Dab tsi yog Silicon Steel Toroidal Core?
Lub silicon steel toroidal core yog lub nplhaib- zoo li tus tub ntxhais lub qhov txhab los ntawm cov kab nrib pleb ntawm cov nplej- taw qhia silicon steel, feem ntau siv hauv transformers, chokes thiab tam sim no transformers. Cov duab toroid tshem tawm cov pa sib txawv hauv txoj kev sib nqus, muab cov permeability siab, tsis tshua muaj dej inductance, tsis tshua muaj suab nrov thiab kev ua haujlwm siab piv nrog cov stacked EI lossis C cores ntawm qhov sib npaug.
Vim li cas Silicon Steel?
Silicon steel offers high saturation flux density (about 2.0 T), moderate core loss and well-established supply chains, which keeps cost low for power-frequency applications. Grain- cov qhab-nees taw qhia yog nyiam rau toroids vim hais tias cov flux ua raws cov kev taw qhia dov ib ncig ntawm lub nplhaib, ua kom zoo dua ntawm cov khoom sib nqus sib nqus.
Kev tsim khoom
Slitting ntawm grain -oriented kauj mus rau hauv meej strip widths.
Winding lub sawb mus rau ib tug mandrel nyob rau hauv kev tswj nruj nreem tsim lub toroid.
Annealing nyob rau hauv qhov chaw tiv thaiv kom txo tau kev ntxhov siab thiab teeb tsa cov khoom sib nqus.
Txiav lossis gapping qhov twg xav tau qhov sib txawv ntawm huab cua.
Txheej los yog potting nrog kua roj vanish, epoxy los yog cob rau rwb thaiv tsev thiab mechanical stability.
Yam Parameters
| Parameter | Yam nqi |
|---|---|
| Sawb thickness | 0.23-0.35 hli |
| Saturation flux ceev | cav 2,0t |
| Ua tau zoo permeability | ntau txhiab (tsis txiav) |
| Core poob ntawm 1.7 T, 50 Hz | 0.8-1.5 W / kg los ntawm qib |
| Fill factor | 0.92-0.96 |
Daim ntawv thov
Silicon steel toroidal cores yog siv nyob rau hauv lub hwj chim transformers, cais transformers, suab transformers, chokes thiab reactors, tam sim no transformers thiab sib nqus amplifiers qhov twg compact loj thiab tsawg stray teb teeb meem.
Kev xaiv xaiv
Xaiv cov tub ntxhais los ntawm qhov xav tau volt -ampere ntsuas, kev khiav hauj lwm zaus, flux ceev thiab lub voj voog ua haujlwm. Rau DC-biased circuits, qhia qhov gapped core. Paub meej tias cov chav kawm rwb thaiv tsev ntawm cov txheej rau daim ntawv thov kub.
FAQ
Vim li cas toroidal cores ntsiag to dua EI cores?
Txoj kev mob tsis tu ncua tsis muaj pob qij txha, yog li magnetostriction thiab sib koom ua ke kev co yog txo qis, txo cov suab nrov.
Qhov sib txawv ua dab tsi hauv lub toroid?
Txiav qhov sib txawv yuav txo tau cov permeability zoo thiab ua rau DC tam sim no muaj peev xwm ua ntej saturation, ntawm tus nqi ntawm qee qhov inductance thiab ntau dua to.
Puas tuaj yeem toroidal cores tau stacked?
Cov toroids tus kheej tuaj yeem muab sib dhos thiab sib txuas hauv cov koob lossis sib dhos kom nce lub zog tuav, tab sis ib qho tseem ceeb loj dua feem ntau ua haujlwm tau zoo.
Yuav ua li cas yog lub hauv paus qhov txhab nrog hlau?
Vim tias lub nplhaib kaw, winding yog ua tiav nrog lub shuttle lossis toroidal winding tshuab uas hla cov hlau los ntawm qhov chaw nruab nrab.
Dab tsi yog cov qauv siv rau silicon steel sawb?
Cov ntaub ntawv qhia tshwj xeeb suav nrog GB / T 2521, IEC 60404-8-7 thiab ASTM A876 rau kev taw qhia hluav taws xob hlau sawb.
