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(ye)適(shi)用于(yu)電源(yuan)電壓低(di)、波動幅(fu)度(du)大(da)的(de)低(di)壓配電。這邊(bian)來介紹下他的(de)原理和功(gong)能，可(ke)以(yi)一(yi)起來了解一(yi)下。

三(san)(san)(san)(san)相(xiang)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)是(shi)3個(ge)相(xiang)同的(de)(de)(de)容量單相(xiang)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)組合。它(ta)(ta)有三(san)(san)(san)(san)個(ge)鐵(tie)(tie)芯(xin)(xin)柱(zhu)，每(mei)個(ge)鐵(tie)(tie)芯(xin)(xin)柱(zhu)都繞(rao)著同一(yi)相(xiang)的(de)(de)(de)2個(ge)線圈，一(yi)個(ge)是(shi)高(gao)壓(ya)(ya)(ya)線圈，另一(yi)個(ge)是(shi)低壓(ya)(ya)(ya)線圈。三(san)(san)(san)(san)相(xiang)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)是(shi)產生幅(fu)值相(xiang)等、頻率相(xiang)等、相(xiang)位互差(cha)120°電(dian)(dian)(dian)勢的(de)(de)(de)發電(dian)(dian)(dian)機(ji)稱為三(san)(san)(san)(san)相(xiang)發電(dian)(dian)(dian)機(ji)；以(yi)三(san)(san)(san)(san)相(xiang)發電(dian)(dian)(dian)機(ji)作(zuo)(zuo)為電(dian)(dian)(dian)源，稱為三(san)(san)(san)(san)相(xiang)電(dian)(dian)(dian)源；以(yi)三(san)(san)(san)(san)相(xiang)電(dian)(dian)(dian)源供電(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)路(lu)(lu)，稱為三(san)(san)(san)(san)相(xiang)電(dian)(dian)(dian)路(lu)(lu)。U、V、W稱為三(san)(san)(san)(san)相(xiang)，相(xiang)與(yu)相(xiang)之間的(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)是(shi)線電(dian)(dian)(dian)壓(ya)(ya)(ya)，電(dian)(dian)(dian)壓(ya)(ya)(ya)為380V.相(xiang)與(yu)中心線之間稱為相(xiang)電(dian)(dian)(dian)壓(ya)(ya)(ya)，電(dian)(dian)(dian)壓(ya)(ya)(ya)是(shi)220V.三(san)(san)(san)(san)相(xiang)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)工作(zuo)(zuo)原(yuan)(yuan)理：變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)基本工作(zuo)(zuo)原(yuan)(yuan)理是(shi)電(dian)(dian)(dian)磁(ci)(ci)感應(ying)原(yuan)(yuan)理。當交(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)壓(ya)(ya)(ya)加到一(yi)次側繞(rao)組后(hou)交(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)流(liu)(liu)(liu)流(liu)(liu)(liu)入該繞(rao)組就產生勵磁(ci)(ci)作(zuo)(zuo)用，在(zai)鐵(tie)(tie)芯(xin)(xin)中產生交(jiao)變(bian)(bian)(bian)的(de)(de)(de)磁(ci)(ci)通，這個(ge)交(jiao)變(bian)(bian)(bian)磁(ci)(ci)通不(bu)(bu)僅穿過一(yi)次側繞(rao)組，同時(shi)也(ye)穿過二次側繞(rao)組，它(ta)(ta)分別在(zai)兩個(ge)繞(rao)組中引起感應(ying)電(dian)(dian)(dian)動勢。這時(shi)如果二次側與(yu)外電(dian)(dian)(dian)路(lu)(lu)的(de)(de)(de)負載(zai)接通，便有交(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)流(liu)(liu)(liu)流(liu)(liu)(liu)出(chu)，于是(shi)輸(shu)出(chu)電(dian)(dian)(dian)能。變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)有不(bu)(bu)同的(de)(de)(de)使用條件、安裝場(chang)所，有不(bu)(bu)同的(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)等級(ji)和(he)容量級(ji)別，有不(bu)(bu)同的(de)(de)(de)結(jie)構形式(shi)和(he)冷卻方式(shi)，所以(yi)應(ying)按不(bu)(bu)同原(yuan)(yuan)則進行分類。變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)分為電(dian)(dian)(dian)力變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)（又(you)可分為升壓(ya)(ya)(ya)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)、降壓(ya)(ya)(ya)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)、配電(dian)(dian)(dian)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)、廠用變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)等）、特種變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)（電(dian)(dian)(dian)爐變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)、整流(liu)(liu)(liu)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)焊(han)變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)等）、儀用互感器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)（電(dian)(dian)(dian)壓(ya)(ya)(ya)互感器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)流(liu)(liu)(liu)互感器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)）、試(shi)驗(yan)用的(de)(de)(de)高(gao)奪變(bian)(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)和(he)調壓(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)等。

以上內容(rong)就是講(jiang)解(jie)(jie)的相關(guan)知識，能夠更加(jia)深入(ru)地了解(jie)(jie)三相變壓器(qi)。

雖然(ran)變(bian)壓器有不同的(de)種(zhong)類和(he)(he)結構形(xing)式，但它們的(de)基本(ben)工作原理是(shi)(shi)相同的(de)，都是(shi)(shi)根(gen)據；動電生磁和(he)(he)磁動生電的(de)電磁感應原理工作的(de)呢。
