Koyilo wamba

1. Koyilo imodzi yosanjikiza

Koyilo yamtundu umodzi imakulungidwa mozungulira chubu la pepala kapena mafupa a bakelite okhala ndi mawaya otsekeredwa chimodzi ndi chimodzi. Monga ngati koyilo ya mlongoti wozungulira mu wailesi ya transistor.

2. Chisa cha uchi

Ngati ndege ya chilonda koyilo si kufanana ndi kasinthasintha padziko, koma intersects pa ngodya inayake, mtundu uwu wa koyilo amatchedwa zisa koyilo. Ndipo kuchuluka kwa nthawi zomwe waya amapindika uku ndi uku akamazungulira kamodzi, zomwe nthawi zambiri zimatchedwa kuchuluka kwa mfundo zopinda. Njira yokhotakhota ya uchi ili ndi ubwino wa voliyumu yaying'ono, mphamvu yaing'ono yogawidwa ndi inductance yaikulu. Zozungulira zisa zonse zimavulazidwa ndi makina omangira zisa. Kuchuluka kopindika, kumachepetsa mphamvu yogawidwa.

3. Ferrite pachimake ndi chitsulo ufa pachimake koyilo

Inductance ya koyilo imagwirizana ngati pali maginito pachimake kapena ayi. Kuyika pachimake cha ferrite mu koyilo yapakatikati kumatha kukulitsa inductance ndikuwongolera mtundu wa coil.

4, koyilo ya mkuwa

Copper core coil imagwiritsidwa ntchito kwambiri mu ultrashort wave range. Ndikosavuta komanso kolimba kusintha inductance pozungulira malo a mkuwa pachimake mu koyilo.

5, color code inductor

Inductor yokhala ndi utoto ndi inductance yokhala ndi inductance yokhazikika, ndipo inductance yake imadziwika ndi mphete yamtundu ngati chopinga.

6, kutsamwitsa koyilo (kutsamwitsa)

Koyilo yomwe imalepheretsa njira yosinthira magetsi imatchedwa choke coil, yomwe imatha kugawidwa kukhala koyilo yothamanga kwambiri komanso yotsika pafupipafupi.

7. Koyilo yopatuka

Deflection coil ndi katundu wa gawo lotulutsa la TV. Coil yopotoka imafunikira kukhudzidwa kwakukulu, mphamvu yamagetsi yofananira, mtengo wapamwamba wa Q, kukula kochepa komanso mtengo wotsika.

ntchito

Choka zochita

Mphamvu yodzipangira yokha ya electromotive mu coil ya inductance coil nthawi zonse imatsutsana ndi kusintha kwamakono kwa koyilo. Coil inductance imakhala ndi chotchinga pa AC pano, ndipo kukula kwa chotchinga kumatchedwa inductance xl, ndipo gawolo ndi ohm. Ubale wake ndi inductance L ndi AC pafupipafupi F ndi xl = 2πfl. Ma inductors amatha kugawidwa m'makoyilo afupipafupi kwambiri komanso ma coko otsika kwambiri.

Kusintha ndi kusankha pafupipafupi

Chigawo chowongolera cha lc chikhoza kupangidwa mwa kulumikiza coil inductance ndi capacitor mofanana. Ndiko kuti, ma frequency oscillation achilengedwe f0 a dera ndi ofanana ndi ma frequency f a siginecha yosagwirizana, kotero kuti inductive reactance ndi capacitive reactance ya dera ilinso yofanana, kotero mphamvu yamagetsi yamagetsi imayenda mmbuyo ndi mtsogolo mu inductance ndi capacitance, chomwe ndi chodabwitsa cha resonance ya lc circuit. Pa resonance, inductive reactance ndi capacitive reactance ya dera imakhala yofanana ndi yosiyana, ndipo kachitidwe kochititsa chidwi kamene kamakhala kakang'ono kwambiri ndipo kameneka ndi kakang'ono kwambiri (potengera chizindikiro cha AC ndi f = "F0"). lc resonant circuit ili ndi ntchito yosankha pafupipafupi, yomwe imatha kusankha chizindikiro cha AC ndi zina
