ETCR8100B變(bian)壓器鐵芯(xin)接地(di)電流測試(shi)(shi)儀是(shi)專為現場在線(xian)測試(shi)(shi)電力系統中變壓器鐵芯接地電流、漏電流而精心設計制造(zao)的，由(you)主機、電(dian)流鉗、監控軟件、通訊線等組成(cheng)。電(dian)(dian)(dian)(dian)(dian)力變(bian)(bian)壓(ya)器(qi)是電(dian)(dian)(dian)(dian)(dian)力系(xi)統中重(zhong)要(yao)的(de)電(dian)(dian)(dian)(dian)(dian)氣設備(bei)，運行(xing)中一旦出(chu)現(xian)故(gu)障，將會對(dui)電(dian)(dian)(dian)(dian)(dian)力系(xi)統造(zao)成嚴重(zhong)的(de)后果。正(zheng)常運行(xing)的(de)變(bian)(bian)壓(ya)器(qi)鐵(tie)芯(xin)(xin)是單點(dian)(dian)接地(di)的(de)，如有兩(liang)(liang)點(dian)(dian)或兩(liang)(liang)點(dian)(dian)以上(shang)同時接地(di)，則(ze)鐵(tie)芯(xin)(xin)與大地(di)之間將形成電(dian)(dian)(dian)(dian)(dian)流回路，電(dian)(dian)(dian)(dian)(dian)流可(ke)達幾(ji)十安(an)培(pei)，將會造(zao)成鐵(tie)芯(xin)(xin)局部(bu)過熱甚至(zhi)燒毀。本儀表能(neng)盡快發(fa)現(xian)變(bian)(bian)壓(ya)器(qi)潛伏性的(de)故(gu)障，是保證變(bian)(bian)壓(ya)器(qi)安(an)全運行(xing)和正(zheng)常維護的(de)主要(yao)工具。主要(yao)適用于(yu)(yu)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)、發(fa)電(dian)(dian)(dian)(dian)(dian)廠(chang)作為變(bian)(bian)壓(ya)器(qi)、電(dian)(dian)(dian)(dian)(dian)抗器(qi)等電(dian)(dian)(dian)(dian)(dian)氣設備(bei)的(de)鐵(tie)芯(xin)(xin)與夾件(jian)的(de)泄(xie)漏電(dian)(dian)(dian)(dian)(dian)流測試。也(ye)可(ke)用于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)力、通信、氣象、鐵(tie)路、油田、建(jian)筑、計量、科研教(jiao)學(xue)單位、工礦企業等領域線路或設備(bei)的(de)電(dian)(dian)(dian)(dian)(dian)流、漏電(dian)(dian)(dian)(dian)(dian)流測試。

變壓器鐵芯接(jie)地電流測(ce)試儀主機(ji)采用(yong)高速微處理(li)器，3.5寸(cun)彩色觸摸(mo)液晶屏，智能觸摸(mo)操作，方便(bian)快捷。能實時顯示被(bei)測(ce)電(dian)流的大小(xiao)及波形；運(yun)用FFT變換、數(shu)(shu)字濾波等技術，使測試數(shu)(shu)據(ju)更準(zhun)確；具(ju)有報警臨界值設(she)定及報警指示功能(neng)；具(ju)有日期(qi)時(shi)(shi)鐘(zhong)及設(she)置功能(neng)；具(ju)有自(zi)動關(guan)機時(shi)(shi)間功能(neng)；具(ju)有設(she)定試品編號功能(neng)；具(ju)有USB接口(kou)，可將存儲數據導入電(dian)腦，儀表可以存儲數據及波形200組(zu)。

電(dian)流鉗(qian)(qian)選用特殊合金，采用磁(ci)性(xing)屏(ping)蔽(bi)技(ji)術(shu)，外界磁(ci)場影響小，抗干(gan)擾能力強，確保(bao)了常年無間斷測(ce)量的(de)高精度、高穩定性(xing)、高可(ke)靠性(xing)。其鉗(qian)(qian)口(kou)內徑為80mm×80mm，可(ke)鉗(qian)(qian)φ80mm以下的(de)電(dian)纜(lan)或接地(di)線，或鉗(qian)(qian)96mm×;4mm扁鋼地(di)線，便攜(xie)式鉗形設計，不必斷開被測線路，非接觸(chu)測量(liang)，安全快速(su)。

監(jian)控軟件具有在線實時監(jian)控與歷史查詢功能，動態(tai)顯示，波形指示；具有報(bao)警值設置(zhi)及報(bao)警指示；具有歷史數據讀取、查閱、保存(cun)、打印等功能。
