380伏三(san)相(xiang)四線電(dian)(dian)(dian)(dian)路(lu)中，任意兩根火線之間的電(dian)(dian)(dian)(dian)壓都是380伏，任意一根火線與零線之間都可(ke)以(yi)組成(cheng)220伏。這個系統可(ke)以(yi)形成(cheng)三(san)種電(dian)(dian)(dian)(dian)源(yuan)(yuan)：即單(dan)相(xiang)220伏電(dian)(dian)(dian)(dian)源(yuan)(yuan)，單(dan)相(xiang)380伏電(dian)(dian)(dian)(dian)源(yuan)(yuan)，三(san)相(xiang)380伏電(dian)(dian)(dian)(dian)源(yuan)(yuan)，第 I 種家用比較多，第三(san)種工廠(chang)里電(dian)(dian)(dian)(dian)機(ji)類(lei)用得(de)多，第二種用得(de)少，只有交流電(dian)(dian)(dian)(dian)焊機(ji)經常用到單(dan)相(xiang)380伏電(dian)(dian)(dian)(dian)源(yuan)(yuan)。
