摘　　要：文章利用针-板电极产生的极不均匀场强,对非来源于食物的麻风树植物油和矿物绝缘油在极不均匀场中雷电冲击电压作用下的放电现象进行了研究。研究结果显示,在具有相同峰值的极不均匀正、负雷电冲击电压作用下,麻风树油中的放电形状、放电长度、放电量和放电发展速度均优于或等同于矿物绝缘油,这说明麻风树油可替代矿物绝缘油用于高电压设备的绝缘保护。The lightning shock discharge phenomenon of jatropha curcas oil which was derived from non-food and mineral insulating oil in a very uneven field strength that was produced by the form of needle-plate electrodes were studied. The results were showed that the discharge shape,discharge length, discharge capacity and discharge development speed of jatropha curcas oil in the same peak with the very uneven positive and negative impact voltage were better than or as good as 25# mineral insulating oil, the jatropha oil could be used to replace mineral insulating for high voltage equipment insulation.
