范文编号:DQ349   范文字数:16436,页数:36

摘  要
 本范文主要阐述了某多层民用住宅各系统的供配电设计。包括设计的依据、原理，设计的方法和所设计的选择和结论。
 本文共六章，重点设计为强电部分。第1章绪论对设计进行总的说明，第2章、第3章和第4章为强电设计部分，包括负荷计算，照明系统设计和防雷接地的设计；第5章和第六章为消防和弱电部分的设计说明，消防根据规范不需设置，本设计只对消火栓和喷淋进行相关的设计，弱电部分只进行预埋管设计。
 此次设计采用AUTOCAD软件进行绘图设计，总共完成图纸共15幅，其中强电部分9幅，弱电部分6幅，
 本多层民用住宅的电气设计作为文档设计，最终目的是通过设计实践，学习和掌握绘图软件AUTOCAD的使用，培养锻炼了独立分析和解决建筑电气方面问题的能力，为文档之后的学习理清了思路，为工作奠定了坚实的基础。
 
关键词 负荷计算，照明，防雷接地，导线，供配电，
 
Abstract
 This thesis mainly explains the power supply design . Including the basis for the design, principle, design methods and the choice of the design and conclusions.
 The thesis includes six Chapters, focusing on the design for the forceful electric power part . Chapters 1 to make a description of the design , Chapter 2, Chapter 3 and Chapter 4 is the forceful electric power part , Including load calculation, lighting design and the design of Lightning Protection ; Chapter 5 and Chapter 6 is disgen note of the part of fire-fighting and light current , it dosen’t need to set fire-fighting by standards, the disgen only sets hydrant button pressure switch , Water flow indicator and Signal Valve , the part of light current disgin only with the laying of pipeline in advance .
 Graphic design of this disgen uses AUTOCAD . Completed a total of 15 drawings . There are 9 drawings for the forceful electric power part , 6 drawings for lighting .
 electrical design of The multi-storey residential as a graduation disgen , the purpose of this design is to give us a chance of synthetical usage of the knowledge we have learned , Studying and mastering the use of AUTOCAD , it can train our ability to analyze and solve practical problems in Construct electricity in dependently , and help study for Clearing thinking to me . so that the theory is connected with practice and a solid base is made in favor of future work. .

Key Words  load calculation, lighting, Lightning Protection, wire, the power supply,
