Description

technical field [0001] The invention belongs to the field of high-voltage insulation technology and environmental protection, and specifically relates to a method for researching dielectric barrier discharge and efficiently treating sulfur hexafluoride gas (SF 6 ) experimental system and experimental method. Background technique [0002] Sulfur hexafluoride (SF 6 ) has good electrical properties and excellent arc extinguishing performance, and is widely used in various high-voltage electrical equipment as an insulating dielectric material. Furthermore, since SF 6 It is a colorless, odorless, non-toxic, non-flammable and non-corrosive inert gas. It is also widely used in metal smelting, aerospace, medical, chemical, atmospheric tracer and electronic manufacturing industries. SF produced in these industries 6 If it is directly discharged into the atmosphere without treatment, it will have a great impact on the environment. Studies have shown that SF 6 The potential value...
