Ntchito ya coil

1. Kutsekereza kwamakono: Mphamvu yodzipangira yokha ya electromotive mu coil inductor 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.

2. Kusintha ndi kusankha pafupipafupi: lc tuning circuit ikhoza 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 ndizofanana komanso zotsutsana. Inductance ya chiwerengero chonse mu chipika ndi yaying'ono kwambiri, ndipo panopa ndi yaikulu (ponena za chizindikiro cha AC ndi F = "F0"). Dera la lc resonant lili ndi ntchito yosankha pafupipafupi, yomwe imatha kusankha chizindikiro cha AC ndi ma frequency F.

Ponena za momwe koyiloyo imakhudzidwira, chifukwa chiyani koyilo yamkuwa ili bwino kuposa koyilo ya aluminiyamu? Choyamba, ponena za conductivity, madulidwe a aluminiyamu ndi otsika kuposa mkuwa. Kuti mukhale ndi coils zamkuwa, mawaya a aluminiyamu maginito angafunike gawo lalikulu la mtanda kuti athe kupereka mulingo womwewo wa conductivity. Izi zikutanthauza kuti, poyerekeza ndi koyilo yamkuwa yofanana kukula kwake, bala lopindika lomwe lili ndi waya wa aluminiyamu limafunikira voliyumu yochulukirapo.

Kachiwiri, pankhani yamankhwala, kuchuluka kwa okosijeni kwa aluminiyamu kumathamanga kwambiri kuposa zitsulo zina. Ngati ufa wa aluminiyumu ukuwonekera ku mpweya, udzakhala wodzaza ndi okosijeni m'masiku ochepa chabe, ndikusiya ufa wabwino woyera. Chifukwa chake, kuti mulumikizane bwino kuti mutsimikizire kuyendetsa bwino, ndikofunikira kuboola chingwe cha oxide cha aluminiyamu yama electromagnetic waya kuti mupewe kulumikizana kwina pakati pa aluminiyumu ndi mpweya. Pomaliza, potengera kutsika mtengo, aluminiyamu ya koyilo yokhala ndi magwiridwe antchito ofanana imafunikira makhothi ochulukirapo komanso mawaya okulirapo, omwe ndi okwera mtengo komanso otsika mtengo kuposa koyilo yamkuwa.
