Umuyoboro muremure wa DC uhuza firime ya capacitori yumuriro wamashanyarazi

Ibisobanuro bigufi:

1. Ipaki ya plastike, ifunze hamwe na epoxy fridend epoxy resin, umuringa uyobora, urugero rwihariye

2. Kurwanya voltage nyinshi, kwikiza ibyuma bya polypropilene

3. ESR yo hasi, ubushobozi bwo gukora ibintu byinshi

4. ESR yo hasi, gabanya neza voltage yinyuma

5. Ubushobozi bunini, imiterere yoroheje

Urukurikirane rwa DKMJ-AP

Ubushobozi bwa firime yamashanyarazi hamwe nubuhanga bugenzurwa no kwikiza ni kimwe mubisubizo bya elegitoroniki yingufu abashakashatsi ba EV na HEV bashobora kwishingikirizaho kugirango bahuze ubunini bukomeye, uburemere, imikorere, hamwe na zero-catastrophique-gutsindwa kwizerwa ryiri soko risaba.

Imbaraga za firime zishobora gutanga ibisubizo byizewe bya EV na HEV bigomba kuba byujuje ibipimo byihariye bijyanye nibikoresho bya firime, gutunganya, no gushushanya.

Ikiranga

Iterambere rirambye ryabaye igitekerezo gikomeye kandi kiboneka hose mugihe cya none.By'umwihariko, mu nganda zingufu, ibisubizo byingufu bisukuye, bisubirwamo bisimbuza uburyo gakondo bushingiye kumavuta.Hamwe na EV na HEV nisoko rizamuka, inverters zirasabwa kugira ubunini buto, ubwinshi bwingufu, umurongo mugari (WGB) hamwe na zeru-catastrophique-kunanirwa kugirango bisimbuze moteri gakondo yo gutwika imbere (ICE).Nkigisubizo, capacitori ya firime yicyuma nikintu gisabwa kugirango ejo hazaza na EV na HEV byuzuze ibisabwa.

Ubushobozi bwa firime ya capacitori muri CRE ifite uburyo bwo kwikiza, ubushobozi bwo gukumira kunanirwa gukabije mugihe habaye inenge yimbere.Filime ya dielectric muri capacitor yacu yashizwemo ibikoresho byuma byashyizwemo vacuum kandi bifite umubyimba wa nanometero icumi gusa.Iyo hari ingingo idakomeye cyangwa umwanda kuri dielectric, hazabaho gusenyuka.Ingufu zarekuwe no gusohora arc kumeneka zizaba zihagije kugirango umwuka wicyuma uzenguruke, utandukane inenge kandi ukize neza ubushobozi kugirango ukomeze imikorere.

Hamwe nubu buhanga bwo kwikiza, ibyuma bya firime byuma byuma bikoreshwa muburyo butandukanye bwo kwisoko kandi birashobora kuzuza ibisabwa bya elegitoroniki bigezweho harimo nibya inverter zikoreshwa muri EV na HEV.Bafite igihe kirekire cyo kubaho no kwizerwa bifatika hamwe no gutsindwa kwa zeru.Usibye ibyiza byaturutse muburyo bwo kwikiza, ubushobozi bwacu nabwo ni buto mubunini hamwe nubushobozi bunini.Birashobora gushyirwaho byoroshye kandi birashobora kurwanya voltage ndende.

Ububiko bwa firime yicyuma ikoreshwa nubushakashatsi bwa CRE.Mubisanzwe bashiramo ibishishwa byumye, bikomeretsa kaseti ya Myra kandi bigashyirwaho ikimenyetso cyicyuma cyangwa plastike.Igishushanyo cya patenti kizazana inyungu zinyuranye zirimo kuringaniza ibigezweho na inductance, nta kwaguka gukomeye kwumuriro, amashanyarazi menshi hamwe nigiciro gito cyumusaruro.Imashini nyinshi ya capacitor bobbin irashobora kugurishwa muburyo bwa bisi kugirango itange indangagaciro zo kwikebesha zishobora gukoreshwa kugirango ugabanye ingufu za voltage mugihe cyo guhinduranya.

Nka kimwe mubisubizo byingufu zingufu ziterambere niterambere rirambye, isoko rya EV na HEV biteganijwe ko rizakomeza kwaguka kandi amaherezo risimbuza ICE.Ububiko bwa firime ibyuma muri Wuxi CRE bizaba igisubizo cyiza, cyizewe kandi kiyobora kubikorwa byawe biri imbere.
