一、尋線儀是什么

尋線儀是一種電(dian)工(gong)工(gong)具(ju)，主(zhu)要(yao)用于準確地定位(wei)地下的(de)電(dian)纜、電(dian)線(xian)(xian)(xian)(xian)等物(wu)體的(de)位(wei)置。設備由(you)主(zhu)測試器，接收(shou)器兩部(bu)分組成。具(ju)有尋線(xian)(xian)(xian)(xian)、對(dui)線(xian)(xian)(xian)(xian)及線(xian)(xian)(xian)(xian)路(lu)狀態測試三大功能，具(ju)有快捷、準確的(de)特點(dian)，是通信線(xian)(xian)(xian)(xian)路(lu)，綜合(he)布線(xian)(xian)(xian)(xian)，線(xian)(xian)(xian)(xian)路(lu)等弱(ruo)電(dian)系統(tong)安裝、維護(hu)工(gong)程技術人員的(de)實用工(gong)具(ju)。

也廣泛(fan)應用于(yu)電話(hua)系統、計(ji)算機(ji)網(wang)絡及其它(ta)涉及金屬導線(xian)(xian)(xian)線(xian)(xian)(xian)路等(deng)領(ling)域。能(neng)夠通(tong)(tong)過檢測(ce)(ce)地(di)下線(xian)(xian)(xian)路產生的(de)(de)磁場變化來(lai)確定線(xian)(xian)(xian)路的(de)(de)位置(zhi)。尋線(xian)(xian)(xian)儀(yi)(yi)(yi)可以將隱(yin)藏在(zai)地(di)下的(de)(de)電纜(lan)和管線(xian)(xian)(xian)的(de)(de)位置(zhi)信息轉化成(cheng)具體(ti)的(de)(de)數字信號(hao)，并可能(neng)通(tong)(tong)過音、光等(deng)形式展現出來(lai)，從而實現檢測(ce)(ce)和定位的(de)(de)目的(de)(de)。此(ci)外，尋線(xian)(xian)(xian)儀(yi)(yi)(yi)也可以用來(lai)尋找埋在(zai)地(di)面以下的(de)(de)電力(li)線(xian)(xian)(xian)、通(tong)(tong)信線(xian)(xian)(xian)等(deng)線(xian)(xian)(xian)路，因此(ci)也被稱(cheng)為地(di)下線(xian)(xian)(xian)路探(tan)測(ce)(ce)儀(yi)(yi)(yi)或(huo)(huo)地(di)下線(xian)(xian)(xian)路探(tan)測(ce)(ce)器(qi)。在(zai)實際(ji)應用中(zhong)，尋線(xian)(xian)(xian)儀(yi)(yi)(yi)可以幫助電工(gong)、工(gong)程(cheng)師或(huo)(huo)其他相(xiang)關人員在(zai)需(xu)要布線(xian)(xian)(xian)和維修(xiu)時更快更精確地(di)找到(dao)所需(xu)線(xian)(xian)(xian)路，對于(yu)網(wang)絡線(xian)(xian)(xian)纜(lan)、通(tong)(tong)訊線(xian)(xian)(xian)纜(lan)、各種金屬線(xian)(xian)(xian)路施工(gong)工(gong)程(cheng)和日常維護過程(cheng)中(zhong)的(de)(de)查找線(xian)(xian)(xian)纜(lan)也非常有用。

二、尋線儀的工作原理是什么

尋(xun)線(xian)(xian)(xian)(xian)儀可以(yi)迅速高(gao)效地從(cong)大量的(de)線(xian)(xian)(xian)(xian)束線(xian)(xian)(xian)(xian)纜(lan)中找到(dao)所需線(xian)(xian)(xian)(xian)纜(lan)，是(shi)網絡線(xian)(xian)(xian)(xian)纜(lan)、通(tong)訊線(xian)(xian)(xian)(xian)纜(lan)、各種(zhong)金屬線(xian)(xian)(xian)(xian)路施工工程(cheng)和日常(chang)維護過(guo)程(cheng)中查找線(xian)(xian)(xian)(xian)纜(lan)的(de)必備工具，由信(xin)(xin)號震蕩發(fa)聲(sheng)器(qi)(qi)和尋(xun)線(xian)(xian)(xian)(xian)器(qi)(qi)及相應的(de)適(shi)配線(xian)(xian)(xian)(xian)組成，其(qi)工作原理(li)是(shi)尋(xun)信(xin)(xin)號震蕩發(fa)聲(sheng)器(qi)(qi)發(fa)出(chu)(chu)的(de)聲(sheng)音信(xin)(xin)號通(tong)過(guo)RJ45/RJ11通(tong)用(yong)接口(kou)接入目標線(xian)(xian)(xian)(xian)纜(lan)的(de)端口(kou)上，至使目標線(xian)(xian)(xian)(xian)纜(lan)回(hui)路周圍產生一環(huan)繞的(de)聲(sheng)音信(xin)(xin)號場，用(yong)高(gao)靈敏度感應式(shi)尋(xun)線(xian)(xian)(xian)(xian)儀很快在回(hui)路沿途和未端識別它發(fa)出(chu)(chu)的(de)信(xin)(xin)號場，從(cong)而找到(dao)這(zhe)條目的(de)線(xian)(xian)(xian)(xian)纜(lan)。

尋線儀是利(li)用了感應尋(xun)線(xian)原理(li)(li)來尋(xun)找(zhao)線(xian)纜(lan)，所(suo)以它不(bu)需(xu)(xu)打(da)開線(xian)纜(lan)的(de)絕緣層，在線(xian)纜(lan)外皮上的(de)不(bu)同部位找(zhao)到(dao)信(xin)號。我們可以利(li)用這(zhe)一(yi)原理(li)(li)在線(xian)纜(lan)群(qun)束(shu)中、地毯下、裝飾(shi)墻內、天花板上迅(xun)速找(zhao)到(dao)所(suo)需(xu)(xu)電(dian)纜(lan)以及(ji)它的(de)斷(duan)點的(de)大概位置。
