Umsebenzi wekhoyili

1. Impembelelo yangoku yokuthintela: I-self-induced force electromotive kwi-coil inductor isoloko iphikisana noshintsho lwangoku kwikhoyili.I-coil inductance inefuthe lokuthintela kwi-AC yangoku, kwaye ubungakanani besiphumo sokuthintela kuthiwa yi-inductance xl, kwaye iyunithi i-ohm.Ubudlelwane bayo kunye ne-inductance L kunye ne-AC frequency F yi-xl = 2πfl.Ii-inductors zinokwahlulwa ikakhulu zibe ziikhoyili zokukrwitsha ezikwi-frequency high-frequency coil coil kunye ne-low-frequency coke coil.

2. I-Tuning kunye nokukhethwa kwama-frequency: i-lc tuning circuit inokuqulunqwa ngokudibanisa i-coil inductance kunye ne-capacitor ngokufanayo.Oko kukuthi, i-frequency yendalo ye-oscillation f0 yesekethe ilingana ne-frequency f ye-non-alternating signal, ngoko ke i-inductive reactance kunye ne-capacitive reactance ye-circuit nazo ziyalingana, ngoko ke amandla ombane we-electromagnetic oscillates abuyele emva naphambili kwi-inductance kwaye i-capacitance, eyona nto i-resonance phenomenon yesekethe ye-lc.Kwi-resonance, i-inductive reactance kunye ne-capacitive reactance yesekethe iyalingana kwaye ichasene.I-inductance ye-current yangoku kwi-loop iyona nto incinci, kwaye yangoku iyona inkulu (ibhekisela kwisignali ye-AC kunye ne-F = "F0").Isekethe ye-lc resonant inomsebenzi wokukhetha rhoqo, enokukhetha isignali ye-AC kunye nefrikhwensi ethile yeF.

Ngokubhekiselele kwi-conductivity yekhoyili, kutheni i-coil yobhedu ingcono kune-coil ye-aluminium?Okokuqala, ngokubhekiselele kwi-conductivity, i-conductivity ye-aluminium iphantsi kunobhedu.Ukuze ugcine iikhoyili zobhedu, iingcingo ze-aluminium magnetic zingadinga icandelo elikhulu lomnqamlezo ukuze bakwazi ukubonelela ngenqanaba elifanayo lokuqhuba.Oko kukuthi, xa kuthelekiswa nekhoyili yobhedu yobukhulu obufanayo, inxeba elijikajikayo elinocingo lwe-aluminiyam lifuna umthamo ongakumbi.

Okwesibini, ngokweempawu zeekhemikhali, izinga le-oxidation ye-aluminiyam likhawuleza kakhulu kunezinye isinyithi.Ukuba i-aluminium powder ibonakaliswe emoyeni, iya kuba yi-oxidized ngokupheleleyo kwiintsuku nje ezimbalwa, ishiya umgubo omhlophe ococekileyo.Ke ngoko, ukuze wenze uqhagamshelo olululo ukuqinisekisa ukusebenza kakuhle, kuyafuneka ukuba ugqobhoze umaleko we-oxide we-aluminium yombane we-electromagnetic wire ukuthintela ukunxibelelana ngakumbi phakathi kwe-aluminiyam nomoya.Ekugqibeleni, kwimbono yeendleko-ukusebenza, i-aluminium ye-coil kunye nokusebenza okufanayo idinga ukujika okungaphezulu kunye neengcingo ezinkulu ze-diameter, ezibiza kakhulu kwaye zingaphantsi kwezoqoqosho kunekhoyili yobhedu.
