消(xiao)防應急(ji)電源是根據消(xiao)防設(she)(she)施、應急(ji)照(zhao)明、事故照(zhao)明等(deng)一級負(fu)荷供電設(she)(she)備(bei)需要(yao)而設(she)(she)計生(sheng)產(chan)(chan)。產(chan)(chan)品由(you)互投裝置(zhi)(zhi)、自動(dong)充到電機、逆變電源及蓄電池組等(deng)組成。在交流(liu)電網正常時經(jing)過互投裝置(zhi)(zhi)給重(zhong)要(yao)負(fu)載供電。

　　消(xiao)(xiao)防應急電源(yuan)在(zai)停電時，能(neng)在(zai)不同場合為各種用電設備供電。它適用范圍(wei)廣、負(fu)載適應性強、安裝方便、效率高。采用集中供電的(de)消(xiao)(xiao)防應急電源(yuan)可克(ke)服其(qi)他供電方式的(de)諸多缺點。

　　消防應急電(dian)源能(neng)減少不必(bi)要的(de)電(dian)能(neng)浪費。在(zai)應急事故、照明等用(yong)電(dian)場所，它(ta)與轉換(huan)效率較低且長期連續運行的(de)UPS不間斷電(dian)源相比較，具有更高的(de)性(xing)能(neng)價格比。

　　消防應急(ji)電(dian)(dian)(dian)(dian)其原(yuan)理為(wei)(wei)(wei)(wei)：在市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)正(zheng)常(chang)時(shi)(shi)，由(you)市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)經(jing)過輸(shu)出切(qie)換裝置(zhi)給重(zhong)要(yao)負(fu)荷供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)，同(tong)時(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)器為(wei)(wei)(wei)(wei)蓄電(dian)(dian)(dian)(dian)池進(jin)行充(chong)電(dian)(dian)(dian)(dian)或浮充(chong);當市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)斷電(dian)(dian)(dian)(dian)后或電(dian)(dian)(dian)(dian)壓超出供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)范圍，控制器啟動逆(ni)變(bian)器，同(tong)時(shi)(shi)輸(shu)出切(qie)換裝置(zhi)將市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)狀態(tai)立即(ji)切(qie)換到逆(ni)變(bian)器供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)，為(wei)(wei)(wei)(wei)負(fu)荷設備(bei)提(ti)供(gong)(gong)(gong)應急(ji)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian);當市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)恢復時(shi)(shi)，應急(ji)電(dian)(dian)(dian)(dian)源將恢復為(wei)(wei)(wei)(wei)市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)。

　　以(yi)上(shang)內容就是(shi)(shi)對消防(fang)(fang)應急(ji)電(dian)(dian)源(yuan)(yuan)是(shi)(shi)什么(me)的介紹了(le)，消防(fang)(fang)應急(ji)電(dian)(dian)源(yuan)(yuan)是(shi)(shi)以(yi)解決(jue)應急(ji)照(zhao)明、事故照(zhao)明、消防(fang)(fang)設施等一級負荷供(gong)(gong)電(dian)(dian)設備為主要(yao)目標，提(ti)供(gong)(gong)一種符合消防(fang)(fang)規范(fan)的具有獨(du)立(li)回路(lu)(lu)的應急(ji)供(gong)(gong)電(dian)(dian)系統(tong)，該(gai)系統(tong)能夠(gou)在應急(ji)狀態下提(ti)供(gong)(gong)緊急(ji)供(gong)(gong)電(dian)(dian)，用(yong)來解決(jue)照(zhao)明用(yong)電(dian)(dian)或只有一路(lu)(lu)市電(dian)(dian)缺少第二路(lu)(lu)電(dian)(dian)源(yuan)(yuan)，或代替發(fa)電(dian)(dian)機組構成第二電(dian)(dian)源(yuan)(yuan)，或做為需要(yao)第三電(dian)(dian)源(yuan)(yuan)的場合使用(yong)。
