Qhov sib txawv zaus series resonance withstand voltage test yog siv lub inductance ntawm lub reactor thiab lub capacitance ntawm cov khoom kuaj los ua ib tug LC series Circuit Court, kho qhov voltage zaus tso zis ntawm qhov sib txawv zaus zog mov, thiab ua tiav series resonance.
Raws li lub hauv paus ntsiab lus ntawm resonance, thaum qhov inductive reactance tus nqi X1 ntawm L reactor yog sib npaug rau lub capacitive reactance tus nqi XC hauv Circuit Court, Circuit Court yuav mus txog lub xeev resonance. Lub sijhawm no, tsuas yog qhov kev tiv thaiv hluav taws xob R tau siv lub zog ua haujlwm hauv Circuit Court, thaum lub zog reactive nyob rau hauv lub capacitance ntawm lub reactor thiab cov qauv kuaj, yog li tsim high voltage ntawm cov qauv kuaj.
Cov xwm txheej rau kev tsim cov resonance series: XL=XC
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 tag nrho cov txheej txheem.sib txawv zaus series resonance test khoomtxhawm rau txheeb xyuas qhov system fais fab.
Nyob rau hauv cov xwm txheej impedance, lub cim ntawm qhov xav txog qhov sib npaug tom qab resonance yog opposite. Lub impedance ntawm series yog sib npaug rau 0, thiab lub parallel impedance yog sib npaug rau infinity. Thaum resonance tshwm sim, 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 kev tiv thaiv thiab inductance, qhov tshwm sim ntawm lub hwj chim mov, voltage, thiab tam sim no nyob rau hauv tib theem yog hu uaseries resonance, uas yog tus cwj pwm los ntawm kev ua haujlwm dawb huv, kev siv hluav taws xob, qhov hluav taws xob, thiab tam sim no nyob rau tib theem. Lub reactance X yog sib npaug rau 0, thiab impedance Z yog sib npaug rau qhov tsis kam R. Lub sij hawm no, impedance ntawm lub Circuit Court yog qhov tsawg tshaj plaws, tam sim no yog qhov loj tshaj plaws, thiab inductance thiab capacitance yuav tsim voltages ntau zaus ntau dua li lub hwj chim mov voltage. Yog li ntawd, series resonance tseem hu ua voltage resonance. Parallel resonance: Nyob rau hauv ib tug resistor capacitor inductor parallel circuit, lub Circuit Court voltage thiab tag nrho tam sim no nyob rau hauv theem, uas yog hu ua parallel resonance. Nws cov yam ntxwv yog: thaum uas tig mus resonance yog ib tug tag nrho cov nyiaj them, lub hwj chim mov tsis tas yuav muab reactive zog, tsuas yog muab active zog xav tau los ntawm tus resistor. Thaum resonance tshwm sim, 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 ntawm Circuit Court, yog li thaum uas tig mus resonance kuj hu ua tam sim no resonance.
Nyob rau hauv ib tug series ntawm resistors, capacitor, thiab inductors, ncaj qha rho tawm ntawm inductors XL thiab XC; Yog tias qee qhov xwm txheej tau ua tiav, tsuas yog siv XL=Xc, qhov reactance ntawm lub Circuit Court yog sib npaug rau xoom, tam sim no thiab voltage theem hauv Circuit Court yog tib yam, thiab lub zog reactive tsis pauv ntawm cov resistors, inductors, thiab capacitors. Lub xeev ntawm Circuit Court hu uaseries resonance.
Hauv AC Circuit Court nrog resistor R, inductor L, thiab capacitor C, qhov hluav taws xob thoob plaws hauv Circuit Court feem ntau txawv ntawm theem tam sim no. Yog tias peb kho qhov tsis sib xws lossis lub zog zaus ntawm cov khoom siv hluav taws xob (L lossis C), lawv tuaj yeem nyob hauv tib theem, thiab tag nrho cov hluav taws xob hluav taws xob yog qhov tsis muaj zog. Thaum lub voj voog mus txog lub xeev no, nws hu ua resonance.
Nyob rau hauv ib tug series Circuit Court muaj li ntawm resistors, inductors, thiab capacitors, thaum capacitor XC =inductor XL yog sib npaug, series resonance tshwm sim, thiab theem ntawm voltage U thiab tam sim no kuv nyob rau hauv lub Circuit Court yog tib yam; Thaum ib tug series resonance tshwm sim nyob rau hauv lub Circuit Court, lub impedance Z=R2+XC-XL2=R, tag nrho impedance ntawm lub Circuit Court yog txo, 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 ntawm ob kawg ntawm lub Circuit Court feem ntau txawv; Yog tias qhov ntsuas qhov tseem ceeb ntawm cov khoom siv hluav taws xob hloov pauv lossis qhov zaus ntawm cov khoom siv hluav taws xob tau hloov kho, qhov voltage thiab tam sim no ntawm Circuit Court yuav nyob rau theem, thiab impedance ntawm lub Circuit Court yuav tso saib cov khoom ntawm kev tiv thaiv. Hom Circuit Court no hu ua resonance. Raws li cov ntaub ntawv sib txawv ntawm kev sib txuas ntawm lub voj voog, qhov tshwm sim resonance tuaj yeem muab faib ua series resonance thiab parallel resonance. Nyob rau hauv R, l, C series Circuit Court, thaum XL=XC, lub impedance lub kaum sab xis ∧=0, uas yog, lub hwj chim mov voltage thiab tam sim no nyob rau hauv theem. Qhov no tshwm sim yog hu ua series resonance. Cov yam ntxwv ntawm series resonance yog tias thaum resonance tshwm sim, vim qhov inductance XL yog sib npaug rau XC, qhov impedance ncav cuag nws qhov tsawg kawg nkaus thiab qhov kev tiv thaiv Circuit Court yog tsawg.
Thaum qhov voltage U tsis tas li, tam sim no kuv nyob hauv Circuit Court mus txog nws qhov siab tshaj plaws. Vim lub resonance XL=XC, theem ntawm UL=UC yog opposite rau UL thiab UC, yog li qhov voltage ntawm tus resistor yog sib npaug zos rau lub hwj chim mov voltage. Series Circuit Court resonance muaj qee yam ntxwv. Kev nkag siab txog qhov tshwm sim resonance tuaj yeem siv cov yam ntxwv no los tiv thaiv kev puas tsuaj los ntawm qee yam yam ntxwv. Harmonic filtering li siv cov yam ntxwv ntawm series resonance los xav txog lub ntsiab harmonic. General reactive fais fab nyiaj them nyiaj pab kiag li lawm yuav tsum zam series resonance vim hais tias thaum series resonance tshwm sim, qhov voltage ntawm lub capacitor Cheebtsam yuav nce, uas yuav ua rau puas lub capacitor rwb thaiv tsev txheej. Txawm li cas los xij, hauv xov tooj cua engineering, cov teeb liab uas yuav tsum tau txais tuaj yeem muab rho tawm los ntawm kev xaiv ntawm series resonance tshwm sim thiab qhov tau txais high voltage. Qhov zoo tshaj plaws Q ntawm LC zaus xaiv resonant Circuit Court yog txhais raws li: Qo=wo L/R, wo yog lub resonant zaus ntawm Circuit Court, thiab R yog inductance tsis kam L.
