某大学教学实验楼的建筑电气设计(含CAD图)(任务书,开题报告,论文说明书15400字,CAD图25张)
摘  要
本工程为某大学教学实验楼的建筑电气设计，设置的电气系统有配电系统、照明系统、防雷接地及安全措施。
配电系统的设计需要根据对应规范与其他等相关条件，完成对不同用电设备是否为一级、二级或三级负荷等级的确定并计算出对应的负荷容量，选择合适可靠，如双重电源供电等类似的供电方式，确定了负荷容量及对应供电方式后，进行对线缆型号规格以及敷设方式、断路器与其他开关的型号规格以及安装方式的确定。
照明系统可以简单划分正常照明与应急照明这两大类，顾名思义正常照明即正常情况下使用的照明设备，其需要满足人们日常生活生产中基本照明需求；应急照明则是为了对应火灾等紧急情况下的照明设备。本工程主要设置的有备用照明与消防应急照明及疏散指示照明。应急照明的布置需视情况而定，如变电室、排烟机房等火灾时仍需正常工作的消防设备用房设置备用照明，其照明不低于正常照明照度；疏散走道、楼梯间等应布置疏散指示系统，系统满足相关的控制要求与照度标准。
防雷接地及安全措施设计需要确定建筑的防雷等级，低压配电系统接地型式的确定，防直击雷、防雷电感应、防电磁脉冲以及等电位联结的做法。

Architectural electrical design of a university teaching experimental building
Abstract
This project is the electrical design of the building of a university teaching and experimental building. The electrical system is equipped with power distribution system, lighting system, lightning protection grounding and safety measures.
The design of the power distribution system needs to determine whether the different power equipment is the primary, secondary or tertiary load level according to the corresponding specifications and other relevant conditions and calculate the corresponding load capacity, choose a suitable and reliable, such as dual power supply. After determine the load capacity and the corresponding power supply mode, determine the cable model specifications and laying methods, model specifications and installation methods of the circuit breakers and other switches.
The lighting system can be divided into two categories: normal lighting and emergency lighting. As the name suggests, normal lighting is the lighting equipment used under normal conditions, which needs to meet the basic lighting needs of people in daily life production; emergency lighting is to respond to fires and other emergency situations. The main settings of this project are standby lighting and fire emergency lighting and evacuation indicating lighting. The layout of emergency lighting shall be determined according to the situation. For example, the fire-fighting equipment room that needs to work normally in the fire room, smoke exhaust machine room, etc. shall be set up with standby lighting, and the lighting shall not be lower than the normal lighting illumination; evacuation walkways, stairwells, etc. should be equipped with an evacuation indication system, and the system meets relevant control requirements and illuminance standards.
Lightning protection grounding and safety measures need to determine the lightning protection level of the building, the determination of the grounding type of the low-voltage distribution system, anti-direct lightning, lightning protection, anti-electromagnetic pulse and equipotential bonding.
