一、尋線儀是什么

尋線儀是一種電工(gong)工(gong)具(ju)，主要用(yong)于準確地定位(wei)地下的電纜、電線(xian)等(deng)(deng)物體的位(wei)置。設備由主測試(shi)器，接收(shou)器兩部分組成。具(ju)有尋線(xian)、對線(xian)及線(xian)路狀態測試(shi)三大功能，具(ju)有快捷、準確的特(te)點，是通信(xin)線(xian)路，綜合布線(xian)，線(xian)路等(deng)(deng)弱電系統(tong)安裝、維護工(gong)程技術人員(yuan)的實用(yong)工(gong)具(ju)。

也廣泛應用于(yu)電話系(xi)統、計算機網絡及其它涉(she)及金(jin)屬導線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)路(lu)(lu)等(deng)領域(yu)。能夠通(tong)過(guo)檢測(ce)(ce)地(di)(di)下(xia)線(xian)(xian)(xian)(xian)路(lu)(lu)產生的(de)(de)(de)磁場變化來(lai)確定線(xian)(xian)(xian)(xian)路(lu)(lu)的(de)(de)(de)位置。尋線(xian)(xian)(xian)(xian)儀(yi)可以(yi)將隱藏在地(di)(di)下(xia)的(de)(de)(de)電纜(lan)和(he)(he)管(guan)線(xian)(xian)(xian)(xian)的(de)(de)(de)位置信(xin)息轉化成具體的(de)(de)(de)數字信(xin)號，并可能通(tong)過(guo)音、光等(deng)形式展現出來(lai)，從(cong)而實(shi)現檢測(ce)(ce)和(he)(he)定位的(de)(de)(de)目的(de)(de)(de)。此外，尋線(xian)(xian)(xian)(xian)儀(yi)也可以(yi)用來(lai)尋找(zhao)埋(mai)在地(di)(di)面(mian)以(yi)下(xia)的(de)(de)(de)電力線(xian)(xian)(xian)(xian)、通(tong)信(xin)線(xian)(xian)(xian)(xian)等(deng)線(xian)(xian)(xian)(xian)路(lu)(lu)，因此也被稱為地(di)(di)下(xia)線(xian)(xian)(xian)(xian)路(lu)(lu)探測(ce)(ce)儀(yi)或地(di)(di)下(xia)線(xian)(xian)(xian)(xian)路(lu)(lu)探測(ce)(ce)器。在實(shi)際應用中，尋線(xian)(xian)(xian)(xian)儀(yi)可以(yi)幫(bang)助電工(gong)、工(gong)程師(shi)或其他相關(guan)人員在需要布(bu)線(xian)(xian)(xian)(xian)和(he)(he)維修時(shi)更(geng)快更(geng)精確地(di)(di)找(zhao)到所(suo)需線(xian)(xian)(xian)(xian)路(lu)(lu)，對于(yu)網絡線(xian)(xian)(xian)(xian)纜(lan)、通(tong)訊(xun)線(xian)(xian)(xian)(xian)纜(lan)、各種金(jin)屬線(xian)(xian)(xian)(xian)路(lu)(lu)施工(gong)工(gong)程和(he)(he)日常維護過(guo)程中的(de)(de)(de)查找(zhao)線(xian)(xian)(xian)(xian)纜(lan)也非常有(you)用。

二、尋線儀的工作原理是什么

尋線(xian)(xian)儀可以迅(xun)速高效(xiao)地(di)從大(da)量的(de)線(xian)(xian)束線(xian)(xian)纜(lan)(lan)中找到(dao)所需(xu)線(xian)(xian)纜(lan)(lan)，是網(wang)絡線(xian)(xian)纜(lan)(lan)、通訊線(xian)(xian)纜(lan)(lan)、各(ge)種金屬(shu)線(xian)(xian)路(lu)施工(gong)(gong)(gong)工(gong)(gong)(gong)程和(he)(he)日常維(wei)護過(guo)程中查(cha)找線(xian)(xian)纜(lan)(lan)的(de)必備工(gong)(gong)(gong)具(ju)，由(you)信號震(zhen)蕩發聲器和(he)(he)尋線(xian)(xian)器及相應的(de)適配(pei)線(xian)(xian)組成，其工(gong)(gong)(gong)作(zuo)原理是尋信號震(zhen)蕩發聲器發出(chu)的(de)聲音信號通過(guo)RJ45/RJ11通用接口(kou)接入(ru)目標線(xian)(xian)纜(lan)(lan)的(de)端口(kou)上，至使目標線(xian)(xian)纜(lan)(lan)回路(lu)周圍(wei)產(chan)生一(yi)環繞的(de)聲音信號場，用高靈敏度感應式尋線(xian)(xian)儀很快在回路(lu)沿途和(he)(he)未端識別它發出(chu)的(de)信號場，從而找到(dao)這(zhe)條(tiao)目的(de)線(xian)(xian)纜(lan)(lan)。

尋線儀是利用(yong)了(le)感應(ying)尋線(xian)原理來尋找線(xian)纜(lan)，所(suo)以(yi)(yi)它不需打開線(xian)纜(lan)的(de)(de)絕緣層(ceng)，在線(xian)纜(lan)外(wai)皮上(shang)的(de)(de)不同部位找到(dao)信號。我們可(ke)以(yi)(yi)利用(yong)這(zhe)一原理在線(xian)纜(lan)群束中、地毯下、裝飾(shi)墻內、天(tian)花板上(shang)迅速找到(dao)所(suo)需電(dian)纜(lan)以(yi)(yi)及它的(de)(de)斷點(dian)的(de)(de)大概位置(zhi)。
