Bohlokoa ba ho lekanya khanyetso ea DC bakeng sa li-transformer ke bofe?

Tekanyo ea Transformer ea DC ho hanyetsa ke karolo ea bohlokoa ea tlhahlobo ea transformer.Ka tekanyo ea khanyetso ea DC, hoa khoneha ho hlahloba hore na potoloho ea conductive ea transformer ha e kopane hantle, welding e futsanehileng, ho hlōleha ha li-coil le liphoso tsa wiring le letoto la liphoso.

Seo ho thoeng ke khanyetso ea DC ea transformer e bua ka boleng ba ho hanyetsa ba DC ba karolo e 'ngoe le e' ngoe ea mapheo a transformer.Sepheo sa ho lekanya ke ho hlahloba hore na ho na le potoloho e khutšoanyane ea li-inter-turn ka har'a maqhubu a mararo a transformer.Hobane haeba ho e-na le potoloho e khutšoanyane ea karolo-to-phase ka hare ho transformer, nako e khutšoanyane ea potoloho e tla ba khōlō haholo, 'me ho ka etsahala hore e chese transformer.

Leha ho le joalo, haeba ho e-na le potoloho e khutšoanyane pakeng tsa ho fetoha ha e 'ngoe ea mekhahlelo, nako e khutšoanyane ea potoloho e ka' na ea e-ba nyenyane haholo, 'me tšireletso ea khase ea transformer e tla tsamaea, empa ho thata ho bona hore na transformer ka boeona e fosahetse.
Ka nako ena, lekanya boleng ba khanyetso ea DC ea karolo e 'ngoe le e' ngoe ea transformer, ebe ka ho bapisa litekanyetso tsa ho hanyetsa mekhahlelo e meraro, ho bonolo ho ahlola hore na ho na le potoloho e khutšoanyane ea inter-turn ka hare.Haeba boleng ba ho hanyetsa li-inter-phase bo fapane haholo, monyetla oa ho ba le phoso ea "inter-turn short-circuit" e kholo haholo.Haeba boleng ba ho hanyetsa ba mekhahlelo e 'ngoe bo le boholo haholo kapa bo sa feleng, ho bolela hore coil ea mohato ona e robehile.Haeba ho hanyetsa interphase ha e le hantle ho tšoana, monyetla oa hore ho be le potoloho e khutšoanyane pakeng tsa ho chenchana ho ka tlosoa.
Ka kakaretso, ha matla a lekantsoeng a transformer a sa fetohe, khanyetso e kholo ea DC, tahlehelo e kholo ea koporo le ho futhumala ho tebileng haholoanyane.Haeba khanyetso ea DC e le khōlō haholo, transformer e chesa haholo, 'me transformer e chesoa habonolo.
