普通的低(di)壓配電(dian)柜(ju)一般(ban)分為(wei)進線柜(ju)、電(dian)容補償柜(ju)和(he)饋線柜(ju)。他們都(dou)是只有(you)一路(lu)從變壓器(qi)來(lai)的電(dian)源，沒有(you)備用電(dian)源，更不(bu)能進行電(dian)源的切換。

在消防(fang)中使用雙電源控(kong)制(zhi)柜有好處：

當因故停電(dian)(dian)，要(yao)(yao)在很短的時(shi)間內無法恢復供電(dian)(dian)時(shi)，必須使用備(bei)用電(dian)(dian)源(yuan)。雙電(dian)(dian)源(yuan)控制柜(ju)主要(yao)(yao)由雙電(dian)(dian)源(yuan)自動切(qie)換(huan)裝置組成，可(ke)根據需要(yao)(yao)在常用電(dian)(dian)源(yuan)與備(bei)用電(dian)(dian)源(yuan)之間自動切(qie)換(huan)，保(bao)證供電(dian)(dian)的可(ke)靠性和連續性。

將五個部分有效(xiao)的(de)結合(he)，才能夠使(shi)雙電源柜在應用(yong)中(zhong)發(fa)揮(hui)良好的(de)作(zuo)用(yong)，下面我們(men)來舉(ju)例講講雙電源柜里面具體包含了那(nei)些材料。

1、首先是柜(ju)體(ti)，根據不同(tong)的(de)(de)需求會產生大小不同(tong)的(de)(de)柜(ju)體(ti)，如(ru)常見的(de)(de)柜(ju)體(ti)有2000*800*600、2200*1000*600、2000*800*600這種柜(ju)體(ti)能放400以(yi)內的(de)(de)雙電(dian)源，淮安雙電(dian)源柜(ju)廠家，雙電(dian)源大了柜(ju)體(ti)的(de)(de)尺寸也會增加。

雙(shuang)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)自動切換(huan)開關(guan)的(de)工(gong)作原理是(shi)當(dang)常(chang)用電(dian)(dian)(dian)源(yuan)(yuan)(yuan)因故停電(dian)(dian)(dian)或出現故障，在(zai)一(yi)段時間內(nei)無法(fa)恢復供電(dian)(dian)(dian)情況下，切除常(chang)用電(dian)(dian)(dian)各(ge)斷(duan)路(lu)器(qi)拉開雙(shuang)投防倒送(song)開關(guan)至自備(bei)(bei)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)一(yi)側，保持雙(shuang)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)切換(huan)箱內(nei)自備(bei)(bei)電(dian)(dian)(dian)供電(dian)(dian)(dian)斷(duan)路(lu)器(qi)處于斷(duan)開狀態。待自備(bei)(bei)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)機組(zu)運轉正常(chang)時，順序閉(bi)合發電(dian)(dian)(dian)機空氣開關(guan)和自備(bei)(bei)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)控(kong)制柜內(nei)各(ge)斷(duan)路(lu)器(qi)。逐個閉(bi)合各(ge)備(bei)(bei)用電(dian)(dian)(dian)源(yuan)(yuan)(yuan)斷(duan)路(lu)器(qi)，向各(ge)負載送(song)電(dian)(dian)(dian)。
