意味し、そのため高電圧下でも良好な電気特性を示しか
つ高い耐久性を有する電気絶縁油が求められている。Electrical equipment that uses electrical insulating oil includes capacitors, transformers, retractors, cables, etc. In recent years, as electrical equipment has become more complex, these electrical equipment have been required to operate at higher voltages. Demand for miniaturization of these devices is also becoming stronger. This means that a high electrical stress is applied to the electrical insulating oil used, and therefore there is a demand for an electrical insulating oil that exhibits good electrical properties even under high voltage and has high durability.

動電圧の高圧化の要請に十分に対応できないという問題
がある。However, since these polysiloxanes do not have a very high dielectric constant, they cannot necessarily satisfy the above-mentioned demand for miniaturization of electrical equipment, and their corona resistance properties such as corona generation potential are not comparable to mineral oil-based insulating oils. Therefore, there is a problem that it cannot fully meet the demand for higher operating voltages.

It is 30 mol%. When the proportion of phenyl groups is less than 2 mol%, ('
The compatibility with component b), the halogenated phthalate ester, becomes poor, making it difficult to obtain a uniform composition. Moreover, if it exceeds 30 mol%, it is not possible to economically obtain a siloxane with a desired viscosity. The methylphenyl silicone preferably has a viscosity (at 25° C.) of 130 cs or less, particularly preferably in the range of 10 to 100 cs. If the viscosity of the methylphenyl silicone exceeds 130 cs, it may be difficult to adjust the viscosity of the composition to a range of 10 to 500 cs, which will be described later, and this tends to cause problems in loading into electrical equipment, etc. The viscosity of this methylphenyl silicone is preferably as low as possible from the viewpoint of solubility of the components, but if it is less than 10 cs, the flame retardance of the resulting composition tends to decrease, so it is preferably 10 cs or more.

Impregnation operations become difficult, air bubbles may be trapped in the oil, and problems such as a decrease in cooling effectiveness occur due to low heat transfer.

実施例３
上述の誘電流体を用い、下記のようにして変圧器を作製
し、特性を評価した。結果を表４に示す。Example 3 Using the dielectric current described above, a transformer was manufactured in the following manner, and its characteristics were evaluated. The results are shown in Table 4.
３相６０Ｈｚ ５００ＫＶＡ絶縁階級６号の油入変圧器
として、クラフト紙被覆電線を巻回したコイルに鉄心を
挿入してなる変圧器で相間にプレスポードバリヤーを設
けた。A 3-phase 60Hz 500KVA insulation class No. 6 oil-immersed transformer was constructed by inserting an iron core into a coil wound with kraft paper-coated wire, and a presspod barrier was provided between the phases.
上記変圧器を加熱、減圧乾燥後、絶縁油を含浸して変圧
器とした。The above transformer was heated, dried under reduced pressure, and then impregnated with insulating oil to form a transformer.
本発明に用いられる電気絶縁油は、良好な耐熱性、燃焼
抵抗性、安全性、電気特性を有するものであり、特に高
電圧下においても耐コロナ特性はかの電気特性が良好で
あるので、本発明の電気機器は高電圧下における作動に
適するものである。The electrical insulating oil used in the present invention has good heat resistance, combustion resistance, safety, and electrical properties, and in particular has good corona resistance and electrical properties even under high voltage. The electrical equipment of the present invention is suitable for operation under high voltage.
さらに、前記電気絶縁油は誘電率、が大きいとの特徴も
有するものであるため、本発明の電気機器は小型化に対
応し得るものである。Furthermore, since the electrical insulating oil is characterized by a high dielectric constant, the electrical equipment of the present invention can be adapted to miniaturization.
