800V ikibazo cya sisitemu: kwishyuza ikirundo cya sisitemu yo kwishyuza

800V Kwishyuza ikirundo "Kwishyuza Ibyingenzi"

Iyi ngingo ivuga cyane cyane kubisabwa mbere ya 800Vkwishyuza ibirundo, ubanza reka turebe ihame ryo kwishyuza: Iyo inama yo kwishyuza ihujwe nimpera yikinyabiziga, ikirundo cyumuriro kizatanga (1) imbaraga zingufu za DC zingufu za DC kumpera yikinyabiziga kugirango ukoreshe BMS yubatswe (sisitemu yo gucunga bateri) yimodoka yamashanyarazi Nyuma yo gukora, (2) guhuza impera yimodoka kugeza kumpera yikigereranyo cyimbaraga zishyirwaho nkibintu byinshi bisabwa kwishyurwa nkibintu byinshi bisabwa kwishyurwa nkibintu byinshi bisabwa kwishyurwa nkibintu byinshi bisabwa kwishyurwa nkibintu byinshi bisabwa kwishyurwa nkibintu byinshi bisabwa kwishyurwa nkibintu byinshi bisabwa kwishyurwa nkibintu byinshi byishyurwa byimbaraga zishyirwaho nkibintu byinshi bisabwa kwishyurwa nkibintu byinshi byanyuma bihuye neza, BMS (sisitemu yo gucunga bateri) yimodoka yanyuma izohereza amakuru asaba ingufu kurisitasiyo yumuriro, naamashanyarazi yamashanyaraziAzahindura ibyasohotse mumashanyarazi hamwe nubu ukurikije aya makuru, hanyuma atangire kwishyuza kumugaragaro imodoka, nihame shingiro ryakwishyuza, kandi dukeneye kubimenyera mbere.

Kwishyuza 800V: “ongera imbaraga za voltage cyangwa ikigezweho”

Mubyukuri, niba dushaka gutanga imbaraga zo kwishyuza kugirango tugabanye igihe cyo kwishyuza, mubisanzwe hariho inzira ebyiri: ushobora kongera bateri cyangwa kongera ingufu za voltage; Ukurikije W = Pt, niba imbaraga zo kwishyuza zikubye kabiri, igihe cyo kwishyuza kizaba kabiri; Ukurikije P = UI, niba voltage cyangwa umuyoboro wikubye kabiri, ingufu zumuriro zirashobora gukuba kabiri, byavuzwe inshuro nyinshi kandi bifatwa nkibisanzwe.

Niba ikigezweho ari kinini, hazabaho ibibazo bibiri, binini bigezweho, binini na bulkier insinga isaba amashanyarazi, izongera diameter ya wire nuburemere, byongere igiciro, kandi ntibyoroshye abakozi gukora; Byongeye kandi, ukurikije Q = I²Rt, niba ikigezweho ari kinini, igihombo cy’amashanyarazi ni kinini, kandi igihombo kigaragarira mu buryo bw’ubushyuhe, ari nacyo cyongera umuvuduko w’imicungire y’ubushyuhe, bityo rero ntagushidikanya ko atari byiza kongera ingufu zumuriro ukomeza kongera amashanyarazi, yaba yishyuza cyangwa sisitemu yo gutwara imodoka.

Ugereranije nubushakashatsi bwihuse-bwihuse,umuriro mwinshi cyaneitanga ubushyuhe buke no gutakaza igihombo, kandi hafi yimodoka zisanzwe zimodoka zafashe inzira yo kongera ingufu za voltage, mugihe habaye umuriro mwinshi mwinshi, mubyukuri ko igihe cyo kwishyurwa gishobora kugabanywa na 50%, kandi kwiyongera kwa voltage nabyo bishobora kongera ingufu zumuriro kuva 120KW kugeza 480KW.

Kwishyuza 800V: “Ingaruka ziterwa nubushyuhe bujyanye na voltage nubu”

Ariko niba ari ukongera ingufu za voltage cyangwa kongera amashanyarazi, mbere ya byose, hamwe no kongera imbaraga zumuriro wawe, ubushyuhe bwawe buzagaragara, ariko kwigaragaza kwubushyuhe bwo kongera voltage no kongera amashanyarazi biratandukanye. Ariko, iyambere irakunzwe ugereranije.

Bitewe nuburwanya buke bwahuye nubu nubu iyo unyuze mumashanyarazi, uburyo bwo kongera ingufu za voltage bugabanya ingano ya kabili isabwa, kandi ubushyuhe bugomba gukwirakwizwa ni buke, kandi mugihe ikigezweho cyiyongereye, ubwiyongere bwikibanza gitwara ibice byambukiranya ibice biganisha kuri diameter nini yo hanze nuburemere bunini bwa kabili, kandi ubushyuhe bugenda bwiyongera buhoro buhoro hamwe no kwagura igihe cyo kwishyuza, bikaba byihishe cyane kuri batiri.

Kwishyuza 800V: “Ibibazo bimwe byihutirwa hamwe no kwishyuza ibirundo”

800V yishyuza byihuse nayo ifite ibisabwa bitandukanye kuruhande rwikirundo:

Niba ukurikije ibintu bifatika, hamwe no kwiyongera kwa voltage, ingano yubushakashatsi bwibikoresho bifitanye isano igomba kwiyongera, kurugero, ukurikije urwego rw’umwanda wa IEC60664 ni 2 naho intera y’itsinda ry’ibikoresho byo mu bwoko bwa insulasiyo ni 1, intera y’ibikoresho bikoresha amashanyarazi menshi igomba kuba kuva kuri 2mm ikagera kuri 4mm, kandi n’ibisabwa kugira ngo ibishushanyo mbonera bigomba gukenerwa kugira ngo habeho ibishushanyo mbonera bigomba gukenerwa kugira ngo bibe byateganijwe kugira ngo bibe byateganijwe kugira ngo bibe byateganijwe kugira ngo bikorwe, harimo umuhuza, utubari twumuringa, umuhuza, nibindi. Byongeye kandi, kwiyongera kwa voltage bizanatuma ibisabwa bisabwa kugirango kuzimya arc, kandi birakenewe kongera ibisabwa kubikoresho bimwe na bimwe nka fus, agasanduku ko guhinduranya, guhuza, nibindi, nabyo bikurikizwa mugushushanya imodoka, bizavugwa mu ngingo zikurikira.

Sisitemu yo kwishyuza hejuru ya 800V ikeneye kongeramo sisitemu yo gukonjesha ikora hanze nkuko byavuzwe haruguru, kandi gukonjesha ikirere ntigishobora kuzuza ibisabwa niba ikora cyangwa ikonje gusa, hamwe nubuyobozi bwubushyuhe bwasitasiyo yumuriro wamashanyaraziumurongo wimbunda kugera kumpera yikinyabiziga nacyo kiri hejuru kuruta mbere, nuburyo bwo kugabanya no kugenzura ubushyuhe bwiki gice cya sisitemu kuva kurwego rwibikoresho kandi urwego rwa sisitemu niyo ngingo igomba kunozwa no gukemurwa na buri sosiyete mugihe kizaza; Byongeye kandi, iki gice cyubushyuhe ntabwo ari ubushyuhe buzanwa no kwishyurwa birenze urugero, ahubwo nubushyuhe buzanwa n’ibikoresho by’amashanyarazi menshi, bityo rero uburyo bwo gukora igenzura nyaryo kandi rihamye, rikora neza kandi ryizewe kugira ngo rikureho ubushyuhe ni ngombwa cyane, ntabwo ari intambwe igaragara mu bikoresho gusa, ahubwo ni no gutahura buri gihe, nko kugenzura igihe no kugenzura neza ubushyuhe bw’ubushyuhe.

Kuri ubu, ibisohoka voltage yaDC kwishyuza ibirundoku isoko muri rusange ni 400V, idashobora kwishyuza mu buryo butaziguye amashanyarazi ya 800V, bityo rero hakenewe kongera ingufu za DCDC kugirango hazamurwe ingufu za 400V kugeza kuri 800V, hanyuma hanyuma ushake bateri, bisaba ingufu nyinshi hamwe no guhinduranya imirongo myinshi, kandi module ikoresha karbide ya silicon kugirango isimbuze IGBT gakondo niyo ihitamo cyane, ariko na modulike ya Carbide irashobora no kongera imbaraga zo kwishyuza, kandi na moderi nyinshi zishobora kwishyurwa, hejuru.

Kubivuga muri make. Ahanini, kwiyongera kwa voltage bizakenera kongerwa kurwego rwa sisitemu no kurwego rwibikoresho, harimo sisitemu yo gucunga amashyuza, sisitemu yo gukingira umuriro, nibindi, kandi urwego rwibikoresho rurimo kunoza ibikoresho bimwe na bimwe bya magneti nibikoresho byamashanyarazi.
