Indima yee-capacitors zefilimu kunye namashishini asetyenziswayo aphambili

I-Film capacitor ikwabizwa ngokuba yi-plastic film capacitor.Isebenzisa ifilimu yeplastiki njengedielectric.Ibhekisela kwi-foil yensimbi njenge-electrode, kunye nefilimu yeplastiki efana ne-polyethylene, i-polypropylene, i-polystyrene okanye i-polycarbonate, iya kugqithwa ukusuka kwiziphelo zombini kunye nenxeba kwisakhiwo se-cylindrical.Kulo mhleli ulandelayo uya kukwazisa "indima kunye neendawo eziphambili zesicelo sefilimu capacitors".

Indima yefilimu capacitors

I-filimi capacitors isetyenziswa ngokubanzi kwi-high-frequency filtering, i-high-frequency bypassing, i-oda lokuqala okanye i-second-order filter circuits.

a.Ngokufana nazo zonke ezinye ii-capacitors, indima yefilimu i-capacitors kukujongana nesenzo somrhumo wombane.Njengenxalenye yetshiphu (ngokuqhelekileyo) ekwaziyo ukubamba imali encinci yentlawulo yombane.
b.Xa kuthelekiswa nezinye ii-capacitors ngokubanzi, ii-filimi capacitors zineempawu ezininzi ezibalaseleyo ezinomsebenzi ogqwesileyo.Iimpawu zayo eziphambili zimi ngolu hlobo lulandelayo: i-non-polarity, i-insulation resistance resistance, iimpawu ezibalaseleyo ze-frequency (i-broad frequency response), kunye nelahleko encinci ye-dielectric.
c.Phakathi kwabo, i-capacitor yolu hlobo lwefilimu enesinyithi inento ebizwa ngokuba yi-self-healing effect (Self Healing Action), oko kukuthi, ukuba inxalenye encinci ye-electrode ifutshane ngenxa ye-dielectric ebuthathaka, i-electrode metal ejikelezayo. inxalenye ye-short-circuit, echaphazelekayo ngamandla e-electrostatic okanye i-short-circuit current eqhutywe yi-capacitor ngelo xesha, iya kubangela indawo enkulu yokunyibilika kunye ne-evaporation ukubuyisela i-insulation, ukwenzela ukuba i-capacitor iya kubuyisela umsebenzi we-capacitor.Oko kukuthi, inokuziphilisa ngephanyazo.

Eyona appliamashishini eedyee-capacitors zefilimu

Iifilimi capacitors zisetyenziswa ikakhulu kwi-electronics, izixhobo zasekhaya, unxibelelwano, amandla ombane, oololiwe bombane, izithuthi ezixubeneyo, amandla omoya, amandla elanga kunye namanye amashishini.Uphuhliso oluzinzileyo lwala mashishini lukhuthaze ukukhula kwemarike yefilimu ye-capacitor.

Ngophuhliso lwetekhnoloji, umjikelo wokutshintshwa kwezinto zombane, izixhobo zombane zasekhaya, unxibelelwano kunye namanye amashishini uya usiba mfutshane kwaye ube mfutshane, kwaye ii-capacitors zefilimu, kunye nokusebenza kakuhle kombane kunye nokuthembeka okuphezulu, ziye zaba yinto eyimfuneko ye-elektroniki ukukhuthaza ukutshintshwa koku kungasentla. amashishini.Kule minyaka imbalwa izayo, ngophuhliso olongezelelweyo lwedijithali, ukwazisa kunye nokwakhiwa kothungelwano, kunye nokwanda kotyalo-mali lwelizwe kulwakhiwo lwegridi yombane, ukwakhiwa kombane kaloliwe, ukukhanyisa okonga umbane, izithuthi ezixutyiweyo, njl. njl., kunye nokuphuculwa kwabathengi. Iimveliso ze-elektroniki, imfuno yentengiso yee-capacitors zefilimu iya kuphinda ibonise umkhwa wokukhula okukhawulezayo.

amashishini asetyenzisiweyo3

1) Isetyenziswa kwiisekethe zombane zombane.Ii-capacitors zefilimu zisetyenziswa ikakhulu njenge-buffer kunye ne-clamping yamandla kunye ne-current, i-resonant bypass, kunye noxinzelelo lokuphazamiseka kwe-electromagnetic kubonelelo lwamandla.

I-2) Xa i-capacitor yefilimu isetyenziswa njengendlela yokudlula, inciphisa ubukhulu becala i-impedance yebhasi ye-DC kwaye ifunxa i-ripple current kumthwalo, ngaloo ndlela icinezela ngokufanelekileyo ukuguquguquka kwe-voltage yebhasi ye-DC okubangelwa utshintsho ngequbuliso lomthwalo.

3) Xa isixhobo sombane sisetyenziswa kwisiguquli se-resonant, umsebenzi we-resonance uya kufezekiswa ngokusebenza kunye ne-inductor.
