Kungani ama-capacitor evame ukwehluleka?

Ama-capacitor e-aluminium electrolyticziyisici esibalulekile samadivayisi amaningi kagesi futhi zidlala indima ebalulekile ekugcineni nasekukhipheni amandla kagesi. Kodwa-ke, naphezu kokubaluleka kwawo, ama-capacitor avame ukwehluleka, okubangela ukwehluleka futhi okungenzeka kulimaze lonke uhlelo. Ukuqonda izimbangela zokwehluleka kwe-capacitor kubalulekile ekuqinisekiseni ukuthembeka nokuphila isikhathi eside kwemishini kagesi.

Kunezizathu eziningana zokuthi kungani ama-capacitor evame ukwehluleka, esinye sezizathu ezivame kakhulu ukusetshenziswaama-capacitor e-aluminium electrolyticLawa ma-capacitor asetshenziswa kabanzi kumasekethe ngenxa yomthamo wawo ophezulu, izindleko eziphansi, kanye nezilinganiso ze-voltage eziphakeme. Kodwa-ke, uma kuqhathaniswa nezinye izinhlobo zama-capacitor, anempilo elinganiselwe, okungaholela ekungasebenzi kahle njalo kwemishini kagesi.

Esinye sezizathu eziyinhloko zokuthi kungani ama-capacitor e-aluminium electrolytic ehluleka ukuzwela kwawo ekushintsheni kwezinga lokushisa. Lawa ma-capacitor azwela kakhulu ekushintsheni kwezinga lokushisa, futhi ukuchayeka emazingeni okushisa aphezulu kungabangela ukuthi i-electrolyte engaphakathi kwe-capacitor yome, okuholela ekulahlekelweni kwamandla kanye nokwanda komthamo wokuvuza. Lokhu kungabangela ukuthi i-capacitor yonakale futhi ekugcineni ibangele ukuthi yehluleke.

Esinye isici esibangela ukwehluleka kwama-capacitor e-aluminium electrolytic ukuthambekela kwawo ekuwohlokeni ngokuhamba kwesikhathi. Ama-electrolyte asetshenziswa kula ma-capacitor asengozini yokuwohloka kwamakhemikhali, okungabangelwa yizinto ezahlukahlukene njengokushisa okuphezulu kokusebenza, ukucindezeleka kwe-voltage, kanye nokuchayeka ezintweni ezingcolisayo zemvelo. Njengoba i-electrolyte iwohloka, i-capacitance kanye ne-ESR (ukumelana nochungechunge olulinganayo) lwe-capacitor kuyashintsha, okuholela ekusebenzeni okunciphile kanye nokuthembeka.

Ngaphezu kokushisa nokuguga, esinye isizathu esenza ama-capacitor e-aluminium electrolytic avame ukwehluleka ukuthambekela kwawo ekukhuphukeni kwamandla kagesi kanye nogesi ogelezayo. Lawa ma-capacitor avame ukusetshenziswa kumasekethe okuphakelwa kwamandla kagesi lapho evezwa khona yiziphethu ezigelezayo eziphakeme kanye nogesi ogelezayo. Ngokuhamba kwesikhathi, ukuvezwa ngokuphindaphindiwe yiziphethu ezigelezayo eziphakeme kanye nogesi ogelezayo kungabangela ukuthi izingxenye zangaphakathi ze-capacitor ziwohloke, okuholela ekunciphiseni amandla kagesi kanye nokwanda kwe-ESR.

Ngaphezu kwalokho, ukwakheka kanye nekhwalithi yeama-capacitor e-aluminium electrolytickuzothinta nokuthembeka kwazo kanye nezinga lokwehluleka. Ama-capacitor ashibhile noma angaphansi kwesilinganiso angasebenzisa izinto ezisezingeni eliphansi kanye nezinqubo zokukhiqiza, okuholela emathubeni aphezulu okwehluleka kusenesikhathi. Ukusebenzisa ama-capacitor asezingeni eliphezulu, alinganiswe kahle emishinini kagesi kubalulekile ekunciphiseni ingozi yokwehluleka.

Ukuze kuncishiswe ingozi yokwehluleka kwe-capacitor, kubalulekile ukucabangela izimo nendawo lapho i-capacitor izosetshenziswa khona. Ukuphathwa kahle kokushisa, ukwehla kwamandla kagesi, kanye nokukhetha ngokucophelela ama-capacitor ngokusekelwe ezicini zawo kanye nezilinganiso zokuthembeka kungasiza ekwandiseni impilo yawo yesevisi futhi kunciphise ingozi yokwehluleka.

Ngamafuphi, ama-capacitor e-aluminium electrolytic ayimbangela evamile yokwehluleka kwemishini kagesi ngenxa yokuzwela kwawo ekushiseni, ukuguga, ukucindezeleka kwamandla kagesi, kanye nomsinga wamanzi ogelezayo. Ngokuqonda lezi zici nokuthatha izinyathelo zokuphepha ezidingekayo, njengokukhetha ama-capacitor asezingeni eliphezulu nokusebenzisa izimo zokusebenza ezifanele, unganciphisa amathuba okwehluleka kwe-capacitor futhi uqinisekise ukuthembeka kwemishini yakho kagesi.
