Vacuum interrupter yekuremerwa break switch (203)
Tsanangudzo pfupi yechigadzirwa:
Iyo yekunze inoshanda sisitimu inotyaira iyo inofamba inobata, iyo inovhura nekuvhara yakabatana dunhu.Iyo vacuum interrupter inosanganisira gidhi sleeve yekudzora inofamba kubata uye kudzivirira mabhero ekuvharira kubva pakumonyoroka, izvo zvaizopfupisa hupenyu hwayo zvakanyanya.
Kunyangwe mamwe mavacuum-interrupter dhizaini aine akareruka butt anobatika, anobatika anowanzo kuumbwa ane slots, mitsetse, kana grooves kunatsiridza kugona kwavo kupaza mafungu akakwira.Arc ikozvino inoyerera kuburikidza neakaumbwa mabatirwo anogadzira magineti masimba paarc column, izvo zvinoita kuti iyo arc yekuonana nzvimbo ifambe nekukurumidza pamusoro peiyo yekubata.Izvi zvinoderedza kupfekedzwa kwekubatana nekuda kwekukukurwa nearc, iyo inonyungudutsa simbi yekusangana panzvimbo yekubata.
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.
Painobvisa imwe chiyero chemazuva ano, panguva yekuparadzaniswa kwevane simba uye static contacts, ikozvino inoderera kusvika apo vanobatana vanongoparadzana, zvichikonzera kuwedzera kwakanyanya kwekupikisa pakati pemagetsi uye kukurumidza kuwedzera kwekushisa, kusvikira. iyo evaporation yesimbi ye electrode inoitika, uye panguva imwecheteyo, yakanyanya kusimba yemagetsi munda inoumbwa, zvichikonzera kubuda kwakasimba zvakanyanya uye gap kuputsika, zvichikonzera vacuum arc.Kana iyo magetsi frequency voltage iri pedyo ne zero, uye panguva imwechete, nekuda kwekuwedzera kwekusangana kwekuvhura kureba, Iyo plasma yevacuum arc inokurumidza kupararira kutenderedza.Mushure mekunge iyo arc yapfuura zero, iyo yepakati mugeji rekusangana inokurumidza kuchinja kubva kune conductor kuenda kune insulator, saka ikozvino inogurwa.Nekuda kwechimiro chakakosha chekubata, iyo gap yekubata inoburitsa longitudinal magineti panguva yeArcing.Iyi magineti inogona kuita kuti arc igovane zvakaenzana panzvimbo yekubata, kuchengetedza yakaderera arc voltage, uye kuita kuti vacuum arc yekudzimisa kamuri ive nekumhanyisa kudzoreredza kweiyo post arc dielectric simba, zvichikonzera diki arc simba uye diki corrosion rate.
