Theoretical study of the chemical decomposition mechanism ...· A quantum chemistry analysis combining density functional theory (DFT) was used to study the complex decomposition process of SF 6.. A decomposition model of SF 6 with two typical zones was established.. SOF 2 and SO 2 are both mainly generated through hydrolysis reaction in the low-energy region.. SO 2 F 2 can be generated from oxidation reaction of SF 2 and hydrolysis reaction of SOF 4, …

Hitachi ABB Power Grids Launches Open and Scalable ...· Hitachi ABB Power Grids has been pioneering transformer technology for over a century, collaborating with global committees in setting technology standards and protocols.

The SF6 Decomposition Mechanism: Background and ...· Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decomposition phenomenon would greatly …
