办公楼供配电系统设计.doc

摘 要 本设计的主要内容包括：办公楼供配电总体方案的确定；照度计算；电光源的选择；照明灯具选择与布置；负荷计算；电气设备的选择；电缆导线的选择；防雷保护及接地设计；电气工程概预算等。 在满足办公楼改扩建部分日用电负荷及照明的要求基础上，围绕节能、绿化、美观等因素进行综合建筑电气设计。供配电系统设计采用TN－C－SAbstract This design’s primary content includes: Determination of power distribution; Illumination computation; Choice of electric light source; Arrangement of lamps and lanterns; Load computation; Choice of electrical equipment; Choice of pipeline; Anti-radar and earth design; The electrical engineering budgets . In office buildings to meet the extension of the electricity load and lighting on the basis of the request, on energy conservation, green and beautiful, and other factors complex electrical design. Distribution system designed for use TN-C-S system, from 380/220 V power supply, power substation from the outside to lead buried. Main Selection of fluorescent lighting source, the incandescent lamp. Through the unit capacity calculation method to determine the room illumination required by the number of lamps and lighting of a reasonable choice and layout. Coefficient of the need to use the extension office building to load, the load calculation of choice through cable wires and electrical equipment models. Select the lightning network construction as the Lightning system. And the entire electrical works over the budget. This design is so usable that the new technology and equipment of our country’s electricity design are used. Key words：architecture electric; Illumination; Lamps and lanterns；the method of unit capability; 目 录 第1章 绪 论 1 1.1 建筑电气概况 1 1.2设计原则 1 1.3设计内容 1 第2章 供配电系统设计 2 2.1 负荷分级及供电措施 2 2.1.1 负荷等级 2 2.1.2 三级负荷的供电措施 2 2.2 配电系统的原则 2 2.3 照明供电网络的接地形式 3 2.3.1 N系统接地形式 3 2.3.2 TT系统 3 2.4 照明供电网络的接线形式 3 2.5 本办公楼的负荷分级与供电措施 4 第3章 照度计算 5 3.1 一层照度计算 5 3.1.1 办公室1 5 3.1.2 左质量检查办公室 6 3.1.3 活动室1 7 3.1.4 库房1 8 3.1.5 活动室5 8 3.1.6 值班室 9 3.1.7办公室5 9 3.2 二层照度计算 10 3.2.1办公室1 10 3.2.2活动室1 11 3.2.3办公室6 12 3.2.4活动室4 13 3.2.5档案室1 13 第4章 照明光源选择 15 4.1照明光源选择一般原则 15 4.2照明灯具选择 16 4.3办公照明一般设计原则 16 4.4本办公楼灯具选择 16 第5章 灯具的布置 1
