Nyob rau hauv ib lub voj voog uas cov resistors, capacitors, thiab inductors txuas nrog hauv koob, lub luag haujlwm ntawm inductive reactance Xl thiab Xc raug rho tawm ncaj qha. Yog tias qee qhov xwm txheej tau ua tiav, xws li Xl=Xc, qhov reactance ntawm lub Circuit Court yog sib npaug rau xoom, tam sim no thiab voltage theem nyob rau hauv Circuit Court yog tib yam, thiab tsis muaj reactive hwj chim pauv ntawm tus resistor, inductor, los yog capacitor. Lub xeev ntawm Circuit Court hu uaseries resonance.
Covseries resonancewithstand voltage test yog ib txoj kev tshiab ntawm high voltage xeem uas siv lub inductance ntawm lub reactor thiab lub capacitance ntawm cov khoom xeem los tsim ib tug LC series Circuit Court, kho qhov voltage zaus tso zis ntawm qhov sib txawv zaus zog mov, ua tiav series resonance, thiab tau txais high voltage ntawm cov khoom xeem. Nws tau txais txiaj ntsig zoo los ntawm cov kws tshaj lij thiab tau siv dav hauv tsev thiab txawv teb chaws.
Cov xwm txheej rau kev tsimseries resonance:
X L =X C
Vim lub high voltage generated los ntawmseries resonancenyob rau hauv L thiab C, nws yuav ua rau kev puas tsuaj ntawm coils los yog capacitors. Yog li ntawd, nyob rau hauv lub hwj chim engineering, series resonance yuav tsum tau zam kom ntau li ntau tau, thiab nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum tau siv series resonance kuaj cov cuab yeej los xyuas cov tshuab fais fab.
Thaum lub sij hawm resonance, lub resonant tam sim no ntawm series Circuit Court yog infinite; Lub resonant voltage ntawm ib tug parallel Circuit Court yog infinite (tus nqi theoretical). Nyob rau hauv ib tug series ntawm resistors thiab inductors, qhov tshwm sim ntawm lub hwj chim mov, voltage, thiab tam sim no nyob rau hauv theem yog hu ua series resonance. Nws cov yam ntxwv yog: lub Circuit Court yog purely resistive, lub hwj chim mov, voltage, thiab tam sim no nyob rau hauv theem, lub reactance X yog sib npaug zos rau 0, thiab impedance Z yog sib npaug zos R. Nyob rau lub sij hawm no, lub impedance ntawm lub Circuit Court yog tsawg tshaj plaws, tam sim no yog qhov loj tshaj plaws, thiab high voltages ntau zaus siab tshaj lub hwj chim mov voltage tej zaum yuav generated ntawm inductance thiab capacitance. Yog li ntawd,series resonancetseem hu ua voltage resonance.
Lub resonance voltage yog superimposed nrog tus thawj voltage, thiab parallel resonance: nyob rau hauv parallel circuits ntawm resistors, capacitors, thiab inductors, qhov tshwm sim ntawm lub Circuit Court terminal voltage thiab tag nrho tam sim no nyob rau hauv theem yog hu ua parallel resonance. Nws cov yam ntxwv yog tias thaum uas tig mus resonance yog ib tug ua tiav cov nyiaj them, thiab lub hwj chim mov tsis tas yuav muab reactive hwj chim, tsuas yog lub active zog yuav tsum tau los ntawm lub resistor. Thaum lub sij hawm resonance, tag nrho cov tam sim no ntawm lub Circuit Court yog tsawg, thiab cov ceg tam sim no feem ntau ntau dua li tag nrho cov tam sim no hauv Circuit Court. Yog li ntawd, parallel resonance tseem hu ua tam sim no resonance.
Lub resonance mob ntawm lub Circuit Court yog Xc=Xl, uas yog, ω L=1/ω C, los ntawm qhov inherent resonance mob ntawm lub circuit yuav tau raws li f0=1/(2 π√ LC). Qhov xwm txheej impedance: Tom qab resonance, qhov xav txog qhov sib npaug ntawm kos npe thiab rov qab rau hauv kos npe. Lub impedance ntawm series yog sib npaug rau 0, thiab lub parallel impedance yog sib npaug rau infinity. Ntawm resonance, lub resonant tam sim no ntawm lub series Circuit Court yog infinite; Lub resonant voltage ntawm ib tug parallel Circuit Court yog infinite (tus nqi theoretical). Los yog ua lwm yam lus:
(1) Nyob rau hauv ib tug series Circuit Court, lub tswv yim ib feem ntawm tag nrho cov input impedance yog sib npaug zos rau xoom (resonance yog hais txog cov zis voltage thiab tam sim no nyob rau hauv theem)
(2) Nyob rau hauv parallel circuits, qhov xav txog ib feem ntawm tag nrho cov input nkag yog xoom
Hauv AC Circuit Court nrog resistor R, inductor L, thiab capacitor C Cheebtsam, qhov voltage ntawm ob qhov kawg ntawm lub Circuit Court yog feem ntau sib txawv nyob rau hauv theem ntawm tam sim no nyob rau hauv nws. Yog tias peb kho qhov tsis sib xws lossis lub zog zaus ntawm cov khoom siv hluav taws xob (L lossis C), peb tuaj yeem ua rau lawv cov theem zoo ib yam, thiab tag nrho cov Circuit Court zoo nkaus li tiv taus. Thaum lub voj voog mus txog lub xeev no, nws hu ua resonance.
Nyob rau hauv ib tug series ntawm Circuit Court muaj xws li resistors, inductors, thiab capacitor,series resonancetshwm sim thaum lub capacitance reactance XC=inductance reactance XL yog sib npaug, thiab theem ntawm qhov voltage U thiab tam sim no I hauv Circuit Court yog tib yam. Thaum ib tug series resonance tshwm sim nyob rau hauv ib tug Circuit Court, lub impedance ntawm lub Circuit Court Z=√ R2+XC-XL2=R, tag nrho impedance nyob rau hauv Circuit Court yog tsawg tshaj plaws, thiab tam sim no yuav ncav cuag nws qhov siab tshaj plaws tus nqi.
Nyob rau hauv ib tug sinusoidal AC Circuit Court nrog R, L, thiab C Cheebtsam, qhov voltage thiab tam sim no nyob rau hauv ob hnub kawg ntawm lub Circuit Court yog feem ntau sib txawv theem Yog hais tias tus parameter qhov tseem ceeb ntawm Circuit Court Cheebtsam raug hloov los yog zaus ntawm lub hwj huam mov hloov, qhov voltage thiab tam sim no ntawm lub Circuit Court yuav nyob rau theem, ua rau lub impedance ntawm lub Circuit Court kom muaj zog kuj. Ib lub voj voog nyob rau hauv lub xeev no hu ua resonance Raws li cov kev sib txuas sib txawv ntawm circuits, resonance tshwm sim tuaj yeem muab faib ua series resonance thiab parallel resonance Nyob rau hauv ib tug series ntawm R, L, thiab C, thaum XL=XC nyob rau hauv lub Circuit Court, lub impedance lub kaum sab xis ∧=0, uas yog, lub hwj chim mov voltage thiab tam sim no nyob rau hauv theem no yog hu ua no.series resonanceCov yam ntxwv ntawm series resonance: Thaum resonance tshwm sim, lub impedance ncav cuag nws qhov tsawg kawg nkaus tus nqi vim inductance XL yog sib npaug rau lub capacitance XC, uas ua rau ib tug resistive circuit.
