Kutsemuka kweyakakwira voltage ceramic capacitors inogona kuverengerwa mumapoka matatu. Panguva yekushandiswa kwema capacitor aya, kuputsika kunogona kuitika, izvo zvinowanzovhiringidza nyanzvi dzakawanda. Aya ma capacitor akaedzwa voltage, dissipation factor, kuburitsa chikamu, uye insulation kuramba panguva yekutenga, uye vese vakapasa bvunzo. Nekudaro, mushure memwedzi mitanhatu kana gore rekushandiswa, mamwe mahigh voltage ceramic capacitor akawanikwa akatsemuka. Aya mafractures anokonzerwa ne capacitors ivo pachavo kana kunze kwezvakatipoteredza zvinhu?
Kazhinji, kuparuka kweyakakwira voltage ceramic capacitors inogona kuverengerwa kune inotevera zvinogoneka zvitatu:
Mukana wekutanga kuora kwekupisa. Kana ma capacitor akaiswa pasi pekukurumidza kana kurebesa yakakwirira-frequency uye yakakwirira-ikozvino mamiriro ekushanda, iyo ceramic capacitors inogona kugadzira kupisa. Kunyange zvazvo chiyero chekugadzira kupisa chiri kunonoka, kutonhora kunokwira nokukurumidza, zvichiita kuti kuparara kwemafuta pakupisa kukuru.
Chechipiri chinogona kuitika ndechekuti kuparara kwemakemikari. Pane mikaha pakati pemamorekuru emukati eceramic capacitors, uye kukanganisa kwakadai sekutsemuka uye voids kunogona kuitika panguva yekugadzira capacitor (njodzi dzinogona kuitika mukugadzirwa kwezvinhu zvakaderera). Nokufamba kwenguva, mamwe maitiro emakemikari anogona kubudisa magasi akadai seozone uye carbon dioxide. Kana magasi aya akaungana, anogona kukanganisa kunze encapsulation layer uye kugadzira mapundu, zvichikonzera kutsemuka.
Mukana wechitatu ndewe ion kuputsika. Yakakwira voltage ceramic capacitors inotsamira pane ayoni achishingairira kufamba pasi pesimba remunda wemagetsi. Apo ions inoiswa pasi pemunda wemagetsi wakareba, kufamba kwavo kunowedzera. Panyaya yekunyanyisa ikozvino, iyo insulation layer inogona kukuvadzwa, zvichiita kuti iparare.
Kazhinji, kukundikana uku kunoitika mushure memwedzi mitanhatu kana kunyange gore. Nekudaro, zvigadzirwa zvevagadziri vane hutsika husina kunaka zvinogona kutadza mushure memwedzi mitatu chete. Mune mamwe mazwi, hupenyu hweaya akakwira voltage ceramic capacitors inongova mwedzi mitatu kusvika kune rimwe gore! Naizvozvo, iyi mhando ye capacitor kazhinji haina kukodzera kumidziyo yakakosha senge smart grid uye akakwira-voltage jenareta. Smart grid vatengi vanowanzoda ma capacitor kuti agare kwemakore makumi maviri.
Kuwedzera hupenyu hwema capacitor, mazano anotevera anogona kutariswa:
1)Tsiva iyo dielectric zvinhu zve capacitors. Semuenzaniso, masekete akatanga kushandisa X5R, Y5T, Y5P, uye mamwe maCeramics eKirasi II anogona kutsiviwa neClass I ceramics seN4700. Zvisinei, N4700 ine dielectric diki diki, saka macapacitor akagadzirwa neN4700 achave nehukuru hwakakura hweiyo voltage uye capacitance. Makeramiki eKirasi I anowanzo kuve nekushomeka kwekushomeka kwakapetwa kakapetwa kagumi kupfuura Class II ceramics, ichipa simba rakasimba rekudzivirira.
2)Sarudza vagadziri vecapacitor vane zvirinani zvemukati welding maitiro. Izvi zvinosanganisira kupfava uye kusakwana kwemahwendefa eceramic, ukobvu hwesirivheri plating, kuzara kweceramic plate edges, mhando yekusongera kune inotungamira kana simbi zviteshi, uye mwero we epoxy coating encapsulation. Aya mashoko ane hukama nechimiro chemukati uye chimiro chemhando ye capacitors. Macapacitor ane chimiro chiri nani chitarisiko kazhinji ane zvirinani kugadzira mukati.
Shandisa ma capacitor maviri mukuenderana pane imwe capacitor. Izvi zvinobvumira magetsi ekutanga anotakurwa neamwechete capacitor kuti agovererwe pakati pemacapacitor maviri, achivandudza kusimba kwese kwema capacitor. Nekudaro, iyi nzira inowedzera mari uye inoda imwe nzvimbo yekuisa maviri capacitor.
3) Kune yakanyanya kukwira voltage capacitor, senge 50kV, 60kV, kana kunyange 100kV, iyo yechinyakare imwe ceramic ndiro yakasanganiswa chimiro inogona kutsiviwa nekaviri-layer ceramic plate series kana parallel chimiro. Izvi zvinoshandisa kaviri-layer ceramic capacitors kusimudzira voltage kushingirira kugona. Izvi zvinopa yakaringana yakakwira voltage margin, uye yakakura iyo voltage margin, iyo yakareba hupenyu hunofungidzirwa hwema capacitor. Parizvino, kambani yeHVC chete inogona kuzadzisa chimiro chemukati cheyakakwira voltage zvedongo capacitors uchishandisa kaviri-layer ceramic mahwendefa. Nekudaro, iyi nzira inodhura uye ine yakanyanya kuoma maitiro ekugadzira. Kuti uwane rumwe ruzivo, ndapota bvunza timu yekutengesa uye engineering yekambani yeHVC.
