Hauv hluav taws xob engineering thiab hluav taws xob faib hluav taws xob, transformers ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ntseeg siab thiab ua haujlwm tau zoo los ntawm kev hloov hluav taws xob los ntawm ib qho hluav taws xob mus rau lwm qhov. Cov khoom siv tseem ceeb, lub ntsiab lus tseem ceeb hais txog kev ua haujlwm ntawm lub tshuab hluav taws xob thiab kev ua haujlwm, yog lub hauv paus ntawm cov khoom siv no. Nrog rau kev txhim kho thev naus laus zis, cov ntaub ntawv thiab cov txheej txheem siv los tsim cov transformer cores kuj hloov zuj zus. Cia peb tshawb nrhiav qhov xav paub yav tom ntej ntawm cov khoom siv hluav taws xob transformer thiab qhov kev nce qib tshiab tshaj plaws hauv kev lag luam.
Nanocrystalline Core Materials:
Tus thawj coj tshiab tej zaum cov ntaub ntawv Nanocrystalline sawv cev rau qhov kev vam meej loj hauv kev hloov pauv cov tub ntxhais thev naus laus zis. Muaj cov crystallites me me, feem ntau ntsuas hauv nanometers, cov ntaub ntawv no nthuav tawm cov khoom sib nqus zoo dua vim lawv cov microstructure zoo. Kev siv cov ntaub ntawv tseem ceeb nanocrystalline qhia pom kev txhim kho hauv kev ua tau zoo thiab kev ua haujlwm ntawm transformers, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas yuav tsum tau ua haujlwm siab.
Ib qho ntawm qhov zoo tshaj plaws ntawm nanocrystalline cov ntaub ntawv yog lawv cov hlau nplaum permeability siab, uas tso cai rau lawv los tswj cov hlau nplaum sib nqus ntau dua nrog tsawg zog poob. Cov cuab yeej no tau txais txiaj ntsig tshwj xeeb hauv cov tshuab hluav taws xob ntau zaus, vim lawv feem ntau raug kev txom nyem los ntawm kev poob qis tam sim no. Lub peev xwm los tswj cov kev ua haujlwm siab ntawm cov zaus siab ua rau nanocrystalline cores haum rau cov ntawv thov xws li cov tshuab hluav taws xob tauj dua tshiab, cov chaw nres tsheb fais fab, thiab cov khoom siv hluav taws xob siab heev.
Ntxiv nrog rau lawv cov kev ua tau zoo sib nqus, cov ntaub ntawv nanocrystalline tuaj yeem txhim kho thermal stability thiab txo cov suab nrov. Qhov txo cov tub ntxhais poob thiab zoo dua cov cua kub dissipation ua rau lub neej ntev dua rau transformers nruab nrog nanocrystalline cores. Tsis tas li ntawd, qhov kev vibration thiab acoustic suab nrov uas tshwm sim los ntawm alternating magnetic teb yog txo qis, ua rau kev ua haujlwm ntsiag to, uas yog ib qho tseem ceeb hauv kev siv hauv tsev thiab rhiab heev.
Txawm hais tias tus nqi tsim khoom ntawm nanocrystalline cov ntaub ntawv tam sim no siab dua li cov tsoos silicon steel, kev tshawb fawb thiab kev loj hlob tsis tu ncua txhawm rau txhawm rau txhim kho cov txheej txheem tsim khoom thiab txo cov nqi. Raws li cov ntaub ntawv no nce traction hauv kev lag luam, kev lag luam ntawm cov nplai thiab kev nce qib thev naus laus zis yuav tsum ua kom cov nanocrystalline cores nkag tau yooj yim dua thiab siv dav. Qhov kev hloov pauv no yog lwm kauj ruam mus rau yav tom ntej ntawm cov khoom siv hluav taws xob transformer, txhawb nqa los ntawm miniaturization, efficiency, thiab cov yam ntxwv ua haujlwm siab.
Tom ntej: SiliconLub luag haujlwm ntawm Hlau-raws li Soft Magnetic Composites
Kev lag luam tseem tab tom pom kev hloov pauv nrog kev txaus siab loj hlob ntawm cov hlau nplaum sib nqus sib nqus (SMCs). Tsis zoo li cov khoom siv hluav taws xob zoo sib xws, SMCs yog tsim los ntawm ferromagnetic particles embedded nyob rau hauv ib tug insulating matrix. Qhov kev teeb tsa tshwj xeeb no tso cai rau cov khoom sib nqus sib nqus thiab qhib lub qhov rooj rau qhov tsim qauv yooj yim thiab kev hloov kho hauv kev tsim cov tub ntxhais transformer.
Hlau-based SMCs nthuav tawm cov khoom sib nqus zoo tshaj plaws, suav nrog kev ua kom muaj zog thiab tsis muaj zog, uas pab txo qis hysteresis poob. Ib qho ntawm cov yam ntxwv ntawm SMCs yog lawv lub peev xwm los txo qis qhov poob tam sim no, ua tsaug rau qhov insulating xwm ntawm cov khoom siv matrix. Qhov kom zoo dua no yog qhov tshwj xeeb hauv cov ntawv thov uas xav tau kev ua haujlwm siab, zoo ib yam li cov ntaub ntawv nanocrystalline.
Dab tsi ua rau SMCs sib nrug yog lawv qhov yooj yim tsim. Lub versatility nyob rau hauv shaping thiab structuring cov ntaub ntawv no tso cai rau lub tshiab geometries uas yav tas los unattainable nrog ib txwm cov ntaub ntawv. Qhov kev muaj peev xwm no yog qhov tseem ceeb rau kev sib koom ua ke transformers rau hauv qhov chaw compact lossis tsim cov chav nrog cov kev xav tau tshwj xeeb thermal tswj. Tsis tas li ntawd, SMCs tuaj yeem tsim tau siv cov txheej txheem nqi zoo xws li hmoov metallurgy, uas qhib txoj hauv kev tshiab rau kev lag luam thiab kev ua haujlwm siab transformer cores.
Tsis tas li ntawd, kev txhim kho ntawm cov hlau-raws li SMCs ua ke nrog cov kev coj ua ruaj khov. Cov txheej txheem tsim khoom feem ntau suav nrog kev siv hluav taws xob qis dua thiab tso tawm tsawg dua lub tsev cog khoom gases piv rau cov qauv siv. Qhov txiaj ntsig ntawm ecological no, ua ke nrog kev ua tau zoo ntawm cov khoom siv, ua haujlwm hlau-raws li SMCs ua ib qho kev sib cav sib ceg hauv toj roob hauv pes ntawm cov khoom siv tseem ceeb ntawm cov khoom siv tam sim no. Kev tshawb fawb tsis tu ncua thiab kev sib koom tes hauv kev ua haujlwm yuav tsum tau ua kom zoo dua cov ntaub ntawv no thiab ua kom lawv lub luag haujlwm nyob rau hauv lub neej yav tom ntej ntawm transformer technology.
Xav kom kev lag luam transformer zoo dua yav tom ntej !!
