電纜測試儀怎么使用:電纜故障測試系統:電力(li)的輸送和有線通(tong)信(xin)的暢通(tong)有賴于電纜線路的正常運行。如果線路發生障礙,那就會造成電力和通信的中斷,如果不能馬上查出故障并且迅速予以排除故障,那就會很可能造成非常大的的經濟損失和不良的社會影響。因此,電纜故障測試儀是維護各種電纜的非常重要的測試工具。電力電纜故障智能測試儀采用了多種故障探測方法,應用當前 先進的電子技術成果,采用了計算機和特殊性電子技術,通過結合公司常久研制電纜測試儀的成功(gong)經(jing)驗而推出(chu)的智能(neng)化,功(gong)能(neng)全的新(xin)一代高科技(ji)產(chan)品。
為了能(neng)更(geng)好(hao)和更(geng)多(duo)查找故障點(dian),在(zai)探(tan)(tan)測(ce)(ce)到故障點(dian)時(shi)(shi),探(tan)(tan)測(ce)(ce)人員的(de)雙腳(jiao)要盡量(liang)拉開(kai)距離。以減小接(jie)地(di)(di)(di)(di)點(dian)的(de)面積再探(tan)(tan)測(ce)(ce)一(yi)段時(shi)(shi)間(jian)后(hou),如果(guo)發現指示燈亮度不夠時(shi)(shi),必(bi)須要充(chong)電(dian)后(hou)再進行探(tan)(tan)測(ce)(ce)。如果(guo)地(di)(di)(di)(di)埋(mai)(mai)線(xian)漏電(dian)故障點(dian)太多(duo)或對地(di)(di)(di)(di)埋(mai)(mai)線(xian)不能(neng)供電(dian)時(shi)(shi),可(ke)以用B型機進行探(tan)(tan)測(ce)(ce)。用B型機進行探(tan)(tan)測(ce)(ce)時(shi)(shi),應首(shou)先要把要測(ce)(ce)的(de)線(xian)路和高壓連(lian)線(xian)全部(bu)斷開(kai)。然(ran)后(hou)把大功率信號發射(she)器的(de)紅色(se)(se)接(jie)線(xian)柱(zhu),接(jie)在(zai)地(di)(di)(di)(di)埋(mai)(mai)線(xian)其(qi)中一(yi)根和多(duo)根線(xian)上,黑色(se)(se)接(jie)線(xian)柱(zhu)接(jie)上連(lian)線(xian),用長大約5-15公分的(de)鐵釘(ding)釘(ding)在(zai)地(di)(di)(di)(di)上( 好(hao)把接(jie)地(di)(di)(di)(di)的(de)地(di)(di)(di)(di)方用水灑濕),然(ran)后(hou)按以上步驟,就可(ke)進行探(tan)(tan)測(ce)(ce)。
除此(ci)之外,使用(yong)電(dian)(dian)纜(lan)故(gu)(gu)障(zhang)測(ce)試儀時(shi),首(shou)先在(zai)探測(ce)之前,要弄清漏電(dian)(dian)故(gu)(gu)障(zhang)線(xian)(xian)的性(xing)質,向線(xian)(xian)路送(song)(song)電(dian)(dian)。如(ru)果只是(shi)絕緣損(sun)壞向大地漏電(dian)(dian),線(xian)(xian)路不短路,不斷線(xian)(xian)時(shi),可用(yong)常規向線(xian)(xian)路送(song)(song)電(dian)(dian);如(ru)果線(xian)(xian)間短路且漏電(dian)(dian)或線(xian)(xian)間絕緣正常,有部分斷線(xian)(xian)且漏電(dian)(dian)時(shi),可將本路所有的線(xian)(xian)(三線(xian)(xian)或四線(xian)(xian))并接在(zai)一(yi)起,向線(xian)(xian)路單(dan)相送(song)(song)電(dian)(dian);如(ru)果對地絕緣良(liang)好,內(nei)芯(xin)(xin)斷線(xian)(xian)故(gu)(gu)障(zhang)時(shi),可將所有好線(xian)(xian)及斷芯(xin)(xin)故(gu)(gu)障(zhang)線(xian)(xian)的一(yi)端一(yi)并接地,由故(gu)(gu)障(zhang)線(xian)(xian)的另(ling)一(yi)端向故(gu)(gu)障(zhang)線(xian)(xian)送(song)(song)單(dan)相電(dian)(dian)源。
電纜測試儀需一人操作(zuo)。將電纜故(gu)障(zhang)測(ce)(ce)試儀的(de)(de)(de)耳機(ji)插(cha)頭(tou)插(cha)入儀器(qi)耳機(ji)孔,按下開關,指示燈亮。將探(tan)(tan)測(ce)(ce)板上的(de)(de)(de)連線(xian)分別接在(zai)(zai)紅(hong)黑(hei)接線(xian)柱(zhu)上,然后把(ba)探(tan)(tan)測(ce)(ce)板相碰(peng)幾下,同(tong)時(shi)(shi)耳機(ji)內應聽到(dao)(dao)咯叭聲(sheng),機(ji)器(qi)屬正(zheng)常。把(ba)帶釘的(de)(de)(de)探(tan)(tan)測(ce)(ce)板分別扣(kou)在(zai)(zai)探(tan)(tan)測(ce)(ce)員(yuan)的(de)(de)(de)左右腳上,做為(wei)探(tan)(tan)測(ce)(ce)器(qi)的(de)(de)(de)兩個接地(di)點(dian)(dian),然后就(jiu)可以對(dui)地(di)埋(mai)線(xian)進行探(tan)(tan)測(ce)(ce)。在(zai)(zai)地(di)埋(mai)線(xian)上方從(cong)線(xian)路(lu)的(de)(de)(de)一端(duan)向(xiang)另一端(duan)探(tan)(tan)測(ce)(ce),緩慢(man)向(xiang)前(qian)行走,在(zai)(zai)對(dui)地(di)絕緣良好的(de)(de)(de)線(xian)段,耳機(ji)基本無(wu)聲(sheng),在(zai)(zai)臨(lin)近故(gu)障(zhang)點(dian)(dian)(C)時(shi)(shi),聲(sheng)音(yin)(yin)逐漸由(you)小(xiao)到(dao)(dao)大(da),到(dao)(dao)故(gu)障(zhang)點(dian)(dian)(A)時(shi)(shi),聲(sheng)音(yin)(yin) 大(da),當越過故(gu)障(zhang)點(dian)(dian)到(dao)(dao)(B)時(shi)(shi),聲(sheng)音(yin)(yin)則由(you)大(da)變小(xiao)至無(wu)聲(sheng),然后可退回到(dao)(dao)聲(sheng)音(yin)(yin) 大(da)時(shi)(shi)的(de)(de)(de)地(di)方(A),此點(dian)(dian)即(ji)為(wei)漏電故(gu)障(zhang)點(dian)(dian)。
