High Voltage Outdoor Vacuum Circuit Breaker ZW7 40.5KV

ZW7-40.5KV Outdoor high voltage Outdoor Vacuum Circuit Breaker

Overview:

ZW7-40.5 outdoor high voltage vacuum circuit breaker is used for AC three-phase power system with 50Hz and voltage of 40.5KV, which is used for breaking, closing load current, overload current and short circuit current.

Main funcion:

1. Vacuum arc extinguishing, strong breaking capacity, long electrical life and 10,000 mechanical life;

2. Simple structure, maintenance-free, long maintenance period;

3. Good insulation performance and strong anti-pollution ability;

4. It can be equipped with spring or electromagnetic operating mechanism, with reliable mechanical performance and frequent operation; no fire and explosion hazard;

5. Built-in current transformer, the lecturer's precision reaches 0.2, which can realize three-phase interactive protection;

6. With condensation controller, it can keep the circuit breaker running reliably under certain temperature and humidity.

Environmental conditions:

1. Ambient air temperature: upper limit +50 ° C, lower limit -30 ° C;

2. Altitude: ≤3000m (If the altitude is to be increased, the rated insulation level will increase accordingly);

3. Wind pressure: no more than 700Pa (equivalent to a wind speed of 34m / s;

4. Amplitude: seismic intensity of 8 degrees;

5. Pollution level: Level III;

6. Large daily temperature difference: no more than 35 °C.
