摘　　要：该研究以甲基四氢苯酐和双酚A二缩水甘油醚为原料制备EA浸渍漆,然后在EA浸渍漆中加入改性后的纳米SiO_(2),制备EA/mSiO_(2)浸渍漆,并制造模拟线棒。通过对比EA浸渍漆和EA/mSiO_(2)浸渍漆的耐电晕、热稳定性、介质损耗、抗击穿、绝缘老化、热老化寿命等性能,研究高压电机绝缘浸渍漆热老化绝缘性能及提升方法。In this study,methyl tetrahydrophenylanhydride and bisphenol A diglycidyl ether were used as raw materials to prepare EA impregnation paint.Then,modified nano-SiO_(2)was added into EA impregnation paint to prepare EA/mSiO_(2)impregnation paint,and simulated wire rods were manufactured.By comparing the performance of EA impregnation paint and EA/mSiO_(2)impregnation paint on corona resistance,thermal stability,dielectric loss,resistance to wear,insulation aging,thermal aging life,etc.,the thermal aging insulation performance of insulation impregnation paint for high voltage motor and its improvement method are studied.
