Vacuum interrupter, yomwe imadziwikanso kuti vacuum switch chubu, ndiye gawo lapakati pamagetsi okwera kwambiri.Ntchito yayikulu ya vacuum interrupter ndikupangitsa kuti dera lapakati ndi lalitali lamagetsi lidutse mphamvu ya chipinda chozimitsira cha vacuum arc ya chipolopolo cha ceramic kudzera pakutchinjiriza kwabwino kwa vacuum mkati mwa chubu, chomwe chimatha kuzimitsa arc ndikupondereza zomwe zikuchitika. , kuti tipewe ngozi ndi ngozi.
Vacuum circuit breaker ili ndi sing'anga yotchinga kwambiri kuti arc iwonongeke poyerekeza ndi chophwanya chigawo china.Kupanikizika mkati mwa vacuum interrupter ndi pafupifupi 10-4 torrent ndipo pa kuthamanga uku, mamolekyu ochepa kwambiri amapezeka mu chosokoneza.Chowotcha dera la vacuum chimakhala ndi zinthu ziwiri zodabwitsa.
Mphamvu yotchinga kwambiri: Poyerekeza ndi zida zina zotsekera zomwe zimagwiritsidwa ntchito pavuto lophwanyira dera ndi sing'anga yapamwamba kwambiri ya dielectric.Ndi bwino kuposa TV zina zonse kupatula mpweya ndi SF6, amene ntchito pa kuthamanga kwambiri.

Khalani tcheru

Yang'anirani mwamphamvu kutseka ndi kutsegula liwiro la vacuum circuit breaker.
Kwa chopukutira chamagetsi chokhala ndi mawonekedwe enaake, wopanga adatchula 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.
