根據電(dian)(dian)流(liu)(liu)互(hu)感(gan)(gan)器(qi)(qi)的(de)(de)等值電(dian)(dian)路圖，討論了2種電(dian)(dian)流(liu)(liu)互(hu)感(gan)(gan)器(qi)(qi)變(bian)比(bi)檢查試(shi)驗方(fang)法(fa)（電(dian)(dian)流(liu)(liu)法(fa)和電(dian)(dian)壓法(fa)）的(de)(de)原(yuan)理和特點，推(tui)薦(jian)一(yi)種簡便可靠的(de)(de)電(dian)(dian)流(liu)(liu)互(hu)感(gan)(gan)器(qi)(qi)變(bian)比(bi)檢查現場試(shi)驗方(fang)法(fa)、電(dian)(dian)壓法(fa)。本文從應用(yong)的(de)(de)角度，在分析接(jie)線(xian)原(yuan)理的(de)(de)基礎上對雙線(xian)圈變(bian)壓器(qi)(qi)差動保(bao)(bao)護(hu)中電(dian)(dian)流(liu)(liu)互(hu)感(gan)(gan)器(qi)(qi)的(de)(de)幾種接(jie)線(xian)方(fang)法(fa)進行(xing)了概括總結；同時介紹(shao)在電(dian)(dian)流(liu)(liu)互(hu)感(gan)(gan)器(qi)(qi)性(xing)不明(ming)的(de)(de)情況下，雙線(xian)圈變(bian)壓器(qi)(qi)差動保(bao)(bao)護(hu)中電(dian)(dian)流(liu)(liu)互(hu)感(gan)(gan)器(qi)(qi)的(de)(de)接(jie)線(xian)方(fang)法(fa)。電(dian)(dian)流(liu)(liu)互(hu)感(gan)(gan)器(qi)(qi)在電(dian)(dian)氣中有著重要(yao)的(de)(de)作用(yong)，因此對電(dian)(dian)流(liu)(liu)互(hu)感(gan)(gan)器(qi)(qi)的(de)(de)一(yi)些(xie)特性(xing)要(yao)求也比(bi)較(jiao)高，以適(shi)應電(dian)(dian)氣上的(de)(de)動作靈敏性(xing)、快(kuai)速(su)性(xing)。斷路器(qi)(qi)分析儀,大電(dian)(dian)流(liu)(liu)測試(shi)儀是專業的(de)(de)...
