電纜識別儀報價是用于(yu)將某一特(te)定電纜從一束電纜中識別(bie)出來的儀(yi)器(qi)(qi)。它(ta)是一小型化(hua)手提式，緊湊(cou)型儀(yi)器(qi)(qi)，裝在鋁合金箱內，由一個信號發生器(qi)(qi)，一個帶傳感器(qi)(qi)的接收機(ji)及連線構成。

電纜識別儀報價簡介：為了可靠準確地(di)識別電纜(lan)，需要(yao)給被識別電纜(lan)加一(yi)特(te)殊(shu)的信號，該信號要(yao)被接收(shou)(shou)機接收(shou)(shou)，利(li)用這一(yi)特(te)性便能識別出要(yao)找的電纜(lan)。

三、工作方法

帶電(dian)(dian)電(dian)(dian)纜設備儀信號發生器由(you)(you)交流(liu)電(dian)(dian)源供電(dian)(dian)，它對已斷電(dian)(dian)的(de)、要(yao)識別的(de)電(dian)(dian)纜加上固定周期單極性(xing)的(de)直(zhi)流(liu)脈沖(chong)。工作時，將(jiang)發生器輸出線連在(zai)電(dian)(dian)纜芯(xin)線和(he)接地點(dian)或(huo)地釘上，該電(dian)(dian)纜線鎧裝與(yu)大地斷開，芯(xin)線在(zai)遠端與(yu)接地點(dian)或(huo)地釘相連，該回路可(ke)傳導脈沖(chong)電(dian)(dian)流(liu)，它可(ke)由(you)(you)識別儀上的(de)表頭讀出，電(dian)(dian)流(liu)大小(xiao)由(you)(you)環路電(dian)(dian)阻決定，環路電(dian)(dian)阻應(ying)盡可(ke)能小(xiao)。

為(wei)(wei)保(bao)證(zheng)環(huan)路電阻(zu)的阻(zu)抗盡可能低，地釘(ding)與地之間要(yao)保(bao)證(zheng)接(jie)觸良好（將(jiang)(jiang)地釘(ding)附近(jin)的地方(fang)弄濕）。發射機(ji)與電纜連接(jie)正確(que)但(dan)無輸出(chu)(chu)，說明環(huan)路電阻(zu)太(tai)大或未構成測(ce)試回(hui)路，應檢(jian)查終端接(jie)地。【將(jiang)(jiang)發射機(ji)兩輸出(chu)(chu)夾(jia)短接(jie)，表(biao)頭(tou)有輸出(chu)(chu)，證(zheng)明儀器(qi)完好】警告：為(wei)(wei)確(que)保(bao)人身安(an)全，對已確(que)定(ding)的電纜，在(zai)維(wei)修開鋸前，一定(ding)要(yao)進(jin)行扎(zha)釘(ding)試驗(yan)，可選DS1102型電纜安(an)全刺扎(zha)器(qi)。
