Temperature Rise Comparison of Switchgear in gaz sf6 2 and Air

temperature fields in three gases are similar in the switchgear. The temperature rise of current-carrying loop is the highest in Sulfr hexafluoride and is the lowest in the air. So the conclusion could be made that air or N2 can replace Sulfr hexafluoride as the insulating gas of switchgear on the perspective of temperature rise. Keywords: temperature rise, switchgear, gaz sf6Get price

Why Sulfr hexafluoride or Sulfur Hexafluoride gas is better for arc

Cleanliness in assembly is therefore very important for sf 6 using switchgear. Fortunately, during the factory and field power frequency high-voltage tests, contaminating particles can be detected as they move and cause small electric discharges (partial discharge) and acoustic signals—they can then be removed by opening the equipment.Get price
