33kv Outdoor Circuit Breaker

Introduction:

The 33kV outdoor vacuum circuit breaker is a compact solution for substations. Integrated unit with CB, CT, PT and protection, suitable for outdoor installation, for breaking, making load current, overload current and short circuit current.

33kv outdoor circuit breaker provides OH conductor or cable termination device, equipped with vacuum circuit breaker, effectively reduces maintenance and improves reliability, very suitable for renewable energy power generation applications.

 

The main function:

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.

 

Specification:

Rated voltage(KV)	40.5KV
Rated current(A)	1250A
