| 摘 要： | 植物绝缘油是一种闪点高、环保型的液体电介质,是矿物绝缘油优良的替代品.试验采用转基因菜籽油、转基因花生油和棉籽油等3种基础植物油制取植物绝缘油,研究了植物绝缘油制取方法,深入分析了植物绝缘油的物理、化学性能以及工频击穿电压、介损、介电常数、体积电阻率等电气性能.通过对油品的各项性能指标进行比较,认为三种植物绝缘油中单不饱和脂肪酸支链含量最高的菜籽绝缘油的综合性能最佳.

| Abstract: | Three types of vegetable oil, transgenic rapeseed oil, transgenic peanut oil and cotton-seed oil, are used as raw materials in experiments to obtain the refined insulating oil. The dosage of reagent in experiments is studied for vegetable insulating oil refinement. Furthermore, basic physical and chemical properties of the three types of vegetable insulating oil are analyzed. The electrical properties including breakdown voltage, dissipation factor, dielectric constant, and volume resistance are studied and presented. By compared with each item of properties of the three types of vegetable insulating oil, rapeseed-oil-based insulating oil is considered to possess the best properties due to the fact that it is more abundant of mono-unsaturated fatty acid than the other two types of insulating oil. |
