一、尋線儀是什么

尋線儀是(shi)一種電工工具，主要(yao)用于準(zhun)(zhun)確地(di)定位地(di)下的電纜、電線(xian)等物體(ti)的位置。設備由主測(ce)試(shi)器，接收(shou)器兩部分組成。具有尋線(xian)、對(dui)線(xian)及線(xian)路(lu)狀(zhuang)態測(ce)試(shi)三大(da)功能，具有快捷、準(zhun)(zhun)確的特點，是(shi)通信線(xian)路(lu)，綜合布線(xian)，線(xian)路(lu)等弱電系統安(an)裝、維(wei)護(hu)工程技(ji)術人員的實用工具。

也廣泛應用于電話(hua)系統(tong)、計算機(ji)網(wang)(wang)絡及其它涉及金屬導線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)路(lu)(lu)等領域。能(neng)夠通(tong)過檢測(ce)(ce)地下(xia)(xia)線(xian)(xian)(xian)(xian)(xian)路(lu)(lu)產生的(de)(de)磁場變(bian)化(hua)來確(que)定(ding)線(xian)(xian)(xian)(xian)(xian)路(lu)(lu)的(de)(de)位(wei)置。尋線(xian)(xian)(xian)(xian)(xian)儀(yi)可以(yi)將(jiang)隱藏在地下(xia)(xia)的(de)(de)電纜(lan)和管線(xian)(xian)(xian)(xian)(xian)的(de)(de)位(wei)置信息轉化(hua)成具(ju)體的(de)(de)數字信號，并可能(neng)通(tong)過音、光(guang)等形式展(zhan)現(xian)出(chu)來，從而實現(xian)檢測(ce)(ce)和定(ding)位(wei)的(de)(de)目(mu)的(de)(de)。此外，尋線(xian)(xian)(xian)(xian)(xian)儀(yi)也可以(yi)用來尋找埋在地面以(yi)下(xia)(xia)的(de)(de)電力(li)線(xian)(xian)(xian)(xian)(xian)、通(tong)信線(xian)(xian)(xian)(xian)(xian)等線(xian)(xian)(xian)(xian)(xian)路(lu)(lu)，因此也被(bei)稱為地下(xia)(xia)線(xian)(xian)(xian)(xian)(xian)路(lu)(lu)探(tan)測(ce)(ce)儀(yi)或地下(xia)(xia)線(xian)(xian)(xian)(xian)(xian)路(lu)(lu)探(tan)測(ce)(ce)器。在實際應用中，尋線(xian)(xian)(xian)(xian)(xian)儀(yi)可以(yi)幫助電工(gong)(gong)、工(gong)(gong)程(cheng)師或其他(ta)相關人員在需(xu)要布(bu)線(xian)(xian)(xian)(xian)(xian)和維修時更(geng)快更(geng)精確(que)地找到所需(xu)線(xian)(xian)(xian)(xian)(xian)路(lu)(lu)，對于網(wang)(wang)絡線(xian)(xian)(xian)(xian)(xian)纜(lan)、通(tong)訊(xun)線(xian)(xian)(xian)(xian)(xian)纜(lan)、各(ge)種金屬線(xian)(xian)(xian)(xian)(xian)路(lu)(lu)施工(gong)(gong)工(gong)(gong)程(cheng)和日常維護過程(cheng)中的(de)(de)查找線(xian)(xian)(xian)(xian)(xian)纜(lan)也非(fei)常有用。

二、尋線儀的工作原理是什么

尋(xun)線(xian)(xian)(xian)(xian)儀(yi)可以迅速高效(xiao)地從(cong)大量的(de)(de)線(xian)(xian)(xian)(xian)束線(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)中找到(dao)所需線(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)，是(shi)網絡線(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)、通(tong)訊(xun)線(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)、各種金屬(shu)線(xian)(xian)(xian)(xian)路施工工程和日常維護過程中查找線(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)的(de)(de)必備工具，由信(xin)(xin)號(hao)(hao)(hao)震蕩發(fa)聲(sheng)器(qi)和尋(xun)線(xian)(xian)(xian)(xian)器(qi)及相應的(de)(de)適配線(xian)(xian)(xian)(xian)組成，其(qi)工作原理是(shi)尋(xun)信(xin)(xin)號(hao)(hao)(hao)震蕩發(fa)聲(sheng)器(qi)發(fa)出的(de)(de)聲(sheng)音(yin)(yin)信(xin)(xin)號(hao)(hao)(hao)通(tong)過RJ45/RJ11通(tong)用接口接入目標線(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)的(de)(de)端(duan)口上，至使目標線(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)回路周圍產生一(yi)環繞的(de)(de)聲(sheng)音(yin)(yin)信(xin)(xin)號(hao)(hao)(hao)場，用高靈敏度(du)感(gan)應式尋(xun)線(xian)(xian)(xian)(xian)儀(yi)很快(kuai)在回路沿途(tu)和未端(duan)識別它(ta)發(fa)出的(de)(de)信(xin)(xin)號(hao)(hao)(hao)場，從(cong)而(er)找到(dao)這條目的(de)(de)線(xian)(xian)(xian)(xian)纜(lan)(lan)(lan)。

尋線儀是(shi)利用了(le)感應尋(xun)(xun)線(xian)原理來(lai)尋(xun)(xun)找(zhao)線(xian)纜(lan)，所以(yi)它(ta)不(bu)需打開線(xian)纜(lan)的(de)絕緣層，在線(xian)纜(lan)外皮上的(de)不(bu)同部位找(zhao)到信號。我(wo)們可(ke)以(yi)利用這一原理在線(xian)纜(lan)群束中、地毯下(xia)、裝飾墻內、天花板上迅速找(zhao)到所需電纜(lan)以(yi)及(ji)它(ta)的(de)斷點的(de)大概位置(zhi)。
