ETCR9100-高低壓鉗形電流表

一．簡介

    ETCR9100高(gao)(gao)壓(ya)鉗形漏電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)突破傳統結(jie)構，專為在線(xian)測(ce)量(liang)高(gao)(gao)壓(ya)線(xian)路的(de)(de)漏電(dian)(dian)(dian)(dian)情(qing)(qing) 況、判斷氧化鋅避雷(lei)器的(de)(de)運行情(qing)(qing)況。采用CT及屏蔽技術，由高(gao)(gao)壓(ya)檢測(ce)儀配(pei)高(gao)(gao)壓(ya)絕(jue)緣桿組成，若不(bu)使用絕(jue)緣桿，還可以(yi)當作高(gao)(gao)精度(du)低壓(ya)鉗形漏電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)、電(dian)(dian)(dian)(dian)流(liu)(liu) 表(biao)使用，能準(zhun)確測(ce)出0.01mA的(de)(de)漏電(dian)(dian)(dian)(dian)流(liu)(liu)或電(dian)(dian)(dian)(dian)流(liu)(liu)。

    ETCR9100高(gao)壓鉗形漏電流(liu)表鉗頭與(yu)引導區創新(xin)的(de)一體化設計，確保了常年(nian)無間斷測試的(de)高(gao)精度、高(gao)可靠性、高(gao)穩定性。絕(jue)緣(yuan)桿輕便，具有防潮﹑耐高(gao)溫﹑抗沖擊(ji)﹑抗彎﹑高(gao)絕(jue)緣(yuan)、可伸縮等特點(dian)。

    ETCR9100高壓(ya)鉗(qian)形漏(lou)電(dian)流(liu)(liu)表連接絕(jue)緣(yuan)桿，可(ke)用于60KV（裸線(xian)35KV） 以下的高壓(ya)線(xian)路漏(lou)電(dian)流(liu)(liu)測(ce)量，在線(xian)電(dian)流(liu)(liu)測(ce)量，判斷(duan)氧化鋅避雷(lei)器是否受潮或(huo)運行(xing)不良，儀表還具有(you)峰值(zhi)保(bao)持(chi)、數據保(bao)持(chi)、數據存儲、無線(xian)傳輸等功(gong)能，其高壓(ya)鉗(qian) 通過按壓(ya)或(huo)退拔絕(jue)緣(yuan)桿能方(fang)便(bian)鉗(qian)夾或(huo)撤離被測(ce)導線(xian)，省時快捷(jie)，廣泛(fan)應用于變(bian)電(dian)站(zhan)﹑發(fa)電(dian)廠﹑工(gong)(gong)礦企業(ye)以及(ji)檢測(ce)站(zhan)﹑電(dian)工(gong)(gong)維修(xiu)部門進行(xing)漏(lou)電(dian)檢測(ce)和野外電(dian)工(gong)(gong)作業(ye)等。

   ETCR9100高(gao)壓鉗形漏電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)表(biao)可作為(wei)高(gao)低壓電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)互(hu)感(gan)器(qi)變比測試(shi)儀(yi)、氧(yang)化(hua)(hua)鋅避(bi)雷(lei) 器(qi)測試(shi)儀(yi)使用。即分別測出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)互(hu)感(gan)器(qi)一二次(ci)回(hui)路的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，再計算得出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)互(hu)感(gan)器(qi)的(de)(de)變比或(huo)折算變比。注意：由(you)于投入(ru)運行(xing)后的(de)(de)避(bi)雷(lei)器(qi)泄漏電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)應(ying)小(xiao)于500uA， 所以可以根據測試(shi)避(bi)雷(lei)器(qi)的(de)(de)漏電(dian)(dian)(dian)(dian)(dian)(dian)情(qing)(qing)況(kuang)(kuang)來判斷避(bi)雷(lei)器(qi)的(de)(de)運行(xing)情(qing)(qing)況(kuang)(kuang)，若(ruo)實測避(bi)雷(lei)器(qi)泄漏電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)過(guo)大，超(chao)過(guo)500uA，若(ruo)排除系統電(dian)(dian)(dian)(dian)(dian)(dian)壓過(guo)高(gao)，則避(bi)雷(lei)器(qi)可能有污漬或(huo)受(shou)潮或(huo) 老化(hua)(hua)，漏電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)越(yue)大，有污漬或(huo)受(shou)潮或(huo)老化(hua)(hua)就越(yue)嚴重。
