AC tiv taus qhov ntsuas hluav taws xob yog qhov nruj tshaj plaws, ua haujlwm tau zoo, thiab ncaj qha kev sim ntsuas kev ntsuas lub zog rwb thaiv tsev ntawm cov khoom siv hluav taws xob, thiab nws kuj yog ib qho kev sim uas yuav tsum tau ua raws li cov cai tam sim no. Tam sim no nws yog ib qho kev txiav txim siab rau kev txiav txim siab seb cov khoom siv hluav taws xob puas tuaj yeem muab tso rau hauv Suav teb, thiab nws kuj yog ib qho tseem ceeb rau kev tshawb nrhiav kom ntseeg tau tias cov khoom siv hluav taws xob tsis zoo thiab tsis txhob cuam tshuam kev cuam tshuam ntawm kev puas tsuaj. Nrog rau kev txhim kho txuas ntxiv ntawm Tuam Tshoj lub zog hluav taws xob, ntau dua thiab siab dua -voltage thiab cov khoom siv hluav taws xob loj thiab hla- txuas polyethylene cables tau siv dav. Hauv kev saib xyuas txhua hnub thiab kev kuaj xyuas ua haujlwm, AC voltage tiv thaiv kev ntsuas yog ib qho tseem ceeb ntawm cov khoom kuaj. Vim qhov loj thiab tsis yooj yim kev thauj mus los ntawm cov tsoos fais fab zaus sim transformers, thiab xav tau ib tug loj muaj peev xwm kuaj fais fab mov thaum ua AC voltage tiv thaiv kev ntsuam xyuas ntawm loj muaj peev xwm hluav taws xob cov cuab yeej, tej zaum nws yog tsis yooj yim sua rau kev ntsuam xyuas ntawm qhov chaw. Yog li ntawd, ib qho tshiab AC voltage withstand test device yog xav tau rau kev sim. Nrog rau kev txhim kho lub zog thev naus laus zis, kev sim tshiab tau maj mam tau txais. Ntawm lawv, series resonant voltage withstand test yog ib qho ntawm lawv uas haum rau Tuam Tshoj lub teb chaws tej yam kev mob. Nws siv lub hauv paus ntsiab lus ntawm resonant circuits thiab tuaj yeem muab faib ua peb hom raws li kev hloov pauv sib txawv: inductive, capacitive, thiab qhov sib txawv. Los ntawm kev sib piv ntawm peb hom series resonant pab kiag li lawm nyob rau hauv cov ntaub ntawv siv, nws pom tau hais tias qhov sib txawv zaus series resonant ntaus ntawv yog ntau haum rau cov kev xav tau ntawm qhov chaw. Yog li ntawd, nyob rau hauv lub teb cov cuab yeej AC xeem, feem ntau siv yog covsib txawv zaus series resonant ntaus ntawv, uas tuaj yeem ua tau raws li ntau yam AC voltage tiv thaiv kev sim.
Los ntawm kev xa mus rau ntau yam duab thiab cov ntaub ntawv, peb tuaj yeem nkag siab qhov feem ntau siv rau ntawm - txoj kev hloov kho qhov chaw rau series resonance tiv taus qhov ntsuas hluav taws xob, suav nrog cov txheej txheem inductive thiab sib txawv. Txawm li cas los xij, txawm li cas los xij, nws cia siab tias qhov siab -voltage Circuit Court tuaj yeem hloov kho rau qhov inductive impedance sib npaug ntawm lub peev xwm, uas yog, o L=1/C. Txoj kev no, tsuas yog qhov hluav taws xob me me yuav tsum tau siv rau qhov nruab nrab hloov pauv, thiab qhov hluav taws xob siab QU (Q=L/R=1}/o CR, qhov zoo tshaj plaws) yuav raug tsim tawm ntawm cov qauv kuaj
Txawm hais tias muaj hluav taws xob txaus txaus tuaj yeem tsim tawm ntawm cov qauv ntsuas yog nyob ntawm peb yam hauv qab no:
① Puas yog tag nrho inductance ntawm high -voltage circuit sib npaug rau tag nrho cov peev xwm;
② Puas yog tus nqi zoo tshaj ntawm qhov siab -voltage circuit loj txaus;
③ Puas yog qhov voltage U siv rau qhov nruab nrab transformer loj txaus.
Qhov tseem ceeb tshaj plaws ntawm cov cuab yeej inductive yog cov tub ntxhais hlau reactor nrog adjustable inductance, uas kho cov hlau tub ntxhais huab cua sib txawv ntawm lub reactor hloov nws inductance. Qhov kom zoo dua ntawm cov cuab yeej no yog qhov inductance ntawm lub reactor tuaj yeem ua tau loj heev, uas tuaj yeem siv los tiv thaiv qhov ntsuas hluav taws xob ntawm cov qauv loj capacitance. Qhov loj ntawm qhov inductance tuaj yeem hloov kho raws li linearly, thiab series Circuit Court tuaj yeem ua kom ncav cuag qhov taw tes resonance raws nraim raws li lub peev xwm ntawm cov qauv. Los ntawm thawj zaug siv qhov hluav taws xob tsawg los kho qhov inductance ntawm lub reactor los tsim resonance nyob rau hauv lub series Circuit Court, thiab tom qab ntawd nce qhov voltage, lub inductance ntawm lub reactor yuav raug kho kom txog rau thaum resonance tshwm sim nyob rau hauv lub xeem voltage. Qhov no yog ob qho tib si nyab xeeb thiab tuaj yeem ua tiav resonance ntawm Circuit Court. Qhov tsis zoo yog tias kev tsim khoom ntawm lub reactor yog complex, thiab qhov hnyav ntawm cov cuab yeej nce.
Cov khoom siv zaus hloov pauv tau nyob ntawm qhov siab - lub zog hloov pauv hloov pauv lub zog hloov pauv hloov lub zog zaus, kom lub voj voog mus txog qhov chaw resonance. Lub inductance ntawm lub reactor siv nyob rau hauv lub ntaus ntawv yog tsau, thiab zaus ntawm lub xeem lub hwj chim mov txawv nrog lub capacitance. Qhov sib txawv zaus series resonance xeem ntaus ntawv siv lub hauv paus ntsiab lus ntawm series resonance, siv ib tug excitation transformer kom excite lub series resonance Circuit Court, kho cov zis zaus ntawm qhov sib txawv zaus xws li, thiab ua rau lub Circuit Court inductance L thiab cov qauv kuaj C.
Series resonance, qhov twg qhov resonant voltage yog qhov voltage siv rau cov qauv kuaj, muaj qhov zoo ntawm kev ncav cuag qhov resonance point raws nraim, ua rau lub reactor yooj yim, lub teeb yuag, thiab muaj qhov zoo tshaj plaws ntawm lub voj voog. Txawm li cas los xij, qhov tsis zoo yog tias nws yuav tsum muaj lub siab - lub zog hluav taws xob, uas muaj cov kev xav tau siab rau kev ruaj ntseg ntawm lub zog hluav taws xob qhov hluav taws xob thiab zaus. Kev hloov kho ntau yam ntawm cov zaus hloov pauv yog loj dua li ntawm hom inductive. Nrog rau kev nce qib ntawm cov khoom siv hluav taws xob, kev hloov pauv zaus feem ntau yog siv tam sim no.
Teeb meem nrog series resonance tiv taus qhov ntsuas hluav taws xob hauv qhov tseeb ntawm - qhov xwm txheej ntawm qhov chaw
Hauv kev siv tiag tiag ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv resonant ntawm qhov chaw, peb feem ntau ntsib cov teeb meem xws li qhov tsis zoo, tsis tshua muaj resonant zaus, thiab siab tam sim no nyob rau hauv qhov ntsuas hluav taws xob, uas yuav tsum tau sau tseg los ntawm cov neeg ua haujlwm kuaj. Cov kev ntsuas sib xws yuav tsum raug coj los daws cov teeb meem no kom ntseeg tau tias kev ua tiav ntawm AC tiv taus qhov ntsuas hluav taws xob.
