Chifukwa chiyani ma capacitors nthawi zambiri amalephera?

Aluminium electrolytic capacitorsndizofunikira kwambiri pazida zambiri zamagetsi ndipo zimagwira ntchito yofunika kwambiri pakusunga ndi kutulutsa mphamvu zamagetsi. Komabe, ngakhale kufunikira kwawo, ma capacitors nthawi zambiri amalephera, zomwe zimapangitsa kulephera komanso kuwononga dongosolo lonse. Kumvetsetsa zomwe zimayambitsa kulephera kwa capacitor ndikofunikira kuti zitsimikizire kudalirika komanso moyo wautali wa zida zamagetsi.

Pali zifukwa zingapo zomwe ma capacitors nthawi zambiri amalephera, chimodzi mwazofala kwambiri ndikugwiritsa ntchitoaluminium electrolytic capacitors. Ma capacitor awa amagwiritsidwa ntchito kwambiri m'mabwalo chifukwa cha kuchuluka kwawo, kutsika mtengo, komanso ma voliyumu apamwamba kwambiri. Komabe, poyerekeza ndi mitundu ina ya capacitors, amakhala ndi moyo wochepa, zomwe zingayambitse kulephera kawirikawiri pazida zamagetsi.

Chimodzi mwa zifukwa zazikulu zomwe ma aluminiyamu electrolytic capacitors amalephera ndikukhudzidwa kwawo ndi kusinthasintha kwa kutentha. Ma capacitor awa amakhudzidwa kwambiri ndi kusintha kwa kutentha, ndipo kukhudzana ndi kutentha kwapamwamba kungapangitse electrolyte mkati mwa capacitor kuti aume, zomwe zimapangitsa kuti capacitance iwonongeke komanso kuwonjezeka kwa kutayikira panopa. Izi zitha kupangitsa kuti capacitor ikhale yonyozeka ndipo pamapeto pake imalephera.

Chinthu chinanso chomwe chimapangitsa kulephera kwa ma aluminium electrolytic capacitors ndi chizolowezi chawo chonyozeka pakapita nthawi. Ma electrolyte omwe amagwiritsidwa ntchito mu ma capacitorswa amatha kuwonongeka ndi mankhwala, omwe amatha chifukwa cha zinthu zosiyanasiyana monga kutentha kwapamwamba kwa ntchito, kupanikizika kwa magetsi, komanso kukhudzana ndi zowonongeka zachilengedwe. Pamene electrolyte ikuipiraipira, capacitance ndi ESR (mofanana kukana mndandanda) wa capacitor amasintha, zomwe zimapangitsa kuchepa kwa magwiridwe antchito ndi kudalirika.

Kuphatikiza pa kutentha ndi ukalamba, chifukwa china chomwe ma aluminiyamu electrolytic capacitors nthawi zambiri amalephera ndizovuta zawo pakukwera kwamagetsi ndi ma ripple current. Ma capacitor awa nthawi zambiri amagwiritsidwa ntchito m'mabwalo operekera magetsi komwe amakumana ndi mafunde othamanga kwambiri komanso ma voteji. M'kupita kwa nthawi, kuwonetseredwa mobwerezabwereza kwa mafunde apamwamba ndi ma voltages kungachititse kuti zigawo zamkati za capacitor ziwonongeke, zomwe zimapangitsa kuchepetsa mphamvu komanso kuwonjezeka kwa ESR.

Komanso, kapangidwe ndi khalidwe laaluminium electrolytic capacitorszidzakhudzanso kudalirika kwawo ndi kulephera kwawo. Ma capacitor otsika mtengo kapena otsika amatha kugwiritsa ntchito zida zotsika komanso njira zopangira, zomwe zimapangitsa kuti pakhale mwayi wolephera msanga. Kugwiritsa ntchito ma capacitor apamwamba, ovotera moyenera pazida zamagetsi ndikofunikira kuti muchepetse chiopsezo cholephera.

Kuti muchepetse chiopsezo cha kulephera kwa capacitor, ndikofunikira kuganizira momwe zinthu zilili komanso malo omwe capacitor idzagwiritsidwe ntchito. Kuwongolera koyenera kwa kutentha, kutsika kwa magetsi, ndikusankha mosamala ma capacitor kutengera momwe amapangira komanso kudalirika kwawo kungathandize kukulitsa moyo wawo wautumiki ndikuchepetsa chiwopsezo cha kulephera.

Mwachidule, ma aluminiyamu electrolytic capacitors ndi omwe amayambitsa kulephera pazida zamagetsi chifukwa cha chidwi chawo pakutentha, kukalamba, kupsinjika kwamagetsi, komanso kuthamanga kwamagetsi. Pomvetsetsa zinthuzi ndikutenga njira zodzitetezera, monga kusankha ma capacitor apamwamba kwambiri ndikugwiritsa ntchito machitidwe oyenera ogwiritsira ntchito, mukhoza kuchepetsa mwayi wa kulephera kwa capacitor ndikuwonetsetsa kudalirika kwa zipangizo zanu zamagetsi.
