KDHL-200A 回路電阻測試(shi)儀(yi).性能(neng) .特點技術.

KDHL-200智能回路(lu)電(dian)(dian)阻測(ce)試(shi)(shi)儀(yi)采用(yong)大(da)功(gong)率開關(guan)電(dian)(dian)源技術和電(dian)(dian)子線(xian)路(lu)精制(zhi)而成。回路(lu)電(dian)(dian)阻測(ce)試(shi)(shi)儀(yi)是高(gao)、低開關(guan)、電(dian)(dian)纜電(dian)(dian)線(xian)及焊縫接觸電(dian)(dian)阻的(de)專用(yong)測(ce)試(shi)(shi)儀(yi)器。回路(lu)電(dian)(dian)阻測(ce)試(shi)(shi)儀(yi)電(dian)(dian)流采用(yong)國家標(biao)(biao)準(zhun)(zhun)GB736所推薦的(de)標(biao)(biao)準(zhun)(zhun)直流，可(ke)在標(biao)(biao)準(zhun)(zhun)電(dian)(dian)流的(de)情(qing)況下測(ce)得被試(shi)(shi)品的(de)電(dian)(dian)阻值。回路(lu)電(dian)(dian)阻測(ce)試(shi)(shi)儀(yi)具有體(ti)積小、重量輕、抗干擾(rao)能力(li)強、精度高(gao)、操作方便(bian)、保(bao)護功(gong)能完善等特點(dian)。

KDHL-200智能回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)阻(zu)測(ce)試(shi)(shi)儀也稱斷(duan)路(lu)(lu)(lu)器(qi)導電(dian)(dian)(dian)(dian)(dian)回(hui)路(lu)(lu)(lu)。是檢測(ce)導電(dian)(dian)(dian)(dian)(dian)性(xing)能的(de)(de)好(hao)壞(huai)，對(dui)(dui)保障(zhang)開(kai)(kai)關(guan)的(de)(de)安全(quan)運行具有(you)重要作用(yong)。導電(dian)(dian)(dian)(dian)(dian)性(xing)能的(de)(de)優(you)劣(lie)可以(yi)通(tong)過導電(dian)(dian)(dian)(dian)(dian)回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)阻(zu)的(de)(de)大小反映出來。因此IEC標準及(ji)制造廠都(dou)規(gui)(gui)定應測(ce)量回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)阻(zu)，并且對(dui)(dui)各種形(xing)式的(de)(de)開(kai)(kai)關(guan)的(de)(de)回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)阻(zu)有(you)明(ming)確(que)規(gui)(gui)定指標。一般過去使用(yong)雙臂電(dian)(dian)(dian)(dian)(dian)橋(qiao)。由于電(dian)(dian)(dian)(dian)(dian)橋(qiao)的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)，電(dian)(dian)(dian)(dian)(dian)流都(dou)比較小，當開(kai)(kai)關(guan)的(de)(de)動靜(jing)觸頭之間有(you)雜質或表面有(you)氧(yang)化(hua)等，測(ce)試(shi)(shi)的(de)(de)數據分散性(xing)就較大。同時電(dian)(dian)(dian)(dian)(dian)橋(qiao)的(de)(de)抗干擾性(xing)差，因此國家(jia)標準規(gui)(gui)定必須使用(yong)200A以(yi)上(shang)直(zhi)流電(dian)(dian)(dian)(dian)(dian)流進行測(ce)試(shi)(shi)。回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)阻(zu)測(ce)試(shi)(shi)儀是我公司為適(shi)應GB50150-2006和(he)DL/T 845.4-2004規(gui)(gui)程(cheng)要求開(kai)(kai)發的(de)(de)測(ce)試(shi)(shi)儀器(qi)，廣泛適(shi)用(yong)于各種電(dian)(dian)(dian)(dian)(dian)器(qi)開(kai)(kai)關(guan)的(de)(de)接(jie)觸電(dian)(dian)(dian)(dian)(dian)阻(zu)、回(hui)路(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)阻(zu)及(ji)電(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)線(xian)、焊縫接(jie)觸電(dian)(dian)(dian)(dian)(dian)阻(zu)的(de)(de)測(ce)量
