Inverter Pow Sopy yeZixhobo zoNxibelelwano Ikakhulu i-Voltge yi-48VDC

Isizathu sembali：

Uthungelwano lokuqala lonxibelelwano olusetyenziswayo luthungelwano lwemfonomfono, 48I-Vdc ikhethiwe ukunyusa umgama phakathi komsebenzisi kunye ne-ofisi yokugqibela phantsi kweemeko zangoku (36V ngumbane okhuselekileyo, kwaye akukhuselekanga ukuba i-voltage idlula kakhulu). ukuze ihambelane nezixhobo zakwangoko kunye nokunciphisa iindleko, izixhobo zonxibelelwano lwasekhaya zisasebenzisa umbane we-48V.

Ngokufanayo, ngenkqubo yamandla engalunganga, isiseko esihle yindibano. Kukho intetho yakudala ethi kukho intlawulo eninzi embi emoyeni, kwaye isekelwe kulwazi lwe-electrochemical, Isiseko esihle sinokufunxa ii-ion ezingalunganga emoyeni, ngaloo ndlela ikhusela i-casing yezixhobo zonxibelelwano ekudlekeni. Ngokwenene, akulunganga oko. Ukusabela kwe-galvanic kunye ne-electrolysis reaction kunokukhokelela kwi-rust yezixhobo, kodwa ngenxa yokuba zikhona kwifom ye-microscopic kwisixhobo, kukho impembelelo encinci. Umzekelo, uthungelwano lweenkqubo ezingezizo ezonxibelelwano zisekelwe kakubi (njengekhompyuter oyisebenzisayo), kodwa azivuthwanga. Ukwengeza, -48U-V ubekwe yedwa nge-DC/DC, kunye nemveliso ye-DC/DC ngumhlaba ongalunganga, kwaye ibhodi ayinamhlwa kwaye ayinamhlwa. Ngoko kungakhathaliseki ukuba yeyiphi ipali esekelwe phantsi, iyafana.

I-Bwitt inverter isebenzisa inkqubo yonikezelo lwamandla -48V, kwaye owona mbane ulinganiswe ngokubanzi ngu-53.5V. Ngenxa yokuthembeka, izixhobo zonxibelelwano zineebhetri ezisecaleni (-48V). Ukuqinisekisa ukutshaja okuthembekileyo kweebhetri, amandla ombane kufuneka abe phezulu kancinci kunombane webhetri.

Ubumbeko olufanelekileyo:

Ngokubanzi, isixhobo kufuneka sisebenze ngokwesiqhelo phakathi koluhlu lokuguquguquka kwamandla ombane ±20%. Kwi- -48V izixhobo zenkqubo ziyafuneka ukuba zisebenze kuluhlu lwamandla ombane -38.4V ~ 57.6V, kodwa eneneni sifuna ngokubanzi uluhlu olusebenzayo lwe -36V ~ -72V.

Ikakhulu kuqwalaselwa ukuba izixhobo zenkqubo -48V kufuneka zihambelane nenkqubo yamandla -60V, efuna -48 ~ -72V. Ngele ndlela, iseti iyadingeka ukuba isebenze kuluhlu lwe-voltage malunga -36V ~ -72V. Ngokubanzi, kungakhathaliseki ukuba i-voltage iphezulu kangakanani, ayikhuselekile kwaye ineemfuno eziphezulu kwinqanaba le-insulation yekhebula. Kwimekobume efumileyo, ukuqhekeka kulula ukwenzeka. Umsinga uphantsi kakhulu ukuba ufanelekile. Ukwengeza, kuthathelwa ingqalelo inkqubo yonikezelo lwamandla olungaphazanyiswa usebenzisa iibhetri ze-lead-acid, 48U-V nguye kanye 12 2V iiseli zebhetri, kunye nenkqubo yomthamo omncinci usebenzisa iibhetri ze-12V, ezine kuphela. Inani elifanelekileyo leentambo zebhetri kulula ukulinganisa. Kufuphi, sisiphumo sokuqwalaselwa okubanzi.

Kwi- -48V inverter inkqubo yonikezelo lwamandla, i-AC mains ayiqwalaselwanga kakuhle kwaye iguqulelwe kwi-54.5-55V DC ngokusebenzisa unikezelo lwamandla okutshintsha ukudada ibhetri kunye nokubonelela ngamandla kwisixhobo ngaxeshanye.. Ilula kwaye icacile.

Amandla ombane angama-54V okanye ngoko amiselwa ikakhulu ngumbane wentlawulo edadayo yebhetri ye-lead-asidi, malunga ne-2.2V kwiseli nganye. Ukuqwalasela iqonga lokutshaja kunye nokukhupha ibhetri, olona luhlu lwamandla ombane oluvumelekileyo lwesixhobo lubanzi ngokubanzi, ukusuka -40V ukuya -57V.

-48I-V inverter kwinkqubo yonikezelo lwamandla ngumgangatho wobonelelo lwamandla onxibelelwano olwamkelwa ngamazwe amaninzi. Ayingawo onke amazwe asebenzisa lo mgangatho. Umzekelo, IRashiya isebenzisa inkqubo yonikezelo lwamandla -60V, kwaye amanye amazwe asebenzisa -24V inkqubo yonikezelo lwamandla.
