二、尋線儀的工作原理是什么

尋(xun)線(xian)(xian)(xian)儀(yi)可以迅(xun)速高效地從大量的(de)(de)線(xian)(xian)(xian)束(shu)線(xian)(xian)(xian)纜(lan)(lan)(lan)(lan)中找到所(suo)需線(xian)(xian)(xian)纜(lan)(lan)(lan)(lan)，是(shi)網(wang)絡線(xian)(xian)(xian)纜(lan)(lan)(lan)(lan)、通(tong)訊(xun)線(xian)(xian)(xian)纜(lan)(lan)(lan)(lan)、各種金屬線(xian)(xian)(xian)路(lu)施工工程(cheng)和日(ri)常維護過(guo)程(cheng)中查找線(xian)(xian)(xian)纜(lan)(lan)(lan)(lan)的(de)(de)必備工具(ju)，由(you)信(xin)(xin)(xin)號(hao)震蕩發聲器(qi)和尋(xun)線(xian)(xian)(xian)器(qi)及相應的(de)(de)適(shi)配線(xian)(xian)(xian)組成，其工作原理(li)是(shi)尋(xun)信(xin)(xin)(xin)號(hao)震蕩發聲器(qi)發出(chu)的(de)(de)聲音信(xin)(xin)(xin)號(hao)通(tong)過(guo)RJ45/RJ11通(tong)用接口(kou)接入目(mu)標(biao)線(xian)(xian)(xian)纜(lan)(lan)(lan)(lan)的(de)(de)端(duan)口(kou)上，至使目(mu)標(biao)線(xian)(xian)(xian)纜(lan)(lan)(lan)(lan)回(hui)路(lu)周圍產(chan)生一環繞的(de)(de)聲音信(xin)(xin)(xin)號(hao)場，用高靈敏(min)度感應式尋(xun)線(xian)(xian)(xian)儀(yi)很快在回(hui)路(lu)沿(yan)途和未(wei)端(duan)識(shi)別它發出(chu)的(de)(de)信(xin)(xin)(xin)號(hao)場，從而找到這條目(mu)的(de)(de)線(xian)(xian)(xian)纜(lan)(lan)(lan)(lan)。

尋線儀是(shi)利(li)用了感應尋線(xian)(xian)原理來尋找(zhao)線(xian)(xian)纜(lan)(lan)，所以它不需打開線(xian)(xian)纜(lan)(lan)的(de)絕緣層，在(zai)線(xian)(xian)纜(lan)(lan)外皮(pi)上的(de)不同部位找(zhao)到(dao)信號(hao)。我們可以利(li)用這一原理在(zai)線(xian)(xian)纜(lan)(lan)群束中(zhong)、地毯下、裝飾墻內(nei)、天花板上迅速找(zhao)到(dao)所需電纜(lan)(lan)以及它的(de)斷點的(de)大概位置。
