Qhuav- hom transformers ua tiav qhov kev hloov pauv ntawm qhov hluav taws xob sab nraud (siab-} sab hluav taws xob) thiab sab tso zis (tsawg-voltage sab) los ntawm kev sib nrig sib inductance, tsis tas yuav tsum muaj cov kua nruab nrab insulating. Lawv lub ntsiab haujlwm tseem ceeb suav nrog:
Lub siab -voltage side coil generates ib magnetic teb, uas induces ib tug electromotive quab yuam nyob rau hauv qis -voltage sab coil.
Los ntawm electromagnetic induction, lub teeb liab input voltage yog hloov dua siab tshiab rau hauv qhov xav tau tso zis voltage.
Qhuav- hom transformers siv cua lossis lwm yam khoom siv qhuav rau kev rwb thaiv tsev, yog li zam kev nyab xeeb xws li cov roj to thiab tawg uas yuav muaj nyob hauv cov roj-immersed transformers, txhim kho kev ntseeg siab thiab kev nyab xeeb ntawm cov khoom siv.
