I-Aluminiyam i-electrolytic capacitors ingahlala naphi na ukusuka kumawaka ambalwa eeyure ukuya kwiminyaka emininzi, kuxhomekeke kubushushu, i-ripple current, i-voltage stress, i-capacitance, umgangatho we-electrolyte, uyilo lokutywina, kunye nendawo yokusebenza. I-capacitor elinganiswe iiyure ze-2,000 kwi-105 C ayithethi ukuba iya kuphumelela emva kweeyure ze-2,000 ekusebenziseni okuqhelekileyo. Kuthetha ukuba inxalenye ivavanyelwa ubomi obulinganisiweyo phantsi kweemeko zobushushu obuphezulu.
Kwizixhobo zangempela, ukuba i-capacitor isebenza kwiqondo lokushisa eliphantsi kwaye ngaphakathi kwemida yayo yombane, ubomi bayo benkonzo bunokuba bude kakhulu. Kungenxa yoko le nto iinjineli kunye namaqela abathengi zihlala zisebenza ngokusondeleyo abavelisi be-aluminium electrolytic capacitor Ukukhetha uthotho oluchanekileyo, ukukala kwamandla ombane, umlinganiselo wobushushu, kunye nebakala lobomi kwisicelo ngasinye.
Kutheni uBomi bonke bungumba ophambili
I-Aluminiyam i-electrolytic capacitors isetyenziswa ngokubanzi kumbane, abaqhubi be-LED, ii-inverters, iitshaja, ii-motor drives, ulawulo lwamashishini, izixhobo zomsindo, izixhobo zendlu, kunye neenkqubo zamandla avuselelekayo. Zixabiswa ngenxa yobuchule obuphezulu, ubungakanani obubambeneyo, kunye nokusebenza kakuhle kweendleko.
Nangona kunjalo, ziqulethe i-electrolyte. Ngokuhamba kwexesha, ubushushu kunye noxinzelelo lombane kunokubangela ilahleko ye-electrolyte, ukunyuka okulinganayo kokunganyangeki, ukunciphisa amandla, ukuvuza utshintsho lwangoku, kwaye ekugqibeleni ukusilela. Oku kwenza ucwangciso lobomi lubaluleke ngakumbi kwisixhobo ekulindeleke ukuba siqhube ngokuqhubekayo.
Ukuqonda Kukalwe kuBomi bonke
Iidatadata zeCapacitor zihlala zidwelisa ixesha lobomi kwiiyure kubushushu obuphezulu, obunje:
- Iiyure ze-1,000 nge-105 C
- iiyure ezingama-2,000 nge-105 C
- Iiyure ezingama-5,000 nge-105 C
- Iiyure ezingama-10,000 nge-105 C
Oku akufani nobomi bokwenyani kwimveliso. I-capacitor elinganiswe kwiiyure ze-5,000 kwi-105 C inokuhlala ixesha elide ukuba isebenza kwi-65 C, kunye ne-moderate ripple current kunye ne-ventilation efanelekileyo.
Ubomi obulinganisiweyo yireferensi yovavanyo olulawulwayo. Iinjineli ziyisebenzisela ukuthelekisa uchungechunge lweemveliso kunye nokuqikelela ubomi benkonzo phantsi kweemeko zangempela.
Umthetho Weqondo Lobushushu
Ubushushu yeyona nto inkulu echaphazela ubomi be-aluminiyam electrolytic capacitor. Njengoko ubushushu buphakama, i-electrolyte yoma ngokukhawuleza kwaye ukuguga kweekhemikhali zangaphakathi kuyakhawuleza.
Umgaqo wobunjineli oqhelekileyo kukuba ubomi be-capacitor bunokuba ngokuphindwe kabini kwi-10 C yokunciphisa ubushushu obungundoqo, ngaphakathi kwemida yokusebenza efanelekileyo. Umzekelo, i-capacitor elinganiswe iiyure ezingama-2,000 kwi-105 C inokuhlala ixesha elide kwi-85 C, kwaye ixesha elide lihlala kwi-65 C.
Lo mgaqo luqikelelo kuphela. Ubomi bokwenene buxhomekeke kuyilo lwe-capacitor kunye neemeko zokusebenza, kodwa ibonisa ukuba kutheni ulawulo lwe-thermal lubaluleke kakhulu.
I-Ripple yangoku kunye nobushushu
I-Ripple yangoku idala ukufudumeza kwangaphakathi ngaphakathi kwe-capacitor. Nokuba umoya ojikelezileyo awushushu kakhulu, i-ripple current ephezulu inokunyusa ubushushu obuphambili be-capacitor.
Umsinga womoya ophezulu unokukhokelela ku:
- Ukunyuka ngokukhawuleza kwe-electrolyte
- Ubushushu bangaphakathi obuphezulu
- Ukunyuka kwe-ESR
- Ukuncitshiswa kwesakhono
- Ubomi benkonzo obufutshane
- Ukukhupha umoya okunokwenzeka okanye ukusilela
Xa ukhetha ii-capacitors, iinjineli kufuneka zithelekise ukulinganisa kwangoku kunye neemeko zesekethe zangempela. Uthembekile abavelisi be-aluminium electrolytic capacitor nikezela ngeenkcukacha zangoku eziqhekezayo ukunceda abayili baphephe ukuthoba.
Uxinzelelo lwamandla kagesi
Ukusebenzisa i-capacitor kufutshane ne-voltage yayo ephezulu elinganiselweyo kunokunyusa uxinzelelo. Ukusebenzisa umda wombane ofanelekileyo kunokuphucula ukuthembeka.
Umzekelo, isekethe ene-24V DC inokusebenzisa i-capacitor elinganiswe ngaphezulu kwe-24V, ngokuxhomekeke kwi-ripple, ukunyuka, ubushushu, kunye nomda wokhuseleko. Kuyilo oluthembeke kakhulu, iinjineli zithintela ukusebenza kwee-capacitors ngokuqhubekayo kumda opheleleyo.
Nangona kunjalo, ukugqithiswa kwamandla ombane kakhulu kunokuchaphazela ubungakanani, ixabiso, kunye nokusebenza ngamanye amaxesha, ngoko ke ukhetho kufuneka lulinganiswe.
