Chosokoneza cha vacuum cha MV VCB(ceramic chipolopolo, Voteji yovotera: 7.2kV-12kV)
Kufotokozera mwachidule za malonda:
Vacuum interrupter, yomwe imadziwikanso kuti vacuum switch chubu, ndiye gawo lapakati pamagetsi okwera kwambiri.Amagwiritsidwa ntchito kwambiri pamagetsi otumizira ndi kugawa mphamvu, ndipo amagwiritsidwanso ntchito ku machitidwe ogawa zitsulo, mgodi, mafuta, mankhwala, njanji, kuwulutsa, kulankhulana ndi mafakitale othamanga kwambiri. , kupulumutsa zinthu, kuteteza moto, kuphulika-kuphulika, voliyumu yaying'ono, moyo wautali, mtengo wotsika wokonza, ntchito yodalirika komanso yopanda kuipitsa.Chosokoneza cha vacuum chimagawidwa mukugwiritsa ntchito chosokoneza ndi chosinthira katundu.Chosokoneza chophwanyira dera chimagwiritsidwa ntchito makamaka mu substation ndi malo opangira magetsi mu dipatimenti yamagetsi yamagetsi.

Yang'anirani mosamalitsa kutseka ndi kutsegulira kwa liwiro la vacuum circuit breaker.Kwa ophwanya dera la vacuum ndi dongosolo linalake, wopanga watchula liwiro labwino kwambiri lotseka.Liwiro lotsekera la chopukutira dera ndi lotsika kwambiri, kukhudzana kumawonjezeka chifukwa chakuwonjezeka kwa nthawi yosweka;Pamene chotchinga chamagetsi chatsekedwa, nthawi ya arcing imakhala yochepa, ndipo nthawi yake yothamanga kwambiri sidutsa 1.5 mphamvu pafupipafupi theka la mafunde.Ndikofunikira kuti pomwe pano idutsa zero kwa nthawi yoyamba, chipinda chozimitsira arc chiyenera kukhala ndi mphamvu zokwanira zotchingira.Nthawi zambiri, zikuyembekezeka kuti sitiroko ya kukhudzana mu mphamvu pafupipafupi theka yoweyula adzafika 50% - 80% ya sitiroko zonse pa kuswa dera.Chifukwa chake, liwiro lotsegulira la wowononga dera liyenera kuyendetsedwa mosamalitsa.Monga chipinda chozimitsira cha arc cha vacuum circuit breaker nthawi zambiri chimatengera njira ya brazing, mphamvu yake yamakina sikwera, ndipo kugwedezeka kwake sikokwanira.Kuthamanga kwambiri kotseka kwa owononga dera kumayambitsa kugwedezeka kwakukulu, komanso kudzakhudza kwambiri mavumbi, kuchepetsa moyo wautumiki wa mavuvu.Chifukwa chake, liwiro lotseka la chopukutira dera nthawi zambiri limayikidwa ngati 0.6 ~ 2m / s.
