三相變壓器原理

很多人可能不是很明白三相變壓器，其實三相變電器被廣泛用于工礦企業、郵電、紡織、鐵路、建筑工地、學校、醫院、賓館、國防、科研等部門的電子計算機的交流穩壓電源。同(tong)時也適用于電(dian)源電(dian)壓低、波動(dong)幅(fu)度(du)大(da)的低壓配電(dian)。這邊來(lai)介紹(shao)下(xia)他的原理和功能(neng)，可(ke)以一(yi)(yi)起來(lai)了解一(yi)(yi)下(xia)。

以上內容就是(shi)講解的相(xiang)關知(zhi)識，能夠更加(jia)深入(ru)地了解三(san)相(xiang)變壓器。

雖然變壓器有不(bu)同的(de)種類和結構形式，但(dan)它(ta)們的(de)基本工(gong)作原(yuan)理是相同的(de)，都是根據；動電(dian)生磁(ci)和磁(ci)動生電(dian)的(de)電(dian)磁(ci)感應原(yuan)理工(gong)作的(de)呢。
