一、尋線儀是什么

尋線儀是(shi)一種電(dian)(dian)工(gong)工(gong)具，主要用于準(zhun)確地(di)定位地(di)下的(de)電(dian)(dian)纜、電(dian)(dian)線等物體的(de)位置。設備由(you)主測試器，接收器兩(liang)部分組(zu)成。具有(you)尋線、對線及線路狀態測試三(san)大功(gong)能，具有(you)快捷、準(zhun)確的(de)特點，是(shi)通信(xin)線路，綜合(he)布(bu)線，線路等弱(ruo)電(dian)(dian)系(xi)統安裝、維(wei)護工(gong)程(cheng)技(ji)術人員(yuan)的(de)實用工(gong)具。

也(ye)廣泛(fan)應用(yong)于電話系統、計算機網(wang)絡及(ji)其它涉及(ji)金(jin)屬(shu)導線(xian)(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)(xian)路等領域。能(neng)(neng)夠通過檢測(ce)(ce)地(di)下(xia)線(xian)(xian)(xian)(xian)(xian)(xian)路產(chan)生的(de)(de)磁場變(bian)化來確定線(xian)(xian)(xian)(xian)(xian)(xian)路的(de)(de)位(wei)(wei)置。尋(xun)線(xian)(xian)(xian)(xian)(xian)(xian)儀可(ke)(ke)以(yi)將隱藏在(zai)地(di)下(xia)的(de)(de)電纜(lan)和管線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)位(wei)(wei)置信息轉化成具體的(de)(de)數字信號(hao)，并可(ke)(ke)能(neng)(neng)通過音(yin)、光等形式展現(xian)出來，從而實現(xian)檢測(ce)(ce)和定位(wei)(wei)的(de)(de)目(mu)的(de)(de)。此外，尋(xun)線(xian)(xian)(xian)(xian)(xian)(xian)儀也(ye)可(ke)(ke)以(yi)用(yong)來尋(xun)找(zhao)埋在(zai)地(di)面以(yi)下(xia)的(de)(de)電力(li)線(xian)(xian)(xian)(xian)(xian)(xian)、通信線(xian)(xian)(xian)(xian)(xian)(xian)等線(xian)(xian)(xian)(xian)(xian)(xian)路，因此也(ye)被稱為(wei)地(di)下(xia)線(xian)(xian)(xian)(xian)(xian)(xian)路探測(ce)(ce)儀或(huo)地(di)下(xia)線(xian)(xian)(xian)(xian)(xian)(xian)路探測(ce)(ce)器。在(zai)實際應用(yong)中，尋(xun)線(xian)(xian)(xian)(xian)(xian)(xian)儀可(ke)(ke)以(yi)幫助電工(gong)、工(gong)程(cheng)師或(huo)其他相關人員在(zai)需要布線(xian)(xian)(xian)(xian)(xian)(xian)和維修時(shi)更快更精確地(di)找(zhao)到所需線(xian)(xian)(xian)(xian)(xian)(xian)路，對于網(wang)絡線(xian)(xian)(xian)(xian)(xian)(xian)纜(lan)、通訊線(xian)(xian)(xian)(xian)(xian)(xian)纜(lan)、各種金(jin)屬(shu)線(xian)(xian)(xian)(xian)(xian)(xian)路施工(gong)工(gong)程(cheng)和日常(chang)(chang)維護過程(cheng)中的(de)(de)查(cha)找(zhao)線(xian)(xian)(xian)(xian)(xian)(xian)纜(lan)也(ye)非常(chang)(chang)有用(yong)。

二、尋線儀的工作原理是什么

尋(xun)(xun)線(xian)(xian)(xian)(xian)儀可以迅速高效地(di)從大量的線(xian)(xian)(xian)(xian)束線(xian)(xian)(xian)(xian)纜(lan)(lan)中(zhong)找到所需線(xian)(xian)(xian)(xian)纜(lan)(lan)，是網絡線(xian)(xian)(xian)(xian)纜(lan)(lan)、通(tong)訊線(xian)(xian)(xian)(xian)纜(lan)(lan)、各種金屬線(xian)(xian)(xian)(xian)路施(shi)工工程和日常維護(hu)過程中(zhong)查找線(xian)(xian)(xian)(xian)纜(lan)(lan)的必(bi)備工具(ju)，由信(xin)(xin)號(hao)震(zhen)蕩發聲(sheng)器和尋(xun)(xun)線(xian)(xian)(xian)(xian)器及相應的適配線(xian)(xian)(xian)(xian)組成(cheng)，其工作原理是尋(xun)(xun)信(xin)(xin)號(hao)震(zhen)蕩發聲(sheng)器發出的聲(sheng)音(yin)信(xin)(xin)號(hao)通(tong)過RJ45/RJ11通(tong)用接口接入目(mu)標線(xian)(xian)(xian)(xian)纜(lan)(lan)的端(duan)口上，至使目(mu)標線(xian)(xian)(xian)(xian)纜(lan)(lan)回(hui)路周圍產(chan)生(sheng)一環繞的聲(sheng)音(yin)信(xin)(xin)號(hao)場(chang)，用高靈敏度感應式尋(xun)(xun)線(xian)(xian)(xian)(xian)儀很快在回(hui)路沿途(tu)和未端(duan)識別(bie)它發出的信(xin)(xin)號(hao)場(chang)，從而找到這(zhe)條目(mu)的線(xian)(xian)(xian)(xian)纜(lan)(lan)。

尋線儀是利(li)用(yong)了感應尋線(xian)(xian)原理來尋找線(xian)(xian)纜(lan)(lan)，所以它不(bu)需打開線(xian)(xian)纜(lan)(lan)的(de)絕緣層，在線(xian)(xian)纜(lan)(lan)外皮上的(de)不(bu)同(tong)部位找到信號。我們可以利(li)用(yong)這一原理在線(xian)(xian)纜(lan)(lan)群束中、地毯下、裝飾(shi)墻內、天花板上迅(xun)速找到所需電纜(lan)(lan)以及它的(de)斷點的(de)大概位置。
