毕业论文--小区建筑电气设计.doc

摘要
本次毕业设计题目是小区建筑电气设计,本工程为地上20层,地下一层,其中一层为商铺,二到四层为办公楼,五到二十层为住宅楼。工程用电有一级负荷和三级负荷,供电电源引自小区变电站,电源电压为380V/220V。依据相关规范对工程的照明系统、插座系统、供配电系统、防雷接地系统、有线电视系统及电话通信系统进行设计。
照明系统设计包括照度计算、照明干线、导线截面积的选择以及导线的敷设方式。插座系统设计包括插座布置、插座选择以及插座的正确安装高度,插座回路与照明回路由不同支路供电,空调插座为单独回路。建筑物为第三类防雷建筑,防雷系统设计是在屋面上装设避雷针与避雷带相结合的接闪器,接地形式采用TN—C—S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为68±4dB,信号引自市内有线电视网。电话和网络系统线路敷设在同一根管道内。

Abstract
This graduation design project is a sunny plot # 1 story building electrical design, this project is 20 floors above ground, ground floor, one level for shops, two to four-story office building, five to 20 floors for residential buildings. Project electricity there is a load and three load power supply cited in the district substation, the power supply voltage 380V/220V. In accordance with the relevant norms on lighting systems, outlet systems for power distribution systems, lightning protection and grounding systems, cable television system and munication system lighting system design including illumination calculations, lighting Link,the choice of conductor cross-sectional area and wire laying method. The socket system design, including socket layout, socket selection and correct installation height, the outlet circuit and lighting back routing slip-powered, air-conditioning outlet socket for a separate circuit. Building for the third class of mine buildings, the design of lightning protection system is provided with lightning and lightning on the roof with bination of air-termination system, grounded in the form of TN-C-S television system distribution branch, user output signal level of 68 ± 4dB signal to quote from the city's cable work. Line laying of telephone work systems with a pipeline.
