消(xiao)防應(ying)急電(dian)(dian)(dian)源是根據(ju)消(xiao)防設(she)施、應(ying)急照(zhao)明、事(shi)故照(zhao)明等(deng)一級(ji)負荷供(gong)電(dian)(dian)(dian)設(she)備需要(yao)而(er)設(she)計生產(chan)。產(chan)品由互投(tou)裝置、自動充到電(dian)(dian)(dian)機、逆(ni)變電(dian)(dian)(dian)源及蓄電(dian)(dian)(dian)池組(zu)等(deng)組(zu)成。在交流電(dian)(dian)(dian)網正常時(shi)經過(guo)互投(tou)裝置給(gei)重要(yao)負載供(gong)電(dian)(dian)(dian)。

　　消(xiao)防(fang)應(ying)急電源在停電時(shi)，能在不同(tong)場合為各種(zhong)用電設備供電。它適用范(fan)圍廣、負載適應(ying)性強(qiang)、安裝方便、效率高。采用集中供電的消(xiao)防(fang)應(ying)急電源可克服其他(ta)供電方式的諸多缺點。

　　消防應(ying)急電(dian)源(yuan)能減少不(bu)必(bi)要的(de)電(dian)能浪費。在應(ying)急事故、照明等用電(dian)場所，它與(yu)轉(zhuan)換效率(lv)較低(di)且長期連續(xu)運行的(de)UPS不(bu)間斷電(dian)源(yuan)相比較，具有更高(gao)的(de)性能價格比。

　　消(xiao)防(fang)應(ying)(ying)急電(dian)(dian)(dian)(dian)(dian)其原理(li)為(wei)：在(zai)市(shi)電(dian)(dian)(dian)(dian)(dian)正常時，由市(shi)電(dian)(dian)(dian)(dian)(dian)經過(guo)輸(shu)出(chu)切(qie)(qie)換(huan)裝(zhuang)置(zhi)給重要負荷(he)供電(dian)(dian)(dian)(dian)(dian)，同(tong)時充(chong)電(dian)(dian)(dian)(dian)(dian)器為(wei)蓄電(dian)(dian)(dian)(dian)(dian)池進行充(chong)電(dian)(dian)(dian)(dian)(dian)或浮充(chong);當(dang)市(shi)電(dian)(dian)(dian)(dian)(dian)斷電(dian)(dian)(dian)(dian)(dian)后或電(dian)(dian)(dian)(dian)(dian)壓超出(chu)供電(dian)(dian)(dian)(dian)(dian)范圍，控(kong)制器啟動逆變器，同(tong)時輸(shu)出(chu)切(qie)(qie)換(huan)裝(zhuang)置(zhi)將(jiang)市(shi)電(dian)(dian)(dian)(dian)(dian)供電(dian)(dian)(dian)(dian)(dian)狀態(tai)立即切(qie)(qie)換(huan)到逆變器供電(dian)(dian)(dian)(dian)(dian)，為(wei)負荷(he)設備提供應(ying)(ying)急供電(dian)(dian)(dian)(dian)(dian);當(dang)市(shi)電(dian)(dian)(dian)(dian)(dian)恢復(fu)時，應(ying)(ying)急電(dian)(dian)(dian)(dian)(dian)源將(jiang)恢復(fu)為(wei)市(shi)電(dian)(dian)(dian)(dian)(dian)供電(dian)(dian)(dian)(dian)(dian)。

　　以上內(nei)容就是(shi)對(dui)消防應(ying)(ying)急(ji)電(dian)源(yuan)是(shi)什么(me)的(de)介紹了，消防應(ying)(ying)急(ji)電(dian)源(yuan)是(shi)以解決應(ying)(ying)急(ji)照明、事故照明、消防設(she)施等(deng)一級負(fu)荷供(gong)(gong)電(dian)設(she)備(bei)為主要目標(biao)，提供(gong)(gong)一種符合(he)消防規范的(de)具有(you)獨立回路的(de)應(ying)(ying)急(ji)供(gong)(gong)電(dian)系統(tong)，該系統(tong)能(neng)夠在應(ying)(ying)急(ji)狀態下提供(gong)(gong)緊(jin)急(ji)供(gong)(gong)電(dian)，用來解決照明用電(dian)或(huo)只有(you)一路市電(dian)缺少第(di)二路電(dian)源(yuan)，或(huo)代替(ti)發電(dian)機組構成第(di)二電(dian)源(yuan)，或(huo)做為需要第(di)三電(dian)源(yuan)的(de)場合(he)使用。
