Abstract :
Because of its possible harmful environmental effects, there has been a trend in the last few years to replace SF6 to another, environment friendly insulation gas in gas insulated switchgears. One of the favored candidates is pressurized air. Several researchers have studied and compared the electrical properties of the two gases. However, by changing the insulating medium, the heat transfer performance also changes in the equipment. This paper investigates the influence of the replacement of SF6 to air on the temperature rise of a high voltage gas insulated switchgear by means of 2D multi-physics finite element analyses.
