China VD4 mndandanda wa vacuum circuit-breakers ndi zida zopangira ma switchgear m'nyumba.Chonde lemberani ROCKWILL kuti mupeze zofunikira zapadera.VD4-R mndandanda wapakati ma voltage vacuum circuit breakers okhala ndi makina ogwirira ntchito opangira m'nyumba amakhala ndi njira yopangira mizati.Pando iliyonse imakhala ndi chosokoneza cha vacuum chomwe chimakutidwa ndi utomoni pomwe silinda imawumbidwa chifukwa cha njira yapadera yopangira.Njira yomangira iyi imateteza chosokoneza cha vacuum ku mantha, kuipitsidwa ndi kukhazikika.
VCB VS1 12kV 630A M'nyumba High-voltage Vacuum Circuit Breaker:
Mtunda wapakati: 210mm
Mtundu wa ngolo yamanja
Kawiri kasupe ntchito makina
Malo ogwirira ntchito: (makamaka malo omwe akufunika kuchitidwa pafupipafupi)
1.the magetsi kulamulira ndi chitetezo mu mafakitale.
2.mabizinesi amigodi.
3.zomera zamagetsi.
4.zigawo.
Ikhoza kukhazikitsidwa mu kabati yosinthira kapena kuikidwa pa ngolo yamanja.
Ntchito yokhazikika komanso kukhazikitsa kosavuta.
Ubwino wa Vacuum Circuit Breaker
1.Mapangidwe osavuta.
2. Adapt ultra low resistance type vacuum interrupter.
3.Adapt kukhathamiritsa ndi modular kasupe ntchito makina.
4.Zoyenera nthawi ndi ntchito pafupipafupi.
5.Kukonza kwaulere ndi moyo wautali wautumiki.
6.Ntchito yodalirika kwambiri.
Mikhalidwe Yachilengedwe
Kutentha kozungulira: - 40°C~+40°C (pansi pa 35°C mkati mwa maola 24)
Chinyezi chofananira: ≤95% (avareji yatsiku ndi tsiku) kapena ≤90% (avareji ya pamwezi)
Kutalika: ≤ 1000m
