Ho li-transformer tse phahameng haholo, phello e tla ba efe haeba boleng ba inductance bo feta moeli o fanoeng?

 

Transformer e phahameng ea maqhubuke sesebelisoa sa elektronike se sebelisetsoang ho fetola motlakase le motlakase. E atisa ho sebelisoa lipuisanong tse se nang mohala, ho fetola matla, lethepa ea elektronike. Holi-transformer tse phahameng haholo, khetho le taolo ea inductance ke ea bohlokoa haholo hobane e tla ama ka ho toba tshebetso le botsitso ba transformer. Haeba inductance e feta tekanyo e fanoeng, liphello tse latelang li tla etsahala:

1. Magnetic core saturation: Inli-transformer tse phahameng haholo, li-cores tsa tšepe kapa lisebelisoa tsa makenete hangata li sebelisoa ho eketsainductance. Ha inductance e feta moeli o itseng, mokokotlo o ka tlala. Khokahano ea mantlha e baka flux density saturation, e lebisang ho se tsitseng le ho sotha ho inductor. Sena se ka baka ho se tsitse le ho senyeha ha harmonic ho motlakase oa tlhahiso.

2. Litahlehelo tse eketsehileng: Mokotla le coil ka hare ho inductor li tla hlahisa tahlehelo e itseng, hangata ka mokhoa oa tahlehelo ea koporo le tahlehelo ea tšepe. Ha inductance e phahame haholo, hona joale ka har'a coil e ba kholoanyane, e bakang tahlehelo e ngata ea koporo. Ho feta moo, ho tlala ha core ho tla boela ho lebise ho eketseha ha tahlehelo ea tšepe. Sena se tla etsa horehigh frequency transformere sa sebetseng hantle.

3. Bothata ba mocheso: Litahlehelo tse eketsehileng li tla boela li etse hore transformer e futhumale haholo. Haeba e sa pholile hantle kapa ka mocheso o sa lekaneng oa mocheso, sena se ka etsa hore mocheso o phahame, qetellong o ama bophelo le ho tšepahala ha transformer e phahameng-frequency.

4. Bothata ba Taolo: Likopong tse phahameng-frequency, litekanyetso tse nepahetseng tsa inductance li atisa ho hlokoa ho netefatsa hore transformer e tla sebetsa ka har'a litlhaloso tsa moralo. Haeba boleng ba inductance bo feta tekanyo e fanoeng, ho e lokisa ho tla ba thata le ho feta 'me transformer e ka' na ea hloka ho tsosolosoa.

5. Litaba tsa Harmonic: Ts'ebetso ea harmonic ea li-transformer tse phahameng-frequency ke tsa bohlokoa haholo bakeng sa lisebelisoa tse ling, tse kang mekhoa ea puisano e se nang mohala. Khetho e sa nepahalang ea boleng ba inductor e ka baka ho sotha ha harmonic, ho ama boleng ba puisano.

Ho qoba mathata ana, khetho eainductorboleng bo hloka ho nahanoa ka hloko ha ho etsoa li-transformer tse phahameng-frequency le ho netefatsa hore e ka har'a sebaka sa moralo. Ka tloaelo, khetho ea boleng ba inductor e tla angoa ke lintlha tse kang litlhoko tsa moralo, maqhubu a ts'ebetso, motlakase oa ho kenya, le motlakase o tsoang. Ka moralo oa 'nete, papiso ea potoloho le netefatso ea liteko hangata lia hlokahala ho netefatsa hore khetho ea boleng ba inductor e nepahetse ebile e ka kopana le ts'ebetso le botsitso.

Bakeng sa lipotso tsa sehlahisoa, ka kopo, shebaleqephe la sehlahisoa, o boetse o amohelehile hoiteanye le ronaka tlhaiso-leseling e ka tlase, re tla u araba nakong ea 24.
