Vacuum circuit breaker
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. Integrated solid-pole closure of the fluent use of a self-ventilation technology cleverly solved the structure of solid insulation caused by heat dissipation.
Snapped vacuum interrupter, air insulated, with electric spring operating mechanism, allowing breaking the ability strong, high frequency short-circuit breaking, no fire and explosion hazards, easy operation is an excellent, practical, strong product.
The product structure using three-phase common tank type, casing into the outlet, cabinets dry air, electric spring mechanism is disposed on the side of the box, can be used under relatively harsh environmental conditions.
This product is vacuum interrupter ceramic shell, goblet longitudinal magnetic field electrode structure, copper-chromium contact materials, with excellent breaking and closing short-circuit current capability.
The product is small, light weight, beautiful appearance. Vacuum interrupter and insulation support sleeve design compact, pole qualifying conductive silicone rubber outer note, can adapt to harsh weather conditions and environment.
ZW8-12/630-20 high voltage vacuum circuit breaker is a three-phase AC 50/60Hz power system, mainly used for breaking, closing urban areas 10KV grid load current, oad current and short circuit current. But also for sub-switch rural power grids and small power system, is urban and rural network of non-oil replacements.
