1.Vim li cas cov khaub thuas zoo tib yam -rolled coils tsis haum?
Tsis tshua muaj resistivity ua rau siab heev eddy tam sim no poob.
Miniature transformers feem ntau ua haujlwm ntawm cov zaus siab (piv txwv li, kHz rau MHz qib hauv kev hloov khoom siv hluav taws xob).
Tej yam txias-rolled steel yog ib tug zoo conductor nrog tsawg resistivity. Nyob rau hauv siab - zaus alternating magnetic teb, cov eddy tam sim no loj yog tsim nyob rau hauv cov tub ntxhais, ua rau cua kub hnyav, tsis tshua muaj efficiency, thiab txawm inoperability.
Tsis muaj optimized magnetic zog.
Siab coercivity: Magnetization thiab demagnetization yog qhov nyuaj, ua rau muaj kev poob siab ntau.
Tsawg permeability: Yuav tsum muaj qhov muaj zog sib nqus hlau nplaum kom ua tiav qhov xav tau sib nqus flux ntom ntom, uas ua rau kom muaj zog tam sim no thiab tooj liab poob.
Sib nqus saturation induction: Txawm hais tias qhov saturation point ntawm txias- dov steel tsis qis, vim hais tias ob qho kev poob loj, kev ua haujlwm tau qis dua thiab cov cua kub hnyav tshwm sim ua ntej saturation mus txog.
2.Dab tsi cov ntaub ntawv yuav tsum tau siv rau lub hauv paus ntawm ib tug me me transformer?
Hluav taws xob hlau, tshwj xeeb tsim rau cov ntawv thov electromagnetic, tseem hu ua silicon steel los yog electromagnetic steel daim hlau, yog qhov kev xaiv raug. Cov no feem ntau muab faib ua ob pawg: txias- dov tsis yog-qhia silicon steel thiab txias- dov oriented silicon steel.
3.Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev siv ferrite hauv me me transformers?
Qhov no tam sim no yog cov khoom siv tseem ceeb tshaj plaws thiab kev lag luam tseem ceeb rau cov khoom me me siab - zaus transformers.
Nws yog cov khoom siv ceramic uas muaj kev tiv thaiv siab heev, yuav luag tag nrho tshem tawm eddy tam sim no poob, thiab yog tsim tshwj xeeb rau cov zaus ntawm kHz mus rau MHz.
Disadvantages: It has a relatively low saturation magnetic flux density (approximately 0.5T), making it unsuitable for high-power or low-frequency (power frequency) applications.
4.Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev siv amorphous thiab nanocrystalline alloys hauv micro transformers?
High - kev xaiv ua tau zoo. Nws muaj cov permeability siab heev, tsis tshua muaj coercivity, thiab tsis tshua muaj hlau poob.
Nanocrystalline ntau yam, tshwj xeeb tshaj yog, nthuav tawm kev ua tau zoo thoob plaws ntau qhov ntau zaus (los ntawm kaum ntawm Hz mus rau ntau pua kHz) thiab feem ntau yog siv rau hauv siab -kawg micro-transformers (xws li lub zog tshiab thiab siab - kawg cov khoom siv hluav taws xob) qhov kev ua tau zoo, qhov loj me, thiab qhov ntsuas kub nce siab yuav tsum nruj.
Disadvantages: Tus nqi siab, siab brittleness, thiab tseem ceeb ua nyuaj.
5.Dab tsi yog txoj hauv kev zoo rau kev xaiv cov khoom siv?
Txiav txim siab qhov ua haujlwm zaus thiab lub zog.
Xaiv cov khoom siv raws li qhov zaus:
Fais fab zaus (50/60Hz): Siv cov ntawv silicon steel (unoriented lossis oriented).
Nruab nrab-siab zaus (kHz - pua kHz): Ferrite nyiam dua.
Siab -kev ua tau zoo broadband lossis tshwj xeeb yuav tsum tau: Xav txog amorphous/nanocrystalline alloys.
