    • PROBLEM TO BE SOLVED: To provide an oil-filled electric apparatus using a vegetable oil, capable of reducing the environmental load, as an insulation oil.SOLUTION: Out of vegetable oils, a vegetable oil containing a lot of natural antioxidant is used as an insulation oil. For example, rice oil containing a lot of tocotrienol or orizanol is preferable. Since oxidation stability of insulation oil can be ensured by the natural antioxidant contained in vegetable oil, it is not required to add an antioxidant having uncertain impact on the environment to the insulation oil. Even a vegetable oil not containing a lot of natural antioxidant enhances oxidation stability without having adverse effect on the environment, when adding an antioxidant that has been approved to be used in foods. The oil-filled electric apparatus has high possibility to be utilized in a transformer or a cable, a circuit breaker, or a capacitor.
    • 要解决的问题:提供一种使用能够降低环境负荷的植物油的充油电气设备作为绝缘油。解决方案:在植物油中,含有大量天然抗氧化剂的植物油被用作 绝缘油。 例如,优选含有大量生育三烯酚或orizanol的米油。 由于绝缘油的氧化稳定性可以通过植物油中所含的天然抗氧化剂来确保,因此不需要向绝缘油添加对环境具有不确定影响的抗氧化剂。 即使是不含大量天然抗氧化剂的植物油,当加入已被批准用于食品的抗氧化剂时,也能增强氧化稳定性,而不会对环境产生不利影响。 充油电器在变压器或电缆,断路器或电容器中具有很高的可能性。

    • PROBLEM TO BE SOLVED: To provide a lubricant composition causing little oxidation deteriorating even in high-temperature conditions, and a rolling apparatus having a long service life in the high-temperature conditions.
      SOLUTION: The deep groove ball bearing includes: an inner ring 1 having a raceway 1a on the outer circumference surface; an outer ring 2 which has a raceway 2a facing the raceway 1a in the inner circumference surface and is disposed in the radial direction outside of the inner ring 1; a plurality of rolling elements 3 freely rotatably arranged between the both raceways 1a and 2a; a holder 4 holding a plurality of rolling elements 3 between the inner ring 1 and the outer ring 2; and sealing devices 5 and 5 covering the opening of a clearance between the inner ring 1 and outer ring 2. Inside a clearance part formed between the inner ring 1 and outer ring 2 to house the rolling elements 3, a grease type lubricant composition G lubricating between the raceways 1a and 2a and the rolling elements 3 is disposed. The lubricant composition G comprises a base oil, a thickener, an anti-oxidant, and a coenzyme Q.
