Ibikoresho byabigenewe byifashishwa mumashanyarazi ya DC
Ibisobanuro
Imikorere iranga ubushobozi bwa firime iratandukanye cyane bitewe nibikoresho bya dielectric bikoreshwa kimwe nubuhanga bwubwubatsi bukoreshwa.Bimwe mubikoreshwa cyane muri firime ya dielectrics ya plastike harimo polyethylene naphthalate (PEN), polyethylene terephthalate (PET), na polypropilene (PP).
Ububiko bwa firime ya plastike irashobora gushyirwa mubice muri firime / file hamwe na capacitori ya firime.Imiterere yibanze ya firime / foil capacitor igizwe nibyuma bibiri bya electrode yicyuma na dielectric ya plastike hagati yabo.Ubushobozi bwa firime / foil butanga imbaraga zo kurwanya insulasiyo nyinshi, ubushobozi bwo gufata impiswi nyinshi, ubushobozi bwiza bwo gutwara ibintu, hamwe nubushobozi buhamye.Bitandukanye na capacitori ya firime / fayili, ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bya pulasitiki bisize ibyuma nka electrode.Ububiko bwa firime metallised bwagabanije ingano yumubiri, kandi butanga imbaraga zingana cyane, ubushobozi bwiza butajegajega, igihombo gito cya dielectric, nibintu byiza byo kwikiza.Ubushobozi bumwe ni imvange ya firime / foil capacator hamwe na capacitori ya firime hamwe nibiranga ubwoko bwombi.Imiterere-yo kwikiza yimikorere ya firime ya metallize ituma iba nziza kumurongo mugari wa porogaramu, harimo kuramba hamwe nuburyo bwiza bwo gutsindwa.
Kwikiza kwicyuma cya firime
Dielectrics ya plastike isanzwe ikoreshwa mukubaka ibyuma bifata ibyuma birimo polypropilene (PP), polifenile sulfide (PPS), polyester, nimpapuro zicyuma (MP).Ibi bikoresho bya dielectric bifite ubushobozi butandukanye bwo kwikiza.
Iyo gusenyuka bibaye muma capacitori ya firime, arcing itera icyuma cyoroshye cyane kizengurutse agace kavamo umwuka.Ubu buryo bwo guhumeka bukuraho icyuma kiyobora mugice gikikije inenge.Kubera ko ibikoresho bitwara byavanyweho, umuzenguruko muto ntushobora kubaho hagati yamasahani.Ibi birinda kunanirwa kwibigize.
Ubushobozi bwo kwikiza bwa capacitori ya firime metallised biterwa nibintu byinshi birimo imiterere yibikoresho bya dielectric hamwe nubunini bwicyuma.Imyuka ihumeka isaba gutanga ogisijene ihagije hamwe nibikoresho bya dielectric bifite ogisijeni yo hejuru ifite ibintu byiza byo kwikiza.Bimwe mubya firime ya plastike dielectrics ifite ibyiza byo kwikiza harimo polypropilene, polyester na polyakarubone.Ku rundi ruhande, dielectrics ya firime ya plastike irimo ogisijeni nkeya ifite imiterere mibi yo kwikiza.Polyphenylene sulfide (PPS) ni kimwe mu bikoresho bya dielectric.
Usibye kongera ubwizerwe, ubushobozi bwo kwikiza bwa capacitori ya firime ifasha kuzamura ubuzima bwabo bwimikorere.Nyamara, kwikiza bitera kugabanuka kwicyuma cya electrode yumwanya mugihe.
Mubisabwa, bimwe mubintu bishobora kwihutisha kunanirwa kwikintu harimo ubushyuhe bwinshi, voltage nyinshi, inkuba, ubuhehere bwinshi, hamwe nimbogamizi ya electronique (EMI).
Usibye ibintu byiza byo kwikiza, ibyuma bya polyester byuma byuma bifite na dielectric ihoraho, ihindagurika ryubushyuhe bwiza, imbaraga za dielectric, hamwe nubushobozi buhebuje.Ibiranga bituma capacator ziba nziza kubikorwa rusange.Imiyoboro ya polyester ikoreshwa cyane mugukoresha DC nko guhagarika, kurenga, gukuramo, no guhagarika urusaku.
Imashanyarazi ya polypropilene itanga ibyuma birwanya ubukana bwinshi, kwinjiza dielectric nkeya, igihombo gito cya dielectric, imbaraga za dielectric, hamwe nigihe kirekire.Ibice bikora neza bikoreshwa cyane muburyo bukoreshwa cyane nka filteri yumuzunguruko, kumurika ballast, hamwe na snubber.Ububiko bwa firime bubiri bwa polypropilene bushobora kwihanganira imbaraga nyinshi hamwe nimizigo myinshi, kandi birakwiriye gukoreshwa hamwe nibishoboka byinshi byimpanuka.Izi capacator zikoreshwa cyane mugucunga moteri, snubbers, guhinduranya uburyo bwo gutanga amashanyarazi, hamwe na monitor.
Umwanzuro
Ubwizerwe nubuzima bwimikorere ya capacator biterwa cyane nimiterere yabo yo kwikiza.Ibice bya pasiporo bifite ibyiza byo kwikiza birizewe kandi bitanga ubuzima burebure.Ibyiza byo kwikiza biranga ubushobozi bwa firime metasitori byongera imbaraga kandi bikabikoresha mubikorwa byinshi.Mubyongeyeho, ibyo bice bikomeye birananirana gufungura, kandi ibi bituma biba byiza kubisabwa bisaba ibice hamwe nuburyo bwo gutsindwa neza.
Kuruhande rwa flip, imitungo yo kwikiza ya capasitori ya firime itera ibintu bitera igihombo kwiyongera hamwe nubushobozi bwose bugabanuka.Usibye ibintu byiza byo kwikiza, ibyuma bya firime byinshi byuma bitanga imbaraga zo gusenyuka no gukora neza cyane.
Kubindi bisobanuro bya capacitori, nyamuneka kura kataloge ya CRE.
