Cov xwm txheej yog dab tsi rauseries resonancetshwm sim? 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.
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 yuav ua kom muaj hluav taws xob siab ntawm inductors thiab capacitors uas muaj ntau zaus ntau dua li cov khoom siv hluav taws xob, yog li series resonance tseem hu ua voltage resonance.
Series resonancemuab faib ua zaus modulation thiab induction modulation. Nws feem ntau yog tsim los ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv, kev hloov pauv hloov hluav taws xob, reactor, thiab qhov hluav taws xob hluav taws xob faib hluav taws xob. Lub capacitor thiab reactor ntawm cov qauv kuaj ua ib tug series resonant kev twb kev txuas; Qhov hluav taws xob faib hluav taws xob txuas nrog rau qhov sib npaug rau cov qauv ntsuas los ntsuas qhov hluav taws xob resonant ntawm cov qauv ntsuas thiab muab cov teeb liab tiv thaiv overvoltage.
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 tsim 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 xeem. Nws tau txais txiaj ntsig zoo los ntawm cov kws tshaj lij thiab tau siv dav hauv tsev thiab txawv teb chaws.
Tam sim no, peb tau tsim ntau yam cuab yeej tshawb nrhiav siv lub hauv paus ntsiab lus ntawmseries resonance, suav nrog cov khoom siv hluav taws xob resonance test, cable sib txawv zaus series resonance test li, substation kuj tsis paub meej zaus series resonance test li, thiab resonant boost li rau CVT tshuaj xyuas.
Raws li lub hauv paus ntsiab lus ntawm resonance, peb paub tias thaum lub inductance tus nqi X1 ntawm lub tam sim no reactor L yog sib npaug zos rau tus nqi capacitance Xc nyob rau hauv Circuit Court, lub Circuit Court mus txog resonance xeev. Nyob rau lub sijhawm no, tsuas yog qhov kev tiv thaiv hluav taws xob R siv lub zog hluav taws xob hauv Circuit Court, thaum lub zog reactive oscillates rov qab los ntawm lub reactor thiab lub capacitor ntawm cov qauv kuaj, yog li tsim hluav taws xob siab ntawm cov qauv kuaj.
Cov xwm txheej rau series resonance tshwm sim:
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 zog engineering,series resonanceyuav tsum tau zam kom ntau li ntau tau, thiab series resonance kuaj cov cuab yeej tseem yuav raug siv los kuaj xyuas lub zog.
Qhov zoo ntawm series resonance
1. Lub zog yuav tsum tau txo qis heev. Lub series series series resonance xeem ntaus ntawv siv resonant reactors thiab lub capacitance ntawm cov khoom xeem los tsim resonance, yog li tau txais qhov yuav tsum tau high voltage thiab siab tam sim no. Nyob rau hauv tag nrho cov system, lub hwj chim mov tsuas yog yuav tsum tau muab lub active noj ib feem ntawm lub system. Yog li, qhov xav tau lub zog rau kev xeem tsuas yog 1 / Q lub sij hawm lub peev xwm xeem (Q yog qhov zoo tshaj).
2. Qhov hnyav thiab ntim ntawm cov khoom siv tau raug txo qis heev. Nyob rau hauv ib tug series resonant fais fab mov, tsis tsuas yog cov loj loj - fais fab voltage regulating ntaus ntawv thiab zoo tib yam high - fais fab zaus zaus transformer tshem tawm, tab sis lub resonant excitation fais fab mov tsuas yog yuav tsum tau 1/Q ntawm lub xeem muaj peev xwm, zoo heev txo lub cev nyhav thiab ntim, feem ntau yog 1/5-1/10 ntawm cov khoom siv zoo tib yam.
3. Txhim kho qhov tso zis voltage waveform. Lub resonant fais fab mov yog ib tug resonant filtering Circuit Court uas yuav txhim khu lub waveform distortion ntawm cov zis voltage, tau ib tug zoo sine yoj, thiab zoo tiv thaiv qhov tsis tseeb kev puas tsuaj ntawm cov qauv kuaj los ntawm harmonic peaks.
4. Tiv thaiv kom luv luv - cov hluav taws xob tam sim no los ntawm kev kub hnyiab qhov taw tes. Nyob rau hauv lub xeev resonant, thaum qhov tsis muaj zog ntawm rwb thaiv tsev ntawm cov qauv kuaj tau tawg, lub Circuit Court tam sim ntawd detuned (capacitance hloov, tsis ua raws li lub resonance mob), thiab lub Circuit Court tam sim no sai txo mus rau 1 / Q ntawm ib txwm kuaj tam sim no. Txawm li cas los xij, thaum siv cov kev sib txuas lus sib txuas lossis cov kev sim ntsuas ib txwm siv rau AC tiv thaiv qhov ntsuas hluav taws xob, qhov tawg tam sim no nce los ntawm kaum tawm zaus. Piv nrog rau ob, qhov luv luv -circuit tam sim no ntau pua zaus txawv ntawm qhov tam sim no tawg. Yog li, series resonance tuaj yeem txheeb xyuas qhov tsis muaj zog ntawm rwb thaiv tsev yam tsis muaj kev txhawj xeeb ntawm luv luv -circuit tam sim no hlawv qhov yuam kev.
5. Yuav tsis muaj overvoltage rov qab. Thaum cov qauv kuaj pom muaj kev puas tsuaj thiab flashover, vim qhov tsis zoo ntawm cov resonance tej yam kev mob, lub siab voltage tam sim ntawd ploj, lub arc yog tam sim ntawd tua, lub tiv thaiv Circuit Court ntawm lub ntaus ntawv yog qhib, thiab cov zis raug txiav tawm.
