摘 要
摘 要
本工程以国家现行相关规范以及相关标准图集为设计依据，因本工程的各训练馆独立使用且各场馆高度差较大，故电源进线均单独引进，各干线均由室外箱变采用电缆埋地引进，电压等级220/380V，并采用TN-C-S系统，消防用电、应急照明为二级负荷，其他为三级负荷，备用电源为EPS，供电时间不小于90分钟。
本工程照明采用节能型I类灯具，并依据《建筑照明设计标准》GB50034-2004 相关规定设计。
本工程为防雷等级为三级，采用?12的镀锌圆钢沿屋脊等位置敷设避雷带。利用柱内主筋做引下线，其间距不大于25m，并采用共用接地形式，接地电阻不大于1?。
本工程保护对象为二级，依据国家相关规范设计，以北大青鸟产品参数为设计依据。

Abstract
Abstract
This project with the national relevant specification and standard atlas as the design basis, due to the independent use of the engineering training center and venues height difference, so the power line are separately introduced, the trunk is composed of outdoor box with cable buried introduction, 220/380V voltage grade, and the use of TN-C-S systems, fire power, emergency lighting to load two, other three level load, the standby power supply of EPS, the time of not less than 90 minutes.
This project lighting using energy-saving I lamps, and based on the \lighting design of buildings GB50034-2004 The relevant provisions of design.
This works for the lightning protection level of three, the galvanized steel bar along the ridge position such as laying lightning band. Using a cylindrical reinforcements do lead line, the distance of not more than 25m, and the use of common grounding, grounding resistance of less than.
The protection object of this project is two level, according to national relevant specification design, the Beida Jade Bird products as design basis.
Keywords: lighting; lightning protection; fire
