A: Pane 2 Zvinoreva pano:
(1) Nei iyo polarity isina kunaka simba (ndiko, Gadzirisa Nzvimbo)?
(2) Nei iyo voltage -48V (-36~ -72V)?
Ngatitaurei nezve mubvunzo wechipiri kutanga. Uchishandisa -48V Simba Simba ndeyezvikonzero zvezvakaitika kare. Iyo yekutanga kutaurirana network inoshandiswa iyo foni network, Runhare rwunopihwa neTelecompunication Bureau, uye 48v inosarudzwa kana iyo
Wedzera chinhambwe kubva kune mushandisi kuenda kuhofisi yekupedzisira zvakanyanya sezvinobvira pasi pemamiriro ezvinhu azvino (36V inzvimbo yakachengeteka, zvakawandisa hazvina kuchengetedzeka). Gare gare, Kuti uenderane nemidziyo yekutanga uye kuderedza mitengo, Iyo Central Hoffication yekukurukurirana midziyo ichiri kushandisa -48V Simba Kuwanikwa.

Saizvozvowo, nehurongwa husina kunaka hwemagetsi, Iyo yakanaka ivhu ingori kokorodzano. Zvinozoitika kuti kune huwandu hukuru hwezvakaipa zvakashata mumhepo. Zvinoenderana nezivo yeElectrochemical, Iyo yakanaka nzvimbo inogona kutora zvisina kunaka ion mumhepo, nokudaro vachidzivirira kushandurwa kwefoni yefoni kubva kuCorrosion. Saizvozvo, Ichi chirevo hachina kunyatsojeka. Gallanic uye electrolytic maitiro anogona kukonzera zvishandiso kuti ngura, asi nekuti ivo varipo muMicroscopic fomu pamidziyo, Ivo vane zvishoma maitiro. Semuyenzaniso, Network yeiyo isiri-yekukurukurirana system haina kunaka pasi (sekombuta yauri kushandisa), asi haina kunyara. Pamusoro pe, Iyo -48V inoiswa ichiparadzaniswa ne dc / DC. Iyo dc / dc kubuda ndeye iyo yakaipa pasi, uye mutengesi haana kugadzirwa kana kuti akaomarara. Saka zvisinei nekuti pole yakagadziriswa, zvakafanana.

Kana iri yekuvhurwa yeganda remidziyo (yakabatana nePGNG), Izvi ndezve chinangwa chekudzivirira, uye iyo yemagetsi kubhadharwa kwakaunganidzwa pamidziyo inokurumidza kudzingwa pasi, kuitira kuti usakuvadza zvishandiso nevashandi.
Zvigadzirwa zvedu zvakangoitika zvinoshandisa A -48V Simba SWOUCY SHEMA, uye iyo chaiyo voltage yakayerwa inowanzoitika -53.5V. Izvi zvinodaro nekuti nekuda kwekuvimbika, Midziyo yekutaurirana ine backup bhatiri (-48v). Kuti uve nechokwadi chekubhadhara kwakavimbika kwebhatiri, Iyo Power Supply Voltage inoda kuve yakakwira zvishoma kupfuura bhatiri voltage.

Iwe unogona zvakare kudzidza kuburikidza nenhau kuti pane zvigadzirwa zvinoshandiswa A -44V magetsi ekuisa system, izvo zvimwe zvemukati zvemukati zvishandiso zvinoshandiswa pakugadzira nyore. Iyo yekubuditsa voltage yeiyo simba inowanikwa inowanzo kuyerwa kuve 26.8V.
Kazhinji, Midziyo inodikanwa kuti ishande kazhinji mukati meiyo voltage crauctuation renji ye ± 20%. For -48v system, Iyo inoshanda voltage range is -38.4v ~ 57.6v, Asi isu kazhinji tinoda iyo inoshanda huwandu -36v ~ -72V. Iko kukuru kufunga ndeyekuti iyo -48V system michina inofanirwa kuenderana ne -60V simba rekupa system, izvo zvinoda -48 ~ -72V. Nenzira iyi, Iko kusanganiswa kunodiwa kuti ushande mune voltage range of About -36V ~ -72V.
Zviya, Iyo -48V Simba Simba rekupa system ingori chete Simba Simba Simba rekupa standard nyika uye nyika zhinji. Haasi nyika dzese dzinoshandisa iyi mwero. Semuyenzaniso, Russia inoshandisa -60v simba rekugovera system, uye dzimwe nyika dzinoshandisa A -24V Simba Simba Simba. Kana chigadzirwa chiri kutengeswa mumatunhu aya, Izvo zvinodikanwa kuti uzive izvi zviyero zvakasiyana.

Maitiro eSES SIMBA Simba zvakare rakasiyana munyika. Semuyenzaniso, Nyika yangu uye Europe Shandisa 220V Mains system, uye United States neJapan Shandisa 110V mains.
Tsvaga tsananguro yekuti nei iyo yakanaka nzvimbo iri kubva kuHuawei ruzivo rwaHuawei, setsananguro yekuwedzera:
Iyo nzvimbo yakanaka ndeye kunyanya kudzivirira iyo kuenderana kweiyo electrode. The -48v or -24V bhatiri pakiti yehofisi yefoni yakagadziriswa pane yakanaka danda. Chikonzero ndechekuderedza iyo yemagetsi corrosion inokonzerwa nekuvhenekera kwekunyora kweiyo rondedzero kana iyo simbi sheath yetambo, izvo zvichakuvadza dzidziso uye simbi sheath yetambo. Nekuti panguva yeElectrolytic Corrosion, Iyo simbi ions inofamba kubva kune yakanaka electrode kune isina kunaka electrode pasi peMakemikari maitiro. Iyo insulation pakati peiyo yerudzi rwekudzokorora uye iyo iron core iri murombo, uye chidiki chidiki chinoyerera. Kana iyo isina kunaka electrode yebhatiri pakiti yakadzika, waya yeiyo coil inogona kunge yakagadziriswa. Pane zvinopesana, Kana danda rakanaka rebhatiri pack rakavharwa, Kunyangwe iyo simbi core ichave zvakare ichitarisana neyemagetsi corrosion, waya yeiyo coil haizo corrode, uye kunaka kweiyo simbi core ichave yakakura, Izvo hazvizotungamira kumhedzisiro inooneka. Kuvapo kwakanaka zvakare kunodzivirirawo waya mairi wengarava rekunze kubva kuCorrosion kana iyo Insulation iri murombo. (ONA: Mamiriro akazara ndewekuti iyo nzira yekudzoka yakadzika)
