1. Cov txheej txheem hauv kev nthuav dav
Resonant Circuit Coorory
Hauv AC resonance kuaj, koj siv tauresonance mobNyob rau hauv Corrcuit composed ntawm:
A Kuj tsis paub meej inductance(feem ntau yog ib tug high-voltage ntsuas reactor),
TusKuaj Khoom(uas coj tus coj zoo li lub capacitor vim nws cov yam ntxwv rwb thaiv tsev),
Thiab qee zaum atuning capacitorlossis aZaus-kho lub hwj chim.
Nyob rau ntawm resonance:
Qhov twg:
f=zaus (HZ)
L=inductance ntawm kev xeem coil (h)
C=capacitectance ntawm cov khoom xeem (f)
Revonance tso cai rau ib qib zuj zus hauv voltage hla cov khoom xeem nrog txo hwj chim thovLos ntawm lub zog hluav taws xob . Lub voj voos tam sim no nyob rau hauv LC lub voj yog siab, tab sis cov tswv yim tam sim ntawd yog tsawg dua rau cov hwj huam tsawg.
2. Hom AC resonance circuits
Series Resonance Circuit Court (Feem Ntau)
Inductor thiab caperitive thauj khoom (kuaj khoom) hauv series .
Lub zog rau tag nrho cov Circuit Court ncaj qha .
Voltage magnification tshwm sim thoob plaws lub capacitor (kuaj khoom) .
Parallel Revelonance Circuit
Tsawg dua; siv hauv qee qhov kev xeem tshwj xeeb tau teev .
Ntau rhiab rau tuning thiab nyuaj rau tswj .
3. Fais Fab Khoom & Zaus Qhov Chaw
AC resonance cov kev ntsuam xyuas yog feem ntau ua nrog aKuj tsis paub meej-zaus lub zog, feem ntau ntawm30 hz thiab 300 hz, vim tias:
Qis zauspab txo qis peev xwm them tam sim no hauv cov cab loj loj lossis gis .
Tuning zaustso cai rau koj kom ua tiav resonance yam tsis tas yuav muaj cov inductors loj .
Khoom Siv Fais Fabtuaj yeem yog:
Tsav-Generator Seev
Cov hloov pauv hloov pauv (ua rau-lub xeev)
HV transformerspub los ntawm amplifier lossis inverter
4. Dab tsi yog ntsuas?
Cov tsis tseem ceeb:
Kev Ntsuam Xyuas Kev Ntsuas Qib(Feem ntau 1.5-2.0 × ntsuas voltage)
To tam sim no
Tshuaj
Dielectric poob (tan δ)(hauv qee qhov kev teeb tsa siab)
Kev rhuav tshem (yog tias tsis ua hauj lwm tshwm sim)
Qhov kev xeem no feem ntauKev tsav tsheb tiv thaiv, tsis yog kuaj mob . nws qhia meej tias cov rwb thaiv tsev tuaj yeem daws cov haujlwm ua haujlwm rau qhov duration.
Raug kuaj Durations:
15 feebRau cov tshiab txhim kho
30-60 feebRau Kev Ntsuam Xyuas Hoobkas
