一、 概述
KQ-ER03雙(shuang)鉗口接地電(dian)(dian)(dian)(dian)(dian)阻測試儀適用于(yu)各種設備(bei)及(ji)建筑物接地電(dian)(dian)(dian)(dian)(dian)阻測試。如通信設備(bei)、電(dian)(dian)(dian)(dian)(dian)信電(dian)(dian)(dian)(dian)(dian)纜、機房、電(dian)(dian)(dian)(dian)(dian)力配電(dian)(dian)(dian)(dian)(dian)線(xian)路、電(dian)(dian)(dian)(dian)(dian)塔輸(shu)電(dian)(dian)(dian)(dian)(dian)線(xian)路、加油站(zhan)、工廠接地網、避(bi)雷針等,還可測量各種條件下的土壤電(dian)(dian)(dian)(dian)(dian)阻率及(ji)接地系統泄漏電(dian)(dian)(dian)(dian)(dian)流。
該儀表(biao)除了(le)具(ju)有傳(chuan)統(tong)打(da)輔助地級測(ce)(ce)接地電阻(zu)的功能外,還具(ju)備了(le)無輔助地極(ji)測(ce)(ce)量的獨(du)特功能,改變(bian)了(le)測(ce)(ce)試接地電阻(zu)傳(chuan)統(tong)的測(ce)(ce)量原理和手段(duan)。采用(yong)二點極(ji)測(ce)(ce)量原理和利用(yong)雙鉗口測(ce)(ce)量技術,無需打(da)輔助地極(ji)、無需將接地體與設(she)備隔離(li),實現(xian)了(le)在線測(ce)(ce)量。
本機具有智能化測量功能,不僅能自(zi)動(dong)校準(zhun),而且還能儲(chu)存和瀏(liu)覽結果,并肩有數據(ju)上傳功能,可在PC機上進行(xing)數據(ju)分析(xi)。
二、功能特點
