Txheej txheem cej luam ntawm Inductance Properties| TAU TXAIS

Nyob rau hauv ib lub voj voog, ib qho hluav taws xob electromagnetic yog tsim thaum tam sim no ntws los ntawm tus neeg xyuas pib. Qhov loj ntawm electromagnetic teb faib los ntawm tam sim no yog inductance .

Inductance yog ib lub cev kom muaj nuj nqis uas ntsuas lub peev xwm ntawm lub kauj los tsim electromagnetic induction. Yog hais tias ib qho hluav taws xob tam sim no siv rau lub kauj, ib qho chaw sib nqus yuav raug tsim nyob ib ncig ntawm lub kauj, thiab lub kauj yuav muaj cov hlau nplaum sib nqus los ntawm nws. Qhov ntau dua qhov hluav taws xob nkag mus rau hauv lub kauj, qhov muaj zog ntawm cov hlau nplaum thiab qhov sib nqus flux ntau dua los ntawm lub kauj. Cov kev sim qhia tau hais tias qhov sib nqus flux los ntawm lub kauj yog proportional rau cov khoom tam sim no, thiab lawv qhov piv yog hu ua self-inductance, los yog inductance.

Kev faib tawm ntawm inductance

Muab faib raws li daim ntawv ntawm inductor: tsau inductor, sib txawv inductor.

Muab faib raws li cov khoom ntawm cov hlau nplaum: hollow coil, ferrite coil, hlau tub ntxhais kauj, tooj liab tub ntxhais kauj.

Muab faib los ntawm kev ua haujlwm: kav hlau txais xov coil, oscillation coil, choke coil, notch coil, deflection coil.

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

Muab faib los ntawm kev ua haujlwm zaus: siab zaus coil, qis zaus coil.

Muab faib raws li cov yam ntxwv ntawm cov yam ntxwv: sib nqus core coil, sib txawv inductance coil, xim code inductor coil, non-core coil thiab lwm yam.

Hollow inductors, sib nqus core inductors thiab tooj liab tub ntxhais inductors feem ntau yog nruab nrab zaus lossis siab zaus inductors, thaum cov tub ntxhais hlau inductors feem ntau tsawg zaus inductors.

Khoom siv thiab technology ntawm inductor

Inductors feem ntau yog tsim los ntawm cov pob txha, winding, shield, ntim khoom, cov tub ntxhais hlau nplaum thiab lwm yam.

1) Skeleton: feem ntau yog hais txog kev txhawb nqa rau winding coils. Nws feem ntau yog ua los ntawm cov yas, Bakelite thiab ceramics, uas tuaj yeem ua rau cov duab sib txawv raws li qhov xav tau tiag tiag. Cov inductors me feem ntau tsis siv lub cev pob txha, tab sis cua cov hlau enamelled ncaj qha nyob ib ncig ntawm cov tub ntxhais. Lub hollow inductor tsis siv cov tub ntxhais sib nqus, lub cev pob txha thiab cov ntaub thaiv npog, tab sis ua ntej qhov txhab ntawm cov pwm thiab tom qab ntawd tshem tawm cov pwm, thiab rub ib qho kev ncua deb ntawm cov coils.

2) Winding: ib pawg coils nrog cov haujlwm tshwj xeeb, uas tuaj yeem muab faib ua ib txheej thiab ntau txheej. Cov txheej txheem ib leeg muaj ob hom kev sib tw winding thiab indirect winding, thiab cov txheej txheem ntau yam muaj ntau txoj hauv kev, xws li txheej txheej winding, random winding, honeycomb winding thiab lwm yam.

3) Cov tub ntxhais sib nqus: feem ntau siv cov nickel-zinc ferrite lossis manganese-zinc ferrite thiab lwm yam ntaub ntawv, nws muaj "Kuv" zoo, kem puab, cap puab, "E" puab, tank puab thiab hais txog.

Cov tub ntxhais hlau: feem ntau yog silicon steel ntawv, permalloy thiab lwm yam, nws cov duab feem ntau yog "E" hom.

Kev tiv thaiv npog: siv los tiv thaiv cov hlau nplaum uas tsim los ntawm qee qhov inductors los ntawm kev cuam tshuam rau kev ua haujlwm ntawm lwm cov circuits thiab cov khoom siv. Lub inductor nrog shielding npog yuav ua rau kom poob ntawm lub kauj thiab txo tus nqi Q.

Cov khoom ntim: tom qab qee qhov inductors (xws li xim code inductor, xim nplhaib inductor, thiab lwm yam) raug mob, lub kauj thiab cov tub ntxhais raug kaw nrog cov khoom ntim. Cov khoom ntim yog ua los ntawm cov yas lossis epoxy resin.

Cov saum toj no yog cov ntsiab lus ntawm cov khoom ntawm inductors, yog tias koj xav paub ntau ntxiv txog inductors, thov hu rau peb.
