Kev ua haujlwm ntawm coil

1. Tam sim no-blocking nyhuv: Tus kheej-induced electromotive quab yuam nyob rau hauv inductor kauj ib txwm counteracts tam sim no hloov nyob rau hauv lub kauj.Lub inductance coil muaj qhov cuam tshuam ntawm AC tam sim no, thiab qhov loj ntawm cov nyhuv thaiv yog hu ua inductance xl, thiab chav tsev yog ohm.Nws txoj kev sib raug zoo nrog inductance L thiab AC zaus F yog xl = 2πfl.Inductors tuaj yeem muab faib ua ntau zaus choke coils thiab qis zaus choke coils.

2. Tuning thiab zaus xaiv: ib qho lc tuning Circuit Court tuaj yeem tsim los ntawm kev sib txuas ntawm inductance coil thiab capacitor nyob rau hauv parallel.Ntawd yog, lub ntuj oscillation zaus f0 ntawm Circuit Court yog sib npaug rau zaus f ntawm lub teeb liab tsis hloov, yog li qhov inductive reactance thiab capacitive reactance ntawm lub Circuit Court kuj sib npaug, yog li lub zog electromagnetic oscillates rov qab thiab tawm hauv inductance thiab capacitance, uas yog resonance tshwm sim ntawm lub lc circuit.Nyob rau hauv resonance, inductive reactance thiab capacitive reactance ntawm lub Circuit Court yog sib npaug thiab opposite.Lub inductance ntawm tag nrho cov tam sim no nyob rau hauv lub voj yog qhov tsawg tshaj plaws, thiab tam sim no yog qhov loj tshaj plaws (xa mus rau AC teeb liab nrog F = "F0").Lub lc resonant circuit muaj kev ua haujlwm ntawm kev xaiv zaus, uas tuaj yeem xaiv AC teeb liab nrog qee zaus F.

Raws li deb ntawm cov conductivity ntawm lub kauj yog kev txhawj xeeb, yog vim li cas tooj liab kauj yog zoo dua txhuas kauj?Ua ntej ntawm tag nrho cov, nyob rau hauv cov nqe lus ntawm conductivity, lub conductivity ntawm txhuas yog qis dua tooj liab.Txhawm rau khaws cov tooj liab coils, txhuas hlau nplaum hlau nplaum yuav xav tau ib ntu loj dua kom lawv tuaj yeem muab tib theem ntawm kev coj ua.Qhov ntawd yog hais tias, piv nrog cov tooj liab ntawm tib qhov loj, lub qhov txhab winding nrog txhuas hlau xav tau ntau dua ntim.

Thib ob, hais txog cov khoom siv tshuaj, oxidation tus nqi ntawm txhuas yog nrawm dua li ntawm lwm cov hlau.Yog tias cov hmoov txhuas raug huab cua, nws yuav raug oxidized tag nrho hauv ob peb hnub, tawm hauv cov hmoov dawb zoo.Yog li ntawd, txhawm rau ua kom muaj kev sib txuas kom zoo los xyuas kom muaj kev sib txuas zoo, nws yog qhov yuav tsum tau tho lub oxide txheej ntawm aluminium electromagnetic hlau los tiv thaiv kev sib cuag ntawm txhuas thiab cua.Thaum kawg, los ntawm qhov kev xav ntawm tus nqi-ua tau zoo, coil aluminium nrog tib qhov kev ua tau zoo xav tau ntau qhov kev hloov pauv thiab cov kab kab loj dua, uas yog kim dua thiab tsis tshua muaj nqi tshaj tooj liab.
