Ama-capacitors adlala indima ebalulekile ezingxenyeni ze-elekthronikhi.Noma ngabe bangama-capacitors okuphepha, ama-capacitors we-ceramic, ama-capacitors e-monolithic, ama-capacitors amafilimu noma ama-varistors, angabhekana nengozi yokuqhekeka.ICapacitor Breakdown iyinto edalwe yinto ebangelwa amandla enkambu kagesi etholwa yi-dielectric edlula umkhawulo wayo.Lokhu kuvame ukwenzeka lapho amacala aqhekeka ama-athomu noma ama-molecule ukwenza ugesi, acekele phansi izakhiwo zawo zokufaka.
Ngakho-ke, yini ngempela ebangela ukuba i-dielectric inflation ye-capacitor ichithwe?Kunezizathu ezimbalwa eziphambili: Okokuqala, ngesinye sezizathu ezivame kakhulu ukuthi i-voltage esebenzayo idlula inani lokumelana nenani le-capacitor;Okwesibili, ikhwalithi empofu ye-capacitor, efana nokuvuza okukhulu kwamanje, kuzodala ukuthi izinga lokushisa likhulise kancane, ngaleyo ndlela kunciphise amandla okufakwa;Ekugcineni, ukubuyela emuva kokuxhuma kwe-caparity capacitor noma ukuxhumana okungalungile ku-AC Power Supply nakho kuzodala ukuwohloka.
Lapho i-capacitor ikhefu phansi, amandla ayo okubuyisa ancike kuhlobo lwe-dielectric.Uma i-dielectric i-gesi noma uketshezi, ukuwohloka kuvame ukubuyela emuva, okungukuthi, bayazibuyisela imithombo yezindaba.Kepha ama-dielectric aqinile, ukwephuka akunakuphikiswa, okusho ukuthi uma ukugqashuka kwenzeka, i-capacitor ayikwazi ukubuyela esimweni sayo sokuqala.
Ngakho-ke, ungakugwema kanjani ukuqhekeka kwe-dielectric of capacitors?Okokuqala, ukukhetha izinto ezinamandla aphezulu wokufakelwa kubalulekile.Okwesibili, qiniseka ukuthi ukufakwa kuwubukhulu obufanele futhi obungenakungcola okunjenge-bubble yomoya noma umswakama.Ngaphezu kwalokho, ukwakhiwa okunengqondo kokusatshalaliswa kwenkundla kagesi ukugwema ukuqina kwamandla kagesi ezindaweni ezithile ezindaweni ezithile nakho isilinganiso esibalulekile sokuvimbela.Lapho ukhetha izakhi ezifana nama-capacitors okuphepha, ama-capacitors we-ceramic, ama-capacitors we-monolithic, ama-capacitors wefilimu, kanye nama-varitors, ukukhetha abakhiqizi bokuqala abanesinyathelo esibalulekile ekuvinjelweni kweCapacitor.
Ngamafuphi, isizathu esiyinhloko sokuqhekeka kwe-capacitor ukuthi ukufakwa kwe-dielectric kubhujiswa futhi kwenzeka.Lokhu kungadalwa yi-voltage esebenzayo edlula ama-handstand voltage voltage voltage voltage, izinkinga zekhwalithi yeCapacitor, noma ukuxhumana okungalungile kwe-polarity.Ukuqonda lezi zimbangela nokuthatha izindlela ezifanele zokuvimbela zibalulekile ekuqinisekiseni ukusebenza okufanele kwe-capacitor kanye nokwelula impilo yayo yenkonzo.
