標題：全自動電纜識別檢測儀

產品概述

產品(pin)介紹：

全自動電纜識別檢測儀是我司根據電力行業的需要而研制的一種儀器。中試高測電纜識別儀在電力電纜架設、遷移、維護以及故障處理中用來判別一束電纜中欲尋找的一根特定的電纜；具有判別電纜準確（方向及幅度的雙重判別）、快速、操作簡單、應用范圍廣等特點。是目前國內同類儀器中技術*、性能較*的新型儀器。 

電(dian)纜(lan)識(shi)(shi)別儀由(you)信號發生器(qi)和(he)接收識(shi)(shi)別鉗(qian)(qian)及(ji)指示(shi)(shi)表(biao)三部分組(zu)成，用接收識(shi)(shi)別鉗(qian)(qian)信號檢測(ce)器(qi)時其它電(dian)纜(lan)線(xian)上(shang)檢測(ce)到的信號則(ze)要(yao)小很(hen)多且(qie)方(fang)向相反，通過(guo)電(dian)表(biao)指示(shi)(shi)幅(fu)度及(ji)方(fang)向，很(hen)容易判定被測(ce)電(dian)纜(lan)。

工作原理：

電纜識別(bie)檢測儀(yi)，為了可靠(kao)準確地(di)識別(bie)電纜，需要給被(bei)識別(bie)電纜加(jia)一特殊的信(xin)號(hao)，該信(xin)號(hao)要被(bei)接(jie)收機接(jie)收，利用這(zhe)一特性便能識別(bie)出要找(zhao)的電纜。

發生器將(jiang)周期性(xing)的(de)(de)(de)單極性(xing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓脈沖饋入(ru)要(yao)(yao)識(shi)別的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中，該(gai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)需要(yao)(yao)在遠端接(jie)地，以(yi)保(bao)證有足夠(gou)大的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)流(liu)(liu)(liu)過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。該(gai)系統要(yao)(yao)設(she)計成返(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)不要(yao)(yao)從同一(yi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中返(fan)回(hui)(hui)，能做到(dao)這一(yi)點(dian)，饋入(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中的(de)(de)(de)脈沖電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)(de)方(fang)向可做為(wei)一(yi)明顯的(de)(de)(de)識(shi)別標準(zhun)，流(liu)(liu)(liu)出(chu)去(qu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)僅(jin)從這一(yi)根(gen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)通(tong)過(guo)，所有其它(ta)鄰近電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中流(liu)(liu)(liu)過(guo)的(de)(de)(de)都是(shi)返(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，但(dan)它(ta)們的(de)(de)(de)極性(xing)相反(fan)。除了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)方(fang)向這一(yi)實際(ji)差異外(wai)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)幅度也是(shi)一(yi)識(shi)別特(te)征，流(liu)(liu)(liu)出(chu)去(qu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)僅(jin)通(tong)過(guo)一(yi)根(gen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)、而返(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)可通(tong)過(guo)幾根(gen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)、這意味著流(liu)(liu)(liu)出(chu)去(qu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)比流(liu)(liu)(liu)過(guo)其它(ta)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)返(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大。

全自動電纜識別檢測儀，為了得到明顯有電流方向的電壓極性，對一束電纜中所有電纜進行測試都采取相同正確的繞組方向，這就是卡鉗上標有箭頭的原因。卡鉗上箭頭的方向應指向電纜遠端，卡鉗線圈中感應的電壓在表頭中顯示出來，如果卡鉗按上述方式連接，指針擺動方向可顯示電流方向，即只有電流流出的這根電纜指針向右偏，這根就是要找的電纜。所有其它電纜只流過返回電流，指針向左偏、或無脈動電流，指針不偏轉。接收機上的放大調節器可調整信號強度。
