Uko imodoka nshya zikoresha ingufu ziyongera iterambere ryazo rigana ku gusharija vuba cyane, gusharija no gusohora umuriro mu cyerekezo kibiri, no guhuza neza, ikoranabuhanga rya OBC riri muri iyo ndege riravugururwa - sisitemu y'amashanyarazi ya 800V iragenda igana kuri sisitemu ya 1200V, kandi imiterere ya platforme ifite ingufu nyinshi iba ishingiro ryo gusharija vuba.
01 Ni uruhe ruhare rw'ingenzi capacitor igira muri OBC iri mu bwato?
Muri sisitemu ya bateri ifite voltage nyinshi, capacitor ni "ahantu ho kubika no kuyungurura ingufu" bya OBC & DCDC, kandi imikorere yayo igena mu buryo butaziguye imikorere, ubucucike bw'imbaraga n'ubwizigirwa bwa sisitemu - byaba ingaruka z'ako kanya z'urubuga rwa voltage nyinshi, ihindagurika ry'imbaraga zikoresha frequency nyinshi, cyangwa imiterere y'imikorere y'ingufu zikoreshwa mu cyerekezo cy'imirongo ibiri, capacitor irasabwa kugira ngo ikomeze gukora neza mu bidukikije bifite voltage nyinshi, frequency nyinshi, n'ubushyuhe bwinshi. Kubwibyo, guhitamo capacitors zirwanya voltage nyinshi n'ubucucike bwinshi ni ikintu cy'ingenzi mu kugena imikorere ya OBC iri mu bwato.
02 Ni izihe nyungu zo gukoresha capacitors za YMIN?
Mu rwego rwo guhangana n’ibisabwa bikomeye bya OBC & DCDC hifashishijwe sisitemu zifite ingufu nyinshi kugira ngo capacitors zishobore kwihanganira ingufu nyinshi, ingano nto, igihe kirekire, n’umuyoboro w’amashanyarazi mwinshi, YMIN yatangije matrix y’ibicuruzwa bya capacitor bifite imikorere myiza kugira ngo yongere imbaraga sisitemu ya OBC & DCDC y’imodoka nshya zikoresha ingufu.
01Capacitor ya electrolytic ya aluminiyumu yo mu bwoko bwa liquid horn: "umurinzi uhamye w'amashanyarazi" ku bintu bifite imbaraga nyinshi
· Umuvuduko mwinshi uhangana n'amashanyarazi: Mu rwego rwo guhangana n'ibibazo by'ihindagurika ry'amashanyarazi n'izamuka ry'amashanyarazi rikunze kugaragara muri OBC, capacitor ya CW3H series horn ifite imiterere ihagije ya voltage kugira ngo itange ubufasha bukomeye bwa voltage no kurinda overvoltage. Ikorerwa ibizamini bikomeye byo gusaza high voltage no kuramba kwayo mbere yo kuva mu ruganda kugira ngo irebe ko ihamye kandi yizewe cyane mu bikorwa bya OBC.
· Ubudahangarwa bw'umuyoboro w'amazi ukabije: Iyo OBC ikora, umuyoboro w'amazi uterwa no guhinduka k'imbaraga kenshi. Iyo capacitor ya aluminiyumu electrolytic capacitor y'amazi ikoreshejwe inshuro 1.3 z'umuyoboro w'amazi ukabije, ubushyuhe bukomeza kwiyongera kandi imikorere y'umusaruro irahamye.
· Ubucucike bw'ubushobozi bwinshi: Uburyo bwihariye bwo kuzunguruka butuma ingufu ziyongera neza. Ubushobozi buri hejuru ya 20% ugereranije n'inganda ku bunini bumwe. Kubera ingufu n'ubushobozi bimwe, ikigo cyacu ni gito mu bunini, bigatuma umwanya wo gushyiramo ugabanuka kandi kigahura n'uburyo mashini yose ikoresha.
02Capacitor ya electrolytic ya aluminiyumu ikoreshwa mu mazi: "Gukoresha neza" mu bushyuhe bwinshi n'ahantu hato
Uruhererekane rwa LKD rukoresha amashanyarazi aruminiyumu rushobora gukoreshwa mu buryo budashobora gukoresha amashanyarazi akoresha amashanyarazi bitewe n'ingano y'amazi. Ni amahitamo meza ku bijyanye no kuyungurura neza no kubika ingufu byizewe bya OBC ishyirwa mu modoka ahantu hafite amashanyarazi menshi, amashanyarazi menshi kandi hakomeye.
· Ubudahangarwa bw'ubushyuhe bwinshi: Kugera ku bushyuhe bwo gukora bwa 105℃ mu gipfunyika gito, birenga cyane capacitors rusange hamwe n'ubudahangarwa bw'ubushyuhe bwa 85℃, bitanga uburinzi bwizewe ku bidukikije bikoresha ubushyuhe bwinshi.
· Ubucucike bwinshi bw'ubushobozi: Munsi y'amashanyarazi amwe, ubushobozi bumwe n'ibipimo bimwe, umurambararo n'uburebure by'uruhererekane rwa LKD bito kuri 20% ugereranyije n'ibicuruzwa by'ihembe, kandi uburebure bushobora kuba bukeho 40%.
· Imikorere myiza y'amashanyarazi no gufunga: Kubera imiterere yayo yo kurwanya ubushyuhe bwinshi, ESR iragabanuka cyane, kandi ifite ubushobozi bukomeye bwo kurwanya umuvuduko w'amashanyarazi. Ibikoresho n'ikoranabuhanga bidasanzwe byo gufunga bituma umwuka wa LKD uruta capacitor y'ihoni, mu gihe byongera igihe cyo gukora, gishobora kugera ku masaha 105℃ 12000.
03 Capacitor y'amazi akomeye: "ikiraro cy'inzira ebyiri" kiri hagati y'imikorere myiza n'ituze
· Ubucucike bwinshi bw'ubushobozi: Ugereranyije na capacitors zifite ubunini bumwe ku isoko, ubushobozi bwaCapacitors za YMIN solid-liquid hybridyongereweho ibirenze 30%, kandi agaciro k'ubushobozi gahoraho kari hagati ya ± 5% mu bushyuhe bwinshi. Nyuma y'igihe kirekire, agaciro k'ubushobozi gahoraho kari hejuru ya 90%.
· Umuyoboro w'amazi uva hasi cyane na ESR nke: Umuyoboro w'amazi uva ushobora kugenzurwa muri 20μA, naho ESR ishobora kugenzurwa muri 8mΩ, kandi imiterere y'ibyo byombi ni myiza. Ndetse na nyuma yo gukoresha ubushyuhe bwinshi bwo kongera gusora kuri 260℃, ESR n'umuyoboro w'amazi bigumaho neza.
04 Capacitors za filime: "imbogamizi y'umutekano" ihoraho kandi yizewe cyane
Ugereranyije na capacitors za electrolytic, ibyiza by'imikorere ya capacitors za filime bigaragarira mu muvuduko mwinshi wo kwihanganira amashanyarazi, ESR nkeya, kudahindagurika, imikorere ihamye, no kuramba igihe kirekire, ibyo bigatuma imiterere ya sisitemu yayo yoroha, irwanya amajwi menshi, kandi ikaba yizewe cyane mu bidukikije bikomeye.
· Voltage yo kwihanganira amashanyarazi menshi cyane: ubushobozi bwo kwihanganira amashanyarazi menshi arenga 1200V, nta mpamvu yo guhuza amashanyarazi mu buryo butandukanye, kandi ishobora kwihanganira amashanyarazi akoreshwa inshuro 1.5.
· Ubushobozi bwo gukubita cyane: Ubushobozi bwo kwihanganira gukubita bwa 3μF/A buruta inshuro zirenga 50 ugereranyije n'ubushobozi bwa capacitors gakondo za electrolytic.
· Ingwate y'ubuzima bwose: amasaha arenga 100.000 yo gukora, ubwoko bw'umukungugu n'igihe ntarengwa cyo kumara. Mu gihe kimwe cyo gukoresha,capacitors za filimebashobora gukomeza imikorere yabo igihe kirekire.
Mu gihe kiri imbere, YMIN izakomeza gushakisha cyane ikoranabuhanga rya capacitor rifite ingufu nyinshi kandi rihujwe kugira ngo ritange ingufu zinoze kandi zizewe kuri sisitemu za OBC na DCDC z'imodoka nshya zikoresha ingufu!
