Apo iyo loop resistance tester (inonziwo contact resistance tester) yakagadzirwa maererano netsika yekugadzira yakaedzwa mumunda, zvakaonekwa kuti pane dambudziko rinowanzoitika.Kana iyo voltage yekubatanidza dunhu reye tester iri mukusaonana kana kuvhurika dunhu, muyedzi anoratidzawo kukosha, uye anotevera mamiriro achaitika:
HV HIPOT GDHL-200A/100A Automatic Loop Resistance Tester
(1) Voltage loop yakavhurika, uye hapana simba remagetsi rinokanganisa panzvimbo yekuyedza.Muchiitiko ichi, sezvo iyo differential mode voltage inopinda neamplifier inongova 0, kukosha kwekuedza kunoratidzwa nechombo chiri pedyo ne 0. Kana muongorori ane ruzivo rwakakwana rwekuongorora munda, anogona kutonga kuti mutsara wekuedza usina kujairika wechikwata chemagetsi. dunhu harina kujairika uye dzokera kune voltage mudziyo.Mushure mekunge nzira yekuedza isina kujairika yabviswa, mhinduro yekupedzisira yekuyedza inogona kuwanikwa.
(2) Kubata kweiyo voltage circuit kwakashata.Muzviitiko zvakawanda, materminals emugero wedunhu anoburitsa oxide firimu kana mafuta firimu pane yekunze kweiyo terminal mushure mekushanda kwenguva refu.Kana magetsi ekuedza mabhanhire ematunhu anopikisa akasungirirwa kune akadaro terminal mitsetse, kutadza kubata kunogoneka.Kana iyo voltage test clip pachayo ichiburitsawo imwe yekubata kuramba, iyo yekubata kuramba kukosha kwakafanana neiyo yemukati kuramba kukosha kweiyo voltage sampling wedunhu.ichave nechakaipa pamhedzisiro yebvunzo.
(3) Iyo voltage loop idunhu rakavhurika kana kudhumhana kwakashata (kana dunhu rakavhurika, zvinoonekwa kuti yekubata kuramba r1 haina magumo), uye kune kwakasimba kupindira kwemagetsi panzvimbo yekuyedza, senge bhazi mhenyu. .Panguva ino, bhazi mhenyu rinopfuura nemu capacitor nemhepo sepakati, ichikanganisa mitsara miviri yekuyedza voltage ye tester.Nekuda kwekukanganisika, mitsara yekutora magetsi yeloop resistance tester maviri.The differential mode voltage inoonekwa pamagumo.
