Description

technical field [0001] The invention relates to the field of electrical technology, in particular to the technical field of mixing insulating medium preparation. Background technique [0002] Gas-insulated equipment is one of the irreplaceable key power transmission and transformation equipment in modern power grids. It has the advantages of compact structure, little influence from environmental factors, and high operational safety and reliability. SF 6 Gas is currently the most widely used insulating medium in the power industry because of its excellent insulating and arc-extinguishing properties. But since SF 6 The gas has a strong greenhouse effect and has been included in the 1997 "Kyoto Protocol" as one of the six restricted greenhouse gases. In addition, the 2016 Paris Agreement also explicitly calls for net-zero greenhouse gas emissions in the second half of this century. Therefore, the development of alternative SF 6 Environmentally friendly gas and the developm...
