Transformer yog cov cuab yeej siv hluav taws xob induction txoj cai los hloov AC voltage.Nws cov khoom tseem ceeb muaj xws li thawj kauj, theem nrab coil thiab cov tub ntxhais hlau.
Hauv kev ua haujlwm hauv hluav taws xob, feem ntau koj tuaj yeem pom cov duab ntxoov ntxoo ntawm lub transformer, feem ntau yog siv rau hauv cov khoom siv hluav taws xob raws li kev hloov hluav taws xob, kev sib cais.
Nyob rau hauv luv luv, qhov voltage piv ntawm lub hauv paus thiab theem nrab coils yog sib npaug zos rau cov lem ratio ntawm cov thawj thiab thib ob coils.Yog li ntawd, yog tias koj xav tawm qhov sib txawv voltages, koj tuaj yeem hloov qhov sib piv ntawm cov coils.
Raws li qhov sib txawv ua haujlwm zaus ntawm transformers, feem ntau lawv tuaj yeem muab faib ua cov tshuab hluav taws xob tsawg thiab cov tshuab hluav taws xob siab.Piv txwv li, nyob rau hauv lub neej niaj hnub, zaus ntawm lub hwj chim zaus alternating tam sim no yog 50Hz.Peb hu rau transformers ua hauj lwm ntawm no zaus low-frequency transformers;Kev ua haujlwm zaus ntawm high-frequency transformer tuaj yeem ncav cuag kaum ntawm kHz mus rau ntau pua kHz.
Qhov ntim ntawm high-frequency transformer yog ntau me dua li ntawm low-frequency transformer nrog tib lub zog tso zis
Lub transformer yog ib qho tseem ceeb ntawm lub hwj chim Circuit Court.Yog tias koj xav ua kom lub ntim me me thaum ua kom lub zog tso zis, koj yuav tsum siv lub tshuab hluav taws xob siab.Yog li ntawd, high-frequency transformers yog siv nyob rau hauv switching fais fab mov.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm high zaus transformer thiab tsawg zaus transformer yog tib yam, ob qho tib si yog raws li lub hauv paus ntsiab lus ntawm electromagnetic induction.Txawm li cas los xij, hais txog cov khoom siv, lawv "cores" siv cov khoom sib txawv.
Cov tub ntxhais hlau ntawm qhov tsawg zaus transformer feem ntau yog stacked nrog ntau silicon steel los xij, thaum cov tub ntxhais hlau ntawm high-frequency transformer yog tsim los ntawm high-frequency magnetic cov ntaub ntawv (xws li ferrite).(Yog li ntawd, cov tub ntxhais hlau ntawm high-frequency transformer feem ntau hu ua magnetic core)
Hauv DC stabilized voltage fais fab mov Circuit Court, low-frequency transformer transmits sine wave signal.
Nyob rau hauv switching fais fab mov Circuit Court, high-frequency transformer transmits high-frequency mem tes square wave teeb liab.
Ntawm lub zog ntsuas, qhov sib piv ntawm cov zis hluav taws xob thiab lub zog nkag ntawm lub tshuab hloov pauv yog hu ua kev ua haujlwm ntawm lub tshuab hloov pauv.Thaum lub zog tso zis ntawm lub transformer yog sib npaug rau lub zog input, qhov ua tau zoo yog 100%.Nyob rau hauv qhov tseeb, xws li ib tug transformer tsis muaj, vim hais tias cov tooj liab poob thiab hlau poob, lub transformer yuav muaj tej yam poob.
Kev poob tooj liab yog dab tsi?
Vim hais tias lub transformer kauj muaj ib qho kev tiv thaiv, thaum tam sim no dhau los ntawm lub kauj, ib feem ntawm lub zog yuav dhau los ua cua sov.Vim hais tias lub transformer kauj yog mob nrog tooj liab hlau, qhov poob no kuj hu ua tooj liab poob.
Hlau poob yog dab tsi?
Cov hlau poob ntawm transformer feem ntau suav nrog ob yam: hysteresis poob thiab eddy tam sim no poob;Hysteresis poob yog hais txog tias thaum hloov pauv tam sim no dhau los ntawm lub kauj, cov kab sib nqus ntawm lub zog yuav raug tsim kom dhau los ntawm cov tub ntxhais hlau, thiab cov molecules hauv cov tub ntxhais hlau yuav rub tawm ib leeg los ua kom muaj cua sov, yog li siv ib feem ntawm lub zog hluav taws xob;Vim tias cov kab sib nqus ntawm lub zog dhau los ntawm cov tub ntxhais hlau, cov tub ntxhais hlau kuj tseem yuav tsim kom muaj kev cuam tshuam tam sim no.Vim tias qhov tam sim no yog swirling, nws tseem hu ua eddy tam sim no, thiab eddy tam sim no poob kuj yuav siv qee lub zog hluav taws xob.
