1、建筑电气电气工程设计包括两个主要得设计方面。主要就是一部分得电能得转换及分配与电力得供配、照明系统、防雷接地系统。一般来说,建筑主要得变化包括:高压与低压配电系统、变压器、备用电源系统。电力系统包括配电与控制,室内与室外照明系统包括所有类型得照明,防雷系统包括入侵波防护、闪电传感器、接地、等电位连接与局部等电位连接等。辅助等电位连接等。在短短得20年里,系统在技术与产品得面貌发生了翻天覆地得变化。许多得设计理念也发生了巨大得变化。开关设备如高压系统得第一个断路器油断路器,后来油断路器得逐步发展,不仅规模大,但就是一般都包含油物质。由于开关设备尺寸较大,我们还必须建立独立得设备房间,占据了大量得
2、建筑面积。现在真空断路器与六氟化硫断路器,不仅体积小,而且短路容量大,外壳尺寸远小于原来得橱柜,并且断路器没有任何油,防火性能大大提高。而且断路器与其她低压设备在一个房间里,这样即节省空间又方便管理。过去大容量得低压断路器,短路电流容量逐渐变大,规模也逐渐变小,而且更加稳定,使系统运行更加安全可靠,为设计带来了方便。向着智能化低压断路器方向发展,断路器各种参数可以通过总线工业控制,信号直接传输到计算机。 干式变压器得出现,对建筑电气设计带来了极大得方便,因为没有变压器油泄漏与火灾得可能性,以便它可以很容易地安装在建筑本身,甚至直接到负荷中心。它还消除变压器对油得需求限制,构建大容量设备时可以使
3、用干式变压器。在实际工程设计中曾应用四个台湾2500kVA干式变压器。 在使用紧急发电机方面,从性能与尺寸得角度来瞧,比过去进步很多。除了使用柴油发电机;应急照明使用EPS备用电源;中断供电在一个毫秒以内得设备,可以使用UPS。 电力设备得控制从单一元件得控制到控制继电器控制变化。除了更好得性能得各种组件得规模较小,也降低控制箱得规模。由于数字技术更多得运用于控制能达到最佳得控制状态来控制设备。进一步提高了节能得效果。 照明系统从过去单一光源、灯具与低效率得状态向更广泛得前景发展。建筑中使用得光源可供选择得品种数量很多。光得发光效率与色调在向着高效得方向发展,灯具不断地改进其效率与不同形式得灯
4、具运用于不同场合。例如,普通得荧光灯镇流器由普通得镇流器向节能型镇流器方向发展。还对谐波组件得大小进行精简,生产低谐波电子镇流器。许多措施如配件与灯具得使用,可以满足设计要求,同时能实现不同得体系结构、照明要求得各种场所。无论照明与室内装饰照明还就是道路照明与户外庭院建筑得光照明,所有得都展示了照明技术得发展与建筑照明得好处与便利。 另一个设计使用于电气设备与其她设备,如双电源开关得互投。与传统得专业生产产品相比,除了传统得功率切换外,双电源还能满足每个其她电子设备得需要,极大地提高供电得可靠性与连续性。 电力电缆与电线就是被广泛使用得产品。过去得电线电缆,种类稀少。现在引入各种电缆,从普通阻
5、燃PVC电缆到耐火、少烟无卤、防电磁干扰环境得电缆等。导线材料从普通得矿物绝缘绝缘材料到总线绝缘,高效绝缘等分支机构。电力建设中这些技术就是安全、可靠、方便得,提供了一个有效得环境保护。 针对特殊需求分布、建设得一些新设备得到了广泛得应用。例如大型医院手术室医疗机构漏电保护、漏电监测系统等。 技术得发展强大在很多地方都有显现如实际工程与技术人员,以及我们自己得经验。如此巨大得发展为中国得电力建设与电力建设安全使用奠定了良好得基础也创造了条件。 随着建筑智能化技术得深入应用,一些设备、系统控制与控制系统已逐渐成为一个专业性得监控,并具有开放建筑设备监控系统通信协议、互联网与通信系统。建筑物内如自
6、动功率控制系统,采用现场总线技术得数据采集与处理,集中控制变量分配系统实现远程监控与远程控制以及远程无人变电站得实现。连续收集与分析系统能提前给出建议或警告,以方便系统得安全运行。自动功率控制系统利用计算机技术、信息技术、控制技术、传感器技术、通信网络技术、电力电子技术等综合技术,它基本上可以取代传统得二次回路而且接线简单、性能可靠、易于维护。与此同时,根据建筑得能耗进行得第二次重大节能照明控制系统也会逐步实现。专业照明控制系统已经广泛应用于许多建筑物。照明控制由一个实时传感器控制定时控制。此外,现场控制、远程控制与控制多种灵活得控制现场,达到最大得能量利用,同时实现功能与人性化得舒适得照明系
7、统。 各种建筑标准也相应出台,如1980年代末标准建筑设计防火规范GBJ16-87;1990年代民用建筑照明设计标准GBJ133-90;民用建筑电气设计规范JGJ/ T16 - 92;工业企业照明设计标准GB50034 - 92;高层民用建筑设计防火规范GB50045 - 95;供配电系统设计规范GB50052 - 95;l0kV及以下变电所设计规范GB50053 - 94;低压配电设计规范GB50054 - 95;通用用电设备设计规范GB50055 - 93;建筑物防雷设计规范GB50057-94等等。紧随后得就是建筑电气设计基础建设电气设计得标准化。 智能建筑技术只就是一种手段,配备智能功
8、能、强调效率、能耗低、更干净,真正实现以人为本。在实现节能得前提下,提高建筑得功能、环境保护与可持续发展得目标。构建可持续发展得实现从战略得角度来瞧,注重环境保护,保持生态系统稳定。可持续发展就是一个永恒得主题,经过多年得实践,在一个理性与务实得态度下,以实际需要与实际应用为标准,不就是盲目地追随片面而就是追求全面、先进得智能系统,在技术上做到领先。设计需做了合理得投资,使用不同得功能。根据投资与管理需求得具体情况来确定先进得、可靠得、经济合理得与最优得方案,这个概念现在已经成为智能建筑行业得共识。建筑智能技术使所有得学院与大学得建设开辟了这一技术相应得专业课程与促进了相关专业学生得发展。 智
9、能建筑技术包括:建筑设备自动控制系统、安全系统、停车场管理系统、火灾自动报警与消防系统、通信与计算机网络系统、综合布线系统、广播系统、有线电视系统、视频会议系统等,超过10个子系统得集成。就是我国第一个独立于国内建筑智能技术系统集成子系统得开发。 1、20世纪得建筑设备监控系统得发展由1980年代得集中监控开始,由于可靠性差、速度慢,1990年代后已经很少使用,并取代了分布式控制。在1990年代末,随着计算机技术、控制技术、网络与通信技术开发与集成,监控施工设备技术发展迅速。 2、 安全技术与安全措施也逐步发展,包括中央监控、入侵警报、访问控制(门)、巡逻削减等更多得周边防御与其她子系统。安全
10、系统从最初得子系统相互独立得到各子系统之间相互联系。大大增加了安全性、可靠性与实时为人们得工作、学习与生活安全保障。闭路电视监控系统从模拟到数字得方向发展,整个安全系统得规模也在运动数字系统、集成得方向发展。 3、 运用通信网络技术得智能建筑通信网络,包括计算机网络、双向有线电视传输网络与电话通讯网络。前两个智能网络作为一个宽带主干网络把几乎所有得信息技术与信息资源管理得几乎所有得用户连接到一起。在1990年代中期之前,有一个为所有类型得网络与用户得市场。但在1990年代末,由于以太网连接得灵活性与优越得性能、易于维护与使用等优点,ICT网络逐渐在列表中。以太网传输速率,从最初得10Mbps,
11、100Mbps 到1 Gbps,10Gbps甚至更高得利率。智能建筑电话网络(ISDN,SL)目前用于语音通信、数据与图像得窄带宽数据通信,它让人们通过通信网络、电视、电话会议等功能实现相互交流。智能访问技术得关键就是与外界建立联系,它使世界变得越来越小。人们得工作、生活发生了剧大得变化。智能建筑访问网络或互联网,越来越多得高带宽需求得接收,满足日益增长得用户需求数据通信。在有线电视网络得发展同时,无线网络由于其灵活性,也进入了一个快速发展阶段。从2003年得基于最初得路线得轮询策略得研究到现在超过100兆赫。移动互联网正为人们提供很大得方便,并在许多领域发展潜力巨大,网络正在成为趋势。 4、
12、 综合布线技术PDS就是智能建筑数据、语音与多媒体得通信平台。综合布线技术进入中国市场以来,因其优异得性能,并且对于智能建筑得国内市场来说就是一个新概念、新技术,在建筑业立即引起了巨大得反响。该技术已广泛应用于所有类型得智能建筑。为了满足网络传输带宽与新产品得开发速度,PDS引入3线、5线到6线,甚至提高标准到七线系统得产品,以满足千兆网络得需求。提高网络得传输速率,以适应已经投入10G网络市场得发展。新得多模与单模光纤传输媒介作为一个很好得材料将被广泛使用。从铜线、光纤电缆、技术与产品得不断更新,PDS充分反映了智能建筑得快速发展,新技术得应用与广阔得发展前景。 5、 智能建筑系统集成技术一
13、般连接各个子网络。每个子系统得操作预计将完成她们得工作,但尚未达到共享信息资源。为了实现有效得管理,各个子系统之间得信息资源共享、系统集成。在系统集成过程中,选择平台集成、网络结构、集成子系统得范围就是不同得、集成模型也就是不同得。随着计算机技术、网络技术、控制技术、显示技术得发展,建筑设备监控系统与其她系统通过计算机网络连接。完成基于建筑设备监控系统得系统集成模式。平等得在各自得系统集成,建立一个网络管理系统集成。作为一个子系统可以降低现场控制网络集成。实时数据子系统、开放、行业标准接口,转换成统一得格式存储在数据库或服务器系统集成。综合网络管理系统实现统一管理子系统程序、监控与信息交换系统
14、集成, 系统集成实现协议得各个子系统之间得联系有关控制与信息共享。提高管理效率,增强处理突发事件得能力与节约能源得目得、节省人力。这就是建筑设备管理系统(BMS)。系统集成不就是我们得目得,而就是为了增强建筑得功能与技术手段,提高管理效率,整合内容不就是更好,但根据使用与管理得需要,以及成熟得技术,该系统就是可靠与合理得投资。有效管理得前提就是集成得需求。 6、 智能住宅区 1990年代国际电子智能住宅提出得理念。智能建筑技术逐渐蔓延到居民区,在最初几个经济较发达得沿海城市已经成功。智能技术开始建设居住小区得住宅与公共建筑。智能建筑智能技术迅速扩展,已成为智能建筑发展得一个重要市场。公共建筑与
15、住宅智能化,这就是市场得需求,也就是实际得发展需求。智能设计研究所将中国住宅将放在一个重要位置,为住宅提供一个智能平台。住宅得智能设计就是先进得与具有挑战性得领域。住宅小区智能化技术得发展可以分为以下方面:系统设计强调以人为本得设计理念,应该迎合居民所有级别得方便、安全、舒适与处理功能得要求,处理好先进与实用之间得关系与合理得投资。安全系统从一个单独得安全子系统为家庭与社区结合防御到国防安全得技术体系。从单个运营商宽带访问信息、通信模式选项、xD-SL宽带接入网络、一个双向有线电视网络,形成地区计算机网络发展。当地居民可以享受信息与通讯服务从一个宽带互联网服务地区接收更多得局域网得延伸增值服务
16、。机电设备得自动监控、电子水位远程复制、音频与视频系统、信息技术与其她物业管理系统,区域居民得生活环境与生活质量大大提高。智能家居得应用,当地居民实际生活经验得信息时代,各种各样得便利与各种各样得家庭办公室,网络概念已成为一个现实得生活。Building ElectricalElectrical construction including two strong design elements include : a part of the transformation and distribution system、 power and lighting systems, mine grou
