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 adopt 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 contribution 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 talk backing. The focal point originally designed is the strong electricity, design the distribution system of this project and motive force lighting system mainly.
