POE Imbaraga hejuru ya Ethernet kurinda

Iterambere ryimbaraga hejuru ya tekinoroji ya Ethernet (POE) irakomeye cyane.Iterambere ryikoranabuhanga rirashobora koroshya kwishyiriraho no kohereza ibikoresho byamashanyarazi, bityo bikuraho gukenera imirongo yigenga.Muri iki gihe, tekinoroji yo gutanga amashanyarazi (POE) ikoreshwa cyane muri sisitemu y’inganda nkumutekano, itumanaho, hamwe na gride yubwenge kugirango igere ku makuru, kohereza amashusho, kugenzura imiyoboro, no gutanga amashanyarazi binyuze muri bisi ziri muri sisitemu.Ariko, kubera ibidukikije bikora bya Ethernet yinganda, kwiyongera no kurinda umutekano icyambu cya POE ni ngombwa.Dore intangiriro ngufi kuri gahunda yo kurinda sisitemu ya POE:
Urwego:
(1) IEC61000-4-2: LEVEL4: Menyesha 8kV;Umuyaga: 15kV
(2) IEC61000-4-5: 10 / 700us URWEGO: 6KV
Ihame: Gahunda ebyiri zavuzwe haruguru zemeza uburyo bwo kurinda ibyiciro bibiri, icyiciro cyambere kikaba icyuma cya electrostatike silicon suppressor SET hamwe na clamp voltage clamp voltage NVCS, kugirango ikure kandi irekure ingufu nini zo kwiyongera.Igikoresho cyo kurinda icyiciro cyinyuma nicyuma gikingira amashanyarazi ya ESD, hamwe na voltage ya clamp itomoye hamwe nihuta ryihuta, Absorb ingufu zisigaye zicyiciro kibanziriza iki, gabanya voltage kugeza murwego umuzenguruko winyuma ushobora kwihanganira, kandi ukarinda inyuma- chip.Mubisanzwe birinda amashanyarazi ya 48V, ibikoresho byinshi birinda bikoreshwa mugutezimbere urwego rwo kwipimisha, rufite umwanya munini kandi rukagira ingaruka mbi zo kugenzura kuri voltage isigaye, bigatuma habaho kwiyongera kwangirika kwinyuma.Kubera iyo mpamvu, SPSEMI Instant Thunder Electronics yakoze ibikoresho bibi bya clamp voltage suppressor ya NVCS ibikoresho byumwihariko kuri POE (amashanyarazi 48V).Ibi bikoresho bifite umuvuduko munini nubunini buto, bipakiye muri SMC.Kubijyanye no kugenzura ibisigisigi bya voltage isigaye, ni munsi ya 20V munsi yibikoresho bya TVS gakondo, bishobora kurinda neza chip yinyuma.

(2) IEC61000-4-5: 10 / 700us URWEGO: 6KV
Ihame: Gahunda ebyiri zavuzwe haruguru zifata ibyiciro bibiri byo kurinda.Icyiciro cyimbere ni clamp voltage voltage suppressor NVCS, ikurura kandi ikarekura ingufu nini zo kwiyongera.Igikoresho cyo gukingira icyiciro cyinyuma nicyuma gikingira amashanyarazi ESD, gifite voltage yuzuye neza kandi yihuta.Ikuramo imbaraga zisigaye zicyiciro cyimbere, igabanya voltage kugeza murwego uruziga rwinyuma rushobora kwihanganira, kandi rukarinda chip yinyuma.
Ukurikije amahame mpuzamahanga ya IEC61000-4-5, ingufu zumurabyo ziterwa muri rusange muburyo bumwe.Mu gishushanyo mbonera, hitabwa cyane kuburinzi busanzwe.Kurinda amashanyarazi TUSD03FB yongewe hagati yumurongo wigunze kugirango ukingire uburyo butandukanye, ukuraho ingufu zisigaye zifatanije nu mpera yinyuma mugihe cyo gukubita inkuba, no kurinda itandukaniro ryumuvuduko uri hagati yumurongo guhinduka.Gahunda yo kurinda yavuzwe haruguru yagenzuwe na Laboratoire ya SPSEMI Transient Thunder Electronics.
Ibyavuzwe haruguru ni incamake yimbaraga za POE hejuru ya Ethernet Surge Kurinda, ishobora kuba nkibisobanuro kuri buri wese.Isosiyete yacu ifite itsinda rikomeye rya tekiniki kandi irashobora gutanga serivisi tekinike yumwuga kubakiriya.Kugeza ubu, isosiyete yacu ifite ibicuruzwa bitandukanye: onu ifite ubwenge, itumanaho Optical module, optique ya fibre optique, sfp Optical module, ibikoresho bya olt, Ethernet switch nibindi bikoresho byurusobe.Niba ukeneye, urashobora gusobanukirwa byimbitse.
