AC breakdown characteristics of ultra violet curable epoxy resin with nitrogen fine bubbles
We investigated AC breakdown characteristics of ultra violet curable epoxy resin (UV-EP) with nitrogen fine bubbles (FBs) in order to improve insulating properties of UV-EP. As a result, it was found that self-made FB generator mainly add FBs with a diameter between 60 and 150 nm to FB-EP before curing. In addition, SEM images revealed that FB-EP has FBs after curing. Bubble diameter in FB-EP after curing was estimated between 55 and 140 nm due to resin shrinkage. Furthermore, partial discharge inception voltage and electric strength of FB-EP with FB addition for 10 min were almost the same as No FB-EP.
