摘要(Abstract)：

风力发电机在遭受雷击时叶片一般处于转动状态,而叶片转动对其雷击接闪特性的影响尚不明确。为探究转动风机的叶片雷击接闪特性,设计了可控转速的1:30缩比2 MW风机模型与适合试验的弧面电极,采用标准负极性操作波,制作了2种类型的叶尖接闪器,开展了1 m间隙时不同转速下的大量接闪试验。试验结果表明,在1 m间隙下,无论叶尖是接闪帽还是接闪盘配置,间隙击穿电压均随着转速的提升而升高,而风机静止时击穿电压会随接闪叶片角度增大而升高。分析认为,叶片旋转会导致叶尖区域积聚的正离子浓度降低,抑制了上行先导的发展,从而提升了击穿电压。根据试验结果推断,在此工况下风机旋转会降低其引雷能力。试验结果对风机的防雷设计具有参考意义。

关键词(KeyWords)： 转动风机;接闪器;缩比试验;接闪特性;间隙放电
