Xa i-loop resistance tester (ekwabizwa ngokuba ngumvavanyi wokumelana noqhagamshelwano) eyenzelwe ngokomgaqo woyilo wendabuko wavavanywa kwintsimi, kwafunyaniswa ukuba kukho ingxaki eqhelekileyo.Xa isekethe yoqhagamshelo lombane womvavanyi ikwimeko embi okanye ikwisekethe evulekileyo, umvavanyi uya kubonisa ixabiso, kwaye ezi meko zilandelayo ziya kwenzeka:
I-HV HIPOT GDHL-200A/100A iAutomatic Loop Resistance Tester
(1) Ilophu yombane ivuliwe, kwaye akukho siphazamiso sinamandla sebala lombane kwindawo yovavanyo.Kule meko, ekubeni igalelo lombane wemowudi yokwahlukana yi-amplifier ngokusisiseko yi-0, ixabiso lokuvavanya eliboniswe sisixhobo lisondele kwi-0. Ukuba umvavanyi unamava ovavanyo olwaneleyo lwentsimi, unokugweba ukuba umgca wovavanyo olungaqhelekanga lwesixhobo sombane. isekethe ayiqhelekanga kwaye ibuyela kumbane wesixhobo.Emva kokuba indlela yovavanyo engaqhelekanga ingabandakanywa, umphumo wokugqibela wovavanyo oluchanekileyo unokufumaneka.
(2) Uqhagamshelwano lwesekethe yombane lubi.Kwiimeko ezininzi, ii-terminals ze-breaker circuit ziza kuvelisa ifilimu ye-oxide okanye ifilimu yeoli kwindawo yangaphandle ye-terminal emva kokusebenza kwexesha elide.Xa izithinteli zokuvavanya amandla ombane zibotshelelwa kwimicu yetheminali enjalo, unxibelelwano olubi lunokwenzeka.Xa ikliphu yovavanyo lwe-voltage ngokwayo ivelisa ukuchasana okuthile koqhagamshelwano, ixabiso lokumelana noqhagamshelwano liyafana nexabiso langaphakathi lokumelana nesampulu yombane wesekethe.iya kuba nefuthe elibi kwiziphumo zovavanyo.
3 .Ngeli xesha, ibhasi ephilayo idlula kwi-capacitor ngomoya njengephakathi, iphazamisa imigca emibini yovavanyo lombane womhloli.Ngenxa yokuphazamiseka, imigca yokufumana i-voltage ye-loop resistance tester mibini.Umbane wemowudi eyahlukileyo ubonakala ekupheleni.
