Dab Tsi Yog Ib Qhov Txiaj Ntsig Ntau Hom Txwm Txheeb | TAU TXAIS

Puas muaj thaj ua rau thaj rau cov hom inductors? Qhov no yuav tsum yog ib tug ntau ntawm cov neeg muas zaub thiab tub lag luam ntawm cov ntseeg? Cov hom khaub thuas daig caj pas chaw tsim tshuaj paus Getwell yuav teb cov hom zawm caj pas yog nyob rau hauv lub kawg yog tsis muaj thaj;

Peb yuav tsum nkag siab tias nws ua haujlwm li cas; Hom hom inductors muaj qhov pib siab permeability, loj impedance thiab tso tsis tau zoo nyob rau hauv geomagnetic teb, cuam tshuam zoo los cuam tshuam kev cuam tshuam, thiab tsis muaj resonant insertion poob nyob rau hauv ntau zaus ntau.

hom khaub thuas sib txawv heev rau hauv lub neej txhua hnub. Hauv daim ntawv thov ntawm lub khoos phis tawm, muaj ntau lub xov tooj hluav taws xob ntau, cov xov tooj cua digital thiab cov hluav taws xob sib xyaw tau sib xyaw ua ke ntawm lub koos pij tawj sab hauv. Thaum lawv ua haujlwm, lawv tsim ntau lub xov tooj ntawm lub tshuab hluav taws xob tsawg thiab cuam tshuam rau lwm tus, xws li EMI.Electromagnetic cuam tshuam tseem yuav tawm sab nraud los ntawm tus neeg xyuas pib lossis sab nraud cable ntawm lub motherboard, ua rau hluav taws xob hluav taws xob, tsis tsuas cuam tshuam rau ib txwm ua haujlwm ntawm lwm yam khoom siv hluav taws xob, tab sis kuj tsim kev puas tsuaj rau tib neeg lub cev.

Puas muaj thaj ua rau thaj rau hom kev ua inductors?

Qhov no nyob ntawm hom hom choke.Nws zoo sib xws hauv kev teeb tsa thiab ua haujlwm rau hom ncaj ncees vim hais tias ntawm lub nti hom hom inductor.

hom hom pa roj carbon monoxide muaj cov kauj vuam winding puag ncig thiab puag ncig ntawm cov kab hluav taws xob insulating, uas yog cov rwb thaiv los ntawm sib. Txoj kab hauv kab hluav taws xob tuaj yeem hollow lossis muaj cov tub ntxhais hlau lossis cov hmoov sib nqus, uas yog xa mus ua inductance.In L, cov chav nyob yog Henry (H) thiab milliHenry

(mH), micro Henry (uH), 1H = 10 ^ 3mH = 10 ^ 6uH.

Kev faib ua hom ntawm hom inductors.

Dej num los ntawm inductance daim ntawv: tsau inductance, kuj tsis paub meej inductance.

Qhia raws li cov yam ntxwv ntawm tus neeg xyuas pib sib nqus: hollow kauj, ferrite kauj, hlau kauj, tooj liab kauj.

Cais raws cov xwm ntawm kev ua haujlwm: kav hlau txais xov, chev oscillating chev, txhawm chim coil, cuab kauj, deflection chev.

Ua kom raws cov qauv winding: ib leeg-txheej chev, ntau txheej txheej, muaj log ua ke sib tshooj.

Tus yam ntxwv tseem ceeb ntawm cov kauj inductance:

1.Inductance L

Ind Indentance L sawv cev rau qhov sib xws ntawm lub kauj nws tus kheej, ywj siab ntawm cov hom uas tam sim no loj dua.Yog tshwj xeeb rau cov coos tshwj xeeb (cov cim xim inductors), qhov inductance feem ntau tsis cim ntawm coil, tab sis los ntawm lub npe tshwj xeeb.

2.ntawm XL

Qhov loj ntawm lub inductance kauj ntawm AC tam sim no ob leeg hu ua inductive reactance XL, chav tsev yog ohm.Its piv rau qhov inductance L thiab hloov pauv tam sim no F yog XL = 2πfL

3.Quality yam Q

Kev ua tau zoo Q yog qhov ua kom lub cev ua kom zoo rau lub coil zoo, Q yog qhov sib piv ntawm kev tiv thaiv kev tiv thaiv XL thiab qhov sib npaug tsis kam, uas yog: Q = XL / R.

Qhov siab dua Q tus nqi ntawm cov kauj, qhov me dua qhov poob ntawm lub voj.Qhov Q tus nqi ntawm lub kauj yog cuam tshuam nrog DC tsis kam ntawm cov hlau, dielectric poob pob txha, poob los ntawm daim hlau lossis cov tub ntxhais hlau, thiab qhov cuam tshuam ntawm daim tawv nqaij cuam tshuam ntawm kev loj.Qhov Q tus nqi ntawm lub kauj feem ntau li ntawm kaum tawm txog ntau pua.

4.distributed capacitance

Lub nruab nrab ntawm qhov coil hloov thiab tig rov qab, nruab nrab ntawm lub kauj thiab cov ntaub thaiv npog, nruab nrab ntawm lub kauj thiab lub phaj hu ua lub zog faib tawm.Qhov muaj nyob ntawm faib capacitance txo Q tus nqi ntawm lub coil thiab ua rau kev ruaj khov. Yog li ntawd, qhov tsawg dua qhov faib cov peev txheej ntawm lub kauj, qhov zoo dua.

Cov hom inductors uas nquag siv coils yog:

1.Single txheej kauj

Ib txheej txheej tsim yog ua los ntawm cov kab hlau tsis muaj kab thiab puag ncig ntawm ib daim ntawv raj lossis bakelite ncej.Such li transistorized xov tooj cua nruab nrab yoj kav hlau txais xov lub kauj.

2.Honeycomb kauj

Yog hais tias lub npov hla dhau, nws cov dav hlau tsis sib txuas nrog rau saum npoo ntawm kev sib hloov, tab sis sib tshuam ntawm lub kaum sab xis txhais los ntawm Yi. Qhov no hu ua honeycomb coil.Thiab tus naj npawb ntawm cov xov hlau khoov rov qab thiab tom qab nws tig ib zaug, feem ntau yog hu ua tus lej ntawm khoov cov ntsiab lus.Qhov hom no muaj qhov zoo ntawm cov ntim me me, faib me me muaj peev xwm thiab qhov loj inductance.The honeycomb winding tshuab yog siv los txhawm rau lub coils hauv honeycomb. Qhov ntau cov ntsiab lus folding, qhov me me muab faib rau qhov muaj peev xwm faib tawm.

3.Ferrite core thiab hlau hmoov tub ntxhais kauj

Qhov inductance ntawm lub kauj muaj feem xyuam nrog qhov muaj lossis tsis muaj qhov sib nqus ntawm cov hlau nplaum.Inserting core ferrite mus rau hauv lub hollow kauj tuaj yeem nce qhov inductance thiab txhim kho qhov zoo ntawm lub kauj.

4.Qhov kauj

Cov tub ntxhais tooj liab tooj liab tau dav siv nyob rau hauv qhov nruab nrab ntawm ultrashort nthwv dej. Txoj hauj lwm ntawm tooj liab cov kauj kauj yog tig kom hloov qhov hloov pauv, uas yooj yim thiab ruaj khov.

5.Color code inductor

Cov xim xim inductor yog qhov pib nrog kev sib hloov pauv, thiab nws cov inductance yog cim los ntawm cov nplhaib xim raws li cov thev.

6.Xav chev (txhawm chim chev)

Lub kauj uas txwv cov dej ntws ntawm kev hloov pauv tam sim no yog hu ua choke coil, uas tau muab faib ua ntau zaus txhawm rau txhawm rau txhawm rau thiab tsawg zaus choke coil.

7.Txhais xim txheej

Deflection coil yog cov zis load ntawm TV scanning Circuit. Deflection chev yuav tsum muaj siab deflection rhiab heev, uniform magnetic teb, Q siab tus nqi, me me thiab tus nqi qis.

Qhov saum toj no yog kev paub ntawm SMT hom hom kev ua haujlwm txhawm chim, vam tias yuav pab koj rau qee yam.Peb yog cov chaw muag khoom xa tuaj ntawm Tuam Tshoj - Getwell Electronics.Yog hais tias koj tsis nkag siab, zoo siab txais tos tham nrog peb!
