簡要介紹(shao)

■ TH5703型接(jie)地電(dian)(dian)(dian)(dian)阻(zu)測(ce)(ce)(ce)試(shi)儀是用來(lai)測(ce)(ce)(ce)量(liang)電(dian)(dian)(dian)(dian)氣設備內部的(de)接(jie)地電(dian)(dian)(dian)(dian)阻(zu)，它(ta)所(suo)反映的(de)是電(dian)(dian)(dian)(dian)氣設備的(de)各處外(wai)露(lu)可導(dao)部分與(yu)電(dian)(dian)(dian)(dian)氣設備的(de)總(zong)接(jie)地端子(zi)之(zhi)間(jian)的(de)（接(jie)觸）電(dian)(dian)(dian)(dian)阻(zu)。接(jie)地電(dian)(dian)(dian)(dian)阻(zu)測(ce)(ce)(ce)試(shi)儀為了消除接(jie)觸電(dian)(dian)(dian)(dian)阻(zu)對(dui)測(ce)(ce)(ce)試(shi)的(de)影響(xiang)，采用四段測(ce)(ce)(ce)量(liang)法，即在被測(ce)(ce)(ce)電(dian)(dian)(dian)(dian)氣的(de)外(wai)露(lu)可導(dao)部分和總(zong)接(jie)地端子(zi)之(zhi)間(jian)加上電(dian)(dian)(dian)(dian)流(liu)，然后再測(ce)(ce)(ce)量(liang)這兩端的(de)電(dian)(dian)(dian)(dian)壓，算出(chu)其(qi)電(dian)(dian)(dian)(dian)阻(zu)值。本產品(pin)滿(man)足GB4706.1-2005，GB9706.1-2007等國內外(wai)安規(gui)標準測(ce)(ce)(ce)試(shi)，符合JJG984-2004安規(gui)計量(liang)檢定規(gui)程要求。
