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