產品介(jie)紹(shao)：
接地(di)電(dian)(dian)阻(zu)(zu)(zu)測(ce)試儀是摒棄(qi)了傳統的(de)(de)人工(gong)手搖(yao)發電(dian)(dian)工(gong)作(zuo)方(fang)式，采(cai)用大規(gui)模集成電(dian)(dian)路(lu)，應用DC/AC變換技術將(jiang)三端鈕(niu)、四(si)端鈕(niu)測(ce)量方(fang)式合并(bing)為(wei)一種機型的(de)(de)新型數字接地(di)電(dian)(dian)阻(zu)(zu)(zu)測(ce)試儀。適用于電(dian)(dian)力、郵電(dian)(dian)、鐵路(lu)、通(tong)信、礦(kuang)山(shan)等部門測(ce)量各種裝置的(de)(de)接地(di)電(dian)(dian)阻(zu)(zu)(zu)以及(ji)測(ce)量低電(dian)(dian)阻(zu)(zu)(zu)的(de)(de)導(dao)體電(dian)(dian)阻(zu)(zu)(zu)值；本(ben)表還(huan)可測(ce)量土壤電(dian)(dian)阻(zu)(zu)(zu)率及(ji)地(di)電(dian)(dian)壓。
接地(di)電阻(zu)測試儀是檢驗測量接地電阻的常(chang)用儀表，也是電氣safe檢查(cha)與接地工程竣工驗收不(bu)可(ke)缺少的(de)工具，進年(nian)來由(you)于計算機技(ji)術的(de)飛速(su)發展(zhan)，因此接(jie)地(di)(di)電(dian)阻測(ce)(ce)(ce)試(shi)儀(yi)(yi)也滲透了大量(liang)的(de)接(jie)地(di)(di)電(dian)阻測(ce)(ce)(ce)試(shi)儀(yi)(yi)微(wei)處(chu)理機技(ji)術，其測(ce)(ce)(ce)量(liang)功能(neng)，內容與精度是一般(ban)儀(yi)(yi)器(qi)(qi)所不(bu)能(neng)相(xiang)比的(de)。目前邦信電(dian)阻測(ce)(ce)(ce)試(shi)儀(yi)(yi)能(neng)滿足(zu)所有接(jie)地(di)(di)測(ce)(ce)(ce)量(liang)要求。運(yun)用新式鉗(qian)口法，無需(xu)打(da)裝樁放線(xian)進行在線(xian)直接(jie)測(ce)(ce)(ce)量(liang)。一臺功能(neng)強(qiang)大的(de)地(di)(di)阻測(ce)(ce)(ce)試(shi)儀(yi)(yi)均由(you)微(wei)處(chu)理器(qi)(qi)控制，可(ke)自(zi)動(dong)檢測(ce)(ce)(ce)各接(jie)口連(lian)接(jie)狀(zhuang)況及地網的干擾電壓、干擾頻率，并具有數值保(bao)持及智能提示等功能。
鉗形(xing)(xing)接(jie)(jie)地(di)(di)(di)(di)電(dian)(dian)(dian)阻(zu)儀(yi)是傳(chuan)(chuan)統接(jie)(jie)地(di)(di)(di)(di)電(dian)(dian)(dian)阻(zu)測(ce)(ce)量技術的(de)重大突(tu)破，廣泛應用于(yu)電(dian)(dian)(dian)力、電(dian)(dian)(dian)信(xin)、氣象(xiang)、油田、建筑及工業(ye)電(dian)(dian)(dian)氣設備的(de)接(jie)(jie)地(di)(di)(di)(di)電(dian)(dian)(dian)阻(zu)測(ce)(ce)量。鉗形(xing)(xing)接(jie)(jie)地(di)(di)(di)(di)電(dian)(dian)(dian)阻(zu)儀(yi)在測(ce)(ce)量有回路的(de)接(jie)(jie)地(di)(di)(di)(di)系統時，不需斷開接(jie)(jie)地(di)(di)(di)(di)引(yin)(yin)下線，不需輔助電(dian)(dian)(dian)極，safe快速、使(shi)用簡(jian)便。邦信(xin)鉗形(xing)(xing)接(jie)(jie)地(di)(di)(di)(di)電(dian)(dian)(dian)阻(zu)儀(yi)能測(ce)(ce)量出用傳(chuan)(chuan)統方法(fa)(fa)無(wu)法(fa)(fa)測(ce)(ce)量的(de)接(jie)(jie)地(di)(di)(di)(di)故(gu)障，能應用于(yu)傳(chuan)(chuan)統方法(fa)(fa)無(wu)法(fa)(fa)測(ce)(ce)量的(de)場合(he)(he)，因為鉗形(xing)(xing)接(jie)(jie)地(di)(di)(di)(di)電(dian)(dian)(dian)阻(zu)儀(yi)測(ce)(ce)量的(de)是接(jie)(jie)地(di)(di)(di)(di)體電(dian)(dian)(dian)阻(zu)和接(jie)(jie)地(di)(di)(di)(di)引(yin)(yin)線電(dian)(dian)(dian)阻(zu)的(de)綜合(he)(he)值。鉗形(xing)(xing)接(jie)(jie)地(di)(di)(di)(di)電(dian)(dian)(dian)阻(zu)儀(yi)有長(chang)鉗口(kou)及圓鉗口(kou)之(zhi)分。長(chang)鉗口(kou)適宜于(yu)扁鋼接(jie)(jie)地(di)(di)(di)(di)的(de)場合(he)(he)。
