甘肃农业大学实验楼照明电气设计.doc

摘 要 随着社会进步和技术发展，建筑电气技术也有了很大的发展，而且在现代建筑发展过程中发挥着重要作用。 本文以AUTOCAD、天正电气软件为设计平台，完成了对甘肃农业大学实验楼内的强电部分的电气设计。主要包括照明系统、平面设计、配电系统设计等，还涉及到电话系统的设计。文中叙述了民用建筑照明的种类、照度标准和照明节能，以及电光源和灯具的选择、布置等方面。在照明光照设计中，首先根据照明场所的功能，确定视觉要求，再根据设计规范确定设计照度；其次选择光源和灯具,确定照明方式和布置灯具的方案。在进行照明电气设计时，对照明负荷进行了计算。依据计算结果合理选择导线截面和敷设方式。最后，利用天正电气软件绘制了该建筑的照明电气平面设计图和配电系统图，并按照建筑电气规范进行了适当的调整。 本文做到严格按照民用建筑电气的标准进行设计，并充分考虑了安全用电、简单操作和经济性等方面。通过对电气强电部分的设计，掌握了照度计算、负荷计算、导线及电缆选择方法，对建筑电气系统设计有了一定程度的了解。 关键字：电气设计；电气照明；照度计算；负荷计算Abstract Along with social progress and technical development, the construction electricity technology has also made great progress, moreover plays an important role in the promotion of modern architecture. The electrical design of the laboratory building of Gansu Agricultural University is completed by using AUTOCAD and Tianzheng electrical software in this thesis. The design includes lighting, graphic design, power distribution network, and involves the telephone system. The paper describes the types of civil lighting, illumination standards and lighting saving energy, as well as electric lighting and lamps selection, and layout etc.In the lighting system design, first of all, determine the visual work place requirements in accordance with the and function of environmental conditions,then design indoor illumination in accordance with design standard for the lighting ;secondly,to choose light sources and lamps, choose the way of lighting and the arrangement of lamps. During electrical lighting design, lighting load gets a reasonable calculation.Then based on the results to choose the wire cross-section and the way of wire laying.Finally, useing Tianzheng electrical drawing electrical lighting software to draw the graphic design and power distribution network of the building,and some appropriate adjustment has been taken in accordance with electrical specifications for the construction. The design is strictly based on the standards of civil electrical design, the safety simple operation and economy of electr
