Yini i-capacitor eguqukayo?

I-capacitor eguquguqukayo uhlobo lwe-capacitor inani lawo lama-capacitance lingalungiswa ngesandla noma nge-elekthronikhi.Ngokungafani nama-capacitors ahleliwe, ama-capacitor aguqukayo anikela ngokuguquguquka okuguquguqukayo, okwenza ukuthi kube yizakhi ezibalulekile kuzinhlelo zokusebenza ezifana namasekethe we-RF (Radio Frequency), amanethiwekhi afanayo.Lezi zingxenye zilusizo ikakhulukazi ezinhlelweni ezidinga ukuguquguquka okuqhubekayo noma okuzayo.

Ngabe i-capacitor eguquguqukayo isebenza kanjani?

Ngokuyisisekelo, i-capacitor eguqukayo isebenza ngokushintsha ukugqagqana noma ibanga phakathi kwamapuleti aqhumayo.Imvamisa, liqukethe amasethi amabili amapuleti ensimbi: eyodwa ehleliwe futhi eyodwa iyanyakaza.Ngokujikeleza amapuleti athutha, indawo egcwele enamapuleti ahleliwe iyaguqulwa, eshintsha amandla.

Le ndlela yokulungiswa ivumela i-linear v ariat ion ye-capacitance ngaphakathi kwebanga elithile, inika amandla ukumiswa okuqondile kwamapharamitha wesekethe.

Ngaphezu kokushintsha indawo egqamile, ukuguqula ibanga phakathi kwamapuleti nakho kunomthelela.Ukukhulisa ibanga kunciphisa amandla, ngenkathi kuncipha kwandisa amandla.Lesi sici sivumela ukuhlehlisa okuhle ukuhlangabezana nezidingo ezithile zesekethe.

Izinhlobo zama-capacitor aguqukayo

Ama-capacitor aguqukayo ahlukaniswa ngokusekelwe ezintweni ze-dielectric ezisetshenzisiwe.Lezi zinhlobo ezimbili eziphambili zingama-capacitors e-air dielectric kanye nama-capacitors aqinile dielectric.

Ama-capacitor aguquguqukayo womoya

Ama-capacitors endiza asebenzisa umoya njengezinto ezibonakalayo ze-dielectric.Ngenkathi zingaklanywa njengoba kulungiswe noma kuguquguqukayo, izinhlobo eziguqukayo zisetshenziswa kakhulu ngenxa yokulula kwazo.Ama-capacitors e-Fixed Air awathandwa kakhulu kusukela ezinye izindlela ezingcono zivame ukutholakala.

Imvamisa, ama-capacitors amoya enziwe ngamasethi amabili amapuleti ensimbi ayindilinga ahlukaniswe umoya.Isethi elilodwa limile, kanti elinye linamathiselwe emgodini wokujikeleza.Lapho amapuleti ancipha ngaphezulu, amandla aphezulu kakhulu;lapho bedlula kancane, iCapacitance ingaphansi kwayo.Indlela yokunciphisa igiya ivame ukusetshenziswa ukuthuthukisa ukunemba nokulawula ngesikhathi sokuhleleka.

Ama-capacitors amoya ngokuvamile anamanani aphansi ama-capcacitance, asukela ku-100 pf kuya ku-1 nf, futhi asebenze ngaphakathi kwamandla we-voltage we-10V kuya ku-1000V.Ngoba umoya unamandla kagesi aphansi aphansi aphansi, kukhona ubungozi bokuqhekeka kwangaphakathi, okungaholela ekwehlulekeni.Naphezu kwamakhono abo aphansi, la ma-capacitors adlala indima ebalulekile ekuqinisekiseni umsebenzi ofanele wezinhlelo eziningi ze-elekthronikhi ngenxa yokwakhiwa kwawo nokusebenza kwawo.

Ama-capacitor aqinile aguquguqukayo

Ama-capacitors aguqukayo aguqukayo aguqukayo asebenzisa izinto ezinjengamashidi we-mica noma amafilimu epulasitiki phakathi kwamapuleti wensimbi ahleliwe futhi athukayo.Lezi zingxenye zivame ukuvalelwa ezindlini zepulasitiki ezisobala.

Kunezinhlobo eziningana zesakhiwo ze-capacitors eqinile ye-dielectric capacitors:

I-Single-Seal

I-Double-seal (lapho i-rotor, i-stator, kanye nezingxenye ze-dielectric zizungeza kahle)

I-Quad-Seal enamabethi amane ama-rotors, izibalo, kanye nezendlalelo ze-dielectric

Kusetshenziswa izinto eziqinile njengoba i-dielectric yenza ukuthi la ma-capacitors azinze futhi aqinile aqhathaniswa nezinhlobo ezivamile.Zisetshenziswa kabanzi kumadivayisi ahlukahlukene kagesi nezinhlelo.Okuhlukile ngakunye kunezimpawu ezihlukile nemisebenzi, nokukhethwa kuya ngezidingo ezithile zohlelo lokusebenza.

Izicelo zama-capacitor aguqukayo

Isetshenziswe emishini yezokwelapha efana nesikena se-MRI ukukhiqiza amasimu aqinile kazibuthe

Kuhlanganiswe nemibuthano ye-OSCillator yokuzinza imvamisa yemvamisa nokuzinza

Kusetshenziswe kuma-RF Transmitters ukuthola amasekethe amahle nokuqhakambisa kwamandla kuma-antennas ukuze kusebenze kahle

Ama-capacitors aguquguqukayo afakiwe asetshenziswa kuma-radio Things ukulungisa imvamisa, ukuvumela abasebenzisi ukuthi bangene eziteshini ezahlukene

Kumklamo wokuhlunga, ama-capacitor aguqukayo anika amandla ukuguqulwa kwezimpawu zokuphendula imvamisa, ukusekela ukucushwa okudlula okuphansi, okuphezulu, noma kwe-band-pass

Ama-capacitor aguqukayo abalulekile kunoma yisiphi isekethe esidinga ukuvumelana okuguqukayo.Izinhlobo ezivame kakhulu yi-air dielectric ne-capacitors eqinile ye-dielectric.Ukukhetha phakathi kwabo kuya ngezidingo ezithile zohlelo lokusebenza-imvamisa, amavolumu, usayizi, kanye nezimo zemvelo.Onjiniyela bahlola lezi zinto ngokucophelela ukukhetha i-capacitor efaneleke kakhulu ngomsebenzi.

Uma unemibuzo, sicela ukhululeke ukuxhumana nathi.I-ARIAT Tech izophendula ngokushesha.

Imibuzo Ebuzwa Njalo [I-FAQ]

1: Ngabe i-capacitor eguquguqukayo isebenza kanjani?

I-capacitor eguquguqukayo iguqula amandla ayo ngokushintsha indawo esebenza ngempumelelo noma ibanga phakathi kwamapuleti alo lwangaphakathi.I-capacitor ejwayelekile yokuguqukela emishini ifaka amapuleti ahleliwe (izibalo) namapuleti ahanjiswa (ama-rotors).Ngokujikeleza i-rotor, ukugcwala ngezinguquko zomlomo, eziguqula amandla.
