Kutheni capacitors? uqhagamshelo capacitor

capacitor zombane - sisixhobo ukuba sigcine isigxina namandla intsimi yombane. Ngokomthetho liphethe iperi ababhexeshi (electrode) ezahlulwe sisithuba umaleko Heating. Ububanzi Heating usoloko mncinci kakhulu ngobukhulu amacwecwe. Kwi-electric kwiisekethe ezilingana capacitor zibonakaliswe 2 ziqwempu nkqo parallel (II).

parameter kanye unit Basic

Kukho ezinye izinto ezisisiseko ezichaza capacitor. Omnye wabo - oku umthamo wayo (yesiLatini unobumba C), kwaye yesibini - le ombane yokusebenza (Latin U). capacitance Electrical (okanye isingxobo) kwinkqubo SI ulinganiswa farads (F). Ke njengeyunithi umthamo we-1 farad - eninzi - phantse asifake practice. Umzekelo, nesigxina yombane le uMhlaba yi microfarads 710 kuphela. Ngoko ke, lo capacitance yombane capacitors kwiimeko ezininzi ulinganiswa avela lwamaxabiso farad: in picofarads (PF) kwi ixabiso elincinane kakhulu capacitance (1pF = 1 / Juni ¹⁰ uF) e microfarads (uF) ukwenzela ixabiso layo elikhulu ngokwaneleyo (1 F = 1 / June ¹⁰ F). Ukubala capacitance umbane, kuyimfuneko ukuba yahlula imali kwentlawulo ofumbileyo phakathi electrode, umahluko kho phakathi umnqongo (ombane capacitor). Nesigxina capacitor kulo mzekelo - kuba intlawulo oluhlala enye amacwecwe kwefowuni umbuzo. Ukwenzela ababhexeshi 2 ifowuni ukuba ziyafana ubukhulu kodwa zahluke umqondiso, ngoko bawadibanise usoloko ulingana zero. Nesigxina capacitor ulinganiswa coulombs (Cl), kwaye otyunjwe Q. incwadi

Le ombane kwisixhobo

Enye i parameters zibalulekileyo ziqwalaselwe yi kuthi ke ombane isixhobo yokuwa - iinqobo umahluko okunokwenzeka izinikezeli amabini capacitor, nto leyo ekhokelela ekubeni yokuwa wombane umaleko Heating. Le ombane eliphezulu apho icebo breakdown kwenzeka, umiselwa imilo ababhexeshi, iipropati Heating kunye ubukhulu bayo. iimeko abasebenza phantsi apho ombane Emacebeni kufutshane yokuwa sombane, awavumelekanga. Normal yokusebenza ombane le capacitor lingaphantsi kwe-hlula izihlandlo eziliqela (amaxesha amabini okanye amathathu). Ngoko ke, lo ukhetho kufuneka sinikele ingqalelo ombane rated kunye nesikhundla. Kwiimeko ezininzi, ezi amaxabiso eboniswe kwisixhobo okanye nencwadana leyo yokundwendwela. Ivula capacitor womnatha ombane esingadlulanga kayi kusongela ukuwa kwayo, kunye ukutenxa kwexabiso elibekiweyo le capacitance kungakhokelela okukhutshwa harmonics womnatha, kunye nobushushu kwefowuni.

capacitors imbonakalo

uyilo capacitor kunokuba zahlukahlukene kakhulu. Kuya kuxhomekeka kwisixhobo amandla ombane kunye nenjongo yawo. Kwifowni ingqalelo parameters akufuneki iphenjelelwa yimiba yangaphandle, ngoko ke electrode abe imilo apho endle yombane aveliswa iindleko zombane buzinze umsantsa encinane phakathi izinikezeli capacitor. Ngoko, ke ingaba ziingxaki anazo amacandelo amabini concentric of iipleyiti ezimbini tyaba okanye iisilinda ezimbini yafakwa. Ngenxa yoko, le capacitors inokuba zezindlu, ungqukuva kwaye iflethi ngokuxhomekeke imilo izinikezeli.

capacitors njalo

Bubunjani capacitors utshintsho elektroomkosti zahlulwe izixhobo kunye izikhwezeli rhoqo okanye umahluko capacitance. Makhe sihlolisise ngokweenkcukacha nganye kwezi ntlobo. Devices ogama amandla ayitshintshi kulo msebenzi, oko kukuthi, lo rhoqo (ixabiso capacitance zisenako ziyahluka ngaphakathi kwemida ngokuxhomekeke ubushushu), - a capacitors rhoqo. Kukho kwakhona izixhobo zombane, ukutshintsha amandla alo zombane kule nkqubo, zibizwa ngokuba variables.

Yintoni egqibayo ukuba capacitor C

capacitance Electrical kuxhomekeke phezu kobuso umqhubi wayo umgama phakathi kwabo. Kukho iindlela ezininzi ungatshintsha kuphela ezi zicwangciso. Cinga capacitor, equka iintlobo ezimbini amacwecwe: mobile ezisisigxina. Incence ezinokususwa imenza ngokunxulumene ezisisigxina, ngaloo ndlela ukutshintsha capacitance wombane capacitor. Nesebenzayo analogue asetyenziswa izicwangciso izixhobo analog. Ngaphezu koko, umthamo zingatshintshwa ngexesha lokusebenza. capacitors Trimmer zisetyenziswa kakhulu ukuba izixhobo mveliso isicwangciso, umzekelo ukukhuthuza amandla kunye nokungakwazi ukubala empirically.

Le capacitor kwi kwisekethe

isixhobo ingakhangelwa kwisekethe DC uqhuba yangoku kuphela xa uquko kwi network (ngaloo kukho intlawulo okanye recharge isixhobo kwemvelaphi ombane). Xa capacitor igcwaliswe ngokupheleleyo, lo ezikhoyo akunjalo. Xa ifowuni yesiphaluka kunye alternating current iinkqubo ezibiza kunye nokuphatha enye yayo kunye nabanye. Ngexesha alternation sabo ithuba oscillation le ombane isicelo sinusoidal.

iimpawu capacitors

Le capacitor ngokutsho imeko electrolyte kunye nesixhobo apho yakhiwa, unokuba owomileyo, ulwelo, oxide semiconductor, oxide metal. condensers lulwelo-lupholile kakuhle, ezi zixhobo unako ukusebenza phantsi imithwalo omkhulu, impahla ezibalulekileyo ezifana self-linophiliso yokuwa Heating. Xa ingqalelo bezixhobo zombane, uhlobo owomileyo uyilo kunokuba elula, ombane drop mncane kunye ukuvuza yangoku. Okwangoku akukho izixhobo ezomileyo kakhulu zithandwa. Inzuzo ephambili capacitors electrolytic zezi zamaxabiso aphantsi, ubungakanani indawo kunye obunamandla zombane. Le oksayidi ezilingana - polar (uqhagamshelwano engachanekanga ikhokelela ekuphasalakeni).

Indlela ukudibanisa

Ohlanganisa capacitor kwisiphaluka kunye yangoku rhoqo ngolu hlobo lulandelayo: HIV (anode) umthombo yangoku eqhagamshelwe electrode leyo igutyungelwe kunye film oxide. Kwimeko ka-zokungathotyelwa yokuwa Heating zingenzeka. Kungenxa yesi sizathu capacitors lulwelo kufuneka lidibane kuthotho kunye AC ngamandla umthombo, sinxulumene kuthotho kumacandelo amabini twatse. Okanye ukuba umaleko oxide kuzo zombini electrode. Ngaloo ndlela, a isixhobo non-polar esebenza uthungelwano zombini rhoqo kunye current sinusoidal. Kodwa loo kwaye kwezinye iimeko, nto umthamo iba isiqingatha. capacitors zombane Unipolar linobungakanani gqitha, kodwa kufakwa ejikeleza kunye ifildi yangoku.

Eyona Ukusetyenziswa capacitors

Igama elithi "capacitor" unokuviwa ukusuka kubasebenzi kumashishini ezahlukeneyo mveliso kunye namaziko zoyilo. Ukuba iyitshinizele kunye nomgaqo ukusebenza, iimpawu kunye neenkqubo zomzimba, fumana isizathu sokuba kufuneka capacitors, umzekelo, kwiinkqubo isibonelelo samandla? Ezi nkqubo battery ezisetyenziswa kakhulu ukwakhiwa ngokutsha kwezityalo zoshishino ukululeka amandla factor PFC (network nxamnye ekubhobhozeni engamkelekanga nezingenayo) ezinokuthi ukunciphisa iindleko zamandla, ukonga iimveliso iingcingo ezihamab phantsi ukuhambisa umbane umboleki arcade games. Ukhetho ngokupheleleyo ngemithombo yamandla kunye nendawo uqhagamshelo indlela kwamandla lovukelo (Q) kuthungelwano lweenkqubo amandla ombane (EPS) inempembelelo ebalulekileyo nezalathi zentsebenzo ngokwezoqoqosho nangokwezobugcisa EPS nokusebenza. Kukho iindidi ezimbini PFC: ezinqamlezayo kunye longitudinal. Xa ibhanki imbuyekezo capacitor ezinqamlezayo ezinxulumene ngokunxuseneyo kwi kwisitishana ibhasi yaye ibizwa ngokuba umthwalo shunt (SHBK). Xa longitudinal imbuyekezo ibhetri iquka imigca amandla crosscuts ekuthiwa CCP (isixhobo imbuyekezo series). Iibhetri luqulathe izixhobo ezahlukeneyo ezinokuthi zibe ngeendlela ezahlukeneyo: ukudibanisa i capacitor kwi kuthotho okanye ngaxeshanye. Xa inani izixhobo series-enxulumene kwandisa ukungakhululeki. CCP wasebenzisa ukulungelelanisa imithwalo izigaba, ukuphucula imveliso kunye nokusebenza kunye esikrwada-thermal amaziko arc (xa CPC ngokusebenzisa abaguquli ezizodwa).

Xa iziphaluka ezilingana lwelayini amandla kunye yombane aphezulu kwama-110 kV capacitance phantsi luchazwa nje capacitors. EP line ngenxa amandla zombane phakathi izinikezeli lezigaba ezahlukeneyo kunye capacitance akhiwa umqhubi lesigaba kunye emhlabeni. Ngoko ke, ukubala iindidi womnatha yokusebenza, parameters umgca transmission, isiphoso indawo iimpawu mbane capacitor kusetyenziswa.

Enye iindawo isicelo

Kwakhona, lo gama savakala evela kubasebenzi kololiwe. Kutheni capacitors kuzo? On zikaloliwe kunye nezixhobo data sombane zisetyenziselwa ukunciphisa iiseti zoqhagamshelwano arcing zombane, smoothing i eliguquguqukayo DC imveliso evela rectifiers kunye Choppers ukubetha, kwaye avelise isizukulwana ombane twatsa sinusoidal ezisetyenziselwa amandla Iimoto zombane.

Noko ke, eli gama kunokwenzeka rhoqo ukuva emlonyeni radio engahlawulwayo. Kutheni capacitors naye? I radio lokusetyenziswa kwazo ukwenza aqhelelkileyo amaza, bayinxalenye ukwenziwa mpuluswa okucoca, izinto amandla, yokukhulisa, kunye PCB.

Xa isikhuseli egumbini zonke ungumzondeleli imoto Ungafumana isibini kwezi zixhobo. Kutheni sifuna i capacitors emotweni? Apho zisetyenziswa ngendlela iinkqubo ive izixhobo yokukhulisa for ezikumgangatho ophezulu sound ukuzala.
