Engineering cuam tshuam thiab thev naus laus zis kev hloov kho ntawm silicon hlau tuab ntawm transformer kev ua tau zoo
Silicon steel, raws li cov khoom siv tseem ceeb rau transformer Lamations, cuam tshuam cov khoom siv ncaj qha, qhov loj me, thiab tus nqi kav. Qhov kev tsom xam no tshawb txog kev lag luam ntau ntau cov kev lag luam-tawm hauv cov tuab xaiv rau transformer tsim, kev siv tshuab thiab thev naus laus zis.
1. Cov tub ntxhais ploj ua lub cev thiab tuab cuam tshuam
Eddy tam sim no kev poob hauj lwm quadratically nrog lamination tuab. Engineering data show that a {{{{10}}}}.1 mm increase in thickness raises specific losses (W/kg) by ~35% at 1.5 T flux density. Piv txwv li, Hitachi Zog lub 2 0 23 {{{{} {mm}}}} € siv cov khoom siv ntawm 0.30 cov khoom siv. Feem ntau, thaum tuab poob qis dua 0.15 mm, hysteresis poob ntau dua 60% ntawm tag nrho cov kev taw qhia crystal tseem ceeb. Nippon Steel NSGO-TM ua tiav hysteres ua tiav ntawm 0.7 W / 1 T / 50% ntawm 0.10 mm thickness optimization, ze theoretical txwv.
2. Cov Khoom Siv Kev Siv
In 800 V EV platforms, onboard chargers (OBCs) handle 20–100 kHz frequencies. BYD's Seal model uses 0.08 mm amorphous alloy ribbons in its 6.6 kW OBC, achieving 75% lower core losses than 0.15 mm silicon steel at 100 kHz. Delta Electronics' 2024 1 MHz server power modules employ 5 μm nanocrystalline ribbons via chemical vapor deposition (CVD), maintaining permeability >8 {0 00 00 hauv MHZ li. Xws li Ultratin cov ntaub ntawv yuav tsum tau ua cov tshiab-piv txwv, AT & M cov thev naus laus zis ua rau muaj 30 μm amorphous strips nrog ± 0.2 μm winding precision.
3. Kev tsim kho cov ntsiab lus rau kev sib nqus
Tesla's 4-gen tsav tsav chaw nyob cov chaw muaj kev sib tw dawb huv hauv cov lamination nyias muaj peb lub tswv yim:
{{{{0} d hlau nplaum ntawm kev tsim: laser-etch}. 05 hli
- Gradient Annealing: Hydrogen-ann atm ann annealING (1200 DEGREE) txo analaling (750 degree) khaws cia siab tshaj plaws ntawm lub core Center
- Dynamic kev tsis sib koom zog tswj: Lub sijhawm aws kev hloov kho igbt kho kom muaj kev ua haujlwm ntawm BH Nkhaus lub hauv caug
Qhov no ua rau cov qauv qauv Q tus tub ntxhais xyaum ua haujlwm linearly ntawm 2.2 t pe flux ntom ntom, ua tiav 6.8 kg lub zog.
4. Txiav cov khoom siv ntoo
- Hybrid rwb thaiv tsev: Toshiba lub sio₂ / al₂o₃ dual-txheej C5 txheej (2 μ00
- Topology-optimized cov qauv: ABB lub wavy Lamination Tsim (Wo2 0. 25 hli thickness ntawm 0.10 hli
- Hydrogen Metallgy: Baubuu Group Hydrogen-based txo cov txheej txheem kev txo qis ncaj qha tsim cov roj caricon (C) (C00}
5. Cov kev hloov pauv thiab kev lag luam kev ua lag luam
The updated IEC 60404-8-7:2023 standard introduces S10-S18 loss grades, with S14 (≤0.95 W/kg at 0.20 mm/50 Hz/1.7 T) becoming mandatory for EU market entry. TBEA's QQ23 material achieves 0.89 W/kg at 0.23 mm, surpassing China's 2025 national standard three years early. This technological leap is reshaping global supply chains-JFE Steel has shut three lines producing >{{{{{{0}}}}. 30 hli hlau los nthuav nws 0.10 hli nanocrystalline cog hauv Hiroshima.
