A: Pali 2 Matanthauzidwe Apa Apa:
(1) Chifukwa chiyani chiwongola dzanja chili choyipa (ndiye, malo abwino)?
(2) Chifukwa chiyani magetsi -48V (-36~ -72v)?
Tiye tikambirane funso lachiwiri. Kugwiritsa ntchito magetsi a -48V ndi zifukwa zakale. Kulankhulidwa koyambirira kogwiritsa ntchito ndi mafoni, Telefoni imayendetsedwa ndi telefoni, ndi 48V amasankhidwa pomwe
Onjezani mtunda kuchokera kwa wosuta kupita ku ofesi yomaliza kwambiri momwe mungathere pansi pazomwe zilipo (36V ndi magetsi otetezeka, Zochulukirapo ndizosavomerezeka). Osati pano, Pofuna kukhala ogwirizana ndi zida zoyambirira ndikuchepetsa mtengo, Zida zolumikizirana zapakati zimagwiritsira ntchito - 48v mphamvu zamagetsi.

Chimodzimodzi, ndi mphamvu yoyipa, Malo abwino ndi msonkhano chabe. Zimapezeka kuti pali zolipiritsa zambiri mlengalenga. Malinga ndi chidziwitso cha electrochemical, Kuyika koyenera kumatha kuyamwa mayoke oyipa mlengalenga, potero kuteteza kulamula kwa zida zam'manja kuchokera ku zono. Pamenepo, Izi sizolondola. Zochita za Alvanic ndi Electrolytic zimatha kuyambitsa zida ma dzimbiri, Koma chifukwa amakhala ndi mawonekedwe a microscopic pa zida, alibe mphamvu. Mwachitsanzo, ma network a njira yosayankhulana yopanda tanthauzo (monga kompyuta yomwe mukugwiritsa ntchito), koma sikuti. Kuphatikiza apo, A -4V amapatula ndi DC / DC. Kutulutsa kwa DC / DC ndiye choyipa, ndipo woweta sakuwonongeka kapena wokhazikika. Kotero ziribe kanthu kuti mtengo uti womwe wakhazikika, ndizofanana.

Monga kukhazikitsidwa kwa chipolopolo cha zida (yolumikizidwa ndi PGN), Izi ndi cholinga choteteza, Ndipo mlandu wamagetsi womwe umapezeka pa zida amatumizidwa mwachangu pansi, kotero kuti musawononge zida ndi ndodo.
Zogulitsa zathu zimagwiritsa ntchito njira ya -48v mphamvu, ndi vodzi yeniyeni yoyesedwa nthawi zambiri --53.5V. Izi ndichifukwa choti chifukwa chodalirika, Zida zoyankhulirana zili ndi batiri losunga (-48v). Pofuna kuonetsetsa kuti kulimitsa batri, Mphamvu yamagetsi imayenera kukhala yokwera pang'ono kuposa batri ya batri.

Muthanso kuphunziranso pa media yomwe pali zida zomwe zimagwiritsa ntchito njira ya -24v mphamvu, zomwe zida zamakono zamakono zimagwiritsa ntchito zotheka. Mphamvu yotulutsa mphamvu yamphamvu nthawi zambiri imayesedwa kuti ikhale 26.8V.
Mwazonse, Zida zimafunikira kugwira ntchito nthawi zambiri mkati mwa mitundu yamagetsi ya ± 20%. Zida za -48V, Mitundu yamagetsi imakhala -38.4V ~ 57.6V, Koma nthawi zambiri timafuna ntchito -36v ~ -72V. Kuganizira kwakukulu ndikuti -48V zida zamagetsi ziyenera kukhala zogwirizana ndi dongosolo la magetsi, zomwe zimafuna -48 ~ -72V. Mwa njira iyi, kuphatikiza kumafunikira kuti mugwire ntchito yamagetsi yamagetsi ya -36v ~ -72V.
Ndisanayiwale, Dongosolo la -48V lamphamvu limangokhala ndi mphamvu yolankhulirana yomwe ili ndi dziko langa komanso mayiko ambiri. Si mayiko onse omwe amagwiritsa ntchito muyeso uwu. Mwachitsanzo, Russia imagwiritsa ntchito makina a -60v magetsi, Ndipo mayiko ena amagwiritsa ntchito njira ya -24v mphamvu. Ngati malonda agulitsidwa m'magawo awa, ndikofunikira kuganizira izi.

Muyezo wa Mphamvu Maulamuliro ndi osiyananso padziko lapansi. Mwachitsanzo, Dziko langa ndi Europe Gwiritsani ntchito dongosolo la 220V, ndi United States ndi Japan Gwiritsani ntchito 110V Main.
Pezani malongosoledwe chifukwa chifukwa chake nthaka yabwino ndi yochokera ku chidziwitso cha Huawei, Monga kufotokoza kowonjezera:
Kukhazikika koyenera kumalepheretsa kusefukira kwa electrode. The -4V kapena -24V Coutriter Coutriter Office ya Telefoni imakhazikika pamtengo wabwino. Chifukwa chake ndikuchepetsa chigwa chamagetsi chomwe chimayambitsidwa ndi chisamaliro chosauka cha chinsinsi kapena chikho, zomwe zingawononge cholumikizira komanso chikho cha chikho. Chifukwa nthawi ya electrolytic, Chitsulo chachitsulo chimasuntha kuchokera ku electrode yoyatsira ma electrode osavomerezeka pansi pa mankhwala. Kutumula pakati pa coil ndi core core ndi osauka, ndi maulendo ochepa. Pomwe ma electrode oyipa a phukusi la batri, waya wa coil amatha kuwonongeka. M'malo mwake, Ngati mtengo wake wamtengo wa batri, Ngakhale maziko achitsulo azikhalanso ndi magetsi, waya wa coil sadzalamulira, ndi mtundu wa core yachitsulo ikhale yayikulu, zomwe sizingapangitse zokumana nazo. Kukhazikika koyenera kumatetezanso maaya ang'ono a chinsinsi chakunja kuchokera ku kututa pamene kusokonekera. (Zindikirani: Mkhalidwe wabwino ndikuti kulumikizana komwe kumachitika)
