空冷汽轮发电机定子整浸VPI国产材料应用研究

Domestic Insulation Materials in the VPI of Air-cooled Turbogenerator Stator Vacuum Pressure Impregnating

介绍了采用国产材料进行空冷发电机定子整浸研发试验过程,详细分析了试验数据,最后阐明国产纯环氧酸酐树脂和少胶带用于空冷发电机定子整浸是可行的,但与环氧酸酐树脂配套的绝缘材料选择和整浸绝缘工艺还需进一步试验摸索.

This paper introduces the VPI test of air-cooled turbogenerator stator with domestic materials and analyses these test data. The results indicate that it is technically feasible to use a domestic purity ep-oxy-anhydride resin and mica tape in the VPI of air-cooled turbogenerator stator. It has been pointed out that the choice of insulated materials suiting the domestic purity epoxy-anhydride resin and the VPI tech- nology needed to be further studied.
