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(yu)電(dian)(dian)源電(dian)(dian)壓(ya)低、波動幅(fu)度大的(de)低壓(ya)配(pei)電(dian)(dian)。這邊來(lai)介紹下他的(de)原理和功能，可以一起來(lai)了解(jie)一下。

三(san)(san)相(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)是3個(ge)相(xiang)同(tong)(tong)的(de)(de)(de)(de)(de)容量(liang)單(dan)相(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)組合。它有三(san)(san)個(ge)鐵(tie)芯柱，每個(ge)鐵(tie)芯柱都繞(rao)著同(tong)(tong)一(yi)相(xiang)的(de)(de)(de)(de)(de)2個(ge)線(xian)(xian)圈(quan)，一(yi)個(ge)是高壓(ya)(ya)(ya)(ya)(ya)(ya)線(xian)(xian)圈(quan)，另一(yi)個(ge)是低壓(ya)(ya)(ya)(ya)(ya)(ya)線(xian)(xian)圈(quan)。三(san)(san)相(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)是產(chan)生幅值相(xiang)等(deng)、頻(pin)率(lv)相(xiang)等(deng)、相(xiang)位互(hu)(hu)差120°電(dian)(dian)勢的(de)(de)(de)(de)(de)發(fa)電(dian)(dian)機(ji)稱(cheng)為(wei)(wei)三(san)(san)相(xiang)發(fa)電(dian)(dian)機(ji)；以(yi)(yi)三(san)(san)相(xiang)發(fa)電(dian)(dian)機(ji)作(zuo)為(wei)(wei)電(dian)(dian)源(yuan)(yuan)，稱(cheng)為(wei)(wei)三(san)(san)相(xiang)電(dian)(dian)源(yuan)(yuan)；以(yi)(yi)三(san)(san)相(xiang)電(dian)(dian)源(yuan)(yuan)供電(dian)(dian)的(de)(de)(de)(de)(de)電(dian)(dian)路(lu)(lu)，稱(cheng)為(wei)(wei)三(san)(san)相(xiang)電(dian)(dian)路(lu)(lu)。U、V、W稱(cheng)為(wei)(wei)三(san)(san)相(xiang)，相(xiang)與相(xiang)之間的(de)(de)(de)(de)(de)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)是線(xian)(xian)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)，電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)為(wei)(wei)380V.相(xiang)與中(zhong)心(xin)線(xian)(xian)之間稱(cheng)為(wei)(wei)相(xiang)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)，電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)是220V.三(san)(san)相(xiang)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)工(gong)作(zuo)原(yuan)(yuan)理：變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)基本工(gong)作(zuo)原(yuan)(yuan)理是電(dian)(dian)磁感(gan)應原(yuan)(yuan)理。當(dang)交(jiao)(jiao)流(liu)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)加到一(yi)次(ci)側繞(rao)組后交(jiao)(jiao)流(liu)電(dian)(dian)流(liu)流(liu)入該繞(rao)組就產(chan)生勵磁作(zuo)用，在鐵(tie)芯中(zhong)產(chan)生交(jiao)(jiao)變(bian)(bian)(bian)(bian)的(de)(de)(de)(de)(de)磁通，這(zhe)個(ge)交(jiao)(jiao)變(bian)(bian)(bian)(bian)磁通不僅穿過一(yi)次(ci)側繞(rao)組，同(tong)(tong)時也穿過二次(ci)側繞(rao)組，它分(fen)別在兩(liang)個(ge)繞(rao)組中(zhong)引起感(gan)應電(dian)(dian)動勢。這(zhe)時如(ru)果(guo)二次(ci)側與外電(dian)(dian)路(lu)(lu)的(de)(de)(de)(de)(de)負載接通，便(bian)有交(jiao)(jiao)流(liu)電(dian)(dian)流(liu)流(liu)出，于是輸出電(dian)(dian)能。變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)有不同(tong)(tong)的(de)(de)(de)(de)(de)使用條(tiao)件、安裝(zhuang)場所(suo)(suo)，有不同(tong)(tong)的(de)(de)(de)(de)(de)電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)等(deng)級(ji)和(he)容量(liang)級(ji)別，有不同(tong)(tong)的(de)(de)(de)(de)(de)結構(gou)形式和(he)冷卻方(fang)式，所(suo)(suo)以(yi)(yi)應按不同(tong)(tong)原(yuan)(yuan)則進行分(fen)類(lei)。變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)分(fen)為(wei)(wei)電(dian)(dian)力變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)（又可分(fen)為(wei)(wei)升壓(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)、降壓(ya)(ya)(ya)(ya)(ya)(ya)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)、配電(dian)(dian)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)、廠用變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)等(deng)）、特種變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)（電(dian)(dian)爐變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)、整流(liu)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)焊變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)等(deng)）、儀用互(hu)(hu)感(gan)器(qi)(qi)(qi)(qi)(qi)（電(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)互(hu)(hu)感(gan)器(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)流(liu)互(hu)(hu)感(gan)器(qi)(qi)(qi)(qi)(qi)）、試驗(yan)用的(de)(de)(de)(de)(de)高奪(duo)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)和(he)調(diao)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)(qi)等(deng)。

雖然變壓器有不(bu)同(tong)的(de)種類和結(jie)構形式，但它(ta)們的(de)基本工作(zuo)原理是相(xiang)同(tong)的(de)，都(dou)是根據；動電生磁(ci)(ci)和磁(ci)(ci)動生電的(de)電磁(ci)(ci)感應原理工作(zuo)的(de)呢。
