Vacuum interrupter, yomwe imadziwikanso kuti vacuum switch chubu, ndiye gawo lapakati pamagetsi okwera kwambiri.Ntchito yayikulu ya vacuum interrupter ndikupangitsa kuti dera lapakati ndi lalitali lamagetsi lidutse mphamvu ya chipinda chozimitsira cha vacuum arc ya chipolopolo cha ceramic kudzera pakutchinjiriza kwabwino kwa vacuum mkati mwa chubu, chomwe chimatha kuzimitsa arc ndikupondereza zomwe zikuchitika. , kuti tipewe ngozi ndi ngozi.
Chosokoneza cha vacuum chimagwiritsa ntchito vacuum yapamwamba kuzimitsa arc pakati pa zolumikizana.Pamene zolumikizanazo zikuyenda motalikirana, pompopompo ikuyenda kudera laling'ono.Pali kuwonjezereka kwakukulu kwa kukana pakati pa kukhudzana, ndipo kutentha kumalo okhudzidwa kumawonjezeka mofulumira mpaka kuchitika kwa electrode-zitsulo evaporation.Panthawi imodzimodziyo, gawo lamagetsi ndilokwera kwambiri pamtunda wochepa wolumikizana.Kuwonongeka kwa gap kumapanga vacuum arc.Pamene kusinthasintha kwamakono kumakakamizika kudutsa zero chifukwa cha kukana kwa arc, ndipo kusiyana pakati pa ogwirizanitsa okhazikika ndi osuntha akukulirakulira, plasma yochititsa chidwi yopangidwa ndi arc imachoka pamphepete ndipo imakhala yosayendetsa.Pakalipano wasokonezedwa.

Ma AMF ndi ma RMF ali ndi mipata yozungulira (kapena yozungulira) yodulidwa kumaso kwawo.Maonekedwe a ma contacts amapanga mphamvu za maginito zomwe zimasuntha malo a arc pamwamba pa zolumikizana, kotero kuti arc sakhala pamalo amodzi kwa nthawi yayitali.Arc imagawidwa mofanana pamtunda wolumikizana kuti ukhalebe ndi mphamvu yochepa ya arc ndikuchepetsa kukokoloka.
Pambuyo potsirizira ndi kutsukidwa ndi electroplating ndi kuyang'ana kwa kuwala kwa mawonekedwe a pamwamba pa mbali imodzi yachitidwa, chosokonezacho chimasonkhanitsidwa.Solder ya vacuum yapamwamba imagwiritsidwa ntchito pamagulu a zigawozo, zigawozo zimagwirizana, ndipo zosokoneza zimakhazikika.Popeza ukhondo pa nthawi ya msonkhano ndi wofunika kwambiri, ntchito zonse zimachitika m'zipinda zaukhondo zokhala ndi mpweya wozizira.Mwanjira imeneyi, wopanga amatha kutsimikizira zosokoneza nthawi zonse komanso kuchuluka kokwanira mpaka 100 kA malinga ndi IEC/IEEE 62271-37-013.
