Kuchengetedza simba muma capacitors: kuongororwa kwemutakuri uye kushandiswa kwesimba remagetsi
Sechinhu chikuru chekuchengetera simba mumaseketi emagetsi, ma capacitor anochengeta simba muchimiro chesimba remagetsi. Kana maplate maviri e capacitor akabatana nesosi yemagetsi, machaji akanaka neasina kunaka anoungana pamaplate maviri pasi pesimba remagetsi, zvichigadzira mutsauko unogona kuitika uye zvinogadzira simba remagetsi rakasimba mu dielectric pakati pemaplate. Maitiro aya anotevera mutemo wekuchengetedza simba. Kuunganidzwa kwechaji kunoda basa kuti ukunde simba remagetsi, uye pakupedzisira kunochengeta simba muchimiro chesimba remagetsi. Kugona kwekuchengetedza simba kwe capacitor kunogona kuverengerwa nefomura E=21CV2, apo C ndiyo capacitance uye V ndiyo voltage iri pakati pemaplate.
Hunhu hwesimba remagetsi
Kusiyana nemabhatiri echinyakare anoshandiswa nesimba remakemikari, kuchengetwa kwesimba rema capacitor kwakavakirwa zvachose pakushanda kweminda yemagetsi chaiyo. Semuenzaniso, electrolyticma capacitorinochengetedza simba kuburikidza ne polarization effect ye oxide film pakati pemaplates ne electrolyte, iyo yakakodzera mamiriro anoda kuchaja nekukurumidza uye kuburitsa, senge power filtering. Supercapacitors (senge double-layer capacitors) dzinoumba chimiro che double-layer kuburikidza ne interface iri pakati pe activated carbon electrode ne electrolyte, zvichivandudza zvakanyanya huwandu hwesimba rekuchengetera simba. Nheyo dzayo dzakakamurwa muzvikamu zviviri:
Kuchengetedza simba remagetsi kaviri: Machaji anonyudzwa pamusoro pe electrode nemagetsi asingachinji, pasina makemikari, uye ane kumhanya kwekuchaja nekuburitsa simba nekukurumidza.
Faraday pseudocapacitor: Inoshandisa reactions dzinokurumidza dze redox dzezvinhu zvakaita se ruthenium oxide kuchengetedza machaji, zvine simba rakawanda uye simba rakawanda.
Kusiyana-siyana kwekusunungurwa kwesimba uye kushandiswa
Kana capacitor ikaburitsa simba, simba remagetsi rinogona kushandurwa nekukurumidza kuita simba remagetsi kuti ritsigire zvinodiwa ne high-frequency response. Semuenzaniso, muma solar inverters, ma capacitor anoderedza kushanduka kwemagetsi uye anovandudza kushanda zvakanaka kwesimba kuburikidza ne filtering uye connecting functions; muma power systems,ma capacitorgadzirisa kugadzikana kwegrid nekubhadhara simba rinoita reactive. MaSupercapacitor anoshandiswa kuzadza simba ipapo ipapo uye modulation yegrid frequency yemotokari dzemagetsi nekuda kwekugona kwavo kupindura millisecond.
Maonero Eramangwana
Nekubudirira mune zvesainzi yezvinhu (senge ma graphene electrodes), huwandu hwesimba rema capacitor huri kuramba huchiwedzera, uye mamiriro ekushandiswa kwawo ari kuwedzera kubva pamidziyo yemagetsi yechinyakare kuenda kuminda yemazuva ano yakadai sekuchengetera simba idzva uye ma grid akangwara. Kushandiswa zvakanaka kwesimba remagetsi hakuna kungosimudzira kufambira mberi kwetekinoroji chete, asiwo kwave chikamu chakakosha chekushandurwa kwesimba.
