HV Transformer ua haujlwm li cas

HV transformer ua haujlwm ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction, qhov twg ib qho kev hloov magnetic teb induces ib tug voltage hla ib co coils. Lub transformer muaj ob coils - thawj kauj thiab theem nrab kauj. Thaum AC voltage yog siv rau lub hauv paus kauj, nws tsim ib tug hloov magnetic teb uas induces ib tug voltage nyob rau hauv lub thib ob kauj. Qhov voltage induced nyob rau hauv lub thib ob kauj yog nyob ntawm qhov ratio ntawm tus xov tooj ntawm lem nyob rau hauv lub thawj thiab thib ob coils.
