Abstract
Sulfur hexafluoride (SF6) gas is widely used as a gas insulation medium in medium and high voltage arc extinguishing or insulated electrical equipment, but the gas is a serious greenhouse effect gas and poses a great threat to the environment. This paper introduces a new environmentally friendly insulating gas of hexafluoropropylene (1-C3F6) with the liquefaction temperature of -29.4°C and the global warming potential (GWP) equivalent to CO2, and especially investigates its saturation vapor pressure characteristics and insulation performance. Under different electrode structures and voltage characteristics, the insulation characteristics of the 1-C3F6/CO2 gas mixture were studied by changing the electrode distance and the pressure of gas mixture.
