(English Abstract) |
The experimental and analytical studies have been carried out to identify the breakdown mechanism of mica-epoxy composite materials. After mica-epoxy composite materials are degraded artificially, the breakdown mechanism of insulation is analyzed in air and hydrogen atmosphere by surface analysis EDS and SEM techniques. It can be concluded that the potassium ions of mica are replaced by hydrogen ions at the boundary of mica-epoxy and/or mica-mica. The conductive layers of potassium ions enable high voltage fields or multiple stresses to create voids and microcracks.
