Product Description

General

 

Outdoor high-voltage AC isolation switch (hereinafter referred to as "isolation switch") is an outdoor high-voltage switch with a rated frequency of 50Hz, which is used for the replacement of 35kV high-voltage lines under the condition of voltage and no load, and for the electrical isolation of high-voltage bus bars, circuit breakers and other electrical equipment to be repaired and live high-voltage lines. It can also be used to split small capacitive and inductive currents.

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 +45ºC, 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 Feature

 
  • The isolation switch is composed of a base, an insulating pillar, a conductive part and an operating mechanism

  • The isolation switch is a single-pole type, and the three poles can also be connected into a three-pole type that can be linked through a connecting rod

  • With CS11 or CS8~6D manual mechanism operation

  • The two switch has reasonable structure and flexible operation
