互感器行業簡介

一、互感器的作用是什么

互(hu)感(gan)(gan)器是(shi)(shi)電(dian)(dian)(dian)(dian)流(liu)互(hu)感(gan)(gan)器和(he)電(dian)(dian)(dian)(dian)壓(ya)互(hu)感(gan)(gan)器的統(tong)稱(cheng)，又被(bei)(bei)稱(cheng)為(wei)儀(yi)用變壓(ya)器。互(hu)感(gan)(gan)器被(bei)(bei)廣泛應用于(yu)供電(dian)(dian)(dian)(dian)系統(tong)中向測量(liang)儀(yi)表(biao)和(he)繼(ji)電(dian)(dian)(dian)(dian)器的電(dian)(dian)(dian)(dian)壓(ya)線圈(quan)或電(dian)(dian)(dian)(dian)流(liu)線圈(quan)供電(dian)(dian)(dian)(dian)。互(hu)感(gan)(gan)器的作用是(shi)(shi)將交流(liu)電(dian)(dian)(dian)(dian)壓(ya)和(he)大電(dian)(dian)(dian)(dian)流(liu)按比例降到可以(yi)用儀(yi)表(biao)直接(jie)(jie)測量(liang)的數值，便(bian)于(yu)儀(yi)表(biao)直接(jie)(jie)測量(liang)，同(tong)時為(wei)繼(ji)電(dian)(dian)(dian)(dian)保護和(he)自動裝置提供電(dian)(dian)(dian)(dian)源。

二、互感器怎么看倍數

電(dian)(dian)(dian)流(liu)(liu)互感(gan)器(qi)(qi)的(de)倍率與互感(gan)器(qi)(qi)的(de)變比有關，在互感(gan)器(qi)(qi)銘牌上(shang)有標識。電(dian)(dian)(dian)表的(de)倍數=電(dian)(dian)(dian)流(liu)(liu)互感(gan)器(qi)(qi)變比乘以(yi)電(dian)(dian)(dian)壓互感(gan)器(qi)(qi)變比，當沒有電(dian)(dian)(dian)壓互感(gan)器(qi)(qi)，其變比按1計算，例如，一次額定電(dian)(dian)(dian)流(liu)(liu)為100A，二次額定電(dian)(dian)(dian)流(liu)(liu)為5A，那么(me)該互感(gan)器(qi)(qi)的(de)倍率為100/5=20。

三、互感器的原理是什么

電(dian)(dian)流互(hu)感(gan)(gan)器(qi)的(de)原(yuan)理是依據(ju)電(dian)(dian)磁感(gan)(gan)應原(yuan)理，它的(de)一次(ci)繞組經常有線路(lu)(lu)的(de)全(quan)部電(dian)(dian)流流過，電(dian)(dian)流互(hu)感(gan)(gan)器(qi)在工(gong)作(zuo)時(shi)，它的(de)2次(ci)回(hui)路(lu)(lu)始終是閉合(he)的(de)，因(yin)此測(ce)量儀表和保護回(hui)路(lu)(lu)串聯(lian)線圈(quan)的(de)阻(zu)抗很小，電(dian)(dian)流互(hu)感(gan)(gan)器(qi)的(de)工(gong)作(zuo)狀態接近短(duan)路(lu)(lu)。

四、互感器的規格

互感器的規格通常指的是互感器變比的規格，電流互感器變比的規格很多：50/5，75/5，100/5，150/5，200/5，250/5，300/5，400/5，600/5，800/5，1000/5，1200/5，2000/5，4000/5，選購互感器品牌時注(zhu)意根據(ju)需求選擇合適的規格，安全性(xing)能比較要(yao)強。
