Tahlehelo ea Transformer ke Eng?

Tahlehelo ea transformer ea motlakase e kenyelletsa haholo-holo tahlehelo ea koporo le tahlehelo ea tšepe. Lebaka ke hobane lisebelisoa life kapa life tsa motlakase li tla hlahisa tahlehelo nakong ea ts'ebetso e telele, 'me li-transformer tsa motlakase le tsona ha li joalo.

Tšenyo ea tšepe ke eng?

Ho fapana le tahlehelo ea koporo, tahlehelo ea tšepe ea transformer ha e itšetlehe ka lintlha tse kang ho kobeha le boholo ba hona joale. Ho ea ka pono ea lebitso, tšenyo ea tšepe e amana haufi-ufi le tšepe, e hlahisoa ke karolo ea tšepe. Tahlehelo ea tšepe ea transformer e boetse e tsejoa e le "tahlehelo ea mojaro o se nang mojaro", e leng hobane tahlehelo ea tšepe e lula e le teng ka har'a transformer, ebang ke mojaro o felletseng kapa ha ho mojaro o le mong, 'me ke ea tahlehelo e tsitsitseng ea transformer. Leha ho le joalo, nakong ea ts'ebetso ea mojaro, tahlehelo ea matla e tla fokotseha ha matla a tšimo ea motlakase a fokotseha.

Tlhophiso ea tahlehelo ea tšepe ea transformer

Tahlehelo ea tšepe ea transformer e arotsoe ka tahlehelo ea hysteresis le tahlehelo ea eddy current.

Tahlehelo ea Hysteresis

Molao-motheo oa ts'ebetso oa transformer o thehiloe molao-motheong oa tlhahiso ea motlakase ho fihlela ho phahama le ho theoha ha motlakase le liphetoho tsa hona joale. Phallo ea makenete ka har'a transformer e phalla holim'a motheo oa tšepe. Motheo oa tšepe o na le khanyetso ea makenete khahlanong le phallo ea makenete, joalo ka ha mokhanni a na le khanyetso khahlanong le hona joale. Ka mokhoa o ts'oanang, mocheso le oona o tla hlahisoa, 'me tahlehelo ena e bitsoa "tahlehelo ea hysteresis".

Tahlehelo ea hona joale ea Eddy

Ha motlakase o sebediswa ho kobeha ha motlakase wa transformer, phallo ya makenete e hlahiswang ke koili e phalla kahare ho tshepe. Hobane motheo ka bowona ke motsamaisi, matla a motlakase a hlahiswa ka sefofaneng se otlolohileng ho mola wa matla a makenete. Matla ana a etsa sekgoqetsane se kwetsweng karolong e tsheletseng ya motheo, e leng se hlahisang motlakase. Motlakase ona o sebetsa jwalo ka motlakase o potolohang, ka hona lebitso "vortex". Tahlehelo e bakwang ke motlakase wa eddy e bitswa "tahlehelo ya motlakase wa eddy". Ke hobane motheo o etsa maqhubu a eddy moo o etswang lakane e tshesane. Hobane motlakase o mosesaane, kganyetso e hodimo, matla a motlakase a theoha.

Mabaka a susumetsang tahlehelo ea tšepe ea transformer

Tahlehelo ea koporo

Koporo e bapala karolo ea bohlokoa ho li-transformer. Hangata lithapo tsa koporo li sebelisoa ho winding ha li-transformer. "Tahlehelo ea koporo" ho transformer ke tahlehelo e bakoang ke lithapo tsa koporo. "Tahlehelo ea koporo" ea transformer e boetse e bitsoa tahlehelo ea mojaro. Seo ho thoeng ke tahlehelo ea mojaro ke tahlehelo e feto-fetohang le liphetoho.

E fetoha ka phetoho ea hona joale, tahlehelo ea koporo (tahlehelo ea mojaro) ke tahlehelo e feto-fetohang, 'me hape ke tahlehelo e kholo ts'ebetsong ea transformer.

Mabaka a susumetsang tahlehelo ea koporo ea transformer

• Boholo ba hona joale: Joalokaha ho boletsoe ka holimo, tahlehelo ea koporo e lekana le sekwere sa hona joale, kahoo boholo ba hona joale ke ntlha ea bohlokoa e amang tahlehelo ea koporo.
• Khanyetso ea ho kobeha: Khanyetso ea ho kobeha e ama tahlehelo ea koporo ka kotloloho. Ha khanyetso e le kholoanyane, tahlehelo ea koporo e ba kholoanyane.
• Palo ea mealo ea koili: Ha mealo ea koili e le mengata, tsela ea hore motlakase o phalle ka har'a koili e telele, 'me khanyetso e tla eketseha ka ho lekana, e leng se fellang ka tahlehelo e eketsehileng ea koporo.
• Maqhubu a ho chencha: Tšusumetso ea maqhubu a ho chencha tahlehelong ea koporo ea transformer e amana ka ho toba le liparamente tsa kabo le litšobotsi tsa mojaro oa transformer.
