近些年來，國內多處變電站因雷擊形成擴大事故，多數是與地網接地電阻出現了問題。而對于一個工廠來說，一旦設備的電阻電壓出現問題，就會直接影響到它的使用，因此每隔一段時間，我們就要對設備的電阻進行檢測。
首先用萬用表檢查(cha)用于試驗的(de)電流線、電壓(ya)線和地網(wang)線是否有斷路(lu)現象，將地樁(zhuang)上的(de)鐵銹清除干凈，確保埋進深度大于0.5米，同時檢查(cha)測試線與地樁(zhuang)的(de)連(lian)接(jie)是否導(dao)通(tong)，如未導(dao)通(tong)則(ze)需要重新(xin)連(lian)接(jie)。
電(dian)(dian)(dian)(dian)流(liu)測(ce)試(shi)(shi)線(xian)(xian)(xian)(xian)和電(dian)(dian)(dian)(dian)壓測(ce)試(shi)(shi)線(xian)(xian)(xian)(xian)按規定的長度(du)（電(dian)(dian)(dian)(dian)流(liu)測(ce)試(shi)(shi)線(xian)(xian)(xian)(xian)與(yu)電(dian)(dian)(dian)(dian)壓測(ce)試(shi)(shi)線(xian)(xian)(xian)(xian)的長度(du)比為1：0.618，電(dian)(dian)(dian)(dian)流(liu)測(ce)試(shi)(shi)線(xian)(xian)(xian)(xian)的長度(du)應(ying)是地(di)網對角線(xian)(xian)(xian)(xian)的3～5倍），將(jiang)一(yi)端與(yu)儀器相(xiang)接(jie)后平行(xing)放出，另(ling)一(yi)端分(fen)別接(jie)在兩個地(di)樁上(shang)。然后將(jiang)萬(wan)用表(biao)一(yi)端接(jie)電(dian)(dian)(dian)(dian)流(liu)線(xian)(xian)(xian)(xian)或電(dian)(dian)(dian)(dian)壓線(xian)(xian)(xian)(xian)，另(ling)一(yi)端接(jie)地(di)網線(xian)(xian)(xian)(xian)，檢查無(wu)誤后，給儀器接(jie)上(shang)AC 220V/50Hz電(dian)(dian)(dian)(dian)源，通電(dian)(dian)(dian)(dian)開始測(ce)量，記錄測(ce)試(shi)(shi)數據，關掉(diao)電(dian)(dian)(dian)(dian)源，拆除連線(xian)(xian)(xian)(xian)后，測(ce)試(shi)(shi)就(jiu)結(jie)束了。
做(zuo)企(qi)業(ye)(ye)(ye)最怕產(chan)品(pin)賣不出(chu)去(qu)，企(qi)業(ye)(ye)(ye)沒有度。現在是互聯網(wang)時(shi)代，酒香(xiang)不怕巷子深的時(shi)代已經過去(qu)了(le)。想做(zuo)好(hao)銷(xiao)售(shou)，請免(mian)費(fei)注(zhu)冊(ce)愛客商(shang)(shang)務(wu)網(wang)會員，可(ke)以免(mian)費(fei)發布產(chan)品(pin)銷(xiao)售(shou)信(xin)息、行業(ye)(ye)(ye)展會信(xin)息、招商(shang)(shang)加盟信(xin)息，還(huan)能發布企(qi)業(ye)(ye)(ye)新(xin)聞、新(xin)品(pin)速遞(di)等(deng)廣(guang)告文(wen)章(zhang)。愛客商(shang)(shang)務(wu)網(wang)旗(qi)下還(huan)有十幾家垂直(zhi)商(shang)(shang)業(ye)(ye)(ye)網(wang)站，如塑(su)料(liao)商(shang)(shang)務(wu)網(wang)，化工商(shang)(shang)務(wu)網(wang)，儀器商(shang)(shang)務(wu)網(wang)等(deng)。注(zhu)冊(ce)一(yi)個賬號就可(ke)以在十多(duo)個平(ping)臺(tai)發布商(shang)(shang)業(ye)(ye)(ye)信(xin)息，展示。同行都在行動，您可(ke)千萬別忘了(le)哦。
大型地網接地電阻測試儀的測試過程方便快捷，功能強大，目前在國內處于水平，其良好的功能特性越來越受用戶的喜愛，越來越成為工廠測試電阻的選擇。本(ben)期就為大(da)家分享(xiang)到這里了，持續(xu)關(guan)(guan)注本(ben)公(gong)司，可以了解(jie)更多(duo)相關(guan)(guan)內(nei)容哦。
