摘要随着现代城市建筑的发展以及人民生活水平的不断提高,越来越多的智能小区不断涌现,这些小区呈现出功能复杂、技术先进的特征,所以对小区建筑的供配电系统的设计也提出了更高的要求。在建筑供配电系统的设计进程中,建筑电气的根本是要做到建筑必需的各项功能和安全需求的实现,随着人们对节约能源、保护环境和降本增效等问题的关注,建筑电气节能设计也日益被重视,并且成为建筑电气设计的主要内容。节能作为国民经济的一项长远战略方针,怎样实现“节电能、降能耗”的目标,是每位电气设计人员需要认真考虑的问题。因此,人们所关注的不仅仅是建筑施工的质量,更关心的是建筑的消防问题,本文针对目前建筑供配电系统设计中的难点问题,结合生活实际,以金域名都小区为例,提出了相关建议。关键词:金域名都;供配电系统;设计AbstractWiththedevelopmentofmoderncityconstructionandtheimprovementofpeople'slivingstandard,intelligentcommunitymoreandmorecontinuetoemerge,thesecellsshowedacomplexfunction,technologyadvancedfeatures,sothedesignofpowersupplyanddistributionsystemforresidentialbuildingisalsoputforwardhigherrequirements.Inthedesignprocessofpowersupplyanddistributionsystemarchitecture,basicelectricalbuildingistoachievetheconstructionmustbethefunctionsandsecurityneeds,aspeoplefallthissynergismonissuessuchasenergysaving,Protectenvironmentandattention,electricalenergysavingdesignofbuildingsarealsogainingmoreattention,andbecomesthemaincontentofbuildingelectricaldesign.Energysavingasalong-termstrategyofnationaleconomy,howtorealizethe"savingenergy,reducingenergyconsumption",iseveryelectricaldesignersneedtoseriouslyconsidertheissue.Therefore,peoplepayattentiontonotonlythequalityofbuildingconstruction,aremoreconcernedaboutthefireprotectionofbuilding,thispaperaimedatthedifficultissuesinthedesignofpowersupplyanddistributionsystemsinbuildings,combinedwiththeactuallife,tojymdareaasanexample,putsforwardrelatedsuggestions.Keywords:Jymd;Powerdistributionsystem;Design目录一、绪论..................................................11.1选题背景及意义.....................................11.2建筑电气技术的发展现状及趋势.......................11.3金域名都小区工程概况...............................11.4设计的主要内容.....................................21.4.110/0.4kV供配电系统设计.......................21.4.2火灾自动报警与消防联动系统设计................21.4.3综合防雷系统设计..............................2二、10/0.4KV变配电系统设计...............................22.1负荷计算...........................................22.2短路电流的计算.....................................32.3变压器的选择.......................................32.4配电系统的设计.....................................42.510KV变配电系统继电保护的设计......................42.6备用电源的设计.....................................52.7小区配电自动化的设计...............................5三、消防系统的设计........................................63.1供电控制的设计.....................................63.2线路敷设的设计.....................................63.3双末端自切设计.....................................73.4消防保护设计.......................................73.4.1自动灭火设计..................................73.4.2排烟与防烟设计................................7四、综合防雷的设计........................................74.1现代防雷设计的新重点...............................74.2工程防雷总体方案...................................84.3外部防雷设计.......................................84.4内部防雷设计.....
