P摘 要BR本论文主要阐述了**公司办公楼的各系统电气设计的设计依据、原则和方法及设计的结论，内容分别为：配电系统设计、照明系统设计、防雷接地系统设计和工程概预算。配电系统设计部分包括：供配电方案确定，电气设备选择，线管选择与布置，负荷计算等；照明系统设计部分包括：光源选择、灯具选择、照明方式选择以及照度计算等；防雷接地系统设计部分包括：建筑物防雷措施，原则，方案。BR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、环保、美观、舒适等因素进行综合建筑电气设计。供配电系统设计采用TN－C－S系统，由380/220V电源供电，电源由室外变电所直埋地引来。照明光源主要选用荧光灯，普通吸顶灯通过单位容量法进行照度计算来确定房间所需要的灯具数量，并且对灯具进行合理地选择与布置。主要采用需要系数法对办公楼进行负荷计算，根据负荷计算所得值选择电缆导线型号及用电设备。选取避雷带作为本建筑的防雷系统。并且对整个电气工程进行概预算。 /P P关键词 ：照度；配电；光源；负荷； BRnbsp;BRAbstractBRThis paper described the office building electrical systems design based on the design, design principles and methods and conclusions, which were: distribution system design, lighting design, mine grounding system design and engineering over the budget. Distribution system design include: distribution programme for the identification, electrical equipment selection, selection and arrangement of lines, load calculation; design of the lighting system include: source selection, choice of lamps, lighting and illumination choose calculation; Lightning Protection System design include: mine-building measures, in principle, the programme.BROn the foundation of satisfies the electricity load which the extension part of the office building daily uses and the illumination condition, the synthesis construction and electricity design is based on some factors, such as energy conservation, environmental protection, artistic and so on. The pattern of power supplying system is TN－C－S and the power source which is buried straightly and is bring in by outdoor transformer substation. The choice of the primary illumination photo-source is the fluorescent lamp and the incandescent lamp. The quantity of the lamps is determined by the degree of illumination computation by the way of unit capacity and then carries on the reasonable arrangement to the lamps and lanterns. Computation is carried on
