KDHL-200智(zhi)能回路(lu)(lu)電(dian)(dian)(dian)(dian)阻(zu)測(ce)(ce)(ce)(ce)試(shi)(shi)(shi)儀(yi)采用(yong)大功(gong)率開(kai)關電(dian)(dian)(dian)(dian)源技術和電(dian)(dian)(dian)(dian)子線(xian)路(lu)(lu)精制而成。回路(lu)(lu)電(dian)(dian)(dian)(dian)阻(zu)測(ce)(ce)(ce)(ce)試(shi)(shi)(shi)儀(yi)是高、低開(kai)關、電(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)線(xian)及焊縫接觸電(dian)(dian)(dian)(dian)阻(zu)的專用(yong)測(ce)(ce)(ce)(ce)試(shi)(shi)(shi)儀(yi)器。回路(lu)(lu)電(dian)(dian)(dian)(dian)阻(zu)測(ce)(ce)(ce)(ce)試(shi)(shi)(shi)儀(yi)電(dian)(dian)(dian)(dian)流采用(yong)國家標(biao)準(zhun)GB736所推薦的標(biao)準(zhun)直流，可在標(biao)準(zhun)電(dian)(dian)(dian)(dian)流的情況下測(ce)(ce)(ce)(ce)得被試(shi)(shi)(shi)品的電(dian)(dian)(dian)(dian)阻(zu)值。回路(lu)(lu)電(dian)(dian)(dian)(dian)阻(zu)測(ce)(ce)(ce)(ce)試(shi)(shi)(shi)儀(yi)具有體積(ji)小、重量(liang)輕、抗干擾能力(li)強(qiang)、精度高、操作(zuo)方便(bian)、保護(hu)功(gong)能完(wan)善等(deng)特點(dian)。

KDHL-200智(zhi)能(neng)(neng)回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)阻(zu)(zu)測(ce)(ce)試(shi)(shi)(shi)儀(yi)也稱(cheng)斷路(lu)(lu)(lu)器(qi)(qi)導電(dian)(dian)(dian)回(hui)路(lu)(lu)(lu)。是檢測(ce)(ce)導電(dian)(dian)(dian)性(xing)能(neng)(neng)的(de)(de)(de)好(hao)壞，對保障開(kai)關的(de)(de)(de)安全運行具有(you)重要作用(yong)。導電(dian)(dian)(dian)性(xing)能(neng)(neng)的(de)(de)(de)優劣(lie)可(ke)以通過導電(dian)(dian)(dian)回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)阻(zu)(zu)的(de)(de)(de)大(da)小反(fan)映出(chu)來。因(yin)此IEC標(biao)準及(ji)制造廠都規定應測(ce)(ce)量回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)阻(zu)(zu)，并且對各種(zhong)形式的(de)(de)(de)開(kai)關的(de)(de)(de)回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)阻(zu)(zu)有(you)明確(que)規定指標(biao)。一般過去(qu)使用(yong)雙臂電(dian)(dian)(dian)橋。由于電(dian)(dian)(dian)橋的(de)(de)(de)電(dian)(dian)(dian)壓，電(dian)(dian)(dian)流都比較(jiao)小，當開(kai)關的(de)(de)(de)動靜(jing)觸頭之間有(you)雜質或表面有(you)氧化等(deng)，測(ce)(ce)試(shi)(shi)(shi)的(de)(de)(de)數據分散性(xing)就較(jiao)大(da)。同時電(dian)(dian)(dian)橋的(de)(de)(de)抗干(gan)擾性(xing)差，因(yin)此國家標(biao)準規定必須使用(yong)200A以上直流電(dian)(dian)(dian)流進行測(ce)(ce)試(shi)(shi)(shi)。回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)阻(zu)(zu)測(ce)(ce)試(shi)(shi)(shi)儀(yi)是我公司(si)為適應GB50150-2006和DL/T 845.4-2004規程要求開(kai)發的(de)(de)(de)測(ce)(ce)試(shi)(shi)(shi)儀(yi)器(qi)(qi)，廣泛適用(yong)于各種(zhong)電(dian)(dian)(dian)器(qi)(qi)開(kai)關的(de)(de)(de)接觸電(dian)(dian)(dian)阻(zu)(zu)、回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)阻(zu)(zu)及(ji)電(dian)(dian)(dian)纜電(dian)(dian)(dian)線(xian)、焊縫接觸電(dian)(dian)(dian)阻(zu)(zu)的(de)(de)(de)測(ce)(ce)量
