Iyiphi kulezi zinkinga ezilandelayo okufanele inakwe lapho usebenzisa ukumelana nokufakwa kwe-insulation?
I-HV Hipot GD3000B I-Insulation Resistance Tester
Okokuqala, lapho sihlola ukumelana nokufakwa kwento ehlolwayo, sidinga ukwazi umthamo kanye nezinga le-voltage yento yokuhlola, futhi sihlanganise idatha yokuhlola phakathi neminyaka noma umbiko wokuhlola wasefekthri ukuze kube lula ukuqhathaniswa kwemiphumela yedatha.Ngaphambi kokuhlolwa, zama ukususa imikhondo efanelekile ngangokunokwenzeka ukuze ukhiphe ngokugcwele into ehloliwe ukuze uvimbele ithonya le-voltage esele ku-insulation resistance, futhi usebenzise utshwala ukuze usule ukungcola ebusweni bezintambo ezihloliwe ukuze uvimbele. ukwanda kokuvuza kwamanje futhi kuholele ekuphikisweni kokufakwa kwe-insulation.Uma kuqhathaniswa nokumelana kwangempela kokufakwa kwe-insulation, izinga lokushisa ngesikhathi sokuhlolwa lingu-18 ~ 26 ℃, kanti umswakama ungama-70%.Uma izinga lokushisa nomswakama kuphezulu kakhulu noma kuphansi kakhulu, imiphumela yokuhlolwa izothinteka.Khetha i-voltage ephumayo efanele ukuze ukale.Uma i-voltage iphansi kakhulu noma iphezulu kakhulu, izophinda ithinte idatha.
Lapho ukuvuza kwamanje kukhulu kakhulu, kuyadingeka ukwandisa indawo yokuvikela ukuvimbela ukumelana nokufakwa.isimo esiphansi.Ngesikhathi sokuhlolwa, linda okungaphezu kuka-30S noma lapho inani lamadijithi enani lokumelana lizinzile ukuze lifunde inani lokumelana.Kodwa-ke, ngenxa yomthamo ohlukile wento elinganisiwe, ubude benqubo yokumuncwa kwamanje kwe-DC kanye ne-polarization nakho kuhlukile.Ngokuvamile, isikhathi sokufunda ukumelana ne-insulation sihlukile.UGuodian Xigao uphakamise ukuthi abhekisele esimweni sangempela esizeni.Ngemuva kokuthi ukuhlolwa sekuqediwe, isigaba esihloliwe sidinga ukukhishwa ngokugcwele futhi, futhi isikhathi sokukhipha siba side sento edinga ukuphinde ihlolwe.Imvamisa yokumelana ne-insulation iphezulu kakhulu ekusetshenzisweni kwansuku zonke.Akunzima ukuyisebenzisa.Uma ukumelana ne-insulation kungenasikhathi, ungakubheka ngakunye ngokusebenzisa lezi zindlela ezingenhla.Uma inani lokumelana namanje lingakhuphuki ngemva kwesheke, kufanele kubhekwe ukuthi izinga lokufakwa kwe-insulation le-Low elihloliwe noma ukuhlukaniswa kwe-insulation.
