Basa uye Basa reCapacitors mune Yemazuva Ano Electronics
Macapacitor anowanikwa kwose kwose munyika yemagetsi, achishanda sezvikamu zvakakosha izvo zvinoita huwandu hwakawanda hwemabasa anokosha. Ingave inowanikwa mumudziyo wakapfava wemumba kana yakaoma maindasitiri system, ma capacitor akakosha mukushanda uye kugona kwemaseketi emagetsi. Ichi chinyorwa chinotarisa mumabasa akasiyana-siyana ema capacitor, kuongorora misimboti yavo, mashandisirwo, uye maitiro emagetsi emazuva ano.
1. Kunzwisisa Nheyo dzeCapacitors
Pakati payo, capacitor is passiveelectronic chikamuiyo inochengeta simba remagetsi mundima yemagetsi. Inosanganisira mahwendefa maviri ekufambisa akaparadzaniswa ne dielectric material, iyo inoshanda se insulator. Kana magetsi akaiswa pamahwendefa, munda wemagetsi unokura uchiyambuka dielectric, zvichikonzera kuunganidzwa kwechaji yakanaka pandiro imwe uye nechaji isina kunaka pane imwe. Iri simba rakachengetwa rinogona kubva rasunungurwa kana richidiwa, zvichiita kuti capacitor inokosha mumashandisirwo akasiyana-siyana.
1.1Capacitance uye Zvisarudzo Zvayo
Kugona kwecapacitor kuchengeta charge inoyerwa nekugona kwayo, inotaridzwa mumafadhi (F). Capacitance inofananidzwa zvakananga nechepamusoro pemahwendefa uye dielectric nguva dzose yezvinhu zvinoshandiswa, uye inversely proportional kusvika kure pakati pemahwendefa. Mhando dzakasiyana dzema capacitor dzakagadzirwa nemhando dzakasiyana dzekugonesa kuti dzienderane nemashandisirwo chaiwo, kubva papicofarads (pF) mumaseketi akakwira-frequency kusvika farads mune supercapacitors anoshandiswa kuchengetedza simba.
2. Mabasa Akakosha eCapacitors
Macapacitors anoita akati wandei akakosha mabasa mumaseketi emagetsi, rimwe nerimwe richibatsira pakuita kwese uye kugadzikana kwehurongwa.
2.1Energy Storage
Rimwe remabasa ekutanga e capacitor kuchengetedza simba. Kusiyana nemabhatiri anochengeta simba remakemikari, macapacitor anochengeta simba remagetsi. Uku kugona kukurumidza kuchengetedza uye kuburitsa simba kunoita kuti ma capacitor ave akanaka kune maapplication anoda kukurumidza kuburitswa, senge mukupenya kwekamera, defibrillators, uye pulsed laser system.
Supercapacitors, rudzi rwepamusoro-capacitance capacitor, inonyanya kukosha nekuda kwekugona kwavo kuchengetedza simba. Ivo vanovhara mukaha pakati peakajairwa capacitor nemabhatiri, achipa yakakwira simba density uye nekukurumidza kuchaja / kuburitsa. Izvi zvinovaita vakakosha mukushandisa senge regenerative braking masisitimu mumotokari dzemagetsi uye magetsi ekuchengetedza.
