電(dian)(dian)(dian)流互(hu)(hu)(hu)(hu)感(gan)器(qi)(qi)(qi)的(de)(de)優(you)點(dian)是可以根據(ju)負(fu)荷電(dian)(dian)(dian)流變(bian)(bian)(bian)(bian)比(bi)，調換(huan)(huan)二(er)次(ci)(ci)接線端(duan)子的(de)(de)接線來改變(bian)(bian)(bian)(bian)變(bian)(bian)(bian)(bian)比(bi)，而不需(xu)(xu)要更換(huan)(huan)電(dian)(dian)(dian)流互(hu)(hu)(hu)(hu)感(gan)器(qi)(qi)(qi)，給(gei)使用(yong)提(ti)供(gong)了(le)方(fang)便。為便于(yu)二(er)次(ci)(ci)儀表測量需(xu)(xu)要轉換(huan)(huan)為比(bi)較(jiao)統(tong)一(yi)(yi)(yi)的(de)(de)電(dian)(dian)(dian)流電(dian)(dian)(dian)壓，互(hu)(hu)(hu)(hu)感(gan)器(qi)(qi)(qi)油(you)箱加工，使用(yong)互(hu)(hu)(hu)(hu)感(gan)器(qi)(qi)(qi)起到變(bian)(bian)(bian)(bian)流變(bian)(bian)(bian)(bian)壓和(he)電(dian)(dian)(dian)氣(qi)隔(ge)離的(de)(de)作用(yong)。互(hu)(hu)(hu)(hu)感(gan)器(qi)(qi)(qi)還可用(yong)來隔(ge)開高(gao)電(dian)(dian)(dian)壓系統(tong)，互(hu)(hu)(hu)(hu)感(gan)器(qi)(qi)(qi)油(you)箱加工公司，以保證人(ren)身和(he)設(she)備的(de)(de)安全。由于(yu)穿心式電(dian)(dian)(dian)流互(hu)(hu)(hu)(hu)感(gan)器(qi)(qi)(qi)不設(she)一(yi)(yi)(yi)次(ci)(ci)繞組(zu)(zu)，其變(bian)(bian)(bian)(bian)比(bi)根據(ju)一(yi)(yi)(yi)次(ci)(ci)繞組(zu)(zu)穿過互(hu)(hu)(hu)(hu)感(gan)器(qi)(qi)(qi)鐵心中(zhong)的(de)(de)匝(za)數(shu)(shu)確(que)定(ding)，穿心匝(za)數(shu)(shu)越多(duo)，變(bian)(bian)(bian)(bian)比(bi)越小；反之，穿心匝(za)數(shu)(shu)越少(shao)，變(bian)(bian)(bian)(bian)比(bi)越大。

為便于二次儀表測(ce)量(liang)需(xu)要轉換為比較(jiao)統一的(de)電(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)壓，互(hu)感(gan)器油箱(xiang)加工價格，使用(yong)互(hu)感(gan)器起(qi)到變(bian)流(liu)變(bian)壓和電(dian)(dian)(dian)氣隔離的(de)作用(yong)。互(hu)感(gan)器還可(ke)用(yong)來隔開(kai)高電(dian)(dian)(dian)壓系(xi)統，以保證人身和設備的(de)安全。量(liang)很小(xiao)的(de)互(hu)感(gan)器采用(yong)平板式(shi)油箱(xiang)；中(zhong)、小(xiao)型互(hu)感(gan)器為增加散(san)熱表面采用(yong)管式(shi)油箱(xiang)；大容量(liang)互(hu)感(gan)器采用(yong)散(san)熱器式(shi)油箱(xiang)。電(dian)(dian)(dian)流(liu)互(hu)感(gan)器的(de)優(you)點是可(ke)以根據負荷電(dian)(dian)(dian)流(liu)變(bian)比，調換二次接線端子(zi)的(de)接線來改(gai)變(bian)變(bian)比，而不(bu)需(xu)要更換電(dian)(dian)(dian)流(liu)互(hu)感(gan)器，給使用(yong)提供(gong)了方(fang)便。

互感(gan)器(qi)(qi)(qi)又(you)稱(cheng)為儀(yi)用(yong)變(bian)壓器(qi)(qi)(qi)，是電(dian)(dian)流(liu)互感(gan)器(qi)(qi)(qi)和電(dian)(dian)壓互感(gan)器(qi)(qi)(qi)的(de)統(tong)稱(cheng)。能將(jiang)高電(dian)(dian)壓變(bian)成低電(dian)(dian)壓、大(da)電(dian)(dian)流(liu)變(bian)成小電(dian)(dian)流(liu)，用(yong)于量(liang)測或保護(hu)系統(tong)。穿心式(shi)(shi)電(dian)(dian)流(liu)互感(gan)器(qi)(qi)(qi)其本身(shen)結構(gou)不設一次繞組(zu)，載(zai)流(liu)（負(fu)荷電(dian)(dian)流(liu)）導線由L1至(zhi)L2穿過由硅鋼片(pian)搟卷制成的(de)圓形(xing)（或其他(ta)形(xing)狀）鐵(tie)心起一次繞組(zu)作用(yong)。量(liang)很小的(de)互感(gan)器(qi)(qi)(qi)采用(yong)平板式(shi)(shi)油箱；中、小型互感(gan)器(qi)(qi)(qi)為增加散(san)(san)熱表面采用(yong)管式(shi)(shi)油箱；大(da)容量(liang)互感(gan)器(qi)(qi)(qi)采用(yong)散(san)(san)熱器(qi)(qi)(qi)式(shi)(shi)油箱。
