Chisindikizo chakunja chosindikizira cha ma high voltage ceramic capacitors, makamaka epoxy layer, sichimangokhala ngati chotchinga komanso chimakhudza kwambiri mawonekedwe onse a capacitor yokha.

 

Choyamba, kugwirizana pakati pa tchipisi ta ceramic ndi epoxy layer ndi gawo lofunikira kwambiri. Kugwirizana kofooka kungayambitse kutsika kwa luso. Choncho, kachulukidwe ka malo omangirirawa amakhudza mwachindunji kukhulupirika kwa epoxy layer, ndipo kulumikizana kolimba kumapangitsa kuti pakhale zotulutsa zochepa.

 

Kachiwiri, panthawi yogwiritsira ntchito ma capacitor a ceramic pansi pa voteji yapamwamba kapena kutulutsa mpweya, kupsinjika kwa kutentha kumachitika. Kupsyinjika kobwerezabwereza kumeneku kumayambitsa kufalikira ndi kusagwirizana pakati pa zigawo zikuluzikulu, zomwe zimapangitsa kuti resin delamination. Kuchuluka kwa mpweya wa mpweya mkati mwa capacitor kumachepa kwambiri, pamene kupsinjika kwa epoxy wosanjikiza kumawonjezeka kwambiri, kumapangitsa kuti capacitor ikhale yovuta.

 

Kuphatikiza apo, zimavomerezedwa kuti pambuyo pa sintering pa kutentha kwakukulu, ma capacitors amafuna nthawi yobwezeretsa kuti achepetse kupsinjika kwa kutentha kudzera munjira zachilengedwe. Kutalika kwa nthawi yochira, kumapangitsa kuti ma capacitor athe kupirira kupsinjika, kuonetsetsa kuti ali apamwamba kwambiri. Mwachitsanzo, kuyerekeza ma capacitor omwe angopangidwa kumene ndi omwe adachira pafupifupi miyezi iwiri, omalizawa akuwonetsa kulekerera kwamphamvu kwambiri kwamagetsi, kukwaniritsa milingo ya 80kV kapena kupitilira apo atayesedwa pa 60kV poyambirira.

 

Kuphatikiza apo, kusankha kwa zida za epoxy kumatha kukhudza magwiridwe antchito a ma capacitor pa kutentha kosiyanasiyana. Ma capacitor ena a ceramic okwera kwambiri amatha kukhala ndi mphamvu zochepa pakutentha kotsika. Mwachitsanzo, ngati kuzizira kozizira kwambiri mpaka -30 digiri Celsius, ming'alu imatha kupangika chifukwa cha kuchepa kwa epoxy pamalo otsika otere kapena kusagwirizana ndi kukulitsa ndi kutsika kwa tchipisi ta ceramic. Chifukwa chake, kupsinjika kosagwirizana komwe kumabwera chifukwa cha kuzizira kwambiri kumalephera kuchepetsa voliyumu pamlingo womwewo, zomwe zimapangitsa kupsinjika kwamapangidwe.

 

Pothana ndi zinthu izi ndikuwonetsetsa kuti mawonekedwe a epoxy layer, opanga amatha kukonza magwiridwe antchito komanso kudalirika kwa ma capacitor apamwamba kwambiri.
