Yuav Ua Li Cas Ib Kauj Ruam Down Transformer Ua Haujlwm?

Lub hauv paus ntsiab lus ua haujlwm ntawm step down transformer

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub transformer yog "Faraday txoj cai ntawm electromagnetic induction", uas yog, "thaum lub sib nqus flux txuas nrog lub Circuit Court hloov, lub electromotive quab yuam induced nyob rau hauv lub Circuit Court yog proportional rau tus nqi ntawm kev hloov ntawm magnetic flux". Qhov kev xa tawm hauv lub transformer yog ua los ntawm kev sib nrig sib induction ntawm cov windings. Tus naj npawb ntawm cov lem ntawm thawj winding thiab lub thib ob winding feem txiav txim siab lub electromotive quab yuam induced ntawm ob lub windings, thiab qhov piv no yog hu ua qhov sib piv. Tab sis koj puas paub dab tsi txiav txim siab lub kauj ruam ntawm transformer lub kauj ruam-down muaj peev xwm? Nws nyob ntawm qhov sib piv ntawm thawj thiab theem nrab coils. Qhov sib nqus flux nyob rau hauv lub transformer theem nrab kauj yog tseem tsawg dua piv rau cov thawj kauj vim hais tias cov xov tooj ntawm windings nyob rau hauv lub thib ob kauj kuj tseem tsawg tshaj li cov windings nyob rau hauv thawj kauj. Yog li ntawd, EMF induced nyob rau hauv lub thib ob kauj yuav me me, uas thaum kawg txo qhov voltage ntawm lub thib ob winding, es tsis yog thawj winding.

Ns/Np=Vs/Vp

Ns=Tus naj npawb ntawm qhov hloov pauv thib ob

Np=Tus naj npawb ntawm qhov pib winding

Vs =thib ob winding voltage

Vp= thawj winding voltage

But remember, for the transformer to work as a "step-down transformer", the number of turns in the secondary winding must always be less than the number of turns in the primary winding of the transformer, ie Np>Ns.
