Abstract
According to the national norms, standards, engineering Atlas and other material, using the knowledge, including basic theory and professional engineering practice, I independently complete the required tasks on Weak Electrical Design and mastered the design calculation procedures, methods.
The design is Electrical Design for a Primary and Secondary Comprehensive Building, building height of 21.3m, single floor area of 3133m2, a total of five. The first floor are the amphitheater, primary visual reading room, school multi-media classrooms, a reception lounge and duty room, Security - Fire Control Centre, also set in the first floor; the second floor are the Primary school library and school offices and meeting rooms; the third floor are the Multi-purpose report halls, Middle school seeing and hearing reading rooms, primary and secondary school computer rooms and meeting rooms; the fourth floor are secondary school library and primary and secondary school reading rooms; the fifth floor are electron prepares the classrooms, library and reading rooms for secondary school teachers, primary and secondary schools science and technology center; five-story roof is the astronomical observatory.
The engineering design divides into the strong electricity part and the weak electricity part:
The strong electricity part primary coverage includes: Low Voltage Distribution System, Lighting system and lightning protection grounding system design, including load calculations, illumination calculation etc.
The weak electricity part primary coverage includes: Telephone, Internet, Security Video Surveillance System, CATV, Fire alarm control design.
This is designed to practice through the design of the integrated use of the knowledge, apply theory to reality, and exercise independent analysis and capacity of solving building electrical design problems for the future work to lay a solid foundation. The design is completed a total of twenty four drawings, including one design shows and eleven drawings for the strong electric part, twelve drawings for the weak electric part, drawing using AutoCAD drawing software.

Key words: supply and distribution system; illumination; lightning protection; grounding system; fire-fighting; integrated wiring; video surveillance
