风力发电作为一种可再生能源得到了广泛的应用。风力发电机的叶片可能会被雷击损坏，一般认为叶片的损坏是由于雷击叶片绝缘材料后叶片内部的空气膨胀造成的。为了研究闪电等放电穿过绝缘子路径的现象，我们拍摄了空气放电的传播过程。这种放电在放电路径中通过纸和聚对苯二甲酸乙二醇酯薄膜的多个障碍物传播。结果表明，第一，电极间势垒的存在使统计时滞缩短，而势垒的存在使形成时滞变长。认为势垒抑制了空间电荷的扩散。其次，假设由于先导放电尖端的高电场，绝缘体发生了二次电子发射，可以解释放电时滞比无势垒时滞短，因为电子是由这种发射提供的。
Wind power generators are widely used as one of renewable energy. A Blade of a wind power generator may be damaged by a lightning strike and it is thought that a damage of the blade is caused by expansion of the air inside the blade after a lightning penetrate the insulating material of the blade. In this paper, in order to investigate the phenomenon that a discharge such as lightning penetrate an insulator in its path, we photographed the propagation of the air discharge. This discharge propagated through the multiple barriers of papers and polyethylene terephthalate films in the discharge path. As a result, firstly, the statistical time lag shortened with the existence of barriers between the electrodes, and the formation time lag became longer with the barriers. It is considered that the diffusion of space charge was suppressed by the barriers. Secondly, assuming that a secondary electron emission occurs from the insulator due to the high electric field at the tip of the leader discharge, it might be explained that the discharge time lag was shorter than that without barriers because electrons were supplied by this emission.
