High-voltage disconnector ZGW6-816/J6300-25

DC

ZGW6-816/J6300-25 high voltage DC disconnector(ZGW6-816 disconnector in short) is installed at ± 800 kV converter station on the polar side of DC field and high voltage side of DC filter, used for circuit switch under the condition of no load flow, to make the electrical isolation between the high voltage and high voltage busbar, converter valve, flat wave reactor and other electrical equipments which are in the maintenance, to provide a qualified, safe and visible insulation distance. working conditions to the maintenance equipment and maintenance staff . The disconnector which is installed on the high voltage side of DC filter has the ability of opening and closing the harmonic current. Service environment a) The surrounding air temperature: -40℃～+40℃ b) Altitude: ≤1000m c) Wind speed: ≤34m/s d) Icing-thickness: ≤10mm f) Anti-seismic ability: AG3 g) The installation site should be free of severe vibration and flammable, explosive materials and chemical corrosion.
