一、尋線儀是什么

尋線儀是(shi)一種電工工具(ju)(ju)，主(zhu)要用于準確(que)(que)地(di)定位地(di)下的電纜、電線(xian)(xian)等物體的位置。設(she)備由主(zhu)測試(shi)器，接收器兩部分組成(cheng)。具(ju)(ju)有尋線(xian)(xian)、對線(xian)(xian)及(ji)線(xian)(xian)路(lu)狀態(tai)測試(shi)三大功能，具(ju)(ju)有快(kuai)捷、準確(que)(que)的特(te)點，是(shi)通信線(xian)(xian)路(lu)，綜合布線(xian)(xian)，線(xian)(xian)路(lu)等弱(ruo)電系(xi)統安(an)裝、維護工程(cheng)技術人(ren)員的實(shi)用工具(ju)(ju)。

也(ye)廣(guang)泛應用(yong)于(yu)電(dian)(dian)(dian)話系統、計算(suan)機(ji)網(wang)絡(luo)及其(qi)它(ta)涉(she)及金屬導線(xian)(xian)(xian)線(xian)(xian)(xian)路(lu)(lu)等領域。能夠(gou)通過檢(jian)測地下(xia)線(xian)(xian)(xian)路(lu)(lu)產生(sheng)的(de)(de)磁(ci)場變化(hua)(hua)來確(que)定線(xian)(xian)(xian)路(lu)(lu)的(de)(de)位(wei)置。尋線(xian)(xian)(xian)儀可(ke)以(yi)將隱藏(zang)在地下(xia)的(de)(de)電(dian)(dian)(dian)纜和(he)(he)管線(xian)(xian)(xian)的(de)(de)位(wei)置信(xin)(xin)息轉化(hua)(hua)成(cheng)具體(ti)的(de)(de)數字信(xin)(xin)號(hao)，并可(ke)能通過音、光等形式(shi)展現出來，從而實(shi)現檢(jian)測和(he)(he)定位(wei)的(de)(de)目的(de)(de)。此(ci)外，尋線(xian)(xian)(xian)儀也(ye)可(ke)以(yi)用(yong)來尋找(zhao)埋在地面以(yi)下(xia)的(de)(de)電(dian)(dian)(dian)力線(xian)(xian)(xian)、通信(xin)(xin)線(xian)(xian)(xian)等線(xian)(xian)(xian)路(lu)(lu)，因此(ci)也(ye)被稱為地下(xia)線(xian)(xian)(xian)路(lu)(lu)探測儀或地下(xia)線(xian)(xian)(xian)路(lu)(lu)探測器。在實(shi)際(ji)應用(yong)中，尋線(xian)(xian)(xian)儀可(ke)以(yi)幫助電(dian)(dian)(dian)工(gong)、工(gong)程(cheng)師(shi)或其(qi)他相關(guan)人員(yuan)在需要布線(xian)(xian)(xian)和(he)(he)維(wei)修(xiu)時更(geng)快更(geng)精確(que)地找(zhao)到所需線(xian)(xian)(xian)路(lu)(lu)，對于(yu)網(wang)絡(luo)線(xian)(xian)(xian)纜、通訊(xun)線(xian)(xian)(xian)纜、各種金屬線(xian)(xian)(xian)路(lu)(lu)施工(gong)工(gong)程(cheng)和(he)(he)日常維(wei)護過程(cheng)中的(de)(de)查找(zhao)線(xian)(xian)(xian)纜也(ye)非常有用(yong)。

二、尋線儀的工作原理是什么

尋(xun)線(xian)(xian)(xian)(xian)儀(yi)可以迅速(su)高效地從大量的(de)(de)線(xian)(xian)(xian)(xian)束線(xian)(xian)(xian)(xian)纜(lan)中找到所需線(xian)(xian)(xian)(xian)纜(lan)，是(shi)(shi)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)路施工工程和日常維(wei)護過程中查(cha)找線(xian)(xian)(xian)(xian)纜(lan)的(de)(de)必備(bei)工具(ju)，由信(xin)號(hao)震(zhen)蕩發(fa)(fa)聲(sheng)器和尋(xun)線(xian)(xian)(xian)(xian)器及相應的(de)(de)適配線(xian)(xian)(xian)(xian)組成，其工作原理是(shi)(shi)尋(xun)信(xin)號(hao)震(zhen)蕩發(fa)(fa)聲(sheng)器發(fa)(fa)出(chu)的(de)(de)聲(sheng)音信(xin)號(hao)通過RJ45/RJ11通用接口接入目標(biao)線(xian)(xian)(xian)(xian)纜(lan)的(de)(de)端口上，至使目標(biao)線(xian)(xian)(xian)(xian)纜(lan)回路周圍產生一(yi)環繞的(de)(de)聲(sheng)音信(xin)號(hao)場，用高靈敏度感(gan)應式(shi)尋(xun)線(xian)(xian)(xian)(xian)儀(yi)很(hen)快在回路沿途和未(wei)端識別它發(fa)(fa)出(chu)的(de)(de)信(xin)號(hao)場，從而找到這條目的(de)(de)線(xian)(xian)(xian)(xian)纜(lan)。

尋線儀是利用(yong)(yong)了(le)感應尋線(xian)(xian)(xian)原理(li)(li)來尋找線(xian)(xian)(xian)纜，所以(yi)它不(bu)需打開(kai)線(xian)(xian)(xian)纜的(de)絕緣層(ceng)，在線(xian)(xian)(xian)纜外皮上(shang)的(de)不(bu)同部位(wei)找到信號(hao)。我(wo)們(men)可以(yi)利用(yong)(yong)這一原理(li)(li)在線(xian)(xian)(xian)纜群束中、地(di)毯下、裝飾墻內、天花板上(shang)迅速找到所需電(dian)纜以(yi)及它的(de)斷(duan)點的(de)大概位(wei)置。
