Mhando capacitors: uye zvaasingagoni

A capacitor ndiyo wemagetsi runovabvumira yokuchengetera uye ipapo kukumikidza zvemagetsi buditsa. The chikuru tive chinhu chiri pakukwanisa kwayo, kusarudza basa voltage kuyanzva.

kupatsanura pakati condensers

Various mano kusunungura ruzivo kubvumira kuti pave siyana namano. By mhepo condensers zvinosanganisira nyaya umo dielectric iri mhepo. Zvakanakira ichi mhando mano ndivo kudekara gadzira. Ivo zvakagadzirirwa zvokuimba kudzora kugona uye vakasikwa kuti kuramba zvokuimba zvazvinoita. Zvazvakashatira kwakadai mudziyo zvinosanganisira kusagadzikana, murombo kuvimbika, asi kuvimba mwando kudziya svikiro, hombe kukura, huri pasi simba dielectric iro rine parinoperera mhepo Kuparara pakati sinkers uye vakaderera capacitance.

Kune bepa mhando capacitors, iyo anoita somunhu dielectric mafuta transformer akaiswa mushonga wokuuraya mapepa. mano aya vane simba mukuru dielectric uye rakavimbika. Kana refu voltage , vane yakakwirira capacitance uye vakaderera leakage ano.

capacitors zhinji anobudiswa papepa hwaro simba zvinomera. Kuti aite izvi, peta pamwe mahwendefa maviri, pakati iyo pepa. The mudziyo ari ipapo anokungurutsirwa munzvimbo bwendefa uye akaisa mudende, iyo izere mafuta transformer uye ipapo chisimbiso. Zvazvakashatira mudziyo zvinosanganisira yakawanda uremu, mukuru kuzvidzora inductance uye nemishonga.

Electrolytic capacitors vane mhando dielectric, vakaisawo muchimiro ane oxide rukoko aumba pasi pemvura yezviri simbi (kazhinji aruminiyamu). The mudziyo zvinoberekwa achiisa ane electrolyte chakagadzirwa chinoshingaira simbi tepi, pose apo imwe firimu achiumbwa kubva rakasimba oxide, vachibvumira agopfigira simbi.

The chikuru chepfungwa electrolytic capacitors ndiyo kuvapo mhando polarity, mumwe ukoshi kuti abate yavose sezvavakatarirwa voltage, uye kana kuchinja nokukurumidza kuparadzwa. Izvi imhaka kwemakemikari pezvakaitwa kuitika pakati electrolyte uye simbi ndiro. Oxide firimu zvishoma makatsemuka uye hwatsvuka.

Zvisinei, muna zvaidiwa zvakarurama polarity microcracks nokukurumidza akasungirirwa oxide itsva. Zvakanakira mano izvi zvinosanganisira refu kukwanisa, zvikanganiso - polarity, kurasikirwa pfuma, kukurumidza vapfeke, yakakwirira zvemukati inductance.

Mhando capacitors vavo mafomu

Panewo mano iyo inoshanda sezvo dielectric naMika, vari kushandiswa mune zvivako siyana. Sezvo Mica oga anokwanisa kuchengeta simba, mhando iyi capacitors vane yakakwirira capacitance uye simba dielectric. Zvazvakaipira anosanganisira parameters kuti kusagadzikana, nonlinearity, mutengo mukuru uye kutsamira yacho capacitance ano.

Uyezve unoshandiswa pamusoro zvedongo mhando capacitors, firimu, teflon, polypropylene nezvimwe namano.
