Abstract
This electrical design of the office building is a graduation design，The purpose of this design is to give us a chance of synthetical 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.
The topic name of this design is the building electrical design of Xin Da Shang Cheng 7# Electrical Design.This thesis mainly explains the electrical design basis ,principle, methods and the conclusion of the design choice in each system in the design of Residential buildings. 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 .
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 major ones are lighting and socket system plan layout, equipment selection, according to the room illumination requirements of the different illumination calculation based on the results of the calculation results choose the appropriate lighting. Also on the supply and lightning protection grounding system design.
The part of the light current mainly including: CATV, elephone and Internet systems and so on.
The design adds up to 20 electric charts.（Including 1Hand-drawn charts），There are one piece of legend, 10 pieces of the strong electric plane drawings and system drawings, and 9 pieces of the weak electric plane drawings and system drawings.
Key Words: Low voltage distribution; Illumination; Plug; CATV; Phone
