B27R080 0.27mm Grain-Oriented Electrical Steel

 

B27R080 yog 0.27 hli tuab lis- taw qhia hluav taws xob hlau (GOES) qib tsim los ntawm Baosteel (Baowu Steel), belongs rau laser-scripted, domain-refined (magnetic domain refinement) tsev neeg ntawm siab -permeability oriented silicon steels.Nws yog tsim tshwj xeeb rau kev ua haujlwm siab -kev ua tau zoo transformer cores, qhov twg nws tau lees paub qhov siab tshaj plaws ntawm tag nrho qhov poob ntawm 0.80 W / kg ntawm 1.7 T / 50 Hz (P1.7 / 50) thiab qhov sib nqus polarization yam tsawg kawg nkaus ntawm 1.89 T ntawm 800 A / m (B8) xa tuaj yeem ntsuas tau los ntawm 0.0 mm thiab qis dua 0. 0.35mm qib.

 

 

Kev xaiv qib nws tus kheej yog ib qho kev qhia tshwj xeeb:

• B- Baosteel / Baowu Steel, Tuam Tshoj tus tsim khoom loj tshaj plaws ntawm cov nplej- taw qhia hluav taws xob hlau
• 27- nominal strip thickness, 0.27 hli
• R- magnetic domain refined (laser-scribed) hom, ib qho kev txhim kho ntxiv ntawm high -permeability (Hi-B) khoom kab
• 080- lav qhov siab tshaj qhov poob tag nrho ntawm 0.80 W / kg ntsuas ntawm 1.7 T, 50 Hz (P1.7/50)

 

Vim tias qhov poob ntawm qhov tseem ceeb yog qhov tseem ceeb ntawm lub tshuab hloov pauv tsis muaj -load poob, qhov qis - tus yam ntxwv poob ntawm B27R080 ncaj qha txhais mus rau hauv qis zog noj tshaj cov khoom siv tag nrho lub neej. Qhov no ua rau qib tus qauv xaiv rau lub zog-kev ua tau zoo-tsim transformer tsim, suav nrog kev faib cov khoom siv hluav taws xob tsim los rau lub zog tshiab- cov cai tswj kev ua tau zoo, fais fab transformers, reactors, ntsuas transformers, thiab tauj dua tshiab -zog theem- nce transformers.

1. Fais fab transformers

Thawj daim ntawv thov. B27R080 tau teev tseg rau kev faib cov transformer cores tsom rau lub zog ua tau zoo tshaj plaws - qib kev ua tau zoo ib GB 20052-2020 (Tuam Tshoj), DOE 2016 (US) thiab Ecodesign (EU) cov cai tswj kev ua haujlwm zoo. Nws qhov qis P1.7/50 txo qhov tsis muaj kev thauj khoom, uas ua rau tus nqi ntawm lub neej ntawm lub teeb hloov pauv hloov pauv.

 

2. Fais fab transformers

Siv nyob rau hauv nruab nrab thiab loj fais fab transformer cores qhov twg core poob guarantees thiab suab nrov theem yog contractual. Lub npe-refined microstructure kuj txhim kho kev coj tus cwj pwm magnetostriction, txhawb qis suab nrov - qhov tseem ceeb hauv nroog substations.

 

3. Rov ua dua tshiab - kauj ruam zog - nce transformers

Nrog rau kev tsim sai sai- tawm ntawm photovoltaic thiab cua fais fab nroj tsuag, lub thawv- hom (prefabricated) kauj ruam- nce transformers yog cov ceev tshaj - daim ntawv thov GOES loj hlob. B27R080 kev sib xyaw ua ke ntawm qhov poob qis thiab siab sib nqus polarization tso cai rau cov tub ntxhais me me hla-section thiab sib dua, ntau compact transformer tsim - ncaj qha cuam tshuam rau lub thawv ntim / thawv- hom substations dav siv nyob rau hauv hnub ci thiab chaw nres tsheb fais fab.

 

4. Reactors, ntsuas transformers thiab cov cuab yeej tshwj xeeb

B27R080 kuj yog siv rau cov cores ntawm reactors, tam sim no thiab voltage transformers, thiab cov electromagnetic cores ntawm loj industrial drives thiab UPS systems, qhov twg cov khoom sib nqus zoo sib xws thiab tsis tshua muaj siab tam sim no.

 

 

Domain-cov qib ua kom zoo xws li B27R080 xav tau kev tswj xyuas tshwj xeeb, feem ntau vim tias qhov qis- tsis ua haujlwm nyob ntawm lub laser-cov ntawv sau npe siv ntawm lub zeb:

 

Tsis txhob ntxhov siab -kev kho mob tom qab ua tiav.

Kev ntxhov siab-relief annealing (feem ntau 780-830℃rau cov pa GOES) recrystallises saum npoo thiabrhuav tshem lub laser - sau npe - cov nyhuv ua kom zoo, uas tuaj yeem ua rau cov tub ntxhais poob los ntawm ob peb feem pua. Yog hais tias annealing yog unavoidable rau ib tug tshwj xeeb kev tsim kho, tham txog kev ua tiav txoj kev nrog tus neeg muag khoom ua ntej - ib co qhov txhab -core designs txhob txwm siv tsis yog- sau Hi- qib B hloov.

 

Tswj kev txiav thiab stacking kev ntxhov siab.

Shearing, xuas nrig ntaus thiab tuav qhia txhua yam kev ntxhov siab ntawm cov npoo npoo. Siv cov cuab yeej ntse, txo qis qhov siab (tsawg dua lossis sib npaug li 0.025 hli), thiab tsis txhob khoov lossis kinking lub strip.

 

Khaws cov txheej txheem kom zoo.

S- hom txheej muab rwb thaiv tsev ntawm laminations; khawb, xeb los yog paug txo inter-lamination tsis kam thiab ua kom cov dej ntws hauv zos.

 

Khaws kom raug.

Khaws cov coils kom qhuav thiab tiv thaiv. Condensation los yog ntev - lub sij hawm high humidity tuaj yeem txhawb cov ntug xeb, uas nyuaj rau tshem tawm yam tsis ua rau cov txheej txheem puas.

 

Tsim rau kev ua haujlwm flux ceev.

B27R080 yog tsim los ua lag luam kev lag luam hauv 1.65-1.75 T ntau ntawm 50 Hz. Kev khiav hauj lwm dhau ntawm lub hauv caug ntawm magnetisation nkhaus ua rau muaj kev txaus siab tam sim no thiab suab nrov nrov.
