage,lightingsystemandroundingforlighteningsystematicalcompose，amongothersincludeloadcalculation,illuminationcalculation.Thepartofthelightcurrentmainlyincluding:CATV,PublicBroadcastingSystem,ClosedCircuitMonitoringTVandPremisesDistributionSystemandsoon.Thepartofthefire-fightingmainlyincluding:thedesignofthewarningsystemandlinkedsystemetc.Thiselectricaldesignoftheofficebuildingisagraduationdesign，Thepurposeofthisdesignistogiveusachanceofsyntheticallyusageoftheknowledgewehavelearned.Besides,itcantrainourabilitytoanalyzeandsolvepracticalproblemsinConstructelectricityindependentlysothatthetheoryisconnectedwithpracticeandasolidbaseismadeinfavoroffuturework.KeyWordsBuildingElectricalDesign,Illumination，ClosedCircuitMonitoringTVIII目录摘要............................................................................................................................IAbstract......................................................................................................................II目录...........................................................................................................................III1前言...........................................................................................................................11.1建筑电气概况.......................................................................................................................11.2工程设计概况.......................................................................................................................11.3设计依据...............................................................................................................................11.4设计范围...............................................................................................................................11.5供配电设计.........................................................................................................................21.6低压配电系统设计................................................................................................................21.7照明系统设计.......................................................................................................................21.8防雷接地系统设计...............................................................................................................31.9火灾自动报警与联动控制系统设计....................................................................................31.10弱电系统设计.....................................................................................................................42配电系统设计.........................................................................................................52.1负荷等级及供电要求...........................................................................................................52.1.1负荷等级分类...............................................................................................................52.1.2供电要求.......................................................................................................................52.2负荷计算...............................................................................................................................62.3导线选择...............................................................................................................................72.3.1电缆选择原则...............................................................................................................72.3.2选择结果.......................................................................................................................82.3.3断路器的选择原则.......................................................................................................82.4配电方式...............................................................................................................................93照明系统设计............................................................................
