Isilinganiso se-Transformer sokumelana ne-DC siyingxenye ebalulekile yokuhlolwa kwe-transformer.Ngesilinganiso sokumelana ne-DC, kungenzeka ukuhlola ukuthi isekethe ye-conductive ye-transformer ayixhumene kahle yini, i-welding engalungile, ukwehluleka kwekhoyili namaphutha ezintambo kanye nochungechunge lwezinkinga.
I-HV Hipot GDZRS yochungechunge lomhloli wokumelana we-DC wezigaba ezintathu
Okubizwa ngokuthi ukumelana kwe-DC kwe-transformer kubhekisela enani lokumelana ne-DC yesigaba ngasinye sokuphenduka kwe-transformer.Inhloso yokuyilinganisa ukuhlola ukuthi ingabe ikhona yini i-inter-turn short circuit ngaphakathi kwamajika ezigaba ezintathu ze-transformer.Ngoba uma kukhona isifunda esifushane sesigaba-kuya-isigaba ngaphakathi kwe-transformer, i-short-circuit current izoba nkulu kakhulu, futhi kungenzeka kakhulu ukushisa i-transformer.
Kodwa-ke, uma kukhona isifunda esifushane phakathi kokuphenduka kwesinye sezigaba, i-short-circuit current ingaba mncane kakhulu, futhi ukuvikelwa kwegesi kwe-transformer kuzohamba, kodwa kunzima ukubona ukuthi i-transformer ngokwayo iyiphutha.
Ngalesi sikhathi, linganisa inani lokumelana ne-DC lesigaba ngasinye se-transformer, bese ngokuqhathanisa amanani okumelana nezigaba ezintathu, kulula ukwahlulela ukuthi kukhona i-inter-turn short circuit ngaphakathi.Uma inani lokumelana nezigaba lihluke kakhulu, kungenzeka iphutha le-inter-turn short-circuit likhulu kakhulu.Uma inani lokumelana kwesinye sezigaba likhulu kakhulu noma lingapheli, kusho ukuthi ikhoyili yalesi sigaba iphukile.Uma ukuphikiswa kwe-interphase kufana ngokuyisisekelo, kungenzeka ukuthi kube nokujikeleza okufushane phakathi kokujika kungakhishwa.
Ngokuvamile, lapho umthamo olinganiselwe we-transformer ungaguquki, ukumelana okukhulu kwe-DC, ukulahlekelwa kwethusi kukhulu futhi kubi kakhulu ukushisa kwe-transformer.Uma ukumelana kwe-DC kukhulu kakhulu, i-transformer ishisa kakhulu, futhi i-transformer ishisa kalula.
