得る改良された電気絶縁油に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved electrical insulating oil that can be used in various oil-immersed electrical equipment such as oil-immersed transformers, oil-immersed switches, oil-immersed power cables, and oil-immersed condensers. .

望まれている。In recent years, oil-immersed transformers, oil-immersed switches, oil-immersed cables,
For oil-immersed electrical equipment such as oil-immersed capacitors, flame-retardant electrical insulating oil is desired from the viewpoint of disaster prevention.

絶縁油が提案されている。Mineral oil,
Electrical insulating oils have been proposed in which a base insulating oil is a hydrocarbon insulating oil such as alkylbenzene or polybutene, or a mixture of two or more thereof, and a phosphate phosphate ester is mixed therein.

ン酸エステルの方が破壊電圧が低い事からこの混合油の

なってしまうという問題があった。However, insulating oils made of mineral oil and/or hydrocarbon oil as a base insulating oil mixed with phosphate phosphate esters are not completely compatible due to differences in molecular structure and specific gravity. There is a problem of separation, and since phosphate phosphate esters have a lower breakdown voltage than mineral oils and hydrocarbon oils, the breakdown voltage strength of this mixed oil is equivalent to that of phosphate phosphate esters. There was a problem with this.
本発明はかかる点に着目し、これを改善すべく鋭意研究

明を達成したものである。The present invention has focused on this point, and as a result of conducting intensive research to improve it, we have developed a base insulating oil that uses mineral oil, alkylbenzene, polybutene, and other hydrocarbon oils alone or as a mixture of two or more of them. 0.01-1.
The present invention was achieved by discovering that by mixing OVol'% of a nonionic surfactant, a flame-retardant electrical insulation material with significantly improved breakdown voltage characteristics compared to conventional products can be obtained.

うになるためである。In the present invention, the amount of nonionic surfactant mixed into the base insulating oil is 001 to 0.
The reason why it is limited to 1% I Vol. This is because it is thin, and the reason why the upper limit is set to 10 Voi% is that it is 1.0 Voi%.
If the amount exceeds 1%, the compatibility between the two will improve, but the surfactant will act as an impurity, and the breakdown voltage characteristics of the resulting mixed insulating oil will deteriorate. It is.
