產品別名

電纜識別儀、帶電電纜識(shi)別(bie)儀、電纜故障檢測儀、電纜故障識(shi)別(bie)儀

工作原理：

    為了可靠(kao)準確地識別(bie)電(dian)纜，需要給被(bei)識別(bie)電(dian)纜加一(yi)特(te)(te)殊(shu)的(de)信號，該信號要被(bei)接收機接收，利用這一(yi)特(te)(te)性便能識別(bie)出要找的(de)電(dian)纜。

    發生器將周(zhou)期性的(de)(de)(de)單極性電(dian)(dian)(dian)(dian)(dian)壓脈沖饋入要識別的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)纜(lan)中，該(gai)電(dian)(dian)(dian)(dian)(dian)纜(lan)需要在遠端接地，以(yi)保證有足夠大的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)流(liu)(liu)(liu)過(guo)(guo)電(dian)(dian)(dian)(dian)(dian)纜(lan)。該(gai)系統要設(she)計成返(fan)(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)不要從同一(yi)(yi)(yi)電(dian)(dian)(dian)(dian)(dian)纜(lan) 中返(fan)(fan)回(hui)(hui)，能做(zuo)到這一(yi)(yi)(yi)點，饋入電(dian)(dian)(dian)(dian)(dian)纜(lan)中的(de)(de)(de)脈沖電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)(de)方向可做(zuo)為(wei)一(yi)(yi)(yi)明顯(xian)的(de)(de)(de)識別標準(zhun)，流(liu)(liu)(liu)出(chu)去的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)僅(jin)從這一(yi)(yi)(yi)根電(dian)(dian)(dian)(dian)(dian)纜(lan)通(tong)(tong)過(guo)(guo)，所有其(qi)它鄰近電(dian)(dian)(dian)(dian)(dian)纜(lan)中流(liu)(liu)(liu)過(guo)(guo)的(de)(de)(de)都是返(fan)(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，但 它們(men)的(de)(de)(de)極性相(xiang)反。除了電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)方向這一(yi)(yi)(yi)實際差(cha)異外(wai)，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)幅度也是一(yi)(yi)(yi)識別特(te)征，流(liu)(liu)(liu)出(chu)去的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)僅(jin)通(tong)(tong)過(guo)(guo)一(yi)(yi)(yi)根電(dian)(dian)(dian)(dian)(dian)纜(lan)、而返(fan)(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)可通(tong)(tong)過(guo)(guo)幾(ji)根電(dian)(dian)(dian)(dian)(dian)纜(lan)、這意(yi)味著流(liu)(liu)(liu)出(chu)去的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)比 流(liu)(liu)(liu)過(guo)(guo)其(qi)它電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)返(fan)(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大。

    接(jie)(jie)收(shou)機的(de)(de)(de)任務是(shi)探(tan)測(ce)流(liu)(liu)(liu)(liu)過(guo)電(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)方(fang)(fang)向(xiang)以及它的(de)(de)(de)大小。為達到這一(yi)目的(de)(de)(de)，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)傳(chuan)感(gan)(gan)器被(bei)用作傳(chuan)感(gan)(gan)器，它帶有(you)一(yi)放大器并串聯在電(dian)(dian)(dian)(dian)(dian)路中，傳(chuan)感(gan)(gan)器鉗(qian)住被(bei)測(ce)電(dian)(dian)(dian)(dian)(dian)纜， 電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)流(liu)(liu)(liu)(liu)過(guo)電(dian)(dian)(dian)(dian)(dian)纜產生(sheng)的(de)(de)(de)磁場在傳(chuan)感(gan)(gan)器的(de)(de)(de)線(xian)(xian)圈(quan)中感(gan)(gan)應出電(dian)(dian)(dian)(dian)(dian)壓(ya)，該電(dian)(dian)(dian)(dian)(dian)壓(ya)極(ji)性由(you)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)方(fang)(fang)向(xiang)和(he)傳(chuan)感(gan)(gan)器線(xian)(xian)圈(quan)的(de)(de)(de)方(fang)(fang)向(xiang)決定。為了得(de)到明(ming)顯有(you)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)方(fang)(fang)向(xiang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)極(ji)性，對一(yi)束(shu)電(dian)(dian)(dian)(dian)(dian)纜中所有(you) 電(dian)(dian)(dian)(dian)(dian)纜進行測(ce)試(shi)都采取相(xiang)同(tong)正確(que)的(de)(de)(de)方(fang)(fang)向(xiang)。傳(chuan)感(gan)(gan)器線(xian)(xian)圈(quan)中感(gan)(gan)應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)在表(biao)頭中顯示(shi)出來(lai)，如果傳(chuan)感(gan)(gan)器按(an)上(shang)述方(fang)(fang)式(shi)連接(jie)(jie)，指針擺動方(fang)(fang)向(xiang)可(ke)顯示(shi)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)方(fang)(fang)向(xiang)，即只有(you)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)流(liu)(liu)(liu)(liu)出的(de)(de)(de) 這根電(dian)(dian)(dian)(dian)(dian)纜指針向(xiang)一(yi)邊偏，這根就是(shi)要找(zhao)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)纜。所有(you)其它電(dian)(dian)(dian)(dian)(dian)纜只流(liu)(liu)(liu)(liu)過(guo)返回電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，指針向(xiang)另一(yi)邊偏、或無(wu)脈動電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，指針不偏轉(zhuan)。接(jie)(jie)收(shou)機上(shang)的(de)(de)(de)放大調節器可(ke)調整信(xin)號(hao)強(qiang) 度(du)。
