style="text-indent:25px">當(dāng)變壓器的初級(jí)繞組通電后，線圈所產(chǎn)生的磁通在鐵心流動(dòng)，因?yàn)殍F心本身也是導(dǎo)體，在垂直于磁力線的平面上就會(huì)感應(yīng)電勢(shì)，這個(gè)電勢(shì)在鐵心的斷面上形成閉合回路并產(chǎn)生電流，好象一個(gè)旋渦所以稱為“渦流”。這個(gè)“渦流”使變壓器的損耗增加，并且使變壓器的鐵心發(fā)熱變壓器的溫升增加。由“渦流”所產(chǎn)生的損耗我們稱為“鐵損”。另外要繞制變壓器需要用大量的銅線，這些銅導(dǎo)線存在著電阻，電流流過時(shí)這電阻會(huì)消耗一定的功率，這部分損耗往往變成熱量而消耗，我們稱這種損耗為“銅損”。所以變壓器的溫升主要由鐵損和銅損產(chǎn)生的。深圳市展榮新精密電子有限公司目前專注于生產(chǎn)制造電子變壓器元器件測(cè)試儀這類設(shè)備。</p><div
