摘要
在高温条件下研究不同浓度铜、铁微纳米粒子对菜籽油、PFAE油以及FR3大豆油3种不同植物绝缘油工频击穿电压的影响规律。结果表明:植物绝缘油的工频击穿电压随着铜、铁颗粒浓度增大而逐渐降低,且与微纳米粒子颗粒浓度的对数近似呈线性关系。菜籽绝缘油的工频击穿电压下降速度低于PFAE油和FR3大豆油,含铜微纳米粒子绝缘油的击穿电压下降速度显著快于含铁微纳米粒子绝缘油。
The effects of different concentrations of copper and iron micro and nano particles on the power frequency breakdown voltages of three different vegetable insulating oils,namely canola oil,PFAE oil,and FR3 soybean oil,were studied under high temperature conditions.The results show that the breakdown voltage of vegetable insulating oils decreases gradually with the increase of copper and iron particle concentration,and is linearly with the logarithm of micro and nano particles concentration.The breakdown voltage decrease rate of canola oil is less than that of PFAE oil and FR3 soybean oil.The breakdown voltage decrease rate of insulating oil containing copper micro and nano particles is significantly faster than that of insulating oil containing iron micro and nano particles.
