一、尋線儀是什么

尋線儀是一種電(dian)(dian)工工具(ju)，主要用(yong)于(yu)準確地定位地下(xia)的(de)電(dian)(dian)纜(lan)、電(dian)(dian)線等(deng)物體的(de)位置。設(she)備由主測試(shi)器，接收器兩部分組成(cheng)。具(ju)有尋(xun)線、對線及線路(lu)狀態(tai)測試(shi)三大功能，具(ju)有快捷、準確的(de)特點，是通(tong)信線路(lu)，綜合布線，線路(lu)等(deng)弱(ruo)電(dian)(dian)系統(tong)安裝(zhuang)、維護(hu)工程技術人員的(de)實用(yong)工具(ju)。

也(ye)(ye)廣泛應(ying)(ying)用(yong)于電(dian)話(hua)系統、計(ji)算機網(wang)絡及(ji)其它涉及(ji)金屬導線(xian)(xian)(xian)線(xian)(xian)(xian)路(lu)(lu)(lu)等(deng)領(ling)域。能(neng)夠通過(guo)檢測(ce)地(di)(di)(di)下(xia)線(xian)(xian)(xian)路(lu)(lu)(lu)產生(sheng)的(de)磁場變化(hua)來確定線(xian)(xian)(xian)路(lu)(lu)(lu)的(de)位(wei)置。尋(xun)線(xian)(xian)(xian)儀(yi)可(ke)以(yi)將隱藏(zang)在地(di)(di)(di)下(xia)的(de)電(dian)纜和(he)管線(xian)(xian)(xian)的(de)位(wei)置信(xin)息轉化(hua)成具體(ti)的(de)數字信(xin)號，并(bing)可(ke)能(neng)通過(guo)音、光等(deng)形式展(zhan)現出來，從而實(shi)現檢測(ce)和(he)定位(wei)的(de)目的(de)。此(ci)外，尋(xun)線(xian)(xian)(xian)儀(yi)也(ye)(ye)可(ke)以(yi)用(yong)來尋(xun)找埋在地(di)(di)(di)面以(yi)下(xia)的(de)電(dian)力線(xian)(xian)(xian)、通信(xin)線(xian)(xian)(xian)等(deng)線(xian)(xian)(xian)路(lu)(lu)(lu)，因此(ci)也(ye)(ye)被稱為地(di)(di)(di)下(xia)線(xian)(xian)(xian)路(lu)(lu)(lu)探測(ce)儀(yi)或地(di)(di)(di)下(xia)線(xian)(xian)(xian)路(lu)(lu)(lu)探測(ce)器。在實(shi)際應(ying)(ying)用(yong)中，尋(xun)線(xian)(xian)(xian)儀(yi)可(ke)以(yi)幫助電(dian)工、工程(cheng)師(shi)或其他相關人員在需(xu)要(yao)布線(xian)(xian)(xian)和(he)維(wei)修時更快(kuai)更精確地(di)(di)(di)找到所需(xu)線(xian)(xian)(xian)路(lu)(lu)(lu)，對于網(wang)絡線(xian)(xian)(xian)纜、通訊(xun)線(xian)(xian)(xian)纜、各種(zhong)金屬線(xian)(xian)(xian)路(lu)(lu)(lu)施工工程(cheng)和(he)日常維(wei)護過(guo)程(cheng)中的(de)查找線(xian)(xian)(xian)纜也(ye)(ye)非(fei)常有用(yong)。

二、尋線儀的工作原理是什么

尋(xun)線(xian)(xian)(xian)(xian)(xian)儀可以迅速高效地(di)從大量(liang)的(de)線(xian)(xian)(xian)(xian)(xian)束線(xian)(xian)(xian)(xian)(xian)纜中(zhong)找(zhao)到所需線(xian)(xian)(xian)(xian)(xian)纜，是(shi)網絡線(xian)(xian)(xian)(xian)(xian)纜、通訊線(xian)(xian)(xian)(xian)(xian)纜、各(ge)種金(jin)屬(shu)線(xian)(xian)(xian)(xian)(xian)路施(shi)工工程和日常(chang)維護(hu)過程中(zhong)查找(zhao)線(xian)(xian)(xian)(xian)(xian)纜的(de)必備工具，由(you)信(xin)號震(zhen)(zhen)蕩發(fa)聲(sheng)器和尋(xun)線(xian)(xian)(xian)(xian)(xian)器及相(xiang)應的(de)適(shi)配線(xian)(xian)(xian)(xian)(xian)組(zu)成，其工作(zuo)原理是(shi)尋(xun)信(xin)號震(zhen)(zhen)蕩發(fa)聲(sheng)器發(fa)出(chu)的(de)聲(sheng)音(yin)信(xin)號通過RJ45/RJ11通用(yong)接口(kou)接入目(mu)(mu)標(biao)線(xian)(xian)(xian)(xian)(xian)纜的(de)端口(kou)上，至(zhi)使目(mu)(mu)標(biao)線(xian)(xian)(xian)(xian)(xian)纜回路周圍產生(sheng)一環繞的(de)聲(sheng)音(yin)信(xin)號場(chang)，用(yong)高靈敏度感應式尋(xun)線(xian)(xian)(xian)(xian)(xian)儀很快在(zai)回路沿途(tu)和未端識別它發(fa)出(chu)的(de)信(xin)號場(chang)，從而找(zhao)到這條目(mu)(mu)的(de)線(xian)(xian)(xian)(xian)(xian)纜。

尋線儀是(shi)利(li)用了(le)感應(ying)尋線(xian)(xian)(xian)原(yuan)(yuan)理來尋找(zhao)線(xian)(xian)(xian)纜(lan)，所(suo)以它(ta)(ta)不(bu)需(xu)打(da)開線(xian)(xian)(xian)纜(lan)的絕緣層，在(zai)線(xian)(xian)(xian)纜(lan)外皮上的不(bu)同部(bu)位(wei)找(zhao)到信(xin)號。我們可(ke)以利(li)用這(zhe)一原(yuan)(yuan)理在(zai)線(xian)(xian)(xian)纜(lan)群束中、地毯下、裝飾墻內(nei)、天花板上迅速找(zhao)到所(suo)需(xu)電纜(lan)以及它(ta)(ta)的斷點的大概位(wei)置。
