Feem ntau sivlub pauv hloovCores feem ntau ua los ntawm Silicon cov ntawv txheeb. Silicon steel yog ib hom steel yog ib hom steel uas muaj silicon (tseem hu ua silicon), thiab nws cov ntsiab lus silicon yog nruab nrab ntawm {}}. 8% thiab 4.8%. Silicon steel siv raws li qhov tseem ceeb ntawm lub transformer vim tias nws yog cov khoom sib nqus nrog muaj zog sib koom tes. Nyob rau hauv lub energized chil, nws tuaj yeem tsim kev sib nqus loj sib nqus kev siv zog, uas tuaj yeem txo qhov loj ntawm tus hloov pauv. Peb paub tias tus hloov pauv tiag tiag ib txwm ua haujlwm nyob rau hauv AC State, thiab lub zog poob yog tsis tsuas yog nyob rau hauv cov tseem ceeb hauv qab magnetization tam sim no. Lub zog poob hauv cov tub ntxhais feem ntau yog hu ua "IRY poob", thiab cov hlau poob yog tshwm sim los ntawm ob qho, ib qho yog "hysteresis poob" thiab lwm qhov yog "eddy poob". Hysteresis poob yog cov hlau poob tshwm sim los ntawm hysteresis tshwm sim thaum lub sij hawm magnetization ntawm cov tub ntxhais. Qhov loj me ntawm qhov kev ploj no yog ib feem ntawm thaj chaw ib puag ncig los ntawm hysteresis loop ntawm cov khoom. Lub hysteresis loop ntawm silicon steel yog nqaim, thiab lub hysteresis poob ntawm cov tub ntxhais ntawm tus transformer yog me me, uas tuaj yeem txo nws cov cua sov. Txij li thaum Silicon Steel muaj cov txiaj ntsig saum toj no, vim li cas tsis siv tag nrho cov khoom silicon tag nrho ua tus hlau tub ntxhais, tab sis ua nws cov ntawv txheeb? Qhov no vim tias cov ntawv hlau tseem ceeb tuaj yeem txo lwm yam hlau poob- "EDDY poob".
Thaum tus hloov pauv ua haujlwm, muaj kev hloov pauv tam sim no hauv cov kauj, thiab sib nqus flux nws generates yog ntawm chav kawm lwm yam. Qhov kev hloov sib nqus tau sib nqus zoo flux tsim cov inducts tam sim no hauv cov tub ntxhais hlau. Qhov uas tsis tau tsim tam sim no hauv cov hlau core kab core voos nyob rau hauv lub dav hlau perpendicular rau cov kev taw qhia ntawm flux, yog li nws yog hu ua Eddy tam sim no.
Eddy tam sim no poob tseem ua rau cov hlau tseem ceeb kom ua kom sov. Txhawm rau txo cov eddy tam sim no ploj, tus hlau core ntawm lub transformer yog stdy tus neeg me me los ntawm ib lub nqaim thiab ntev ntev kom nce cov kev tiv thaiv ntawm eddy tam sim no txoj kev; Nyob rau tib lub sijhawm, cov silicon hauv cov hlau nplaum hauv cov silicon nce kev tiv taus cov khoom siv, uas tseem ua lub luag haujlwm hauv kev txo qis eddy tam sim no.
Rau cov hlau tseem ceeb ntawm cov transformer, {0. 35 hli tuab-know-rolled silicon steel ntawv feem ntau xaiv. Nws yog txiav rau hauv cov ntawv ntev raws li qhov xav tau tseem ceeb, thiab tom qab ntawd overlapped rau hauv "日" "口" "口". Hauv txoj kev tshawb xav, yog tias eddy tam sim no yog kom txo, lub thinner cov ntawv silicon steel yog thiab lub nqaim cov khoom sib txig yog, qhov zoo dua cov nyhuv. Qhov no tsis tsuas yog txo cov eddy tam sim no ploj thiab kub kub nce, tab sis kuj txuag cov khoom ntawm cov ntaub ntawv silicon steel.
Tab sis qhov tseeb, thaum ua cov ntawv sillicon steel, nws tsis yog raws li cov lus uas muaj peev xwm hais txog cov sijhawm ua haujlwm tau zoo thiab txo cov kev ua haujlwm zoo. Yog li ntawd, thaum ua tus transformer core nrog silicon steel los xij, nws yog ib qho tsim nyog kom hnyav qhov pros thiab cons raws li qhov xwm txheej tshwj xeeb thiab xaiv qhov loj me me.
Cov hloov pauv tau ua raws li lub hauv paus ntsiab lus ntawm induction. Muaj ob lub windings nyob rau ntawm lub kaw core kem, ib qho winding ua ntej thiab muaj kev winding thib ob. Thaum lub ntsej muag ua ntej yog ntxias los ntawm AC fais fab muab voltage. Lub tsho cua daj muaj kev hloov pauv tam sim no, thiab lub peev xwm sib nqus tau tsim. Raws li kev nqis tes ua ntawm cov peev xwm sib nqus, ib qho kev sib sib sib nqus ntawm cov hlau nplaum flux yog tsim hauv cov tub ntxhais.
Raws li rau vim li cas nws tuaj yeem txhawb thiab txo voltage? Tom qab ntawd peb yuav tsum tau siv Lenz txoj kev cai lij choj piav qhia tias cov sib nqus flux tsim los ntawm cov induced tam sim no ib txwm yuav hloov ntawm cov sib nqus flux. Thaum tus thawj sib nqus flux nce, lub sib nqus flux tsim los ntawm cov induced tam sim no yog qhov sib txawv ntawm tus nqus flux. Qhov ntawd yog hais, qhov ua rau muaj hlau nplaum flux tsim los ntawm cov hlau nplaum thib ob yog qhov sib txawv ntawm cov khoom sib nqus, yog li cov qib voltage zoo tshwm nyob rau hauv theem ob. Yog li ntawd, cov hlau tseem ceeb yog qhov sib nqus Circuit Court ib feem ntawm transformer.
