樓梯間消防應急照明設計
1、設計要求
樓(lou)(lou)梯間(jian)(jian)作(zuo)為建筑(zhu)物內部(bu)(bu)的(de)(de)核心組成部(bu)(bu)分,不僅是人流相(xiang)對(dui)集中、最易(yi)發(fa)生(sheng)(sheng)意外的(de)(de)地(di)方而(er)且(qie)還承擔應(ying)(ying)急(ji)疏(shu)散的(de)(de)重(zhong)(zhong)要任務(wu)。在(zai)發(fa)生(sheng)(sheng)火災或(huo)者是突然斷(duan)電等情況時,樓(lou)(lou)梯間(jian)(jian)的(de)(de)消防(fang)應(ying)(ying)急(ji)照明(ming)將發(fa)揮重(zhong)(zhong)要作(zuo)用因此應(ying)(ying)高度(du)重(zhong)(zhong)視樓(lou)(lou)梯間(jian)(jian)的(de)(de)消防(fang)應(ying)(ying)急(ji)照明(ming)設計(ji)。GB 50016-2014《建筑(zhu)設計(ji)防(fang)火規(gui)范》中規(gui)定在(zai)封閉式(shi)或(huo)防(fang)煙式(shi)的(de)(de)樓(lou)(lou)梯間(jian)(jian)都應(ying)(ying)設置(zhi)消防(fang)應(ying)(ying)急(ji)燈具,并且(qie)對(dui)樓(lou)(lou)梯間(jian)(jian)內的(de)(de)應(ying)(ying)急(ji)疏(shu)散照度(du)也有(you)強(qiang)制性要求(qiu)(一般要求(qiu)地(di)面(mian)的(de)(de)最低水平照度(du)應(ying)(ying)該高于5.0 lx)。此外,消防(fang)應(ying)(ying)急(ji)照明(ming)設計(ji)過程中需(xu)要合理選擇應(ying)(ying)急(ji)照明(ming)系(xi)統供電控制方式(shi),井(jing)應(ying)(ying)通過計(ji)算方法驗證應(ying)(ying)急(ji)照明(ming)的(de)(de)照度(du)是否滿足(zu)規(gui)范性的(de)(de)要求(qiu)和標(biao)準值的(de)(de)需(xu)要。
(1)燈具種類
隨著(zhu)相關消防照(zhao)明法規的健全與(yu)完善,消防應急照(zhao)明燈具的種類(lei)也不(bu)斷增多,性能不(bu)斷提高,技術不(bu)斷發展。按(an)照(zhao)供電形(xing)式劃分,目前常用的消防應急燈具主要(yao)分為(wei)2種:
①自帶電(dian)(dian)源型消(xiao)(xiao)防(fang)應(ying)急(ji)燈(deng)(deng)具(ju)(ju)。該類(lei)燈(deng)(deng)具(ju)(ju)是我國普(pu)諞使用(yong)的消(xiao)(xiao)防(fang)應(ying)急(ji)燈(deng)(deng)具(ju)(ju)之一(yi),一(yi)旦電(dian)(dian)源被切斷(duan),其自帶的蓄電(dian)(dian)池(chi)即可供電(dian)(dian)并且每一(yi)個燈(deng)(deng)具(ju)(ju)內部(bu)還配有電(dian)(dian)子(zi)元器件,可以起到(dao)變壓、充電(dian)(dian)、穩壓以及蓄電(dian)(dian)的作用(yong)。當消(xiao)(xiao)防(fang)應(ying)急(ji)照(zhao)(zhao)明燈(deng)(deng)具(ju)(ju)進行檢(jian)修時(shi),可以去掉電(dian)(dian)池(chi)充電(dian)(dian),方便下次正常使用(yong)。自帶電(dian)(dian)源型消(xiao)(xiao)防(fang)應(ying)急(ji)燈(deng)(deng)具(ju)(ju)優勢明顯,供電(dian)(dian)可靠性(xing)高,轉換(huan)速度快,電(dian)(dian)池(chi)損壞對燈(deng)(deng)具(ju)(ju)影響相(xiang)對較(jiao)(jiao)小等;其缺點在(zai)于投資大,受到(dao)電(dian)(dian)池(chi)容(rong)量大小的限制,具(ju)(ju)的照(zhao)(zhao)明時(shi)間比較(jiao)(jiao)短(duan),運行管理(li)和維護要求較(jiao)(jiao)高等。通常情況下,在(zai)建(jian)筑層(ceng)次校對或規模較(jiao)(jiao)小的建(jian)筑物樓梯(ti)間,消(xiao)(xiao)防(fang)應(ying)急(ji)燈(deng)(deng)具(ju)(ju)較(jiao)(jiao)少,因此宜(yi)采用(yong)自帶電(dian)(dian)源型消(xiao)(xiao)防(fang)應(ying)急(ji)燈(deng)(deng)具(ju)(ju)。
②集(ji)中(zhong)(zhong)(zhong)(zhong)供(gong)電(dian)(dian)(dian)(dian)(dian)型應(ying)(ying)急(ji)燈(deng)具(ju)。在(zai)某(mou)些(xie)大型建(jian)筑工程中(zhong)(zhong)(zhong)(zhong),集(ji)中(zhong)(zhong)(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)供(gong)電(dian)(dian)(dian)(dian)(dian)型消(xiao)(xiao)防(fang)(fang)應(ying)(ying)急(ji)燈(deng)具(ju)比較(jiao)受人(ren)們(men)的青睞,主要(yao)原因在(zai)于(yu)這(zhe)種消(xiao)(xiao)防(fang)(fang)應(ying)(ying)急(ji)燈(deng)具(ju)內沒有獨立的電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan),當正常照(zhao)(zhao)明電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)被切斷時,供(gong)電(dian)(dian)(dian)(dian)(dian)來源(yuan)(yuan)主要(yao)集(ji)中(zhong)(zhong)(zhong)(zhong)于(yu)供(gong)電(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統。這(zhe)種形式(shi)的應(ying)(ying)急(ji)照(zhao)(zhao)明系(xi)(xi)統省略了燈(deng)具(ju)內部部分復(fu)雜(za)的電(dian)(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)(dian)路,并且可以在(zai)專(zhuan)用(yong)房間內設置集(ji)中(zhong)(zhong)(zhong)(zhong)供(gong)電(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統,一旦發生事故(gu),集(ji)中(zhong)(zhong)(zhong)(zhong)供(gong)電(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統就(jiu)會自(zi)(zi)動投(tou)切。與(yu)自(zi)(zi)帶蓄電(dian)(dian)(dian)(dian)(dian)池的消(xiao)(xiao)防(fang)(fang)應(ying)(ying)急(ji)燈(deng)具(ju)相(xiang)對比,集(ji)中(zhong)(zhong)(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)控(kong)制型消(xiao)(xiao)防(fang)(fang)應(ying)(ying)急(ji)燈(deng)具(ju)方(fang)便集(ji)中(zhong)(zhong)(zhong)(zhong)管理,用(yong)戶可以自(zi)(zi)行查(cha)(cha)看用(yong)電(dian)(dian)(dian)(dian)(dian)情(qing)況。此外,該種消(xiao)(xiao)防(fang)(fang)應(ying)(ying)急(ji)燈(deng)具(ju)還具(ju)有進行消(xiao)(xiao)防(fang)(fang)監督檢查(cha)(cha)以及延(yan)長(chang)燈(deng)具(ju)使用(yong)壽(shou)命等優(you)勢,方(fang)便維護和管理。但是此種燈(deng)具(ju)也(ye)存在(zai)一定缺(que)陷,一旦消(xiao)(xiao)防(fang)(fang)應(ying)(ying)急(ji)照(zhao)(zhao)明電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)出現(xian)故(gu)障(zhang),就(jiu)會對正常的照(zhao)(zhao)明造成(cheng)影響。

綜上所述,選擇消防應急照明燈具(ju),充(chong)分(fen)考(kao)慮建筑物功能、性質等方面(mian)的因(yin)素。
2、供配電系統分析
(1)設計分析
消(xiao)防應(ying)急(ji)(ji)(ji)(ji)照明(ming)系統(tong)需要具備獨(du)立(li)的(de)電(dian)(dian)(dian)(dian)源(yuan)。獨(du)立(li)照明(ming)電(dian)(dian)(dian)(dian)源(yuan)應(ying)該和常(chang)(chang)規(gui)照明(ming)電(dian)(dian)(dian)(dian)源(yuan)分離開(kai),比較常(chang)(chang)見的(de)獨(du)立(li)于饋電(dian)(dian)(dian)(dian)線路(lu)的(de)電(dian)(dian)(dian)(dian)源(yuan)有發電(dian)(dian)(dian)(dian)機組(zu)、蓄電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)源(yuan)等形式。因此常(chang)(chang)用(yong)的(de)消(xiao)防應(ying)急(ji)(ji)(ji)(ji)照明(ming)配(pei)電(dian)(dian)(dian)(dian)系統(tong)主要有3種:一是(shi)(shi)以(yi)發電(dian)(dian)(dian)(dian)機組(zu)作為(wei)消(xiao)防應(ying)急(ji)(ji)(ji)(ji)照明(ming)電(dian)(dian)(dian)(dian)源(yuan),二是(shi)(shi)以(yi)蓄電(dian)(dian)(dian)(dian)池(chi)作為(wei)消(xiao)防應(ying)急(ji)(ji)(ji)(ji)照明(ming)電(dian)(dian)(dian)(dian)源(yuan),三(san)是(shi)(shi)以(yi)自帶自動轉換裝(zhuang)置的(de)蓄電(dian)(dian)(dian)(dian)池(chi)應(ying)急(ji)(ji)(ji)(ji)燈作為(wei)消(xiao)防應(ying)急(ji)(ji)(ji)(ji)照明(ming)電(dian)(dian)(dian)(dian)源(yuan)。
以發電(dian)(dian)(dian)(dian)機組(zu)作(zuo)為(wei)消(xiao)防應急照明電(dian)(dian)(dian)(dian)源(yuan)(yuan)時(shi),需(xu)要在配變電(dian)(dian)(dian)(dian)站周圍(wei)設計一段低(di)(di)壓應急母線(xian),然后(hou)使(shi)用(yong)(yong)斷路器將低(di)(di)壓應急母線(xian)和變電(dian)(dian)(dian)(dian)所的低(di)(di)壓母線(xian)進行(xing)連接,供電(dian)(dian)(dian)(dian)時(shi)從變電(dian)(dian)(dian)(dian)站輸出(chu)電(dian)(dian)(dian)(dian)。當(dang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)發生故(gu)障的情況下,發電(dian)(dian)(dian)(dian)機就(jiu)(jiu)(jiu)會自行(xing)啟(qi)動。應急母線(xian)就(jiu)(jiu)(jiu)會和正常電(dian)(dian)(dian)(dian)源(yuan)(yuan)斷開,并采用(yong)(yong)發電(dian)(dian)(dian)(dian)機供電(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)源(yuan)(yuan)恢(hui)置(zhi)正常后(hou),延緩(huan)一段時(shi)間就(jiu)(jiu)(jiu)會返回到之前的供電(dian)(dian)(dian)(dian)狀態。
以(yi)(yi)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)作為(wei)消防應急(ji)照(zhao)明(ming)電(dian)(dian)(dian)(dian)(dian)源時(shi)可以(yi)(yi)選(xuan)用(yong)燈內自帶的(de)(de)(de)具有自動轉(zhuan)換(huan)(huan)裝(zhuang)(zhuang)置(zhi)的(de)(de)(de)應急(ji)燈,并根據具體的(de)(de)(de)實(shi)際(ji)情況,將常(chang)用(yong)照(zhao)明(ming)裝(zhuang)(zhuang)置(zhi)的(de)(de)(de)裝(zhuang)(zhuang)設(she)(she)開關進行分(fen)散,不(bu)(bu)常(chang)用(yong)的(de)(de)(de)照(zhao)明(ming)裝(zhuang)(zhuang)置(zhi)剛(gang)無需(xu)裝(zhuang)(zhuang)設(she)(she)開關,如果(guo)樓梯出(chu)口的(de)(de)(de)標(biao)志性(xing)燈需(xu)要裝(zhuang)(zhuang)設(she)(she)開關時(shi),需(xu)要采取(qu)集中(zhong)裝(zhuang)(zhuang)設(she)(she)的(de)(de)(de)方式,并專門(men)管理。需(xu)要注意(yi)的(de)(de)(de)是(shi),在給應急(ji)燈浮充電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)專用(yong)電(dian)(dian)(dian)(dian)(dian)源線中(zhong),不(bu)(bu)需(xu)要設(she)(she)置(zhi)專門(men)的(de)(de)(de)開關線路。作為(wei)應急(ji)電(dian)(dian)(dian)(dian)(dian)源的(de)(de)(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)所需(xu)要的(de)(de)(de)轉(zhuan)換(huan)(huan)時(shi)間(jian)(jian)(jian)一般比較短,因此供電(dian)(dian)(dian)(dian)(dian)過程中(zhong)持續的(de)(de)(de)時(shi)間(jian)(jian)(jian)也是(shi)比較短的(de)(de)(de)。相反,發電(dian)(dian)(dian)(dian)(dian)機的(de)(de)(de)供電(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)(jian)(jian)相對(dui)較長,它的(de)(de)(de)轉(zhuan)換(huan)(huan)過程也需(xu)要較長的(de)(de)(de)時(shi)間(jian)(jian)(jian)。所以(yi)(yi),在整(zheng)個照(zhao)明(ming)設(she)(she)計中(zhong)需(xu)要將蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)和發電(dian)(dian)(dian)(dian)(dian)機的(de)(de)(de)供電(dian)(dian)(dian)(dian)(dian)進行組臺(tai),然后設(she)(she)置(zhi)自動轉(zhuan)換(huan)(huan)的(de)(de)(de)時(shi)間(jian)(jian)(jian),在電(dian)(dian)(dian)(dian)(dian)路出(chu)現故障的(de)(de)(de)情況下,可以(yi)(yi)直接轉(zhuan)換(huan)(huan)到電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)供電(dian)(dian)(dian)(dian)(dian),點亮應急(ji)燈,幫助人(ren)們繼續正常(chang)工(gong)作或(huo)是(shi)進行應急(ji)疏散,如果(guo)不(bu)(bu)是(shi)瞬(shun)時(shi)性(xing)的(de)(de)(de)停電(dian)(dian)(dian)(dian)(dian),時(shi)間(jian)(jian)(jian)較長的(de)(de)(de)情況下就可以(yi)(yi)轉(zhuan)換(huan)(huan)到發電(dian)(dian)(dian)(dian)(dian)機供電(dian)(dian)(dian)(dian)(dian)。
如(ru)果采用自動(dong)轉換裝置的蓄(xu)電(dian)(dian)池應急(ji)(ji)(ji)燈,可以(yi)從常(chang)規照明(ming)箱(xiang)引出單獨回路的應急(ji)(ji)(ji)照明(ming)電(dian)(dian)源,也可以(yi)直接從應急(ji)(ji)(ji)照明(ming)電(dian)(dian)源上引出,如(ru)果回路出現斷(duan)電(dian)(dian)情況(kuang)時(shi)由電(dian)(dian)池供電(dian)(dian)的應急(ji)(ji)(ji)燈就會燃亮。
(2)系統要求
