一、尋線儀是什么
尋線儀是一種電(dian)(dian)工(gong)工(gong)具(ju)(ju),主(zhu)要用(yong)于(yu)準確(que)地定位地下(xia)的(de)電(dian)(dian)纜、電(dian)(dian)線(xian)(xian)等(deng)物體的(de)位置。設備由主(zhu)測試(shi)器,接收器兩(liang)部分組成。具(ju)(ju)有尋線(xian)(xian)、對(dui)線(xian)(xian)及線(xian)(xian)路狀態測試(shi)三大功能(neng),具(ju)(ju)有快捷、準確(que)的(de)特點,是通信線(xian)(xian)路,綜合布線(xian)(xian),線(xian)(xian)路等(deng)弱電(dian)(dian)系(xi)統安裝、維護工(gong)程技術人員的(de)實用(yong)工(gong)具(ju)(ju)。
也廣泛應用(yong)于電(dian)話系統、計(ji)算機網(wang)(wang)絡(luo)及其(qi)它涉及金(jin)屬導線線路(lu)等領域。能夠通(tong)(tong)過(guo)(guo)檢測(ce)地下(xia)線路(lu)產生的磁場變化(hua)來確定線路(lu)的位置。尋(xun)線儀(yi)可(ke)(ke)以將隱藏在(zai)地下(xia)的電(dian)纜(lan)和(he)管線的位置信息轉化(hua)成具體的數(shu)字信號,并可(ke)(ke)能通(tong)(tong)過(guo)(guo)音、光等形(xing)式展現出來,從而實(shi)(shi)現檢測(ce)和(he)定位的目的。此(ci)外,尋(xun)線儀(yi)也可(ke)(ke)以用(yong)來尋(xun)找埋在(zai)地面以下(xia)的電(dian)力線、通(tong)(tong)信線等線路(lu),因此(ci)也被稱為地下(xia)線路(lu)探(tan)測(ce)儀(yi)或(huo)地下(xia)線路(lu)探(tan)測(ce)器。在(zai)實(shi)(shi)際應用(yong)中(zhong),尋(xun)線儀(yi)可(ke)(ke)以幫(bang)助電(dian)工(gong)、工(gong)程師或(huo)其(qi)他相關人員在(zai)需要布線和(he)維修(xiu)時更快更精確地找到所需線路(lu),對于網(wang)(wang)絡(luo)線纜(lan)、通(tong)(tong)訊(xun)線纜(lan)、各種金(jin)屬線路(lu)施工(gong)工(gong)程和(he)日常維護過(guo)(guo)程中(zhong)的查找線纜(lan)也非常有用(yong)。
二、尋線儀的工作原理是什么
尋線(xian)(xian)(xian)(xian)儀可以迅速(su)高(gao)效地從(cong)大(da)量的(de)線(xian)(xian)(xian)(xian)束線(xian)(xian)(xian)(xian)纜(lan)中找(zhao)到(dao)(dao)所需線(xian)(xian)(xian)(xian)纜(lan),是網絡線(xian)(xian)(xian)(xian)纜(lan)、通訊(xun)線(xian)(xian)(xian)(xian)纜(lan)、各(ge)種金屬線(xian)(xian)(xian)(xian)路(lu)(lu)施工工程和日(ri)常維護過程中查找(zhao)線(xian)(xian)(xian)(xian)纜(lan)的(de)必備工具,由(you)信(xin)(xin)號震蕩(dang)(dang)發聲器和尋線(xian)(xian)(xian)(xian)器及相應的(de)適配線(xian)(xian)(xian)(xian)組成,其工作原(yuan)理是尋信(xin)(xin)號震蕩(dang)(dang)發聲器發出的(de)聲音信(xin)(xin)號通過RJ45/RJ11通用接口接入目標線(xian)(xian)(xian)(xian)纜(lan)的(de)端(duan)(duan)口上,至使(shi)目標線(xian)(xian)(xian)(xian)纜(lan)回路(lu)(lu)周圍(wei)產(chan)生一環繞的(de)聲音信(xin)(xin)號場,用高(gao)靈(ling)敏度感應式尋線(xian)(xian)(xian)(xian)儀很快(kuai)在回路(lu)(lu)沿途和未端(duan)(duan)識別它(ta)發出的(de)信(xin)(xin)號場,從(cong)而找(zhao)到(dao)(dao)這條(tiao)目的(de)線(xian)(xian)(xian)(xian)纜(lan)。
尋線儀是利(li)用了感應尋線(xian)原(yuan)理(li)來尋找線(xian)纜(lan)(lan),所(suo)(suo)以它不(bu)需(xu)打開線(xian)纜(lan)(lan)的(de)(de)絕緣(yuan)層(ceng),在線(xian)纜(lan)(lan)外皮上的(de)(de)不(bu)同部(bu)位找到信號。我們可以利(li)用這(zhe)一原(yuan)理(li)在線(xian)纜(lan)(lan)群束(shu)中、地(di)毯下、裝飾墻內(nei)、天花板上迅速(su)找到所(suo)(suo)需(xu)電(dian)纜(lan)(lan)以及它的(de)(de)斷點的(de)(de)大(da)概(gai)位置。
