SF6The excellent properties of gases have led to their ever dominance in the electrical sector. About 10000 tons of SF are available each year6Gas (es)The additive is used in the power industry and accounts for about 80 percent of the total usage amount of the additive. However, due to SF6The atmospheric life of the gas is up to 3200 years, and the gas has strong infrared ray absorption capacity, so the gas has extremely high Global Warming Potential (GWP), which is about CO223900 times of the total amount of the additive is one of the important factors causing global warming. Furthermore, SF6The decomposition of the gas by the discharge produces large amounts of toxic, low-fluoride, such as SF4、S2F10And the like, seriously threatens the health of people. In 1997, the book of Kyoto protocol has specifically recognized SF6The gas is one of 6 kinds of gas which is used in the world in a limited way, and developed countries are required to freeze the emission of greenhouse gases to the level of 90 years in the 20 th century first, and the SF is required to be basically limited by 20206The use of a gas. To reduce or even eliminate SF6Use of gas, SF in recent years6The gas substitution technique becomes one of the research hotspots of experts and scholars at home and abroad, so the SF is treated6The search and research of the alternative gas is imperative.
Therefore, an SF-free composition was developed6The gas insulation ring main unit is very necessary.
