Zw8 Series Outdoor High Voltage AC Intelligent Load Break Switch Vacuum Circuit Breaker Manufacturers Auto Recloser

GENERAL
 
ZW8-12 (G) series outdoor high-voltage AC intelligent vacuum circuit breaker (hereinafter referred to as "circuit breaker only") is applicable to the three-phase power system with three-phase AC 50Hz and voltage of 12kV. It is used for breaking and closing load currents. It has overload and short-circuit protection, definite time-delay protection, and an automatic reclosing function, and can also be equipped with a lightning arrester or isolating switch according to user needs.

The intelligent circuit breaker meets the requirements of GB / T 1984-2014 high voltage AC circuit breaker, DL / T 402-2016 high voltage AC circuit breaker, and DL / T 403-2000 technical conditions for ordering 12kV ~ 40.5kV high voltage vacuum circuit breaker and DL / T 721-2013 remote terminal of the distribution automation system.

MODEL DESCRIPTION

USAGE: ENVIRONMENTAL CONDITION
  1. Altitude:  1000m, If the altitude is higher than 1000m, the rated insulation level shall be corrected accordingly.
  2. Ambient temperature: -40oC ~ +45oC, 
  3. Maximum daily temperature difference: 25K 
  4. Humidity: Average daily relative humidity: 95%, average monthly relative humidity: 90%. 
  5. Sunshine intensity: not more than 0.1W/cm2 
  6. Wind Speed:  34m/s 
  7. Wind pressure: 700Pa
  8. Pollution level: e - level
  9. Icing thickness: Not more than 10mm 
  10. Resistance to floor drain: horizontal acceleration 0.3g, vertical acceleration 0.2g
MAIN ADVANTAGES

☆ Ceramic vacuum arc extinguishing chamber is adopted, with strong arc extinguishing ability and short-circuit breaking ability;
☆ It has the advantages of being explosion-proof, anti-condensation, anti-pollution, and no environmental impact
☆Air silicone rubber and engineering plastic composite insulation are adopted to avoid the possibility of insulation accidents caused by oil deterioration in oil insulation;
☆ The body can be equipped with an isolating switch to form a "combined electrical apparatus" with obvious fracture. The user can choose to use a silicone rubber insulating sheath on the isolating switch. The sheath has the advantages of rain, snow, sand, and strong resistance to pollution and corrosion, which can effectively improve the anti-freezing and anti-oxidation ability of the isolating switch;
☆ It can realize three-stage protection, zero sequence grounding protection, reclosing, and remote communication.
