　　普惠风机的噪声控制方案

　　标准普惠风机噪声通常为75-95dB(A)。阻抗复合消声器可降低进出风口噪声15-20dB，弹性减振器减少结构传声12dB以上。某医院项目采用普惠风机配合消声房，使噪声从92dB(A)降至63dB(A)。最新研发的锯齿状叶片边缘设计，通过破坏涡流降低宽频噪声3-5dB。值得注意的是，管道振动会产生二次噪声，每10米应设置橡胶软连接。变频调速在降速20%时，噪声可降低约8dB。

　　10、心（3）发电机）发电机 发电机将风轮的机械能转换为电能，分为异步发电机和发电机将风轮的机械能转换为电能，分为异步发电机和同步发电机两种。异步发电机的转速取决于电网的频率，只同步发电机两种。异步发电机的转速取决于电网的频率，只能在同步转速附近很小的范围内变化。当风速增加使齿轮箱能在同步转速附近很小的范围内变化。当风速增加使齿轮箱高速输出轴转速达到异步发电机同步转速时，机组并入电网，高速输出轴转速达到异步发电机同步转速时，机组并入电网，向电网送电。风速继续增加，发电机转速也略为升高，增加向电网送电。风速继续增加，发电机转速也略为升高，增加输出功率。达到额定风速后，由于风轮的调节，稳定在额定输出功率
