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 thesis mainly explains the electrical design basis ,principle, methods and the conclusion of the design choice in each system in the design of certain office building. The thesis includes six Chapters. previous four Chapters are mostly about the design of the forceful electric power Part ;Chapter 5 and 6 are mostly about the design of the light current and fire-fighting.The part of the forceful electric power mainly including: the distribution system of the low voltage, lighting system and rounding for lightening systematical compose ,among others include load calculation, illumination calculation .The part of the light current mainly including: CATV, Public Broadcasting System, Closed Circuit Monitoring TV and Premises Distribution System and so on.The part of the fire-fighting mainly including: the design of the warning system and linked system etc.
This electrical design of the office building is a graduation design,The purpose of this design is to give us a chance of synthetically usage of the knowledge we have learned. Besides, it can train our ability to analyze and solve practical problems in Construct electricity in dependently so that the theory is connected with practice and a solid base is made in favor of future work.
