TL5703接地電阻測(ce)試儀
簡要介(jie)紹
■ TH5703型接(jie)地(di)(di)電(dian)(dian)阻測(ce)(ce)試儀(yi)是(shi)用來測(ce)(ce)量(liang)電(dian)(dian)氣(qi)設備內部(bu)的(de)接(jie)地(di)(di)電(dian)(dian)阻，它所反映的(de)是(shi)電(dian)(dian)氣(qi)設備的(de)各處外(wai)(wai)露可(ke)導(dao)部(bu)分(fen)(fen)與電(dian)(dian)氣(qi)設備的(de)總接(jie)地(di)(di)端(duan)子(zi)之(zhi)間的(de)（接(jie)觸(chu)）電(dian)(dian)阻。接(jie)地(di)(di)電(dian)(dian)阻測(ce)(ce)試儀(yi)為了(le)消除接(jie)觸(chu)電(dian)(dian)阻對(dui)測(ce)(ce)試的(de)影(ying)響，采用四段測(ce)(ce)量(liang)法，即(ji)在被測(ce)(ce)電(dian)(dian)氣(qi)的(de)外(wai)(wai)露可(ke)導(dao)部(bu)分(fen)(fen)和總接(jie)地(di)(di)端(duan)子(zi)之(zhi)間加上電(dian)(dian)流，然(ran)后再測(ce)(ce)量(liang)這兩端(duan)的(de)電(dian)(dian)壓，算出其(qi)電(dian)(dian)阻值(zhi)。本產(chan)品滿(man)足GB4706.1-2005，GB9706.1-2007等國(guo)內外(wai)(wai)安規(gui)標準測(ce)(ce)試，符合(he)JJG984-2004安規(gui)計(ji)量(liang)檢定規(gui)程要求。
