Lub Transformer tuaj yeem nce qhov voltage
Lub transformer yog ib yam khoom siv los hloov hluav taws xob hluav taws xob los ntawm ib lub voj voog mus rau lwm qhov los ntawm txoj cai ntawm electromagnetic induction. Feem ntau, transformers yog siv los nce lossis txo qhov voltage hauv AC circuits. Tab sis, lo lus nug yog, lub transformer puas tuaj yeem nce voltage? Cov lus teb yog ib qho tseem ceeb YES!
Lub transformer tuaj yeem nce qhov voltage los ntawm kev siv lub hauv paus ntsiab lus ntawm electromagnetic induction. Nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm Faraday txoj cai ntawm electromagnetic induction. Thaum lub AC tam sim no ntws los ntawm thawj kauj ntawm lub transformer, nws tsim ib tug hloov magnetic flux. Qhov no hloov magnetic flux ces induces ib tug voltage nyob rau hauv lub thib ob kauj. Tus nqi ntawm qhov voltage induced nyob rau hauv lub thib ob kauj yog proportional rau tus naj npawb ntawm lem nyob rau hauv lub thib ob kauj thiab tus nqi ntawm cov sib nqus flux.
Yog hais tias tus naj npawb ntawm cov lem nyob rau hauv lub thib ob kauj yog ntau tshaj li tus naj npawb ntawm lem nyob rau hauv thawj kauj, qhov voltage nyob rau hauv lub thib ob kauj yuav ntau dua qhov voltage nyob rau hauv thawj kauj. Yog li ntawd, ib tug transformer yuav ua rau kom voltage. Tus nqi ntawm qhov nce voltage nyob ntawm qhov sib piv ntawm tus naj npawb ntawm cov lem nyob rau hauv lub thib ob kauj mus rau tus naj npawb ntawm lem nyob rau hauv thawj kauj. Qhov no yog hu ua tus lem ratio.
Transformers muaj ntau yam kev siv, los ntawm cov tshuab hluav taws xob xa mus rau cov khoom siv hluav taws xob. Lawv ua lub luag haujlwm tseem ceeb hauv cov tshuab hluav taws xob niaj hnub. Los ntawm kev ua kom muaj zog, cov khoom siv hluav taws xob tuaj yeem xa hluav taws xob tau zoo nyob rau hauv qhov ntev, txo cov hluav taws xob poob, thiab muab lub zog muaj kev nyab xeeb thiab yooj yim dua rau cov tsev thiab cov lag luam.
Hauv kev xaus, lub tshuab hluav taws xob tuaj yeem nce qhov voltage los ntawm kev siv lub hauv paus ntsiab lus ntawm electromagnetic induction. Qhov no tso cai rau kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig ntawm kev xa hluav taws xob hluav taws xob, ua rau nws yog ib qho tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub. Yog li ntawd, transformers tsis yog tsuas yog ib qho txuj ci tseem ceeb ntawm kev tshawb fawb thiab thev naus laus zis tab sis kuj yog ib feem tseem ceeb ntawm peb lub neej niaj hnub.
