I-China VD4 series vacuum vacuum-breakers zizixhobo zofakelo lwangaphakathi lwe-switchgear.Nceda uqhagamshelane ne-ROCKWILL ngeemfuno ezizodwa zofakelo.I-VD4-R yoluhlu oluphakathi lwezaphuli zesekethe zesivacuum zombane ezinendlela yokusebenza esecaleni yofakelo lwangaphakathi lubonisa ubuchule bokwakha ipali eyahlukileyo.Ipali nganye igcina isiphazamisi sevacuum esibiyelwe kwiresin xa isilinda sibunjwa ngenxa yenkqubo ekhethekileyo yokwenziwa.Le ndlela yokwakha ikhusela isiphazamisi sevacuum ekothukeni, kungcoliseko kunye nokuxinana.
VCB VS1 12kV 630A Indoor High-voltage Vacuum Circuit Breaker:
Umgama we-Interphase: 210mm
Uhlobo lwenqwelo ephathwayo
Indlela yokusebenza yasentlakohlaza kabini
Indawo esebenzayo: (ingakumbi kwiindawo ezifuna ukusebenza rhoqo)
1.ulawulo lwezixhobo zombane kunye nokhuseleko kwimizi-mveliso.
2.amashishini emigodi.
3.izityalo zamandla.
4.izitishi.
Inokulungiswa kwikhabhinethi yokutshintsha okanye ifakwe kwi-handcart.
Ukusebenza okuzinzileyo kunye nokufakwa lula.
Vacuum Circuit Breaker Advantages
1.Isakhiwo esilula.
2.Adapt isiphazamisi se-vacuum ephezulu esezantsi.
