摘 要建筑电气是以电能、电气设备和电气技术为手段，创造、维持与改善室内外空间的电、光、热、声环境的一门重要学科，它在人们的日常生活中发挥着极大的作用。本次设计完成了兰州交通大学四号实验楼电气设计。设计内容主要有楼层的照度计算、灯具的选择、开关的选择、负荷计算、插座的选择、导线的选择、电缆的选择、应急照明的设计、配电箱的选择等。在照明设计中，照度计算采用工程中常用的“单位容量法”。普通照明设备选用了嵌入式荧光灯，在此基础上完成了电气照明的平面布置图，并根据需要对该建筑的应急照明给出了具体的设计。为每个实验室安装了单相插座，并完成了插座回路的布置。配电设计中，负荷计算采用的是“需用系数法”。通过负荷计算，完成了整个实验楼的配电系统设计，并且在各层楼都安装了应急照明灯。.本设计采用“天正电气 8.0”绘图软件绘制了电气照明平面图、配电系统图和电气说明图。关键词：建筑电气；照明；照度计算；负荷计算AbstractBuilding electricity is based on electric power, electricity equipments and electricity technique,and also a subject for creating, maintaining and improving light, heat, voice, indoors and outdoors environment. It plays a great role in people's daily life.The paper completes the electrical lighting design of the forth experimental building of Lanzhoujiaotong university. The main design elements include illumination calculation of floor, choice of lamps and switching, load calculation, socket option, wire choice, and choice, emergency lighting design, choice of power distribution box, mine of laboratory building, and so on.In the lighting design, illumination calculation uses the "units of capacity” which is commonly used in the project. General lighting equipment chooses the top embedded fluorescent light. On the basis, the layout plan of the electrical lighting is completed, and the specific design of emergency lighting is conducted in accordance with the needs of construction. Single-phase power outlets are installed for each ...
