主要特點

本儀器(qi)由電(dian)(dian)(dian)纜(lan)(lan)(lan)識(shi)別(bie)(bie)發射機，電(dian)(dian)(dian)纜(lan)(lan)(lan)識(shi)別(bie)(bie)接(jie)收(shou)機、發射卡(ka)鉗和接(jie)收(shou)卡(ka)鉗及輸(shu)出(chu)信(xin)號(hao)(hao)連接(jie)線組成。它具有大(da)(da)功率電(dian)(dian)(dian)流脈沖輸(shu)出(chu)；現(xian)場接(jie)收(shou)信(xin)號(hao)(hao)特征清(qing)晰，輕便靈活(huo)，靈敏(min)度高，能有效抑制現(xian)場工頻干擾；判斷(duan)準確、快速；保護電(dian)(dian)(dian)路可(ke)靠，不(bu)(bu)怕輸(shu)出(chu)短(duan)路；大(da)(da)鉗口ф125適合各種截面積的(de)(de)動力電(dian)(dian)(dian)纜(lan)(lan)(lan)；內部具有大(da)(da)功率隔離變(bian)壓器(qi)，操作者與市電(dian)(dian)(dian)不(bu)(bu)存在(zai)任何電(dian)(dian)(dian)氣上的(de)(de)直接(jie)接(jie)觸。極大(da)(da)的(de)(de)保證了(le)人身安(an)全。帶電(dian)(dian)(dian)電(dian)(dian)(dian)纜(lan)(lan)(lan)識(shi)別(bie)(bie)時(shi)不(bu)(bu)需要(yao)斷(duan)開各電(dian)(dian)(dian)纜(lan)(lan)(lan)兩端與變(bian)配電(dian)(dian)(dian)設備間的(de)(de)連接(jie)，可(ke)在(zai)電(dian)(dian)(dian)纜(lan)(lan)(lan)處于(yu)帶電(dian)(dian)(dian)的(de)(de)狀態下進行在(zai)線識(shi)別(bie)(bie)，提高了(le)識(shi)別(bie)(bie)的(de)(de)效率，大(da)(da)大(da)(da)減(jian)少了(le)由于(yu)停電(dian)(dian)(dian)所(suo)造成的(de)(de)直接(jie)和間接(jie)的(de)(de)經濟(ji)損失。

與常規的(de)(de)識別儀(yi)不(bu)同，采用(yong)了的(de)(de)通(tong)信技(ji)術(shu)，在(zai)發射端采用(yong)單(dan)片機(ji)技(ji)術(shu)對(dui)發射信號(hao)進行編(bian)碼(ma)、功率驅動(dong)，將信號(hao)耦(ou)合(he)到電(dian)(dian)纜(lan)上(shang)；接收(shou)機(ji)中的(de)(de)單(dan)片機(ji)對(dui)接收(shou)的(de)(de)相位(wei)編(bian)碼(ma)信號(hao)解碼(ma)和相位(wei)識別。根據(ju)目標(biao)電(dian)(dian)纜(lan)上(shang)的(de)(de)信號(hao)相位(wei)特征的(de)(de)*性將目標(biao)電(dian)(dian)纜(lan)從一(yi)大(da)束(shu)電(dian)(dian)纜(lan)中識別出(chu)來(lai)。因此工作性能可(ke)靠(kao)，對(dui)超長電(dian)(dian)纜(lan)也能做到準(zhun)確判別，是一(yi)種輕(qing)小型、緊(jin)湊型、便攜式儀(yi)器。適用(yong)于各種類型的(de)(de)高低壓動(dong)力(li)電(dian)(dian)纜(lan)。

 工作原理

發(fa)射機(ji)(ji)和接(jie)收(shou)(shou)機(ji)(ji)采用(yong)單片機(ji)(ji)編(bian)碼、解碼技(ji)術(shu)和廣泛應用(yong)在通信(xin)領(ling)域里的(de)(de)(de)(de)PSK技(ji)術(shu)。在發(fa)射卡鉗(qian)(qian)上(shang)發(fa)射平(ping)均(jun)值為(wei)0 的(de)(de)(de)(de)相(xiang)(xiang)位(wei)編(bian)碼信(xin)號(hao)，接(jie)收(shou)(shou)機(ji)(ji)中的(de)(de)(de)(de)單片機(ji)(ji)對接(jie)收(shou)(shou)的(de)(de)(de)(de)信(xin)號(hao)經(jing)過(guo)硬件和軟(ruan)件的(de)(de)(de)(de)濾波后，再進行相(xiang)(xiang)位(wei)識(shi)別。將發(fa)射卡鉗(qian)(qian)和接(jie)收(shou)(shou)卡鉗(qian)(qian)的(de)(de)(de)(de)箭頭指(zhi)(zhi)向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)終(zhong)端，當接(jie)收(shou)(shou)機(ji)(ji)卡鉗(qian)(qian)鉗(qian)(qian)住某根(gen)(gen)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，接(jie)收(shou)(shou)機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)右偏，同時伴有(you)聲光指(zhi)(zhi)示(shi)。而鉗(qian)(qian)住其(qi)它(ta)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)左(zuo)偏，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)方向(xiang)與被(bei)識(shi)別電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)方向(xiang)相(xiang)(xiang)反，沒有(you)聲光指(zhi)(zhi)示(shi)。這就體現了被(bei)識(shi)別的(de)(de)(de)(de)目標電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)*性。很容(rong)易將被(bei)識(shi)別電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)從多根(gen)(gen)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)中做出明確(que)判別。又由(you)于(yu)被(bei)識(shi)別電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)上(shang)的(de)(de)(de)(de)信(xin)號(hao)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)強(qiang)度全(quan)線(xian)都是一樣的(de)(de)(de)(de)，接(jie)收(shou)(shou)卡鉗(qian)(qian)在電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)沿線(xian)所(suo)接(jie)收(shou)(shou)到的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)磁信(xin)號(hao)強(qiang)度*，識(shi)別的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)不受被(bei)識(shi)別電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)長度的(de)(de)(de)(de)限制。
