Chifukwa capacitors? kugwirizana capacitor

Zamagetsi capacitor - ndi chipangizo kuti angathe kusunga mlandu ndi mphamvu ya magetsi kumunda. Kwenikweni tichipeza awiri ochititsa (maelekitirodi) ankasiyana wosanjikiza dielectric. The makulidwe a dielectric ali nthawizonse laling'ono kwambiri kuposa kukula kwa zipangizo. Mu magetsi ofanana madera capacitor amaimira 2 ofukula zigawo kufanana (II).

Kuweta chizindikiro ndi wagawo

Pali ena mfundo zikuluzikulu zomwe chimatanthauza capacitor. Mmodzi wa iwo - izi ndi mphamvu (Latin kalata C), ndipo chachiwiri - pa opaleshoni voteji (Latin U). Magetsi capacitance (kapena chidebe) mu dongosolo SI amayezedwa farads (F). Ndipo ngati mphamvu unit wa 1 farad - kwambiri - pafupifupi sizinaikidwe mu ntchito. Mwachitsanzo, mtengo magetsi a Dziko Lapansi ndi microfarads 710 okha. Choncho, capacitance magetsi a capacitors nthawi zambiri amayezedwa zotumphukira wa farad makhalidwe: mu picofarads (PF) pa mtengo chochepa kwambiri cha capacitance (1pF = 1 / June ¹⁰ uF) mu microfarads (uF) kwa mokwanira lalikulu phindu lake (1 F = 1 / 10 ⁶ F). Kuwerengetsa capacitance magetsi, m'pofunika kugawa kuchuluka mlandu anapeza pakati maelekitirodi, ndi kusiyana kuthekera pa pakati pa gawo (capacitor voteji). Mlandu wa capacitor Pankhaniyi - ndi mlandu amasonkhana pa chimodzi cha zigawo chipangizo mu funso. 2 ochititsa chipangizo zimafanana mu ukulu koma amasiyana chizindikiro, kotero ndalama zawo nthawi zonse wofanana ziro. Mlandu wa capacitor ndi amayezedwa coulombs (cl), ndipo zinaperekedwa mwa kalata Q.

The voteji pa chipangizo chamagetsi cha

Chimodzi mwa magawo zofunika kwambiri nkhani imene ife ndi chipangizo kusokonezeka voteji - angathe kusiyana mfundo za ochititsa awiri capacitor, amene kumabweretsa kusokonezeka magetsi a wosanjikiza dielectric. The voteji pazipita limene chipangizo kusokonezeka zikachitika, anatsimikiza ndi mawonekedwe a akuwauza, katundu dielectric ndi wochindikala. kantchito pansi amene voteji pa mbale pafupi kusokoneza chipangizo chamagetsi cha, saloledwa. Normal opaleshoni voteji wa capacitor ndi zosakwana kusokonezeka kangapo (kawiri kapena katatu). Choncho, kusankha ayenera kulabadira voteji oveteredwa ndi mphamvu. Nthawi zambiri, makhalidwe amenewa anasonyeza pa chipangizo kapena pasipoti lapansi. Kutembenuza capacitor maukonde voteji wozingidwa ndi oveteredwa likuoneka kusokonezeka ake, ndi kupatuka pa mtengo mwadzina la capacitance ungathe kuti amasulidwe harmonics maukonde, ndi kutenthedwa chipangizo.

maonekedwe capacitors

capacitor kapangidwe akhoza kukhala yosiyanasiyana. Izo zimatengera mphamvu chipangizo magetsi ndi cholinga chake. Mu chipangizo ankaona magawo sayenera kutengera zinthu zina, kotero elekitirodi ndi mawonekedwe imene munda magetsi kwaiye milandu magetsi ali anaikira mu kusiyana kakang'ono pakati pa ochititsa capacitor. Choncho, iwo akhoza zigwirizana mitundu iŵiri concentric mbale awiri lathyathyathya kapena zonenepa awiri coaxial. Choncho, capacitors kungakhale cylindrical, ozungulira ndi lathyathyathya malingana ndi mawonekedwe a ochititsa lapansi.

capacitors zonse

Ndi chikhalidwe cha kusintha elektroomkosti capacitors anawagawa zipangizo ndi zonse kapena variable trimmers capacitance. Tiyeni tione mwatsatanetsatane aliyense wa mitundu. Zipangizo amene mphamvu sasintha pa opaleshoni, ndiko kuti, nthawi zonse (capacitance mtengo ukhoza zosiyanasiyana malire malinga kutentha), - ndi capacitors zonse. Palinso zipangizo zamagetsi, kusintha mphamvu ya magetsi pochita iwo amatchedwa zosintha.

Kodi Mzimuyo ndi capacitor C

capacitance magetsi zimadalira m'dera padziko wochititsa ake ndipo mtunda wa pakati pawo. Pali njira zambiri sinthani izi. Taonani capacitor, chomwe mitundu iwiri ya mbale: mafoni ndi lokhazikika. The mbale makina limayenda mogwirizana ndi amodzi potero kusintha capacitance magetsi a capacitor lapansi. Zosintha analogues ntchito zikhazikiko analogi zipangizo. Komanso, mphamvu zikhoza kusintha pa ntchito. Trimmer capacitors ali makamaka ntchito zida fakitale reader, mwachitsanzo chifukwa kutola mphamvu ndi kulephera empirically kuwerengera.

The capacitor mu dera la

Ankaona chipangizo mu DC dera amachititsa panopa kokha pamene kulolerana zake maukonde (kotero kuti mlandu kapena recharge chipangizo kwa voteji gwero). Kamodzi capacitor ndi mlandu kwathunthu, panopa kudzera si. Pamene chipangizo ndi mu dera ndi alternating panopa njira ya nawuza ndi lililonse ina yake ndi mzake. Pa kusinthana awo ali ndi oscillation nthawi ya ntchito sinusoidal voteji.

makhalidwe a capacitors

The capacitor malinga ndi chikhalidwe cha electrolyte ndi chuma umene wapangidwa, akhoza kukhala wouma, madzi, okusayidi michenga yopangira zida zamagetsi, zitsulo okusayidi. Phula-utakhazikika condensers bwino, zipangizozi ungatithandizire pansi katundu mkulu komanso kukhala ndi chuma chofunika odzikonda machiritso kuwonongedwa dielectric lapansi. M'nkhani zipangizo zamagetsi, youma mtundu wapamwamba kapangidwe, pang'ono zing'onozing'ono voteji dontho ndi kutayikira panopa. Pakadali ndi zipangizo youma ali otchuka kwambiri. The mwayi waukulu capacitors electrolytic ndi mtengo wotsika, yaying'ono kukula ndi lalikulu mphamvu ya magetsi. The okusayidi zofanana - kumalo ozizira (kugwirizana pachithunzichi kumabweretsa kusokonezeka).

Kodi kulumikiza

Kulumikiza capacitor mu dera ndi apano zonse chiri motere: zabwino (anode) panopa gwero olumikizidwa kwa elekitirodi amene ali ndi filimu okusayidi. Pankhani ya sanali kugwilizana cha kuwonongedwa dielectric angagwe. Pachifukwa ichi capacitors madzi ayenera zolumikizana mu mndandanda ndi mphamvu ndi AC gwero, ogwirizana mu mndandanda zigawo ziwiri zofanana. Kapena chifukwa okusayidi wosanjikiza pa maelekitirodi onse. Choncho, chipangizo chamagetsi sanali kumalo ozizira ikugwira ntchito Intaneti ndi onse zonse ndi sinusoidal panopa. Koma kuti ndi nthawi zina, mphamvu chifukwa amakhala theka. Unipolar capacitors magetsi ndi lalikulu kwambiri, koma akhoza kuwonjezekeredwa mu dera ndi alternating panopa.

The ntchito yaikulu ya capacitors

Mawu "capacitor" angamvele kwa ogwira ntchito ku makampani osiyanasiyana mafakitale ndi mamangidwe mabungwe. Popeza anachitira ndi mfundo ya ntchito, makhalidwe ndi njira thupi, tipeze chifukwa chake tiyenera capacitors Mwachitsanzo, mu kachitidwe kotunga mphamvu? kachitidwe batire izi ankagwiritsa ntchito yomanga ndi kukhazikitsanso zomera mafakitale mphamvu chinthu kudzudzulidwa PFC (maukonde ndi kumaliseche osafunika wa utuluke wake) kuti akhoza kuchepetsa mphamvu, kupulumutsa pa mankhwala cabling ndi kupulumutsa magetsi kwa ogula bwino khalidwe. Chisankho akadakwanitsira magwero mphamvu ndi njira kulumikiza mfundo ya zotakasika mphamvu (Q) mu Intaneti kachitidwe magetsi mphamvu (EPS) amakhudza kwambiri pa zachuma ndi luso zizindikiro ntchito EPS ntchito. Pali mitundu iwiri ya PFC: yopingasa ndi kotenga. Pamene yopingasa malipilo capacitor banki olumikizidwa ku kufanana pa basi substation ndi zimatchedwa shunt katundu (SHBK). Pamene kotenga malipilo batire monga mphamvu mizere ndi crosscuts otchedwa CCP (mndandanda malipilo chipangizo). Mabatire zigwirizana zipangizo osiyana kumene zolumukizidwa m'njira zosiyanasiyana: kulumikiza ndi capacitor pa mndandanda kapena kufanana. Pamene chiwerengero cha zipangizo mndandanda-olumikizidwa kumawonjezera mavuto. CCP komanso ntchito agwirizane mbali katundu, patsogolo zokolola ndi dzuwa ndi miyala-matenthedwe ng'anjo Arc (pamene CPC kudzera tiransifoma wapadera).

Mu madera ofanana mizere mphamvu ndi voltages kuposa 110 kV capacitance pansi ndiwo amaimira monga capacitors. EP mzere chifukwa mphamvu ya magetsi pakati pa ochititsa magawo osiyana ndi capacitance popangidwa ndi gawo wochititsa ndi nthaka. Choncho, kuwerengera modes maukonde ntchito, magawo kufala mzere, vuto malo mains capacitor katundu ntchito.

Ina ya malo a ntchito

Komanso akuti angamvele ku njanji antchito. Chifukwa capacitors iwo? Pa sitima ndi zipangizo deta magetsi ntchito kuchepetsa magetsi arcing waika kukhudzana, kuwongola ndi kugunda DC linanena bungwe kuchokera rectifiers ndi zimachitika choppers, ndi kubala m'badwo wa ofananira sinusoidal voteji ntchito zopangira Motors magetsi.

Komabe, mawu zambiri nkotheka kumva kuchokera mkamwa ya wailesi ankachita masewera. Chifukwa capacitors iye? Wailesi ya ntchito zawo kuti mkulu pafupipafupi mu atomu mafunde ali mbali ya Zosefera kusalaza, amapereka mphamvu, amplifiers, ndi PCB.

Mu mogwirizana chipinda aliyense wokonda galimoto angapeze angapo zipangizo izi. N'chifukwa chiyani tiyenera capacitors galimotoyo? Kumeneko ntchito mu amplifying zida lamayimbidwe kachitidwe chifukwa apamwamba phokoso kubalana.
