一、尋線儀是什么

尋線儀是(shi)一種電(dian)工(gong)工(gong)具(ju)，主要用(yong)于準確地(di)定位(wei)地(di)下的電(dian)纜、電(dian)線等物體的位(wei)置(zhi)。設備(bei)由主測試器(qi)，接收器(qi)兩部分(fen)組(zu)成。具(ju)有(you)尋線、對線及線路(lu)(lu)狀態(tai)測試三大功能，具(ju)有(you)快捷、準確的特點，是(shi)通信線路(lu)(lu)，綜(zong)合布(bu)線，線路(lu)(lu)等弱電(dian)系統安裝、維護工(gong)程技術(shu)人員的實用(yong)工(gong)具(ju)。

也廣泛應用(yong)(yong)于(yu)電(dian)話系統、計算機網絡及其它涉(she)及金屬導線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)路等領(ling)域。能夠通過檢(jian)測地下(xia)(xia)(xia)線(xian)(xian)(xian)(xian)(xian)路產(chan)生的(de)(de)磁場變化來(lai)確定線(xian)(xian)(xian)(xian)(xian)路的(de)(de)位(wei)置(zhi)。尋線(xian)(xian)(xian)(xian)(xian)儀可(ke)以(yi)(yi)(yi)將(jiang)隱(yin)藏在地下(xia)(xia)(xia)的(de)(de)電(dian)纜和(he)(he)管線(xian)(xian)(xian)(xian)(xian)的(de)(de)位(wei)置(zhi)信(xin)息轉化成(cheng)具(ju)體的(de)(de)數字信(xin)號，并(bing)可(ke)能通過音、光(guang)等形(xing)式展現出(chu)來(lai)，從而實現檢(jian)測和(he)(he)定位(wei)的(de)(de)目(mu)的(de)(de)。此(ci)外(wai)，尋線(xian)(xian)(xian)(xian)(xian)儀也可(ke)以(yi)(yi)(yi)用(yong)(yong)來(lai)尋找埋在地面以(yi)(yi)(yi)下(xia)(xia)(xia)的(de)(de)電(dian)力線(xian)(xian)(xian)(xian)(xian)、通信(xin)線(xian)(xian)(xian)(xian)(xian)等線(xian)(xian)(xian)(xian)(xian)路，因此(ci)也被稱為地下(xia)(xia)(xia)線(xian)(xian)(xian)(xian)(xian)路探測儀或(huo)(huo)地下(xia)(xia)(xia)線(xian)(xian)(xian)(xian)(xian)路探測器。在實際應用(yong)(yong)中(zhong)，尋線(xian)(xian)(xian)(xian)(xian)儀可(ke)以(yi)(yi)(yi)幫(bang)助(zhu)電(dian)工、工程(cheng)師(shi)或(huo)(huo)其他相關人員在需要(yao)布線(xian)(xian)(xian)(xian)(xian)和(he)(he)維修時(shi)更快更精確地找到所需線(xian)(xian)(xian)(xian)(xian)路，對于(yu)網絡線(xian)(xian)(xian)(xian)(xian)纜、通訊線(xian)(xian)(xian)(xian)(xian)纜、各種金屬線(xian)(xian)(xian)(xian)(xian)路施工工程(cheng)和(he)(he)日(ri)常維護過程(cheng)中(zhong)的(de)(de)查找線(xian)(xian)(xian)(xian)(xian)纜也非常有用(yong)(yong)。

二、尋線儀的工作原理是什么

尋(xun)線(xian)(xian)(xian)(xian)(xian)儀(yi)可以(yi)迅速高效地從(cong)大量的(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)束(shu)線(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)中找(zhao)到(dao)所需線(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)，是網絡線(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)、通(tong)訊線(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)、各種金(jin)屬線(xian)(xian)(xian)(xian)(xian)路(lu)施工(gong)工(gong)程和日常維護過(guo)程中查找(zhao)線(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)的(de)(de)(de)必(bi)備工(gong)具，由信號震蕩(dang)發聲器和尋(xun)線(xian)(xian)(xian)(xian)(xian)器及(ji)相(xiang)應的(de)(de)(de)適配線(xian)(xian)(xian)(xian)(xian)組成，其工(gong)作原理是尋(xun)信號震蕩(dang)發聲器發出(chu)的(de)(de)(de)聲音信號通(tong)過(guo)RJ45/RJ11通(tong)用接口接入目(mu)標線(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)的(de)(de)(de)端口上，至使目(mu)標線(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)回(hui)路(lu)周圍(wei)產生(sheng)一(yi)環繞的(de)(de)(de)聲音信號場(chang)，用高靈敏度感應式尋(xun)線(xian)(xian)(xian)(xian)(xian)儀(yi)很(hen)快(kuai)在回(hui)路(lu)沿途(tu)和未端識(shi)別它發出(chu)的(de)(de)(de)信號場(chang)，從(cong)而找(zhao)到(dao)這條目(mu)的(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)。

尋線儀是利用了(le)感(gan)應尋(xun)線原理來尋(xun)找線纜，所(suo)以(yi)它(ta)不需打(da)開線纜的(de)(de)絕緣層(ceng)，在(zai)線纜外皮上的(de)(de)不同部位(wei)找到(dao)信號。我們可(ke)以(yi)利用這(zhe)一原理在(zai)線纜群束中、地毯下、裝(zhuang)飾墻內、天花板上迅速找到(dao)所(suo)需電纜以(yi)及它(ta)的(de)(de)斷點的(de)(de)大概位(wei)置(zhi)。
