Electromagnetic Compatibility Standards ntawm Switching Fais fab mov ntawm tsev thiab txawv teb chaws

Electromagnetic compatibility qauv ntawm kev hloov fais fab mov hauv tsev thiab txawv teb chaws

Electromagnetic compatibility yog hais txog lub peev xwm ntawm lub cuab yeej lossis lub cev ua haujlwm ib txwm nyob hauv nws qhov chaw electromagnetic tsis ua rau muaj kev cuam tshuam tsis zoo ntawm electromagnetic cuam tshuam rau txhua yam hauv ib puag ncig.

Nws yog tsis yooj yim sua kom tshem tawm tag nrho cov electromagnetic cuam tshuam ntawm cov cuab yeej thiab yuav insensitive rau tag nrho cov sab nraud electromagnetic cuam teeb liab. Tsuas yog los ntawm kev tsim cov qauv ntawm qhov tso cai electromagnetic cuam tshuam thiab muaj peev xwm tiv thaiv electromagnetic cuam tshuam ntawm cov cuab yeej tuaj yeem ua tau raws li qhov xav tau ntawm electromagnetic compatibility ntawm cov khoom siv hluav taws xob thiab cov tshuab. Ib tug loj tus naj npawb ntawm electromagnetic compatibility qauv nyob rau hauv tsev thiab txawv teb chaws teeb meem rau cov khoom siv nyob rau hauv lub kaw lus kom ua tiav electromagnetic compatibility nrog ib leeg.

Pawg Neeg Tshwj Xeeb ntawm Kev Tshawb Fawb Txog Xov Xwm Thoob Ntiaj Teb (cispr) yog lub koom haum electromagnetic compatibility standardization nyob rau hauv International Electrotechnical Commission (iec). Thaum ntxov li 1934, nws pib kawm tus qauv emc, nrog rau tshooj. Ntawm lawv, Sixth Sub-committee (scc) yog lub luag haujlwm tseem ceeb rau kev tsim cov qauv rau kev cuam tshuam kev ntsuas kev txais thiab cov qauv ntsuas. Cispr16 "cov lus qhia tshwj xeeb rau kev cuam tshuam hauv xov tooj cua thiab ntsuas kev tiv thaiv kab mob" muab cov ncauj lus kom ntxaws txog kev ua haujlwm ntawm EMC ntsuas txais, cov cuab yeej pabcuam thiab cov txheej txheem calibration. Cispr17 "Kev Ntsuas Kev Tiv Thaiv Cov Yam Ntxim Saib Ntxim Ua ntawm Xov Tooj Cua cuam tshuam cov lim dej thiab cov khoom tiv thaiv" tau tsim cov qauv ntsuas ntawm cov ntxaij lim dej. Cispr22 "Limits and Measurement Methods of Radio Interference of Information Technology Equipment" stipulates cov kev txwv ntawm electromagnetic cuam tshuam tsim los ntawm cov khoom siv technology hauv cov zaus ntau ntawm 0.15 ~ 1000 MHz. Cispr24 "Txheej Txheem thiab Kev Ntsuas Kev Tiv Thaiv Kev Tiv Thaiv Cov Khoom Siv Technology" qhia txog kev tiv thaiv kev ua tau zoo ntawm cov khoom siv thev naus laus zis rau kev cuam tshuam sab nraud hauv lub sijhawm sau npe thiab zaus sau npe. Ntawm lawv, cispr16, cispr22 thiab cispr24 tsim EMC cov ntsiab lus xeem thiab cov qauv kev xeem ntawm cov khoom siv thev naus laus zis, suav nrog cov khoom siv sib txuas lus hloov hluav taws xob, uas yog qhov tseem ceeb tshaj plaws rau EMC tsim kev sib txuas lus hloov hluav taws xob tam sim no.

Tsis ntev los no Iec tau tshaj tawm ntau tus qauv ntawm cov qauv electromagnetic compatibility, tus neeg sawv cev feem ntau yog iec61000 series qauv. Nws qhia txog cov kev xav tau ntawm electromagnetic compatibility rau xob laim, surge, electrostatic paug (esd), hluav taws xob ceev ceev (eft), tam sim no harmonics, voltage sag, voltage transient thiab luv luv cuam tshuam, voltage fluctuation thiab flicker, radiated electromagnetic teb, kev tiv thaiv rau Kev cuam tshuam los ntawm RF electromagnetic teb, ua cuam tshuam thiab cuam tshuam hluav taws xob.

Tsis tas li ntawd, fcc15 tsim los ntawm Tsoom Fwv Teb Chaws Council ntawm Tebchaws Meskas, vde08712a1, vde08712a2 thiab vde0878 tsim los ntawm German Lub Tsev Haujlwm Hluav Taws Xob Hluav Taws Xob txhua tus xav tau cov khoom siv sib txuas lus electromagnetic.

Tuam Tshoj txoj kev tshawb fawb ntawm electromagnetic compatibility qauv yog kuj lig. Cov txheej txheem tseem ceeb tau txais yuav yog kev taw qhia, kev zom zaub mov thiab kev nqus, thiab cov khoom txawv teb chaws ua haujlwm rau Tuam Tshoj yog txoj hauv kev tseem ceeb rau kev tsim cov qauv hauv tsev electromagnetic compatibility. Xyoo 1998, raws li cispr22, iec61000 series qauv thiab ituto.41 cov qauv, Ministry of Information Industry formulated yd/t9831998 "Limits and Measurement Methods of Electromagnetic Compatibility of Communication Power Supply Equipment", uas tau teev nyob rau hauv kom meej qhov tshwj xeeb. kuaj cov khoom, cov kev xav tau thiab kev sim ntawm electromagnetic compatibility ntawm kev sib txuas lus cov khoom siv hluav taws xob, suav nrog kev sib txuas lus hloov hluav taws xob, thiab txhais cov hom phiaj tsim rau kev tshuaj xyuas electromagnetic compatibility, ncav cuag tus qauv thiab dhau lub network soj ntsuam.
