Vacuum interrupter yekutengesa kunze TD-25.8/630-20 (186)
Tsanangudzo pfupi yechigadzirwa:
Vacuum interrupter chinhu chemagetsi vacuum chinoshandisa yakakwira vacuum inoshanda insulating arc yekudzima svikiro uye inoziva basa rekudzima remagetsi redunhu neaviri emazita akavharirwa muvacuum.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.Nenzira iyi, iyo inovhiringidza ikozvino kugona uye hupenyu hwesevhisi yevacuum interrupter inovandudzwa.
Mune mamwe mamiriro ezvinhu, vacuum circuit breaker inogona kumanikidza yazvino mudunhu kusvika zero pamberi pezvakasikwa zero (uye kudzoreredzwa kwezvino) munharaunda inochinja-chinja.Kana interrupter oparesheni nguva isingafadzi maererano neAC-voltage waveform (kana arc yadzimwa asi macontacts achiri kufamba uye ionization haisati yaparara mune inovhiringidza), voltage inogona kudarika gap's stand voltage.Izvi zvinogona kubatidzazve arc, zvichikonzera kukurumidza kupfupika kwemhepo.Chero zvazvingaitika, oscillation inounzwa musystem iyo inogona kuguma nekunyanya overvoltage.
Mazuva ano, nekudzikira kwazvino kutema, vacuum circuit breakers haizokonzeresa kuwandisa kunogona kuderedza insulation kubva kumidziyo yakatenderedza.
