低壓雙電源開關柜其原(yuan)理是(shi)通(tong)過主用電(dian)源(yuan)和備(bei)用電(dian)源(yuan)的(de)自動(dong)切換來(lai)實(shi)現的(de)，當主電(dian)路(lu)停電(dian)或(huo)出現故障時，線(xian)路(lu)系統會自動(dong)切換至備(bei)用電(dian)源(yuan)線(xian)路(lu)。一(yi)般采用接觸器(qi)或(huo)繼(ji)電(dian)器(qi)實(shi)現自動(dong)切換，不同搭配方(fang)(fang)案(an)其工作(zuo)原(yuan)理也是(shi)不同的(de)。下面介紹三種配電(dian)方(fang)(fang)案(an)的(de)工作(zuo)原(yuan)理。

一、方案一

兩個接(jie)觸器(qi)實(shi)現(xian)切(qie)換備用電(dian)源(yuan)的(de)線圈(quan)走主(zhu)接(jie)觸器(qi)的(de)常閉點(dian)，主(zhu)電(dian)源(yuan)接(jie)觸器(qi)吸(xi)合主(zhu)電(dian)路導通(tong)。主(zhu)電(dian)源(yuan)斷(duan)電(dian)，備用電(dian)源(yuan)通(tong)過主(zhu)接(jie)觸器(qi)的(de)常閉點(dian)導通(tong)。如果(guo)主(zhu)電(dian)源(yuan)恢復(fu)正常，備用電(dian)源(yuan)斷(duan)開。

二、方案二

雙轉(zhuan)換(huan)觸點繼電器(qi)是雙轉(zhuan)換(huan)觸點，通電時，兩組觸點閉合(he)。斷電時兩組觸點閉合(he)。一個電器(qi)元件就可以完成。如(ru)果(guo)A路是單相220伏電源，繼電器(qi)的線圈(quan)電壓(ya)也選用交流220伏的

三、方案三

一個(ge)繼(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)兩個(ge)接(jie)(jie)(jie)觸(chu)器(qi)(qi)(qi)主電(dian)(dian)(dian)源的(de)(de)(de)接(jie)(jie)(jie)觸(chu)器(qi)(qi)(qi)線(xian)圈(quan)走繼(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)常(chang)開觸(chu)點(dian)(dian)(dian)，備用電(dian)(dian)(dian)源的(de)(de)(de)接(jie)(jie)(jie)觸(chu)器(qi)(qi)(qi)線(xian)圈(quan)走繼(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)常(chang)閉(bi)觸(chu)點(dian)(dian)(dian)。主線(xian)路(lu)(lu)有電(dian)(dian)(dian)的(de)(de)(de)時候(hou)，繼(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)吸(xi)合，常(chang)開觸(chu)點(dian)(dian)(dian)閉(bi)合，主線(xian)路(lu)(lu)導通。常(chang)閉(bi)觸(chu)點(dian)(dian)(dian)斷(duan)開，備用電(dian)(dian)(dian)源不工(gong)作。當主線(xian)路(lu)(lu)斷(duan)電(dian)(dian)(dian)的(de)(de)(de)時候(hou)，繼(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)也(ye)斷(duan)電(dian)(dian)(dian)。常(chang)開觸(chu)點(dian)(dian)(dian)恢復初始斷(duan)開狀態，主線(xian)路(lu)(lu)斷(duan)開。備用電(dian)(dian)(dian)路(lu)(lu)的(de)(de)(de)接(jie)(jie)(jie)觸(chu)器(qi)(qi)(qi)通過繼(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)常(chang)閉(bi)觸(chu)點(dian)(dian)(dian)開始工(gong)作。

雙電源(yuan)切(qie)換開(kai)關分PC級和(he)CB級，其結構大致一(yi)樣。PC級屬于隔(ge)離型的(de)，由(you)雙投刀開(kai)關加上操(cao)作機(ji)構構成(cheng)的(de)。CB級是斷路器保(bao)護型的(de)，由(you)兩個斷路器加操(cao)作機(ji)構組成(cheng)，有過(guo)載短路保(bao)護的(de)作用。

雙電(dian)(dian)源(yuan)(yuan)自(zi)(zi)(zi)動(dong)轉換開關控(kong)制(zhi)模(mo)式(shi)多樣化(hua)，支持手動(dong)、自(zi)(zi)(zi)動(dong)控(kong)制(zhi)模(mo)式(shi)，同時(shi)可(ke)(ke)選擇自(zi)(zi)(zi)投(tou)自(zi)(zi)(zi)復(fu)模(mo)式(shi)自(zi)(zi)(zi)動(dong)切換到備(bei)用電(dian)(dian)源(yuan)(yuan)，同時(shi)當主電(dian)(dian)源(yuan)(yuan)恢復(fu)供(gong)(gong)電(dian)(dian)，自(zi)(zi)(zi)動(dong)再切換回主電(dian)(dian)源(yuan)(yuan)供(gong)(gong)電(dian)(dian)。廣泛(fan)應用于住宅(zhai)、酒(jiu)店、寫字樓、消(xiao)防領域(yu)，其穩定、可(ke)(ke)靠、抗(kang)干擾能力強能夠(gou)確保(bao)供(gong)(gong)電(dian)(dian)的(de)可(ke)(ke)靠性與安(an)全性。
