摘 要

随着科技进步，现代建筑中电气系统在整个建筑物中的重要性越来越明显。办公楼的电气设计除了要满足正常工作需要外，还要本着安全节能的原则为相关人员提供一个安全、方便和舒适的工作环境。本文将围绕“人性化、节能化”的理念，对某商业集团办公楼电气设计进行探讨。

该商业集团办公楼是以办公为主，兼有餐饮、会议、机房、地下车库为一体的综合性建筑，该建筑地下2层，地上25层。总高度为82米，总建筑面积3万平方米，属于一类高层建筑。设计部分包括照明系统，防雷接地系统，电视监控系统，有线电视系统，消防报警及联动系统等方面。

The Design of Lighting System and CCTV For A Commercial Group Office Building

ABSTRACT

With the progress of science and technology, the importance of modern architecture electric system in the whole building is becoming more and more obvious. The electrical design for the office building not only meet the normal work, but also provide a safe, convenient and comfortable working environment for the related personnel in the spirit of safety and energy saving principle .This article will focus on the " humane, energy-saving " concept, to discuss the electrical design for a commercial group office building .

The commercial office building is a comprehensive building . It is primarily used for offices, as a whole,also used for restaurants, meeting rooms, engining rooms and the underground garage. The building has 2 underground floors, 25 floors above the ground . It belongs to a class of high-rise buildings ,its total height is 82 meters and total construction area is 30,000 square meters.The design section includes lighting system, lightning protection and grounding system , CCTV , cable television system as well as fire alarm and linkage system .

Key Words: lighting ；lightning protection and grounding ；CCTV；cable television ；fire alarm and linkage

1前 言

本次设计的题目是某商业集团办公楼照明及电视监控系统设计。通过具体的实例工程设计，初步掌握高层建筑照明系统，防雷接地系统，电视监控系统，有线电视系统，消防报警及联动系统等系统设计的基本方法，更好的将理论和实践相结合。同时在设计的过程中，通过指导老师的讲解，同学之间的讨论，还有自己独立查阅有关文献等方式，系统的学习了建筑电气设计的一般方法和步骤，提高了自己独立完成工程设计的实际操作和研究能力。通过比较详细地学习有关规范，将大学所学的课程及知识应用到自己的专业中去,也为将来的工作打下良好的基础。

本工程为总高度82米，总建筑面积3万平方米的民用普通高层建筑，为一类高层建筑。该商业集团办公楼是以办公为主，兼有餐饮、会议、机房、地下车库为一体的综合性建筑，该建筑地下2层，地上25层。在本设计中，要求完成对该商业集团办公楼强、弱电系统设计，主要包括照明系统，防雷接地系统，电视监控系统，有线电视系统，消防报警及联动系统等设计。论文针对高层民用建筑电气的设计和使用需要，在重点表述强、弱电系统设计与计算的同时，侧重于电气基本理论和基本知识。设计中，总体按照民用建筑设计规范来建立设计的整体思路，并完成强、弱电系统的负荷计算、设备选型、系统构成、照度计算以及施工图的绘制，包括系统图和平面图等。

本毕业设计说明书共分为七章。其中第1章是前言；第2章介绍照明和插座系统设计；第3章为防雷接地系统设计；第4章为电视监控系统设计；第5章为有线电视系统的设计；第6章消防报警及联动系统的设计；第7章为结论。
