Kumeta kwakanthawi mu chopukusira dera lovumbulutsa kumadalira mphamvu ya nthunzi ndi mphamvu zotulutsa ma elekitironi pazolumikizana.The chopping mlingo umakhudzidwanso ndi matenthedwe madutsidwe-kutsitsa madutsidwe matenthedwe, m'munsi ndi chopping mlingo.
Ndikotheka kuchepetsa kuchuluka komwe kumeta kumachitika posankha chinthu cholumikizira chomwe chimapereka mpweya wokwanira wachitsulo kulola kuti mphamvu yapano ikhale yotsika kwambiri kapena mtengo wa zero, koma izi sizichitika kawirikawiri chifukwa zimasokoneza mphamvu ya dielectric. .
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.
Pamene arc imatsegulidwa ndikusuntha zolumikizana mu vacuum, kusokoneza kumachitika pa zero yoyamba.Ndi kusokonezeka kwa arc, mphamvu zawo za dielectric zimakwera mpaka nthawi zikwizikwi poyerekeza ndi zophulika zina.

(1) Njira zopewera kuphulika.Vacuum circuit breaker imakhala ndi ntchito yabwino yosweka.Nthawi zina pothyola inductive katundu, overvoltage yayikulu imapangidwa kumapeto kwa inductance chifukwa chakusintha mwachangu kwa loop current.Choncho, kwa owuma-mtundu thiransifoma ndi zipangizo zina otsika mphamvu voteji kukana, ndi bwino kukhazikitsa overvoltage zipangizo chitetezo, monga zitsulo okusayidi zomangira.
(2) Yang'anirani mwamphamvu katundu wapano.
Kuchulukirachulukira kwa vacuum circuit breaker ndikocheperako.Popeza kutchinjiriza matenthedwe amapangidwa pakati kukhudzana ndi chipolopolo cha vakuyumu dera wosweka, kutentha pa kukhudzana ndi conductive ndodo makamaka zimafalitsidwa pamodzi conductive ndodo.Kuti kutentha kwa ntchito ya vacuum circuit breaker kusapitirire mtengo wololeka, ntchito yake yamakono iyenera kukhala yochepa kwambiri kuposa yomwe idavotera pano.
