一、尋線儀是什么
尋線儀是(shi)一種電工(gong)工(gong)具,主(zhu)要用于準(zhun)確地定(ding)位地下的(de)電纜、電線等物體的(de)位置。設備(bei)由(you)主(zhu)測(ce)(ce)試(shi)器,接收器兩部分組成。具有尋線、對(dui)線及線路(lu)狀態測(ce)(ce)試(shi)三大(da)功(gong)能,具有快(kuai)捷、準(zhun)確的(de)特(te)點,是(shi)通信線路(lu),綜(zong)合布線,線路(lu)等弱電系統(tong)安(an)裝、維護工(gong)程技術人員的(de)實用工(gong)具。
也(ye)(ye)廣(guang)泛應(ying)用(yong)于(yu)(yu)電(dian)話系統、計(ji)算機網絡及(ji)其它(ta)涉(she)及(ji)金屬導線(xian)(xian)(xian)線(xian)(xian)(xian)路(lu)(lu)(lu)(lu)等領域。能夠(gou)通過(guo)(guo)檢(jian)測地(di)下(xia)線(xian)(xian)(xian)路(lu)(lu)(lu)(lu)產(chan)生的(de)(de)磁場變化(hua)來確定(ding)線(xian)(xian)(xian)路(lu)(lu)(lu)(lu)的(de)(de)位置(zhi)。尋(xun)線(xian)(xian)(xian)儀(yi)可(ke)以(yi)將隱藏(zang)在(zai)地(di)下(xia)的(de)(de)電(dian)纜(lan)(lan)和(he)管線(xian)(xian)(xian)的(de)(de)位置(zhi)信息轉化(hua)成具體的(de)(de)數字(zi)信號,并可(ke)能通過(guo)(guo)音、光等形(xing)式展現出來,從而實(shi)現檢(jian)測和(he)定(ding)位的(de)(de)目的(de)(de)。此(ci)(ci)外,尋(xun)線(xian)(xian)(xian)儀(yi)也(ye)(ye)可(ke)以(yi)用(yong)來尋(xun)找(zhao)(zhao)埋在(zai)地(di)面以(yi)下(xia)的(de)(de)電(dian)力(li)線(xian)(xian)(xian)、通信線(xian)(xian)(xian)等線(xian)(xian)(xian)路(lu)(lu)(lu)(lu),因此(ci)(ci)也(ye)(ye)被稱為地(di)下(xia)線(xian)(xian)(xian)路(lu)(lu)(lu)(lu)探測儀(yi)或(huo)地(di)下(xia)線(xian)(xian)(xian)路(lu)(lu)(lu)(lu)探測器。在(zai)實(shi)際應(ying)用(yong)中(zhong),尋(xun)線(xian)(xian)(xian)儀(yi)可(ke)以(yi)幫助電(dian)工(gong)、工(gong)程師或(huo)其他相關人員在(zai)需(xu)要布線(xian)(xian)(xian)和(he)維修時更快更精確地(di)找(zhao)(zhao)到所需(xu)線(xian)(xian)(xian)路(lu)(lu)(lu)(lu),對于(yu)(yu)網絡線(xian)(xian)(xian)纜(lan)(lan)、通訊(xun)線(xian)(xian)(xian)纜(lan)(lan)、各種金屬線(xian)(xian)(xian)路(lu)(lu)(lu)(lu)施工(gong)工(gong)程和(he)日常(chang)維護過(guo)(guo)程中(zhong)的(de)(de)查找(zhao)(zhao)線(xian)(xian)(xian)纜(lan)(lan)也(ye)(ye)非常(chang)有用(yong)。
二、尋線儀的工作原理是什么
尋(xun)線(xian)(xian)(xian)儀可(ke)以迅速高效地從大量(liang)的(de)(de)線(xian)(xian)(xian)束線(xian)(xian)(xian)纜(lan)(lan)(lan)中找(zhao)(zhao)到所需線(xian)(xian)(xian)纜(lan)(lan)(lan),是網絡線(xian)(xian)(xian)纜(lan)(lan)(lan)、通(tong)訊線(xian)(xian)(xian)纜(lan)(lan)(lan)、各種(zhong)金屬線(xian)(xian)(xian)路(lu)施工工程和日常維護過程中查找(zhao)(zhao)線(xian)(xian)(xian)纜(lan)(lan)(lan)的(de)(de)必(bi)備工具,由信(xin)號(hao)震蕩(dang)發聲(sheng)器和尋(xun)線(xian)(xian)(xian)器及相應(ying)的(de)(de)適配線(xian)(xian)(xian)組(zu)成,其工作原理是尋(xun)信(xin)號(hao)震蕩(dang)發聲(sheng)器發出(chu)的(de)(de)聲(sheng)音(yin)信(xin)號(hao)通(tong)過RJ45/RJ11通(tong)用(yong)接(jie)口接(jie)入目標線(xian)(xian)(xian)纜(lan)(lan)(lan)的(de)(de)端口上,至使目標線(xian)(xian)(xian)纜(lan)(lan)(lan)回路(lu)周圍(wei)產生一環(huan)繞的(de)(de)聲(sheng)音(yin)信(xin)號(hao)場(chang),用(yong)高靈敏度感應(ying)式尋(xun)線(xian)(xian)(xian)儀很快在(zai)回路(lu)沿途和未端識別(bie)它發出(chu)的(de)(de)信(xin)號(hao)場(chang),從而找(zhao)(zhao)到這(zhe)條目的(de)(de)線(xian)(xian)(xian)纜(lan)(lan)(lan)。
尋線儀是利用了感應(ying)尋線原理(li)來尋找線纜(lan)(lan),所(suo)(suo)以它不需打開線纜(lan)(lan)的(de)絕緣層(ceng),在(zai)線纜(lan)(lan)外皮(pi)上的(de)不同(tong)部位找到信號。我們可以利用這(zhe)一原理(li)在(zai)線纜(lan)(lan)群束中、地毯下、裝飾墻內(nei)、天花板上迅速找到所(suo)(suo)需電纜(lan)(lan)以及它的(de)斷點(dian)的(de)大概位置(zhi)。
