一、尋線儀是什么

尋線儀是一種電工工具(ju)，主要用于準(zhun)確地定位地下的電纜、電線等物體的位置。設備由主測(ce)試器，接收器兩(liang)部分組成。具(ju)有尋線、對線及線路(lu)狀態測(ce)試三大功能，具(ju)有快捷、準(zhun)確的特(te)點，是通信線路(lu)，綜(zong)合布線，線路(lu)等弱電系統安裝、維護工程技(ji)術人(ren)員的實用工具(ju)。

也(ye)廣泛(fan)應(ying)用(yong)于電話(hua)系統、計算機網絡及其它(ta)涉及金屬導線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)路等領域。能(neng)夠通過(guo)檢測(ce)地下(xia)線(xian)(xian)(xian)(xian)(xian)路產生的(de)(de)(de)磁場變化(hua)來確定線(xian)(xian)(xian)(xian)(xian)路的(de)(de)(de)位置。尋(xun)線(xian)(xian)(xian)(xian)(xian)儀(yi)可以(yi)將隱藏在地下(xia)的(de)(de)(de)電纜和管(guan)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)位置信(xin)息轉化(hua)成具(ju)體的(de)(de)(de)數(shu)字信(xin)號，并可能(neng)通過(guo)音、光等形式(shi)展現出來，從而實現檢測(ce)和定位的(de)(de)(de)目的(de)(de)(de)。此外，尋(xun)線(xian)(xian)(xian)(xian)(xian)儀(yi)也(ye)可以(yi)用(yong)來尋(xun)找埋在地面以(yi)下(xia)的(de)(de)(de)電力線(xian)(xian)(xian)(xian)(xian)、通信(xin)線(xian)(xian)(xian)(xian)(xian)等線(xian)(xian)(xian)(xian)(xian)路，因(yin)此也(ye)被稱為(wei)地下(xia)線(xian)(xian)(xian)(xian)(xian)路探測(ce)儀(yi)或(huo)地下(xia)線(xian)(xian)(xian)(xian)(xian)路探測(ce)器。在實際應(ying)用(yong)中，尋(xun)線(xian)(xian)(xian)(xian)(xian)儀(yi)可以(yi)幫助電工、工程師或(huo)其他相關人員在需(xu)要布(bu)線(xian)(xian)(xian)(xian)(xian)和維修時更快更精確地找到所需(xu)線(xian)(xian)(xian)(xian)(xian)路，對(dui)于網絡線(xian)(xian)(xian)(xian)(xian)纜、通訊線(xian)(xian)(xian)(xian)(xian)纜、各(ge)種(zhong)金屬線(xian)(xian)(xian)(xian)(xian)路施(shi)工工程和日常維護過(guo)程中的(de)(de)(de)查(cha)找線(xian)(xian)(xian)(xian)(xian)纜也(ye)非常有用(yong)。

二、尋線儀的工作原理是什么

尋(xun)(xun)線(xian)(xian)(xian)儀(yi)可以迅(xun)速高效地從大(da)量的(de)(de)(de)(de)線(xian)(xian)(xian)束線(xian)(xian)(xian)纜(lan)(lan)(lan)中(zhong)找到(dao)(dao)所需線(xian)(xian)(xian)纜(lan)(lan)(lan)，是(shi)網絡線(xian)(xian)(xian)纜(lan)(lan)(lan)、通(tong)(tong)訊線(xian)(xian)(xian)纜(lan)(lan)(lan)、各種金屬線(xian)(xian)(xian)路施(shi)工工程和(he)日常維(wei)護過程中(zhong)查找線(xian)(xian)(xian)纜(lan)(lan)(lan)的(de)(de)(de)(de)必備工具，由信(xin)號震蕩(dang)發聲(sheng)(sheng)器和(he)尋(xun)(xun)線(xian)(xian)(xian)器及相應(ying)的(de)(de)(de)(de)適配線(xian)(xian)(xian)組成，其(qi)工作原理(li)是(shi)尋(xun)(xun)信(xin)號震蕩(dang)發聲(sheng)(sheng)器發出的(de)(de)(de)(de)聲(sheng)(sheng)音信(xin)號通(tong)(tong)過RJ45/RJ11通(tong)(tong)用(yong)接口接入(ru)目(mu)標線(xian)(xian)(xian)纜(lan)(lan)(lan)的(de)(de)(de)(de)端(duan)口上，至使目(mu)標線(xian)(xian)(xian)纜(lan)(lan)(lan)回路周圍產生一環繞的(de)(de)(de)(de)聲(sheng)(sheng)音信(xin)號場(chang)，用(yong)高靈敏度(du)感應(ying)式尋(xun)(xun)線(xian)(xian)(xian)儀(yi)很快在回路沿途和(he)未端(duan)識(shi)別它發出的(de)(de)(de)(de)信(xin)號場(chang)，從而找到(dao)(dao)這條目(mu)的(de)(de)(de)(de)線(xian)(xian)(xian)纜(lan)(lan)(lan)。

尋線儀是(shi)利(li)用了感應尋(xun)線(xian)(xian)(xian)原(yuan)理來尋(xun)找(zhao)(zhao)線(xian)(xian)(xian)纜(lan)，所(suo)以它不(bu)需打開線(xian)(xian)(xian)纜(lan)的(de)絕緣層，在線(xian)(xian)(xian)纜(lan)外皮上(shang)的(de)不(bu)同部位找(zhao)(zhao)到(dao)信(xin)號。我們可以利(li)用這(zhe)一(yi)原(yuan)理在線(xian)(xian)(xian)纜(lan)群束中(zhong)、地毯下、裝飾墻內、天(tian)花(hua)板上(shang)迅(xun)速找(zhao)(zhao)到(dao)所(suo)需電纜(lan)以及它的(de)斷點的(de)大概位置。
