Outdoor live tank AC high-voltage load switch is a three-phase outdoor high-voltage equipment with rated voltage of 12KV and rated frequency of 50Hz.
General:
The live tank is used to divide the load current and close the short-circuit current in urban and rural overhead distribution network, and can also break the no-load current of the transformer and the cable charging current at a certain distance.
Service Environment
Ambient air temperature: -40℃ ~ +50℃;
Altitude: no more than 3000m;
The surrounding air can be polluted by dust, smoke, corrosive gas, steam or salt spray, pollution grade: Ⅳ;
The wind speed does not exceed 34m/s (equivalent to 700Pa on the surface of the cylinder);
Vibration or ground movement from outside switchgear and control equipment is negligible;
The amplitude of electromagnetic interference induced in the secondary system does not exceed 1.10kV.
Key Feature
SF6 (purity 99.99%) as a breaking and insulating medium.
Stainless steel shell, fully enclosed by argon arc welding, with good anti-corrosion properties and sealing properties.
Use low energy storage motors.
It can be used under various external conditions.
Light weight and easy to handle.
Truly maintenance-free.
When the gas pressure is reduced to 0.03 ~ 0.07MPa, the switch can automatically lock.
High strength insulation performance.
Equipped with explosion-proof safety devices
