Ho na le litlhoko tse tsamaellanang tsa tekheniki bakeng sa mefuta e fapaneng ea li-transformer, tse ka hlahisoang ke litekanyetso tse tsamaellanang tsa tekheniki.Mohlala, litekanyo tsa mantlha tsa tekheniki ea motlakase oa motlakase li kenyelletsa: matla a lekantsoeng, karo-karolelano ea voltage le voltage, maqhubu a lekantsoeng, boemo ba mocheso o sebetsang, ho phahama ha mocheso, sekhahla sa taolo ea motlakase, ts'ebetso ea ho kenella le ho hanyetsa mongobo.Bakeng sa li-transformer tse fokolang hangata, lintlha tse ka sehloohong tsa tekheniki ke: karo-karolelano ea phetoho, litšoaneleho tsa maqhubu, ho sotha ho se nang moeli, tšireletso ea magnetic le electrostatic shielding, katleho, joalo-joalo.
Mekhahlelo ea mantlha ea transformer e kenyelletsa karolelano ea motlakase, litšobotsi tsa maqhubu, matla a lekantsoeng le katleho.
（1）Tekanyetso ea motlakase
Kamano pakeng tsa tekanyo ea motlakase n ea transformer le ho thinya le motlakase oa maqhubu a mantlha le a bobeli ke ka tsela e latelang: n=V1/V2=N1/N2 moo N1 e leng matsoelintsoeke a mantlha (ea mantlha) a transformer, N2 ke matsoelintsoeke a bobeli (a bobeli), V1 ke motlakase lintlheng tse peli tsa matsoelintsoeke a mantlha, 'me V2 ke motlakase lipheletsong tse peli tsa matsoelo a bobeli.Karo-karolelano ea motlakase n ea transfoma ea mohato oa ho nyoloha e ka tlase ho 1, tekanyo ea motlakase n ea transfoma e theohang e kholo ho feta 1, 'me tekanyo ea motlakase ea transformer ea ho itšehla thajana e lekana le 1.
（2）Matla a lekantsoeng P Parameter ena hangata e sebelisoa bakeng sa li-transformer tsa matla.E bua ka matla a tlhahiso ha motlakase oa motlakase o ka sebetsa nako e telele ntle le ho feta mocheso o boletsoeng tlas'a maqhubu a sebetsang a sebetsang le motlakase.Matla a lekantsoeng a transformer a amana le sebaka sa karolo ea tšepe ea tšepe, bophara ba terata ea enamelled, joalo-joalo Transformer e na le sebaka se seholo sa karolo ea tšepe, bophara ba terata ea enamelled le matla a maholo a tlhahiso.
（3）Letšoao la khafetsa Letšoao la khafetsa le bolela hore transformer e na le mofuta o itseng oa maqhubu a ts'ebetso, 'me li-transformer tse nang le maqhubu a fapaneng a ts'ebetso li ke ke tsa fapanyetsanoa.Ha transformer e sebetsa ka nģ'ane ho mefuta ea eona ea maqhubu, mocheso o tla phahama kapa transformer e ke ke ea sebetsa ka tloaelo.
（4）Ho sebetsa hantle ho bolela karo-karolelano ea matla a tlhahiso le matla a ho kenya a transformer ka mojaro o lekantsoeng.Boleng bona bo lekana le matla a phallo ea transformer, ke hore, matla a maholo a ho hlahisa a transformer, a phahame ka katleho;Matla a fokolang a tlhahiso ea transformer, a fokotsa katleho.Boleng bo sebetsang ba transformer hangata bo pakeng tsa 60% le 100%.
Ka matla a lekantsoeng, karo-karolelano ea matla a tlhahiso le matla a ho kenya a transformer e bitsoa katleho ea transformer, e leng

Hokaeη Na ho sebetsa hantle ha transformer;P1 ke matla a ho kenya 'me P2 ke matla a tsoang.
Ha matla a tlhahiso ea P2 ea transformer a lekana le matla a ho kenya P1, katlehoη E lekana le 100%, transformer e ke ke ea hlahisa tahlehelo leha e le efe.Empa ha e le hantle, ha ho na transformer e joalo.Ha transformer e fetisa matla a motlakase, e lula e hlahisa tahlehelo, eo haholo-holo e kenyelletsang tahlehelo ea koporo le tahlehelo ea tšepe.
Ho lahleheloa ke koporo ho bolela tahlehelo e bakoang ke ho hanyetsa ha coil ea transformer.Ha motlakase o futhumatsoa ka ho hanyetsa li-coil, karolo ea matla a motlakase e tla fetoloa matla a mocheso ebe e lahleheloa.Kaha khoele ka kakaretso e entsoe ka terata ea koporo e kentsoeng, e bitsoa tahlehelo ea koporo.
Ho lahleheloa ke tšepe ea transformer ho kenyelletsa lintlha tse peli.E 'ngoe ke tahlehelo ea hysteresis.Ha motlakase oa AC o feta ka har'a transformer, tataiso le boholo ba matla a khoheli a matla a fetang ka har'a letlapa la tšepe ea silicon ea transformer e tla fetoha ka tsela e nepahetseng, e leng se etsang hore limolek'hule tse ka hare ho letlapa la tšepe la silicon li suthele khahlanong le tse ling le ho lokolla matla a mocheso. kahoo ho lahleheloa ke karolo ea matla a motlakase, e bitsoang tahlehelo ea hysteresis.E 'ngoe ke tahlehelo ea hona joale ea eddy, ha transformer e sebetsa.Ho na le khoele ea matla a khoheli e fetang mokokotlong oa tšepe, 'me motlakase o kentsoeng o tla hlahisoa sefofaneng se pota-potileng matla a khoheli a matla.Kaha hona joale sena se etsa sekoti se koetsoeng 'me se potoloha ka sebopeho sa whirlpool, se bitsoa eddy current.Ho ba teng ha eddy current ho etsa hore mokokotlo oa tšepe o chese ebe o ja matla, a bitsoang eddy current loss.
Ho sebetsa hantle ha transformer ho amana haufi-ufi le boemo ba matla a transformer.Ka kakaretso, ha matla a le kholoanyane, tahlehelo le matla a tsoang li fokola, 'me matla a holimo a phahame.Ho e-na le hoo, ha matla a le manyenyane, a fokotsa katleho.
