33kv Outdoor Vacuum Circuit Breaker

Outdoor high-voltage vacuum circuit breakers are outdoor high-voltage switching devices with three-phase AC 50Hz and rated voltage of 40.5kv and below. It can be used for dividing and combining load current, overload current and short-circuit current.

Feature

1. Small size, light weight, maintenance-free and long service life.

2. It can be equipped with a circuit breaker, and the breakpoint is obvious.

3. It can be equipped with a controller to realize automatic reclosing, and the reclosing times and reclosing time can be selected arbitrarily. With quick-break protection, the fixed value can be set arbitrarily.

4. Remote control under the lever, electric, manual and other operation methods.

5. It can monitor the circuit running current in real time.

The use environment of outdoor vacuum circuit breakers

1. Ambient temperature: -40℃～40℃, the daily temperature difference does not exceed 20℃

2. Pollution level: no more than level 4

3. Altitude: no more than 2500mm

4. Wind pressure: no more than 700pa

5. Places without fire, explosion and chemical corrosion

6. Infrequent strenuous exercise, and the earthquake intensity does not exceed 8 degrees.
