实验楼电气设计毕业设计论文

摘要

随着建筑电气技术、计算机技术和通信技术的发展，建筑电气工程的内容也越来越多，使建筑电气的概念超出了传统的范围，向智能建筑方向发展。这对电气设计提出了更多要求。建筑电气设计的发展对现代化建筑具有重要意义。

本设计按照电气照明的相关规范，对兰州交通大学五号实验楼进行照明电气设计。首先对实验楼采用单位容量法进行照度计算，进行了光源的选择、灯具的布置、室内配线及布线、配电线路的敷设等。其次对整个大楼进行了负荷计算，对导线、低压控制电器进行了合理的选择。负荷计算对合理选择设备以确保安全可靠性与运行经济性等均起着决定性的作用。电流的测算可用以确定各类开关电气的整定值与导线截面。建筑供配电和照明线路的设计，采用Auto CAD和天正电气作为设计平台，绘制电气平面图、配电系统图。设计还在节能方面做了一定的考虑，例如合理布置导线和采用节能灯具等。

Abstract

With the development of building technology,computer technology and communication technology, the content of electrical engineering is more and more,the concept of building electrical range than the traditional, direction to the intelligent building.Toputup more requiements of electrical design, The development of electrical design modern architecture is important.

This design according to the illumination design related standard, this thesis introduces the electrical lighting design of 5# laboratory building of Lan Zhou Jiao T ong University. Firstly,using unit capacity method to calculate the illuminance of building. It has the choice of light sources, lighting layout, interior

wiring and cabling, as well as the laying of distribution lines. Secondly the whole building has a load calculation, on the reasonable choice is vital to ensure the safety and reliability of equipment and operation of the economy. Current estimates can be used to identify various types of electrical switches for the entire cross-section of the conduit. Lighting design and architectural design are very close to each other and the two should be coordinated with each other. Auto CAD and TIANZHENG software used as a design terrace in building power supply and distribute and lighting lines design, drawing electrical floor plan, power distribution system plans. Energy-saving design also done some considerations, such as rational arrangement of wires and other energy-saving lamps.

Keywords：Unit capacity method，Lighting Design，Lable laying
