Products Description


VS1 vacuum circuit breaker with spring mechanism details listed as belows:
1.Ambient temperature: not higher than +40 °C, not less than -40°C
2. Altitude: not exceed 2000m.
3. Relative humidity: daily average of not more than 95%, month average of not more than 90%.
saturated vapor pressure daily average of not more than 2.2 × 103MPa, month average not more than 1.8 × 103MPa.
4. Earthquake intensity: not more than eight.
5. No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration.
Adopt solid insulation structure, use of advanced solid epoxy sealing technology, the first time, the vacuum interrupter. A
leading electrical circuit. insulation and other support to become an integrated combination of solid seal pole. Successfully from
a fundamental solution of the vacuum breaker gas environment, tolerance issues, make it more broad. Integrated solid-pole closure
of the fluent use of a self-ventilation technology, cleverly solved the structure of solid insulation caused by heat dissipation.
Advantages
Simple structure
Adapt ultra low resistance type vacuum interrupter
Adapt optimization and modular spring operating mechanism
Suitable for occasions with frequent operation
Free maintenance and long service life
High reliable performance
