Cov ntaub ntawv hloov pauv feem ntau poob rau hauv peb pawg: cov ntaub ntawv tseem ceeb, cov khoom siv winding, thiab cov ntaub ntawv rwb thaiv tsev thiab cov khoom cua txias; txhua qhov cuam tshuam ncaj qha cuam tshuam rau transformer kev ua tau zoo thiab kev pabcuam lub neej.
Transformer cores feem ntau yog ua los ntawm silicon steel los xij. Cov khoom siv no muaj qhov sib nqus permeability siab, txhim khu kev sib nqus flux conduction thaum txo qis hysteresis thiab eddy tam sim no poob. Hauv qee qhov siab - zaus lossis kev siv tshwj xeeb, amorphous alloys yog siv los txo cov tub ntxhais poob thiab txhim kho kev ua haujlwm.
Windings feem ntau siv tooj liab lossis txhuas. tooj liab yog nyiam rau loj - muaj peev xwm los yog siab - kev ntseeg siab transformers vim nws superior hluav taws xob conductivity thiab mechanical zog, whereas aluminium- raug nqi ntau dua - siv tau thiab lub teeb yuag - feem ntau yog siv nyob rau hauv me me - mus rau nruab nrab - cov khoom loj. Rwb thaiv tsev feem ntau yog siv cov ntawv insulating, insulating kua roj vanish, lossis epoxy resin; roj-immersed transformers, lub sijhawm no, ntiav cov roj hloov pauv, uas ua haujlwm rau ob lub hom phiaj ntawm kev muab rwb thaiv tsev thiab ua kom yooj yim rau cua sov dissipation thiab txias.
