Qhov zaus AC resonant test system yog siv los txheeb xyuas lub zog rwb thaiv tsev ntawm cov khoom siv hluav taws xob.Nws yog qhov tseem ceeb rau kev txiav txim siab seb cov khoom siv hluav taws xob puas tuaj yeem muab tso rau hauv kev ua haujlwm.Nws kuj yog ib qho tseem ceeb txhais tau tias yuav tsum xyuas kom meej qhov rwb thaiv tsev theem ntawm cov khoom siv thiab tsis txhob cuam tshuam cov rwb thaiv tsev.Vim hais tias cov zaus hloov dua siab tshiab series resonance test device tuaj yeem cuam tshuam txog qhov xwm txheej ntawm cov khoom siv hluav taws xob ua haujlwm hauv AC voltage, nws tuaj yeem pom qhov cuam tshuam ntawm rwb thaiv tsev tsis zoo.
HV HIPOT GDTF series Zaus Hloov Hloov AC Resonant Test System
Vim yog lub hauv paus ntsiab lus ntawm resonance saws los ntawm zaus hloov dua siab tshiab series resonance xeem ntaus ntawv, qhov voltage ntawm ib tug tej zaus nyob rau hauv lub kaw lus voj thiab lub capacitance thiab reactance nyob rau hauv lub voj tsim resonance.Qhov voltage hla lub capacitor mus txog qhov ntsuas voltage.
Raws li cov ntsiab lus saum toj no thiab qhov ntsuas qhov tseeb ntawm qhov chaw, qhov overvoltage ntawm zaus hloov dua siab tshiab resonance feem ntau tshwm sim nyob rau hauv ob qho xwm txheej, ib qho yog thaum lub cuab yeej tshawb nrhiav qhov taw tes resonance thiab cov txheej txheem ntawm kev tsim cov resonance voltage;Lwm qhov yog thaum qhov boost voltage nce mus txog qhov ntsuas voltage.hauv li cas.
Nyob rau hauv cov ntaub ntawv ntawm nrhiav tau lub resonance taw tes nyob rau hauv series resonance thiab boosting nws mus rau lub xeem voltage, feem ntau nyob rau hauv cov ntaub ntawv uas lub withstand voltage ntawm cov khoom xeem yog tsis tsim nyog los yog lub site ib puag ncig tsis tau hloov loj, qhov kev xeem yuav tsis tsim overvoltage tiv thaiv. los yog lwm yam txhaum.Txawm li cas los xij, txij li qhov hluav taws xob hluav taws xob tsis tas li thiab qhov hluav taws xob tawm ntawm cov khoom siv hluav taws xob hloov pauv, cov zis hluav taws xob siab kuj muaj qee yam tsis hloov pauv, uas yuav ua rau muaj kev tiv thaiv overvoltage ntawm lub zog siab kawg.Yog hais tias lub hwj chim mov voltage hloov pauv, koj tuaj yeem kho qhov kev tiv thaiv overvoltage ntawm qhov ntsuas, thiab teeb tsa kev tiv thaiv overvoltage rau tus nqi siab.Peb feem ntau xav tau qhov kev tiv thaiv overvoltage rau 1.1-1.2 npaug ntawm kev tiv thaiv hluav taws xob.Lub sijhawm no, nws yog qhov yooj yim tsis muaj teeb meem los teeb tsa rau 1.2 zaug.
Cov saum toj no yog ib qho teeb meem yooj yim, tab sis nws yog qhov nyuaj rau kev hloov pauv ntawm qhov hluav taws xob ua rau overvoltage tshwm sim thaum kev tiv thaiv overvoltage raug teeb tsa.Feem ntau, lub overvoltage ntawm zaus hloov dua siab tshiab series resonance xeem ntaus ntawv yog nyob rau hauv lub zaus cheb theem ntawm lub ntsuas, uas yog, nyob rau hauv tus txheej txheem ntawm nrhiav lub resonance point.Tus neeg twg uas tau siv qhov zaus hloov dua siab tshiab series resonance test ntaus ntawv paub tias nyob rau hauv tus txheej txheem ntawm kev nrhiav cov resonance point ntawm zaus hloov dua siab tshiab series resonance test ntaus ntawv, qhov voltage thiab zaus muaj tib txoj kab sib txuas raws li ib tug parabola.Los ntawm lub neej ntawd, lub kaw lus pom qhov hluav taws xob ntau dua, uas yog, lub vertex ntawm parabola, raws li qhov taw tes resonance.Txij li thaum txoj kev xav ntawm lub hauv paus ntsiab lus resonance tuaj yeem cuam tshuam qhov voltage qis rau 80 zaug (vim qhov zoo tshaj plaws thiab lwm yam kev sib raug zoo feem ntau tsis tshaj 30 zaug), qhov voltage yuav tsum tau siv rau zaus cheb ntawm zaus hloov dua siab tshiab series resonance test ntaus ntawv feem ntau 20. -50V, thiab qhov voltage tom qab excitation feem ntau yog rau ob peb puas volts.Los ntawm cov ntsiab lus saum toj no, peb pom tias yog tias qhov ntsuas hluav taws xob ntawm cov khoom ntsuas peb xav tau qis dua qhov hluav taws xob thaum lub kaw lus resonance yog qhov taw tes resonance, lub kaw lus yuav muaj kev tiv thaiv overvoltage thaum nws cia li tshawb nrhiav qhov resonance point.Lub sijhawm no, tag nrho qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob resonance tsis tuaj yeem tiv taus qhov siab, qhov ntsuas tsis tuaj yeem ua tiav.
Txoj kev daws teeb meem no kuj muaj teeb meem.Nws tsis yog hais tias qhov sib txawv zaus series resonance xeem ntaus ntawv tsis tuaj yeem tsim qhov ntsuas hluav taws xob, tab sis qhov hluav taws xob resonance siab dua qhov ntsuas hluav taws xob.Peb paub hais tias lub default resonance voltage ntawm lub system yog lub vertex ntawm lub parabola, uas yog hais tias, thaum lub parabola nce mus rau hauv tus txheej txheem ntawm vertex los yog vertex nqis, yuav muaj ib tug taw tes uas yog raws li qhov ntsuas voltage point.Peb tsuas yog yuav tsum tau kuaj phau ntawv ntsuas ntawm zaus hloov pauv zaus resonance, thiab siv phau ntawv zaus tshawb nrhiav kom pom qhov zaus zaus raws li qhov siv hluav taws xob siv thiab tom qab ntawd tiv taus qhov voltage los daws qhov teeb meem overvoltage hauv cov txheej txheem ntawm kev nrhiav qhov taw tes resonance.
