Abstract

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.

含氮微气泡的紫外线固化环氧树脂的交流击穿特性

为了改善紫外线固化环氧树脂（UV-EP）的绝缘性能，我们研究了加入氮气微泡（FBs）的紫外线固化环氧树脂（UV-EP）的交流击穿特性。结果发现，自制 FB 生成器主要是在固化前向 FB-EP 中添加直径在 60 至 150 nm 之间的 FB。此外，扫描电镜图像显示，固化后的 FB-EP 中含有 FB。由于树脂收缩，固化后 FB-EP 中的气泡直径估计在 55 至 140 nm 之间。此外，添加了 FB 的 FB-EP 在 10 分钟内的局部放电起始电压和电强度与未添加 FB 的 FB-EP 几乎相同。
