高壓帶電電纜識別儀，由信號發生器和接收識別鉗及指示表三部分組成，用接收識別鉗信號檢測器時其它電纜線上檢測到的信號則要小很多且方向相反，通過電表指示幅度及方向，很容易判定被測電纜。

工作原理：

高壓帶電電纜識別儀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。除了電流方向這一實際差異外，電流幅度也是一識別特征，流出去的電流僅通過一根電纜、而返回電流可通過幾根電纜、這意味著流出去的電流比流過其它電纜的返回電流大。

接收機的(de)(de)任務是探測流(liu)(liu)(liu)過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)方(fang)(fang)向(xiang)(xiang)(xiang)(xiang)以及它的(de)(de)大(da)小。為(wei)達(da)到這(zhe)一(yi)(yi)目的(de)(de)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)傳(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)(qi)被用(yong)作傳(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)(qi)，它帶有一(yi)(yi)放(fang)大(da)器(qi)(qi)(qi)并(bing)串聯在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)路中(zhong)，傳(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)(qi)鉗住被測電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)流(liu)(liu)(liu)過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)產生的(de)(de)磁場在(zai)傳(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)(qi)的(de)(de)線圈(quan)(quan)中(zhong)感(gan)(gan)(gan)(gan)應(ying)出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，該電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)極性由電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)方(fang)(fang)向(xiang)(xiang)(xiang)(xiang)和傳(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)(qi)線圈(quan)(quan)的(de)(de)方(fang)(fang)向(xiang)(xiang)(xiang)(xiang)決(jue)定。為(wei)了得到明(ming)顯有電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)方(fang)(fang)向(xiang)(xiang)(xiang)(xiang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)極性，對一(yi)(yi)束電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)中(zhong)所有電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)進行測試都采取(qu)相(xiang)同(tong)正確的(de)(de)方(fang)(fang)向(xiang)(xiang)(xiang)(xiang)。傳(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)(qi)線圈(quan)(quan)中(zhong)感(gan)(gan)(gan)(gan)應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)在(zai)表頭中(zhong)顯示(shi)出來，如果傳(chuan)感(gan)(gan)(gan)(gan)器(qi)(qi)(qi)按上述方(fang)(fang)式連接，指(zhi)(zhi)針擺(bai)動(dong)方(fang)(fang)向(xiang)(xiang)(xiang)(xiang)可(ke)顯示(shi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)方(fang)(fang)向(xiang)(xiang)(xiang)(xiang)，即只有電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)流(liu)(liu)(liu)出的(de)(de)這(zhe)根(gen)(gen)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)指(zhi)(zhi)針向(xiang)(xiang)(xiang)(xiang)一(yi)(yi)邊偏(pian)，這(zhe)根(gen)(gen)就是要找(zhao)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)。所有其(qi)它電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)只流(liu)(liu)(liu)過(guo)返回電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，指(zhi)(zhi)針向(xiang)(xiang)(xiang)(xiang)另(ling)一(yi)(yi)邊偏(pian)、或無脈動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，指(zhi)(zhi)針不偏(pian)轉。接收機上的(de)(de)放(fang)大(da)調(diao)節(jie)器(qi)(qi)(qi)可(ke)調(diao)整信號強度。

操作步驟：

1. 接發射源:

將(jiang)發射卡鉗A的(de)紅、黑兩個(ge)接線插頭(tou)插在(zai)發射源對應(ying)

的(de)(de)(de)兩個紅、黑接線柱上，將(jiang)發(fa)射卡(ka)(ka)鉗(qian)A卡(ka)(ka)在被識別電纜(lan)(lan)(lan)(lan)上。發(fa)射卡(ka)(ka)鉗(qian)A上的(de)(de)(de)箭(jian)頭指(zhi)向電纜(lan)(lan)(lan)(lan)終端。被識別電纜(lan)(lan)(lan)(lan)兩端應可靠接地，對于不(bu)運(yun)行的(de)(de)(de)電纜(lan)(lan)(lan)(lan)，也可以將(jiang)兩端的(de)(de)(de)芯線接地。

2. 打開(kai)發射源和接收(shou)機電源開(kai)關(guan)核對方向:

在距(ju)發(fa)射(she)卡(ka)(ka)鉗(qian)兩(liang)米以外的被識別電(dian)(dian)纜(lan)上，將接(jie)收卡(ka)(ka)鉗(qian)B卡(ka)(ka)住該電(dian)(dian)纜(lan)，其卡(ka)(ka)鉗(qian)上的箭頭(tou)一(yi)定要指向(xiang)(xiang)電(dian)(dian)纜(lan)終(zhong)端(duan)。然后核對電(dian)(dian)流方向(xiang)(xiang)和(he)測試連接(jie)方向(xiang)(xiang)。此時(shi)接(jie)收機電(dian)(dian)流表指針一(yi)定是向(xiang)(xiang)右偏(pian)轉，同(tong)時(shi)有(you)聲光提示(shi)。如圖(tu)所示(shi)。如果將接(jie)收卡(ka)(ka)鉗(qian)B的箭頭(tou)指向(xiang)(xiang)發(fa)射(she)源端(duan)，將不(bu)會有(you)聲光提示(shi)，而且(qie)電(dian)(dian)流表頭(tou)指針向(xiang)(xiang)左偏(pian)轉。記住接(jie)收卡(ka)(ka)鉗(qian)表頭(tou)偏(pian)轉方向(xiang)(xiang)。

3. 識別(bie)(bie):在(zai)識別(bie)(bie)點，用接收(shou)(shou)卡(ka)鉗(qian)B對(dui)各(ge)條(tiao)(tiao)電(dian)(dian)(dian)(dian)纜(lan)進行識別(bie)(bie)。在(zai)進行識別(bie)(bie)時(shi)，一(yi)定要將接收(shou)(shou)卡(ka)鉗(qian)上的箭頭(tou)(tou)始終指向(xiang)(xiang)電(dian)(dian)(dian)(dian)纜(lan)的終端方向(xiang)(xiang)，逐條(tiao)(tiao)電(dian)(dian)(dian)(dian)纜(lan)進行卡(ka)測。在(zai)被識別(bie)(bie)電(dian)(dian)(dian)(dian)纜(lan)上，接收(shou)(shou)機(ji)電(dian)(dian)(dian)(dian)流表(biao)頭(tou)(tou)指針(zhen)一(yi)定是向(xiang)(xiang)右偏(pian)轉(zhuan)，同時(shi)聲光(guang)報(bao)警提(ti)(ti)示(shi)。而在(zai)其余電(dian)(dian)(dian)(dian)纜(lan)上，接收(shou)(shou)機(ji)電(dian)(dian)(dian)(dian)流表(biao)頭(tou)(tou)指針(zhen)一(yi)定是向(xiang)(xiang)左偏(pian)轉(zhuan)，沒有聲光(guang)報(bao)警提(ti)(ti)示(shi)。接收(shou)(shou)機(ji)電(dian)(dian)(dian)(dian)流表(biao)頭(tou)(tou)指針(zhen)向(xiang)(xiang)右偏(pian)轉(zhuan)，同時(shi)聲光(guang)報(bao)警提(ti)(ti)示(shi)的，就是要尋找(zhao)和(he)識別(bie)(bie)的那條(tiao)(tiao)電(dian)(dian)(dian)(dian)纜(lan)。這個測試(shi)結果具有wei一(yi)性。也就是說(shuo)，該(gai)電(dian)(dian)(dian)(dian)纜(lan)溝里(li)無論有多少條(tiao)(tiao)電(dian)(dian)(dian)(dian)纜(lan)，當用接收(shou)(shou)卡(ka)鉗(qian)B對(dui)各(ge)條(tiao)(tiao)電(dian)(dian)(dian)(dian)纜(lan)進行識別(bie)(bie)時(shi)只有一(yi)條(tiao)(tiao)電(dian)(dian)(dian)(dian)纜(lan)(要尋找(zhao)和(he)識別(bie)(bie)的電(dian)(dian)(dian)(dian)纜(lan))上的接收(shou)(shou)機(ji)電(dian)(dian)(dian)(dian)流表(biao)頭(tou)(tou)指針(zhen)是向(xiang)(xiang)右偏(pian)轉(zhuan)，同時(shi)聲光(guang)報(bao)警提(ti)(ti)示(shi)的。
