Dab tsi yog qhov resonance tej yam kev mob ntawm RLC series Circuit Court? Wuhan UHV tshwj xeeb hauv kev tsim khoomseries resonant khoom siv, nrog ntau yam khoom xaiv thiab kev kuaj hluav taws xob. Thaum nrhiav series resonant li, xaiv Wuhan UHV.
1, Txheej txheem cej luam ntawm cov yam ntxwv ntawmSeries Resonance thiab Parallel Resonance
Qhov sib txawv zaus series resonance xeem ntaus ntawv, tseem hu ua series resonance, yog tsim los ntawm ib tug sib txawv zaus zog mov, excitation transformer, reactor, thiab capacitive voltage divider. Lub capacitor thiab reactor ntawm cov qauv kuaj ua ib tug series resonant kev twb kev txuas; Lub qhov hluav taws xob faib hluav taws xob txuas nrog rau qhov sib npaug ntawm cov qauv ntsuas los ntsuas qhov hluav taws xob resonant ntawm cov qauv ntsuas thiab muab lub teeb liab tiv thaiv overvoltage; Lub zaus hloov hluav taws xob tso zis yog ua ke rau cov kab hluav taws xob resonant los ntawm kev hloov pauv excitation, muab lub zog excitation rau series resonance.
Nyob rau hauv ib lub voj voog uas inductors thiab capacitors txuas nyob rau hauv parallel, thaum qhov luaj li cas ntawm lub capacitor precisely ua rau lub voltage thiab tam sim no nyob rau hauv Circuit Court nyob rau hauv theem, uas yog, thaum tag nrho cov fais fab mov lub zog yog siv los ntawm lub resistor thiab ua ib tug resistor Circuit Court, nws yog hu ua parallel resonance. Parallel resonance yog ib qho kev them nyiaj tiav, qhov twg lub hwj chim mov tsis tas yuav muab lub zog reactive, tsuas yog lub zog nquag xav tau los ntawm tus resistor.
Thaum lub sij hawm resonance, tag nrho cov tam sim no ntawm lub Circuit Court yog tsawg, thaum lub sij hawm tam sim no ntawm cov ceg feem ntau ntau dua li tag nrho tam sim no ntawm Circuit Court. Yog li ntawd, parallel resonance tseem hu ua tam sim no resonance. Thaum lub sij hawm resonance tshwm sim, ib tug loj tam sim no ntws los ntawm inductive thiab capacitive Cheebtsam, uas yuav ua rau muaj kev huam yuaj xws li Circuit Court fuses melting los yog hlawv cov khoom hluav taws xob; Tab sis hauv xov tooj cua engineering, nws feem ntau yog siv los xaiv cov teeb liab thiab tshem tawm kev cuam tshuam.
2, Circuit Court yam ntxwv ntawm series resonance thiab parallel resonance
Cov yam ntxwv ntawm Circuit Court resonance
1. Yam tsawg kawg nkaus tus nqi impedance: Z=R+j (wl-1/wc)=R;
2. Thaum lub hwj chim mov voltage yog tas li, tam sim no nyob rau ntawm nws qhov siab tshaj plaws; I=I0=U/|Z|=U/R;
3. Lub Circuit Court yog resistive, thiab qhov voltage ntawm lub capacitor los yog inductor tej zaum yuav siab tshaj lub hwj chim mov voltage.
Cov yam ntxwv ntawm Parallel Resonance Circuit
1. Thaum qhov hluav taws xob tas li, qhov tam sim no raug txo qis thaum lub sij hawm resonance;
2. Qhov siab tshaj plaws impedance;
3. Lub Circuit Court yog resistive, thiab ceg tam sim no yuav ntau dua li tag nrho tam sim no.
Los ntawm kev txheeb xyuas ntawm Circuit Court resonance, peb tuaj yeem nkag siab cov yam ntxwv ntawm resonant circuits. Hauv kev tsim tawm tswv yim, peb yuav tsum siv lawv lub zog thiab zam lawv qhov tsis muaj zog.
3, Khoom yam ntxwv ntawmseries resonance thiab parallel resonance
Cov yam ntxwv tseem ceeb ntawm series resonant khoom
1. Lub zog yuav tsum tau txo qis heev
Lub series resonance xeem ntaus ntawv siv ib tug resonant reactor thiab lub capacitance ntawm cov khoom xeem los tsim resonance, yog li tau txais qhov yuav tsum tau high voltage thiab high 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 lub 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 mus rau 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 - Circuit Court 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 yog 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 - cov hluav taws xob hluav taws xob hlawv qhov chaw txhaum.
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.
Cov yam ntxwv tseem ceeb ntawm cov khoom sib txuas resonance
Parallel resonance tuning thiab boosting yog ruaj khov heev, thiab tuning yuav ua tau ntawm tsawg voltages. Cov txheej txheem tuning nyob ntawm qhov loj ntawm qhov tam sim no ntawm qhov siab voltage sab ntawm lub boosting transformer. Thaum qhov tam sim no raug txo qis, nws yog qhov taw tes resonance, thiab tom qab ntawd qhov voltage yog boosted rau qhov yuav tsum tau voltage. Rau qhov tsis siv neeg tuning, nws kuj yog ib qho yooj yim los tswj thiab tuaj yeem zam qhov voltage oscillations thaum lub sij hawm tuning txheej txheem ntawm cov kab.
