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。同時也適用于電(dian)源電(dian)壓低、波動幅度大的(de)低壓配電(dian)。這邊(bian)來(lai)介紹下他的(de)原理和功(gong)能，可以一起來(lai)了解一下。

三(san)相(xiang)(xiang)(xiang)(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)是3個(ge)相(xiang)(xiang)(xiang)(xiang)同(tong)(tong)的(de)(de)(de)容量單相(xiang)(xiang)(xiang)(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)組(zu)(zu)合(he)。它有(you)(you)(you)三(san)個(ge)鐵芯柱，每個(ge)鐵芯柱都(dou)繞著同(tong)(tong)一(yi)相(xiang)(xiang)(xiang)(xiang)的(de)(de)(de)2個(ge)線(xian)圈，一(yi)個(ge)是高(gao)壓(ya)(ya)(ya)(ya)線(xian)圈，另(ling)一(yi)個(ge)是低(di)壓(ya)(ya)(ya)(ya)線(xian)圈。三(san)相(xiang)(xiang)(xiang)(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)是產(chan)(chan)生幅(fu)值(zhi)相(xiang)(xiang)(xiang)(xiang)等(deng)、頻率相(xiang)(xiang)(xiang)(xiang)等(deng)、相(xiang)(xiang)(xiang)(xiang)位互差120°電(dian)(dian)(dian)(dian)勢(shi)的(de)(de)(de)發(fa)(fa)電(dian)(dian)(dian)(dian)機稱(cheng)為(wei)三(san)相(xiang)(xiang)(xiang)(xiang)發(fa)(fa)電(dian)(dian)(dian)(dian)機；以三(san)相(xiang)(xiang)(xiang)(xiang)發(fa)(fa)電(dian)(dian)(dian)(dian)機作為(wei)電(dian)(dian)(dian)(dian)源，稱(cheng)為(wei)三(san)相(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)(dian)源；以三(san)相(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)(dian)源供電(dian)(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)(dian)路(lu)(lu)，稱(cheng)為(wei)三(san)相(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)(dian)路(lu)(lu)。U、V、W稱(cheng)為(wei)三(san)相(xiang)(xiang)(xiang)(xiang)，相(xiang)(xiang)(xiang)(xiang)與相(xiang)(xiang)(xiang)(xiang)之(zhi)間(jian)的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)是線(xian)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)為(wei)380V.相(xiang)(xiang)(xiang)(xiang)與中心線(xian)之(zhi)間(jian)稱(cheng)為(wei)相(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)是220V.三(san)相(xiang)(xiang)(xiang)(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)工作原(yuan)(yuan)(yuan)理(li)：變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)基(ji)本(ben)工作原(yuan)(yuan)(yuan)理(li)是電(dian)(dian)(dian)(dian)磁(ci)感(gan)(gan)應原(yuan)(yuan)(yuan)理(li)。當交(jiao)(jiao)(jiao)流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)加到一(yi)次(ci)側(ce)繞組(zu)(zu)后交(jiao)(jiao)(jiao)流(liu)電(dian)(dian)(dian)(dian)流(liu)流(liu)入該繞組(zu)(zu)就(jiu)產(chan)(chan)生勵磁(ci)作用，在(zai)鐵芯中產(chan)(chan)生交(jiao)(jiao)(jiao)變(bian)(bian)(bian)(bian)的(de)(de)(de)磁(ci)通(tong)，這個(ge)交(jiao)(jiao)(jiao)變(bian)(bian)(bian)(bian)磁(ci)通(tong)不(bu)僅(jin)穿(chuan)過(guo)一(yi)次(ci)側(ce)繞組(zu)(zu)，同(tong)(tong)時(shi)也穿(chuan)過(guo)二(er)(er)次(ci)側(ce)繞組(zu)(zu)，它分別(bie)在(zai)兩個(ge)繞組(zu)(zu)中引起感(gan)(gan)應電(dian)(dian)(dian)(dian)動勢(shi)。這時(shi)如果二(er)(er)次(ci)側(ce)與外電(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)(de)負載接通(tong)，便有(you)(you)(you)交(jiao)(jiao)(jiao)流(liu)電(dian)(dian)(dian)(dian)流(liu)流(liu)出(chu)，于是輸出(chu)電(dian)(dian)(dian)(dian)能。變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)有(you)(you)(you)不(bu)同(tong)(tong)的(de)(de)(de)使用條(tiao)件、安裝(zhuang)場所，有(you)(you)(you)不(bu)同(tong)(tong)的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)等(deng)級和容量級別(bie)，有(you)(you)(you)不(bu)同(tong)(tong)的(de)(de)(de)結(jie)構形式和冷卻(que)方式，所以應按不(bu)同(tong)(tong)原(yuan)(yuan)(yuan)則進行分類。變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)分為(wei)電(dian)(dian)(dian)(dian)力變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)（又可(ke)分為(wei)升(sheng)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)、降壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)、配電(dian)(dian)(dian)(dian)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)、廠用變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)等(deng)）、特(te)種變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)（電(dian)(dian)(dian)(dian)爐(lu)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)、整流(liu)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)焊(han)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)等(deng)）、儀(yi)用互感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)（電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)互感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)流(liu)互感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)）、試(shi)驗用的(de)(de)(de)高(gao)奪變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)和調(diao)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)等(deng)。

雖(sui)然變(bian)壓器有不同(tong)的(de)種(zhong)類和(he)結構(gou)形式，但它們的(de)基本(ben)工作原理是相同(tong)的(de)，都是根據；動電(dian)(dian)生磁和(he)磁動生電(dian)(dian)的(de)電(dian)(dian)磁感應(ying)原理工作的(de)呢(ni)。
