Muchinyorwa chapfuura takatarisa pane imwe yenzira mbiri dzakasiyana dzekuzviporesa muma capacitor efirimu ane metalised: kuzviporesa kwega, kunozivikanwawo sekuzviporesa kwega kwega kwemagetsi. Muchinyorwa chino tichatarisa rumwe rudzi rwekuzviporesa, kuzviporesa kwega kwemagetsi, kunowanzonziwo kuzviporesa kwega kwega kwemagetsi.

Kuzviporesa Kwemagetsi Nemakemikari

Kuzviporesa kwakadaro kunowanzoitika mumacapacitor efirimu ealuminium metalised pavoltage yakaderera. Maitiro ekuzviporesa uku ndeekuti: kana paine dambudziko mufirimu redielectric recapacitor yefirimu remetalised, mushure mekunge voltage yawedzerwa kucapacitor (kunyangwe voltage iri shoma kwazvo), pachava nekubuda kwemvura yakawanda kuburikidza nedefect, iyo inoratidzwa nekuti kudzivirira kwekudzivirira kwecapacitor kwakaderera zvakanyanya pane kukosha kwakatsanangurwa mumamiriro ehunyanzvi. Zviri pachena kuti kune ma ionic currents uye pamwe ma electronic currents mu leakage current. Nekuti marudzi ese ema organic films ane mwero wemvura (0.01% kusvika 0.4%) uye nekuti ma capacitors anogona kunge ari pasi pehunyoro panguva yekugadzirwa kwawo, kuchengetwa uye kushandiswa, chikamu chakakosha che ionic current chichava ma O2- ne H-ion currents anobva mumvura iri kushandiswa electrolys. Mushure mekunge O2-ion yasvika pa AL metalised anode, inosanganiswa ne AL kuti igadzire AL2O3, iyo inozopedzisira yaumba AL2O3 insulation layer nekufamba kwenguva kuti ivhare uye iparadzanise chikanganiso, nokudaro ichiwedzera kudzivirira insulation kwe capacitor uye ichizviporesa.

Zviri pachena kuti simba rakati wandei rinodiwa kuti chigadzirwa chesimbi che organic film capacitor chigadziriswe. Kune manyuko maviri esimba, rimwe rinobva mumagetsi uye rimwe rinobva mukuita kwe oxidation ne nitriding exothermic kwesimbi iri muchikamu che blem, simba rinodiwa pakuzviporesa rinowanzonzi simba rekuzviporesa.

 
Kuzviporesa ndicho chinhu chinonyanya kukosha pama capacitor esimbi uye mabhenefiti azvinounzira ndiwo makuru. Zvisinei, kune zvimwe zvakaipa, zvakaita sekuderera zvishoma nezvishoma kwesimba re capacitor inoshandiswa. Kana simba racho richishanda nekuzviporesa kwakawanda, zvichaita kuti simba raro ridzikire zvakanyanya uye kudzivirira kuvharika kwechinhu, kuwedzera kwakanyanya kwekona yekurasikirwa uye kukurumidza kutadza kushanda kwe capacitor.

Kana muine ruzivo nezvezvimwe zvinhu zvine chekuita nekuzvirapa kwemagetsi esimbi, ndapota taurai nesu nezvazvo.
