低壓雙電源開關柜其原理是通過主用(yong)電源(yuan)和備用(yong)電源(yuan)的(de)(de)自(zi)動(dong)切(qie)換來實(shi)現(xian)的(de)(de)，當主電路(lu)(lu)停電或出現(xian)故障時，線路(lu)(lu)系統(tong)會自(zi)動(dong)切(qie)換至備用(yong)電源(yuan)線路(lu)(lu)。一般采用(yong)接(jie)觸器(qi)或繼(ji)電器(qi)實(shi)現(xian)自(zi)動(dong)切(qie)換，不(bu)同搭(da)配方案其工(gong)作原理也是不(bu)同的(de)(de)。下面介紹三(san)種配電方案的(de)(de)工(gong)作原理。

一、方案一

兩(liang)個接(jie)觸(chu)器實現切換備(bei)用電源(yuan)的(de)線圈走主(zhu)接(jie)觸(chu)器的(de)常(chang)閉點，主(zhu)電源(yuan)接(jie)觸(chu)器吸合主(zhu)電路導通(tong)。主(zhu)電源(yuan)斷電，備(bei)用電源(yuan)通(tong)過主(zhu)接(jie)觸(chu)器的(de)常(chang)閉點導通(tong)。如果主(zhu)電源(yuan)恢(hui)復正常(chang)，備(bei)用電源(yuan)斷開。

二、方案二

雙轉換觸(chu)點(dian)繼(ji)電(dian)(dian)(dian)器是(shi)雙轉換觸(chu)點(dian)，通電(dian)(dian)(dian)時(shi)，兩(liang)組(zu)(zu)觸(chu)點(dian)閉合。斷電(dian)(dian)(dian)時(shi)兩(liang)組(zu)(zu)觸(chu)點(dian)閉合。一個電(dian)(dian)(dian)器元件(jian)就可(ke)以完成(cheng)。如果A路是(shi)單相(xiang)220伏電(dian)(dian)(dian)源，繼(ji)電(dian)(dian)(dian)器的(de)線圈電(dian)(dian)(dian)壓也選(xuan)用交(jiao)流220伏的(de)

三、方案三

一(yi)個(ge)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)兩個(ge)接觸(chu)(chu)器(qi)(qi)主(zhu)電(dian)(dian)(dian)源的(de)接觸(chu)(chu)器(qi)(qi)線(xian)(xian)圈走繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)的(de)常開(kai)觸(chu)(chu)點，備用電(dian)(dian)(dian)源的(de)接觸(chu)(chu)器(qi)(qi)線(xian)(xian)圈走繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)的(de)常閉觸(chu)(chu)點。主(zhu)線(xian)(xian)路(lu)(lu)有電(dian)(dian)(dian)的(de)時候，繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)吸合(he)，常開(kai)觸(chu)(chu)點閉合(he)，主(zhu)線(xian)(xian)路(lu)(lu)導通(tong)。常閉觸(chu)(chu)點斷(duan)(duan)(duan)開(kai)，備用電(dian)(dian)(dian)源不工作(zuo)。當主(zhu)線(xian)(xian)路(lu)(lu)斷(duan)(duan)(duan)電(dian)(dian)(dian)的(de)時候，繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)也斷(duan)(duan)(duan)電(dian)(dian)(dian)。常開(kai)觸(chu)(chu)點恢復初(chu)始(shi)斷(duan)(duan)(duan)開(kai)狀態，主(zhu)線(xian)(xian)路(lu)(lu)斷(duan)(duan)(duan)開(kai)。備用電(dian)(dian)(dian)路(lu)(lu)的(de)接觸(chu)(chu)器(qi)(qi)通(tong)過繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)的(de)常閉觸(chu)(chu)點開(kai)始(shi)工作(zuo)。

雙(shuang)電源切換開關分PC級(ji)和CB級(ji)，其結構大致(zhi)一樣。PC級(ji)屬于隔離型的，由(you)雙(shuang)投刀開關加(jia)上操(cao)作機(ji)構構成(cheng)(cheng)的。CB級(ji)是斷路(lu)(lu)器保護型的，由(you)兩個斷路(lu)(lu)器加(jia)操(cao)作機(ji)構組成(cheng)(cheng)，有(you)過載短(duan)路(lu)(lu)保護的作用。

雙電源(yuan)(yuan)自(zi)(zi)動(dong)轉換開(kai)關控制模(mo)式(shi)多樣化，支(zhi)持手(shou)動(dong)、自(zi)(zi)動(dong)控制模(mo)式(shi)，同時可(ke)選擇自(zi)(zi)投(tou)自(zi)(zi)復(fu)模(mo)式(shi)自(zi)(zi)動(dong)切換到備(bei)用電源(yuan)(yuan)，同時當主(zhu)電源(yuan)(yuan)恢復(fu)供(gong)電，自(zi)(zi)動(dong)再切換回主(zhu)電源(yuan)(yuan)供(gong)電。廣泛應用于住宅、酒店(dian)、寫字樓(lou)、消防(fang)領域，其穩定(ding)、可(ke)靠(kao)、抗(kang)干擾能力強能夠(gou)確保供(gong)電的可(ke)靠(kao)性與安全性。
