Kufotokozera mwachidule za malonda:

Cholakwika chikachitika m'dongosolo, zolumikizana ndi wosweka zimasunthidwa ndipo chifukwa chake arc imapangidwa pakati pawo.Pamene zonyamulira zamakono zimakokedwa, kutentha kwa zigawo zawo zolumikizira kumakhala kwakukulu kwambiri chifukwa cha ionization.Chifukwa cha ionization, malo olumikizana amadzazidwa ndi nthunzi wa ma ion abwino omwe amatulutsidwa kuchokera pazolumikizana.
Kachulukidwe wa nthunzi zimadalira panopa mu arcing.Chifukwa cha kuchepa kwa mafunde apano kutsika kwawo kwa nthunzi kugwa komanso pambuyo pa ziro zomwe zilipo, sing'angayo imapezanso mphamvu yake ya dielectric yomwe imapatsa kachulukidwe ka nthunzi kuzungulira zolumikizanazo.Chifukwa chake, arc sibwereranso chifukwa mpweya wachitsulo umachotsedwa mwachangu pamalo olumikizirana.

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.
