Kushandisa nzira ye inductive magnetic ring| GETWELL

Ndeipi nzira yekushandisa inductive magnetic ring ? Ndeupi musiyano uripo pakati peakasiyana inductor magineti mhete zvinhu? Ngatizivei pamwe chete.

Magnetic mhete chinhu chinowanzo shandiswa chinopesana nekupindira mumaseketi emagetsi, ane maitiro akanaka ekudzvinyirira paruzha rwepamusoro-soro, iyo yakaenzana nesefa yepasi-pasi. Inogona kugadzirisa zviri nani dambudziko rekudzvinyirirwa kwepamusoro-frequency kudzvanywa kwetambo dzemagetsi, mitsara yechiratidzo uye zvibatanidza, uye ine nhevedzano yezvakanakira, senge nyore kushandisa, yakanakira, inoshanda, nzvimbo diki uye zvichingodaro. Kushandisa ferrite anti-kupindira musimboti kudzvanya kukanganiswa kwemagetsi (EMI) inzira ine hupfumi, yakapusa uye inoshanda. Yakave ichishandiswa zvakanyanya mumakomputa uye zvimwe zvemagetsi zvemagetsi.

Ferrite imhando yeferrite inogadzirwa nekushandisa yakakwirira conductivity magineti kupinza imwe kana kupfuura mamwe magesium, zinc, nickel uye mamwe masimbi pa2000 ℃. Mune yakaderera frequency bhendi, iyo anti-kupindira magineti musimboti inoratidza yakaderera inductive impedance uye haina kukanganisa kutapurirana kwezviratidzo zvinobatsira pamutsetse wedata kana mutsara wechiratidzo. Mune yakakwirira frequency band, kutanga kubva ku10MHz, iyo impedance inowedzera, asi iyo inductance chikamu chinoramba chiri chidiki kwazvo, asi chinopikisa chikamu chinowedzera nekukurumidza. kana paine yakakwira frequency simba richipfuura nepakati pemagineti, iyo inopikisa chikamu inoshandura simba iri kuita rinopisa simba rekushandisa. Nenzira iyi, iyo yakaderera-pass sefa inovakwa, iyo inogona kudzoreredza yakanyanya-frequency ruzha chiratidzo, asi iyo impedance kune yakaderera-frequency chiratidzo chinobatsira chinogona kufuratirwa uye hachikanganisa kushanda kwakajairika kwedunhu. .

Maitiro ekushandisa iyo magineti ring ye anti-kupindira inductance:

1. Iise zvakananga pamagetsi emagetsi kana boka remitsara yezviratidzo. Kuti uwedzere kupindira uye kutora simba, unogona kutenderera kakawanda kakawanda.

2. Iyo anti-jamming magnetic ring ine mounting clip inokodzera kubhadharwa anti-jamming kudzvinyirira.

3. Inogona kusungirirwa nyore nyore patambo yemagetsi uye mutsara wechiratidzo.

4. Flexible uye reusable installation.

5. Mhando yekadhi yega yega yakagadziriswa, iyo isingakanganisi mufananidzo wose wemidziyo.

Musiyano pakati peZvinhu zvakasiyana zveInductance Magnetic Ring

Rudzi rwemagineti ring rinowanzo dema-dema, uye pamusoro pechindori chemagneti chine zvimedu zvakanaka, nekuti mazhinji acho anoshandiswa anti-kupindira, saka haawanzo kupendwa yegirini. Ehe, chikamu chidiki chayo chinoshandiswawo kugadzira inductors, uye yakapfapfaidzwa yakasvibira kuitira kuti iwane kuvharisa zviri nani uye kudzivirira kukuvadza waya enamelled zvakanyanya sezvinobvira. Muvara wacho pachawo hauna chekuita nekuita. Vazhinji vashandisi vanowanzobvunza, nzira yekusiyanisa pakati pe-high-frequency magnetic rings uye yakaderera-frequency magnetic rings? Kazhinji, iyo yakaderera-frequency magineti mhete yakasvibira uye yakakwirira-frequency magineti mhete ndeyezvisikwa.

Zvinowanzotarisirwa kuti permeability μ I uye resistivity ρ zvakakwirira, nepo kumanikidza Hc uye kurasikirwa kwePc zvakaderera. Zvinoenderana nekushandiswa kwakasiyana, kune zvakasiyana zvinodiwa kune tembiricha yeCurie, kugadzikana kwetembiricha, kuderedzwa kwepermeability coefficient uye chaiyo kurasikirwa coefficient.

Mhedzisiro huru ndeiyi:

(1) Manganese-zinc ferrites akakamurwa kuita maferi epamusoro uye akakwira-frequency yakaderera-simba ferrite (inozivikanwawo semagetsi ferrites). Hunhu hukuru hwepamusoro permeability mn-Zn ferrite yakanyanya kukwirira.

Kazhinji kutaura, zvinhu zvine μ I ≥ 5000 zvinodaidzwa kuti yakakwirira permeability zvinhu, uye μ I ≥ 12000 inowanzodiwa.

Mn-Zn yakakwira-frequency uye yakaderera-simba ferrite, inozivikanwawo sesimba ferrite, inoshandiswa mumagetsi ferrite zvinhu. zvinodiwa zvekushanda ndezvi: kukwirira kwepamusoro (kazhinji kunodiwa μ I ≥ 2000), tembiricha yeCurie yakakwirira, yakanyanya kuoneka density, yakakwira saturation magineti induction intensity uye magineti kurasikirwa kwepakati pakaderera frequency.

(2) Ni-Zn ferrite zvinhu, mune yakaderera frequency renji pazasi 1MHz, kuita kweNiZn ferrites hakuna kunaka seyeMnZn system, asi pamusoro pe1MHz, nekuda kweiyo porosity yakakwirira uye yakakwirira resistivity, iri nani kupfuura. MnZn system kuve yakanaka yakapfava magineti zvinhu mune yakakwirira frequency application. Iyo resistivity ρ yakakwira se 108 ω m uye iyo yakakwira frequency kurasikirwa idiki, saka inonyanya kukodzera kune yakakwira frequency 1MHz uye 300MHz, uye tembiricha yeCurie yeNiZn zvinhu yakakwira kupfuura MnZn,Bs uye inosvika 0.5T 10A/ m HC inogona kunge idiki se10A/m, saka yakakodzera kune ese marudzi einductor, transformers, sefa coils uye kukachidzwa coils. Ni-Zn yakakwira-frequency ferrite ine yakakura bandwidth uye yakaderera kutapurirana kurasikirwa, saka inowanzoshandiswa semagetsi emagetsi kupindira (EMI) uye redhiyo frequency interference (RFI) cores yekubatanidzwa kweiyo high frequency electromagnetic interference (EMI) uye pamusoro pemidziyo yekumisikidza. High frequency simba uye anti-kupindira. Ni-Zn simba ferrite inogona kushandiswa seRF Broadband zvishandiso kuona iyo simba rekufambisa uye impedance shanduko yeRF masaini mubhendi rakakura, ine yakaderera frequency muganho we akati wandei kilohertz uye yepamusoro frequency muganho wezviuru zve megahertz. Iyo Ni-Zn ferrite zvinhu inoshandiswa muDC-DC inoshandura inogona kuwedzera kuwanda kweiyo inoshandura magetsi uye kuwedzera kudzikisa huwandu uye huremu hwemagetsi ekushandura.

Yakajairwa magineti mhete-kune mhando mbiri dzemagineti mhete pamutsetse wekubatanidza, imwe nickel-zinc ferrite magineti mhete, imwe yacho manganese-zinc ferrite magineti mhete, vanoita mabasa akasiyana.

Mn-Zn ferrites ine hunhu hwepamusoro permeability uye yakanyanya flux density, uye ine hunhu hwekurasikirwa kwakaderera kana frequency yakadzikira kupfuura 1MHz.

Izvo zviri pamusoro ndiko kuiswa kwemagnetic ring inductors, kana iwe uchida kuziva zvakawanda nezve inductors, ndapota inzwa wakasununguka kutibata nesu.
