一、尋線儀是什么

尋線儀是一種電(dian)(dian)工工具(ju)，主要用于準確地(di)定位(wei)地(di)下的(de)電(dian)(dian)纜、電(dian)(dian)線等物體的(de)位(wei)置。設備(bei)由主測(ce)試器，接收器兩部分組成(cheng)。具(ju)有(you)尋線、對線及線路狀(zhuang)態測(ce)試三大功能，具(ju)有(you)快(kuai)捷、準確的(de)特點，是通信線路，綜合(he)布線，線路等弱(ruo)電(dian)(dian)系(xi)統安(an)裝、維護工程技術人員(yuan)的(de)實用工具(ju)。

也廣(guang)泛(fan)應用(yong)于電(dian)話系統、計算機網絡(luo)及其(qi)它涉(she)及金屬導線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)路(lu)等領域。能夠通過檢測地(di)下(xia)(xia)線(xian)(xian)(xian)(xian)路(lu)產生的(de)(de)磁場變化來確(que)定(ding)線(xian)(xian)(xian)(xian)路(lu)的(de)(de)位(wei)置。尋線(xian)(xian)(xian)(xian)儀(yi)可以(yi)將(jiang)隱藏在(zai)地(di)下(xia)(xia)的(de)(de)電(dian)纜(lan)(lan)和(he)管線(xian)(xian)(xian)(xian)的(de)(de)位(wei)置信息轉化成具體的(de)(de)數字信號(hao)，并(bing)可能通過音(yin)、光等形式展現出(chu)來，從而實現檢測和(he)定(ding)位(wei)的(de)(de)目的(de)(de)。此外，尋線(xian)(xian)(xian)(xian)儀(yi)也可以(yi)用(yong)來尋找埋在(zai)地(di)面以(yi)下(xia)(xia)的(de)(de)電(dian)力(li)線(xian)(xian)(xian)(xian)、通信線(xian)(xian)(xian)(xian)等線(xian)(xian)(xian)(xian)路(lu)，因此也被(bei)稱(cheng)為(wei)地(di)下(xia)(xia)線(xian)(xian)(xian)(xian)路(lu)探測儀(yi)或地(di)下(xia)(xia)線(xian)(xian)(xian)(xian)路(lu)探測器。在(zai)實際(ji)應用(yong)中，尋線(xian)(xian)(xian)(xian)儀(yi)可以(yi)幫助電(dian)工、工程(cheng)師或其(qi)他相關人員(yuan)在(zai)需要布(bu)線(xian)(xian)(xian)(xian)和(he)維修時(shi)更快更精確(que)地(di)找到所(suo)需線(xian)(xian)(xian)(xian)路(lu)，對(dui)于網絡(luo)線(xian)(xian)(xian)(xian)纜(lan)(lan)、通訊線(xian)(xian)(xian)(xian)纜(lan)(lan)、各種金屬線(xian)(xian)(xian)(xian)路(lu)施工工程(cheng)和(he)日常(chang)維護過程(cheng)中的(de)(de)查(cha)找線(xian)(xian)(xian)(xian)纜(lan)(lan)也非常(chang)有(you)用(yong)。

二、尋線儀的工作原理是什么

尋線(xian)(xian)(xian)儀可以迅速高(gao)效地從(cong)大(da)量的線(xian)(xian)(xian)束(shu)線(xian)(xian)(xian)纜中找(zhao)到(dao)所需線(xian)(xian)(xian)纜，是網絡線(xian)(xian)(xian)纜、通訊線(xian)(xian)(xian)纜、各種(zhong)金屬(shu)線(xian)(xian)(xian)路施工工程和日常維護(hu)過程中查找(zhao)線(xian)(xian)(xian)纜的必備(bei)工具(ju)，由信(xin)(xin)號(hao)震(zhen)蕩(dang)發聲(sheng)器和尋線(xian)(xian)(xian)器及相應(ying)的適配線(xian)(xian)(xian)組成，其工作原理是尋信(xin)(xin)號(hao)震(zhen)蕩(dang)發聲(sheng)器發出的聲(sheng)音(yin)信(xin)(xin)號(hao)通過RJ45/RJ11通用接口(kou)接入(ru)目標線(xian)(xian)(xian)纜的端(duan)口(kou)上，至使目標線(xian)(xian)(xian)纜回(hui)路周圍(wei)產生(sheng)一環繞的聲(sheng)音(yin)信(xin)(xin)號(hao)場(chang)，用高(gao)靈(ling)敏(min)度感應(ying)式尋線(xian)(xian)(xian)儀很快在(zai)回(hui)路沿途(tu)和未(wei)端(duan)識別它發出的信(xin)(xin)號(hao)場(chang)，從(cong)而找(zhao)到(dao)這條目的線(xian)(xian)(xian)纜。

尋線儀是(shi)利(li)用了感應尋線原(yuan)理來尋找(zhao)(zhao)線纜(lan)(lan)，所以它不需打開線纜(lan)(lan)的絕緣層，在線纜(lan)(lan)外皮上(shang)的不同部位(wei)找(zhao)(zhao)到信號(hao)。我們可以利(li)用這一原(yuan)理在線纜(lan)(lan)群束中、地毯下(xia)、裝飾(shi)墻內(nei)、天花板上(shang)迅速找(zhao)(zhao)到所需電纜(lan)(lan)以及它的斷點的大概位(wei)置。
