Vacuum interrupter yomwe imadziwikanso kuti vacuum switch chubu, ndiye gawo loyambira lamagetsi apamwamba kwambiri.Ntchito yake yayikulu ndikudula ma arc kudzera pakutchinjiriza kwa vacuum mumagetsi apamwamba kwambiri ndikuletsa magetsi mwachangu kuti mupewe ngozi ndi ngozi.Amagwiritsidwa ntchito kwambiri pamagetsi amagetsi otumizira ndi kuwongolera kugawa, amagwiritsidwanso ntchito muzitsulo, migodi, mafuta, mafakitale amafuta, njanji, kuwulutsa, kulumikizana, mafakitale apamwamba kwambiri opangira magetsi.Amadziwika ndi kupulumutsa mphamvu, kupulumutsa zinthu, kuteteza moto, umboni wa kuphulika, mawu ang'onoang'ono, moyo wautali, mtengo wotsika wokonza, ntchito yodalirika komanso yosawononga.Chosokoneza cha vacuum chikhoza kugawidwa m'mitundu ingapo, imodzi ya ophwanya dera ndi ina ya kusintha kwa katundu, kwa contactor, kwa recloser.
Mndandanda wazinthuzi umapangidwa ndi kuyika nthawi imodzi-conductive magawo a dera la vacuum interrupter ndikusintha kupita ku epoxy resin material insulation.Kunja kwa vacuum interrupter sikukhudzidwa ndi chilengedwe chakunja.Kuthekera kwa kunja kwa kunja sikungakhudzidwe ndi fumbi, chinyezi, nyama yaing'ono, condensation ndi contamination.The mankhwala ali ndi ubwino zambiri, monga mkulu dielectric mphamvu, amphamvu nyengo kukana ntchito, kamodzi-ciecuit miniaturization, zolimba dongosolo, mkulu kudalirika ndi kukonza kwaulere.
