變壓器行業簡介

變壓器的原理

變壓(ya)器的(de)(de)原理并(bing)不復雜(za)，它利用(yong)了(le)電(dian)(dian)(dian)磁(ci)感(gan)(gan)應(ying)原理。當其中(zhong)一(yi)塊導電(dian)(dian)(dian)體有一(yi)些不定(ding)量的(de)(de)電(dian)(dian)(dian)流(liu)(liu)通過，便(bian)會(hui)產生(sheng)變動(dong)的(de)(de)磁(ci)場。根(gen)據電(dian)(dian)(dian)磁(ci)的(de)(de)互感(gan)(gan)原理，這變動(dong)的(de)(de)磁(ci)場會(hui)使(shi)第二塊導電(dian)(dian)(dian)體產生(sheng)電(dian)(dian)(dian)勢差。假如第二塊導電(dian)(dian)(dian)體是一(yi)條(tiao)閉(bi)(bi)合(he)電(dian)(dian)(dian)路的(de)(de)一(yi)部份(fen)，那么(me)該閉(bi)(bi)合(he)電(dian)(dian)(dian)路便(bian)會(hui)產生(sheng)電(dian)(dian)(dian)流(liu)(liu)。電(dian)(dian)(dian)力于是得(de)以傳送(song)。在通用(yong)的(de)(de)變壓(ya)器中(zhong)，有關(guan)(guan)的(de)(de)導電(dian)(dian)(dian)體是由電(dian)(dian)(dian)線(xian)(xian)組成線(xian)(xian)圈(quan)(quan)，因為線(xian)(xian)圈(quan)(quan)所產生(sheng)的(de)(de)磁(ci)場要比(bi)一(yi)條(tiao)筆直(zhi)的(de)(de)電(dian)(dian)(dian)線(xian)(xian)大得(de)多。當初級(ji)(ji)線(xian)(xian)圈(quan)(quan)中(zhong)通有交流(liu)(liu)電(dian)(dian)(dian)流(liu)(liu)時，鐵芯中(zhong)便(bian)產生(sheng)交流(liu)(liu)磁(ci)通，使(shi)次級(ji)(ji)線(xian)(xian)圈(quan)(quan)中(zhong)感(gan)(gan)應(ying)出電(dian)(dian)(dian)壓(ya)。初級(ji)(ji)線(xian)(xian)圈(quan)(quan)、次級(ji)(ji)線(xian)(xian)圈(quan)(quan)的(de)(de)電(dian)(dian)(dian)壓(ya)VS，VP和兩(liang)者的(de)(de)繞線(xian)(xian)的(de)(de)匝數NS，NP之間有正比(bi)的(de)(de)關(guan)(guan)系。

至于變壓器兩方之間的電流或電壓比例，則取決于兩方電路線圈的圈數。圈數較多的一方電壓較高但電流較小，反之亦然。如果撇除泄漏等因素，變壓器兩方的電壓比例相等于兩方的線圈圈數比例，亦即電壓與圈數成正比。因此可以減小或者增加原線圈和副線圈的匝數比，從而升高或者降低電壓，變壓器品牌產品的這(zhe)(zhe)個性質使它成(cheng)(cheng)為轉換電(dian)壓(ya)(ya)的重要設備(bei)。由(you)于變壓(ya)(ya)器遵守(shou)這(zhe)(zhe)兩(liang)條定律(lv)，它不(bu)會(hui)是(shi)放大器。如果處在變壓(ya)(ya)器兩(liang)方的電(dian)壓(ya)(ya)有所不(bu)同，那(nei)么流(liu)經變壓(ya)(ya)器兩(liang)方的電(dian)流(liu)也會(hui)不(bu)同，而兩(liang)者的差距則成(cheng)(cheng)反比。

干式變壓器和油浸式變壓器的區別

干式變(bian)壓(ya)器能(neng)(neng)直接(jie)看(kan)(kan)到鐵芯和線圈(quan)，大(da)(da)多使用(yong)(yong)硅(gui)橡膠套管(guan)，適用(yong)(yong)于(yu)配電(dian)(dian)(dian)用(yong)(yong)，容(rong)量大(da)(da)都在1600KVA以下，電(dian)(dian)(dian)壓(ya)在10KV以下，也(ye)有個別做(zuo)到35KV電(dian)(dian)(dian)壓(ya)等級的。油式變(bian)壓(ya)器只能(neng)(neng)看(kan)(kan)到變(bian)壓(ya)器的外殼，大(da)(da)部(bu)分使用(yong)(yong)瓷(ci)套管(guan)，可(ke)用(yong)(yong)于(yu)高壓(ya)電(dian)(dian)(dian)路，可(ke)以從小到大(da)(da)做(zuo)到全(quan)部(bu)容(rong)量，電(dian)(dian)(dian)壓(ya)等級也(ye)做(zuo)到了(le)所有電(dian)(dian)(dian)壓(ya)。

變壓器的等級怎么劃分

變(bian)壓(ya)(ya)器(qi)的(de)電(dian)壓(ya)(ya)等(deng)級(ji)是固定的(de)，常見的(de)有1000KV、750KV、500KV、330KV、220KV、110KV、66KV、35KV、20KV、10KV、6KV等(deng)等(deng)。變(bian)壓(ya)(ya)器(qi)的(de)容量(liang)等(deng)級(ji)按(an)照R10優先系(xi)數來計(ji)算的(de)，可分為小型變(bian)壓(ya)(ya)器(qi)、中型變(bian)壓(ya)(ya)器(qi)、大型變(bian)壓(ya)(ya)器(qi)、特大型變(bian)壓(ya)(ya)器(qi)這四個等(deng)級(ji)。
