EMC, EMI thiab EMS ntawm coj raj
Kev lig kev cai, EMC suav nrog ob yam: EMI (cuam tshuam kev cuam tshuam hluav taws xob) thiab EMS (hluav taws xob tiv taus hluav taws xob).
Kev siv hluav taws xob sib nqus (EMC) hais txog lub peev xwm ntawm lub cuab yeej lossis cov txheej txheem los ua haujlwm raws li qhov yuav tsum tau ua hauv nws ib puag ncig hluav taws xob thiab tsis tsim hluav taws xob cuam tshuam tsis tau rau ib qho khoom siv hauv nws ib puag ncig.
Yog li ntawd, EMC suav nrog ob qhov yuav tsum tau ua: ntawm ib sab, kev cuam tshuam hluav taws xob tsim los ntawm cov cuab yeej mus rau ib puag ncig thaum lub sijhawm ua haujlwm ib txwm tsis tuaj yeem tshaj qhov txwv; ntawm qhov tod tes, nws txhais tau hais tias cov cuab yeej siv muaj qee qib kev cuam tshuam hluav taws xob hauv ib puag ncig. Qib ntawm kev tiv thaiv kab mob, uas yog, kev tiv thaiv hluav taws xob. Qhov kev cuam tshuam hluav taws xob sib nqus hais txog txhua yam tshwm sim hluav taws xob uas tuaj yeem ua rau kev ua haujlwm ntawm lub cuab yeej lossis lub system puas tsuaj. Qhov kev cuam tshuam hluav taws xob sib nqus hais txog kev ua haujlwm tsis zoo ntawm cov cuab yeej lossis cov txheej txheem los ntawm kev cuam tshuam hluav taws xob.
EMC tau txhais raws li< lub="" peev="" xwm="" ntawm="" lub="" cuab="" yeej="" lossis="" cov="" txheej="" txheem="" ua="" haujlwm="" ib="" txwm="" nyob="" hauv="" nws="" ib="" puag="" ncig="" hluav="" taws="" xob="" thiab="" tsis="" tuaj="" yeem="" tiv="" taus="" hluav="" taws="" xob="" cuam="" tshuam="" rau="" txhua="" yam="" hauv="" ib="" puag="" ncig=""> EMI (Electro Magnetic cuam tshuam) Electromagnetic cuam tshuam EMC (Electromagnetic Compatibility) Sib xws EMC=EMI + EMS EMI suav nrog kev coj ua, hluav taws xob, kev sib haum xeeb thiab lwm yam.
Harmonics thiab flicker yuav tsum yog EMI, tsis yog EMS, saib cov lus qhia ntawm 61000-3 tsev neeg tus qauv: ntu no ntawm IEC 1000-3 yog kev txhawj xeeb nrog kev txwv ntawm qhov hloov pauv ntawm qhov hluav taws xob thiab flicker txaus siab rau cov pej xeem cov hluav taws xob qis. Nco tseg" Impress on" yog siv tsis yog siv, yog li sib haum xeeb thiab flicker yog sab nraud rau cov cuab yeej siv, tsis yog sab nraud rau cov cuab yeej siv, yog li nws yog EMI, tsis yog EMS.
