Transformer cores xyuas kom muaj kev sib nqus sib nqus ntawm cov windings. Kawm tag nrho txog cov hom transformer core, lawv tsim, thiab lawv ua dab tsi.
Lub transformer core yog ib tug qauv ntawm nyias laminated los xij ntawm ferrous hlau (feem ntau silicon steel) stacked ua ke, uas cov thawj thiab theem nrab windings ntawm lub transformer yog qhwv nyob ib ncig ntawm.
Qhov chaw ntawm lub hauv paus
Lub transformer core yog ib tug qauv ntawm nyias laminated los xij ntawm ferrous hlau (feem ntau silicon steel) stacked ua ke, uas cov thawj thiab theem nrab windings ntawm lub transformer yog qhwv nyob ib ncig ntawm.
Limbs
Hauv qhov piv txwv saum toj no, cov ceg ntawm cov tub ntxhais yog cov ntu ntsug uas cov coils tau tsim nyob ib puag ncig. Cov ceg tawv kuj tuaj yeem nyob rau sab nrauv ntawm cov coils sab nraud nyob rau hauv rooj plaub ntawm qee qhov qauv tsim. Cov ceg tawv ntawm ib qho kev hloov pauv tseem tuaj yeem raug hu ua ob txhais ceg.
Yawg
Lub yoke yog kab rov tav ntawm cov tub ntxhais uas koom nrog cov ceg tawv ua ke. Tus quab thiab ceg ceg tsim ib txoj hauv kev rau cov hlau nplaum sib nqus kom ntws ywj siab.
Muaj nuj nqi ntawm transformer core
Cov tub ntxhais transformer ua kom zoo sib nqus coupling ntawm cov windings, yooj yim rau kev hloov hluav taws xob hluav taws xob los ntawm thawj sab mus rau theem nrab.
Thaum koj muaj ob lub coils ntawm cov hlau ib sab thiab koj hla cov hluav taws xob tam sim no los ntawm ib qho ntawm lawv, ib qho hluav taws xob hluav taws xob yog induced nyob rau hauv lub kauj thib ob, uas tuaj yeem sawv cev los ntawm ob peb kab sib luag nrog cov kev taw qhia emanating los ntawm sab qaum teb mus rau sab qab teb ncej-hu ua kab. ntawm flux. Nrog cov coils ib leeg, txoj hauv kev ntawm cov flux yuav tsis pom thiab qhov ntom ntawm cov flux yuav tsawg.
Ntxiv cov tub ntxhais hlau hauv cov coils tsom thiab nthuav cov flux los ua kom muaj txiaj ntsig zoo ntawm kev hloov pauv ntawm lub zog ntawm thawj mus rau theem nrab. Qhov no yog vim qhov permeability ntawm hlau yog ntau dua li huab cua. Yog tias peb xav txog electromagnetic flux zoo li ib pawg ntawm cov tsheb mus los ntawm ib qho chaw mus rau lwm qhov, qhwv ib lub kauj nyob ib ncig ntawm cov tub ntxhais hlau yog zoo li hloov txoj kev av av nrog txoj kev loj hauv xeev. Nws yog ntau npaum li cas.
Hom ntawm cov khoom tseem ceeb
Qhov ntxov tshaj plaws transformer cores siv cov khoom hlau, txawm li cas los xij, txoj hauv kev tsim ntau xyoo los kho cov hlau ore rau hauv cov ntaub ntawv permeable ntau dua xws li silicon steel, uas yog siv niaj hnub no rau kev tsim cov tub ntxhais transformer vim nws cov permeability ntau dua. Tsis tas li, kev siv ntau daim ntawv qhia txog cov lus qhia ntau ntawm cov teeb meem uas tau txo cov teeb meem los ntawm cov khoom siv hlau tsis muaj zog. Ntxiv qhov nce ntxiv hauv cov qauv tsim yog tsim los ntawm kev sib tw txias, annealing, thiab siv cov nplej oriented steel.
1.Cold Rolling
Silicon hlau yog cov hlau softer. Txias dov silicon steel yuav ua rau nws lub zog ua kom nws ruaj khov dua thaum sib sau cov tub ntxhais thiab cov coils ua ke.
2. Kev sib tw
Cov txheej txheem annealing muaj cua sov cov tub ntxhais hlau mus txog qhov kub thiab txias kom tshem tawm impurities. Cov txheej txheem no yuav ua rau kom softness thiab ductility ntawm cov hlau.
3.Grain Oriented Steel
Silicon steel twb muaj qhov permeability siab heev, tab sis qhov no tuaj yeem nce ntxiv los ntawm kev taw qhia cov nplej ntawm cov hlau hauv tib qho kev taw qhia. Grain oriented steel tuaj yeem ua kom muaj qhov ntom ntom ntawm 30%.
Peb, Plaub, thiab Tsib Limb Cores
Peb Limb Core
Peb limb (los yog ceg) cores feem ntau siv rau kev faib chav kawm qhuav-hom transformers-ob qho tib si qis thiab nruab nrab voltage hom. Peb limb stacked core tsim kuj yog siv rau cov roj puv fais fab chav kawm transformers. Nws tsis tshua pom muaj peb limb tub ntxhais siv rau cov roj ntim cov khoom siv hluav taws xob.
Vim tias tsis muaj ib qho chaw sab nrauv, peb lub legged core ib leeg tsis haum rau wye-wye transformer configurations. Raws li daim duab hauv qab no qhia tau hais tias, tsis muaj txoj hauv kev rov qab mus rau qhov xoom kab ke flux uas muaj nyob rau hauv wye-wye transformer designs. Lub xoom kab ke tam sim no, tsis muaj txoj hauv kev rov qab los txaus, yuav sim tsim txoj hauv kev, xws li siv cov pa tawm los yog lub tank transformer nws tus kheej, uas tuaj yeem ua rau overheating thiab tej zaum transformer tsis ua hauj lwm.
( Kawm paub yuav ua li cas transformers cuam tshuam nrog cua sov los ntawm lawv cov chav kawm txias)
Plaub Limb Core
Tsis yog siv lub faus delta tertiary winding, plaub lub caj dab core tsim muab ib sab sab nraud rau rov qab flux. Hom qauv tsim no zoo ib yam li tsib lub caj dab tsim ib yam nkaus hauv nws cov kev ua haujlwm, uas yuav pab txo qis cua sov thiab ntxiv cov suab nrov ntawm lub tshuab hluav taws xob.
Tsib Limb Core
Tsib-legged wrapped core designs yog tus qauv rau txhua qhov kev faib khoom siv hluav taws xob niaj hnub no (tsis hais seb lub tsev puas yog wye-wye). Txij li qhov chaw hla ntawm peb sab hauv cov ceg ntoo uas nyob ib puag ncig los ntawm cov coils yog ob npaug ntawm qhov loj ntawm peb ceg ceg tsim, qhov chaw hla ntu ntawm tus quab thiab cov ceg sab nraud tuaj yeem yog ib nrab ntawm cov ceg sab hauv. Qhov no pab txuag cov khoom siv thiab txo cov nqi tsim khoom thiab.
