帶電電纜識別儀廠家是用于將某一(yi)特定(ding)電(dian)纜從一(yi)束電(dian)纜中識別出來的儀(yi)器。它是一(yi)小型化手(shou)提(ti)式，緊湊型儀(yi)器，裝在鋁合(he)金(jin)箱內，由一(yi)個信號發生器，一(yi)個帶(dai)傳感器的接收機及連線構成。

帶電電纜識別儀廠家簡介：為了可靠(kao)準確地識(shi)別(bie)電纜，需要(yao)給被識(shi)別(bie)電纜加一(yi)(yi)特殊的(de)信號(hao)，該(gai)信號(hao)要(yao)被接(jie)收機(ji)接(jie)收，利用這一(yi)(yi)特性便能識(shi)別(bie)出要(yao)找的(de)電纜。

工作原理：

發生(sheng)器(qi)將周(zhou)期性(xing)(xing)的(de)(de)單極(ji)性(xing)(xing)電(dian)(dian)(dian)(dian)(dian)壓脈(mo)沖饋入要(yao)(yao)識別(bie)的(de)(de)電(dian)(dian)(dian)(dian)(dian)纜中(zhong)(zhong)，該電(dian)(dian)(dian)(dian)(dian)纜需要(yao)(yao)在遠(yuan)端接地，以保證有足夠大的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)流(liu)(liu)過電(dian)(dian)(dian)(dian)(dian)纜。該系統(tong)要(yao)(yao)設(she)計成返(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不要(yao)(yao)從(cong)同(tong)一(yi)(yi)電(dian)(dian)(dian)(dian)(dian)纜中(zhong)(zhong)返(fan)回(hui)(hui)，能(neng)做到這(zhe)一(yi)(yi)點，饋入電(dian)(dian)(dian)(dian)(dian)纜中(zhong)(zhong)的(de)(de)脈(mo)沖電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)方(fang)向(xiang)可(ke)做為(wei)一(yi)(yi)明顯的(de)(de)識別(bie)標準，流(liu)(liu)出去(qu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)僅從(cong)這(zhe)一(yi)(yi)根(gen)電(dian)(dian)(dian)(dian)(dian)纜通(tong)過，所有其它(ta)鄰近電(dian)(dian)(dian)(dian)(dian)纜中(zhong)(zhong)流(liu)(liu)過的(de)(de)都是返(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，但它(ta)們(men)的(de)(de)極(ji)性(xing)(xing)相反。除了電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)方(fang)向(xiang)這(zhe)一(yi)(yi)實際差異外，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)幅度也是一(yi)(yi)識別(bie)特(te)征(zheng)，流(liu)(liu)出去(qu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)僅通(tong)過一(yi)(yi)根(gen)電(dian)(dian)(dian)(dian)(dian)纜、而(er)返(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)可(ke)通(tong)過幾根(gen)電(dian)(dian)(dian)(dian)(dian)纜、這(zhe)意味著(zhu)流(liu)(liu)出去(qu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)比流(liu)(liu)過其它(ta)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)返(fan)回(hui)(hui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大。

　　接收(shou)機的(de)任(ren)務是探測流(liu)過電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)方(fang)向以及(ji)它(ta)的(de)大(da)小。為達到(dao)這一目的(de)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)被用作傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)，它(ta)帶有(you)一放大(da)器(qi)(qi)并串(chuan)聯在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)路中，傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)鉗住(zhu)被測電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)流(liu)過電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)產生的(de)磁場在(zai)傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)的(de)線圈(quan)中感(gan)(gan)(gan)應出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，該電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)極(ji)性由(you)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)方(fang)向和傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)線圈(quan)的(de)方(fang)向決定。為了得到(dao)明(ming)顯(xian)有(you)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)方(fang)向的(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)極(ji)性，對一束電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中所(suo)有(you)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)進行測試都采取(qu)相(xiang)同正確(que)的(de)方(fang)向。傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)線圈(quan)中感(gan)(gan)(gan)應的(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)在(zai)表頭中顯(xian)示出(chu)來，如果傳(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)按上述方(fang)式連接，指(zhi)針(zhen)擺動(dong)方(fang)向可顯(xian)示電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)方(fang)向，即只有(you)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)流(liu)出(chu)的(de)這根電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)指(zhi)針(zhen)向一邊偏，這根就是要找的(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。所(suo)有(you)其它(ta)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)只流(liu)過返(fan)回(hui)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，指(zhi)針(zhen)向另(ling)一邊偏、或無脈動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，指(zhi)針(zhen)不偏轉。接收(shou)機上的(de)放大(da)調節器(qi)(qi)可調整信號(hao)強度。

注：1.測試時電流鉗上的紅(hong)色箭(jian)頭標記指向電纜遠端！

2.發(fa)射(she)機輸出(chu)電流調節大(da)也超不過5A時(shi)，應檢查(cha)接地(di)(di)電阻，也可另(ling)打地(di)(di)釬。【對端(duan)芯線接地(di)(di)后，在首端(duan)測量芯地(di)(di)間電阻越小(xiao)，輸出(chu)電流越大(da)】
