1m. Low voltage distribution system: this project to adopt the TN-S three-phase five line, level 1 load the power supply system of double power supply, switching at the end. Lighting system: the intensity of illumination computation, lamps and lanterns selection, lamps and lanterns decorate and lighting distribution lines for laying, etc. This project by a skilled lamps and lanterns. Fire control system: the engineering level to level of fire protection system protection, the centralized alarm system. Determine the setting of the fire detectors and kinds of each part, detection area in the number of detector and decorate, calculation finished fire alarm and fire control, emergency radio, linkage fire telephone calls and such device design. Lightningproof grounding system: the project according to the three kinds of design lightningproof grounding, the roof of the phi 10 galvanized the distant parapet, roofing along the four zhou Ming to avoid laying with USES part of the structure, the column for two advocate muscle led off the assembly line, lightning protection of the basement floor of pile foundation reinforcement fabric comprehensive grounding device, lightningproof grounding and electrical equipment grounding share grounding device comprehensive. Total supply into line is in total equipotential connection do, toilet do local equipotential connection.
Keywords: low voltage distribution; Lighting; Fire; Lightningproof grounding
第1章 绪论
建筑工程的电气设计中，需要讲究设计的可操作性、延续性、系统性和整体协调性；并做到设计依据完备，可靠；设计程序严谨、合理；设计内容正确、详实；设计深度满足各阶段的需要；设计文件规范、工整、符合有关规定，确保安全可靠、经济合理。系统配置和设备选型，应与工程的性质、规模、功能要求，建筑环境、经济发展水平和人文****惯相适应，应适当考虑专业技术和建筑功能扩展的可能性，以延长工程的寿命，节省投资，提高系统的性能价格比。
本次设计的电气系统包括：低压配电系统、照明系统（包括正常照明和应急照明）、消防系统、防雷接地系统。通过理论和设计相结合，提高综合运用专业知识的能力，掌握电气工程的设计程序和方法，学会使用技术规范解决相关设计问题。
