Kev soj ntsuam ntawm Electromagnetic Compatibility Tsim rau Hloov Cov Khoom Siv Hluav Taws Xob
Nrog rau txoj kev loj hlob sai ntawm cov cuab yeej siv hluav taws xob, cov khoom siv hluav taws xob kuj tseem txav mus rau kev sib koom ua ke thiab kev ua haujlwm me me, uas ua rau peb muaj ntau yam yooj yim. Txawm li cas los xij, electromagnetic coupling ntawm ntau yam khoom siv hluav taws xob tau dhau los ua qhov teeb meem tseem ceeb ntawm cov engineers. Kev puas tsuaj ntawm hluav taws xob ib puag ncig muaj kuab paug tsis muaj tsawg dua li ntawm ib txwm muaj kuab paug ib puag ncig. Electromagnetic pollution, uas yog ib feem ntawm ib puag ncig muaj kuab paug, kuj tau muab tso rau hauv cov txheej txheem. Thaum lub sijhawm ua haujlwm ib txwm muaj, cov khoom siv hluav taws xob yuav tiv taus ntau yam kev cuam tshuam hluav taws xob, suav nrog kev cuam tshuam ntawm lawv cov khoom siv sab hauv thiab cuam tshuam los ntawm lwm yam khoom siv hluav taws xob nyob ib puag ncig lawv. Tib lub sijhawm, lawv yuav tsim hluav taws xob cuam tshuam rau lwm yam khoom siv hluav taws xob nyob ib puag ncig lawv. Cov kev cai rau cov khoom siv hluav taws xob sib txawv heev hauv ntau qhov chaw thov (tsev neeg, kev tswj hwm kev lag luam, thiab lub zog). Hauv qhov no, kev siv tau tuaj yeem ua rau tus qauv dav dav IEC/EN61000-6 series lossis cov kev xav tau ntawm kev lag luam ntawm cov khoom siv sib xws.
Hom kev cuam tshuam ntawm electromagnetic no feem ntau suav nrog ob txoj hauv kev ntawm kev sib kis: thawj zaug, nws raug xa mus raws li cov hlua hluav taws xob, uas feem ntau suav nrog kev sib kis ntawm lub hwj chim chaw nres nkoj thiab lub teeb liab chaw nres nkoj; Ntawm qhov tod tes, nws tsuas yog kis raws qhov chaw.
Electromagnetic cuam tshuam:
Cov khoom siv hluav taws xob yuav tsum ua kom tau raws li qhov tsawg kawg nkaus emission zog yuav tsum tau nyob rau hauv nws daim ntawv thov ib puag ncig, txwv tsis pub nws yuav ua rau cuam tshuam rau cov khoom siv nyob ib puag ncig. Raws li cov kev xav tau ntawm cov hom dav dav, tus qauv IEC/EN61000-6 tau muab faib ua cov khoom siv ib puag ncig kev lag luam thiab cov kev xav tau emission rau thaj chaw nyob, kev lag luam, thiab lub teeb kev lag luam; Rau cov khoom siv dav dav xws li cov khoom siv hluav taws xob, tshwj tsis yog nws yog tus qauv tshwj xeeb, kev cuam tshuam ntawm electromagnetic cuam tshuam yuav ua raws li IEC / EN61000-6-3 lossis IEC / EN61000-6-4 thaum pib tsim qauv.
Nrog rau qhov txuas ntxiv ntawm cov khoom siv hluav taws xob me me thiab ua kom muaj zog ceev, qhov nyuaj ntawm kev tsim hluav taws xob cuam tshuam hauv lub zog hluav taws xob nws tus kheej tseem nce ntxiv. Tam sim no, MORNSUN tsis tsuas yog muaj cov ntxaij lim dej built-in hauv tag nrho AC-DCs ntawm kev ua lag luam, tab sis kuj tau nqis peev ntau ntawm cov nqi tsim hauv transformer shielding thiab lub zog ntaus ntawv suab nrov, ua tau raws li cov lus cog tseg; Cov khoom siv hluav taws xob qis R2 DC-DC yog txhua yam tsim los nrog rau 6 sab tiv thaiv cov qauv, ua tau raws li cov chav kawm A ntawm EN55022 / CISPR 22 thiab EN55011 / CISPR 11 hauv kev lag luam, thiab ua tau raws li qib yuav tsum tau ua ntawm kev lag luam yooj yim.
Txawm hais tias tus nqi tsim qauv tseem ceeb tau nqis peev rau hauv kev cuam tshuam ntawm electromagnetic cuam tshuam ntawm lub zog hluav taws xob nws tus kheej, uas kuj ua tau raws li cov lus cog tseg, nws tseem yog qhov kev cuam tshuam ntawm electromagnetic cuam tshuam ntawm cov khoom siv hluav taws xob ntau tshaj li tus qauv hauv kev lag luam kev siv; Nyob rau ntawm no, ntau tus tsim engineers ntseeg hais tias lub hauv paus ntawm qhov teeb meem nyob rau hauv lub hwj chim mov, uas yog ib tug misconception. Vim hais tias electromagnetic cuam tshuam ua kev cuam tshuam kev ntsuam xyuas cov haujlwm feem ntau tsom rau qhov chaw nres nkoj fais fab, qhov chaw nres nkoj fais fab dhau los ua nws txoj kev sib kis. Tag nrho cov electromagnetic cuam tshuam yuav dhau los ntawm qhov chaw nres nkoj fais fab mus rau cov khoom siv kuaj, tab sis qhov cuam tshuam ntawm electromagnetic cuam tshuam los ntawm cov khoom siv kuaj tsis yog los ntawm lub zog hluav taws xob xwb, qhov tseem ceeb kuj suav nrog kev cuam tshuam ntawm electromagnetic cuam tshuam los ntawm lwm qhov ntawm lub tshuab tag nrho, thiab. raws li electromagnetic cuam tshuam generated los ntawm resonance ntawm parasitic tsis nyob rau hauv cov khoom. Hom kev cuam tshuam ntawm electromagnetic no yog txuas nrog rau cov khoom siv kuaj los ntawm qhov chaw nres nkoj fais fab, thiab cov lim dej hauv cov khoom siv hluav taws xob tsis tuaj yeem lim qhov no ntawm electromagnetic cuam tshuam. Daim ntawv thov ib puag ncig ntawm cov khoom siv hluav taws xob sib txawv heev, Tag nrho cov khoom siv hluav taws xob tsim cov lim dej yog tsim los daws lawv tus kheej kev cuam tshuam raws li qhov tseem ceeb. Nyob rau tib lub sijhawm, lim attenuation yam ntxwv thiab cov yam ntxwv spectral yuav tsum tau tshwj tseg kom ntau li ntau tau nrog qhov siab tshaj plaws, tab sis nws tsis muaj peev xwm ua tau raws li txhua daim ntawv thov scenarios; Yog li qhov no xav kom peb cov neeg tsim tshuab tag nrho los tsim lub zog pem hauv ntej-kawg raws li daim ntawv thov Circuit Court pom zoo los ntawm cov chaw tsim khoom siv hluav taws xob.
