Karolo ea inductor e feto-fetohang ke eng? Baetsi ba li-plug-in inductor ba u tsebisa.

Likarolo tsa li-inductor tse sebelisoang ka tloaelo ke li-coil tsa oscillation tse sebelisoang liea-le-moeeng tsa semiconductor, le likhoele tsa oscillation tse sebelisoang lithelevisheneng.

Likhoele tsa linear, li-trap coil tsa intermediate frequency trap coil, audio frequency coil, choke coil, joalo-joalo tsa baetsi ba likarolo tsa inductance

1. Coil ea oscillator e sebelisoang seea-le-moeeng sa semiconductor: Coil ena ea oscillator e sebelisoa seea-le-moeeng sa semiconductor ho etsa potoloho ea oscillator ea sebakeng seo e nang le li-capacitor tse feto-fetohang, joalo-joalo, e sebelisetsoang ho hlahisa oscillation ea sebakeng seo e leng 465kHz holimo ho feta letšoao la seea-le-moea le amoheloang 器Signal. Kenya potoloho ea tokiso. Ka ntle ke lera le sireletsang tšepe, 'me ka hare ho na le lesela la nylon, mokokotlo oa makenete oa sebopeho sa I, cap cap le setulo sa phini. Ho sebelisoa terata e nang le terata e nang le matla a phahameng holim'a mokokotlo oa makenete oa mofuta oa I. Sekoahelo sa makenete se kenngoa ka har'a bracket ea nylon ka har'a lesela le sireletsang, 'me se ka fetoloa holimo le tlase ho fetola inductance ea coil ka ho fetola sebaka se pakeng tsa eona le khoele. Sebopeho sa ka hare sa sefi sa TV se tšoana le sa coil e oscillating, ntle le hore sekoahelo sa makenete ke mokokotlo o feto-fetohang oa makenete.

2. Khoele e oscillating ea sete ea TV: Khoele e oscillating e sebelisoa li-TV tsa pele tse ntšo le tse tšoeu. E theha potoloho ea oscillator e ithabisang (lintlha tse tharo tsa oscillator kapa oscillator e thibelang, multivibrator) e nang le li-resistors tsa peripheral le capacitor le line oscillation transistors, e sebelisetsoang ho hlahisa lets'oao la motlakase oa li-rectangular pulse voltage le frequency ea 15625HZ.

Sekoti se sekoti, kenya khoele ea mantlha ea kotola ea tokiso ea khokahano ka kotloloho mokoting oa lisekoere. Konopo ea phetoho ea li-synchronization tse sothehileng e ka fetola sebaka se lekanyelitsoeng lipakeng tsa mantlha le coil, ka hona e fetola coil ea inductance, e boloka maqhubu a oscillation a mohala ho 15625 Hz le oscillation ea "frequency control" (AFC) oscillates ka mokhoa o ts'oanang le pulse ea khokahano e kenang. mohala oa potoloho.

3. Khoeli ea linear: Khoele ea linear ke mofuta oa khoele e sa tsitsang ea matla a khoheli (inductance ea eona e ea fokotseha ka keketseho ea hajoale), hangata e hokahanngoa ka letoto la khoele ea khoele ea ho kheloha, 'me e sebelisa litšobotsi tsa eona tsa matla a khoheli. ho lefella ho sotha ha setšoantšo ka Linear.

Mohala oa mohala o entsoe ka leqeba la terata e nang le enameled holim'a "I"-shaped ferrite high-frequency magnetic core kapa ferrite magnetic rod, 'me makenete e feto-fetohang e kenngoa ka thōko ho coil. Ka ho fetola boemo bo lekanyelitsoeng ba makenete le khoele ho fetola boholo ba inductance ea coil, e le ho fihlela sepheo sa mats'eliso a mela.
