Ma ka ʻatikala ma mua, ua nānā mākou i kekahi o nā ʻano hana ʻelua o ka ho'ōla ponoʻī ʻana i nā capacitors kiʻiʻoniʻoni metalised: hoʻokuʻu i ka hoʻōla pilikino, ʻike ʻia hoʻi he hoʻōla pilikino kiʻekiʻe.Ma kēia ʻatikala e nānā mākou i ke ʻano ʻē aʻe o ka ho'ōla ponoʻī, electrochemical self-healing, i kapa pinepine ʻia ʻo ka haʻahaʻa-voltage self-healing.

Electrochemical Self-Healing

ʻO ia hoʻōla ponoʻī e hana pinepine ʻia i nā capacitors kiʻi metalised alumini ma ka haʻahaʻa haʻahaʻa.ʻO ke ʻano o kēia ho'ōla ponoʻī penei: inā he kīnā i ka kiʻi dielectric o ka capacitor film metalised, ma hope o ka hoʻohui ʻia ʻana o ka volta i ka capacitor (ʻoiai inā he haʻahaʻa loa ka volta), e nui ka leakage. i kēia manawa ma o ka hemahema, i hōʻike ʻia e like me ke kūpaʻa insulation o ka capacitor ʻoi aku ka haʻahaʻa ma mua o ka waiwai i kuhikuhi ʻia i nā kūlana ʻenehana.ʻIke loa, aia nā au ionic a me nā au uila paha i ke au leakage.No ka mea, loaʻa i nā ʻano kiʻi ʻoniʻoni ʻoniʻoni kekahi ʻano hoʻoheheʻe wai (0.01% a 0.4%) a no ka mea hiki ke kau ʻia nā capacitor i ka makū i ka wā o kā lākou hana ʻana, mālama ʻana a hoʻohana ʻia, ʻo kahi hapa nui o ka manawa ionic he O2- a me H-ion. nā au i loaʻa mai ka wai e hoʻoheheʻe ʻia.Ma hope o ka O2-ion hiki aku i ka AL metalised anode, hui ia me ka AL e hana AL2O3, ka mea e lohi i ka AL2O3 papa insulation ma luna o ka manawa e uhi a hoʻokaʻawale i ka hemahema, pela e hoʻonui ai i ka insulation kū'ē o ka capacitor a me ka loaʻa 'ana iho-ho'ōla.

ʻIke ʻia e koi ʻia kahi nui o ka ikehu e hoʻopau i ka hoʻōla ponoʻī ʻana o kahi capacitor kiʻiʻoniʻoni organik metalised.ʻElua kumu o ka ikehu, hoʻokahi mai ka mana a ʻo kekahi mai ka oxidation a me ka nitriding exothermic reaction o ka metala i loko o ka ʻāpana kīnā, ʻo ka ikehu i koi ʻia no ka hoʻōla ponoʻī ʻana i kapa pinepine ʻia ʻo ia ka ikehu ho'ōla ponoʻī.

 
ʻO ka hoʻōla ponoʻī ka mea nui loa o nā capacitors kiʻiʻoniʻoni metalised a ʻo nā pōmaikaʻi e lawe mai ai he mea nui.Eia nō naʻe, aia kekahi mau hemahema, e like me ka hoʻohaʻahaʻa haʻahaʻa i ka hiki o ka capacitor i hoʻohana ʻia.Inā hana ka mana me ka nui o ka ho'ōla pono'ī, e alakaʻi ia i ka emi nui o kona hiki a me ke kū'ēʻana i ka insulation, kahi piʻi nui o ka pohō a me ka wikiwiki o ka capacitor.

Inā loaʻa iā ʻoe nā ʻike i nā ʻano ʻē aʻe o nā waiwai hoʻōla ponoʻī o nā capacitors kiʻi metalised, e ʻoluʻolu e kūkākūkā me mākou.
