近年来，微细气泡技术备受关注，其研究在各个领域不断推进。因为人们知道细小的气泡具有与普通大气泡不同的各种特定特征。通常，众所周知，绝缘油中的气泡成为击穿的起点并导致击穿电压降低。然而，细小的气泡可能能够在不降低击穿电压的情况下赋予绝缘油新的特性。本文研究了含有和不含细小气泡的矿物油在氮气气氛下的绝缘性能。另外，测定添加了微细气泡的矿物油的气泡直径。结果，确认了矿物油的击穿电压没有显着降低。此外，发现矿物油中存在直径为200-2000nm的细小气泡。
In recent years, fine bubble technology has attracted attention and its research is advancing in various fields. Because fine bubbles became known to have various specific characteristics different from normal large bubbles. Usually, it is known that bubbles in the insulating oil become a starting point of the breakdown and cause the breakdown voltage decrease. However, fine bubbles may be able to impart new characteristics to the insulating oil without decreasing the breakdown voltage. In this paper, the insulation properties of mineral oil with and without fine bubbles with nitrogen gas were investigated under nitrogen atmosphere. In addition, the bubble diameter of mineral oil with fine bubble added was measured. As a result, it was confirmed that the breakdown voltage of the mineral oil did not decrease significantly. Furthermore, it was found that fine bubbles were present in the mineral oil at a diameter of 200-2000 nm.
