High Permeability Nanocrystalline C core
Nanocrystalline cov ntaub ntawv kuj muaj qhov zoo ntawm silicon steel, permalloy, thiab ferrite.uas yog:
1. High sib nqus induction: saturation magnetic induction Bs = 1.2T, uas yog ob zaug ntawm permalloy thiab 2.5 npaug ntawm ferrite.Lub zog ceev ntawm cov tub ntxhais hlau yog loj, uas tuaj yeem ncav cuag 15 kW txog 20 kW / kg.
2. High permeability: Thawj qhov zoo li qub permeability μ0 tuaj yeem siab li 120,000 txog 140,000, uas yog sib npaug permalloy.Qhov sib nqus permeability ntawm cov tub ntxhais hlau ntawm lub zog hloov hluav taws xob yog ntau dua 10 npaug ntawm cov ferrite, uas ua rau kom lub zog excitation thiab txhim kho kev ua haujlwm ntawm lub transformer.
3. Kev poob qis: nyob rau hauv ntau zaus ntawm 20kHz txog 50kHz, nws yog 1/2 txog 1/5 ntawm ferrite, uas txo qhov kub ntawm cov tub ntxhais hlau.
4. High Curie kub: Curie kub ntawm nanocrystalline cov ntaub ntawv mus txog 570 ℃, thiab Curie kub ntawm ferrite tsuas yog 180 ℃ ~ 200 ℃.
Vim qhov zoo li saum toj no, lub transformer ua los ntawm nanocrystals yog siv nyob rau hauv lub inverter fais fab mov, uas tau ua lub luag hauj lwm zoo nyob rau hauv kev txhim kho kev ntseeg siab ntawm lub hwj chim mov:
1. Qhov poob yog me me thiab qhov kub thiab txias ntawm transformer yog tsawg.Kev siv lub sijhawm ntev ntawm ntau tus neeg siv tau ua pov thawj tias qhov kub thiab txias ntawm nanocrystalline transformer yog qis dua li ntawm IGBT raj.
2. Lub siab sib nqus permeability ntawm cov tub ntxhais hlau yuav txo tau lub zog excitation, txo cov tooj liab poob, thiab txhim kho kev ua tau zoo ntawm cov transformer.Thawj inductance ntawm lub transformer yog loj, uas txo qhov cuam tshuam ntawm tam sim no ntawm IGBT raj thaum hloov.
3. Kev ua haujlwm sib nqus induction yog siab thiab lub zog ceev yog siab, uas tuaj yeem ncav cuag 15Kw / kg.Lub ntim ntawm cov tub ntxhais hlau yog txo.Tshwj xeeb tshaj yog cov high-power inverter fais fab mov, qhov ntim yuav txo tau qhov chaw nyob rau hauv lub chassis, uas yog zoo rau lub tshav kub dissipation ntawm lub IGBT raj.
4. Lub peev xwm overload ntawm lub transformer muaj zog.Txij li thaum ua haujlwm sib nqus inductance raug xaiv ntawm kwv yees li 40% ntawm qhov saturation sib nqus inductance, thaum lub overload tshwm sim, lub tshav kub tsuas yog tsim los ntawm kev nce ntawm cov hlau nplaum inductance, thiab IGBT raj yuav tsis puas vim qhov saturation ntawm cov hlau nplaum inductance. cov tub ntxhais hlau.
5. Curie kub ntawm nanocrystalline cov ntaub ntawv yog siab.Yog tias qhov kub siab tshaj 100 ° C, lub ferrite transformer tsis tuaj yeem ua haujlwm, thiab nanocrystalline transformer tuaj yeem ua haujlwm ib txwm.
Cov txiaj ntsig zoo ntawm nanocrystalline no tau lees paub thiab tau txais los ntawm cov tuam txhab hluav taws xob ntau thiab ntau dua.Ib tug xov tooj ntawm domestic manufacturers tau txais nanocrystalline hlau cores thiab siv tau rau ntau xyoo.Ntau thiab ntau manufacturers pib siv los yog sim nws.Tam sim no, nws tau siv dav hauv inverter vuam tshuab, kev sib txuas lus fais fab mov, electroplating thiab electrolytic fais fab mov, induction cua sov fais fab mov, them fais fab mov thiab lwm yam kev lag luam, thiab yuav muaj ntau dua nyob rau hauv ob peb xyoos tom ntej no.
