当液体绝缘材料中存在气泡时，击穿电压会降低。因此，气泡通常是液体绝缘材料的弱点。近年来，微细气泡在各个领域得到了研究。具有微小气泡的液体绝缘材料有望带来新的性能。在本文中，我们研究了有和没有细小气泡的矿物油的交流击穿电压特性。其结果，确认了微细气泡不易降低矿物油的击穿电压。此外，还证实本文使用的微小气泡发生器具有在超纯水中产生微小气泡的能力。 N2细气泡可能很难像大气泡一样成为弱点。
When bubbles are present in liquid insulating material, breakdown voltage decreases. For this reason, bubbles are weak point for liquid insulating material generally. In recent years, fine bubbles have been studied in various fields. It is expected that liquid insulating material with fine bubbles leads to new properties. In this paper, we investigated the AC breakdown voltage characteristics of mineral oil with and without fine bubbles. As a result, it was confirmed that fine bubbles are less likely to lower the breakdown voltage of mineral oil. In addition, it was confirmed that the fine bubble generator used in this paper has the ability to generate fine bubbles in ultra-pure water. N2 fine bubbles might be difficult to become a weak point like large bubbles.
