Iyo China VD4 yakatevedzana vacuum circuit-breakers zvishandiso zvemukati switchgear kuisirwa.Ndokumbira ubate ROCKWILL kune zvakakosha zvekuisa zvinodiwa.VD4-R yakatevedzana yepakati voltage vacuum circuit breakers ine lateral inoshanda sisitimu yekumisikidza yemukati inoratidzira yakaparadzana danda rekuvaka.Danda rega rega rinochengeta vacuum interrupter iyo yakavharirwa muresin kana silinda inoumbwa nekuda kwemaitiro akakosha ekugadzira.Iyi nzira yekuvaka inodzivirira vacuum interrupter kubva mukuvhunduka, kusvibiswa uye condensation.
VCB VS1 12kV 630A Indoor High-voltage Vacuum Circuit Breaker:
Interphase kureba: 210mm
Chingoro chemaoko
Double spring operating mechanism
Inoshanda nzvimbo: (kunyanya kunzvimbo dzinoda kushanda kazhinji)
1.the magetsi ekushandisa kutonga uye kudzivirira muindasitiri.
2.mabhizinesi emigodhi.
3.simba zvinomera.
4. substations.
Inogona kugadziridzwa mune switch cabinet kana kuiswa pa handcart.
Kushanda kwakagadzikana uye nyore kuisa.
Vacuum Circuit Breaker Advantages
1.Simple structure.
2.Adapt ultra low resistance type vacuum interrupter.
3.Adapt optimization uye modular spring operating mechanism.
4.Inokodzera zviitiko nekushanda kazhinji.
5.Kuchengetedza kusununguka uye hupenyu hurefu hwebasa.
6.High yakavimbika kushanda.
