Namuhla, lapho imikhiqizo yokugcina amandla idlondlobala, ama-supercapacitor (ama-farad-level capacitor) anezici zokugcina amandla njengamandla aphezulu, i-ultra-high current, i-ultra-wide working range, ukuphepha okuphezulu kakhulu, nokuphila isikhathi eside kuyasetshenziswa. iyodwa, futhi ihlanganiswe neminye imikhiqizo yokugcina amandla.Ukusetshenziswa okuhlanganisiwe kuba okujwayelekile.Kubasebenzisi, kubaluleke kakhulu ukukhetha i-supercapacitor efanelekile.
Yiziphi izimo lapho ama-supercapacitor azosebenza kuzo?
1) Amandla aphezulu asheshayo, njengedivayisi yokukhipha i-UAV;
2)Ukunikezwa kwamanje kwesikhashana, njengamathoshi amaphoyisa;
3)Izimo zokusheshisa njalo (eziphansi) kanye nokwehlisa ijubane (phezulu), njengokubhuleka amadivaysi okuthola amandla;
4)Izimoto zikadizili ziqalwa esimweni sezulu esibanda kakhulu noma esimweni sokuhluleka kwebhethri;
5)Gcina ugesi wokuphehla amandla omoya, ukuphehla amandla elanga ashisayo, amandla enuzi nezinye izikhumulo zokuphehla ugesi;
6) Zonke izinhlobo zempilo ende, ukuthembeka okuphezulu, ukunganakekeli, amandla amakhulu okusekela amandla okusekela amandla;
Uma udinga idivayisi enezici zamandla aphezulu kanye nenani elithile lamandla ukuze ushayele izinto zikagesi, ezingalungiswa isikhathi eside, kanye nekhono lokusebenza ebangeni elibanzi lokushisa, ikakhulukazi uma izimfuneko zokuphepha ziqinile ngokuqhathaniswa kokuthi minus 30 40 degrees, sekuyisikhathi sokukhetha i-supercapacitor efanelekile.
Ulwazi okufanele ukwazi ngaphambi kokukhetha i-supercapacitor
Ngakho-ke hlobo luni lwe-supercapacitor olungahlangabezana nezidingo zakho?Yiziphi izici ezibalulekile zama-supercapacitor?Imingcele yayo eyinhloko yi-voltage (V), amandla (F) kanye nesilinganiso samanje (A).
Izidingo zamandla, isikhathi sokukhipha kanye nezinguquko zikagesi wesistimu ekusetshenzisweni okukhethekile kwama-supercapacitor zidlala indima ebalulekile ekukhetheni imodeli.Ngamagama alula, izinhlobo ezimbili zamapharamitha kufanele zicaciswe: 1) Ibanga le-voltage esebenzayo;2) Inani lokukhipha amandla noma ukuthi okukhiphayo kwamanje kuthatha isikhathi esingakanani.
Ungabala kanjani i-supercapacitor capacitance edingekayo
(1) Ukushintshashintsha njalo, okungukuthi, lapho okwamanje nobude besikhathi kusimo sokusebenza se-supercapacitor kuhlala njalo: C=It/( Vwork -Vmin)
Isibonelo: i-voltage eqala ukusebenza i-Vwork=5V;I-voltage enqunyiwe yokusebenza i-Vmin=4.2V;isikhathi sokusebenza t=10s;ugesi osebenzayo I=100mA=0.1A.Amandla adingekayo yilawa: C =0.1*10/(5 -4.2)= 1.25F
Kulokhu, ungakhetha umkhiqizo onamandla we-5.5V1.5F.
(2) Amandla aqhubekayo, okungukuthi, lapho inani lokukhipha amandla lingashintshi: C*ΔU2/2=PT
Isibonelo, ukukhishwa okuqhubekayo ngaphansi kwamandla angu-200KW imizuzwana engu-10, ububanzi be-voltage esebenzayo ngu-450V-750V, amandla okusebenza adingekayo: C=220kw10/(7502-4502)=11F
Ngakho-ke, i-capacitor (uhlelo lokugcina amandla) olunamandla angu-11F ngaphezu kuka-750V lungahlangabezana nalesi sidingo.
Uma i-capacitance ebaliwe ingekho phakathi kwebanga leyunithi eyodwa, ama-supercapacitor amaningi angaxhunywa ochungechungeni futhi ahambisane ukuze enze imojuli ukuze ahlangabezane nezidingo ezithile zamakhasimende.
Ifomula yokubala ehambisanayo enama-capacitor amaningi: C=C1+C2+C3+…+Cn
Ifomula yokubala yochungechunge lwama-Multi-capacitor: 1/C=1/C1+1/C2+…+1/Cn
Iziphakamiso zeminye imikhiqizo
(1) Imikhiqizo yochungechunge lwe-high-voltage inezinzuzo ezimweni eziningi
Yiziphi izinzuzo zemikhiqizo ye-high-voltage (2.85V kanye ne-3.0V)?
Inkomba yokuphila (impilo yomjikelezo we-1,000,000) ihlala ingashintshiwe, futhi amandla athile kanye namandla athile akhuphuka ngaphansi kwevolumu efanayo.
Ngaphansi kwesimo samandla angapheli namandla, ukunciphisa inani lamayunithi kanye nesisindo sesistimu iyonke kungathuthukisa ukuklama kwesistimu.
(2) Ukuhlangabezana nezidingo ezikhethekile
Uma kunezidingo ezikhethekile zohlelo lokusebenza, ireferensi yevelu ye-voltage elula ayisho lutho.Isibonelo, izinga lokushisa eliphezulu elingaphezu kuka-65℃, imikhiqizo yochungechunge engu-2.5V iyisinqumo esihle.Kufanele kuqashelwe ukuthi, njengazo zonke izingxenye ze-electrochemical, izinga lokushisa le-ambient lizothinta kakhulu impilo yama-supercapacitor, futhi impilo izophindwa kabili kukho konke ukwehla okungu-10 ℃ endaweni yokushisa ephezulu.
Isakhiwo kanye nezinto ze-electrode zama-supercapacitors azichazwanga kuleli phepha, ngoba imingcele engalinganiselwe inokubaluleka okuncane ekukhethweni kwangempela kwama-supercapacitor.Kumele kuqashelwe ukuthi ayikho idivayisi yokugcina amandla endaweni yonke, futhi ukusetshenziswa okuhlangene kwamadivayisi amaningi okugcina amandla kube yisinqumo esingcono kakhulu.Ngokufanayo, ama-supercapacitor asebenzisa amanye amadivaysi okugcina amandla ukuze aqhubekisele phambili izinzuzo zawo, futhi abuye abe yinsakavukela.
Ukuze uthenge izingxenye ze-elekthronikhi, udinga ukuthola umkhiqizi onokwethenjelwa kuqala.I-JYH HSU(JEC) Electronics Ltd (noma i-Dongguan Zhixu Electronic Co., Ltd.) inohlu olugcwele lwamamodeli e-varistor nama-capacitor anekhwalithi eqinisekisiwe.I-JEC iphumelele isitifiketi se-ISO9001:2015 yokuphathwa kwekhwalithi.Siyakwamukela ukuxhumana nathi ngezinkinga zobuchwepheshe noma ukubambisana kwebhizinisi.Iwebhusayithi yethu esemthethweni: www.jeccapacitor.com
