Series 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 resonance, kuj hu uasib txawv zaus series resonance test device, 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 cov hluav taws xob hluav taws xob hluav taws xob. 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 txuas mus rau series resonant Circuit Court los ntawm lub excitation transformer, muab lub zog excitation rauseries resonance.
Lub ntsiab lus ntawm series resonance
Nyob rau hauv AC Circuit Court nrog resistor R, inductor L, thiab capacitor C, series resonance feem ntau tshwm sim nyob rau hauv ntau theem ntawm voltage thiab tam sim no ntawm ob kawg ntawm lub Circuit Court. 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 zoo ib 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 lub xeev resonant, tag nrho impedance ntawm Circuit Court ncav cuag los yog kwv yees nws cov nqi siab tshaj plaws. Lub hom phiaj ntawm kev kawm resonance yog kom nkag siab txog lub hom phiaj tshwm sim no thiab siv nws cov yam ntxwv hauv kev tshawb fawb thiab kev siv thev naus laus zis, thaum tseem tiv thaiv kev puas tsuaj nws yuav ua rau. Muaj ob hom kev sib txuas hauv Circuit Court: series resonance thiab parallel resonance. Nyob rau hauv ib tug series Circuit Court muaj li ntawm resistors, inductors, thiab capacitors, thaum lub capacitive reactance XC yog sib npaug zos rau inductive reactance XL, piv txwv li XC=XL, lub theem ntawm voltage U thiab tam sim no I nyob rau hauv lub Circuit Court yog tib yam, thiab lub Circuit Court exhibits ntshiab kuj. Qhov tshwm sim no yog hu ua series resonance (tseem hu ua voltage resonance). Thaum ib tug series resonance tshwm sim nyob rau hauv lub Circuit Court, impedance ntawm lub Circuit Court Z=√ R2+XC-XL2=R, tag nrho impedance nyob rau hauv lub Circuit Court yog txo, thiab tam sim no yuav ncav cuag nws qhov siab tshaj plaws tus nqi.
Txoj cai ntawm series resonance
Nyob rau hauv Circuit Court zaus, resonance tshwm sim nyob rau hauv lub Circuit Court, thiab qhov voltage ntawm lub xeem qauv yog Q lub sij hawm cov zis voltage ntawm lub excitation transformer high voltage kawg. Q yog qhov system zoo tshaj plaws, uas yog qhov voltage resonance ntau, feem ntau ntawm kaum mus rau pua lossis ntau dua. Ua ntej, kho qhov tso zis ntau zaus ntawm qhov sib txawv ntawm lub zog hluav taws xob los ua kom muaj cov resonance hauv Circuit Court, thiab tom qab ntawd kho cov zis voltage ntawm qhov sib txawv ntawm lub zog hluav taws xob nyob rau hauv cov xwm txheej ntawm Circuit Court resonance kom ua tiav qhov ntsuas tus nqi ntawm cov qauv voltage. Vim lub resonance ntawm lub Circuit Court, ib tug me me tso zis voltage ntawm lub variable zaus fais fab mov tuaj yeem tsim kom muaj qhov ntsuas hluav taws xob ntau dua ntawm cov qauv ntsuas CX.
Qhov zoo ntawm series resonance
1. Lub zog yuav tsum tau txo qis heev. XB-f series series series resonance test device siv lub resonant reactor thiab kuaj capacitor los tsim resonance, yog li tau txais qhov yuav tsum tau muaj 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.
