Yintoni icandelo le-inductor elihlengahlengiswayo? Abavelisi be-plug-in inductor bazisa kuwe.

Amacandelo e-inductor asetyenziswa ngokuqhelekileyo asetyenziswa kwiikhoyili ze-oscillation ezisetyenziswa kwiirediyo ze-semiconductor, kunye neekhoyili ze-oscillation zomgca ezisetyenziswa kumabonakude.

Iikhoyili ezilayini, iikhoyili ze-intermediate frequency trap, iikhoyili zembuyekezo ye-audio frequency, iikhoyili eziminxayo, njl.

1. I-coil ye-oscillator esetyenziswe kwirediyo ye-semiconductor: Le coil ye-oscillator isetyenziswe kwirediyo ye-semiconductor ukwenza isiphaluka se-oscillator yendawo kunye ne-variable capacitors, njl., esetyenziselwa ukuvelisa i-oscillation yendawo eyi-465kHz ephezulu kunesignali yerediyo efunyenweyo 器Signal. Ngena kwisekethe yokulungisa. Umphandle ngumaleko okhuselayo wesinyithi, kwaye ngaphakathi yenziwe ngelayini yenayiloni, undoqo wemagnethi omile okwe-I, icap magnetic kunye nesitulo sephini. I-high-power enameled wire winding isetyenziswa kwi-I-type magnetic core. I-cap yamagnetic ifakwe kwi-nylon bracket ngaphakathi kwe-shielding layer, kwaye inokujikelezwa phezulu nangaphantsi ukuze itshintshe i-inductance yekhoyili ngokuguqula umgama phakathi kwayo kunye nekhoyili. Isakhiwo sangaphakathi se-coil yomgibe we-TV ifana neyo-coil e-oscillating, ngaphandle kokuba isigqubuthelo sombane singundoqo oguquguqukayo wemagnethi.

2. Ikhoyili ejikajikayo yomgca weseti yeTV: Ikhoyili yomgca oscillating isetyenziswa kwiiseti zikamabonakude zakuqala ezimnyama namhlophe. Yenza i-self-excited oscillator circuit (i-oscillator yamanqaku amathathu okanye i-oscillator yokuvimbela, i-multivibrator) kunye ne-resistors ye-peripheral kunye ne-capacitors kunye ne-transistors ye-oscillation yomgca, esetyenziselwa ukuvelisa i-rectangular pulse voltage signal kunye ne-frequency ye-15625HZ.

Umngxuma wesikwere, faka i-core coil ye-coil ye-synchronization adjustment knob ngqo kumngxuma wesikwere. Iqhoshana lohlengahlengiso lokulungelelaniswa kwesibini elijijekileyo linokutshintsha umgama ohambelanayo phakathi kombindi kunye nekhoyili, ngaloo ndlela itshintsha ikhoyili ye-inductance, igcina i-oscillation frequency yomgca kwi-15625 Hz kunye ngokuzenzekelayo Ulawulo lwamaza (AFC) oscillates ngaxeshanye kunye nepulse yokuvumelanisa engena. umgca wesekethe.

3. Ikhoyili yomgca welayini: Ikhoyili yomgca luhlobo lwekhoyili ye-non-linear magnetic saturation inductance (i-inductance yayo iyancipha ngokunyuka kwangoku), idityaniswe ngokubanzi kuluhlu kwi-coil loop ye-deflection coil, kwaye isebenzisa iimpawu zayo zokuzalisa magnetic. ukuhlawula ukugqwetheka koMgama kumfanekiso.

Ikhoyili yomgca yenziwe ngenxeba locingo lwe-enameled kwi-"I"-shaped ferrite high-frequency magnetic core okanye ferrite rod magnetic, kunye nemagnethi ehlengahlengiswayo ifakwe ecaleni kwekhoyili. Ngokutshintsha indawo ehambelanayo yemagnethi kunye nekhoyili ukutshintsha ubungakanani be-coil inductance, ukuze kuphunyezwe injongo yembuyekezo yomgca.
