Aluminium electrolytic capacitorsziyingxenye ebalulekile yemishini eminingi kagesi futhi zidlala indima ebalulekile ekugcineni nasekukhipheni amandla kagesi.Kodwa-ke, naphezu kokubaluleka kwawo, ama-capacitor avame ukuhluleka, okubangela ukwehluleka futhi okungase kulimaze lonke uhlelo.Ukuqonda izimbangela zokuhluleka kwe-capacitor kubalulekile ekuqinisekiseni ukwethembeka nokuphila isikhathi eside kwemishini kagesi.
Kunezizathu eziningana zokuthi kungani ama-capacitor evame ukuhluleka, enye yezinto ezivame kakhulu ukusetshenziswai-aluminium electrolytic capacitors.Lawa ma-capacitor asetshenziswa kakhulu kumasekhethi ngenxa yamandla awo aphezulu, izindleko eziphansi, kanye nezilinganiso zamandla kagesi aphezulu uma kuqhathaniswa.Kodwa-ke, uma kuqhathaniswa nezinye izinhlobo ze-capacitor, zinesikhathi esilinganiselwe sokuphila, okungaholela ekuhlulekeni okuvamile kumishini kagesi.
Esinye sezizathu eziyinhloko ezenza ama-aluminium electrolytic capacitor ahluleke ukuzwela kwawo ekuguquguqukeni kwezinga lokushisa.Lawa ma-capacitor azwela kakhulu ekushintsheni kwezinga lokushisa, futhi ukuchayeka emazingeni okushisa aphezulu kungabangela ukuthi i-electrolyte ngaphakathi kwe-capacitor yome, okuholela ekulahlekelweni kwe-capacitance nokwanda kokuvuza kwamanje.Lokhu kungabangela ukuba i-capacitor yehle futhi ekugcineni ibangele ukuthi yehluleke.
Esinye isici esinomthelela ekuhlulekeni kwe-aluminium electrolytic capacitor ukuthambekela kwabo kokunciphisa ngokuhamba kwesikhathi.Ama-electrolyte asetshenziswa kulawa ma-capacitor asengozini yokuwohloka kwamakhemikhali, okungabangelwa izici ezihlukahlukene ezifana namazinga okushisa aphezulu okusebenza, ukucindezeleka kwamandla kagesi, nokuchayeka ezintweni ezingcolisa imvelo.Njengoba i-electrolyte iwohloka, i-capacitance kanye ne-ESR (ukumelana nochungechunge olulinganayo) kuyashintsha kwe-capacitor, okuholela ekunciphiseni ukusebenza nokuthembeka.
Ngaphezu kwezinga lokushisa nokuguga, esinye isizathu esenza i-aluminium electrolytic capacitor ivame ukuhluleka wukuthambekela kwabo ekukhuphukeni kwe-voltage kanye nokugeleza kwamandla.Lawa ma-capacitor avame ukusetshenziswa kumasekhethi okuphakelwa kukagesi lapho evezwa amaza agelezayo aphezulu kanye nama-voltage spikes.Ngokuhamba kwesikhathi, ukuchayeka ngokuphindaphindiwe kuma-currents aphezulu kanye nama-voltages kungabangela izingxenye zangaphakathi ze-capacitor ukuthi ziwohloke, okuholela ekunciphiseni kwe-capacitance kanye nokwanda kwe-ESR.
Ngaphezu kwalokho, umklamo kanye nekhwalithi yei-aluminium electrolytic capacitorsizophinde ithinte ukwethembeka kanye nezinga lokuhluleka.Ama-capacitor ashibhile noma asezingeni eliphansi angase asebenzise izinto zekhwalithi ephansi nezinqubo zokukhiqiza, okuholela emathubeni aphezulu okwehluleka ngaphambi kwesikhathi.Ukusebenzisa ama-capacitor ekhwalithi ephezulu, akalwe ngokufanele emishinini kagesi kubalulekile ekunciphiseni ubungozi bokwehluleka.
Ukuze unciphise ingozi yokuhluleka kwe-capacitor, kubalulekile ukucabangela izimo nendawo lapho i-capacitor izosetshenziswa khona.Ukuphatha okushisayo okufanelekile, ukwehla kwamandla kagesi, nokukhethwa ngokucophelela kwama-capacitor ngokusekelwe ekucacisweni kwawo kanye nezilinganiso zokuthembeka kungasiza ukunweba impilo yabo yesevisi futhi kunciphise ingozi yokwehluleka.
Kafushane, ama-aluminium electrolytic capacitor awumthombo ovamile wokwehluleka emishinini kagesi ngenxa yokuzwela kwawo ezingeni lokushisa, ukuguga, ukucindezelwa kwamandla kagesi, kanye namandla akhona.Ngokuqonda lezi zici nokuthatha izinyathelo zokuphepha ezidingekayo, njengokukhetha ama-capacitor ekhwalithi ephezulu nokusebenzisa izimo zokusebenza ezifanele, unganciphisa amathuba okuhluleka kwe-capacitor futhi uqinisekise ukuthembeka kwemishini yakho ye-elekthronikhi.
