Filimu capacitor - tanthauzo ndi gulu Share

The  filimu capacitor ndi capacitor ntchito filimu pulasitiki monga dielectric, amene ali kungokhala pakompyuta chigawo chimodzi kuti amasunga ndi kutulutsa mphamvu magetsi mu mawonekedwe electrostatic, amene akhoza kugawidwa mu bala, lamination, malungo ndipo palibe chitsanzo malinga ndi mawonekedwe a dongosolo, mmene voliyumu Yonse ntchito mozungulira zachilendo mtundu

 

Capacitor ndi insulating sing'anga mu insulating sing'anga pakati pa pole zitsulo conductive zinthu ndi masitolo ndi kutulutsa mphamvu magetsi mu mawonekedwe electrostatic, ndipo amatha kugwira ntchito, tun, fyuluta, coupling, kukonzanso, kulekanitsa DC voteji mu dera lamagetsi. Bypass, coupling, etc., yomwe imagwiritsidwa ntchito kwambiri mumitundu yosiyanasiyana ya ma frequency high and low frequency capacitor, ndi gawo lofunikira lamagetsi pamizere yamagetsi. Filimu yopyapyala ya filimuyi ndi capacitor yogwiritsira ntchito filimu ya pulasitiki ngati sing'anga.

 

The filimu capacitor ali ndi mtundu cholinga kukhala bala pa elekitirodi m'kati, mtundu sanali inductive amamangiriridwa ku mapeto pamwamba ogwiritsa waya kapena osachiritsika elekitirodi. Inductance ndi yaying'ono komanso mawonekedwe apamwamba kwambiri ndi ochepa poyerekeza ndi inductance. Panthawi imodzimodziyo, kutsekemera kochititsa chidwi kungathe kuchepetsa kutaya kwa filimu ya filimu ndikuwonjezera moyo wa capacitor. The laminated woonda film capacitor ndi yaying'ono kuposa chilonda makulidwe ndi voliyumu ndi oyenera mankhwala ang'onoang'ono zamagetsi. Mtundu wokhotakhota ndi woyenera kwambiri pamayendedwe apakatikati ndi ma pulse, motero mtundu wokhotakhota umagwiritsidwa ntchito kwambiri pakusefa, ziphuphu, zodutsa, kulumikizana, komanso kuchepetsa phokoso la zida zamagetsi zamagetsi.

 

Kafotokozedwe ka mawu

Decoupling capacitor: Mu dera lamagetsi, magetsi okhazikika amatha kuperekedwa, ndipo chinthu chochepetsera chimaphatikizidwa ndi phokoso la mapeto a magetsi, kusefa gulu la zigawo zomwe zimasokoneza kusokoneza kwa chizindikiro.

Zosefera: Wavy wodzigudubuza wa sawtooth atakonzedwanso, pafupi ndi DC.

Kuphatikizika: Monga kulumikizana pakati pa mabwalo awiriwa, chizindikiro cha AC chimaloledwa kudutsa ndikutumiza kudera lotsatira.

Bypass Capacitor: Mphamvu yomwe imasefedwa ndikudutsa magawo apamwamba kwambiri mu AC yapano yaposachedwa komanso yotsika kwambiri.

Chojambula cha Chemical: Pamwamba pake amakulitsidwa pambuyo pa electrochemistry kapena corrosion ya mankhwala ndi electrochemical kapena chemical etching, kenako electrochemically amapangidwa kukhala pamwamba pa filimu ya okusayidi (aluminium dioxide).

Kumangirira: Kumatanthauza kachitidwe kamene kamalowa m’maphukusi osiyanasiyana malingana ndi nthawi zina.

PET: Polyethylene terephthalate ndi utomoni wamba m'moyo.

PEN: Ethylene glycol ester wa polymethyl naphthalate ndi polima wabwino kwambiri yemwe akutuluka, ndipo mawonekedwe ake amafanana ndi PET.

PP: Polypropylene, ndi polima wopangidwa ndi kuwonjezera polymerization.

PPS: utomoni watsopano wochita bwino kwambiri wa thermoplastic.

 

Filimu capacitor ikhoza kugawidwa mumtundu wokhotakhota, mtundu wa lamination, inductive type ndi non inductance.
