某高层住宅建筑电气设计.doc

摘要 随着经济建设的发展，中国当前城市建设发展迅速，其规模之大、范围之广，均是空前的。由于建筑技术和信息技术的相互渗透结合和迅猛发展，在20世纪80年代中期产生了新的建筑类型——智能建筑。本设计是某小区某楼电气系统设计。 本工程为地上12层高档住宅，地上全部为住宅。占地面积约为600平方米，每层层高为3m。室内外高差为0.45m。本工程为一类建筑，二级负荷供电，消防系统及部分重要负荷采用双电源同时供电，电源由小区变电站引来，三相五线制，采用TN—C—S系统，采用树干式配电方式至各分配电箱。 设计包括：供配电系统设计，建筑照明设计，插座布置，防雷与接地，有线电视系统设计，综合布线系统设计，电话系统以及可视对讲系统。 关键词： 建筑电气，照度，布线，负荷计算 Abstract With the development of economic construction, the construction and development of present city of China are fast, its scale big , range is wide, is unprecedented.Technique permeate the combination mutually with the information because of the building technique with fast and fierce development of building electricity technology, in 1980’s age the period the new building type-intelligent buildings turned out. This design is a floor area of a certain electrical system design. For ground house not top-grade of 12 layers in project floors in this , all house above the ground.The floor space is about 600 square meters, it is that each layer is high.3 m. The internal and external discrepancy in elevation of the room is 0. 45m. This engineering is two buildings, and carry to adop the double the power supply the power supply, power supply to come from the transformer substation for second class burthen power supply ,fire fight system and part of importance at the same time ,three modulation four line system, adoption TN-C-S System ,adoption tree trunk type contridution electricity the method give or get an electric shock the box to each allotment. Design and include: For the distribution system to design, the building illumination is designed, the socket is fixed up, defending Ray and earth, the cable television system is designed, the comprehensive wiring system is designed, telephone system and can look at system of talkbacking. The focal point originally designed is the strong electricity, design the distribution system of this project and motive force lighting system mainly.
