一、尋線儀是什么

尋線儀是(shi)一種電(dian)(dian)工(gong)工(gong)具(ju)，主要(yao)用(yong)于準確(que)地(di)定位地(di)下的(de)(de)電(dian)(dian)纜、電(dian)(dian)線等物體的(de)(de)位置(zhi)。設備(bei)由主測(ce)試(shi)器(qi)(qi)，接收器(qi)(qi)兩部分組成。具(ju)有(you)尋(xun)線、對(dui)線及線路狀態測(ce)試(shi)三大功能，具(ju)有(you)快捷、準確(que)的(de)(de)特(te)點，是(shi)通信線路，綜合布線，線路等弱電(dian)(dian)系統安(an)裝、維護(hu)工(gong)程技術人(ren)員的(de)(de)實用(yong)工(gong)具(ju)。

也廣(guang)泛應(ying)用(yong)于(yu)電話系(xi)統、計算機網絡及其(qi)它涉(she)及金屬(shu)導(dao)線(xian)(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)等(deng)領(ling)域。能夠通過檢測地下線(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)產(chan)生的(de)(de)(de)磁場變化來確定線(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)的(de)(de)(de)位(wei)置(zhi)。尋(xun)線(xian)(xian)(xian)(xian)(xian)(xian)儀(yi)可(ke)(ke)以(yi)(yi)將隱藏在地下的(de)(de)(de)電纜(lan)(lan)和(he)管(guan)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)位(wei)置(zhi)信(xin)息轉化成具體的(de)(de)(de)數字信(xin)號，并可(ke)(ke)能通過音、光(guang)等(deng)形式展(zhan)現出來，從(cong)而實現檢測和(he)定位(wei)的(de)(de)(de)目的(de)(de)(de)。此外，尋(xun)線(xian)(xian)(xian)(xian)(xian)(xian)儀(yi)也可(ke)(ke)以(yi)(yi)用(yong)來尋(xun)找埋在地面以(yi)(yi)下的(de)(de)(de)電力(li)線(xian)(xian)(xian)(xian)(xian)(xian)、通信(xin)線(xian)(xian)(xian)(xian)(xian)(xian)等(deng)線(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)，因此也被稱(cheng)為(wei)地下線(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)探測儀(yi)或地下線(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)探測器(qi)。在實際(ji)應(ying)用(yong)中(zhong)，尋(xun)線(xian)(xian)(xian)(xian)(xian)(xian)儀(yi)可(ke)(ke)以(yi)(yi)幫(bang)助電工(gong)、工(gong)程師或其(qi)他相關人員(yuan)在需要布線(xian)(xian)(xian)(xian)(xian)(xian)和(he)維(wei)修時更(geng)快(kuai)更(geng)精確地找到(dao)所需線(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)，對于(yu)網絡線(xian)(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)、通訊線(xian)(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)、各種金屬(shu)線(xian)(xian)(xian)(xian)(xian)(xian)路(lu)(lu)施工(gong)工(gong)程和(he)日常維(wei)護過程中(zhong)的(de)(de)(de)查找線(xian)(xian)(xian)(xian)(xian)(xian)纜(lan)(lan)也非常有用(yong)。

二、尋線儀的工作原理是什么

尋線(xian)儀可以迅速高效地從大量的(de)(de)(de)線(xian)束線(xian)纜中找到所需線(xian)纜，是網絡(luo)線(xian)纜、通訊線(xian)纜、各種金屬線(xian)路(lu)施(shi)工工程(cheng)和日常維(wei)護過程(cheng)中查找線(xian)纜的(de)(de)(de)必備工具，由信(xin)(xin)號震(zhen)蕩發(fa)聲器和尋線(xian)器及相應的(de)(de)(de)適配線(xian)組成，其工作原理是尋信(xin)(xin)號震(zhen)蕩發(fa)聲器發(fa)出的(de)(de)(de)聲音信(xin)(xin)號通過RJ45/RJ11通用接(jie)(jie)口接(jie)(jie)入目標線(xian)纜的(de)(de)(de)端(duan)口上，至使(shi)目標線(xian)纜回路(lu)周(zhou)圍產生(sheng)一(yi)環繞(rao)的(de)(de)(de)聲音信(xin)(xin)號場，用高靈敏度(du)感應式尋線(xian)儀很快在回路(lu)沿途和未端(duan)識別它(ta)發(fa)出的(de)(de)(de)信(xin)(xin)號場，從而找到這條目的(de)(de)(de)線(xian)纜。

尋線儀是利用了感應尋(xun)線(xian)(xian)原(yuan)理來尋(xun)找(zhao)線(xian)(xian)纜(lan)(lan)(lan)，所(suo)以(yi)它不需打開線(xian)(xian)纜(lan)(lan)(lan)的(de)(de)絕緣層，在(zai)線(xian)(xian)纜(lan)(lan)(lan)外(wai)皮上(shang)的(de)(de)不同部(bu)位(wei)找(zhao)到(dao)信號。我們(men)可以(yi)利用這一原(yuan)理在(zai)線(xian)(xian)纜(lan)(lan)(lan)群(qun)束中、地毯下、裝飾墻內、天花板上(shang)迅速找(zhao)到(dao)所(suo)需電纜(lan)(lan)(lan)以(yi)及(ji)它的(de)(de)斷(duan)點的(de)(de)大概位(wei)置(zhi)。
