1、摘要本次毕业设计题目为郡原美村1#楼电气设计，本工程为地上6层的三类低层民用住宅楼。课题的相关设计内容包括建筑电气设计的强电、弱电和消防部分设计。它包括用电负荷计算、电气照明及插座、防雷与接地、可视对讲系统设计、有线电视系统设计、电话系统设计、网络系统设计。本工程为三级供电，采用高低压配电房引来主用电源和备用电源供电，配电电压为380/220V。接地型为TN-C-S系统。每套住宅设置电度表计量用电量，集中安装在底层单元总配电箱。配电方式采用放射式。户内照明采用吸顶座灯，插座分为一般插座、空调插座、卫生间插座、厨房插座、冰箱插座和油烟机插座等。防雷为三类防雷设置避雷
2、设施，接地采用联合基地装置。住宅单元入口处设置访客对讲系统。有线电视系统采用分配分支方式，用户输出口信号电平都为68±4dB，信号由多模光纤引自广播电视局有线电视网。本次设计旨在综合应用及巩固在校期间所学的基本知识和技能，熟悉设计工作基本方法及设计思想，加深对理论知识的理解，为今后的工作打下一定的基础。关键词：配电系统；照明；负荷计算；防雷接地；弱电系统IVAbstractThegraduationdesigntopicisJunYuanBeautifulVillage1#buildingelectricaldesign,thisprojectforthegrou
