    • To effectively perform lightning protection in a blade for wind power generation and to prevent the blade from being damaged when arresting lightning. The lightning protection structure of the blade for wind power generation includes a conductive lightning receptor 1 attached to a part of the blade for wind power generation, and a ceramic member 10 interposed between at least surface-layer portions of the lightning receptor 1 and the blade 5. Therefore, an electric field is likely to concentrate at an interface between the ceramic member 10 having excellent heat resistance and the lightning receptor 1, so that it is possible to effectively prevent the blade 5 from being damaged due to a concentration of the electric field at the interface of the blade 5 attached with the lightning receptor 1 when arresting the lightning.
    • 为了有效地执行风力发电的叶片中的防雷保护,并防止在制动闪电时刀片受损。 用于风力发电的叶片的防雷结构包括附接到用于风力发电的叶片的一部分的导电雷电接收器1和插入在雷电接收器1的至少表面层部分和叶片之间的陶瓷构件10 因此,电场可能集中在具有优良耐热性的陶瓷构件10与雷电接收器1之间的界面处,使得可以有效地防止叶片5由于电力的集中而被损坏 在与闪电接收器1连接的叶片5的接口处,当捕捉闪电时,
