Ama-capacitors ayingxenye ebaluleke kakhulu emikhiqizweni kagesi.Badlala izindima ezibalulekile ekuhlungelweni okubushelelezi, ukuqunjelwa kwamandla, ukudlula kwesiginali kanye nokuhlanganiswa kwe-AC kanye ne-DC kwimishini ye-elekthronikhi.Njengoba sinikezwe ukwahlukahlukana nobubanzi bokusetshenziswa kwama-capacitor, kudingeka siqonde imininingwane yokusebenza, izici ezijwayelekile, nezinzuzo, ukulinganiselwa kwama-capacitors ahlukahlukene kwizicelo ezithile.Amapharamitha amakhulu kanye nokusetshenziswa kwama-capacitors kuzochazwa ngemininingwane engezansi.
1. I-Capacitance (CR): Leli yinani le-capacitance elikhonjiswe kumkhiqizo we-capacitor.Ukukhohlisa okungokwemvelo kwe-capacitor ahlukile kwehlukile.Mica and ceramic dielectric capacitors generally have lower capacitances (approximately under 5000pF), while paper, plastic, and some ceramic dielectric capacitors have medium capacitances (approximately between 0.005uF and 1.0uF).Ama-capacitors we-electrolytic ajwayele ukuba nekhono elikhudlwana.Le yindlela yokuhlukaniswa kokuqala.
2. Uhla lokushisa lwesigaba: Leli ibanga lokushisa elikhona lapho i-capacitor ingasebenza khona ngokuqhubekayo, ngokuya ngemikhawulo yokushisa yesigaba sayo, njengokushisa kwesigaba esiphezulu, izinga lokushisa lesigaba esiphansi kanye nokushisa kwesigaba okulinganiselwe.Le pharamitha ibalulekile ekufanelekeni kwe-capacitor ezindaweni ezihlukile zokusebenza.
3. I-VOLTAGE ekalwe (i-UR): Kukhombisa i-DC ephakeme ye-DC noma i-AC Votage (Inani elisebenzayo noma inani eliphakeme le-Pulse Voltage) ukuthi iCapacitor ingakwazi ukuhambisa ngokuqhubekayo emazingeni okushisa athile.Qaphela isimo seCorona, ikakhulukazi ngaphansi kwamasimu aphezulu kagesi, angadala ukuwohloka kwe-capacitor noma ukulimala.
4. Ukulahleka kwe-tangent (i-TGδ): Kuchaza isilinganiso samandla okulahleka kanye namandla asebenzayo we-capacitor ngaphansi kwe-voltage ye-sinusoidal ngokuvama okucacisiwe.I-tangent encane yokulahleka ibonisa ukulahleka okuphansi kwi-capacitor, okuyinto ebalulekile yokusebenza metric yamadivayisi kagesi.
5. Izici zokushisa zama-capacitors: Imvamisa i-20 ° C isetshenziswa njengezinga lokushisa lesethenjwa ukuchaza ushintsho lwamaphesenti wokuguquguquka kwamakhono ahlobene namazinga angu-20 e.
6. Impilo Yesevisi: Impilo yenkonzo ye-capacitor izokwehla njengoba izinga lokushisa lenyuka, ngoba izinga lokushisa eliphakeme lizosheshisa ukuguga kanye nokuwohloka kwe-medium.
7. Ukumelana nokufakelwa
Ama-capacitors angahlukaniswa izigaba ezimbili: ama-capacitors ahleliwe kanye nama-capacitor aguqukayo.Ama-capacitors ahleliwe ahlukaniswe ngama-capacitors ama-mica, ama-capacitors we-ceramic, amaphepha ephepha / ama-capacitors wefilimu, njll. Ngokuya ngezinto ezahlukahlukene ze-dielectric.Ngezimo ezihlukile zohlelo kanye nezidingo, sidinga ukukhetha ngokucophelela uhlobo olufanele lwe-capacitor.
