Ma capacitor a ceramic okwera kwambiri amakhala ndi mawonekedwe owoneka ngati chimbale, makamaka mumtundu wa buluu, ngakhale opanga ena amagwiritsa ntchito ma disc achikasu a ceramic. Mosiyana ndi izi, ma cylindrical high-voltage ceramic capacitors, okhala ndi bolt terminals pakatikati pa nyumbayo, amakhala ndi zigawo zosindikizira za epoxy zomwe zimasiyana mumitundu pakati pa opanga osiyanasiyana, monga buluu, wakuda, woyera, bulauni, kapena wofiira. Kusiyana kwakukulu pakati pa mitundu iwiriyi ndi motere:

 

1) Pankhani ya mphamvu yopangira pamsika, ma ceramic disc-mtundu wa high-voltage ceramic capacitors ali ndi mphamvu zopangira zambiri. Amagwiritsidwa ntchito pazinthu zosiyanasiyana, monga zida za electrostatic, ma ion negative, magetsi okwera kwambiri, ma frequency owirikiza kawiri, makina a CT/X-ray, ndi zina zomwe zimafunikira zida zamphamvu kwambiri. Cylindrical high-voltage ceramic capacitors ali ndi mphamvu zochepa zopangira ndipo amagwiritsidwa ntchito makamaka pazida zokhala ndi mphamvu zambiri, zamakono zamakono, kutsindika pa pulse impact, kutulutsa, ndi zina zotero. , magetsi othamanga kwambiri, zida zamphamvu kwambiri za CT ndi MRI, ndi ma lasers osiyanasiyana aboma ndi azachipatala monga zinthu zolipirira ndi zotulutsa.

 

2) Ngakhale ma cylindrical bolt terminal high-voltage ceramic capacitors amatha kugwiritsa ntchito zida zosiyanasiyana zadothi monga Y5T, Y5U, Y5P, zinthu zazikulu zomwe zimagwiritsidwa ntchito ndi N4700. Makasitomala amasankha ma bolt terminals chifukwa amaika patsogolo ma voliyumu apamwamba amtundu uwu wa capacitor. Mwachitsanzo, voteji yapamwamba ya ma capacitor amtundu wa lead ndi pafupifupi 60-70 kV, pomwe mphamvu yayikulu yama cylindrical bolt terminal capacitors imatha kupitilira 120 kV. Komabe, zinthu za N4700 zokha zimatha kupirira mulingo wapamwamba kwambiri wamagetsi mkati mwagawo lomwelo. Mitundu ina ya ceramic, ngakhale italephera kupanga ma capacitor, imakhala ndi moyo waufupi kwambiri wautumiki komanso moyo wa capacitor kuposa N4700, zomwe zitha kubweretsa zoopsa zobisika. (Dziwani: Kutalika kwa moyo wa ma capacitors a N4700 ndi zaka 20, ndi nthawi ya chitsimikizo cha zaka 10.)

 

Zinthu za N4700 zilinso ndi zabwino monga kutentha pang'ono, kukana kutsika, mawonekedwe abwino kwambiri, kutayika kochepa, komanso kutsika kwamkati mkati. Zina zamtundu wa blue high-voltage ceramic chip capacitor zimagwiritsanso ntchito zinthu za N4700 ndipo zimagwiritsidwa ntchito kwambiri pazida zotsika mphamvu komanso zotsika, monga makina a Philips/Siemens X-ray ndi makina ojambulira a CT. Mofananamo, moyo wawo wautumiki ukhoza kufika zaka 10 mpaka 20.

 

3） Makhalidwe apamwamba kwambiri komanso mphamvu zamakono za cylindrical high-voltage ceramic capacitors ndizoposa za disc-type ceramic capacitors. Mafupipafupi a ma cylindrical capacitor nthawi zambiri amakhala pakati pa 30 kHz ndi 150 kHz, ndipo mitundu ina imatha kupirira mafunde apompopompo mpaka 1000 A ndi mafunde osalekeza a makumi angapo a Ampere kapena kupitilira apo. Ceramic disc capacitors, monga omwe amagwiritsa ntchito zinthu za N4700, nthawi zambiri amagwiritsidwa ntchito pamtundu wapamwamba kwambiri wa 30 kHz mpaka 100 kHz, ndi mavoti apano omwe amachokera ku makumi mpaka mazana a milliampere.

 

4） Posankha ma capacitor okwera kwambiri, mainjiniya pafakitale sayenera kuganizira mtengo wokha komanso izi:

Ogulitsa a HVC nthawi zambiri amafunsa za zida zamakasitomala, ma frequency ogwiritsira ntchito, kutentha kozungulira, malo otsekera, mphamvu yamagetsi, ma overcurrent, komanso ngati pali zofunika pamitengo yotulutsa pang'ono. Makasitomala ena amafunikiranso kukana kochepa, kukula kochepa, kapena zina. Pokhapokha pomvetsetsa izi m'pamene ogulitsa a HVC angalimbikitse mwachangu ndikupereka zinthu zoyenera zokhala ndi ma capacitor apamwamba kwambiri.
