Transformer ke sesebelisoa se sebelisang molao-motheo oa motlakase oa motlakase ho fetola motlakase oa AC.Likarolo tsa eona tse ka sehloohong li kenyelletsa coil ea mantlha, coil ea bobeli le tšepe ea tšepe.
Mosebetsing oa elektronike, hangata u ka bona moriti oa transformer, e tloaelehileng ka ho fetisisa e sebelisoa phepelong ea motlakase e le motlakase oa ho fetola, ho itšehla thajana.
Ka bokhutšoanyane, karo-karolelano ea li-voltage tsa li-coil tsa mantlha le tsa bobeli li lekana le karo-karolelano ea li-coil tsa mantlha le tsa bobeli.Ka hona, haeba u batla ho hlahisa li-voltages tse fapaneng, u ka fetola karo-karolelano ea li-coil.
Ho ea ka mefuta e fapaneng ea ho sebetsa ea li-transformer, ka kakaretso li ka aroloa ka li-transformer tse tlaase-frequency le li-high-frequency transformer.Ka mohlala, bophelong ba letsatsi le leng le le leng, maqhubu a motlakase a fetohang hona joale ke 50Hz.Re bitsa li-transformer tse sebetsang ka maqhubu ana a fokolang a fokolang;Maqhubu a ho sebetsa a transformer ea maqhubu a phahameng a ka fihla ho mashome a kHz ho makholo a kHz.
Bophahamo ba transformer ea maqhubu a phahameng e nyane haholo ho feta ea transfrequency e tlase e nang le matla a tšoanang a tlhahiso.
Transformer ke karolo e batlang e le kholo ho potoloho ea matla.Haeba u batla ho etsa hore molumo o be nyane ha o ntse o netefatsa matla a tlhahiso, o hloka ho sebelisa transformer e phahameng haholo.Ka hona, li-transformer tsa maqhubu a phahameng li sebelisoa ho fetola lisebelisoa tsa motlakase.
Molao-motheo oa ts'ebetso oa li-transformer tse phahameng le li-frequency tse tlase li ts'oana, tseo ka bobeli li ipapisitseng le molao-motheo oa induction ea motlakase.Leha ho le joalo, mabapi le lisebelisoa, "li-cores" tsa bona li sebelisa lisebelisoa tse fapaneng.
Mokotla oa tšepe oa transfrequency e tlase hangata o kentsoe ka lishiti tse ngata tsa tšepe tsa silicon, athe tšepe ea motlakase ea maqhubu a phahameng e entsoe ka lisebelisoa tse phahameng tsa maqhubu (tse kang ferrite).(Ka hona, motheo oa tšepe oa transformer ea maqhubu a phahameng hangata o bitsoa magnetic core)
Sebakeng sa DC se tsitsitseng sa phepelo ea matla a motlakase, sesebelisoa sa maqhubu a tlase se fetisa lets'oao la sine wave.
Ha o fetola potoloho ea phepelo ea motlakase, sefetoleli se phahameng sa maqhubu se fetisa lets'oao le phahameng la maqhubu a maqhubu a sekwere.
Ka matla a lekantsoeng, karo-karolelano pakeng tsa matla a tlhahiso le matla a ho kenya a transformer e bitsoa katleho ea transformer.Ha matla a tlhahiso ea transformer a lekana le matla a ho kenya, katleho ke 100%.Ha e le hantle, transformer e joalo ha e eo, hobane tahlehelo ea koporo le tahlehelo ea tšepe e teng, transformer e tla ba le tahlehelo e itseng.
Ho lahleheloa ke koporo ke eng?
Hobane coil ea transformer e na le khanyetso e itseng, ha hona joale e feta ka coil, karolo ea matla e tla fetoha mocheso.Hobane khoele ea transformer e entsoe ka terata ea koporo, tahlehelo ena e boetse e bitsoa tahlehelo ea koporo.
Ho lahleheloa ke tšepe ke eng?
Ho lahleheloa ke tšepe ea transformer haholo-holo ho kenyelletsa likarolo tse peli: tahlehelo ea hysteresis le tahlehelo ea hona joale ea eddy;Ho lahleheloa ke Hysteresis ho bolela hore ha motlakase o fapanyetsana o feta har'a coil, ho tla hlahisoa melapo ea matla a khoheli hore e fete ka har'a mokokotlo oa tšepe, 'me limolek'hule tse ka hare ho mokokotlo oa tšepe li tla hohlana ho hlahisa mocheso, kahoo li ja karolo ea matla a motlakase;Hobane matla a khoheli a feta ka har'a mokokotlo oa tšepe, mokokotlo oa tšepe o tla hlahisa hona joale.Hobane hona joale ho ntse ho pota-pota, e boetse e bitsoa eddy current, 'me tahlehelo ea hona joale ea eddy e tla boela e je matla a mang a motlakase.
