Ib lub transformer yog lub cuab yeej uas nce lossis txo voltage.Qhov no ua haujlwmlub ntsiab lusNtawm lub transformer yog cov khoom hluav taws xob zoo li qub uas tau sib pauv portrage lossis tam sim no ntawm ob lossis ntau cov windings ntawm tib zaus hluav taws xob los ntawm kev ntsuas hluav taws xob. Uas yog, nws txoj cai ua hauj lwm yog"Hluav Taws Xob Ua General Generates Magnetism, Hlauletism Tsim Hluav Taws Xob".

Tus ua haujlwm ua haujlwm ntawm cov hloov pauv yog hluav taws xob induction, tab sis nruj me ntsis kev hais lus, nws yog vim kev sib nrig sib hais lus tsis meej. Cov hauv qab no yog kev piav qhia ntawm txoj cai induction thiab kev sib nrig sib tham induction ua:

Lub hauv paus ntsiab lus ntawm indectromagnetic induction:Thaum lub sib nqus flux txuam nrog kev hloov pauv coil (lossis peb tuaj yeem nkag siab tias lub zog hluav taws xob ( Nov yog qhov kev piav qhia zoo tshaj plaws ntawm "hluav taws xob hluav taws xob".

Tshwj xeeb, raws li kev sib tw induction lub hauv paus, qhov tam sim no ua rau lub zog hluav taws xob (tsis muaj qhov sib tw ntawm kev hloov pauv ntawm flux sib nqus dhau los ntawm cov kauj. Peb tuaj yeem piav qhia cov lus no ntau intuitively hauv kev ua lej,, where e yog qhov ua rau lub zog hluav taws xob, n yog tus naj npawb ntawm lem ntawm lub kauj, thiabyog tus nqi ntawm kev hloov ntawm cov sib nqus flux.

Cia peb saib kev sib nrig sib:Qhov hloov pauv hloov tam sim no hauv thawj kauj kav tsim kev hloov sib xyaw sib nqus hauv cov kauj hauv theem nrab, thiab hloov cov hlau sib nqus hauv cov kauj hauv theem nrab, uas yog qhov tsis tam sim no: EMF. Kev sib nrig sib cai yog qhov txiaj ntsig ncaj qha ntawm Faraday Txoj Cai.

Transformers yog qhov piv txwv zoo tshaj plaws ntawm kev sib nrig sib, thiab peb txhais tau tias yog qhov txuas ntxiv ntawm lub zog hluav taws xob (tam sim no muaj kev hloov pauv ntawm kev sib khi (uas yog qhov peb hu tau"Hluav Taws Xob Ua General Generates Magnetism, Hlauletism Tsim Hluav Taws Xob").

Hauv kev nthuav dav, kev tsim tawm Lenz txoj cai lij choj, tam sim no los ntawm kev sib nrig sib cuam tshuam ntawm ob coils (m) Kev sib nrig sib los ntawm ob coils yog tib yam..

Raws li txoj haujlwm, cov hloov pauv tuaj yeem faib ua kauj ruam {{0} {} {} {} {ice down ntawm ob hom kev hloov pauv.

Ntev - deb hluav taws xob sib tsoo:Thaum peb xav nqa tawm ntev - deb faiv fab kis tau tam sim no nyob rau hauv cov nqe lus ntawm tus nqi {}} ua hauj lwm zoo thiab ua haujlwm. Yog li ntawd, peb feem ntau tsis txhob siv qis qis- volthage tam sim no tsis yog tsuas yog qeeb} Kev deb} Deb rau ib cheeb tsam yog ntau dua.

Txhawm rau kom zam dhau qhov xwm txheej saum toj no, peb ib txwm siv fais fab hloov hluav taws xob ib lub sijhawm, yog li txo lub zog los ntawm kev tawm tsam thaum kis tau.

Los ntawm kev siv kauj ruam - Up transformers (Nyem txhawm rau paub txog kauj ruam - Up Transformers), Peb tuaj yeem hloov hluav taws xob tau zoo los ntawm cov fais fab fais fab ntawm cov nroj tsuag rau cov khoom siv hluav taws xob nyob deb ntawm cov khoom siv hluav taws xob nyob deb ntawm cov khoom siv hluav taws xob nyob deb ntawm cov khoom siv hluav taws xob nyob deb ntawm cov khoom siv hluav taws xob nyob deb ntawm cov khoom siv hluav taws xob nyob deb ntawm cov khoom siv hluav taws xob nyob deb ntawm cov khoom siv fais fab. (Hais txog qhov teeb meem ntawm enameled copper hlau thiab enameled txhuas hlau, Yawg Txhuas Txhuas kuj tseem ntseeg tau.)

Haum rau load uas yuav tsum tau:Cov khoom siv hluav taws xob sib txawv thiab tshuab muaj kev sib txawv voltage yuav tsum muaj. Lub zog hloov hluav taws xob tuaj yeem hloov siab dua- voltage hluav taws xob hauv qis- voltage hluav taws xob (Kauj Ruam -} down transformers) Tsim nyog rau cov cuab yeej tshwj xeeb lossis cov tshuab los xyuas kom muaj kev ua haujlwm ib txwm ntawm cov khoom siv. Piv txwv li, qis {{{- voltage cov khoom siv thiab siab} {} {voltage Poles yog ib feem ntawm lub zog hluav taws xob. Vim kev sib kis, lawv cov khoom siv hluav taws xob siab dua li cov cuab yeej hluav taws xob txhua hnub, tab sis peb cov khoom siv hluav taws xob txhua hnub, yog li cov khoom siv hluav taws xob txhua hnub, yog li tam sim no yuav tsum tau nqis.

Hu rau tam sim no
