POE Simba pamusoro peEthernet yekudzivirira yekudzivirira

Kuvandudzwa kweSimba pamusoro peEthernet (POE) tekinoroji yakasimba kwazvo. Kuvandudzwa kweiyi tekinoroji kunogona kurerutsa kugadzwa uye kutumirwa kwemidziyo yemagetsi, nokudaro kubvisa kudiwa kwetambo dzakazvimirira dzekufambisa. Mazuva ano, tekinoroji yemagetsi (POE) inoshandiswa zvakanyanya mumaindasitiri masisitimu akadai sekuchengetedza, kutaurirana, uye smart grids kuti uwane data, kutapurirana kwevhidhiyo, kuyerera kwekudzora, uye kugovera magetsi kuburikidza nemabhazi mukati mehurongwa. Nekudaro, nekuda kwenzvimbo yekushanda yakaoma yeIndustrial Ethernet, kuvhiya uye kuchengetedzwa kwakamira kwePOE port kwakakosha. Heino sumo pfupi yekudzivirira chirongwa chePOE system:
Level:
(1) IEC61000-4-2: LEVEL4: Bata 8kV; Mhepo: 15kV
(2) IEC61000-4-5: 10/700us LEVELX: 6KV
Nheyo: Zvirongwa zviviri zviri pamusoro zvinotora musanganiswa wezviviri-matanho ekudzivirira, nedanho rekumberi riri electrostatic silicon suppressor SET uye negative clamp voltage suppressor NVCS, kutora nekuburitsa simba rekuvhiya. Iyo yekumashure nhanho yekudzivirira mudziyo ndeye electrostatic dziviriro ESD, ine chaiyo clamp voltage uye nekukurumidza kuita kukurumidza, Bvisa simba rakasara redanho rapfuura, dzikisa voltage kusvika mukati meiyo dhizaini yekumashure inogona kumira, uye chengetedza kumashure- end chip. Mune echinyakare 48V magetsi ekudzivirira ekudzivirira, mamwe maturusi ekudzivirira anoshandiswa kuvandudza nhanho yekuyedza, iyo inogara vhoriyamu yakakura uye ine hurombo hunodzora mhedzisiro pane yasara voltage, zvichikonzera kuwedzera mukana wekudzokera-kumagumo chip kukuvara. Nechikonzero ichi, SPSEMI Instant Thunder Electronics yakagadzira yakashata clamp voltage suppressor NVCS yakatevedzana zvinhu zvakanangana nePOE (48V magetsi). Ichi chinyorwa chine chiyero chikuru chekuyerera uye vhoriyamu diki, iyo yakaiswa muSMC. Panyaya yekusarira magetsi ekudzora, inenge 20V yakaderera pane yechinyakare TVS zvinhu, izvo zvinogona kunyatso chengetedza kumashure-kumagumo chip.

Nheyo: Zvirongwa zviviri zviri pamusoro zvinotora dziviriro yezvikamu zviviri. Iyo yekumberi nhanho ndeye negative clamp voltage suppressor NVCS, inotora uye kuburitsa hombe simba rekuwedzera. Iyo yekumashure nhanho yekudzivirira mudziyo ndeye electrostatic inodzivirira ESD, ine chaiyo clamping voltage uye nekukurumidza kuita kukurumidza. Inotora simba rakasara rechikamu chepamberi, inoderedza voltage kusvika mukati mehuwandu iyo iyo yekumashure-yekupedzisira dunhu inogona kumira, uye inodzivirira kumashure-kuguma chip.
Zvinoenderana neyakajairwa chiyero chepasi rose IEC61000-4-5, simba rekumhanya kwemheni rinowanzo jekiseni nenzira yakajairika. Mukugadzirwa kwechirongwa, kutarisa kunobhadharwa kune common mode kuchengetedzwa. Electrostatic dziviriro TUSD03FB inowedzerwa pakati pemitsetse yakasarudzika yekusiyanisa modhi yekudzivirira, ichibvisa iyo yakasara simba yakabatana neshure kumagumo panguva yekurova kwemheni, uye kudzivirira mutsauko wekumanikidza pakati pemitsara kubva pakuchinja. Chirongwa chekudzivirira chiri pamusoro chakasimbiswa neSPSEMI Transient Thunder Electronics Laboratory.
Izvo zviri pamusoro ipfupi pfupiso yePOE Simba pamusoro peEthernet Surge Dziviriro, iyo inogona kushanda sereferensi kune wese munhu. Kambani yedu ine yakasimba tekinoroji timu uye inogona kupa nyanzvi tekinoroji masevhisi kune vatengi. Parizvino, kambani yedu ine zvigadzirwa zvakasiyana-siyana: zvakangwaraonu, kutaurirana Optical module, optical fiber module, sfp Optical module,oltmidziyo, Ethernetchinjanemimwe michina yetiweki. Kana uchida, unogona kuva nokunzwisisa kwakadzama.
