スが油に吸収されるか否かを調べて評価される。DETAILED DESCRIPTION OF THE INVENTION This invention applies to field-stable (that is, gas-absorbing) capacitors, etc., in which mineral oil-based electrical insulating oil is a complex mixture of hydrocarbon molecules, and its chemical components can be broadly classified into aromatic, It can be represented as olefinic, naphthenic and paraffinic molecules. Among these components, the content of aromatics and olefins having unsaturated bonds serves as a guideline for determining gas absorbency and vinegar value. Gas absorbency is evaluated by sealing oil and hydrogen gas in a sealed container, causing a discharge to occur at the oil/gas interface, and examining whether hydrogen gas in the gas phase is absorbed by the oil.

、放電エネルギーによって不飽和結合が切断され水添反
応が進むため、気相中の水素ガスは消費され、ガス吸収
性を示す。Insulating oil with a high content of aromatic and olefin components, unsaturated bonds are broken by discharge energy and the hydrogenation reaction progresses, so hydrogen gas in the gas phase is consumed and exhibits gas absorption properties.

のの混合油の不燃性すなわち引火点を高くする点におい
ては改善されない。However, since each base oil has an optimum degree of refinement from the viewpoint of oxidation stability, it is difficult to increase the content of only specific components. Therefore, if the refined insulating oil has poor gas absorption properties, synthetic oils such as alkylbenzene or alkylnaphthalene, which have excellent gas absorption properties, may be mixed in to improve the properties. However, although it improves gas absorption, it does not improve the nonflammability of the mixed oil, that is, raise the flash point.
本発明の特徴は、上記のような合成油に替って植物性の
なたね油を鉱物系油と混合することにより、ガス吸収性
及び不燃性を共に改良したこと忙ある。A feature of the present invention is that both gas absorption and nonflammability are improved by mixing vegetable rapeseed oil with mineral oil instead of the synthetic oil as described above.
本発明は鉱物系油と植物性のなたね油とを混合してなる
混合油を電気絶縁油として使用した油入電気機器♂辱る
。The present invention uses oil-filled electrical equipment that uses a mixed oil of mineral oil and vegetable rapeseed oil as an electrical insulating oil.
次に本発明を１図に基づき説明する。なたね油はオレイ

などの鎖状不飽和炭化水素分子を多く含有しているので
ガス吸収性はすぐれている。Next, the present invention will be explained based on FIG. Rapeseed oil has excellent gas absorption properties because it contains a large amount of chain unsaturated hydrocarbon molecules such as oleic acid, linoleic acid, lylunic acid, eicosenoic acid, and erucic acid.

ぐれていることがわかる。Figure 1 shows the gas absorption properties of various insulating oils, and it can be seen that the gas absorption properties of rapeseed oil are extremely superior to those of ordinary mineral-based insulating oils.

必要なガス吸収性を達成する実効量により決められ、上
限はなたね油の価格が鉱油の価格より高価であるため、
その価格を考慮して決めらねる。Refined rapeseed oil has general electrical properties at a practical level and is highly compatible with ordinary mineral-based P-rim oils, so it can be mixed with mineral-based insulating oils as a gas absorption improver. can. Figure 1 shows the gas absorption of a mixed oil of mineral oil and rapeseed oil, and it can be seen that by mixing rapeseed oil, the gas absorption of mineral oil is improved in proportion to the mixing ratio. . The lower limit of the mixture ratio of rapeseed oil is determined by the effective amount to achieve the required gas absorption, and the upper limit is determined by the fact that the price of rapeseed oil is more expensive than that of mineral oil.
I can't decide considering the price.
また、鉱物系油並びにアルキルベンゼン及びアルキルナ
フタレンのり１火点はおよそ１３θ〜／に００Ｃである
のに対し、なたね油は約３０θ℃である。Further, the fire point of mineral oil, alkylbenzene, and alkylnaphthalene paste is about 13θ to 00C, while rapeseed oil is about 30θC.
従ってなたね油の混合割合に対応し混合油の引火点が上
昇することとなる。Therefore, the flash point of the mixed oil increases in accordance with the mixing ratio of rapeseed oil.

。As mentioned above, the mixed oil of mineral oil and rapeseed oil based on this invention has good gas absorption properties and can be used as an insulating oil with a high flash point, so it can be applied to oil-filled electrical equipment with good electric field stability. - Also, rapeseed oil is used as an edible oil.
Needless to say, it is an extremely safe substance from a sanitary standpoint.
