1 绪论
1.1 办公楼照明与供配电系统概述
随着人们生活水平的提高，高质量的生活对于建筑物的要求也越来越高，人们对于高层建筑物的要求也越来越高。无论是强电还是弱电系统，其设计均以安全、可靠、经济、便利为原则。对于照明系统的设计来说，照明电气设计通常是在光照设计的基础上进行的，其主要任务是保证电光源和灯具能正常、安全、可靠而经济的工作。
供配电系统的设计主要包括供电方式的确定、导线电缆的选择、线路敷设、保护电器的选择。照明系统设计主要包括照明方式及种类的分类、照度的计算、光源的选择、灯具和插座的选择及布置。所有的设计环节都应以安全为前提，应该尽量做到节能和实现绿色照明。防雷接地系统是保护建筑物安全中很重要的一部分，旨在保护建筑物防止雷击和雷电波入侵。不同地区不同类型建筑物其防雷等级各不相同。一定要以建筑物防雷设计规范为依据，进行防雷措施的选择。此外，在建筑物安全方面还包括等电位联结，将进出建筑物的金属管道等连接到防雷装置上。
建筑电气设计是在认真执行国家技术经济政策、相关国家标准和规范的前提下，进行工业与民用建筑建筑电气的设计，并满足保障人身、设备以及建筑物安全、供电可靠、电能节约、技术先进和经济合理。采用符合国家现行有关标准的高效节能、安全可靠的电气产品，也是建筑电气供配电系统设计可持续发展的要求。
