一、產品介紹(shao)

    CHD1000鉗型接(jie)(jie)地(di)(di)(di)(di)電(dian)阻(zu)(zu)測(ce)試儀是(shi)傳統(tong)接(jie)(jie)地(di)(di)(di)(di)電(dian)阻(zu)(zu)測(ce)量(liang)(liang)技術的(de)(de)重大突破(po)。經過防爆技術的(de)(de)設計,鉗型接(jie)(jie)地(di)(di)(di)(di)電(dian)阻(zu)(zu)測(ce)試儀可以在煤礦井下對電(dian)氣設備的(de)(de)接(jie)(jie)地(di)(di)(di)(di)電(dian)阻(zu)(zu)進行(xing)測(ce)量(liang)(liang)。在測(ce)量(liang)(liang)有(you)回(hui)路的(de)(de)接(jie)(jie)地(di)(di)(di)(di)系統(tong)時,不需(xu)斷開接(jie)(jie)地(di)(di)(di)(di)引(yin)(yin)下線(xian),不需(xu)輔助電(dian)極,安(an)全快速,使用(yong)簡便。本產(chan)品(pin)能測(ce)量(liang)(liang)出(chu)用(yong)傳統(tong)方法(fa)無(wu)法(fa)測(ce)量(liang)(liang)的(de)(de)接(jie)(jie)地(di)(di)(di)(di)故(gu)障,能應用(yong)于傳統(tong)方法(fa)無(wu)法(fa)測(ce)量(liang)(liang)的(de)(de)場合(he),本產(chan)品(pin)的(de)(de)接(jie)(jie)地(di)(di)(di)(di)體(ti)電(dian)阻(zu)(zu)和接(jie)(jie)地(di)(di)(di)(di)引(yin)(yin)線(xian)電(dian)阻(zu)(zu)的(de)(de)綜合(he)值。

二、工作原理

鉗(qian)(qian)形接地電(dian)(dian)(dian)(dian)阻測試儀測量(liang)接地電(dian)(dian)(dian)(dian)阻的基本原理是測量(liang)回路電(dian)(dian)(dian)(dian)阻。鉗(qian)(qian)表(biao)的鉗(qian)(qian)口(kou)部分由電(dian)(dian)(dian)(dian)壓線(xian)(xian)圈及電(dian)(dian)(dian)(dian)流(liu)線(xian)(xian)圈組成。電(dian)(dian)(dian)(dian)壓線(xian)(xian)圈提供激勵信號,并(bing)在被測回路上感應一個電(dian)(dian)(dian)(dian)勢E。在電(dian)(dian)(dian)(dian)勢E的作用下將(jiang)在被測回路產(chan)生電(dian)(dian)(dian)(dian)流(liu)I。鉗(qian)(qian)表(biao)對E及I進(jin)行測量(liang),并(bing)通過(guo)下面(mian)的公(gong)式即可得到被測電(dian)(dian)(dian)(dian)阻R。
