本发明涉及垂直轴风力发电机， 尤其是能够强风引起发电机失速的装 置及方法。 背景技术
风力发电机刹车机构的主要作用有两方面： 一是设备检修时需要将风 力发电机组的叶片固定不动， 二是遇到风力特别强力或者台风时为避免损 坏发电机组需要将风力发电机组的叶片固定不转。 现有风力发电机的刹车 方式主要有机械式的刹车机构和变浆式的刹车***。 机械的刹车机构一般 是由刹车盘、 刹车块和液压控制装置组成的液压刹车机构， 该种刹车机构 的刹车盘固定在电机组的主轴上， 刹车块由液压控制装置控制。 当遇到风 力特别强力或者台风时， 为保护风力发电机组因超功率发电而受到损坏， 液压控制装置控制刹车块夹紧主轴， 使其减慢速度， 从而限制了发电机的 转速， 改刹车过程中一直将全部的作用力都加在刹车片上， 这使得机械振 动大， 刹车片磨损快， 也不适合日常的维护； 变浆式的刹车***是通过改 变叶片的迎风面积来达到减少叶片的受力， 从而降低叶片的速度， 该种方 式在一般的强风下可能有用， 但是对于台风级的风力来说， 该种刹车方式 存在很大的风险， 刹车效果一般。上述两种刹车方式均存在一个关键问题， 即使刹车凑效， 风力发电机的叶片也很有可能被强风吹断， 造成发电机组 的损害。 发明内容
