Nemishonga yacho capacitor

A capacitor chimwe chezvinhu zvakafanana zvinhu zvemagetsi nematunhu. Mhando capacitors, vamwe parameters, dzakadai kurwisa ari capacitor, munyaya ino.

Tinogona kutaura kuti vaviri simbi electrodes dzakaparadzaniswa marongera mhepo, uye ane capacitor. Mumwe kwamahwendefa rine goho rayo uye kunogona chokuita ive remudunhu magetsi. mudziyo kwakadaro vane unhu, uye mumwe wavo ndiye kurwisa yacho capacitor.

Capacitor kana sezvazvakanyorwa kunzi, kukwanisa kuva anonakidza zvikuru zano. Zvakakwana kutaura kuti hapana zvakaitika DC. Kana kutarira DC semaonero iyi maonero, ari kurwisa iri capacitor riri guru kwazvo, anenge magumo DC.

Panguva iyoyowo, wokutanga nguva apo unobva mugaba kuti DC redunhu Kuyerera kwayo mutariri. Inside kunzwisisa kwemasayendisiti kutora nzvimbo. Kana capacitance akapiwa, ano chokubuda rakapotsa hunoguma. Asi pane imwe caveat, nokuda dielectric yepamusoro. Pasinei wakanaka insulator angava, achiri runoyerera nawo ano wenhamo. Inonzi leakage ano.

Kuti leakage Kuyerera anoratidza kunaka insulator rinoshandiswa zvaAtemisi capacitors. The nani insulator, kuti leakage Kuyerera duku. Pano, mumwe anogona kufunga ezvinhu ndiwo voltage dzakasvikwa capacitance akapiwa pane leakage kuitika inoyerera kuburikidza kuremedzwa nhengo. Saka, nokuda mutemo Ohm kuti tinogona ngaaverenge impedance yacho capacitor. Zvichava mukuru, leakage dzenzvimbo mumidziyo ano zvikamu zviduku microamps.

A zvishoma yakasiyana mufananidzo anotarira kana capacitor iri pachena kuti rakatumbuka ano. Current runoyerera pachena kuburikidza ngarava. Chikonzero ndechokuti pane muitiro dzose tiite-undoraira capacitor. A muitiro upi kuerera ano chokuita nokurasikirwa yayo nokuda pamberi mumweya iyi, kunze yezviri nemishonga waya varipo capacitance pamusoro capacitor nokuda kwayo pezvakaitwa, kureva kuchaja uye zvaikosha.

The zvemagetsi ehupfumi ari rapera chigadzirwa inotsamira zvinhu zvakawanda. Izvi zvinosanganisira chimiro, geometric kukura, mhando dielectric. Kune mhando dzakasiyana-siyana capacitors sechinhu dielectric anoshandiswa mune Vacuum, mhepo, mapurasitiki, Mika, bepa, girazi, Ceramics, aruminiyamu-electrolyte tantalum electrolyte.

Okupedzisira maviri mhando dzinonzi electrolytic capacitors, vanowanzoita vane yepamusoro vanokwanisa. Other capacitors vakadana dielectric mhando - bepa, zvedongo, girazi. Mumwe nomumwe wavo ane pachake zvachiri, maitiro avo pasi akasiyana parameters ane Magetsi, ayo maitiro uye kushanda.

Saka zvedongo capacitors kunowanzoitwa kushandiswa inonzwika apo kuti mukuru Frequency ruzha nematunhu electrolytic - nokuti inonzwika apo ruzha yakaderera frequencies. Uye pamwe chete yakafanana kubatana pakati zvedongo uye electrolytic capacitors, zvinoitika vakawanda Sefa kushandiswa zvinenge zvose namano. Muzviitiko zvose mugaba riri wakaiswa ukoshi yakadai 0,15 microfarads.

Zvakakosha kuziva pamberi shanduka capacitor, vanokwanisa dzavo dzinosiyana zvichienderana nzvimbo nokudzora pfundo. Izvi zvinoitwa kusandura bindepinde pakati capacitor kwamahwendefa. Sezvo nyaya inokosha ine shanduka capacitor, pane anonzi trimmer capacitors. Mavari, zvakare, vanokwanisa dzingasiyana - asi zvishoma uye chete panguva padariro midziyo kuchinja.

The Nomenclature inoshandiswa capacitors ndiyo huru - zvose dielectric mhando uye by design.
