Cov xwm txheej yog dab tsi rauseries resonance? Wuhan UHV tshwj xeeb hauv kev tsim khoomseries resonance, nrog ntau yam khoom xaiv thiab kev kuaj hluav taws xob. Nrhiavseries resonance, xaiv Wuhan UHV.
Lub series resonance withstand voltage test yog ib txoj kev tshiab ntawm high voltage xeem uas siv lub inductance ntawm ib tug reactor thiab lub capacitance ntawm lub xeem khoom los ua ib tug LC series Circuit Court, kho qhov voltage zaus tso zis ntawm qhov sib txawv zaus fais fab mov, ua tiav.series resonance, thiab tau txais high voltage ntawm cov khoom kuaj. 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 yog lub high voltage generated los ntawm series resonance nyob rau hauv L thiab C, nws yuav ua rau puas ntsoog 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 rau sivseries resonance kuaj cov cuab yeejtxhawm rau txheeb xyuas cov tshuab hluav taws xob.
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 resonance tseem 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.
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.
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
Nyob rau hauv AC Circuit Court nrog resistor R, inductor L, thiab capacitor C Cheebtsam, qhov voltage ntawm ob 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 tib 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 lub voj voog uas muaj cov resistors, inductors, thiab capacitors, series resonance tshwm 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 lub sinusoidal AC Circuit Court nrog R, L, thiab C Cheebtsam, qhov voltage thiab tam sim no ntawm ob 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 impedance ntawm lub Circuit Court kom muaj zog tiv taus. Ib lub voj voog nyob rau hauv lub xeev no hu ua resonance Raws li cov ntaub ntawv sib txawv ntawm circuits, resonance phenomena tuaj yeem muab faib uaseries resonancethiab 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, qhov tshwm sim no hu ua series resonance Tus yam ntxwv ntawm series resonance: Thaum resonance tshwm sim, lub impedance mus txog nws yam tsawg kawg nkaus tus nqi vim lub XL. sib npaug ntawm lub capacitance XC, ua rau muaj kev tiv thaiv hluav taws xob.
Thaum qhov voltage U tseem nyob tas li, tam sim no kuv nyob rau hauv Circuit Court mus txog nws qhov siab tshaj plaws txij li XL=XC thaum lub sij hawm resonance, UL=UC, thiab UL thiab Uc muaj cov theem tsis sib xws, lawv rho tawm ib leeg tawm thaum ntxiv ua ke, yog li qhov voltage ntawm tus resistor yog sib npaug rau lub hwj huam mov voltage Thaum ib tug series Circuit Court resonates, nws muaj tej yam ntxwv. Nkag siab txog qhov tshwm sim resonance tuaj yeem siv cov yam ntxwv no thiab tiv thaiv kev puas tsuaj los ntawm qee yam yam ntxwv Lub LC harmonic filtering ntaus ntawv siv cov yam ntxwv ntawm cov resonance series cais tawm cov kev sib raug zoo hauv cov khoom siv hluav taws xob zoo tib yam,series resonanceyuav tsum tau zam vim hais tias thaum series resonance tshwm sim, qhov voltage ntawm lub capacitor caij yuav nce, uas tej zaum yuav ua rau lub rwb thaiv tsev txheej ntawm lub capacitor yuav tawg tab sis nyob rau hauv lub xov tooj cua engineering, lub selectivity ntawm series resonance tshwm sim thiab cov tau ntau dua voltage yuav siv tau los rho tawm cov teeb liab uas yuav tsum tau txais qhia qhov zoo tshaj plaws Q nyob rau hauv LC zaus xaiv resonant Circuit Court, uas yog txhais raws li ib tug ntau yam ntawm resonance. Qo=WoL/r, qhov twg Wo yog qhov resonant zaus ntawm Circuit Court thiab r yog qhov noj tsis kam ntawm inductance L.
