PAGE \* ROMAN II PAGE V PAGE I 摘 要 当今社会，电力技术的不断发展与完善，推动了经济的发展，加速了工业技术的发展。电力的应用已经遍布人们生活的方方面面。一个优质的供配电系统设计对于建筑物来说十分重要。建工院属于办公楼，人流量较大，需要满足的要求也较多。在设计过程中要尽可能的考虑到每层楼、每间房的具体需求，按照需求进行设计。 本次设计的供配电系统，主要涉及强电系统的设计以及相关计算等。主要包括计算负荷量的统计、变压器选择、短路电流计算、无功功率补偿及补偿电容器的选型、高低开关选型、导线选型、变压器的二次整定以及接地防雷保护系统设计等方面。 本次设计完成一层接地设计、顶层防雷设计以及每层的平面走线图、一次系统图；完成一层至五层每层配电箱的系统图。根据计算及选型为每图标注相应的导线、开关、控制柜等型号。同时根据系统图，按照行业规范完成了所有的连线以及高低压设备的布置。 关键字：建工院，供配电系统，负荷统计，系统图 ABSTRACT The electric power technology development impelled human societys progress, also has accelerated the technical development. The electric power application already proliferated the aspects which the people lived. High quality supplies the electrical power distribution system design to be extremely important regarding the building. The construction work courtyard belongs to the office building, the stream of people quantity is big, needs to satisfy the request are also many. In the design process must as far as possible consideration each building, each room concrete demand, carry on the design according to the demand. This design for the electrical power distribution system, mainly involves the strong electricity system the design as well as the correlation computation and so on. Mainly includes the computation load the statistics, the short-circuit current computation, the transformer shaping, the reactive power computation as well as the compensation, the high and low pressure equipment choice, wire aspects and so on shaping, transformer two installations as well as earth anti-radar protection. This design completes an earth design, the top layer anti-radar design as well as each level plane walks the graph, a diagram; Completes one to five each distributing box diagrams. According to computation and shaping ，we should label the corresponding wire, switch, control cubicle. Simultaneously acts according to the diagram, has completed all segments as well as the high and low pressure equipment arrangement according to the prof
