Gukoresha Imashini yo gusudira Hagati ya Frequency Frequency Imashini munganda nshya yimodoka: Imbaraga zimpinduramatwara ya tekinoroji yo gusudira neza

I. Ihame rya tekiniki nibyiza byingenzi byimashini yo gusudira Hagati yumwanya muto
Uwitekaimashini yo hagati yo gusudirani ibikoresho byo gusudira birwanya bishingiye ku buhanga bwa inverter. Ikintu cyibanze kiranga ni ugukoresha 1-4kHz yumurongo wa AC itanga amashanyarazi, hamwe no kugenzura neza gusudira amashanyarazi, igihe, nigitutu binyuze muri sisitemu yo kugenzura imibare. Ugereranije n’imashini gakondo yo gusudira AC (50 / 60Hz), imashini yo gusudira yumwanya wo hagati yerekana ibintu bitatu byingenzi bya tekiniki mubikorwa bya NEV:

• Byahinduwe neza Ubwiza bwo gusudira?

Hagati ya tekinoroji ya inverter ikora irashobora kugenzura imiterere yumurongo wa DC ihagaze neza, bikagabanya gusudira hamwe no guhindura ubushyuhe. Kurugero, muri aluminiyumu yumubiri wo gusudira, imashini yo gusudira yumwanya wo hagati irashobora kugera hejuru - gusudira neza hamwe nikosa rya diametre ya nugget iri munsi ya 0.2mm, ukirinda neza ibibazo bya batiri bipfunyika byatewe no gukomera gusudira bidahagije.

• Gukoresha ingufu Byashyizwe hejuru na 30%?

Bitewe nintege nke zuruhu rwumuvuduko ukabije, ibikoresho birashobora kugabanya gutakaza ingufu. Ibipimo nyabyo byo gupima byerekana ko iyo gusudira amabati y'ibyuma afite ubunini bumwe, gukoresha ingufu zimashini zo gusudira ziciriritse ziri munsi ya 35% ugereranije n’ibikoresho gakondo, bifite akamaro gakomeye ku bigo bya NEV kugabanya ibiciro no kongera imikorere.

• Guhuza imbaraga nimbaraga zubwenge?

Imashini zo gusudira ziciriritse ziciriritse zishyigikira guhuza hamwe na robo yinganda hamwe na sisitemu yo kugenzura iyerekwa. Dufashe nk'urugero rwa Tesla Gigafactory, aho rukorera rwo gusudira, binyuze mu bufatanye bw'imashini zo gusudira ziciriritse ziciriritse hamwe na robo esheshatu - axis, byagabanije igihe cyo gusudira cy’umubiri wera wa Model Y kugeza ku masegonda 45, byongera umusaruro ku bicuruzwa hafi 40%.

II. Urufunguzo rwo Gushyira mu bikorwa Urwego rwo hagati rwumwanya wo gusudira Imashini yo gusudira muri NEV Gukora
(I) Gukora amashanyarazi ya Batiri
Nka "umutima" wibinyabiziga bishya byingufu, ubwiza bwo gusudira kumashanyarazi ya batiri yumuriro bifitanye isano itaziguye numutekano wibinyabiziga. Uwitekaimashini yo hagati yo gusudiraigira uruhare runini mumirongo ikurikira:

• Gusudira Tab ya Cell?:Ukoresheje uburyo bubiri - pulse ikoreshwa rya tekinoroji yo gusudira, guhuza umuringa - ibikoresho bisa na aluminiyumu birangira mu masegonda 0.1, hamwe no kurwanya interineti bishobora kugenzurwa munsi ya 20μΩ.
• Module Busbar Welding?:Binyuze mu buryo bwo kurwanya imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y’imihindagurikire y'ikirere.
• Ikariso yo gufunga gusudira?:Gukoresha ubushyuhe buke bwinjiza biranga inshuro yo gusudira hagati, kwangirika hagati yimibiri ya aluminium alloy ibikoresho mugihe cyo gusudira biririndwa.

(II) Gukora umubiri woroshye
Kugirango wuzuze ibisabwa byoroheje byimodoka nshya zingufu ,.imashini yo hagati yo gusudirayakoze intambwe mu bice bikurikira:

• Aluminium - Guhuza Ibikoresho Bitandukanye?Binyuze mu ikoranabuhanga rikurikirana rirwanya imbaraga, ihuza ryizewe hagati ya 1.2mm ya aluminiyumu na 0.8mm z'uburebure - ibyuma byimbaraga bigerwaho, hamwe nimbaraga zifatika zigera kuri 85% byicyuma fatizo.
• Ashyushye - Kashe yo gusudira ibyuma?:Ku cyiciro cya 1500MPa gishyushye - kashe ya kashe, gahunda yo kugenzura icyiciro cya none irategurwa, ikarenga icyuho cya tekinike yo gusudira ahantu gakondo ikunda kubyara.

(III) Gutwara Sisitemu yo kugenzura moteri na elegitoroniki

• Muri stator yibanze yo gusudira ya moteri ihoraho ya moteri ihuza moteri ,.imashini yo hagati yo gusudiraikoresha tekinoroji yindishyi za electromagnetic kugirango igabanye igihombo cya magnetiki yo gusudira lamination kugeza munsi ya 0.3%. Mu gusudira k'umuringa gusudira kwa modul ya IGBT, milisegonda yayo - urwego rwo kugenzura impanuka zishobora kugabanya ubushyuhe - zone yibasiwe na 0.5mm, bikazamura cyane ubwizerwe bwa sisitemu yo kugenzura ikoranabuhanga.

III. Inzitizi za tekiniki hamwe niterambere ryigihe kizaza
(I) Inzitizi za tekiniki zubu

• Ibisabwa bitandukanye byo guhuza n'imihindagurikire y'ikirere?:Gukoresha ibikoresho bishya nka karuboni fibre yibigize hamwe na magnesium alloys ishyira hejuru ibisabwa kuri welding parameter optimiz.
• Umuvuduko wo kugenzura ibiciro?:Ibicuruzwa bitumizwa mu mahanga hejuru - amaherezo yo gusudira imashini yo gusudira ikomeza kuba hejuru ya 60%, kandi ibikoresho byo murugo bikenera byihutirwa intambwe yibice byingenzi.

(II) Icyerekezo cy'ikoranabuhanga kizaza

• Sisitemu yo gusudira yubwenge?:Kwinjizamo AI igenzura rya tekinoroji hamwe na tekinoroji ya tekinoroji kugirango ugere ku gihe - igihe cyo guhanura ubuziranenge bwo gusudira no gutunganya ubwacyo - gutezimbere.
• Ikoranabuhanga ryo gusudira ingufu?Gutezimbere inshuro ziciriritse - laser composite yo gusudira kugirango wongere umuvuduko wo gusudira kugera kumanota 120 / umunota.
• Iterambere ry'icyatsi kibisi?:Binyuze hejuru - inshuro zihindura uburyo bwo guhindura imikorere, kuzamura ibikoresho bikoresha ingufu zingana na 95%.

Umwanzuro
Mubikorwa bya NEV inganda zitera imbere zigana neza, ubwenge, nicyatsi ,.imashini yo hagati yo gusudira, nkibikoresho byingenzi bitunganyirizwa, ni uguhindura paradigima ya tekiniki yo gukora ibinyabiziga bigezweho. Hamwe nogukomeza gutera imbere mubice byingenzi nka sisitemu yo kugenzura servo hamwe na - impinduka zikoreshwa mu bikoresho byo mu rugo, biteganijwe ko mu 2025, ingano y’isoko ry’imashini zo gusudira ziciriritse zikoreshwa mu murima wa NEV zizarenga miliyari 8 CNY, zikaba moteri y’ikoranabuhanga mu kuzamura inganda. Ku nganda zikora ibinyabiziga hamwe nabatanga ibice, gusobanukirwa icyerekezo cyo guhanga udushya twikoranabuhanga ryo gusudira ruciriritse bizaba urufunguzo rwo gufata umwanya muremure mu cyiciro gishya cyamarushanwa yinganda.
