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(zhun)確(que)地定位(wei)(wei)地下的(de)電(dian)(dian)纜、電(dian)(dian)線等(deng)物體(ti)的(de)位(wei)(wei)置。設備由主測試(shi)器(qi)，接收(shou)器(qi)兩部分組成。具(ju)有尋線、對(dui)線及線路(lu)(lu)(lu)狀態測試(shi)三大功能(neng)，具(ju)有快捷(jie)、準(zhun)確(que)的(de)特(te)點，是通(tong)信線路(lu)(lu)(lu)，綜(zong)合布線，線路(lu)(lu)(lu)等(deng)弱(ruo)電(dian)(dian)系統安裝、維護工程技術人員的(de)實用工具(ju)。

也(ye)(ye)廣泛應(ying)用于電(dian)話系統、計(ji)算(suan)機網絡(luo)及(ji)其(qi)它涉及(ji)金屬(shu)導線(xian)(xian)線(xian)(xian)路等(deng)領(ling)域。能夠通(tong)過(guo)檢測(ce)(ce)地(di)下(xia)線(xian)(xian)路產(chan)生的(de)(de)磁場變化來(lai)(lai)確定線(xian)(xian)路的(de)(de)位置。尋線(xian)(xian)儀可(ke)以(yi)(yi)將隱藏在(zai)地(di)下(xia)的(de)(de)電(dian)纜(lan)(lan)和管(guan)線(xian)(xian)的(de)(de)位置信息轉(zhuan)化成具體的(de)(de)數字信號，并可(ke)能通(tong)過(guo)音、光等(deng)形式(shi)展現出來(lai)(lai)，從而實(shi)現檢測(ce)(ce)和定位的(de)(de)目的(de)(de)。此外，尋線(xian)(xian)儀也(ye)(ye)可(ke)以(yi)(yi)用來(lai)(lai)尋找(zhao)埋在(zai)地(di)面以(yi)(yi)下(xia)的(de)(de)電(dian)力線(xian)(xian)、通(tong)信線(xian)(xian)等(deng)線(xian)(xian)路，因此也(ye)(ye)被稱為地(di)下(xia)線(xian)(xian)路探測(ce)(ce)儀或(huo)地(di)下(xia)線(xian)(xian)路探測(ce)(ce)器。在(zai)實(shi)際應(ying)用中，尋線(xian)(xian)儀可(ke)以(yi)(yi)幫助電(dian)工(gong)(gong)、工(gong)(gong)程師或(huo)其(qi)他相關人員在(zai)需要布線(xian)(xian)和維(wei)修時更快更精確地(di)找(zhao)到(dao)所需線(xian)(xian)路，對于網絡(luo)線(xian)(xian)纜(lan)(lan)、通(tong)訊線(xian)(xian)纜(lan)(lan)、各種金屬(shu)線(xian)(xian)路施(shi)工(gong)(gong)工(gong)(gong)程和日常維(wei)護過(guo)程中的(de)(de)查找(zhao)線(xian)(xian)纜(lan)(lan)也(ye)(ye)非常有用。

二、尋線儀的工作原理是什么

尋線(xian)(xian)(xian)儀可以迅(xun)速高(gao)效地從大量的(de)(de)線(xian)(xian)(xian)束線(xian)(xian)(xian)纜(lan)(lan)中找到所需線(xian)(xian)(xian)纜(lan)(lan)，是(shi)網絡線(xian)(xian)(xian)纜(lan)(lan)、通訊線(xian)(xian)(xian)纜(lan)(lan)、各種金屬線(xian)(xian)(xian)路施(shi)工(gong)(gong)工(gong)(gong)程(cheng)和(he)日常維(wei)護過程(cheng)中查找線(xian)(xian)(xian)纜(lan)(lan)的(de)(de)必(bi)備工(gong)(gong)具，由信號震蕩發(fa)聲(sheng)器和(he)尋線(xian)(xian)(xian)器及相應的(de)(de)適(shi)配線(xian)(xian)(xian)組成(cheng)，其工(gong)(gong)作原(yuan)理是(shi)尋信號震蕩發(fa)聲(sheng)器發(fa)出的(de)(de)聲(sheng)音信號通過RJ45/RJ11通用接口接入目(mu)(mu)標(biao)線(xian)(xian)(xian)纜(lan)(lan)的(de)(de)端(duan)口上，至(zhi)使目(mu)(mu)標(biao)線(xian)(xian)(xian)纜(lan)(lan)回(hui)(hui)路周圍產生一環繞的(de)(de)聲(sheng)音信號場(chang)，用高(gao)靈敏度感應式尋線(xian)(xian)(xian)儀很快在(zai)回(hui)(hui)路沿途和(he)未端(duan)識別(bie)它(ta)發(fa)出的(de)(de)信號場(chang)，從而找到這條目(mu)(mu)的(de)(de)線(xian)(xian)(xian)纜(lan)(lan)。

尋線儀是利用了感應尋線(xian)(xian)(xian)原理(li)來尋找線(xian)(xian)(xian)纜(lan)，所以(yi)它不需打開線(xian)(xian)(xian)纜(lan)的(de)(de)絕緣層，在(zai)線(xian)(xian)(xian)纜(lan)外皮上的(de)(de)不同部位(wei)找到信號。我們可以(yi)利用這一原理(li)在(zai)線(xian)(xian)(xian)纜(lan)群束中(zhong)、地毯下、裝飾(shi)墻(qiang)內、天花板(ban)上迅速找到所需電纜(lan)以(yi)及(ji)它的(de)(de)斷點的(de)(de)大概(gai)位(wei)置。
