1. Izindlela ezihlukene zokugcina ugesi
Ngokwemibandela ethandwa kakhulu, ama-capacitor agcina amandla kagesi. Amabhethri agcina amandla amakhemikhali aguqulelwe kumandla kagesi. Owokuqala uwushintsho olungokomzimba nje, lokhu okugcina kuwushintsho lwamakhemikhali.
2. Isivinini kanye nemvamisa yokushaja nokukhipha kuhlukile.
Ngoba i-capacitor igcina ngokuqondile ukushaja. Ngakho-ke, isivinini sokushaja nokukhipha sishesha kakhulu. Ngokuvamile, kuthatha imizuzwana embalwa kuphela noma amaminithi ukushaja ngokugcwele i-capacitor enamandla amakhulu; ngenkathi ukushaja ibhethri ngokuvamile kuthatha amahora ambalwa futhi kuthintwa kakhulu izinga lokushisa. Lokhu futhi kunqunywa uhlobo lokusabela kwamakhemikhali. Ama-Capacitor adinga ukushajwa futhi ashajwe okungenani izikhathi ezingamashumi ezinkulungwane ukuya kumakhulu ezigidi zezikhathi, kuyilapho amabhethri ngokuvamile anezikhathi ezingamakhulu noma izinkulungwane kuphela.
3. Ukusetshenziswa okuhlukile
Ama-Capacitor angasetshenziselwa ukuhlanganisa, ukuqaqa, ukuhlunga, ukuguqula isigaba, i-resonance kanye nezingxenye zokugcina amandla okukhishwa kwamanje okukhulu ngokuphazima kweso. Ibhethri isetshenziswa kuphela njengomthombo wamandla, kodwa futhi ingadlala indima ethile ekuqiniseni amandla kagesi kanye nokuhlunga ngaphansi kwezimo ezithile.
4. Izici ze-voltage zihlukile
Wonke amabhethri ane-voltage yegama. Ama-voltage ahlukene ebhethri anqunywa ngezinto ezihlukene zama-electrode. Okufana nebhethri le-lead-acid engu-2V, i-nickel metal hydride 1.2V, ibhethri ye-lithium engu-3.7V, njll. Ibhethri liyaqhubeka nokushaja nokuphuma kule voltage isikhathi eside kakhulu. Ama-Capacitor awanazo izidingo ze-voltage, futhi angasukela ku-0 kuye kunoma iyiphi i-voltage (i-voltage yokumelana ne-superscripted ku-capacitor iyipharamitha yokuqinisekisa ukusetshenziswa okuphephile kwe-capacitor, futhi ayihlangene nezici ze-capacitor).
Phakathi nenqubo yokukhipha, ibhethri “izoqhubeka” ngokuzimisela eduze ne-voltage yegama ngomthwalo, kuze kube yilapho ingakwazi ukubambelela futhi iqala ukwehla. I-capacitor ayinaso lesi sibopho "sokugcina". I-voltage izoqhubeka nokwehla nokugeleza kusukela ekuqaleni kokukhishwa, ukuze kuthi lapho amandla anele kakhulu, i-voltage yehlile ezingeni "elibi".
5. Amajika wokushaja nokukhipha ahlukile
Ijika lokushaja nokukhipha i-capacitor liwumqansa kakhulu, futhi ingxenye eyinhloko yenqubo yokushaja nokukhipha ingaqedwa ngokuphazima kweso, ngakho-ke ifaneleka kakhulu okwamanje, amandla aphezulu, ukushaja okusheshayo nokukhipha. Leli jika eliwumqansa linenzuzo enqubweni yokushaja, likuvumela ukuthi liqedwe ngokushesha. Kodwa kuba yingozi ngesikhathi sokukhishwa. Ukwehla ngokushesha kwamandla kagesi kwenza kube nzima kuma-capacitor ukuthi ashintshe amabhethri ngokuqondile endaweni yokuphakela amandla. Uma ufuna ukungena emkhakheni wokunikezwa kwamandla, ungawuxazulula ngezindlela ezimbili. Enye iwukusebenzisa ngokuhambisana nebhethri ukuze ufunde kumandla nobuthakathaka bomunye nomunye. Okunye ukubambisana nemojula ye-DC-DC ukuze kulungiswe ukushiyeka okungokwemvelo kwejika le-capacitor discharge, ukuze i-capacitor ibe nokuphuma kwamandla kagesi kuzinzile ngangokunokwenzeka.
6. Ukuba nokwenzeka kokusebenzisa ama-capacitor ukushintsha amabhethri
Amandla C = q/ⅴ(lapho u-C eyi-capacitance, q inani likagesi elishajwa yi-capacitor, futhi v umehluko ongaba khona phakathi kwamapuleti). Lokhu kusho ukuthi lapho i-capacitance inqunywa, u-q/v uyinto engaguquki. Uma kufanele uyiqhathanise nebhethri, ungakwazi ukuqonda okwesikhashana u-q njengomthamo webhethri.
Ukuze sicace kakhudlwana, ngeke sisebenzise ibhakede njengesifaniso. I-capacitance C ifana nobubanzi bebhakede, futhi amanzi ayinani likagesi q. Yiqiniso, lapho ububanzi buba bukhulu, amanzi amaningi angabamba. Kodwa ingabamba malini? Kubuye kuncike ekuphakameni kwebhakede. Lokhu kuphakama yi-voltage esetshenziswa ku-capacitor. Ngakho-ke, kungashiwo ukuthi uma kungekho umkhawulo ophezulu we-voltage, i-farad capacitor ingagcina wonke amandla kagesi omhlaba!
uma unezidingo zebhethri, sicela usithinte nge[i-imeyili ivikelwe]
