Kungani ama-capacitors evame ukwehluleka?

I-Aluminium electrolytic capacitorsIngxenye ebalulekile yamadivayisi amaningi we-elekthronikhi futhi idlala indima ebalulekile ekugcinweni nasekudedeleni amandla kagesi. Kodwa-ke, naphezu kokubaluleka kwazo, ama-capacitors avame ukwehluleka, abangela ukwehluleka futhi alimaze lonke uhlelo. Ukuqonda izimbangela ze-capacitor ukwehluleka kubalulekile ekuqinisekiseni ukuthembeka nokuphila isikhathi eside kwemishini ye-elekthronikhi.

Kunezizathu eziningana zokuthi kungani ama-capacitors evame ukwehluleka, okunye okuvame kakhulu ukusetshenziswa kweI-Aluminium electrolytic capacitors. Lawa ma-capacitors asetshenziswa kabanzi kumasekethe ngenxa yokukhonkotha kwawo okuphezulu, izindleko eziphansi, kanye nezilinganiso eziphakeme ze-voltage. Kodwa-ke, uma kuqhathaniswa nezinye izinhlobo zama-capacitors, zinesikhathi sokuphila esilinganiselwe, esingaholela ekwehlulekeni okujwayelekile emishini ye-elekthronikhi.

Enye yezizathu eziphambili ze-Aluminium electrolytic capacitors yehluleka ukuzwela kwazo ekuguquguqukeni kwezinga lokushisa. Lawa ma-capacitors azwela kakhulu izinguquko zokushisa, futhi ukuvezwa kwamazinga okushisa aphezulu kungadala i-electrolyte ngaphakathi kwe-capacitor ukuze ome, okuholela ekulahlekelweni kwamakhono kanye nokwanda kwamanje. Lokhu kungadala ukuthi i-capacitor ibe yinciphile futhi ekugcineni ibangele ukuthi yehluleke.

Enye into enomthelela ekwehlulekeni kwama-capacitors we-aluminium electrolytic ngokuthambekela kwawo kokudicilela phansi ngokuhamba kwesikhathi. Ama-electrolyte asetshenziswe kuleli capacitors atholakala ekuwohlokeni kwamakhemikhali, okungabangelwa yizinto ezahlukahlukene ezifana namazinga okushisa aphezulu, ukucindezela kwe-voltage, nokuchayeka ekungcolisweni kwezemvelo. Njengoba i-electrolyte iwohloka, i-capacitance ne-ESR (ukumelana kochungechunge okulinganayo) koshintsho lwe-capacitor, okuholela ekusebenzeni okuncishisiwe nokwethenjwa.

Ngaphezu kokushisa nokuguga, esinye isizathu esenza ukuthi ama-capacito angu-Aluminium Electrolytic ajwayele ukwehluleka ukuhlukunyezwa kwawo ukukhulisa ama-voltage surtes kanye ne-ripple yamanje. Lawa ma-capacitors asetshenziswa kakhulu emasekethe okuhlinzekwa kwamandla lapho adalulwa khona kwi-Ripple Rursents ephezulu kanye nama-voltage spikes. Ngokuhamba kwesikhathi, ukuvezwa okuphindaphindiwe kumasondo aphezulu kanye nama-volitage angabangela ukuthi izakhi zangaphakathi zeCapacitor zinciphise, kuholele ekunciphiseni amandla futhi kwandiswe i-ESR.

Ngaphezu kwalokho, ukwakheka nekhwalithi yeI-Aluminium electrolytic capacitorsKuzothinta futhi ukuthembeka kwabo kanye nezinga lokuhluleka. Ama-capacitors ashibhile noma aphansi angasebenzisa izinto ezisezingeni eliphansi kanye nezinqubo zokukhiqiza, okuholela ekuphumeni okuphezulu kokwehluleka ngaphambi kwesikhathi. Kusetshenziswa ama-capacitors asezingeni eliphakeme, alinganiswe kahle emishini ye-elekthronikhi kubalulekile ukunciphisa ingozi yokwehluleka.

Ukunciphisa ubungozi bokuhluleka kweCapacitor, kubalulekile ukucubungula imibandela kanye nemvelo lapho i-capacitor izosetshenziswa khona. Ukuphathwa okufanele kwe-thermal, ukukhethwa kwamandla okuthengiswayo, nokukhethwa ngokucophelela kwama-capacitors kususelwa ekucacisweni kwabo nasekulinganisweni kwabo ukuthembeka kungasiza ukunweba impilo yabo yenkonzo futhi kunciphise ingozi yokwehluleka.

Ngamafuphi, abakwa-Aluminium electrolytic capacitors bangumthombo ojwayelekile wokwehluleka kwemishini kagesi ngenxa yokuzwela kwawo ekushiseni, ukuguga, ukucindezelwa kwamandla kagesi, kanye ne-ripple yamanje. Ngokuqonda lezi zinto nokuthatha izinyathelo zokuphepha ezidingekayo, njengokukhetha ama-capacitors asezingeni eliphakeme futhi kusetshenziswe izimo ezisebenzayo zokusebenza, unganciphisa amathuba okuhluleka kweCapacitor futhi uqinisekise ukuthembeka kwemishini yakho ye-elekkhali.
