Kubwezeretsa kwa Vacuum Arc kwa Vacuum Circuit Breaker
Vacuum yapamwamba imakhala ndi mphamvu zambiri za dielectric.Pa zero pano arc imazimitsidwa mwachangu kwambiri, ndipo mphamvu ya dielectric imakhazikitsidwa mwachangu kwambiri.Kubwerera uku kwa mphamvu ya dielectric ndi chifukwa cha chitsulo chosungunuka chomwe chimakhala pakati pa zolumikizana chimafalikira mwachangu chifukwa chosowa mamolekyu a gasi.Pambuyo pa kusokonezedwa kwa arc, mphamvu yochira pa ma microseconds ochepa oyambirira ndi 1 kV/µs sekondi kwa arc current ya 100A.
Chifukwa cha zomwe tazitchula pamwambapa za vacuum circuit breaker, imatha kuthana ndi zovuta zochira zomwe zimagwirizanitsidwa ndi zolakwika zazifupi popanda vuto lililonse.

Katundu wa zinthu zolumikizirana
Zida zolumikizirana ndi vacuum circuit breaker ziyenera kukhala ndi zinthu zotsatirazi.

Ntchito Vacuum Circuit Breaker
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.

Kukonzekera kozungulira kwa vacuum circuit breaker
Wowononga dera la vacuum ali ndi mawonekedwe odalirika kwambiri, moyo wautali wautumiki komanso nthawi yayitali yokonza ndi kukonza, koma sitingalakwitse kuti chopukutira chamagetsi sichifunika kukonza.Kukonzekera koyenera kumayenera kuyendetsedwa mosinthasintha malinga ndi malamulo oyenerera komanso kuphatikiza ndi zochitika zenizeni zogwirira ntchito.

Mawonekedwe

1. Arc imazimitsidwa mu chidebe chosindikizidwa, ndipo arc ndi mpweya wotentha siziwonekera.Monga gawo lodziyimira pawokha, chipinda chozimitsa cha arc ndichosavuta kukhazikitsa ndikusintha.
2. Chilolezo cholumikizana ndi chochepa kwambiri, kawirikawiri pafupifupi 10mm, ndi mphamvu yaing'ono yotseka, njira yosavuta komanso moyo wautali wautumiki.
3. Nthawi yozimitsa arc ndi yaifupi, mphamvu ya arc ndi yochepa, mphamvu ya arc ndi yaying'ono, kutayika kwa kukhudzana ndi kochepa, ndipo nthawi zosweka zimakhala zambiri.
