Transformer e sebelisoang hangata konokonos hangata li entsoe ka lishiti tsa tšepe tsa silicon. Silicon steel ke mofuta oa tšepe e nang le silicon (silicon e boetse e bitsoa silicon), ‘me boleng ba eona ba silicon ke 0.8 ho 4.8%. Silicon tšepe e sebelisoa e le thepa tšepe motheo oa transformer hobane tšepe ea silicon ka boeona ke ntho ea makenete e nang le matla a matla a khoheli. Ho coil e matlafalitsoeng, e ka hlahisa matla a maholo a ho kenya matla a khoheli, kahoo a fokotsa molumo oa transformer.

Rea tseba hore transformer ea ‘nete e lula e sebetsa sebakeng sa AC, le matla ke tahlehelo ha se feela khanyetso ea coil, empa hape le ho tšepe mantlha e hoketsoeng ke motlakase o fapanyetsanang. Matla ke tahlehelo mokokotlong oa tšepe hangata o bitsoa “tahlehelo ea tšepe”. Ho lahleheloa ke tšepe ho bakoa ke mabaka a mabeli, e ‘ngoe ke “hysteresis loss”‘ me e ‘ngoe ke “eddy current loss”.

Hysteresis tahlehelo ke tahlehelo ea tšepe e bakoang ke hysteresis nakong ea ts’ebetso ea magnetization ea mantlha ea tšepe. Boholo ba tahlehelo ena bo lekana le sebaka se pota-potiloeng ke hysteresis loop ea thepa. The hysteresis loop ea tšepe ea silicon e moqotetsane ebile e nyenyane, ‘me tahlehelo ea hysteresis ea mokokotlo oa tšepe ea transformer e nyenyane, e ka fokotsang mocheso oa mocheso haholo.

Kaha tšepe ea silicon e na le melemo e ka holimo, ke hobane’ng ha u sa sebelise karolo e feletseng ea tšepe ea silicon e le motheo oa tšepe, empa hape u e sebelise ho ba lakane?

Lebaka ke hobane letlapa la tšepe le ka fokotsa mofuta o mong oa tahlehelo ea tšepe – “tahlehelo ea hona joale ea eddy”. Ha transformer e sebetsa, ho na le hona joale ka har’a coil, ‘me matla a khoheli ao e a hlahisang aa fetoha. Phetoho ena e feto-fetohang ea makenete e etsa hore ho be le moea bohareng. Mokelikeli o hlahisoang mokokotlong oa tšepe o potoloha ka sefofane se pota-potileng ho ea ka tsela ea magnetic flux, kahoo e bitsoa eddy current. Litahlehelo tsa hona joale tsa Eddy li boetse li futhumatsa mantlha. E le ho fokotsa tahlehelo ea hona joale ea eddy, mokokotlo oa tšepe oa transformer o kenngoa ka lipampiri tsa tšepe tsa silicon tse sirelelitsoeng ho tloha ho tse ling, e le hore motlakase oa eddy o fete karolong e nyenyane ea sefapano potolohong e moqotetsane le e telele, e le ho eketsa khanyetso. ea tsela ea eddy ea hona joale; ka nako e ts’oanang, silicon ka tšepe ea silicon e etsa The resistivity e eketsehileng ea thepa e boetse e sebetsa ho fokotsa maqhubu a eddy.

Joalo ka mokokotlo oa tšepe oa transformer, lishiti tsa tšepe tse kolobisitsoeng ka serame tse nang le botenya ba 0.35 mm hangata li khethoa. Ho ea ka boholo ba motsoako oa tšepe o hlokahalang, o khaola likotoana tse telele, ebe o kenngoa ka “letsatsi” kapa “molomo” sebopeho. Ha re bua ka mokhoa oa theory, molemong oa ho fokotsa eddy hajoale, ha botenya ba letlapa la tšepe la silicon le le lesesaane le ho fokotsa likhoele tse hahelletsoeng, phello e ba betere.
