Chii chinonzi capacitor, uye chii kuti

Achitsanangura kuti yakadaro capacitor, tinofanira kunyatsonzwisisa kwomuviri hwaro basa uye nemamiriro hunokosha che ose zvakawanda kana zvishoma chakakomba pamusoro wemagetsi.

Condenser - ndiko chinhu chine remudunhu magetsi, zvinosanganisira vaviri conductive ndiro, chimwe nechimwe unotora pakatarisana chiratidzo magetsi mutariri. Plates vakaparadzana nevanhu ane insulator, runovabatsira kuramba mhosva.

Kune mhando dzakawanda kuputira zvinhu yaishandiswa capacitors, kusanganisira Ceramics, Mika, tantalum uye polystyrene. Zvinowanzoshandiswa anogadzira zvinhu capacitors uye insulators zvakadai semhepo, pepa epurasitiki. Mumwe nomumwe izvi zvinhu zvinobudirira kunodzivisa ari capacitor mahwendefa kubva kuonana nomumwe.

Chii chinonzi capacitor?

Shoko rokuti "capacitor" ndozvavava kukwanisa kwayo yokuchengetera yemagetsi mutariri. The chairema capacitance ndiye Farad.

Kana kupikisa capacitor muzvitoro 1 pendant pane zvinogona musiyano pakati ndiro dzayo 1 volt, zvino ane kukwanisa ukoshi mumwe farad. Kutaura zvazviri, chikwata ichi chakanyanya guru dzinobatsira zvikuru mafomu. Typical capacitance tsika kushandisa capacitors kuwira mukati neeSultan milifarad (10.3 F) microfarads (10-6 F) uye picofarads (10-12 F).

Ndezvipi capacitors?

Kuti Vanzwisise capacitor chii, zvakakodzera kufunga inokosha mhando chikamu ichi, zvichienderana nechinangwa, zvinhu zviri kushanda uye mhando dielectric.

Electrolytic capacitors zvinoshandiswa mumatunhu apo mukuru vachikwanisa kunodiwa. Vazhinji zvinhu izvi polar. Kwakajairika zvinhu kwavari - kana tantalum aruminiyamu. Aluminum Electrolytic capacitors vari isingadhuri zvikuru uye yainyanya kushandiswa. Zvisinei, tantalum kuva substantially chikuru volumetric kunyatsoshanda uye vane kwazvo magetsi maitiro.

Tantalum capacitors vane somunhu dielectric kuti tantalum oxide. High kuvimbwa, zvakanaka kakawanda unhu, zvakawanda kushanda tembiricha. Vari zvinowanzoshandiswa zvemagetsi midziyo apo mukuru azvipire vanokwanisa pane miganhu diki. Nokuda kwayo zvakanakira anobudiswa akawanda zvinodiwa pakati Electronics indasitiri.

Zvazvakashatira tantalum capacitors anogona kunzi kune aikanganiswa ari kupomba-kuitika uye pamusoro-voltage, uye hama kudhura mishonga iyi.

Power capacitors vari yemanyorero kushandiswa dzakakwirira voltage enyika. Ivo anoshandiswa nevakawanda kudzikamisa Nokurasikirwa musimba mitsetse, uye kuvandudza simba chinhu maindasitiri zvivako. Made mukuru-metallized polypropylene firimu nokushandiswa chaiwo vasiri hunokachidza impregnation pamwe insulating mafuta.

Angava nokuzviremekedza destruct inoti dzakawanda kukuvara, izvo zvinovapa dzokuwedzera kuchengeteka uye anowedzera upenyu basa.

Ceramic capacitors vane dielectric zvinhu sezvo zvedongo. Vari ne mukuru functionality yacho uchishandisa voltage, kuvimbika, kurasikirwa yakaderera uye vakaderera mutengo.

Kuwanda kugona kwavo siyana kubva picofarads shoma kusvika 0.1 microfarads. Ndiye pari imwe inonyanya kushandiswa mhando capacitors zvaishandiswa zvemagetsi michina.

Silver Mica capacitors yakatsiva kwakapararira rapfuura Mika zvinhu. Ivai mukuru pakusimba, munhu hermetic pekugara uye kukwanisa guru muzana chikwata vhoriyamu.

kushandiswa kwakapararira esirivha-waMika capacitors chinonditadzisa nekaupenyu navo zvinodhura.

In pabepa metallized capacitor electrode rakagadzirwa nhete aruminiyamu foil, uyewo dielectric, pakaitwa pepa akaiswa mushonga wokuuraya zvikukutu (wakaumbwa) kana mvura dielectric. Ivo zvinoshandiswa yakaderera-Frequency redhiyo nematunhu ari kumusoro dzenzvimbo. Zvinoitika chisingakoshi.

Nei kudiwa capacitor

Kune akawanda mienzaniso kushandisa capacitors nenzira dzakasiyana-siyana zvinangwa. Zvikurukuru, vari kushandiswa chaizvo kuchengetera vana analoginen anonongedzera uye digitaalinen uye mashoko. Shanduka capacitors zvinoshandiswa foni kuti Frequency kuchinja uye setup kuti telecommunication michina.

Muenzaniso mumwe mafomu yavo kushandisa zvinyorwa simba. Ikoko, zvinhu izvi kuita mashandiro rimire (mupise) the kunogadzirisika voltage panguva goho namano izvi. Ivo ringashandiswawo nenzira voltage multipliers kuti generating yakakwirira voltage, kwazvo kanoverengeka mazano voltage. Condensers vari zvinowanzoshandiswa dzakasiyana-siyana voltage converters, uninterruptible simba wedzerai mano kuti makombiyuta, etc.

Achitsanangura kuti capacitor yakadaro, hatigoni kutaura kuti maatomu akafanana izvi zvinogona kushanda rakaisvonaka dzigare mairi kuti maerekitironi. Zvisinei, chokwadi ndechokuti kushanda ichi ane zvimwe zvausingakwanisi nokuda non-akakodzera zvechadenga vakashandisa insulating dielectric. Zvisinei, capacitor ane pfuma refu zvakakwana yokuchengetera zvemagetsi simba kana akochonorwa kubva kuchaja redunhu, saka rinogona kushandiswa kwenguva pfupi simba.

Nokuda kwayo ehupfumi yakasiyana zvokunyama zvinhu izvi akashandiswa zvikuru iri paindaneti uye magetsi maindasitiri, nhasi kashoma chero zvemagetsi chigadzirwa haibatanidzi kanenge chimwe chazvo zvakadaro chero chinangwa.

Achiratidza, tinogona kutaura kuti capacitor - chinhu chaizvo chikamu hombe siyana zvigadzirwa uye magetsi namano, pasina izvozvo zvaizova zvisingafungidziriki kufambira mberi mune zvesayenzi uye unyanzvi hwokugadzira zvinhu.

Ndizvo zvinotaurwa capacitor!
