Indlela Yokusingatha I-Transformer Core Grounding

1) Izindlela Zokuxazulula Izinkinga Zesikhashana (Lapho Isiguquli Singakwazi Ukuvalwa):

① Ukunqamula okwesikhashana intambo yaphansi: Uma umthofi ophansi wangaphandle ukhona futhi iphutha lamanje likhulu ngokuqhathaniswa, i-transformer ingasebenza ngentambo yaphansi inqanyulwe okwesikhashana. Kodwa-ke, ukuqapha kufanele kuqiniswe ukuze kuvinjwe umnyombo ekuthuthukiseni amandla okuntanta uma iphutha linyamalala.

② Ukufaka i-rheostat (i-resistor esishelelayo): Uma iphutha lokusekela amaphuzu amaningi liwuhlobo olungazinzile, i-rheostat ingaxhunywa ngochungechunge ngentambo yaphansi yokusebenza ukuze kukhawulwe yamanje ibe ngaphansi kuka-1A. Inani elifanele lokumelana linqunywa ngokuhlukanisa i-voltage elinganisiwe (etholakala lapho kuvulwa ucingo oluvamile lwaphansi) ngomsinga osocingweni lwaphansi.

③ Ukuqapha i-chromatography yegesi: Ukuhlaziywa kwegesi encibilikisiwe (i-DGA) kufanele kusetshenziselwe ukuqapha izinga lokukhiqiza igesi endaweni yephutha.

④ Ukususa i-grounding shunt: Uma iphutha lapho iphuzu litholakala ngesilinganiso kodwa lingakwazi ukulungiswa ngokushesha, i-shunt eyisisekelo evamile ingathuthelwa endaweni efana ncamashi nephuzu lephutha ukuze kwehliswe kakhulu amandla ajikelezayo.

(2) Izinyathelo Zokugcina Eziphelele:
Uma ukuqapha kukhombisa iphutha lesisekelo lamaphuzu amaningi, ama-transformer angathathwa ungaxhunyiwe ku-inthanethi kufanele zivalwe ngokushesha ukuze kuqedwe ngokuphelele iphutha. Izinyathelo ezithile zokulungisa kufanele zihambisane nohlobo kanye nembangela ye-grounding yamaphuzu amaningi. Kodwa-ke, kwezinye izimo, iphuzu lephutha alikwazi ukutholakala ngisho nangemva kokuba umnyombo uphakanyisiwe ngesikhathi sokuhamba kwamandla. Ukuze kutholakale ngokunembile indawo okusekelwe kuyo, izindlela ezilandelayo zingasetshenziswa esizeni:

① Indlela ye-DC: Nqamula ibhande lokuxhuma phakathi komgogodla nezinsimbi, bese usebenzisa i-6V DC kuwo wonke amashidi ensimbi ye-silicon nhlangothi zombili zejoka. Bese, sebenzisa i-voltmeter ye-DC ukukala i-voltage phakathi kwamashidi ensimbi ye-silicon esigabeni ngasinye ngokulandelana. Lapho i-voltage ifunda uziro noma imitha ikhombisa i-polarity ehlehlayo, leyo ndawo ethile ingabonakala njengendawo yokubeka iphutha.

② Indlela ye-AC: Xhuma i-low-voltage winding ye-transformer kugesi ongu-220~380V AC ukuze usungule i-flux kazibuthe kumongo (qinisekisa ukuthi ibhande lokuxhuma phakathi komgogodla nezinsimbi livuliwe). Uma kukhona iphutha lokusekela amaphuzu amaningi, i-current izotholwa kusetshenziswa i-milliammeter. Hambisa i-milliammeter eduze kwejoka ezigabeni ezihlukahlukene zokulinganisa iphuzu-ngephuzu; lapho yamanje ifunda uziro ku-milliammeter, leyo ndawo iyiphoyinti lephutha.
