Vacuum interrupter kumashanyarazi make yamashanyarazi (604)

Mubice byumuzunguruko, ibikoresho bya vacuum-interrupter nibikoresho byibanze ni 50-50 umuringa-chromium.Birashobora gukorwa mugusudira umuringa - chrome alloy urupapuro hejuru no hepfo yo guhuza hejuru yintebe yo guhuza ikozwe mumuringa utagira ogisijeni.Ibindi bikoresho, nka silver, tungsten na tungsten, bikoreshwa mubindi bishushanyo mbonera.Imiterere ya vacuum ihagarika imiterere ifite uruhare runini mubushobozi bwayo bwo kumeneka, kuramba kwamashanyarazi nurwego rwo gutema.
Vacuum interrupter inzogera ituma itumanaho ryimuka rikorwa hanze yikigo, kandi rigomba gukomeza icyuho kirekire kirekire hejuru yubuzima buteganijwe bwo guhagarika ibikorwa.Inzogera ikozwe mubyuma bidafite ingese hamwe na mm 0.1 kugeza 0.2 mm.Ubuzima bwumunaniro bwabwo bugira ingaruka kubushyuhe bukorwa muri arc.

Kugirango bashobore kuzuza ibisabwa kugirango bihangane cyane mubikorwa nyabyo, inzogera ikorerwa ikizamini cyo kwihangana buri mezi atatu.Ikizamini gikorerwa mumashini yuzuye yikizamini hamwe ningendo zahinduwe muburyo bukwiye.
Inteko ziteranirizo za vacuum zabanje guteranyirizwa hamwe hanyuma zigashyirwa hamwe mu itanura rya hydrogène.Umuyoboro uhujwe n’imbere w’imbere wifashishijwe mu kwimura uwakoresheje pompe ya vacuum yo hanze mu gihe uwahagaritswe yagumishijwe kuri 400 ° C (752 ° F).
Mubihe bimwe na bimwe, icyuho cyumuzunguruko gishobora guhatira umuyoboro wumuzunguruko kugeza kuri zeru mbere ya zeru karemano (no guhindukira kwumuyaga) mukuzunguruka-kuzunguruka.Niba ibikorwa byo guhagarika igihe bitameze neza kubijyanye na AC-voltage yumurongo (mugihe arc yazimye ariko imibonano iracyagenda kandi ionisation itarakwirakwira), voltage irashobora kurenga icyuho cyihanganira voltage.Ibi birashobora kongera- gutwika arc, bitera gutembera gutunguranye.Muri ibyo aribyo byose, ihungabana ryinjijwe muri sisitemu ishobora kuvamo imbaraga zirenze imbaraga za voltage.Abakora Vacuum-interrupter bakemura ibyo bibazo muguhitamo ibikoresho byo guhuza hamwe nibishushanyo kugirango bagabanye gukata.Kurinda ibikoresho hejuru ya voltage, ibikoresho bya vacuum mubisanzwe birimo abafata surge.
