1、摘要本次毕业设计题目为丽水花园C座楼电气设计,本楼为一梯四户,一共有十八层。本工程为三级负荷,供电电源均引自小区变电站,电压等级为380V/220V,本工程采用树干式,供电供电电源引自小区内变电站,用电负荷为每户10KW。设计内容包括强电和弱电设计两个部分。其中,强电设计包括:配电系统的设计、照明系统设计、插座系统设计及防雷与接地系统的设计;弱电设计包括:有线电视系统的设计、消防系统设计。照明系统按环保节能标准设计,其中包括照度计算、灯具的选择、照明干线、插座导线截面积的选择以及导线的敷设方式。插座系
2、统按高档住宅标准设计。插座回路与照明回路由不同支路供电,一般插座安装高度为0.3米,空调插座距地高度为1.8米以上,潮湿场所应装设防潮、防溅型的插座接地系统采用TN—C—S系统。。防雷系统设计在屋面上装设避雷针与避雷带相结合的接闪器。有线电视系统采用分配分支方式,用户输出口信号电平为68±4dB。满足用户要求。建筑物为第三类防雷建筑。在本次毕业设计当中共绘制了19张图纸,除一张手绘图外全部由CAD绘制。关键词:照明设计;有线电视设计;供配电系统设计;消防系统设计42AbstractThegraduat
