電纜識別儀報價是(shi)用于將某一(yi)特定電纜(lan)從一(yi)束電纜(lan)中識別出來(lai)的儀器(qi)(qi)。它是(shi)一(yi)小型(xing)化(hua)手提式，緊湊型(xing)儀器(qi)(qi)，裝在(zai)鋁(lv)合金箱(xiang)內(nei)，由一(yi)個信號發生器(qi)(qi)，一(yi)個帶傳感器(qi)(qi)的接收機及連線(xian)構成。

電纜識別儀報價簡介：為了可靠準確地識別(bie)(bie)電(dian)纜(lan)，需要(yao)給被(bei)識別(bie)(bie)電(dian)纜(lan)加一特殊的信號(hao)，該信號(hao)要(yao)被(bei)接(jie)收機(ji)接(jie)收，利用這一特性(xing)便能識別(bie)(bie)出要(yao)找的電(dian)纜(lan)。

工作原理：

發生器將(jiang)周期性的(de)(de)單極(ji)性電(dian)(dian)(dian)壓脈(mo)沖饋(kui)入(ru)要識別的(de)(de)電(dian)(dian)(dian)纜(lan)中(zhong)，該電(dian)(dian)(dian)纜(lan)需要在遠端接(jie)地，以保(bao)證有足夠大(da)的(de)(de)電(dian)(dian)(dian)流(liu)流(liu)過電(dian)(dian)(dian)纜(lan)。該系(xi)統要設計成返(fan)回電(dian)(dian)(dian)流(liu)不要從同一(yi)電(dian)(dian)(dian)纜(lan)中(zhong)返(fan)回，能做到這(zhe)一(yi)點，饋(kui)入(ru)電(dian)(dian)(dian)纜(lan)中(zhong)的(de)(de)脈(mo)沖電(dian)(dian)(dian)流(liu)的(de)(de)方向(xiang)可(ke)做為一(yi)明顯的(de)(de)識別標準，流(liu)出去的(de)(de)電(dian)(dian)(dian)流(liu)僅(jin)從這(zhe)一(yi)根(gen)(gen)電(dian)(dian)(dian)纜(lan)通(tong)過，所有其(qi)它鄰(lin)近電(dian)(dian)(dian)纜(lan)中(zhong)流(liu)過的(de)(de)都是返(fan)回電(dian)(dian)(dian)流(liu)，但它們的(de)(de)極(ji)性相反。除(chu)了電(dian)(dian)(dian)流(liu)方向(xiang)這(zhe)一(yi)實際差異外，電(dian)(dian)(dian)流(liu)幅度也是一(yi)識別特征，流(liu)出去的(de)(de)電(dian)(dian)(dian)流(liu)僅(jin)通(tong)過一(yi)根(gen)(gen)電(dian)(dian)(dian)纜(lan)、而返(fan)回電(dian)(dian)(dian)流(liu)可(ke)通(tong)過幾根(gen)(gen)電(dian)(dian)(dian)纜(lan)、這(zhe)意味著流(liu)出去的(de)(de)電(dian)(dian)(dian)流(liu)比流(liu)過其(qi)它電(dian)(dian)(dian)纜(lan)的(de)(de)返(fan)回電(dian)(dian)(dian)流(liu)大(da)。

　　接(jie)收機(ji)的(de)(de)任務是探測(ce)流(liu)(liu)(liu)過(guo)電(dian)(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)方(fang)(fang)向(xiang)(xiang)以及它的(de)(de)大小。為達到這一(yi)(yi)目的(de)(de)，電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)傳(chuan)感(gan)器(qi)(qi)被(bei)用作傳(chuan)感(gan)器(qi)(qi)，它帶有(you)(you)一(yi)(yi)放大器(qi)(qi)并(bing)串聯(lian)在電(dian)(dian)(dian)(dian)路中(zhong)，傳(chuan)感(gan)器(qi)(qi)鉗住被(bei)測(ce)電(dian)(dian)(dian)(dian)纜(lan)(lan)，電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)流(liu)(liu)(liu)過(guo)電(dian)(dian)(dian)(dian)纜(lan)(lan)產(chan)生的(de)(de)磁場在傳(chuan)感(gan)器(qi)(qi)的(de)(de)線(xian)圈中(zhong)感(gan)應(ying)出(chu)電(dian)(dian)(dian)(dian)壓(ya)，該電(dian)(dian)(dian)(dian)壓(ya)極(ji)性由電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)方(fang)(fang)向(xiang)(xiang)和傳(chuan)感(gan)器(qi)(qi)線(xian)圈的(de)(de)方(fang)(fang)向(xiang)(xiang)決定(ding)。為了得(de)到明顯(xian)(xian)有(you)(you)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)方(fang)(fang)向(xiang)(xiang)的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)極(ji)性，對一(yi)(yi)束電(dian)(dian)(dian)(dian)纜(lan)(lan)中(zhong)所(suo)(suo)有(you)(you)電(dian)(dian)(dian)(dian)纜(lan)(lan)進行測(ce)試都(dou)采取相(xiang)同正確的(de)(de)方(fang)(fang)向(xiang)(xiang)。傳(chuan)感(gan)器(qi)(qi)線(xian)圈中(zhong)感(gan)應(ying)的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)在表頭中(zhong)顯(xian)(xian)示(shi)出(chu)來，如果傳(chuan)感(gan)器(qi)(qi)按(an)上述方(fang)(fang)式連接(jie)，指(zhi)針擺動(dong)方(fang)(fang)向(xiang)(xiang)可顯(xian)(xian)示(shi)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)方(fang)(fang)向(xiang)(xiang)，即只有(you)(you)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)流(liu)(liu)(liu)出(chu)的(de)(de)這根電(dian)(dian)(dian)(dian)纜(lan)(lan)指(zhi)針向(xiang)(xiang)一(yi)(yi)邊(bian)偏，這根就是要(yao)找(zhao)的(de)(de)電(dian)(dian)(dian)(dian)纜(lan)(lan)。所(suo)(suo)有(you)(you)其它電(dian)(dian)(dian)(dian)纜(lan)(lan)只流(liu)(liu)(liu)過(guo)返回(hui)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，指(zhi)針向(xiang)(xiang)另一(yi)(yi)邊(bian)偏、或無脈動(dong)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，指(zhi)針不偏轉。接(jie)收機(ji)上的(de)(de)放大調(diao)節器(qi)(qi)可調(diao)整信號(hao)強度(du)。

注：1.測試(shi)時電流(liu)鉗上的紅色箭頭標記指向電纜遠端！

2.發射機輸出(chu)電(dian)流(liu)調節大(da)也超不過5A時，應檢查接地電(dian)阻(zu)，也可(ke)另打地釬。【對端(duan)芯(xin)(xin)線接地后，在首(shou)端(duan)測量芯(xin)(xin)地間(jian)電(dian)阻(zu)越(yue)小，輸出(chu)電(dian)流(liu)越(yue)大(da)】
