.. 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 Abstract The graduation project entitled Lishui Garden Building C, electrical design, this floor is a staircase 4, a total of 18 layers. This works for three loads, power supplies are drawn from district substation, voltage level for the 380V/220V, this works with the trunk type, power supply power supply substations in the region cited a young age, household electricity load is 10KW. Design elements include electric and electronic design two parts. Among them, the strong electrical design including: power distribution system design, lighting design, socket system design and the design of lightning protection and grounding system; weak design include: cable system design, fire protection system design. Lighting design by environmental and efficiency standards, including the illumination calculation, the choice of lamps, lighting, trunk, plug wires and wire cross-sectional area of the choice of laying mode. Socket system according to the standard high-end residential design. Socket and lighting circuits with different routing slip back to power, the general socket mounting height of 0.3 meters, air-conditioning outlet height from 1.8 meters above the ground, should be installed in damp and humid areas, splash-proof type power outlet. Grounding system using TN-C-S system. Lightning protection system installed in the roof with lightning rods and lightning combination Jieshan Qi. Distribution of branches by way of cable television system, the user output s
