摘　　要：植物绝缘油已成功应用于配电变压器中,但尚未在更高等级电力变压器中得到应用。由于植物绝缘油的粘度比传统矿物油的粘度更高,有必要研究植物绝缘油在厚纸板中的浸渍特性。在分析油纸绝缘浸渍机理的基础上,设计菜籽绝缘油油纸绝缘浸渍试验模型,讨论影响油纸绝缘浸渍过程的主要因素,通过试验得到菜籽绝缘油油纸绝缘浸渍长度随时间的关系曲线,并与矿物油纸绝缘浸渍长度与时间的实测曲线和理论计算曲线进行对比分析。研究结果表明,通过提高浸渍温度,植物绝缘油油纸绝缘的浸渍效果可以达到矿物绝缘油的标准。Vegetable insulating oils have been successfully applied in distribution transformers, but not applied in power transformers with higher voltage levels. Due to the fact that the viscosity of vegetable insulating oil is greater than that of mineral insulating oil, it is necessary to investigate the impregnation characteristics of vegetable insulating oil in transformer boards. The test model of rapeseecl insulating oil-paper insulation impregnation was designed and the impact of oil-paper insulation impregnated with the process of the main factors was discussed based on the analysis of impregnation mechanism of oil-paper insulation. The impregnation characteristics of rapeseed insulating oil were obtained by testing and compared with that of mineral insulating oil. The results show that rapeseed insulating oil-paper insulation impregnated can reach the standards of mineral insulating oil by increasing ＇the impregnation temperature.
