Cov kev rov qab ua haujlwmNyob rau hauv UHV lub hwj chim tuaj yeem pab cov neeg ua haujlwm hauv lub zog ntau ntau cov hwj huam kev sim ntau cov kev sim yooj yim dua.
1, Txheej txheem cej luam ntawm cov yam ntxwv ntawm cov txheej txheem resonance thiab parallel resonance
Tus Qauv Sib Txawv Ntau Dua Resonance Test Ntaus, tseem paub tias yog kev rov qab kho dua tshiab, yog tsim ntawm cov hluav taws xob sib txawv hluav taws xob muab cov khoom siv hluav taws xob, kev ua kom zoo nkauj, ua hluav taws xob, thiab muaj peev xwm voltitection divider. Tus Capacitor And Reactor ntawm cov qauv kuaj ntsuas ua ib qho kev sib txuas-kev sib txuas tau; Qhov ntsuas hluav taws xob txuas nrog rau kev ntsuas mus ntsuas qhov kev ntsuas tus resonant rau cov qauv ntsuas thiab muab cov teeb meem tiv thaiv teeb meem; Lub zaus ua cov zog hluav taws xob tau txuas nrog cov kab kev uas muaj zog ntawm kev hloov pauv, muab lub zog kom zoo rau kev rov ua haujlwm.
Nyob rau hauv lub voj voog uas inductors thiab capacitors tau txuas nrog rau theem, thaum muaj lub zog hluav taws xob tau txais los ntawm cov resistor thiab dhau los ua tus tiv taus Circuital Circuit Court, nws yog hu ua kev hloov pauv thaum sib tw. Cov kev rov pib ua tiav yog kev them nyiaj ua tiav, uas lub zog hluav taws xob tsis tas yuav muab lub zog reactive, tsuas yog lub zog uas xav tau los ntawm lub resistor.
Thaum lub sijhawm resonance, tag nrho cov kev tam sim no ntawm lub voj voog yog qhov tsawg, thaum cov ceg tam sim no feem ntau ntau dua li qhov tam sim no ntawm Circuit Court. Yog li ntawd, kev sib tw thaum sib tw yog tseem hu ua kev rov ua haujlwm tam sim no. Thaum sib tw sib tw tshwm sim, ib qho loj tam sim no ntws los ntawm kev siv hluav taws xob thiab kev sib xyaw ua ke, uas tuaj yeem ua rau muaj kev huam yuaj xws li cov khoom siv hluav taws xob; Tab sis hauv xov tooj cua engineering, feem ntau yog siv los xaiv cov cim thiab tshem tawm kev cuam tshuam.
2, Circuit Court cov yam ntxwv ntawm cov kev rov qab kho dua tshiab thiab cov kev rov qab ua ke
Cov yam ntxwv ntawm cov kab ke ntawm cov kev rov qab kho dua tshiab
1. Tus nqi tsawg kawg nkaus tag nrho cov nqi: z=r + j (wc) {{4} r;
Thaum lub zog hluav taws xob voltage yog tas mus li, tam sim no yog nyob ntawm qhov siab tshaj plaws; Kuv {= Kuv 0= u /|z |=u / r;
3. Lub Circuit Court yog Resistive, thiab qhov hluav taws xob ntawm lub capacitor lossis inductor yuav siab dua lub zog hluav taws xob.
Cov yam ntxwv ntawm parallel resonance Circuit Court
Thaum qhov hluav taws xob yog tas li, tam sim no yog qhov txo qis thaum lub sijhawm rov qab;
2. Qhov siab tshaj plaws kev xav;
3. Lub Circuit Court yog Resistive, thiab cov ceg tam sim no yuav loj dua tag nrho cov tam sim no.
Los ntawm kev tsom xam ntawm Circuit Court resonance, peb tuaj yeem nkag siab cov yam ntxwv ntawm resonant circuits. Hauv kev ua haujlwm pheej yig, peb yuav tsum siv lawv cov peev xwm thiab zam lawv cov kev qaug zog.
3, Cov khoom lag luam ntawm cov txheej txheem resonance thiab parallel resonance
Cov yam ntxwv tseem ceeb ntawm Series cov khoom lag luam
1. Qhov uas xav tau lub hwj chim muaj peev xwm tau txo qis heev
Cov txheej txheem ntsuas ntsuas ntsuas siv cov reactor thiab lub peev xwm ntawm cov khoom ntsuas los tsim cov khoom lag luam uas yuav tsum muaj dua thiab siab tam sim no. Hauv tag nrho cov kab ke, cov hluav taws xob tsuas yog xav tau ib feem ntawm cov kab ke. Yog li, qhov xav tau hluav taws xob uas yuav tsum tau rau qhov kev xeem tsuas yog 1 / q Times Qhov Kev Ntsuas Muaj Peev Xwm (q yog qhov zoo).
2. Qhov hnyav thiab ntim ntawm cov khoom siv tau raug txo qis
Nyob rau hauv cov txheej txheem resonant, tsis yog tsuas yog lub zog hluav taws xob ntau ntxiv Thiab ntim, feem ntau 1/5 txog 1/10 ntawm cov khoom siv xeem sib txawv.
3. Txhim kho cov zis hluav taws xob waveForm
Ib lub zog uas resonant yog ib lub zog lim dej uas muaj peev xwm txhim kho cov nthwv hluav taws xob, kom muaj kev tawm suab zoo, thiab tiv thaiv cov kev ntsuas cuav ntawm cov qauv sib txawv.
4. Tiv thaiv cov tsiaj loj luv luv ntawm kev hlawv cov plaub hau
Nyob rau hauv lub xeev resonant, thaum lub sij hawm muaj zog ntawm lub rwb thaiv tsev ntawm cov kev ntsuas uas tau tawg, tsis tau ntsib cov kev hloov kho kom sai sai rau 1 / q ntawm qhov kev sim ib txwm tam sim no. Thaum coj AC wallage cov kev ntsuam xyuas siv cov kev hloov pauv paralel lossis cov kev ntsuas ib txwm muaj los yog cov khoom siv ua ib txwm muaj tam sim no nce los ntawm ob peb kaum ntawm lub sijhawm. Piv rau ob, luv-Circuit Court tam sim no thiab tawg tam sim no txawv ntawm ntau pua lub sijhawm. Yog li, suam kev resonance tuaj yeem txheeb xyuas cov rwb thaiv tsev tsis muaj zog yam tsis muaj kev txhawj xeeb ntawm cov khoom tawg luv tawg ntawm qhov txhaum.
5. Yuav tsis muaj kev txhawb nqa rov qab
Thaum kev kuaj ntsuas qhov ua piv txwv kev rhuav tshem thiab ploj ntawm resonance tej yam kev mob, lub arc yog tam sim ntawd tua, thiab cov zis tau txiav tawm.
Cov yam ntxwv tseem ceeb ntawm kev hloov kho cov khoom lag luam parallel
Parallel Resononance tuning thiab boosting yog heev ruaj khov, thiab nyob li cas tuaj yeem ua tau ntawm tsawg voltages. Txoj kev ua siab nyob ntawm qhov tseem ceeb ntawm qhov tam sim no ntawm cov hluav taws xob siab ntawm txoj kev txhawb nqa. Thaum cov tam sim no yog qhov tsawg, nws yog lub ntsiab lus resonance, thiab tom qab ntawd lub voltage yog boosted rau cov voltage uas yuav tsum tau. Rau kev siv lub ding, nws tseem yooj yim los tswj thiab tuaj yeem zam kev tiv thaiv cov oscillations thaum lub qhov ntsuas ntawm cov txheej txheem ntawm cov txheej txheem.
