建筑電氣英文翻譯

1、建筑電氣電氣工程設(shè)計包括兩個主要的設(shè)計方面。主要是一部分的電能的轉(zhuǎn)換及分配和電力的供配、照明系統(tǒng)、防雷接地系統(tǒng)。一般來說,建筑主要的變化包括:高壓和低壓配電系統(tǒng)、變壓器、備用電源系統(tǒng)。電力系統(tǒng)包括配電和控制，室內(nèi)和室外照明系統(tǒng)包括所有類型的照明，防雷系統(tǒng)包括入侵波防護、閃電傳感器、接地、等電位連接和局部等電位連接等。輔助等電位連接等。在短短的20年里,系統(tǒng)在技術(shù)和產(chǎn)品的面貌發(fā)生了翻天覆地的變化。許多的設(shè)計理念也發(fā)生了巨大的變化。開關(guān)設(shè)備如高壓系統(tǒng)的第一個斷路器油斷路器，后來油斷路器的逐步發(fā)展,不僅規(guī)模大,但是一般都包含油物質(zhì)。由于開關(guān)設(shè)備尺寸較大,我們還必須建立獨立的設(shè)備房間,占據(jù)了大量的建筑

2、面積?，F(xiàn)在真空斷路器和六氟化硫斷路器,不僅體積小,而且短路容量大，外殼尺寸遠小于原來的櫥柜，并且斷路器沒有任何油,防火性能大大提高。而且斷路器和其他低壓設(shè)備在一個房間里,這樣即節(jié)省空間又方便管理。過去大容量的低壓斷路器,短路電流容量逐漸變大,規(guī)模也逐漸變小,而且更加穩(wěn)定,使系統(tǒng)運行更加安全可靠,為設(shè)計帶來了方便。向著智能化低壓斷路器方向發(fā)展,斷路器各種參數(shù)可以通過總線工業(yè)控制,信號直接傳輸?shù)接嬎銠C。 干式變壓器的出現(xiàn),對建筑電氣設(shè)計帶來了極大的方便,因為沒有變壓器油泄漏和火災(zāi)的可能性,以便它可以很容易地安裝在建筑本身,甚至直接到負荷中心。它還消除變壓器對油的需求限制,構(gòu)建大容量設(shè)備時可以使用干

3、式變壓器。在實際工程設(shè)計中曾應(yīng)用四個臺灣2500kVA干式變壓器。 在使用緊急發(fā)電機方面,從性能和尺寸的角度來看,比過去進步很多。除了使用柴油發(fā)電機；應(yīng)急照明使用EPS備用電源；中斷供電在一個毫秒以內(nèi)的設(shè)備,可以使用UPS。 電力設(shè)備的控制從單一元件的控制到控制繼電器控制變化。除了更好的性能的各種組件的規(guī)模較小,也降低控制箱的規(guī)模。由于數(shù)字技術(shù)更多的運用于控制能達到最佳的控制狀態(tài)來控制設(shè)備。進一步提高了節(jié)能的效果。 照明系統(tǒng)從過去單一光源、燈具和低效率的狀態(tài)向更廣泛的前景發(fā)展。建筑中使用的光源可供選擇的品種數(shù)量很多。光的發(fā)光效率和色調(diào)在向著高效的方向發(fā)展,燈具不斷地改進其效率和不同形式的燈具運

4、用于不同場合。例如,普通的熒光燈鎮(zhèn)流器由普通的鎮(zhèn)流器向節(jié)能型鎮(zhèn)流器方向發(fā)展。還對諧波組件的大小進行精簡,生產(chǎn)低諧波電子鎮(zhèn)流器。許多措施如配件和燈具的使用,可以滿足設(shè)計要求,同時能實現(xiàn)不同的體系結(jié)構(gòu)、照明要求的各種場所。無論照明和室內(nèi)裝飾照明還是道路照明和戶外庭院建筑的光照明,所有的都展示了照明技術(shù)的發(fā)展和建筑照明的好處與便利。 另一個設(shè)計使用于電氣設(shè)備和其他設(shè)備,如雙電源開關(guān)的互投。與傳統(tǒng)的專業(yè)生產(chǎn)產(chǎn)品相比,除了傳統(tǒng)的功率切換外,雙電源還能滿足每個其他電子設(shè)備的需要,極大地提高供電的可靠性和連續(xù)性。 電力電纜和電線是被廣泛使用的產(chǎn)品。過去的電線電纜,種類稀少?，F(xiàn)在引入各種電纜,從普通阻燃PVC

5、電纜到耐火、少煙無鹵、防電磁干擾環(huán)境的電纜等。導線材料從普通的礦物絕緣絕緣材料到總線絕緣,高效絕緣等分支機構(gòu)。電力建設(shè)中這些技術(shù)是安全、可靠、方便的,提供了一個有效的環(huán)境保護。 針對特殊需求分布、建設(shè)的一些新設(shè)備得到了廣泛的應(yīng)用。例如大型醫(yī)院手術(shù)室醫(yī)療機構(gòu)漏電保護、漏電監(jiān)測系統(tǒng)等。 技術(shù)的發(fā)展強大在很多地方都有顯現(xiàn)如實際工程和技術(shù)人員,以及我們自己的經(jīng)驗。如此巨大的發(fā)展為中國的電力建設(shè)和電力建設(shè)安全使用奠定了良好的基礎(chǔ)也創(chuàng)造了條件。 隨著建筑智能化技術(shù)的深入應(yīng)用,一些設(shè)備、系統(tǒng)控制和控制系統(tǒng)已逐漸成為一個專業(yè)性的監(jiān)控,并具有開放建筑設(shè)備監(jiān)控系統(tǒng)通信協(xié)議、互聯(lián)網(wǎng)和通信系統(tǒng)。建筑物內(nèi)如自動功率控制

6、系統(tǒng),采用現(xiàn)場總線技術(shù)的數(shù)據(jù)采集和處理,集中控制變量分配系統(tǒng)實現(xiàn)遠程監(jiān)控和遠程控制以及遠程無人變電站的實現(xiàn)。連續(xù)收集和分析系統(tǒng)能提前給出建議或警告,以方便系統(tǒng)的安全運行。自動功率控制系統(tǒng)利用計算機技術(shù)、信息技術(shù)、控制技術(shù)、傳感器技術(shù)、通信網(wǎng)絡(luò)技術(shù)、電力電子技術(shù)等綜合技術(shù),它基本上可以取代傳統(tǒng)的二次回路而且接線簡單、性能可靠、易于維護。與此同時,根據(jù)建筑的能耗進行的第二次重大節(jié)能照明控制系統(tǒng)也會逐步實現(xiàn)。專業(yè)照明控制系統(tǒng)已經(jīng)廣泛應(yīng)用于許多建筑物。照明控制由一個實時傳感器控制定時控制。此外,現(xiàn)場控制、遠程控制和控制多種靈活的控制現(xiàn)場,達到最大的能量利用,同時實現(xiàn)功能和人性化的舒適的照明系統(tǒng)。 各種

7、建筑標準也相應(yīng)出臺，如1980年代末標準建筑設(shè)計防火規(guī)范GBJ16-87；1990年代民用建筑照明設(shè)計標準GBJ133-90；民用建筑電氣設(shè)計規(guī)范JGJ/ T16 - 92；工業(yè)企業(yè)照明設(shè)計標準GB50034 - 92；高層民用建筑設(shè)計防火規(guī)范GB50045 - 95；供配電系統(tǒng)設(shè)計規(guī)范GB50052 - 95；l0kV及以下變電所設(shè)計規(guī)范GB50053 - 94；低壓配電設(shè)計規(guī)范GB50054 - 95；通用用電設(shè)備設(shè)計規(guī)范GB50055 - 93；建筑物防雷設(shè)計規(guī)范GB50057-94等等。緊隨后的是建筑電氣設(shè)計基礎(chǔ)建設(shè)電氣設(shè)計的標準化。 智能建筑技術(shù)只是一種手段，配備智能功能、強調(diào)效率、

8、能耗低、更干凈,真正實現(xiàn)以人為本。在實現(xiàn)節(jié)能的前提下,提高建筑的功能、環(huán)境保護和可持續(xù)發(fā)展的目標。構(gòu)建可持續(xù)發(fā)展的實現(xiàn)從戰(zhàn)略的角度來看,注重環(huán)境保護，保持生態(tài)系統(tǒng)穩(wěn)定?？沙掷m(xù)發(fā)展是一個永恒的主題，經(jīng)過多年的實踐,在一個理性和務(wù)實的態(tài)度下,以實際需要和實際應(yīng)用為標準,不是盲目地追隨片面而是追求全面、先進的智能系統(tǒng),在技術(shù)上做到領(lǐng)先。設(shè)計需做了合理的投資,使用不同的功能。根據(jù)投資和管理需求的具體情況來確定先進的、可靠的、經(jīng)濟合理的和最優(yōu)的方案，這個概念現(xiàn)在已經(jīng)成為智能建筑行業(yè)的共識。建筑智能技術(shù)使所有的學院和大學的建設(shè)開辟了這一技術(shù)相應(yīng)的專業(yè)課程和促進了相關(guān)專業(yè)學生的發(fā)展。 智能建筑技術(shù)包括:建筑

9、設(shè)備自動控制系統(tǒng)、安全系統(tǒng)、停車場管理系統(tǒng)、火災(zāi)自動報警和消防系統(tǒng)、通信和計算機網(wǎng)絡(luò)系統(tǒng)、綜合布線系統(tǒng)、廣播系統(tǒng)、有線電視系統(tǒng)、視頻會議系統(tǒng)等,超過10個子系統(tǒng)的集成。是我國第一個獨立于國內(nèi)建筑智能技術(shù)系統(tǒng)集成子系統(tǒng)的開發(fā)。 1、20世紀的建筑設(shè)備監(jiān)控系統(tǒng)的發(fā)展由1980年代的集中監(jiān)控開始,由于可靠性差、速度慢，1990年代后已經(jīng)很少使用,并取代了分布式控制。在1990年代末,隨著計算機技術(shù)、控制技術(shù)、網(wǎng)絡(luò)和通信技術(shù)開發(fā)和集成,監(jiān)控施工設(shè)備技術(shù)發(fā)展迅速。 2、 安全技術(shù)和安全措施也逐步發(fā)展,包括中央監(jiān)控、入侵警報、訪問控制(門)、巡邏削減等更多的周邊防御和其他子系統(tǒng)。安全系統(tǒng)從最初的子系統(tǒng)相互

10、獨立的到各子系統(tǒng)之間相互聯(lián)系。大大增加了安全性、可靠性和實時為人們的工作、學習和生活安全保障。閉路電視監(jiān)控系統(tǒng)從模擬到數(shù)字的方向發(fā)展,整個安全系統(tǒng)的規(guī)模也在運動數(shù)字系統(tǒng)、集成的方向發(fā)展。 3、 運用通信網(wǎng)絡(luò)技術(shù)的智能建筑通信網(wǎng)絡(luò),包括計算機網(wǎng)絡(luò)、雙向有線電視傳輸網(wǎng)絡(luò)和電話通訊網(wǎng)絡(luò)。前兩個智能網(wǎng)絡(luò)作為一個寬帶主干網(wǎng)絡(luò)把幾乎所有的信息技術(shù)和信息資源管理的幾乎所有的用戶連接到一起。在1990年代中期之前，有一個為所有類型的網(wǎng)絡(luò)和用戶的市場。但在1990年代末,由于以太網(wǎng)連接的靈活性和優(yōu)越的性能、易于維護和使用等優(yōu)點,ICT網(wǎng)絡(luò)逐漸在列表中。以太網(wǎng)傳輸速率,從最初的10Mbps,100Mbps 到1

11、Gbps,10Gbps甚至更高的利率。智能建筑電話網(wǎng)絡(luò)(ISDN,SL)目前用于語音通信、數(shù)據(jù)和圖像的窄帶寬數(shù)據(jù)通信,它讓人們通過通信網(wǎng)絡(luò)、電視、電話會議等功能實現(xiàn)相互交流。智能訪問技術(shù)的關(guān)鍵是與外界建立聯(lián)系,它使世界變得越來越小。人們的工作、生活發(fā)生了劇大的變化。智能建筑訪問網(wǎng)絡(luò)或互聯(lián)網(wǎng),越來越多的高帶寬需求的接收,滿足日益增長的用戶需求數(shù)據(jù)通信。在有線電視網(wǎng)絡(luò)的發(fā)展同時,無線網(wǎng)絡(luò)由于其靈活性,也進入了一個快速發(fā)展階段。從2003年的基于最初的路線的輪詢策略的研究到現(xiàn)在超過100兆赫。移動互聯(lián)網(wǎng)正為人們提供很大的方便,并在許多領(lǐng)域發(fā)展?jié)摿薮?，網(wǎng)絡(luò)正在成為趨勢。 4、 綜合布線技術(shù)PDS是智

12、能建筑數(shù)據(jù)、語音和多媒體的通信平臺。綜合布線技術(shù)進入中國市場以來,因其優(yōu)異的性能,并且對于智能建筑的國內(nèi)市場來說是一個新概念、新技術(shù),在建筑業(yè)立即引起了巨大的反響。該技術(shù)已廣泛應(yīng)用于所有類型的智能建筑。為了滿足網(wǎng)絡(luò)傳輸帶寬和新產(chǎn)品的開發(fā)速度，PDS引入3線、5線到6線,甚至提高標準到七線系統(tǒng)的產(chǎn)品,以滿足千兆網(wǎng)絡(luò)的需求。提高網(wǎng)絡(luò)的傳輸速率,以適應(yīng)已經(jīng)投入10G網(wǎng)絡(luò)市場的發(fā)展。新的多模和單模光纖傳輸媒介作為一個很好的材料將被廣泛使用。從銅線、光纖電纜、技術(shù)和產(chǎn)品的不斷更新，PDS充分反映了智能建筑的快速發(fā)展,新技術(shù)的應(yīng)用和廣闊的發(fā)展前景。 5、 智能建筑系統(tǒng)集成技術(shù)一般連接各個子網(wǎng)絡(luò)。每個子系統(tǒng)

13、的操作預(yù)計將完成他們的工作,但尚未達到共享信息資源。為了實現(xiàn)有效的管理,各個子系統(tǒng)之間的信息資源共享、系統(tǒng)集成。在系統(tǒng)集成過程中,選擇平臺集成、網(wǎng)絡(luò)結(jié)構(gòu)、集成子系統(tǒng)的范圍是不同的、集成模型也是不同的。隨著計算機技術(shù)、網(wǎng)絡(luò)技術(shù)、控制技術(shù)、顯示技術(shù)的發(fā)展,建筑設(shè)備監(jiān)控系統(tǒng)和其他系統(tǒng)通過計算機網(wǎng)絡(luò)連接。完成基于建筑設(shè)備監(jiān)控系統(tǒng)的系統(tǒng)集成模式。平等的在各自的系統(tǒng)集成,建立一個網(wǎng)絡(luò)管理系統(tǒng)集成。作為一個子系統(tǒng)可以降低現(xiàn)場控制網(wǎng)絡(luò)集成。實時數(shù)據(jù)子系統(tǒng)、開放、行業(yè)標準接口,轉(zhuǎn)換成統(tǒng)一的格式存儲在數(shù)據(jù)庫或服務(wù)器系統(tǒng)集成。綜合網(wǎng)絡(luò)管理系統(tǒng)實現(xiàn)統(tǒng)一管理子系統(tǒng)程序、監(jiān)控和信息交換系統(tǒng)集成, 系統(tǒng)集成實現(xiàn)協(xié)議的各個子

14、系統(tǒng)之間的聯(lián)系有關(guān)控制和信息共享。提高管理效率,增強處理突發(fā)事件的能力和節(jié)約能源的目的、節(jié)省人力。這是建筑設(shè)備管理系統(tǒng)(BMS)。系統(tǒng)集成不是我們的目的,而是為了增強建筑的功能和技術(shù)手段,提高管理效率,整合內(nèi)容不是更好,但根據(jù)使用和管理的需要,以及成熟的技術(shù),該系統(tǒng)是可靠和合理的投資。有效管理的前提是集成的需求。 6、 智能住宅區(qū) 1990年代國際電子智能住宅提出的理念。智能建筑技術(shù)逐漸蔓延到居民區(qū),在最初幾個經(jīng)濟較發(fā)達的沿海城市已經(jīng)成功。智能技術(shù)開始建設(shè)居住小區(qū)的住宅和公共建筑。智能建筑智能技術(shù)迅速擴展,已成為智能建筑發(fā)展的一個重要市場。公共建筑和住宅智能化,這是市場的需求,也是實際的發(fā)展需

15、求。智能設(shè)計研究所將中國住宅將放在一個重要位置,為住宅提供一個智能平臺。住宅的智能設(shè)計是先進的和具有挑戰(zhàn)性的領(lǐng)域。住宅小區(qū)智能化技術(shù)的發(fā)展可以分為以下方面:系統(tǒng)設(shè)計強調(diào)以人為本的設(shè)計理念,應(yīng)該迎合居民所有級別的方便、安全、舒適和處理功能的要求，處理好先進和實用之間的關(guān)系和合理的投資。安全系統(tǒng)從一個單獨的安全子系統(tǒng)為家庭和社區(qū)結(jié)合防御到國防安全的技術(shù)體系。從單個運營商寬帶訪問信息、通信模式選項、xD-SL寬帶接入網(wǎng)絡(luò)、一個雙向有線電視網(wǎng)絡(luò),形成地區(qū)計算機網(wǎng)絡(luò)發(fā)展。當?shù)鼐用窨梢韵硎苄畔⒑屯ㄓ嵎?wù)從一個寬帶互聯(lián)網(wǎng)服務(wù)地區(qū)接收更多的局域網(wǎng)的延伸增值服務(wù)。機電設(shè)備的自動監(jiān)控、電子水位遠程復制、音頻和視頻
