Txoj cai thiab tiam ntawm Electromagnetic cuam tshuam EMI
Ua ntej piav txog lub hauv paus ntsiab lus ntawm kev cuam tshuam electromagnetic, peb tam sim no nkag siab txog qhov ua rau EMI:
1. Ua rau EMI
Ntau hom kev cuam tshuam ntawm electromagnetic cuam tshuam yog cov laj thawj tseem ceeb uas cuam tshuam rau kev sib raug zoo ntawm cov khoom siv hluav taws xob.Yog li ntawd, kev nkag siab txog qhov ua rau muaj kev cuam tshuam ntawm electromagnetic cuam tshuam yog qhov tseem ceeb ua ntej rau kev cuam tshuam electromagnetic cuam tshuam thiab txhim kho electromagnetic compatibility ntawm cov khoom siv hluav taws xob.Lub cim ntawm electromagnetic cuam tshuam tuaj yeem muab faib ua:
Internal cuam tshuam Kev cuam tshuam ntawm cov khoom siv hluav taws xob sab hauv
1) Cov khoom siv hluav taws xob ua haujlwm ua rau muaj kev cuam tshuam los ntawm kev xau los ntawm cov khoom siv hluav taws xob faib thiab rwb thaiv tsev ntawm cov kab.
2) Lub teeb liab txuas nrog ib leeg los ntawm impedance ntawm cov xaim hauv av, cov khoom siv hluav taws xob thiab cov xaim xaim, lossis kev cuam tshuam los ntawm kev sib nrig sib inductance ntawm cov xov hlau.
3) Qee cov khoom siv hauv cov khoom siv los yog lub cev ua kom sov, uas cuam tshuam rau kev ruaj ntseg ntawm cov khoom lawv tus kheej thiab lwm yam khoom.
4) Cov khoom sib nqus thiab hluav taws xob tsim los ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob high-voltage cuam tshuam rau kev cuam tshuam los ntawm lwm yam khoom los ntawm kev sib txuas.
Kev cuam tshuam sab nraud - kev cuam tshuam ntawm lwm yam tsis yog cov khoom siv hluav taws xob lossis cov tshuab ntawm circuits, khoom siv lossis tshuab.
1) Sab nraud high voltage thiab fais fab mov cuam tshuam nrog hluav taws xob circuits, khoom siv lossis tshuab los ntawm kev rwb thaiv tsev.
2) Cov khoom siv hluav taws xob sab nraud ua rau muaj zog sib nqus hauv qhov chaw, uas cuam tshuam nrog cov khoom siv hluav taws xob, cov khoom siv lossis cov tshuab los ntawm kev sib koom ua ke inductance.
3) Qhov chaw electromagnetic cuam tshuam rau hluav taws xob circuits lossis tshuab.
4) Qhov kub ntawm qhov chaw ua haujlwm tsis ruaj khov, ua rau muaj kev cuam tshuam los ntawm kev hloov pauv ntawm cov khoom siv hluav taws xob, cov khoom siv lossis cov khoom siv sab hauv.
2. Kev sib kis ntawm electromagnetic cuam tshuam
Thaum qhov zaus ntawm qhov cuam tshuam yog siab, thiab lub wavelength ntawm cov teeb liab cuam tshuam me dua qhov loj ntawm cov khoom cuam tshuam, cov teeb liab cuam tshuam tuaj yeem suav tau tias yog hluav taws xob hluav taws xob, uas radiates electromagnetic zog nyob rau hauv daim ntawv ntawm lub dav hlau electromagnetic waves. thiab nkag mus rau hauv txoj kev ntawm cov khoom cuam tshuam.Nyob rau hauv daim ntawv ntawm coupling thiab coupling, los ntawm cov insulating dielectric, lub coupling ntawm cov impedance feem ntau nkag mus rau hauv interfered system.Cov teeb liab cuam tshuam tuaj yeem nkag mus rau hauv qhov system los ntawm kev coj ncaj qha.
3. Kev ntsuas los txhim kho electromagnetic compatibility
Txhawm rau txhim kho cov khoom siv hluav taws xob sib raug zoo ntawm cov khoom siv hluav taws xob, kev siv hauv av, kev tiv thaiv thiab kev lim dej yog cov txheej txheem yooj yim los tiv thaiv EMI.
1) Hauv av
Grounding yog txoj kev siv hluav taws xob ntawm cov khoom siv hluav taws xob thiab hluav taws xob hauv qhov system mus rau qhov chaw siv hauv av.Ntxiv rau qhov muab kev tiv thaiv kev nyab xeeb hauv av ntawm cov khoom siv, hauv av kuj tseem muab cov teeb liab siv hauv av tsim nyog rau kev ua haujlwm ntawm cov khoom siv.Lub dav hlau hauv av zoo tshaj plaws yog lub cev lub cev nrog xoom lub peev xwm thiab xoom impedance, uas tuaj yeem siv los ua qhov taw qhia rau txhua qhov kev tshuaj xyuas lub teeb liab hauv Circuit Court, thiab ib qho kev cuam tshuam cov teeb liab dhau los ntawm nws yuav tsis tsim qhov hluav taws xob poob.Txawm li cas los xij, tsis muaj lub dav hlau zoo tshaj plaws hauv av, uas xav kom peb xav txog thiab txheeb xyuas qhov kev faib tawm ntawm cov peev txheej hauv av, tsim qauv hauv av thiab kev tshawb fawb, thiab nrhiav kom pom qhov tsim nyog hauv av.Grounding txoj kev tuaj yeem muab faib ua: hauv av ntab, ib qho taw qhia hauv av, ntau lub ntsiab lus hauv av, thiab hybrid grounding.Rau qhov system Circuit Court, muaj kev xaiv: circuit grounding, power grounding, thiab signal grounding.
2) kev tiv thaiv
Shielding yog siv qhov chaw kaw ntawm cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob kom electromagnetically cais cov sab hauv thiab sab nraud.Feem ntau suppress cov hluav taws xob cuam tshuam hauv qhov chaw.Muab faib ua electromagnetic shielding, hluav taws xob tiv thaiv hluav taws xob thiab hluav taws xob tiv thaiv hluav taws xob.
Kev tiv thaiv kev tsim qauv tuaj yeem ua rau ob qho tib si cuam tshuam qhov chaw thiab cov khoom cuam tshuam.Rau qhov cuam tshuam, qhov tsim ntawm qhov thaiv qhov thaiv tuaj yeem txo qhov cuam tshuam rau lwm yam khoom siv nyob ib puag ncig;rau cov khoom cuam tshuam, nws tuaj yeem txo qhov cuam tshuam ntawm sab nraud cuam tshuam electromagnetic tsis ntawm cov khoom siv.
Active shielding: Muab qhov chaw cuam tshuam hauv lub cev tiv thaiv kom tsis txhob muaj hluav taws xob hluav taws xob thiab cuam tshuam cov teeb liab los ntawm kev nkag mus rau hauv qhov chaw sab nraud.
Passive shielding: tso cov khoom rhiab rau hauv lub cev tiv thaiv kom tsis txhob cuam tshuam los ntawm kev cuam tshuam sab nraud.
3) Kev lim dej
Lub ntsiab lus ntawm kev lim dej yog hais txog cov txheej txheem rau kev rho tawm cov cim tseem ceeb los ntawm cov teeb liab qub sib xyaw nrog suab nrov lossis cuam tshuam.EMI limyog cov khoom kom ua tiav kev lim dej.
Qhov tseeb, thaum lub cuab yeej ua haujlwm, nws tseem yuav tsim ntau lub suab nrov.Hloov cov khoom siv hluav taws xob yog qhov cuam tshuam muaj zog heev, thiab EMI teeb liab nws tsim tsis tau tsuas yog siv ntau zaus, tab sis kuj muaj qhov loj me me.Nrog rau kev nthuav tawm ntawm lub teeb liab, cov suab nrov cuam tshuam nrog cov khoom sib txuas tom ntej, thiab qhov sib txuam ntawm cov kev cuam tshuam no tuaj yeem ua rau kev ua haujlwm txawv txav ntawm tag nrho cov Circuit Court.Piv txwv tias lub teeb liab tso zis ntawm lub cuab yeej nrog lub suab nrov thiab pom tseeb cuam tshuam rau cov cuab yeej qis qis yog lim los lim tawm lub suab nrov, qhov cuam tshuam rau cov cuab yeej qis dua yuav raug txo, thiab lub kaw lus yuav ua haujlwm ruaj khov.
