絕緣電阻測試儀的介紹：

     我們測定(ding)產(chan)(chan)業(ye)(ye)的(de)(de)(de)(de)絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)阻，是指(zhi)帶(dai)電(dian)(dian)(dian)(dian)部(bu)(bu)分(fen)與(yu)外(wai)露非帶(dai)電(dian)(dian)(dian)(dian)金 屬部(bu)(bu)分(fen)（外(wai)殼）之間的(de)(de)(de)(de)絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)阻，按不(bu)同的(de)(de)(de)(de)產(chan)(chan)業(ye)(ye)，施加一直(zhi)流高壓(ya)(ya)，如100V、250V、500V、1000V等(deng)，標(biao)(biao)準(zhun)一個*低的(de)(de)(de)(de)絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)阻值(zhi)。有的(de)(de)(de)(de)指(zhi)標(biao)(biao)標(biao)(biao)準(zhun) 每kV電(dian)(dian)(dian)(dian)壓(ya)(ya)，絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)阻不(bu)小于1MΩ等(deng)。目前在家(jia)用電(dian)(dian)(dian)(dian)器產(chan)(chan)業(ye)(ye)指(zhi)標(biao)(biao)中(zhong)，通常只標(biao)(biao)準(zhun)熱態(tai)絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)阻，而不(bu)標(biao)(biao)準(zhun)常態(tai)條件(jian)下(xia)的(de)(de)(de)(de)絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)阻值(zhi)，常態(tai)條件(jian)下(xia)的(de)(de)(de)(de)絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)阻值(zhi)由(you)企(qi) 業(ye)(ye)指(zhi)標(biao)(biao)中(zhong)自行制定(ding)。如果常態(tai)絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)阻值(zhi)低，說(shuo)明絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)結構中(zhong)可能存在某種隱患或(huo)(huo)受損。如電(dian)(dian)(dian)(dian)機繞(rao)組對(dui)外(wai)殼的(de)(de)(de)(de)絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)阻低，可能是在嵌(qian)線時繞(rao)組的(de)(de)(de)(de)均線槽絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)受到損 傷所致。在使用電(dian)(dian)(dian)(dian)器時，由(you)于突然上電(dian)(dian)(dian)(dian)或(huo)(huo)切(qie)斷電(dian)(dian)(dian)(dian)源或(huo)(huo)其(qi)它緣(yuan)(yuan)(yuan)(yuan)(yuan)故(gu)，電(dian)(dian)(dian)(dian)路(lu)產(chan)(chan)生過電(dian)(dian)(dian)(dian)壓(ya)(ya)，在絕(jue)(jue)(jue)(jue)(jue)緣(yuan)(yuan)(yuan)(yuan)(yuan)受損處產(chan)(chan)生擊(ji)穿，造成對(dui)人身的(de)(de)(de)(de)**或(huo)(huo)威(wei)脅。
