The insulating gas Decomposition Mechanism: Background and Significance

Jun 07, 2017 · Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (sf6 gas) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of sf 6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decomposition phenomenon would greatly reduce theGet price
