Zogulitsa
Chosokoneza cha vacuum cha MV VCB(ceramic chipolopolo, Voteji yovotera: 7.2kV-12kV)
Kufotokozera mwachidule za malonda:
Chophulitsa chomwe chimagwiritsa ntchito vacuum ngati cholumikizira cha arc chimatchedwa vacuum circuit breaker.Mu chophwanyira dera ichi, cholumikizira chokhazikika komanso chosuntha chimatsekeredwa mu chosokoneza chotsekedwa kotheratu.Arc yatha chifukwa zolumikizira zimasiyanitsidwa ndi vacuum yayikulu.Amagwiritsidwa ntchito kwambiri pamagetsi apakatikati kuyambira 11 KV mpaka 33 KV.
Pamene arc imatsegulidwa ndikusuntha zolumikizana mu vacuum, kusokoneza kumachitika pa zero yoyamba.Ndi kusokonezeka kwa arc, mphamvu zawo za dielectric zimawonjezeka mpaka nthawi zikwizikwi poyerekeza ndi zina zowonongeka.Zinthu ziwiri zomwe zili pamwambazi zimapangitsa kuti zowonongeka zikhale zogwira mtima, zochepetsetsa komanso zotsika mtengo.Moyo wawo wautumiki ndi waukulu kwambiri kuposa wina aliyense woyendetsa dera, ndipo pafupifupi palibe kukonza komwe kumafunikira.
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.
Khalani tcheru
Kuwongolera mosamalitsa kukhudzana ndi travel.The sitiroko ya vacuum circuit breaker ndi yayifupi.Nthawi zambiri, kugunda kwa chotchinga chamagetsi chovotera 10 ~ 15kV ndi 8 ~ 12mm kokha, ndipo kulumikizana paulendo ndi 2 ~ 3mm yokha.Ngati sitiroko yolumikizana ikukwera kwambiri, kupsinjika kwakukulu kumapangidwa pamivuvulo pambuyo poti wosweka wozungulira watsekedwa, kuwononga mavuvuwo ndikuwononga vacuum mu chipolopolo chosindikizidwa cha wowononga dera.Osaganiza molakwika kuti mtunda wawukulu wotsegulira ndiwopindulitsa kuzimitsa arc, ndipo onjezerani mayendedwe olumikizana ndi ophwanya dera la vacuum.
