HTSY電(dian)纜識別儀 電(dian)纜故障檢(jian)測是用(yong)于將某(mou)一(yi)特(te)定電(dian)纜從一(yi)束電(dian)纜中識別出來的儀器(qi)。它(ta)是一(yi)小型化手提式，緊湊型儀器(qi)，裝在鋁合金箱內，由一(yi)個(ge)信(xin)號(hao)發生器(qi)，一(yi)個(ge)帶(dai)卡鉗的接收機及連線構成。

一、HTSY電纜(lan)識別儀 電纜(lan)故障(zhang)檢測工作原理簡介

　　為了可靠準確地識別(bie)(bie)(bie)電(dian)纜，需要(yao)給被(bei)識別(bie)(bie)(bie)電(dian)纜加一特殊的信號(hao)(hao)，該(gai)信號(hao)(hao)要(yao)被(bei)接收(shou)機接收(shou)，利用這一特性便能識別(bie)(bie)(bie)出(chu)要(yao)找(zhao)的電(dian)纜。

該(gai)儀器按下述(shu)原(yuan)理工作：

發生器將周期性的單極性電壓脈沖饋入要識別的電纜中，該電纜需要在遠端接地，以保證有足夠大的電流流過電纜。該系統要設計成返回電流不要從同一電纜中返回，能做到這一點，饋入電纜中的脈沖電流的方向可做為一明顯的識別標準，流出去的電流僅從這一根電纜通過，所有其它鄰近電纜中流過的都是返回電流，但它們的極性相反。除了(le)電(dian)流方(fang)向這(zhe)一實(shi)際差異(yi)外，電(dian)流幅度(du)也是(shi)一識別特征，流出去的(de)電(dian)流僅(jin)通過一根電(dian)纜、而返回電(dian)流可通過幾(ji)根電(dian)纜、這(zhe)意味著流出去的(de)電(dian)流比流過其它電(dian)纜的(de)返回電(dian)流大。

　　接收機的(de)任務是探測流(liu)(liu)(liu)(liu)過(guo)(guo)電(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)方(fang)向(xiang)以及它的(de)大小(xiao)。為(wei)達到這(zhe)(zhe)(zhe)一目的(de)，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)卡鉗(qian)(qian)(qian)被用(yong)作傳感器(qi)，它帶有一放大器(qi)并串聯在電(dian)(dian)(dian)(dian)(dian)路中，卡鉗(qian)(qian)(qian)鉗(qian)(qian)(qian)住被測電(dian)(dian)(dian)(dian)(dian)纜，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)流(liu)(liu)(liu)(liu)過(guo)(guo)電(dian)(dian)(dian)(dian)(dian)纜產生的(de)磁場在卡鉗(qian)(qian)(qian)的(de)線(xian)圈中感應出電(dian)(dian)(dian)(dian)(dian)壓(ya)，該電(dian)(dian)(dian)(dian)(dian)壓(ya)極(ji)性(xing)由電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)方(fang)向(xiang)和卡鉗(qian)(qian)(qian)線(xian)圈的(de)方(fang)向(xiang)決定。為(wei)了得到明顯有電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)方(fang)向(xiang)的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)極(ji)性(xing)，對一束電(dian)(dian)(dian)(dian)(dian)纜中所有電(dian)(dian)(dian)(dian)(dian)纜進行測試都采(cai)取相同正確的(de)繞組方(fang)向(xiang)，這(zhe)(zhe)(zhe)就是卡鉗(qian)(qian)(qian)上標有箭頭的(de)原因(yin)。卡鉗(qian)(qian)(qian)上箭頭的(de)方(fang)向(xiang)應指向(xiang)電(dian)(dian)(dian)(dian)(dian)纜遠(yuan)端，卡鉗(qian)(qian)(qian)線(xian)圈中感應的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)在表頭中顯示出來，如果卡鉗(qian)(qian)(qian)按上述方(fang)式連接，指針(zhen)(zhen)擺動(dong)方(fang)向(xiang)可顯示電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)方(fang)向(xiang)，即只有電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)流(liu)(liu)(liu)(liu)出的(de)這(zhe)(zhe)(zhe)根(gen)電(dian)(dian)(dian)(dian)(dian)纜指針(zhen)(zhen)向(xiang)右偏，這(zhe)(zhe)(zhe)根(gen)就是要找的(de)電(dian)(dian)(dian)(dian)(dian)纜。所有其它電(dian)(dian)(dian)(dian)(dian)纜只流(liu)(liu)(liu)(liu)過(guo)(guo)返回電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，指針(zhen)(zhen)向(xiang)左偏、或無脈動(dong)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，指針(zhen)(zhen)不偏轉。接收機上的(de)放大調節器(qi)可調整(zheng)信號強度(du)。
