Abstract Gas insulated metal-included switchgear (GIS) is an important switchgear equipment in the power system. Due to its small size and small heat-dissipation area, overheating problems cannot be ignored. Traditional GIS uses SF₆ gas as insulation and arc extinguishing medium, while SF₆ gas brings serious greenhouse effect. In recent years, GIS research on environmentally friendly gas has received extensive attention. Therefore, research on the thermal properties of environmentally friendly gas GIS is also urgent. In this paper, the thermal characteristics of the 126kV eco-friendly GIS isolating switch with CO₂ as the insulating arc extinguishing gas was studied. The GIS model was subjected to steady-state thermal analysis through the coupling of electric-thermal-airflow field, and the temperature field of GIS was obtained. The distribution was compared with the temperature rise experiment results of GIS to verify the correctness of the thermal analysis model. Subsequently, the model was used to calculate the temperature field of the GIS isolation switch part filled with different gases, and the heat dissipation characteristics of SF₆, CO₂, N₂ and N₂ and C₅F₁₀O mixed gases at different pressures were compared. The results show that the SF₆ gas at the same gas pressure is about 10K lower than the highest temperature of GIS filled with CO₂ and N₂. Mixing 10% C₅F₁₀O in N₂ can reduce the temperature rise of GIS by 4.21K. The research in this paper can provide reference for the application of environmentally friendly gas in GIS.
