Temperature Rise Comparison of Switchgear in sf6 gas 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 gaz sf6 as the insulating gas of switchgear on the perspective of temperature rise. Keywords: temperature rise, switchgear, sf 6Get price

Sulfur hexafluoride - Wikipedia

6 is used to provide a tamponade or plug of a retinal hole in retinal detachment repair operations in the form of a gas bubble. It is inert in the vitreous chamber and initially doubles its volume in 36 hours before being absorbed in the blood in 10–14 days. SF 6 is used as a contrast agent for ultrasound imaging. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein.Get price

Why sf6 gas 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
