毕业设计 [论文] 题目:市人大办公楼电气综合设计摘要本设计以国家相关规范为准则，以安全用电、节约能源为指导，着眼于提高办公照明的效率，应用现代电气技术，完成了市人大办公楼的配电、照明、消防系统的设计。
在配电设计中，根据负荷等级，确定供电方式及系统方案；设计中以放射式接线，保证了供电的可靠性；运用需要系数法进行计算负荷，按照规定选择保护电器、电线电缆，达到安全用电和节约能源的目的。
在照明系统设计中，本着节能的原则，选择荧光灯为光源，通过照度计算，确定最佳光源数，为人们创造了一舒适、明亮的生活、工作环境；插座安装的设计避免了拖线板的滥用，满足增加用电设备的需求，提高了用电的安全性。
在消防系统的设计中，通过感烟、感温探测器，手动火灾报警按钮，消防栓按钮等消防电气设备的布置、安装的设计，实现了对各防火区域的防火监测，探测火灾的发生。
同时，消防系统的设计，将探测、监控和手控报警系统与消防广播，房火卷帘门和消防水泵相联，实现消防联动，当有火灾时，探测、监控和手控系统发出火灾信号，有各联动装置发出警报，进行防火隔离和启动自动灭火系统，在疏散人员的同时进行自动灭火，控制、消除火灾隐患，保障该楼内人员、财产的安全。

In the lighting system design, in line with the principle which conserves energy, chooses the fluorescent lamp is the photo source, through the degree of illumination computation, determined the best photo source number, has created one comfortably, the bright life, the leisure environment for the people; The plug installs the design avoided towing the forming blockabusiveness, satisfied the increase current collector the demand, enhanced the security which used electricity. The dynamic system design, completes the electrical machinery the main circuit and the control circuit design, has realized the electrical machinery safe operation. Earths in the anti-radar design, through flat steel and ground steel bar structure docking, anti-radar, earth public earth body, both has safeguarded the earth security, and saved the earth equipment. In the fire prevention system design, through the feeling smoke, the feeling warm detector, the manual fire reports to the police the button, fire prevention electrical equipment and so on hose saddle button arrangement, the installment design, has realized to each area of fire protection fire protection monitor, the survey fire occurrence. At the same time, the fire prevention system design, will survey, the monitoring and the manually controlled alarm system and the fire broadcast, Fang the curtain gate and the fire pump unites, realization fire prevention linkage, when will have the fire, the survey, the monitoring and the hand-controller systemwill send out the fire signal, will have various system to send out the warning, will carry on the fire protection to isolate and to start the automatic fire fighting system, while will disperse personnel's to carry on the automatic fire fighting, the control, the elimination fire hidden danger, will safeguard in this building the personnel, the property safety.Keywords：The office buildings，Electricity design，Power distribution，Illumination，Fire prevention目录摘要 (II)ABSTRACT (III)1绪论 (1)1.1建筑电气概况 (1)1.2设计原则与依据 (1)1.3设计内容 (2)2 照明供配电系统设计 (4)2.1配电方式 (4)2.1.1配电系统 (4)2.1.2设计结果 (4)2.2负荷等级及供电要求 (5)2.2.1负荷等级分类 (5)2.2.2供电要求 (5)2.3照明负荷计算 (7)2.3.1照明负荷计算步骤 (7)2.4导线及电气设备的选择 (8)2.4.1导线型号的选择 (8)2.4.2导线截面的选择 (8)2.4.3电气设备的选择 (9)2.4.4设计结果 (11)3 照明设计 (13)3.1总则 (13)3.2照明光源、灯具选择 (13)3.2.1照明光源的选择 (13)3.2.2照明灯具的选择 (14)3.3照度和照明方式 (14)3.3.1照度和照明方式确定 (15)3.3.2设计结果 (16)3.4照度计算 (16)3.4.1单位容量法计算照度 (16)3.4.2灯具的布置 (24)3.5应急照明设计 (24)3.5.1应急照明分类 (24)3.5.2应急照明灯具选择与布置 (25)3.5.3 应急灯具工作状态 (25)3.5.4 设计结果 (25)3.6开关插座的设计 (26)3.6.1开关的设计及要求 (26)3.6.2插座的设计及要求 (26)4 火灾自动报警控制系统 (27)4.1概述 (27)4.2设计准则 (28)4.3火灾自动报警系统的组成 (29)4.3.1火灾探测器 (29)4.3.2手动火灾报警按扭 (31)4.3.3火灾报警控制器 (32)4.4系统的设置 (33)4.4.1 区域报警控制系统 (33)4.4.2 集中报警控制系统 (33)4.4.3 控制中心报警系统 (34)4.5火灾自动报警系统设计 (34)4.5.1 系统选型 (34)4.5.2 防火区域和报警区域的划分 (35)4.5.3 探测区域和报警区域的划分 (36)4.5.4火灾探测器的选择 (37)4.5.5探测回路的设计 (40)4.5.6手动报警按钮的设置 (40)4.6消防联动的设计 (42)4.6.1 消火栓系统的联动设计方案 (42)4.6.2防排烟系统的联动设计方案 (43)4.6.3火灾事故广播系统设计 (43)4.6.4消防电话设计 (44)4.7线路敷设 (45)4.7.1设计一般原则 (45)4.7.2设计结果 (46)结论 (48)参考文献 (47)致谢 (49)1绪论1.1建筑电气概况现代建筑电气技术虽然是随着建筑业的发展而形成的，但它具有电气工程的鲜明特征，电气照明技术越来越受到重视，同时因照明能耗日益增大,照明系统的效率也成为电气工程界的热点。
