Dab tsi yog qhov phom sij ntawmseries 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.
Series resonanceSiv cov resonant reactors thiab cov capacitance resonance ntawm cov qauv xeem los tsim cov high voltage thiab high tam sim no, uas yog dav siv rau lub handover thiab tiv thaiv kev ntsuam xyuas ntawm loj muaj peev xwm, siab -voltage capacitive tests xws li fais fab cables, fais fab mov transformers, generator sets, motors, switchgear, GIS keyboards, thiab lwm yam tab sis muaj ib tug muaj kev ruaj ntseg cov ntaub ntawv. kuaj. Yog li, dab tsi yog qhov txaus ntshai ntawmseries resonance? Hauv qab no, peb yuav piav qhia txog kev phom sij ntawm cov resonance raws li kev ua haujlwm tau zoo.
1. Cov xwm txheej tshwm sim los ntawm series resonance
Nyob rau hauv ib tug series Circuit Court muaj li ntawm resistors, inductors, thiab capacitors, thaum lub capacitance reactance XC =inductance reactance XL yog sib npaug, series resonance tshwm sim, thiab theem ntawm voltage U thiab tam sim no I nyob rau hauv lub 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. Qhov no tuaj yeem tsim cov hluav taws xob siab ntawm inductors thiab capacitors uas muaj ntau zaus siab dua qhov hluav taws xob hluav taws xob hluav taws xob, ua rau cov khoom siv hluav taws xob puas tsuaj thiab cuam tshuam rau kev nyab xeeb ntawm daim phiaj hluav taws xob kom raug kho qhov hluav taws xob tsis zoo R, L, thiab C tuaj yeem zam.series resonance.
2. Ntsuas cov yam ntxwv ntawm series resonant circuits
Qhov zoo tshaj plaws yog ib qho tseem ceeb parameter rau kev ntsuas cov yam ntxwv ntawm resonant circuits. Qhov loj dua qhov reactance thiab qhov me me qhov tsis kam nyob rau hauv ib lub voj voog, qhov zoo dua qhov zoo. Yog li ntawd, tus nqi hluav taws xob ntawm lub capacitor lossis inductor yuav ntau dua li qhov siv hluav taws xob. Qhov zoo tshaj qhov tseem ceeb ntawm cov inductor thiab capacitor resonant circuits tuaj yeem ncav cuag kaum lossis ntau pua. Qhov teeb meem ntawm resonant overvoltage yog txiav txim tsis tsuas yog los ntawm nws amplitude, tab sis kuj los ntawm lub sij hawm. Nyob rau hauv lub hwj chim system, series resonance yuav tsim overvoltage ob peb zaug siab tshaj qhov ntsuas voltage ntawm daim phiaj. Ua rau muaj teeb meem loj rau kev ua haujlwm nyab xeeb ntawm cov khoom siv hluav taws xob.
Nyob rau hauv xyoo tas los no, muaj ntau yam teeb meem ntawm transformer puas tsuaj nyob rau hauv feem ntau ntawm lub teb chaws, feem ntau yog vim li cas tsim thiab tsim, nrog rau qee qhov xwm txheej ntawm ferromagnetic resonance tshwm sim los ntawm kev ua haujlwm tsis raug, ua rau PT tawg. Kev tshuaj xyuas kev ua haujlwm qhia tau hais tias ua ntej tsim daim phiaj hluav taws xob, qee cov phau ntawv qub thiab kev npaj yuav tsum tau ua kom tsis txhob muaj kev puas tsuaj los ntawmseries resonancelos yog luv luv lub sij hawm ntawm resonance ntau npaum li sai tau.
