Mumagetsi edunhu, vacuum-interrupter yekubata zvinhu zvinonyanya kuita 50-50 copper-chromium alloy.Anogona kugadzirwa nekuisa simbi yemhangura-chrome alloy sheet panzvimbo yepamusoro nechepazasi yekusangana pamusoro pechigaro chekubatanidza chakagadzirwa nemhangura isina oxygen.Zvimwe zvinhu, senge sirivheri, tungsten uye tungsten makomisheni, anoshandiswa mune mamwe madhizaini ekukanganisa.Iyo vacuum interrupter's contact structure ine simba guru pakutyoka kwayo, kusimba kwemagetsi uye nhanho yekutema ikozvino.
Iyo vacuum interrupter bellows inobvumira iyo inofambisa kubata kuti ishandiswe kubva kunze kweinovhiringidza yakavharirwa, uye inofanirwa kuchengetedza yakareba vacuum yakakwira pamusoro pehupenyu hunotarisirwa hwekushanda hweanovhiringidza.Mabhero anogadzirwa nesimbi isina tsvina ine ukobvu hwe 0.1 kusvika 0.2 mm.Hupenyu hwayo hwekuneta hunokanganisa nekupisa kunoitwa kubva kuarc.
Kuti vakwanise kuzadzisa zvinodiwa zvekutsungirira kwakanyanya mukuita chaiko, mabhero anogara achiedzwa kutsungirira mwedzi mitatu yega yega.Muedzo unoitwa mune yakazara otomatiki bvunzo kabhini nemafambiro akagadziridzwa kune yakafanira mhando.
Magungano ediki evacuum interrupters akatanga aunganidzwa uye akasungwa pamwechete muchoto chehydrogen-atmosphere.Chubhu yakabatana nemukati memuvharidzi yakashandiswa kuburitsa chinovhiringidza nepombi yekuvharisa yekunze uku chinovhiringidza chaichengetwa chiri pa400 °C (752 °F).
Mune mamwe mamiriro ezvinhu, vacuum circuit breaker inogona kumanikidza yazvino mudunhu kusvika zero pamberi pezvakasikwa zero (uye kudzoreredzwa kwezvino) munharaunda inochinja-chinja.Kana interrupter operation nguva isingafadzi maererano neAC-voltage waveform (kana arc yadzimwa asi macontacts achiri kufamba uye ionization haisati yaparara mu interrupter), voltage inogona kudarika gap's stand voltage.Izvi zvinogona zvakare- kubatidza arc, zvichikonzera kukurumidza kupfupika kwemhepo.Chero zvazvingaitika, oscillation inounzwa musystem iyo inogona kukonzera yakakosha pamusoro pemagetsi.Vagadziri vevacuum-interrupter vanogadzirisa izvi zvinonetsa nekusarudza zvinhu zvekubata uye magadzirirwo ekuderedza kutema kwazvino.Kuchengetedza michina kubva pamusoro pemagetsi, vacuum switch magiya anowanzo sanganisira mavhisi anosunga.
