摘　　要：采用JF5440-1G高机械强度多胶粉云母带制备了高压电机模拟线棒,研究了线棒主绝缘的介质损耗、介质损耗增量、电气强度、电寿命、导热系数、力学性能和耐冷热循环等性能,并与桐马主绝缘进行了比较。结果表明:高机械强度多胶粉云母带模拟线棒主绝缘的介电性能与桐马绝缘相当,导热系数、力学性能和耐冷热循环等性能优于桐马主绝缘。High-voltage electrical machine model stator bars were prepared by using JF5440-1G high mechanical strength resin-rich tapes. The dielectric loss, dielectric loss increment, breakdown strength, electrical endurance, thermal conductivity, mechanical properties, and resistance to cold and hot cycle of the main insulation of the bars were investigated and compared with the tung oil-maleic imide main insulation. The results show that the dielectric properties of the high mechanical strength main insulation are as good as that of the tung oil-maleic imide main insulation, and its thermal conductivity, mechanical properties, and resistance to cold and hot cycle are better than of the tung oil-maleic imide main insulation.
