工作原理

發射機和(he)接(jie)收(shou)(shou)(shou)機采用單(dan)片機編(bian)碼(ma)、解碼(ma)技術和(he)廣泛應用在通信(xin)領域里的(de)(de)(de)(de)PSK技術。在發射卡(ka)鉗上(shang)發射平均(jun)值(zhi)為(wei)0 的(de)(de)(de)(de)相(xiang)(xiang)位編(bian)碼(ma)信(xin)號(hao)，接(jie)收(shou)(shou)(shou)機中的(de)(de)(de)(de)單(dan)片機對接(jie)收(shou)(shou)(shou)的(de)(de)(de)(de)信(xin)號(hao)經過硬件和(he)軟(ruan)件的(de)(de)(de)(de)濾(lv)波后，再進行相(xiang)(xiang)位識(shi)(shi)別。將發射卡(ka)鉗和(he)接(jie)收(shou)(shou)(shou)卡(ka)鉗的(de)(de)(de)(de)箭頭指(zhi)向電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)終(zhong)端，當接(jie)收(shou)(shou)(shou)機卡(ka)鉗鉗住某根電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)，接(jie)收(shou)(shou)(shou)機電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流表(biao)右偏(pian)，同(tong)時伴有聲光指(zhi)示(shi)。而鉗住其它的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流表(biao)左(zuo)偏(pian)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流方向與被(bei)識(shi)(shi)別電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流方向相(xiang)(xiang)反，沒(mei)有聲光指(zhi)示(shi)。這就體(ti)現了被(bei)識(shi)(shi)別的(de)(de)(de)(de)目標電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)(de)*性。很容易將被(bei)識(shi)(shi)別電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)從多根電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)中做(zuo)出(chu)明確判(pan)別。又(you)由于被(bei)識(shi)(shi)別電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)上(shang)的(de)(de)(de)(de)信(xin)號(hao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流強度全線都是(shi)一樣的(de)(de)(de)(de)，接(jie)收(shou)(shou)(shou)卡(ka)鉗在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)沿線所接(jie)收(shou)(shou)(shou)到(dao)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁信(xin)號(hao)強度*，識(shi)(shi)別的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)不受被(bei)識(shi)(shi)別電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)長度的(de)(de)(de)(de)限制(zhi)。

主要特點

本(ben)儀器由電纜(lan)識別發(fa)射機，電纜(lan)識別接(jie)收機、發(fa)射卡鉗和(he)接(jie)收卡鉗及輸(shu)(shu)(shu)出(chu)(chu)信號(hao)連(lian)(lian)接(jie)線組成(cheng)。它(ta)具有(you)大(da)(da)功率(lv)電流脈沖輸(shu)(shu)(shu)出(chu)(chu)；現場(chang)接(jie)收信號(hao)特征清晰(xi)，輕便靈(ling)活(huo)，靈(ling)敏度高，能(neng)有(you)效抑制現場(chang)工頻干擾；判斷(duan)準確(que)、快速；保護電路(lu)可靠，不(bu)怕輸(shu)(shu)(shu)出(chu)(chu)短路(lu)；大(da)(da)鉗口ф125適合(he)各種截(jie)面(mian)積的動力電纜(lan)；內(nei)部具有(you)大(da)(da)功率(lv)隔離(li)變(bian)壓器，操作者(zhe)與市(shi)電不(bu)存在任何電氣上的直接(jie)接(jie)觸。極大(da)(da)的保證了人(ren)身安全。帶電電纜(lan)識別時不(bu)需要斷(duan)開各電纜(lan)兩(liang)端與變(bian)配電設備間(jian)的連(lian)(lian)接(jie)，可在電纜(lan)處于帶電的狀態下進(jin)行在線識別，提高了識別的效率(lv)，大(da)(da)大(da)(da)減少了由于停電所造成(cheng)的直接(jie)和(he)間(jian)接(jie)的經濟損失(shi)。

與(yu)常(chang)規的(de)(de)識(shi)別(bie)儀(yi)不同，采用了的(de)(de)通信技術，在發射端采用單片(pian)(pian)機(ji)技術對發射信號(hao)(hao)進(jin)行(xing)編(bian)碼、功率(lv)驅動，將信號(hao)(hao)耦合到電(dian)(dian)纜(lan)上；接收機(ji)中(zhong)的(de)(de)單片(pian)(pian)機(ji)對接收的(de)(de)相(xiang)位編(bian)碼信號(hao)(hao)解碼和(he)相(xiang)位識(shi)別(bie)。根據目標電(dian)(dian)纜(lan)上的(de)(de)信號(hao)(hao)相(xiang)位特征的(de)(de)*性(xing)將目標電(dian)(dian)纜(lan)從(cong)一(yi)大束(shu)電(dian)(dian)纜(lan)中(zhong)識(shi)別(bie)出(chu)來(lai)。因此工作(zuo)性(xing)能可(ke)靠，對超(chao)長電(dian)(dian)纜(lan)也(ye)能做到準確判別(bie)，是一(yi)種輕小型(xing)、緊湊(cou)型(xing)、便攜式儀(yi)器。適用于各種類(lei)型(xing)的(de)(de)高低(di)壓動力電(dian)(dian)纜(lan)。
