Dab tsi yog Amorphous Alloy Transformer Core?
Amorphous alloy yog cov khoom siv hlau nplaum tshiab uas tsim los ntawm kev sib zog sai ntawm cov hlau molten ntawm qhov txias ntawm ib lab degrees Celsius ib ob. Vim hais tias cov atoms tsis muaj sij hawm los tsim ib tug siv lead ua lattice, lub resulting ribbon muaj ib tug iav -zoo li amorphous qauv uas muab nws zoo heev mos magnetic zog. Nws yog dav lees paub tias yog ib puag ncig tus phooj ywg, lub zog - txuag thiab siab - cov khoom siv tau zoo.
Amorphous ribbon tuaj yeem raug mob rau hauv cores rau EMC hom inductors, tam sim no transformer cores, fais fab transformer cores thiab inductor cores. Nws qhov zoo muaj xws li siab permeability, siab saturation induction, siab hluav taws xob resistivity, siab ceev, tsis tshua muaj tub ntxhais poob thiab zoo stability, cia nws hloov silicon steel, permalloy thiab ferrite nyob rau hauv ntau lub hwj chim thiab hluav taws xob siv.
Cov yam ntxwv tseem ceeb ntawm Amorphous Cores
High saturation magnetic induction nrog muaj zog tiv thaiv -saturation muaj peev xwm, ua ke nrog siab sib nqus permeability, tsis tshua muaj coercivity thiab tsawg poob.
Zoo kub stability, ua haujlwm ruaj khov ntawm -25℃mus rau 100 degree.
Zoo overload tsis kam, lav lub sijhawm ntev - ua haujlwm ruaj khov.
rhiab heev rau tsis muaj zog to tam sim no, nrog zoo kuj rau loj tam sim no cuam tshuam.
Core nto tiv thaiv technology uas tiv thaiv cov tub ntxhais khib nyiab thiab ntug kev puas tsuaj.
Vim li cas Amorphous Cores Txiav Transformer Losses
Qhov txiaj ntsig tseem ceeb tshaj plaws ntawm cov tub ntxhais amorphous yog qhov txo qis tsis muaj -load poob piv nrog cov nplej- taw qhia silicon steel. Hauv kev faib khoom siv hluav taws xob, tsis muaj -load poob yog tas mus li thiab dominates tag nrho lub zog poob ntawm chav tsev lub neej, tshwj xeeb tshaj yog nyob rau hauv lub teeb load. Amorphous alloy qhov qis coercivity thiab siab resistivity shrink ob hysteresis thiab eddy tam sim no poob, uas yog vim li cas amorphous -core tis transformers yog ib tug qauv kev daws teeb meem rau lub zog-efficiency cov kev pab cuam nyob rau hauv ntau lub teb chaws.
Cov khoom siv kuj teb rau cov tsis muaj zog to tam sim no thiab zam qhov cuam tshuam loj tam sim no, uas yog qhov tseem ceeb hauv cov khoom siv tam sim no thiab cov ntawv thov kev paub tam sim no uas yuav tsum tau muaj kev nkag siab thiab ruaj khov.

Lub thawv tiv thaiv qhov ntev (ID / OD / HT) nrog rau txhua qhov loj me los tiv thaiv cov npoo npoo thiab tiv thaiv cov khib nyiab. Cores nrog lwm cov kev qhia tshwj xeeb tuaj yeem muab tau raws li cov neeg siv khoom xav tau.
Kev xaiv thiab tuav kev txiav txim siab
Thaum xaiv ib qho amorphous core, xav txog kev khiav hauj lwm zaus, lub hom phiaj inductance, DC bias tam sim no thiab kub ntau ua ke. Amorphous ribbon yog rhiab heev rau cov neeg kho tshuab kev ntxhov siab, yog li cov cores yuav tsum tau saib xyuas, tiv thaiv hauv cov thawv, thiab sib sau ua ke nrog cov cuab yeej tsim nyog winding. Rau kev faib khoom siv hluav taws xob, lees paub qhov tsis muaj -load poob lub hom phiaj thiab cov qauv siv tau ua ntej xaiv ntawm amorphous thiab silicon steel cores.
FAQ
1. Yuav ua li cas qis dua qhov tsis muaj -load poob ntawm amorphous core piv nrog silicon steel?
