Tlhaloso e khuts'oane ea sehlahisoa:

Hona joale ho chopping ka vacuum circuit breaker ho itšetlehile ka khatello ea mouoane le thepa ea elektronike e hlahisoang ke thepa ea ho kopana.Boemo ba ho chopping bo boetse bo susumetsoa ke conductivity ea mocheso-ho theola mocheso oa mocheso, tlase ke boemo ba ho khaola.
Hoa khoneha ho fokotsa boemo ba hona joale boo ho rema ho hlahang ka ho khetha thepa ea ho ikopanya e fanang ka mouoane o lekaneng oa tšepe ho lumella hore hona joale ho fihle boleng bo tlaase haholo kapa boleng ba zero, empa sena ha se etsoe ka seoelo kaha se ama matla a dielectric hampe. .
Matla a phahameng a ho sireletsa: Ha a bapisoa le mecha ea phatlalatso e fapaneng e sebelisoang ka har'a vacuum ea potoloho ke mochine o phahameng oa dielectric.E molemo ho feta mecha eohle ea litaba ntle le moea le SF6, e sebelisoang ka khatello e phahameng.
Ha arc e buloa ka ho arola likhokahano sebakeng se se nang letho, tšitiso e etsahala ho zero ea pele ea hajoale.Ka tšitiso ea arc, matla a bona a dielectric a eketseha ho fihla ho nako ea likete ha a bapisoa le li-breaker tse ling.

(1) Mehato ea ho thibela ho overvoltage.Vacuum circuit breaker e na le ts'ebetso e ntle ea ho robeha.Ka linako tse ling ha ho rojoa moroalo oa inductive, ho phahama ho feteletseng ho hlahisoa lipheletsong tse peli tsa inductance ka lebaka la phetoho e potlakileng ea loop current.Ka hona, bakeng sa li-transformer tsa mofuta o omileng le lisebelisoa tse ling tse nang le khanyetso e fokolang ea motlakase, ho molemo ho kenya lisebelisoa tse sireletsang ho feta tekano, tse kang tšepe ea oxide arresters.
(2) Laola ka tieo mojaro oa hona joale.
Bokhoni ba ho jara bacuum circuit breaker bo bobe.Kaha ho kenngoa ha mocheso ho thehoa pakeng tsa ho kopana le khetla ea mochine oa potoloho ea vacuum, mocheso o amanang le ho kopana le molamu oa conductive o fetisoa haholo-holo ka molamu oa conductive.E le ho etsa hore mocheso oa ts'ebetso oa "vacuum circuit breaker" o se ke oa feta boleng bo lumelletsoeng, nako ea eona ea ho sebetsa e tlameha ho lekanyetsoa ka thata hore e be tlaase ho feta ea hona joale e lekantsoeng.
