電纜識別儀價格是用于將某(mou)一(yi)特定電纜從一(yi)束電纜中識(shi)別出來的(de)(de)儀器。它是一(yi)小型化手提式，緊湊型儀器，裝在鋁合金箱內，由(you)一(yi)個信(xin)號發生器，一(yi)個帶傳(chuan)感器的(de)(de)接收機(ji)及連線構成。

電纜識別儀價格簡介(jie)：為(wei)了可靠準確地識別電纜(lan)，需要給被識別電纜(lan)加一特(te)殊的信(xin)號(hao)，該(gai)信(xin)號(hao)要被接收機(ji)接收，利用這一特(te)性便能(neng)識別出要找(zhao)的電纜(lan)。

工作原理：

發生器(qi)將周(zhou)期性(xing)的(de)(de)(de)單極性(xing)電(dian)(dian)(dian)(dian)(dian)(dian)壓脈(mo)沖(chong)饋入要識(shi)(shi)別(bie)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中，該(gai)(gai)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)需(xu)要在遠端接地(di)，以保證有足夠大的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)流(liu)(liu)過電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。該(gai)(gai)系(xi)統(tong)要設(she)計(ji)成返回電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不要從(cong)同一(yi)(yi)(yi)(yi)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中返回，能做到(dao)這一(yi)(yi)(yi)(yi)點，饋入電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中的(de)(de)(de)脈(mo)沖(chong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)方向可(ke)做為一(yi)(yi)(yi)(yi)明顯(xian)的(de)(de)(de)識(shi)(shi)別(bie)標準，流(liu)(liu)出去的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)僅從(cong)這一(yi)(yi)(yi)(yi)根(gen)(gen)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)通過，所有其它鄰近電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中流(liu)(liu)過的(de)(de)(de)都(dou)是(shi)返回電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，但它們(men)的(de)(de)(de)極性(xing)相反。除了電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)方向這一(yi)(yi)(yi)(yi)實際差異(yi)外(wai)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)幅度也是(shi)一(yi)(yi)(yi)(yi)識(shi)(shi)別(bie)特征(zheng)，流(liu)(liu)出去的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)僅通過一(yi)(yi)(yi)(yi)根(gen)(gen)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)、而返回電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)可(ke)通過幾根(gen)(gen)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)、這意味著流(liu)(liu)出去的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)比流(liu)(liu)過其它電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)返回電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大。

　　接(jie)收(shou)機的(de)(de)(de)(de)任(ren)務是探測(ce)流(liu)(liu)過電(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)流(liu)(liu)方(fang)(fang)(fang)向(xiang)(xiang)以及它(ta)的(de)(de)(de)(de)大小。為(wei)達(da)到這一目的(de)(de)(de)(de)，電(dian)(dian)(dian)(dian)流(liu)(liu)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)被用作傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)，它(ta)帶(dai)有(you)一放大器(qi)(qi)并(bing)串(chuan)聯在電(dian)(dian)(dian)(dian)路(lu)中，傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)鉗住被測(ce)電(dian)(dian)(dian)(dian)纜，電(dian)(dian)(dian)(dian)流(liu)(liu)流(liu)(liu)過電(dian)(dian)(dian)(dian)纜產生的(de)(de)(de)(de)磁(ci)場(chang)在傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)的(de)(de)(de)(de)線圈(quan)中感(gan)應出電(dian)(dian)(dian)(dian)壓，該電(dian)(dian)(dian)(dian)壓極性(xing)由(you)電(dian)(dian)(dian)(dian)流(liu)(liu)方(fang)(fang)(fang)向(xiang)(xiang)和傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)線圈(quan)的(de)(de)(de)(de)方(fang)(fang)(fang)向(xiang)(xiang)決定。為(wei)了得到明顯有(you)電(dian)(dian)(dian)(dian)流(liu)(liu)方(fang)(fang)(fang)向(xiang)(xiang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓極性(xing)，對一束電(dian)(dian)(dian)(dian)纜中所(suo)有(you)電(dian)(dian)(dian)(dian)纜進行測(ce)試都采取相同正確的(de)(de)(de)(de)方(fang)(fang)(fang)向(xiang)(xiang)。傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)線圈(quan)中感(gan)應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓在表頭中顯示出來，如果傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)按上述方(fang)(fang)(fang)式連(lian)接(jie)，指針擺動(dong)方(fang)(fang)(fang)向(xiang)(xiang)可顯示電(dian)(dian)(dian)(dian)流(liu)(liu)方(fang)(fang)(fang)向(xiang)(xiang)，即只有(you)電(dian)(dian)(dian)(dian)流(liu)(liu)流(liu)(liu)出的(de)(de)(de)(de)這根(gen)電(dian)(dian)(dian)(dian)纜指針向(xiang)(xiang)一邊偏(pian)，這根(gen)就(jiu)是要找的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)纜。所(suo)有(you)其它(ta)電(dian)(dian)(dian)(dian)纜只流(liu)(liu)過返(fan)回電(dian)(dian)(dian)(dian)流(liu)(liu)，指針向(xiang)(xiang)另一邊偏(pian)、或無脈動(dong)電(dian)(dian)(dian)(dian)流(liu)(liu)，指針不(bu)偏(pian)轉。接(jie)收(shou)機上的(de)(de)(de)(de)放大調節(jie)器(qi)(qi)可調整(zheng)信號(hao)強度。

3.　保(bao)險(xian)座：儀器使(shi)用10A保(bao)險(xian)芯，損壞時應換(huan)同(tong)規格保(bao)險(xian)芯。

4.　黑接線柱(zhu)：測(ce)試(shi)(shi)時，用(yong)配套黑色(se)測(ce)試(shi)(shi)線（Ф4插(cha)頭(tou)）插(cha)入此(ci)插(cha)孔，另一端測(ce)試(shi)(shi)夾接系統地。

5.　紅接線柱：測試時，用配套紅色(se)測試線（Ф4插(cha)頭）插(cha)入此插(cha)孔，另一端測試夾接被測電纜芯線。

6.　表頭：指示輸出(chu)(chu)電流(liu)大小(xiao)。7.輸出(chu)(chu)調(diao)節；調(diao)節輸出(chu)(chu)電流(liu)大小(xiao)。

7、輸出調節(jie)旋鈕：用于輸出幅度大小的(de)調節(jie)。以(yi)不滿(man)刻度打表為原則。

接(jie)收機各部(bu)分功能如下：

1. 靈敏度調(diao)節：順(shun)時針(zhen)旋轉，接收(shou)機電表指示值增大(da)，逆時針(zhen)旋轉，指示值變小(xiao)。

2. 表頭(tou)：指示輸入(ru)信號幅度大(da)小與(yu)極性。

三、工作方法

帶電(dian)(dian)(dian)電(dian)(dian)(dian)纜(lan)設備儀信(xin)號(hao)發(fa)生(sheng)器由(you)交流電(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)，它對(dui)已斷(duan)電(dian)(dian)(dian)的(de)、要識別(bie)的(de)電(dian)(dian)(dian)纜(lan)加上固定周期(qi)單極性(xing)的(de)直流脈(mo)沖(chong)。工(gong)作(zuo)時，將發(fa)生(sheng)器輸出線連在電(dian)(dian)(dian)纜(lan)芯(xin)線和接(jie)地(di)點(dian)或地(di)釘上，該電(dian)(dian)(dian)纜(lan)線鎧(kai)裝與大(da)地(di)斷(duan)開(kai)，芯(xin)線在遠端與接(jie)地(di)點(dian)或地(di)釘相連，該回路(lu)可傳(chuan)導脈(mo)沖(chong)電(dian)(dian)(dian)流，它可由(you)識別(bie)儀上的(de)表頭讀出，電(dian)(dian)(dian)流大(da)小由(you)環(huan)路(lu)電(dian)(dian)(dian)阻決(jue)定，環(huan)路(lu)電(dian)(dian)(dian)阻應盡可能小。

為(wei)保(bao)證(zheng)環路電(dian)阻的(de)阻抗盡(jin)可能低，地(di)釘(ding)與地(di)之間要保(bao)證(zheng)接(jie)觸(chu)良好（將地(di)釘(ding)附近(jin)的(de)地(di)方弄濕(shi)）。發射(she)機(ji)與電(dian)纜(lan)連接(jie)正確(que)但(dan)無輸出，說明(ming)環路電(dian)阻太大或未構成測試(shi)回路，應檢查終端(duan)接(jie)地(di)。【將發射(she)機(ji)兩輸出夾短接(jie)，表頭(tou)有輸出，證(zheng)明(ming)儀器完好】警告：為(wei)確(que)保(bao)人身安全，對已確(que)定(ding)的(de)電(dian)纜(lan)，在維(wei)修開鋸前，一定(ding)要進行扎釘(ding)試(shi)驗，可選DS1102型電(dian)纜(lan)安全刺(ci)扎器。

注：1.測試時電流鉗上的紅色箭頭標(biao)記(ji)指(zhi)向電纜遠(yuan)端！

2.發射機輸出電流調節大也(ye)超不過5A時(shi)，應(ying)檢查接(jie)地(di)(di)電阻，也(ye)可另(ling)打地(di)(di)釬。【對端(duan)芯線接(jie)地(di)(di)后(hou)，在首端(duan)測量芯地(di)(di)間電阻越(yue)(yue)小，輸出電流越(yue)(yue)大】
