Vacuum interrupter, inozivikanwawo sekuti vacuum switch chubhu, ndiyo yakakosha chikamu chepakati-yakakwirira voltage simba switch.Inonyanya kushandiswa kune simba rekufambisa uye kugovera kudzora hurongwa, uye inoshandiswawo kune kugovera masisitimu esimbi, mugodhi, peturu, kemikari, njanji, kutepfenyura, kutaurirana uye maindasitiri akakwira frequency heat.Vacuum interrupter ine maitiro ekuchengetedza simba. , kuchengetedza zvinhu, kudzivirira moto, kuputika-uchapupu, vhoriyamu shoma, hupenyu hurefu, mutengo wakaderera wekugadzirisa, kushanda kwakavimbika uye pasina kusvibiswa.Iyo vacuum interrupter yakakamurwa mukushandiswa kweanovhiringidza uye chinja chekutakura.Iyo inovhiringidza yedunhu inopwanya inonyanya kushandiswa mune substation uye magetsi grid zvivakwa mudhipatimendi remagetsi emagetsi.
Nyatsodzora kuvhara uye kuvhura kumhanya kwevacuum circuit breaker.Kune vacuum circuit breaker ine chimwe chimiro, mugadziri akatsanangura yakanakisa kuvhara kasi.Kana iyo yekuvharisa yekuvhara yevacuum yedunhu breaker yakanyanya kuderera, kupfeka kwekusangana kuchawedzera nekuda kwekuwedzera kwe pre breakdown nguva;Kana iyo vacuum yedunhu breaker ikabviswa, nguva yekumisa ipfupi, uye iyo yakanyanya arcing nguva haipfuure 1.5 simba frequency hafu wave.Izvo zvinodikanwa kuti kana ikozvino yayambuka zero kekutanga, iyo arc yekudzima kamuri inofanirwa kuve neyakakwana yekusimbisa simba.Kazhinji, zvinotarisirwa kuti sitiroko yekusangana mumagetsi frequency hafu wave ichasvika 50% - 80% yekurohwa kwakazara panguva yekutyora kwedunhu.Naizvozvo, kumhanya kwekuvhura kwemutsigiri wedunhu kunofanirwa kudzorwa zvakanyanya.Sezvo iyo arc yekudzima kamuri yevacuum wedunhu breaker kazhinji inotora brazing process, simba rayo remuchina harina kukwirira, uye kuramba kwayo vibration kwakashata.Kunyanya kuvharika kwekumhanya kwedunhu rinotyora kunokonzeresa kuzunguzika kukuru, uye kuchavawo nekukanganisa kukuru pamabhero, kuderedza hupenyu hwebasa remabhero.Naizvozvo, iyo yekuvharisa yekuvhara yevacuum yedunhu breaker inowanzoiswa se 0.6 ~ 2m / s.
