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(shi)也適用于(yu)電源電壓低(di)、波動幅度大的低(di)壓配電。這邊來(lai)介紹下他(ta)的原理和(he)功能(neng)，可以一起來(lai)了解一下。

三(san)(san)相(xiang)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)是3個(ge)(ge)(ge)相(xiang)同(tong)(tong)(tong)(tong)的(de)(de)(de)(de)容量單相(xiang)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)的(de)(de)(de)(de)組(zu)合。它有三(san)(san)個(ge)(ge)(ge)鐵芯柱，每個(ge)(ge)(ge)鐵芯柱都繞(rao)著同(tong)(tong)(tong)(tong)一(yi)(yi)(yi)相(xiang)的(de)(de)(de)(de)2個(ge)(ge)(ge)線(xian)圈(quan)，一(yi)(yi)(yi)個(ge)(ge)(ge)是高(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)線(xian)圈(quan)，另(ling)一(yi)(yi)(yi)個(ge)(ge)(ge)是低壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)線(xian)圈(quan)。三(san)(san)相(xiang)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)是產(chan)(chan)生幅值(zhi)相(xiang)等、頻率相(xiang)等、相(xiang)位互(hu)差120°電(dian)(dian)(dian)(dian)(dian)(dian)勢的(de)(de)(de)(de)發電(dian)(dian)(dian)(dian)(dian)(dian)機稱(cheng)為(wei)三(san)(san)相(xiang)發電(dian)(dian)(dian)(dian)(dian)(dian)機；以三(san)(san)相(xiang)發電(dian)(dian)(dian)(dian)(dian)(dian)機作(zuo)為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)源，稱(cheng)為(wei)三(san)(san)相(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)源；以三(san)(san)相(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)，稱(cheng)為(wei)三(san)(san)相(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)。U、V、W稱(cheng)為(wei)三(san)(san)相(xiang)，相(xiang)與(yu)相(xiang)之間(jian)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)是線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)為(wei)380V.相(xiang)與(yu)中(zhong)心線(xian)之間(jian)稱(cheng)為(wei)相(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)是220V.三(san)(san)相(xiang)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)工作(zuo)原(yuan)理：變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)的(de)(de)(de)(de)基本工作(zuo)原(yuan)理是電(dian)(dian)(dian)(dian)(dian)(dian)磁感(gan)(gan)(gan)應(ying)原(yuan)理。當交(jiao)(jiao)(jiao)(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)加到一(yi)(yi)(yi)次(ci)(ci)側繞(rao)組(zu)后交(jiao)(jiao)(jiao)(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)流流入該(gai)繞(rao)組(zu)就產(chan)(chan)生勵磁作(zuo)用(yong)，在鐵芯中(zhong)產(chan)(chan)生交(jiao)(jiao)(jiao)(jiao)變(bian)(bian)的(de)(de)(de)(de)磁通，這個(ge)(ge)(ge)交(jiao)(jiao)(jiao)(jiao)變(bian)(bian)磁通不僅穿(chuan)(chuan)過(guo)一(yi)(yi)(yi)次(ci)(ci)側繞(rao)組(zu)，同(tong)(tong)(tong)(tong)時也穿(chuan)(chuan)過(guo)二(er)次(ci)(ci)側繞(rao)組(zu)，它分別在兩個(ge)(ge)(ge)繞(rao)組(zu)中(zhong)引起感(gan)(gan)(gan)應(ying)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)勢。這時如果二(er)次(ci)(ci)側與(yu)外(wai)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)(de)負(fu)載接通，便(bian)有交(jiao)(jiao)(jiao)(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)流流出，于是輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)能。變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)有不同(tong)(tong)(tong)(tong)的(de)(de)(de)(de)使用(yong)條件、安(an)裝場所(suo)，有不同(tong)(tong)(tong)(tong)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)等級和(he)容量級別，有不同(tong)(tong)(tong)(tong)的(de)(de)(de)(de)結構形(xing)式和(he)冷(leng)卻方式，所(suo)以應(ying)按(an)不同(tong)(tong)(tong)(tong)原(yuan)則進行(xing)分類(lei)。變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)分為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)（又可分為(wei)升壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)、降(jiang)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)、配電(dian)(dian)(dian)(dian)(dian)(dian)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)、廠用(yong)變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)等）、特種變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)（電(dian)(dian)(dian)(dian)(dian)(dian)爐變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)、整流變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)焊變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)等）、儀用(yong)互(hu)感(gan)(gan)(gan)器(qi)（電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)互(hu)感(gan)(gan)(gan)器(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)流互(hu)感(gan)(gan)(gan)器(qi)）、試(shi)驗(yan)用(yong)的(de)(de)(de)(de)高(gao)(gao)奪變(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)和(he)調壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)等。

以(yi)上(shang)內容就是講解(jie)的相(xiang)關(guan)知識，能夠更加深入地了解(jie)三相(xiang)變(bian)壓器。

雖然變(bian)壓器有(you)不同的(de)(de)種(zhong)類(lei)和結構形式，但它們的(de)(de)基本工(gong)作原理是(shi)(shi)相同的(de)(de)，都是(shi)(shi)根據(ju)；動電生(sheng)磁(ci)和磁(ci)動生(sheng)電的(de)(de)電磁(ci)感應原理工(gong)作的(de)(de)呢。
