Kev npaj:
Lub Center Pillar (1) yog teem nyob nruab nrab ntawm qhov nruab nrab ntawm lub sab sauv thiab sab yokes (2, 3), nrog ib tug coil (5) mob nyob ib ncig ntawm nws.
Lub Siab -Permeability Sab Ncej (4) yog teem caij nyob nruab nrab ntawm cov npoo sab saud ntawm sab sauv thiab sab qis (2, 3).
Cov txiaj ntsig: Cov khoom tsim thiab ntau- txoj kev sib nqus hluav taws xob cov qauv tiv thaiv tus quab los ntawm saturating ntxov ntxov, zoo siv lub quab yuam, dispersing magnetic flux, thiab tso cai rau txo tus quab thickness.
II. Keeb kwm thiab piav qhia ntawm Invention
A. Cov teeb meem ntawm kev kos duab ua ntej
Cov pa siab siab - zaus reactors, feem ntau hloov cov tsoos silicon steel sheet reactors, ntsib ob peb yam nyuaj:
Annular Reactors: Nyuaj winding thiab nyuaj rau loj - teev ntau lawm.
Stacked Hlau Powder Core Reactors (E-core style): Txawm hais tias zoo dua li annular, cov kev daws teeb meem ua ntej tseem muaj kev txwv:
Sib Nqus Resin Pob: Tsawg permeability ntawm cov khoom sib nqus txwv qhov kev txhim kho ntawm kev siv tus quab.
Hybrid Material Designs: Txawm hais tias compact thiab ua tau zoo, lawv feem ntau muaj teeb meem kev tsim khoom, tshwj xeeb tshaj yog rau qhov loj me.
Ferrite Slab Core / Hybrid Sib Nqus Circuit Court: Tsis yooj yim ua rau cov ferrite slab core nyias thiab ua rau muaj kev pheej hmoo ntawm saturation thaum ntxov hauv cov khoom ferrite.
B. Kev daws teeb meem thiab teeb tsa
Lub invention daws cov teeb meem ntawm cov kos duab ua ntej los ntawm kev siv ib tug hybrid core qauv thiab cov khoom xaiv los tswj magnetic flux tis thiab saturation.
Paub meej Configuration:
Core Material Xaiv:
Lub Chaw Pillar (1) cov khoom raug xaiv kom muaj qhov sib nqus sib nqus flux ntom ntom (B1) ntau dua li ntawm Sab Nraud Yoke (2) thiab qis Yoke (3) khoom (B2).
Cov ntaub ntawv xav tau: Center Pillar: Hlau hmoov core (Sendust lossis hlau silicon aluminium); Khoom siv: Ferrite.
Lub siab -Permeability Sab Posts (4) muaj qhov permeability ntawm Ntau dua lossis sib npaug rau 200 thiab zoo dua ua los ntawm cov khoom siv ferrite lossis amorphous.
Structure thiab Assembly:
Lub Center Pillar (1) muaj lub kauj (5) qhov txhab ntawm nws sab nrauv. Cov pa sib txawv tuaj yeem muab rau ntawm tus ncej nruab nrab (1).
Yoke Connection: Lub hauv paus ncej (1) tuaj yeem muab tso rau hauv lub yokes sab sauv thiab qis lossis txawm nkag mus rau lawv.
Insertion Depth Requirement: Yog tias muab tso rau, qhov sib piv ntawm qhov tob tob (D) rau lub yoke thickness (D'), D'D , yuav tsum tau ntau dua los yog sib npaug rau B1B1-B2 txhawm rau tiv thaiv tus quab ntawm ferrite khoom los ntawm saturating ntxov ntxov.
Sab Tshaj Tawm: Yam tsawg kawg yog ob qhov siab -Permeability Side Posts (4) yog muab tso rau nruab nrab ntawm cov npoo sab nraud ntawm tus quab, zoo dua symmetrically faib nyob ib ncig ntawm tus ncej hauv nruab nrab. Cov kab ntawv sab no tsim ntau yam sib nqus flux loops kom zoo disperse cov magnetic flux.
Reactor Assembly: Lub reactor tiav suav nrog lub kauj (5) qhov txhab sab nraud ntawm tus ncej nruab nrab (1).
Rwb thaiv tsev: Insulating kawg rings yog muab rau sab saum toj thiab hauv qab ntawm lub kauj kom cais nws los ntawm lub hauv paus ncej thiab cov yokes.
Optional Casing: Ib rooj plaub tuaj yeem muab tso rau sab nraum lub hauv paus, uas tuaj yeem ntim nrog cov kua nplaum kom sib koom ua ke txhua qhov chaw.
C. Cov txiaj ntsig zoo
Txhim Kho Kev Siv Yoke: Kev siv cov khoom siv siab - saturation rau lub hauv paus ncej thiab qhov ntxig rau hauv cov yokes tiv thaiv kev saturation ntxov ntawm tus quab ferrite, tso cai rau qhov chaw quab yuam kom siv tau zoo.
Compact Structure thiab Manufacturing yooj yim: Kev siv yam tsawg kawg yog ob lub siab -permeability sab kab ua ntau yam sib nqus flux loops, dispersing cov magnetic flux. Qhov no tso cai rau lub thickness ntawm tus quab yuav raug txo, ua rau ib tug compact thiab yooj yim tsim qauv.
Tiv Thaiv Thaum Ntxov Saturation: Qhov tsim qhov tob tob kom ntseeg tau tias cov khoom siv yoke raug tiv thaiv los ntawm kev ua kom tsis txaus.
