Description
technical field [0001] The invention relates to the technical field of gas insulation materials for electrical equipment, in particular to a temperature-controllable gas insulation performance test system and a method thereof. Background technique [0002] SF 6 It is a strong electronegative gas and has been widely used in electrical equipment such as gas-insulated combined electrical appliances (GIS) as an insulation and arc extinguishing medium. However SF 6 It is a greenhouse gas whose greenhouse effect coefficient (GWP) is CO 2 23900 times of , which means that every 1kgSF emitted into the atmosphere 6 The greenhouse effect caused by the gas is equivalent to the emission of 23.5t CO 2 gas; and SF 6 The gas is extremely difficult to degrade in the atmosphere, with a lifespan of about 3,200 years, and has a cumulative effect on global warming. In consideration of environmental protection, the parties to the United Nations Convention on Climate Change signed the "Kyot...
