Muchinyorwa chakapfuura takatarisa pane imwe yenzira mbiri dzakasiyana dzekuzvirapa mune metalised film capacitors: discharge self-healing, inozivikanwawo seyepamusoro-voltage self-healing.Muchikamu chino tichatarisa kune rumwe rudzi rwekuzvirapa, electrochemical self-healing, inowanzonziwo pasi-voltage self-healing.

Electrochemical Self-Healing

Kuzvirapa kwakadaro kunowanzoitika mualuminium metalised film capacitors pa low voltage.Iyo nzira yekuzviporesa iyi ndeyotevera: kana paine kukanganisa mu dielectric firimu ye metalised film capacitor, mushure meiyo voltage yawedzerwa kune capacitor (kunyangwe kana voltage yakadzikira), pachava nekudonha kukuru. ikozvino kuburikidza nekuremara, iyo inoratidzirwa sekudzivirira kwekudzivirira kwe capacitor kwakaderera zvikuru kudarika kukosha kunotsanangurwa mumamiriro ehutano.Zviripachena, kune ionic mafungu uye pamwe magetsi emagetsi mune inodonha ikozvino.Nekuti marudzi ese emafirimu emusikirwo ane mwero wekunyura kwemvura (0.01% kusvika 0.4%) uye nekuti macapacitor anogona kunge ari pasi pehunyoro panguva yekugadzira, kuchengetedza uye kushandiswa, chikamu chakakosha cheiyo ionic ikozvino ichava O2- uye H-ion. mafambiro anokonzerwa nemvura ari electrolysed.Mushure mokunge O2-ion yasvika kune AL metalised anode, inosanganiswa ne AL kuti iite AL2O3, iyo zvishoma nezvishoma inoumba AL2O3 insulation layer nekufamba kwenguva kuvhara uye kuparadzanisa kukanganisa, nokudaro kuwedzera kudzivirira kwekudzivirira kwe capacitor uye kubudirira kuzvirapa.

Zviri pachena kuti humwe huwandu hwesimba hunodiwa kuti upedze kuzviporesa kwesimbi yakasvibiswa organic film capacitor.Kune miviri miviri yesimba, imwe inobva kumagetsi uye imwe inobva kune oxidation uye nitriding exothermic reaction yesimbi muchikamu chakasvibiswa, simba rinodiwa pakuzviporesa rinowanzonzi simba rekuzviporesa.

 
Kuzviporesa ndicho chinhu chinonyanya kukosha chemetalised film capacitors uye mabhenefiti ayo anounza makuru.Zvisinei, pane zvimwe zvipingamupinyi, zvakadai sekuderedzwa zvishoma nezvishoma mukukwanisa kwecapacitor inoshandiswa.Kana simba riri kushanda nehuwandu hwekuzviporesa, huchatungamirira kuderera kukuru kwehutano hwayo uye kushorwa kwekudzivirira, kuwedzera kukuru kwekurasikirwa kwekona uye kukurumidza kukundikana kwe capacitor.

Kana iwe uine nzwisiso mune mamwe maficha ekuzviporesa ega metalised film capacitors, ndapota kurukura navo nesu.
