Kodi chigawo chosinthika cha inductor ndi chiyani?Opanga ma plug-in inductor amakudziwitsani.

Zomwe zimagwiritsidwa ntchito nthawi zambiri ndi ma coil oscillation omwe amagwiritsidwa ntchito mu ma radio semiconductor, ndi ma coil oscillation omwe amagwiritsidwa ntchito pa TV.

Ma coil ozungulira, ma coil apakati pafupipafupi, zolipira pafupipafupi zomvera, zotsekera zotsamwitsa, ndi zina zambiri za opanga zida za inductance

1. Koyilo ya oscillator yomwe imagwiritsidwa ntchito mu wailesi ya semiconductor: Koyilo ya oscillator iyi imagwiritsidwa ntchito mu wayilesi ya semiconductor kupanga dera la oscillator ladera lomwe lili ndi ma capacitor osinthika, ndi zina zambiri, zomwe zimagwiritsidwa ntchito popanga oscillation yakumalo komwe ndi 465kHz kuposa chizindikiro cha wayilesi cholandilidwa 器Signal.Lowetsani dera lokonzekera.Kunja kwake ndi chitsulo chotchinga chotchinga, ndipo mkati mwake chimapangidwa ndi nylon, maginito owoneka ngati I, chipewa cha maginito ndi mpando wa pini.Chingwe champhamvu champhamvu cha enameled chimagwiritsidwa ntchito pamtundu wa maginito wa I-mtundu.Chipewa cha maginito chimayikidwa pa bulaketi ya nayiloni mkati mwa chotchinga chotchinga, ndipo chimatha kuzunguliridwa mmwamba ndi pansi kuti chisinthire inductance ya koyilo posintha mtunda pakati pake ndi koyilo.Mapangidwe amkati a TV trap coil ndi ofanana ndi a coil oscillating, kupatula kuti chivundikiro cha maginito ndi maginito osinthika.

2. Mzere wokhotakhota wa seti ya TV: Mzere wokhotakhota umagwiritsidwa ntchito pa TV zoyambilira zakuda ndi zoyera.Amapanga kudzikonda oscillator dera (atatu mfundo oscillator kapena kutsekereza oscillator, multivibrator) ndi zotumphukira resistors ndi capacitors ndi mzere oscillation transistors, amene ntchito kupanga amakona anayi zimachitika voteji chizindikiro ndi pafupipafupi 15625HZ.

Bowo lalikulu, ikani koyilo yapakati ya koyilo yosinthira yolumikizira mwachindunji mu dzenje lalikulu.Chokhota chokhotakhota cholumikizira chimatha kusintha mtunda wapakati pakati pa pachimake ndi koyilo, potero kusintha koyilo ya inductance, kusunga ma frequency oscillation a mzere pa 15625 Hz ndi automatic The frequency control (AFC) imayenda molumikizana ndi kugunda kolumikizana komwe kumalowa. mzere wozungulira.

3. Koyilo ya mzere wa mzere: Koyilo ya mzere ndi mtundu wa koyilo yolumikizira maginito yopanda mzere (inductance yake imachepa ndi kuchuluka kwapano), nthawi zambiri imalumikizidwa motsatizana panjira yokhotakhota ya mzere, ndipo imagwiritsa ntchito mawonekedwe ake a maginito. kubwezera kupotozedwa kwa Linear kwa chithunzi.

Koyilo yofananira imapangidwa ndi bala la waya wa enameled pa "I"-wooneka ngati ferrite high-frequency magnetic core kapena ferrite magnetic rod, ndipo maginito osinthika amayikidwa pambali pa koyilo.Posintha malo wachibale wa maginito ndi koyilo kusintha kukula kwa koyilo inductance, kuti akwaniritse cholinga liniya chipukuta misozi.
