JYL回路電阻測試儀(200A) 的詳細介紹


JYL回路(lu)電阻測試儀(yi)(200A)


一、概述

斷路器(qi)（以下(xia)簡稱開(kai)(kai)關）導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)回(hui)路的(de)(de)(de)(de)(de)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)(xing)能(neng)(neng)的(de)(de)(de)(de)(de)好壞，對保障開(kai)(kai)關的(de)(de)(de)(de)(de)安(an)全(quan)運行(xing)具有重要作用。導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)(xing)能(neng)(neng)的(de)(de)(de)(de)(de)優劣(lie)可以通過(guo)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)回(hui)路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)的(de)(de)(de)(de)(de)大小反映出來。因此IEC標準及制(zhi)造廠都(dou)規(gui)(gui)定應(ying)測量(liang)回(hui)路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)，并且對各種(zhong)(zhong)形式的(de)(de)(de)(de)(de)開(kai)(kai)關的(de)(de)(de)(de)(de)回(hui)路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)有明確規(gui)(gui)定指標。一般過(guo)去使用雙臂電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)橋(qiao)。由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)橋(qiao)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流都(dou)比(bi)較小，當(dang)開(kai)(kai)關的(de)(de)(de)(de)(de)動(dong)靜(jing)觸頭之間有雜質或表面有氧化等，測試(shi)的(de)(de)(de)(de)(de)數(shu)據分散性(xing)(xing)就較大。同時電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)橋(qiao)的(de)(de)(de)(de)(de)抗干擾性(xing)(xing)差。因此再GB50150-91和(he)DL/T596-1996中都(dou)有規(gui)(gui)定“用直(zhi)流壓(ya)強(qiang)法”， “電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不小于(yu)100安(an)”。JYL回(hui)路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)測試(shi)儀（200A）是我公(gong)司(si)為適應(ying)規(gui)(gui)程要求(qiu)，廣泛適用于(yu)各種(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)開(kai)(kai)關的(de)(de)(de)(de)(de)接觸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)、回(hui)路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線、焊縫接觸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)的(de)(de)(de)(de)(de)測量(liang)。
