Daim ntawv thov txheej txheem ntawm inductive magnetic nplhaib | TAU TXAIS

Txoj kev siv inductive magnetic nplhaib yog dab tsi? Dab tsi yog qhov sib txawv ntawm cov khoom sib nqus sib nqus inductor? Cia peb tau paub ua ke.

Lub nplhaib sib nqus yog ib qho siv los tiv thaiv kev cuam tshuam hauv cov hluav taws xob hluav taws xob, uas muaj kev cuam tshuam zoo ntawm lub suab nrov nrov, uas yog sib npaug rau cov lim dej qis. Nws tuaj yeem daws tau qhov teeb meem ntawm kev cuam tshuam ntau zaus ntawm cov kab hluav taws xob, cov kab teeb liab thiab cov khoom sib txuas, thiab muaj cov txiaj ntsig zoo, xws li kev siv yooj yim, yooj yim, zoo, qhov chaw me me thiab lwm yam. Siv ferrite los tiv thaiv kev cuam tshuam core los tiv thaiv electromagnetic cuam tshuam (EMI) yog ib qho kev lag luam, yooj yim thiab siv tau zoo. Nws tau dav siv hauv computers thiab lwm yam khoom siv hluav taws xob hauv pej xeem.

Ferrite yog ib hom ferrite uas tau npaj los ntawm kev siv cov khoom siv hluav taws xob sib nqus kom nkag mus rau ib lossis ntau dua lwm yam magnesium, zinc, nickel thiab lwm yam hlau ntawm 2000 ℃. Nyob rau hauv qhov tsawg zaus band, lub anti-interference magnetic core qhia ib tug heev tsawg inductive impedance thiab tsis cuam tshuam rau cov kis tau tus mob ntawm cov teeb liab muaj txiaj ntsig ntawm cov ntaub ntawv kab lossis kab teeb liab. Nyob rau hauv lub siab zaus band, pib ntawm 10MHz, lub impedance nce, tab sis lub inductance tivthaiv tseem me me, tab sis lub resistive tivthaiv nce sai heev. Thaum muaj lub zog ntau zaus dhau los ntawm cov khoom sib nqus, cov khoom tiv thaiv tiv thaiv yuav hloov cov zog no rau hauv thermal zog noj. Nyob rau hauv txoj kev no, lub lim dej qis dhau yog tsim, uas tuaj yeem ua rau lub suab nrov nrov heev, tab sis lub impedance rau cov teeb liab muaj txiaj ntsig tsawg tuaj yeem tsis quav ntsej thiab tsis cuam tshuam rau kev ua haujlwm ntawm lub voj voog. .

Yuav ua li cas siv lub nplhaib sib nqus ntawm kev cuam tshuam inductance:

1. Muab nws ncaj qha rau ntawm lub hwj huam mov lossis ib pawg ntawm cov kab teeb liab. Txhawm rau kom muaj kev cuam tshuam thiab nqus tau lub zog, koj tuaj yeem ncig nws ob peb zaug ntau zaus.

2. Anti-jamming magnetic nplhaib nrog mounting clip yog tsim rau compensated anti-jamming suppression.

3. Nws tuaj yeem yooj yim clamped ntawm lub hwj chim qaum thiab cov teeb liab kab.

4. Saj zawg zog thiab reusable installation.

5. Hom daim npav tus kheej yog kho, uas tsis cuam tshuam rau tag nrho cov duab ntawm cov khoom siv.

Qhov sib txawv ntawm cov khoom sib txawv ntawm Inductance Sib Nqus Ring

Cov xim ntawm lub nplhaib hlau nplaum feem ntau yog ntuj-dub, thiab qhov saum npoo ntawm lub nplhaib hlau nplaum muaj cov khoom zoo, vim lawv feem ntau yog siv los tiv thaiv kev cuam tshuam, yog li lawv tsis tshua muaj xim ntsuab. Tau kawg, ib feem me me ntawm nws kuj yog siv los ua inductors, thiab nws yog txau ntsuab kom ua tiav cov rwb thaiv tsev zoo dua thiab tsis txhob ua mob rau cov hlau enamelled ntau li ntau tau. Cov xim nws tus kheej tsis muaj dab tsi ua nrog kev ua haujlwm. Ntau tus neeg siv feem ntau nug, yuav ua li cas paub qhov txawv ntawm qhov sib nqus sib nqus rings thiab tsawg zaus sib nqus rings? Feem ntau, lub nplhaib sib nqus tsis tshua muaj xim ntsuab thiab lub nplhaib sib nqus sib nqus yog ntuj.

Nws yog feem ntau xav tias qhov permeability μ I thiab resistivity ρ yog siab, thaum lub coercivity Hc thiab poob Pc yog tsawg. Raws li kev siv sib txawv, muaj cov kev xav tau sib txawv rau Curie kub, kub stability, permeability txo coefficient thiab tshwj xeeb poob coefficient.

Cov txiaj ntsig tseem ceeb yog raws li hauv qab no:

(1) Manganese-zinc ferrites muab faib ua high permeability ferrites thiab high-frequency low-power ferrites (tseem hu ua fais fab ferrites). Lub ntsiab yam ntxwv ntawm siab permeability mn-Zn ferrite yog heev permeability.

Feem ntau hais lus, cov ntaub ntawv nrog μ I ≥ 5000 yog hu ua cov khoom permeability siab, thiab μ I ≥ 12000 feem ntau xav tau.

Mn-Zn high-frequency thiab low-power ferrite, tseem hu ua fais fab ferrite, yog siv rau hauv cov khoom siv fais fab ferrite. Cov kev ua tau zoo yog: siab permeability (feem ntau yuav tsum tau μ I ≥ 2000), siab Curie kub, siab pom tseeb ntom, siab saturation sib nqus induction siv thiab sib nqus core poob ntawm tsawg zaus.

(2) Ni-Zn ferrite cov ntaub ntawv, nyob rau hauv qhov tsawg zaus ntau yam hauv qab no 1MHz, kev ua tau zoo ntawm NiZn ferrites tsis zoo li ntawm MnZn system, tab sis siab tshaj 1MHz, vim nws cov porosity siab thiab siab resistivity, nws yog ntau zoo dua. MnZn system kom dhau los ua cov khoom sib nqus zoo hauv cov ntawv thov ntau zaus. Lub resistivity ρ yog siab li 108 ω m thiab qhov siab zaus poob yog me me, yog li nws yog tshwj xeeb tshaj yog haum rau high zaus 1MHz thiab 300MHz, thiab Curie kub ntawm NiZn khoom yog siab tshaj MnZn, Bs thiab mus txog 0.5T 10A / m HC tuaj yeem ua me me li 10A / m, yog li nws tsim nyog rau txhua yam inductors, transformers, lim coils thiab choke coils. Ni-Zn high-frequency ferrites muaj qhov dav bandwidth thiab tsis tshua muaj kev sib kis, yog li lawv feem ntau siv los ua electromagnetic cuam tshuam (EMI) thiab xov tooj cua zaus cuam tshuam (RFI) cores rau kev koom ua ke ntawm high zaus electromagnetic cuam tshuam (EMI) thiab nto mount li. Lub zog ntau zaus thiab tiv thaiv kev cuam tshuam. Ni-Zn fais fab ferrites tuaj yeem siv los ua RF broadband pab kiag li lawm kom paub lub zog xa mus thiab impedance hloov dua siab tshiab ntawm RF signals nyob rau hauv ib tug dav band, nrog ib tug tsawg zaus txwv ntawm ob peb kilohertz thiab ib tug siab zaus txwv ntawm ntau txhiab megahertz. Cov khoom siv Ni-Zn ferrite siv nyob rau hauv DC-DC converter tuaj yeem nce qhov zaus ntawm kev hloov hluav taws xob thiab txo qhov ntim thiab qhov hnyav ntawm lub tshuab hluav taws xob.

Cov nplhaib sib nqus-muaj nyob rau hauv ob hom sib nqus rings ntawm cov kab sib txuas dav dav, ib qho yog npib tsib xee-zinc ferrite magnetic nplhaib, lwm qhov yog manganese-zinc ferrite magnetic nplhaib, lawv ua lub luag haujlwm sib txawv.

Mn-Zn ferrites muaj cov yam ntxwv ntawm siab permeability thiab siab flux ceev, thiab muaj cov yam ntxwv ntawm kev poob qis thaum lub zaus qis dua 1MHz.

Cov saum toj no yog cov kev taw qhia ntawm magnetic nplhaib inductors, yog tias koj xav paub ntau ntxiv txog inductors, thov koj xav tiv tauj peb.
