電源箱其實在火災自動報警系統中還是比較常見的一種消防設備，但還是有很多人不是很了解電源箱，不知道它是做什么用的。

       火(huo)災自動報警(jing)系(xi)統(tong)是弱電(dian)(dian)(dian)(dian)系(xi)統(tong)，電(dian)(dian)(dian)(dian)壓為直流(liu)24V。那火(huo)災報警(jing)系(xi)統(tong)中的(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)是由(you)誰提(ti)供(gong)的(de)呢？其實系(xi)統(tong)中電(dian)(dian)(dian)(dian)源(yuan)(yuan)一般有三個，一是火(huo)災報警(jing)控(kong)制(zhi)器，但由(you)于(yu)火(huo)災報警(jing)控(kong)制(zhi)器本身的(de)電(dian)(dian)(dian)(dian)流(liu)輸出比較小，所(suo)以負(fu)載量有限，系(xi)統(tong)中的(de)用電(dian)(dian)(dian)(dian)設(she)備(bei)多(duo)的(de)話火(huo)災報警(jing)控(kong)制(zhi)器就無(wu)法(fa)承載，現(xian)場(chang)用電(dian)(dian)(dian)(dian)設(she)備(bei)也(ye)就無(wu)法(fa)工作了；二(er)是消防(fang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)盤(pan)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)盤(pan)是電(dian)(dian)(dian)(dian)源(yuan)(yuan)提(ti)供(gong)者，大多(duo)安裝在柜(ju)式或琴(qin)臺式的(de)火(huo)災報警(jing)控(kong)制(zhi)器機柜(ju)里(li)；三是消防(fang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)箱(xiang)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)箱(xiang)與電(dian)(dian)(dian)(dian)源(yuan)(yuan)盤(pan)是同種類設(she)備(bei)，不過外觀以及安裝位(wei)置不同，電(dian)(dian)(dian)(dian)源(yuan)(yuan)箱(xiang)是安裝于(yu)現(xian)場(chang)的(de)，為現(xian)場(chang)用電(dian)(dian)(dian)(dian)設(she)備(bei)提(ti)供(gong)24V電(dian)(dian)(dian)(dian)。

       電(dian)(dian)(dian)源(yuan)(yuan)箱(xiang)是一種DC24V大容量(liang)電(dian)(dian)(dian)源(yuan)(yuan)輸出設(she)備(bei)(bei)，在火災報警控(kong)制(zhi)系(xi)統中，可(ke)作為聯動(dong)(dong)(dong)控(kong)制(zhi)系(xi)統的電(dian)(dian)(dian)源(yuan)(yuan)使用，為聯動(dong)(dong)(dong)控(kong)制(zhi)模(mo)塊及被(bei)控(kong)設(she)備(bei)(bei)供電(dian)(dian)(dian)。電(dian)(dian)(dian)源(yuan)(yuan)箱(xiang)以交流(liu)220V作為主(zhu)電(dian)(dian)(dian)源(yuan)(yuan)，同時(shi)內置(zhi)DC24V/7Ah密封鉛電(dian)(dian)(dian)池作為備(bei)(bei)用電(dian)(dian)(dian)源(yuan)(yuan)，采用開關電(dian)(dian)(dian)源(yuan)(yuan)穩壓電(dian)(dian)(dian)路及備(bei)(bei)電(dian)(dian)(dian)浮充電(dian)(dian)(dian)路，具有輸出過流(liu)自動(dong)(dong)(dong)保(bao)護(hu)(hu)、主(zhu)備(bei)(bei)電(dian)(dian)(dian)切換和(he)完善的備(bei)(bei)電(dian)(dian)(dian)自動(dong)(dong)(dong)充電(dian)(dian)(dian)及備(bei)(bei)電(dian)(dian)(dian)過放電(dian)(dian)(dian)保(bao)護(hu)(hu)功能。

       它的(de)(de)作(zuo)用(yong)上(shang)面(mian)也已經(jing)提到，就是給現(xian)場消(xiao)防設(she)備(bei)供電(dian)(dian)(dian)(dian)的(de)(de)。智能(neng)型電(dian)(dian)(dian)(dian)源(yuan)箱(xiang)(xiang)可對主、備(bei)電(dian)(dian)(dian)(dian)及電(dian)(dian)(dian)(dian)源(yuan)輸(shu)(shu)出狀(zhuang)態(tai)進行監控，可報主、備(bei)電(dian)(dian)(dian)(dian)故障、輸(shu)(shu)出故障，還(huan)具有輸(shu)(shu)出電(dian)(dian)(dian)(dian)壓、輸(shu)(shu)出電(dian)(dian)(dian)(dian)流的(de)(de)顯(xian)示功能(neng)，可直(zhi)觀地觀察電(dian)(dian)(dian)(dian)源(yuan)箱(xiang)(xiang)的(de)(de)工(gong)作(zuo)狀(zhuang)態(tai)。
