變壓器行業簡介

變壓器的原理

變壓(ya)(ya)器的(de)(de)原(yuan)理(li)并不(bu)復雜，它利用了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)感應原(yuan)理(li)。當其中一(yi)塊導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)體(ti)有(you)(you)一(yi)些不(bu)定量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)通(tong)過(guo)，便會(hui)產(chan)(chan)(chan)生變動(dong)的(de)(de)磁(ci)(ci)場。根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)的(de)(de)互(hu)感原(yuan)理(li)，這(zhe)變動(dong)的(de)(de)磁(ci)(ci)場會(hui)使(shi)第二塊導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)體(ti)產(chan)(chan)(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)勢差。假(jia)如第二塊導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)體(ti)是(shi)一(yi)條閉合(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路的(de)(de)一(yi)部份(fen)，那么該(gai)閉合(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路便會(hui)產(chan)(chan)(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力于是(shi)得以(yi)傳送。在通(tong)用的(de)(de)變壓(ya)(ya)器中，有(you)(you)關的(de)(de)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)體(ti)是(shi)由(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)組成(cheng)線(xian)(xian)(xian)圈，因為線(xian)(xian)(xian)圈所產(chan)(chan)(chan)生的(de)(de)磁(ci)(ci)場要比一(yi)條筆(bi)直的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)大得多。當初(chu)級線(xian)(xian)(xian)圈中通(tong)有(you)(you)交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)時，鐵(tie)芯中便產(chan)(chan)(chan)生交流(liu)(liu)磁(ci)(ci)通(tong)，使(shi)次級線(xian)(xian)(xian)圈中感應出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)。初(chu)級線(xian)(xian)(xian)圈、次級線(xian)(xian)(xian)圈的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)VS，VP和兩(liang)者的(de)(de)繞線(xian)(xian)(xian)的(de)(de)匝數NS，NP之間有(you)(you)正比的(de)(de)關系。

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(de)(de)這個性(xing)質使它成為轉(zhuan)換電(dian)壓(ya)的(de)(de)重要(yao)設備。由于(yu)變壓(ya)器(qi)遵守(shou)這兩(liang)(liang)條定律，它不(bu)會是(shi)放(fang)大器(qi)。如果處在(zai)變壓(ya)器(qi)兩(liang)(liang)方的(de)(de)電(dian)壓(ya)有所(suo)不(bu)同(tong)(tong)，那么(me)流經(jing)變壓(ya)器(qi)兩(liang)(liang)方的(de)(de)電(dian)流也會不(bu)同(tong)(tong)，而兩(liang)(liang)者的(de)(de)差(cha)距(ju)則成反比。

干式變壓器和油浸式變壓器的區別

干式變(bian)壓(ya)(ya)器能(neng)直(zhi)接(jie)看到(dao)(dao)(dao)鐵芯和線(xian)圈(quan)，大多(duo)使用硅橡膠套管，適(shi)用于(yu)配電用，容量(liang)大都在1600KVA以下(xia)，電壓(ya)(ya)在10KV以下(xia)，也(ye)有個別(bie)做到(dao)(dao)(dao)35KV電壓(ya)(ya)等級(ji)(ji)的。油式變(bian)壓(ya)(ya)器只能(neng)看到(dao)(dao)(dao)變(bian)壓(ya)(ya)器的外殼，大部分(fen)使用瓷套管，可用于(yu)高壓(ya)(ya)電路，可以從小(xiao)到(dao)(dao)(dao)大做到(dao)(dao)(dao)全部容量(liang)，電壓(ya)(ya)等級(ji)(ji)也(ye)做到(dao)(dao)(dao)了所有電壓(ya)(ya)。

變壓器的等級怎么劃分

變(bian)壓器(qi)的(de)(de)電壓等(deng)(deng)(deng)級(ji)是固定的(de)(de)，常見的(de)(de)有1000KV、750KV、500KV、330KV、220KV、110KV、66KV、35KV、20KV、10KV、6KV等(deng)(deng)(deng)等(deng)(deng)(deng)。變(bian)壓器(qi)的(de)(de)容量等(deng)(deng)(deng)級(ji)按照R10優先系數來計算的(de)(de)，可分為小型(xing)變(bian)壓器(qi)、中型(xing)變(bian)壓器(qi)、大型(xing)變(bian)壓器(qi)、特(te)大型(xing)變(bian)壓器(qi)這四個等(deng)(deng)(deng)級(ji)。
