Tsebo ea transformer

Transformer ke sesebelisoa se sebelisang molao-motheo oa induction ea motlakase ho fetola motlakase oa AC. Likarolo tsa eona tse ka sehloohong li kenyelletsa coil ea mantlha, coil ea bobeli le core ea tšepe.

Mosebetsing oa elektronike, hangata u ka bona moriti oa transformer, e tloaelehileng haholo e sebelisoa phepelong ea motlakase e le motlakase oa phetoho, ho itšehla thajana.

Ka bokhutšoanyane, karolelano ea motlakase ea likhoele tsa mantlha le tsa bobeli e lekana le karolelano ea ho reteleha ha likhoele tsa mantlha le tsa bobeli. Ka hona, haeba u batla ho ntša li-voltage tse fapaneng, u ka fetola karolelano ea ho reteleha ha likhoele.

Ho ya ka maqhubu a fapaneng a tshebetso a di-transformer, ka kakaretso di ka arolwa ka di-transformer tse nang le maqhubu a tlase le di-transformer tse nang le maqhubu a phahameng. Mohlala, bophelong ba letsatsi le letsatsi, maqhubu a motlakase o fetohang ke 50Hz. Re bitsa di-transformer tse sebetsang ho di-transformer tsena tse nang le maqhubu a tlase; maqhubu a sebetsang a di-transformer tse nang le maqhubu a phahameng a ka fihla ho mashome a kHz ho isa ho makgolo a kHz.

Bophahamo ba transformer e nang le maqhubu a phahameng bo bonyenyane haholo ho feta ba transformer e nang le maqhubu a tlase e nang le matla a tšoanang a tlhahiso.

Transformer ke karolo e kgolo haholo potolohong ya motlakase. Haeba o batla ho fokotsa bophahamo ba modumo ha o ntse o netefatsa matla a tlhahiso, o hloka ho sebedisa transformer ya maqhubu a phahameng. Ka hona, ditransformer tsa maqhubu a phahameng di sebediswa ho fetola phepelo ya motlakase.

Molao-motheo o sebetsang oa transformer ea maqhubu a phahameng le transformer ea maqhubu a tlase o tšoana, tseo ka bobeli li thehiloeng molao-motheong oa induction ea motlakase. Leha ho le joalo, mabapi le thepa, "li-core" tsa tsona li sebelisa thepa e fapaneng.

Karolo e ka hare ea tšepe ea transformer ea maqhubu a tlase hangata e na le maqephe a mangata a tšepe a silicon, ha karolo e ka hare ea tšepe ea transformer ea maqhubu a phahameng e entsoe ka thepa ea makenete ea maqhubu a phahameng (joalo ka ferrite). (Ka hona, karolo e ka hare ea tšepe ea transformer ea maqhubu a phahameng hangata e bitsoa karolo e ka hare ea makenete)

Potolohong ea phepelo ea motlakase e tsitsitseng ea DC, transformer ea maqhubu a tlase e fetisa lets'oao la maqhubu a sine.

Ha ho tjhentjha potoloho ya phepelo ya motlakase, transformer ya maqhubu a phahameng e fetisa letshwao la maqhubu a sekwere a pulse a maqhubu a phahameng.

Ka matla a lekantsoeng, karolelano pakeng tsa matla a tlhahiso le matla a ho kenya a transformer e bitsoa bokgoni ba transformer. Ha matla a tlhahiso a transformer a lekana le matla a ho kenya, bokgoni ke 100%. Ha e le hantle, transformer e jwalo ha e yo, hobane tahlehelo ya koporo le tshepe di teng, transformer e tla ba le tahlehelo e itseng.

Tahlehelo ea koporo ke eng?

Ka lebaka la hore khoele ea transformer e na le khanyetso e itseng, ha motlakase o feta ka har'a khoele, karolo ea matla e tla fetoha mocheso. Ka lebaka la hore khoele ea transformer e kobehile ka terata ea koporo, tahlehelo ena e boetse e bitsoa tahlehelo ea koporo.

Tahlehelo ea tšepe ke eng?

Tahlehelo ea tšepe ea transformer e kenyelletsa haholo-holo likarolo tse peli: tahlehelo ea hysteresis le tahlehelo ea eddy current; Tahlehelo ea hysteresis e bolela hore ha motlakase o fapanyetsanang o feta ka har'a coil, mela ea matla a makenete e tla hlahisoa ho feta ka har'a motheo oa tšepe, 'me limolek'hule tse ka hare ho motheo oa tšepe li tla hohlana ho hlahisa mocheso, kahoo li ja karolo ea matla a motlakase; Hobane mohala oa matla a makenete o feta ka har'a motheo oa tšepe, motheo oa tšepe le oona o tla hlahisa motlakase o bakoang. Hobane motlakase o ntse o potoloha, o boetse o bitsoa motlakase oa eddy, 'me tahlehelo ea motlakase oa eddy le eona e tla sebelisa matla a mang a motlakase.
