一、尋線儀是什么

尋線儀是一(yi)種電(dian)工工具，主要用(yong)于準確(que)(que)地定位(wei)地下(xia)的(de)電(dian)纜(lan)、電(dian)線(xian)(xian)等(deng)物體的(de)位(wei)置。設備由主測試(shi)器，接收器兩部分組成。具有(you)尋線(xian)(xian)、對(dui)線(xian)(xian)及(ji)線(xian)(xian)路狀態測試(shi)三大功能，具有(you)快捷、準確(que)(que)的(de)特點(dian)，是通信線(xian)(xian)路，綜(zong)合(he)布線(xian)(xian)，線(xian)(xian)路等(deng)弱電(dian)系統安(an)裝、維護工程技術人(ren)員(yuan)的(de)實用(yong)工具。

也廣泛應用于電話系統、計算機網絡及其(qi)它涉及金屬導線(xian)(xian)(xian)線(xian)(xian)(xian)路(lu)(lu)(lu)等領域。能夠通過檢測(ce)地(di)下線(xian)(xian)(xian)路(lu)(lu)(lu)產生的(de)磁場(chang)變化來(lai)(lai)確定線(xian)(xian)(xian)路(lu)(lu)(lu)的(de)位(wei)置(zhi)。尋(xun)線(xian)(xian)(xian)儀可以(yi)將隱藏在(zai)(zai)地(di)下的(de)電纜(lan)和(he)管線(xian)(xian)(xian)的(de)位(wei)置(zhi)信(xin)息轉(zhuan)化成具體的(de)數字信(xin)號，并(bing)可能通過音、光(guang)等形式(shi)展現(xian)出(chu)來(lai)(lai)，從而(er)實現(xian)檢測(ce)和(he)定位(wei)的(de)目的(de)。此外，尋(xun)線(xian)(xian)(xian)儀也可以(yi)用來(lai)(lai)尋(xun)找埋在(zai)(zai)地(di)面以(yi)下的(de)電力線(xian)(xian)(xian)、通信(xin)線(xian)(xian)(xian)等線(xian)(xian)(xian)路(lu)(lu)(lu)，因(yin)此也被稱為地(di)下線(xian)(xian)(xian)路(lu)(lu)(lu)探測(ce)儀或(huo)地(di)下線(xian)(xian)(xian)路(lu)(lu)(lu)探測(ce)器。在(zai)(zai)實際(ji)應用中(zhong)，尋(xun)線(xian)(xian)(xian)儀可以(yi)幫助電工(gong)、工(gong)程師(shi)或(huo)其(qi)他相關(guan)人員在(zai)(zai)需要布線(xian)(xian)(xian)和(he)維修時更快(kuai)更精確地(di)找到所需線(xian)(xian)(xian)路(lu)(lu)(lu)，對于網絡線(xian)(xian)(xian)纜(lan)、通訊線(xian)(xian)(xian)纜(lan)、各種金屬線(xian)(xian)(xian)路(lu)(lu)(lu)施工(gong)工(gong)程和(he)日(ri)常維護過程中(zhong)的(de)查找線(xian)(xian)(xian)纜(lan)也非(fei)常有用。

二、尋線儀的工作原理是什么

尋線(xian)(xian)(xian)(xian)儀可以迅速高(gao)效地從大量的(de)(de)線(xian)(xian)(xian)(xian)束線(xian)(xian)(xian)(xian)纜(lan)中找(zhao)到(dao)所需線(xian)(xian)(xian)(xian)纜(lan)，是網絡線(xian)(xian)(xian)(xian)纜(lan)、通訊線(xian)(xian)(xian)(xian)纜(lan)、各種金屬線(xian)(xian)(xian)(xian)路(lu)施(shi)工(gong)(gong)工(gong)(gong)程和(he)日常維(wei)護過程中查找(zhao)線(xian)(xian)(xian)(xian)纜(lan)的(de)(de)必備工(gong)(gong)具(ju)，由(you)信(xin)(xin)(xin)號(hao)(hao)震蕩(dang)發(fa)(fa)聲器(qi)和(he)尋線(xian)(xian)(xian)(xian)器(qi)及相應的(de)(de)適配(pei)線(xian)(xian)(xian)(xian)組成，其(qi)工(gong)(gong)作原理(li)是尋信(xin)(xin)(xin)號(hao)(hao)震蕩(dang)發(fa)(fa)聲器(qi)發(fa)(fa)出(chu)的(de)(de)聲音信(xin)(xin)(xin)號(hao)(hao)通過RJ45/RJ11通用接(jie)口接(jie)入目標線(xian)(xian)(xian)(xian)纜(lan)的(de)(de)端口上，至使目標線(xian)(xian)(xian)(xian)纜(lan)回路(lu)周圍產生一環繞的(de)(de)聲音信(xin)(xin)(xin)號(hao)(hao)場，用高(gao)靈敏(min)度感應式(shi)尋線(xian)(xian)(xian)(xian)儀很(hen)快在(zai)回路(lu)沿途(tu)和(he)未端識別它發(fa)(fa)出(chu)的(de)(de)信(xin)(xin)(xin)號(hao)(hao)場，從而(er)找(zhao)到(dao)這條(tiao)目的(de)(de)線(xian)(xian)(xian)(xian)纜(lan)。

尋線儀是利(li)用(yong)(yong)了感應尋線(xian)原(yuan)理來尋找線(xian)纜(lan)，所(suo)以(yi)它不(bu)需打開線(xian)纜(lan)的絕(jue)緣層，在線(xian)纜(lan)外皮(pi)上(shang)的不(bu)同部位找到信號。我(wo)們可以(yi)利(li)用(yong)(yong)這一原(yuan)理在線(xian)纜(lan)群束(shu)中(zhong)、地毯下、裝飾墻(qiang)內、天花(hua)板上(shang)迅(xun)速(su)找到所(suo)需電纜(lan)以(yi)及它的斷點(dian)的大概位置。
