Kwinqaku elidlulileyo sigxininise kwenye yeendlela ezimbini ezahlukeneyo zokuziphilisa kwi-capacitors yefilimu ene-metalized: i-discharge self-healing, eyaziwa ngokuba yi-high-voltage self-healing.Kweli nqaku siza kujonga olunye uhlobo lokuziphilisa, i-electrochemical self-healing, ekwabizwa ngokuba yi-low-voltage self-healing.

Electrochemical Self-Healing

Ukuziphilisa okunjalo kuhlala kwenzeka kwi-aluminium metalized film capacitors kumbane ophantsi.Isixhobo sokuziphilisa simi ngolu hlobo lulandelayo: ukuba kukho isiphene kwifilimu ye-dielectric ye-capacitor yefilimu ene-metalized, emva kokuba i-voltage yongezwa kwi-capacitor (nokuba i-voltage iphantsi kakhulu), kuya kubakho ukuvuza okukhulu. okwangoku ngokusebenzisa i-defect, ebonakaliswa njengokumelana nokukhusela i-capacitor iphantsi kakhulu kunexabiso elichazwe kwiimeko zobugcisa.Ngokucacileyo, kukho imisinga ye-ionic kwaye mhlawumbi imisinga ye-elektroniki kumbane wokuvuza.Ngenxa yokuba zonke iintlobo zeefilimu eziphilayo zinezinga elithile lokufunxa kwamanzi (0.01% ukuya kwi-0.4%) kwaye ngenxa yokuba i-capacitors ingaba phantsi komswakama ngexesha lokwenziwa, ukugcinwa kunye nokusetyenziswa, inxalenye ebalulekileyo ye-ionic yangoku iya kuba yi-O2- kunye ne-H-ion. imisinga evela kumanzi okwenziwa ngombane.Emva kokuba i-O2-ion ifikelele kwi-AL metalised anode, idibanisa kunye ne-AL ukwenza i-AL2O3, eyenza ngokuthe ngcembe i-AL2O3 umaleko wokugquma ngokuhamba kwexesha ukugubungela kunye nokwahlula isiphene, ngaloo ndlela ukwandisa ukuxhathisa kwe-capacitor kunye nokuphumelela ukuziphilisa.

Kucacile ukuba umlinganiselo othile wamandla uyafuneka ukugqiba ukuziphilisa kwe-capacitor yefilimu ye-capacitor ye-metalized organic.Kukho imithombo emibini yamandla, enye isuka kunikezelo lwamandla kwaye enye isuka kwi-oxidation kunye ne-nitriding reaction exothermic yesinyithi kwicandelo lesiphako, amandla afunekayo ekuziphiliseni adla ngokubhekiswa njengamandla okuziphilisa.

 
Ukuziphilisa yeyona nto ibalulekileyo ye-metalized film capacitors kunye neenzuzo ezizisayo zinkulu.Nangona kunjalo, kukho ukungonakali, njengokuncitshiswa ngokuthe ngcembe kumthamo we-capacitor esetyenziswayo.Ukuba amandla asebenza ngobuninzi bokuziphilisa, kuya kukhokelela ekunciphiseni okukhulu kwamandla kunye nokuchasana kwe-insulation, ukunyuka okukhulu kwi-angle yokulahlekelwa kunye nokungaphumeleli ngokukhawuleza kwe-capacitor.

Ukuba unombono weminye imiba yeempawu zokuziphilisa ze-metalized film capacitors, nceda uxoxe ngazo nathi.
