| 摘 要： | 绝缘结构的完整性对于风力发电机长期可靠运行具有重要意义。基于对大型永磁直驱风力发电机绝缘结构特点的分析,提出了一种在定子嵌线过程对定子铁心槽口进行密封的工艺方法,以保证绝缘处理过程铁心槽内的浸渍漆(即浸渍树脂)的填充效果。应用该工艺方法制作的产品铁心槽内结构间隙浸渍漆填充饱满,绝缘电阻、介质损耗、击穿电压等各项电气数据均比原结构有明显提升。该工艺方法的推广应用可以有效保证大型永磁直驱风力发电机定子绝缘结构的完整性和可靠性。

| Abstract: | The integrity of insulation structure was of great importance for the longterm reliable operation of windgenerator. Based on the analysis of the structural features of largesize directdrive permanentmagnet windgenerator, a new operation process of sealing the iron core slot during stator winding inserting course was put forward to improve the filling effect of insulating resin. The iron core slot of the product made by this process was full filled by insulating resin. Test data such as insulation resistance, dielectric loss factor and breakdown voltage were improved obviously compared with those of the original structure. The results indicate that integrity and reliability of insulating structure are assured effectively with the sealing process. |
