Cov xwm txheej tam sim no ntawm electromagnetic compatibility txhim kho kev sib txuas lus hauv tsev hloov hluav taws xob
Txij li thaum kev tsim qauv ntawm yd / t983 tus qauv, kev sib txuas lus hauv tsev fais fab kev lag luam tau pib tshawb fawb ntawm electromagnetic compatibility. Vim yog tus nqi siab ntawm cov khoom siv electromagnetic compatibility test, kuaj qhov chaw, thiab xav tau kev paub txog R & D cov neeg ua haujlwm, ntau lub tuam txhab tsis muaj lawv tus kheej qhov chaw kuaj, electromagnetic compatibility ntawm kev tshawb fawb tau ua rau qee qhov teeb meem. yd/t983 tus qauv, cov kev tiv thaiv kev ntsuas ntsuas tau xaiv los ntawm cov qauv txawv teb chaws hauv qib qis. Ntxiv rau qhov ntsuas hluav taws xob hluav taws xob, esd thiab eft, lwm cov ntsuas kev tiv thaiv kab mob kuj yooj yim kom ua tau raws li qhov yuav tsum tau ua. Cov ntsuas hluav taws xob cuam tshuam, xws li cov ntsuas ntsuas hluav taws xob cuam tshuam, yog qhov nyuaj ua kom tau raws li cov qauv kev xav tau, uas yog qhov hotspot ntawm kev tshawb fawb electromagnetic compatibility tam sim no, thiab tsuas yog ob peb lub tuam txhab hauv tsev tuaj yeem ua tau raws li cov cai ntawm cov qauv tsim nyog.
ZTE Corporation tau tsim nws tus kheej electromagnetic compatibility laboratory, thiab tau cog lus rau kev tshawb fawb electromagnetic compatibility nyob rau theem pib ntawm kev sib txuas lus hloov hluav taws xob kev tshawb fawb thiab kev loj hlob. Cov theem pem hauv ntej ntawm kev sib txuas lus hloov hluav taws xob txais kev siv hluav taws xob zoo tshaj plaws kho tshuab thiab tsis muaj kev nqus hluav taws xob, thiab cov theem tom qab DC / DC txais yuav xoom-voltage-zero-tam sim no (zvzcs) theem-shifted resonance soft-switching thev naus laus zis lossis ob lub raj zoo excitation lossless absorption soft-hloov tshuab, thiab los ntawm cov kws tshaj lij fais fab mov input / tso zis lim tsim thiab xob laim-pov thawj tsim, nrog rau kev nyab xeeb ntawm tag nrho lub tshuab, kev tiv thaiv zoo li qub ntawm digital interface circuit, thiab tsim los tiv thaiv cov pab pawg neeg pulse ceev, tag nrho lub tshuab muaj kev tiv thaiv los ntawm EMC cov cai ntawm cov qauv tsim nyog. Los ntawm kev tshaj lij fais fab kev lag luam tawm tswv yim thiab tso zis lim tsim thiab kev tiv thaiv hluav taws xob tsim, nrog rau kev nyab xeeb ntawm tag nrho lub tshuab, tiv thaiv zoo li qub tsim ntawm digital interface Circuit Court thiab tiv thaiv kev cuam tshuam ceev ceev pab pawg tsim, thiab electromagnetic shielding tsim ntawm tag nrho. tshuab qauv, tsis tsuas yog ua rau lub internal electromagnetic ib puag ncig ntawm tag nrho cov tshuab yog zoo, ruaj khov, thiab txhim khu kev ntseeg, tab sis kuj ua rau kev sib txuas lus hloov fais fab mov mus rau sab nraud ntawm lub tam sim no harmonics, hluav taws xob undulation thiab flickering, conductive cuam tshuam thiab radiated cuam tshuam. kom ua tau raws li qhov xav tau ntawm cispr22 tus qauv ntawm chav kawm A. Cov tswv yim AC fais fab kab muaj peev xwm tiv taus yam tsawg ± 6kv (1.2/50μs thiab 8/20μs ua ke yoj) surge voltage cuam tshuam, thiab DC fais fab kab muaj peev xwm tiv taus yam tsawg kawg nkaus ± 2kv surge voltage; tag nrho cov tshuab sab nraud tuaj yeem tiv taus yam tsawg kawg nkaus ± 8kv electrostatic paug (esd) cuam tshuam, yam tsawg ± 4kv hluav taws xob ceev ceev cov mem tes pab pawg (eft), nrog rau 3v / m high-frequency electromagnetic teb cuam tshuam, 300a / m muaj zaus magnetic teb cuam tshuam. Ntau yam ntawm AC input voltage, kom lub zog hloov hluav taws xob tuaj yeem ua haujlwm ib txwm tom qab kev cuam tshuam ntawm qhov poob qis, qhov hluav taws xob hloov pauv thiab cuam tshuam luv luv ntawm qhov hluav taws xob ntawm tag nrho lub tshuab. Qhov cuam tshuam qhov hluav taws xob ntawm daim phiaj hluav taws xob los ntawm thoob plaws lub tebchaws tau raug txheeb xyuas thiab tshuaj xyuas ntawm ZTE hloov hluav taws xob.
Electromagnetic compatibility indexes ntawm ZTE series hloov fais fab mov tau ua tiav tag nrho thiab tshaj qhov ntsuas ntawm txhua yam khoom tau teev tseg hauv yd/t983-1998 Electromagnetic Compatibility Requirements thiab Measurement Methods for Communication Switching Power Supply Equipment, thiab qee cov khoom tau dhau los. daim ntawv pov thawj ce thiab tag nrho cov electromagnetic compatibility indexes nyob rau hauv daim ntawv pov thawj fcc, uas yog ib tug tiag tiag environmentally phooj ywg hloov fais fab mov rau kev sib txuas lus, tshwj xeeb tshaj yog haum rau mobile base chaw nres tsheb, cov kev pab cuam noj, thiab lwm yam kev siv fais fab mov. Tshwj xeeb tshaj yog tsim nyog rau lub hauv paus chaw nres tsheb, kev tswj kev hloov khoom siv, ip xov tooj, cable TV thiab lwm yam ntaub ntawv kev sib txuas lus cov khoom, raws li zoo raws li railways, hydropower, thermal hwj chim noj thiab lwm yam muaj zog electromagnetic teb cuam tshuam lub sij hawm.
