Abstract Along with the social shape and the advancement, is combining together with the information technique and the structure technique of brain the small zone develops quickly. The shape of the brain small zone is for people tender more conveniently, elegant and easy living condition, it not only includes a service, the space stretch, the electronics infrastructure, the cable supervision etc. serves generally, more important take structure as terrace, gather structure, serve, manage, the electricity automation and correspond by letter the optimization of combination of the network system, tender a safety toward people, efficiently, amenity, facilitation of living condition. This electrical engineering design with the latest brain the shape of the small zone into back ground, involve small zone to provide to go together with the electricity design, weak electricity system design, the single corpus building electricity light, heat and water expense design waits several parts of contents sc. Small zone's providing to go together with the electricity design is the position, type that distributes the condition scheme to change to give or get an electric shock surd the small zone scale and the structure, the main including burden reckon and the select of the related facility; The single corpus structure electricity design is terminate surd the national relevant norms one many layer home buildings of the electricity contract drawing design, the main including light, heat and water expense goes together with an electricity, defending thunder with connect solemn, the complex system cloth line etc. contents. .
Keywords:load calculation; relay protection; electricity light to design; weak electricity system; power supply design;
本设计为小区供配电的设计,设计以“电气工程专业毕业设计任务书与指导书”所提供的设计要求,设计任务为依据,结合国家近年来颁布的建筑标准规范和供电技术的最新发展,依托《工厂供电》《电气照明》《继电保护》的授课内容,并查阅有关的图书资料进行的。
