Piv nrog rau cov tsoos ferrite core transformers, amorphous core transformers tau txais kev saib xyuas zoo nyob rau xyoo tas los no vim lawv qhov tshwj xeeb muaj pes tsawg leeg thiab kev ua tau zoo.Cov transformers no yog tsim los ntawm cov khoom siv hlau nplaum tshwj xeeb hu ua amorphous alloy, uas muaj cov khoom tshwj xeeb uas ua rau nws xaiv thawj zaug rau ntau yam kev siv.Hauv tsab xov xwm no, peb yuav tshawb xyuas qhov tseeb ntawm amorphous core yog dab tsi, qhia txog qhov sib txawv ntawm amorphous core transformers thiab ferrite core transformers, thiab sib tham txog qhov zoo ntawm kev siv.amorphous coretransformers.
Yog li, dab tsi yog amorphous magnetic core?Amorphous magnetic cores muaj cov hlau nplaum nyias uas muaj ntau yam hlau, feem ntau suav nrog hlau ua lub hauv paus tseem ceeb thiab kev sib xyaw ntawm boron, silicon, thiab phosphorus.Tsis zoo li cov khoom siv crystalline hauv ferrite cores, cov atoms hauv amorphous alloys tsis pom cov qauv atomic li niaj zaus, yog li lub npe "amorphous."Vim yog qhov tshwj xeeb atomic kev npaj, amorphous cores muaj cov khoom sib nqus zoo heev.
Qhov sib txawv tseem ceeb tshaj plaws ntawm amorphous core thiab ferrite core transformers yog lawv cov khoom tseem ceeb.Amorphous cores siv cov ntsiab lus saum toj no amorphous alloys, thaum ferrite cores yog tsim los ntawm cov khoom siv ceramic uas muaj hlau oxide thiab lwm yam khoom.Qhov sib txawv ntawm cov ntaub ntawv tseem ceeb no ua rau muaj cov yam ntxwv sib txawv ntawm cov transformer thiab kev ua haujlwm.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawmamorphous coretransformers yog lawv cov tseem ceeb poob poob.Core poob yog hais txog lub zog dissipated nyob rau hauv lub transformer core, uas ua rau nkim fais fab thiab nce tshav kub.Piv rau ferrite cores, amorphous cores muaj qhov txo qis hysteresis thiab eddy tam sim no poob, uas ua rau muaj kev ua tau zoo dua thiab ua haujlwm qis dua.Kev txhim kho kev ua tau zoo ntawm 30% mus rau 70% piv rau cov qauv hloov pauv ua rau amorphous core transformers ib qho kev xaiv zoo rau kev lag luam txuag hluav taws xob.
Tsis tas li ntawd, amorphous cores muaj cov khoom sib nqus zoo heev, nrog rau kev ua kom muaj kuab paug siab.Saturation magnetic flux density yog hais txog qhov siab tshaj plaws sib nqus flux uas cov khoom tseem ceeb tuaj yeem ua raws.Amorphous alloys muaj ntau dua saturation flux densities piv rau ferrite cores, tso cai rau me me, sib zog transformers thiab muaj zog zog ceev.Qhov txiaj ntsig no tshwj xeeb yog qhov muaj txiaj ntsig zoo rau cov ntawv thov uas qhov loj thiab qhov hnyav yog qhov tseem ceeb, xws li hluav taws xob hluav taws xob, hluav taws xob hluav taws xob txuas ntxiv thiab tsheb hluav taws xob.
Lwm qhov zoo dua ntawm amorphous core transformers yog lawv cov kev ua haujlwm siab tshaj plaws.Vim lawv cov qauv atomic tshwj xeeb, amorphous alloys pom cov tub ntxhais poob qis dua ntawm cov zaus ntau dua, ua rau lawv zoo tagnrho rau cov ntawv thov cuam tshuam nrog kev cuam tshuam ntau zaus electromagnetic cuam tshuam (EMI) mitigation.Cov yam ntxwv no ua rau amorphous core transformers kom muaj txiaj ntsig zoo EMI suab nrov, yog li txhim kho kev ntseeg tau thiab txo kev cuam tshuam hauv cov khoom siv hluav taws xob.
Txawm hais tias cov txiaj ntsig zoo li no,amorphous coretransformers muaj qee qhov kev txwv.Ua ntej, tus nqi ntawm amorphous alloys yog siab dua li cov ntaub ntawv ferrite, uas cuam tshuam rau thawj zaug peev nqi ntawm transformer.Txawm li cas los xij, kev txuag hluav taws xob mus sij hawm ntev tau ua tiav los ntawm kev ua tau zoo dua feem ntau them rau cov nqi pib dua.Thib ob, cov khoom siv kho tshuab ntawm amorphous alloys feem ntau tsis zoo rau cov ferrite cores, ua rau lawv muaj kev cuam tshuam rau cov neeg kho tshuab kev ntxhov siab thiab muaj peev xwm puas tsuaj.Kev txiav txim siab tsim nyog thiab cov txheej txheem ua tiav yog qhov tseem ceeb rau kev ua kom lub neej ntev thiab kev ntseeg siab ntawm amorphous core transformers.
Hauv cov ntsiab lus, amorphous core transformers muaj ntau yam zoo dua cov tsoos ferrite core transformers.Lawv qhov kev poob qis, kev ua haujlwm siab sib nqus, kev ua haujlwm siab zaus, thiab qhov loj me thiab qhov hnyav ua rau lawv xaiv qhov zoo nkauj rau ntau yam kev siv.Raws li qhov kev thov rau lub zog siv hluav taws xob txuas ntxiv mus ntxiv, amorphous core transformers yuav ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li cov kev xav tau no thiab tsav kev lag luam mus rau ib qho chaw ntsuab, zoo dua yav tom ntej.
