Product Description

General

Outdoor high-voltage AC isolation switch (hereinafter referred to as the "isolation switch"), for rated frequency 50 Hz outdoor high-voltage switchgear, for 1 0kV high-voltage lines in the case of voltage and no load to change. And the maintenance of high-voltage bus, circuit breaker and other electrical equipment and live high-voltage line for electrical isolation, can also be used for splitting small capacitive current and inductive current.The isolation switch complies with GB 1985-2014 "High voltage AC isolation switch and ground switch", DL/T 486-2010 "High voltage AC isolation switch and ground switch" and other technical standards.

Service environment

     

  • Altitude: not more than 1000m, if the altitude is higher than 1000m, the rated insulation level should be corrected accordingly;

  • Ambient temperature: upper limit +40ºC, lower limit -40ºC, the average temperature of the hottest month 30ºC, the maximum daily temperature difference 25K;

  • Solar radiation intensity (outdoor) : 0.1W/cm2;

  • Wind speed/wind pressure (outdoor) : 34m/s (700Pa);

  • Pollution grade: e;

  • Ice thickness: ≤20mm;

  • Humidity: average daily relative humidity ≤95%, average monthly relative humidity ≤90%;

  • Earthquake resistance: horizontal acceleration 0.3m /s2, vertical acceleration 0.15m /s2;

  • Safety factor: sinusoidal resonance three cycles, safety factor above 1.67

Key Feayure

 
  • Isolating switch with double column, contact into open type structure, has the ability of self cleaning contact, improve the contact reliability;

  • Finger made of new material with high strength, high conductivity, high elastic. Relying on the elastic contact finger clamping itself, to avoid the spring corrosion, contact clamping fever caused by annealing

  • Force to reduce the contact resistance increases, the contact heat intensified the vicious spiral.

  • The rotating part according to the design requirements of the isolating switch maintenance free. The rotating seat designed seal structure,moisture, dust and harmful gas can not enter, bearing, molybdenum disulfide lithium base grease will never work in

  • A good environment, bearing, never rust, grease can not be lost, never dry up, the isolation switch operating torque will increase after long term operation. Stainless steel shaft and oil-free self-lubricating bearing

  • With the structure of steel by hot dip galvanizing, ensure the isolation switch operation is flexible, portable and reliable, never rust.
