一、尋線儀是什么

尋線儀是一種電(dian)(dian)工(gong)(gong)工(gong)(gong)具，主(zhu)要用于(yu)準(zhun)確(que)地定位地下(xia)的電(dian)(dian)纜、電(dian)(dian)線(xian)(xian)等物體的位置。設備由(you)主(zhu)測(ce)試(shi)(shi)器(qi)，接收器(qi)兩部分組(zu)成。具有尋線(xian)(xian)、對線(xian)(xian)及(ji)線(xian)(xian)路狀態(tai)測(ce)試(shi)(shi)三大(da)功能，具有快捷、準(zhun)確(que)的特點(dian)，是通信線(xian)(xian)路，綜合(he)布線(xian)(xian)，線(xian)(xian)路等弱電(dian)(dian)系統安裝、維(wei)護工(gong)(gong)程技術人員的實用工(gong)(gong)具。

也廣泛(fan)應用(yong)于電(dian)(dian)話系統(tong)、計(ji)算機網絡(luo)及其(qi)它涉及金(jin)屬導線(xian)(xian)(xian)線(xian)(xian)(xian)路(lu)等領域。能(neng)夠通(tong)過檢測地下(xia)線(xian)(xian)(xian)路(lu)產生的(de)磁場變(bian)化來(lai)確定線(xian)(xian)(xian)路(lu)的(de)位置(zhi)。尋(xun)線(xian)(xian)(xian)儀(yi)(yi)可(ke)(ke)(ke)以(yi)將(jiang)隱藏(zang)在(zai)地下(xia)的(de)電(dian)(dian)纜(lan)和(he)管線(xian)(xian)(xian)的(de)位置(zhi)信息轉(zhuan)化成具體(ti)的(de)數字信號，并可(ke)(ke)(ke)能(neng)通(tong)過音、光等形式展現(xian)出(chu)來(lai)，從而實現(xian)檢測和(he)定位的(de)目(mu)的(de)。此(ci)(ci)外，尋(xun)線(xian)(xian)(xian)儀(yi)(yi)也可(ke)(ke)(ke)以(yi)用(yong)來(lai)尋(xun)找(zhao)(zhao)埋在(zai)地面以(yi)下(xia)的(de)電(dian)(dian)力線(xian)(xian)(xian)、通(tong)信線(xian)(xian)(xian)等線(xian)(xian)(xian)路(lu)，因此(ci)(ci)也被稱為地下(xia)線(xian)(xian)(xian)路(lu)探測儀(yi)(yi)或(huo)地下(xia)線(xian)(xian)(xian)路(lu)探測器。在(zai)實際應用(yong)中(zhong)，尋(xun)線(xian)(xian)(xian)儀(yi)(yi)可(ke)(ke)(ke)以(yi)幫助電(dian)(dian)工(gong)、工(gong)程(cheng)師或(huo)其(qi)他相(xiang)關人員在(zai)需(xu)要布線(xian)(xian)(xian)和(he)維修(xiu)時(shi)更(geng)快更(geng)精確地找(zhao)(zhao)到所需(xu)線(xian)(xian)(xian)路(lu)，對于網絡(luo)線(xian)(xian)(xian)纜(lan)、通(tong)訊(xun)線(xian)(xian)(xian)纜(lan)、各種金(jin)屬線(xian)(xian)(xian)路(lu)施工(gong)工(gong)程(cheng)和(he)日(ri)常(chang)維護過程(cheng)中(zhong)的(de)查找(zhao)(zhao)線(xian)(xian)(xian)纜(lan)也非常(chang)有用(yong)。

二、尋線儀的工作原理是什么

尋(xun)(xun)線(xian)(xian)儀(yi)可以(yi)迅速高效(xiao)地從(cong)大(da)量的(de)(de)(de)線(xian)(xian)束線(xian)(xian)纜(lan)(lan)中找(zhao)到所(suo)需線(xian)(xian)纜(lan)(lan)，是網(wang)絡線(xian)(xian)纜(lan)(lan)、通(tong)訊線(xian)(xian)纜(lan)(lan)、各種金屬線(xian)(xian)路施工工程和(he)日常維(wei)護過程中查找(zhao)線(xian)(xian)纜(lan)(lan)的(de)(de)(de)必(bi)備工具，由(you)信(xin)號震蕩發聲(sheng)器和(he)尋(xun)(xun)線(xian)(xian)器及(ji)相應的(de)(de)(de)適配線(xian)(xian)組成(cheng)，其工作原理是尋(xun)(xun)信(xin)號震蕩發聲(sheng)器發出的(de)(de)(de)聲(sheng)音信(xin)號通(tong)過RJ45/RJ11通(tong)用接口接入(ru)目標線(xian)(xian)纜(lan)(lan)的(de)(de)(de)端口上，至使目標線(xian)(xian)纜(lan)(lan)回路周圍產生一環繞的(de)(de)(de)聲(sheng)音信(xin)號場，用高靈敏度感應式(shi)尋(xun)(xun)線(xian)(xian)儀(yi)很快在回路沿途和(he)未端識別它發出的(de)(de)(de)信(xin)號場，從(cong)而找(zhao)到這條目的(de)(de)(de)線(xian)(xian)纜(lan)(lan)。

尋線儀是利用了感應尋線(xian)(xian)(xian)原(yuan)理來尋找線(xian)(xian)(xian)纜(lan)，所以它不需打(da)開(kai)線(xian)(xian)(xian)纜(lan)的(de)絕(jue)緣層，在線(xian)(xian)(xian)纜(lan)外皮上的(de)不同部位找到信號。我們可以利用這(zhe)一原(yuan)理在線(xian)(xian)(xian)纜(lan)群束中、地毯下、裝飾(shi)墻內、天花板上迅速找到所需電纜(lan)以及它的(de)斷點的(de)大概(gai)位置。
