電纜識別儀廠家是(shi)用(yong)于將(jiang)某(mou)一(yi)特(te)定電纜從一(yi)束電纜中識(shi)別出來(lai)的儀器。它是(shi)一(yi)小型(xing)化手提(ti)式，緊(jin)湊型(xing)儀器，裝(zhuang)在(zai)鋁合(he)金箱內，由一(yi)個信(xin)號發生器，一(yi)個帶傳(chuan)感器的接收(shou)機及(ji)連線構成。

電纜識別儀廠家簡介：為了(le)可(ke)靠準確地(di)識別(bie)電纜(lan)，需要給被識別(bie)電纜(lan)加一特殊(shu)的(de)信號，該信號要被接(jie)收機接(jie)收，利(li)用這一特性便能識別(bie)出要找的(de)電纜(lan)。

工作原理：

發(fa)生器將周期性(xing)的(de)(de)單(dan)極性(xing)電(dian)(dian)(dian)(dian)(dian)壓脈(mo)沖饋入(ru)要識別的(de)(de)電(dian)(dian)(dian)(dian)(dian)纜(lan)中(zhong)，該電(dian)(dian)(dian)(dian)(dian)纜(lan)需要在遠(yuan)端接(jie)地(di)，以保證有足夠大(da)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)流(liu)(liu)過電(dian)(dian)(dian)(dian)(dian)纜(lan)。該系統要設(she)計成返(fan)回電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不要從同(tong)一電(dian)(dian)(dian)(dian)(dian)纜(lan)中(zhong)返(fan)回，能(neng)做(zuo)到這一點，饋入(ru)電(dian)(dian)(dian)(dian)(dian)纜(lan)中(zhong)的(de)(de)脈(mo)沖電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)方(fang)向可做(zuo)為一明顯(xian)的(de)(de)識別標準，流(liu)(liu)出去(qu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)僅從這一根電(dian)(dian)(dian)(dian)(dian)纜(lan)通(tong)(tong)過，所有其它鄰(lin)近電(dian)(dian)(dian)(dian)(dian)纜(lan)中(zhong)流(liu)(liu)過的(de)(de)都(dou)是返(fan)回電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，但它們的(de)(de)極性(xing)相反。除了(le)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)方(fang)向這一實際(ji)差異(yi)外，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)幅度(du)也是一識別特征，流(liu)(liu)出去(qu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)僅通(tong)(tong)過一根電(dian)(dian)(dian)(dian)(dian)纜(lan)、而返(fan)回電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)可通(tong)(tong)過幾(ji)根電(dian)(dian)(dian)(dian)(dian)纜(lan)、這意味(wei)著流(liu)(liu)出去(qu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)比(bi)流(liu)(liu)過其它電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)返(fan)回電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)。

　　接(jie)(jie)收機的(de)(de)任(ren)務是(shi)探測流(liu)過(guo)電(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)流(liu)方(fang)向(xiang)以及(ji)它的(de)(de)大(da)小(xiao)。為達到這一目(mu)的(de)(de)，電(dian)(dian)(dian)(dian)流(liu)傳(chuan)感(gan)(gan)(gan)器被(bei)用作(zuo)傳(chuan)感(gan)(gan)(gan)器，它帶有一放大(da)器并(bing)串聯在(zai)電(dian)(dian)(dian)(dian)路(lu)中，傳(chuan)感(gan)(gan)(gan)器鉗住被(bei)測電(dian)(dian)(dian)(dian)纜，電(dian)(dian)(dian)(dian)流(liu)流(liu)過(guo)電(dian)(dian)(dian)(dian)纜產生的(de)(de)磁場在(zai)傳(chuan)感(gan)(gan)(gan)器的(de)(de)線(xian)圈中感(gan)(gan)(gan)應出(chu)(chu)電(dian)(dian)(dian)(dian)壓，該電(dian)(dian)(dian)(dian)壓極(ji)性(xing)由電(dian)(dian)(dian)(dian)流(liu)方(fang)向(xiang)和傳(chuan)感(gan)(gan)(gan)器線(xian)圈的(de)(de)方(fang)向(xiang)決(jue)定。為了得到明顯(xian)有電(dian)(dian)(dian)(dian)流(liu)方(fang)向(xiang)的(de)(de)電(dian)(dian)(dian)(dian)壓極(ji)性(xing)，對一束電(dian)(dian)(dian)(dian)纜中所(suo)有電(dian)(dian)(dian)(dian)纜進行測試都采取(qu)相(xiang)同正確(que)的(de)(de)方(fang)向(xiang)。傳(chuan)感(gan)(gan)(gan)器線(xian)圈中感(gan)(gan)(gan)應的(de)(de)電(dian)(dian)(dian)(dian)壓在(zai)表頭中顯(xian)示出(chu)(chu)來，如果傳(chuan)感(gan)(gan)(gan)器按上述方(fang)式連接(jie)(jie)，指針擺動方(fang)向(xiang)可(ke)顯(xian)示電(dian)(dian)(dian)(dian)流(liu)方(fang)向(xiang)，即只有電(dian)(dian)(dian)(dian)流(liu)流(liu)出(chu)(chu)的(de)(de)這根電(dian)(dian)(dian)(dian)纜指針向(xiang)一邊偏(pian)，這根就是(shi)要(yao)找的(de)(de)電(dian)(dian)(dian)(dian)纜。所(suo)有其它電(dian)(dian)(dian)(dian)纜只流(liu)過(guo)返回(hui)電(dian)(dian)(dian)(dian)流(liu)，指針向(xiang)另一邊偏(pian)、或無脈動電(dian)(dian)(dian)(dian)流(liu)，指針不(bu)偏(pian)轉。接(jie)(jie)收機上的(de)(de)放大(da)調節器可(ke)調整信號強度。

6.　表頭：指(zhi)示輸(shu)出電(dian)流大小(xiao)。7.輸(shu)出調(diao)節；調(diao)節輸(shu)出電(dian)流大小(xiao)。

7、輸出調節旋鈕：用于(yu)輸出幅度(du)(du)大小(xiao)的調節。以不滿刻(ke)度(du)(du)打表(biao)為原則。

接收(shou)機各部(bu)分功能如下：

1. 靈(ling)敏度調節：順(shun)時(shi)針(zhen)旋轉(zhuan)，接(jie)收(shou)機電表指示值增大，逆(ni)時(shi)針(zhen)旋轉(zhuan)，指示值變小。

2. 表頭：指示輸入信號幅(fu)度大小與(yu)極性。

三、工作方法

帶電(dian)(dian)(dian)電(dian)(dian)(dian)纜(lan)設備儀信號發(fa)生(sheng)器(qi)由(you)交(jiao)流(liu)電(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)，它對已斷(duan)電(dian)(dian)(dian)的、要(yao)識(shi)別的電(dian)(dian)(dian)纜(lan)加(jia)上(shang)(shang)固定周期(qi)單極性的直流(liu)脈(mo)沖。工作時，將發(fa)生(sheng)器(qi)輸出線(xian)連(lian)在電(dian)(dian)(dian)纜(lan)芯(xin)線(xian)和接地(di)(di)(di)點(dian)或地(di)(di)(di)釘上(shang)(shang)，該電(dian)(dian)(dian)纜(lan)線(xian)鎧裝(zhuang)與大地(di)(di)(di)斷(duan)開，芯(xin)線(xian)在遠端與接地(di)(di)(di)點(dian)或地(di)(di)(di)釘相(xiang)連(lian)，該回(hui)路(lu)可傳(chuan)導(dao)脈(mo)沖電(dian)(dian)(dian)流(liu)，它可由(you)識(shi)別儀上(shang)(shang)的表頭讀(du)出，電(dian)(dian)(dian)流(liu)大小(xiao)由(you)環路(lu)電(dian)(dian)(dian)阻決定，環路(lu)電(dian)(dian)(dian)阻應盡可能小(xiao)。

為(wei)保證環路(lu)(lu)電(dian)阻(zu)的(de)阻(zu)抗(kang)盡可(ke)能低，地(di)釘(ding)與(yu)地(di)之間要保證接(jie)觸良(liang)好（將地(di)釘(ding)附近的(de)地(di)方弄濕）。發(fa)射機與(yu)電(dian)纜連接(jie)正確(que)但無輸出(chu)，說明環路(lu)(lu)電(dian)阻(zu)太大(da)或未構成測試回路(lu)(lu)，應(ying)檢查終端接(jie)地(di)。【將發(fa)射機兩輸出(chu)夾短(duan)接(jie)，表頭有(you)輸出(chu)，證明儀器(qi)完好】警告：為(wei)確(que)保人(ren)身安(an)全(quan)，對已(yi)確(que)定的(de)電(dian)纜，在維修開(kai)鋸前，一定要進行扎(zha)釘(ding)試驗，可(ke)選DS1102型電(dian)纜安(an)全(quan)刺扎(zha)器(qi)。
