Cov xwm txheej tam sim no ntawm electromagnetic compatibility txhim kho kev sib txuas lus hauv tsev hloov cov khoom siv hluav taws xob
Txij li thaum tus qauv YD / T983 tau tsim los, cov tuam txhab kev sib txuas lus hauv tsev tau pib tshawb fawb txog electromagnetic compatibility. Txij li thaum kev tsim kho cov cuab yeej siv hluav taws xob sib xyaw ua ke thiab cov chaw sim yog kim heev thiab xav tau cov neeg ua haujlwm R & D, ntau lub tuam txhab tsis muaj lawv tus kheej lub chaw soj nstuam, uas ua rau qee qhov teeb meem hauv kev tshawb fawb electromagnetic compatibility. Nyob rau hauv tus qauv yd/t983, qhov ntsuas kev tiv thaiv kab mob tau txais qib qis hauv cov qauv txawv teb chaws. Tsuas yog cov ntsuas hluav taws xob surge, 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 kev cuam tshuam kev cuam tshuam thiab hluav taws xob cuam tshuam, tam sim no yog lub ntsiab lus kub hauv kev tshawb fawb electromagnetic compatibility vim tias nws nyuaj rau ua kom tau raws li cov qauv. Tsuas yog ib tug puv tes ntawm domestic manufacturers tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov qauv tsim nyog.
ZTE tau tsim nws tus kheej electromagnetic compatibility laboratory thiab tau cog lus rau electromagnetic compatibility kev tshawb fawb nyob rau hauv thaum ntxov theem ntawm kev tshawb fawb thiab kev loj hlob ntawm kev sib txuas lus hloov cov khoom siv fais fab. Cov theem pem hauv ntej ntawm nws cov kev sib txuas lus hloov hluav taws xob siv lub zog siv hluav taws xob zoo tshaj plaws kho thev naus laus zis thiab tsis muaj kev nqus hluav taws xob, thiab cov theem tom qab DC / DC txais yuav xoom voltage xoom tam sim no (zvzcs) theem hloov resonance mos hloov tshuab lossis dual-tube rau pem hauv ntej lossless. absorption soft switching. Technology, los ntawm kev tshaj lij fais fab kev tawm tswv yim thiab tso zis lim tsim thiab kev tiv thaiv xob laim tsim, nrog rau kev nyab xeeb ntawm tag nrho lub tshuab, tiv thaiv zoo li qub tsim ntawm digital interface circuits thiab anti-ceev hloov pulse pab pawg tsim, thiab tsim nyog electromagnetic shielding tsim rau tag nrho. tshuab qauv, Nws tsis tsuas yog ua rau lub electromagnetic ib puag ncig nyob rau hauv tag nrho cov tshuab zoo, lub lag luam yog ruaj khov, thiab kev ntseeg tau zoo dua, tab sis kuj lub sab nraud tam sim no harmonics, hluav taws xob fluctuations thiab flickers, conduction cuam tshuam thiab hluav taws xob cuam tshuam ntawm kev sib txuas lus hloov fais fab mov. ua tau raws li lossis tshaj qhov yuav tsum tau ua hauv Chav A uas tau teev tseg hauv tus qauv cispr22. Lub tswv yim AC fais fab kab tuaj yeem tiv taus yam tsawg ± 6kv (ua ke nthwv dej ntawm 1.2/50μs thiab 8/20μs) surge voltage cuam tshuam, DC fais fab kab tuaj yeem tiv taus yam tsawg ± 2kv surge voltage; sab nraud ntawm lub tshuab tuaj yeem tiv taus yam tsawg kawg nkaus ± 8kv electrostatic paug (esd) cuam tshuam, hluav taws xob ceev ceev cov mem tes pab pawg (eft) tsawg kawg yog ± 4kv, nrog rau cov hluav taws xob hluav taws xob ntau zaus ntawm 3v / m, thiab lub zog zaus sib nqus Teb cuam tshuam ntawm 300a / m. Qhov dav AC input voltage ntau ua rau lub zog hloov hluav taws xob ua haujlwm ib txwm ua tom qab muaj kev cuam tshuam xws li kev poob qis, kev hloov pauv hluav taws xob, thiab kev cuam tshuam luv luv ntawm tag nrho lub tshuab. Daim phiaj hluav taws xob cuam tshuam qhov hluav taws xob uas tau sau los ntawm thoob plaws lub tebchaws tau raug txheeb xyuas thiab tshuaj xyuas ntawm ZTE hloov cov khoom siv hluav taws xob.
