针对配电设备振动引起的结构噪声扰民问题，提出了基于粒子阻尼技术的振动噪声控制方案。建立变压器粒子阻尼的能耗模型，根据能耗模型的耗能值对粒子参数进行优化，并根据仿真得到的参数方案加工样机进行试验验证。试验结果表明：粒子阻尼器采用两种铁基合金粒子搭配使用、粒径为3 mm、填充率为80 %的填充方案时，配电房一楼和二楼测点的加速度总有效值分别降低66.68 %、88.33 %，噪声幅值分别降低14.53 dB、7.02 dB。所提方案为配电房领域的降噪设计提供了新的手段。

A vibration and noise control scheme based on particle damping technology is proposed to address the problem of structural noise disturbance caused by vibration of power distribution equipment. An energy consumption model for transformer particle damping is established, particle parameters based on the energy consumption value of the energy consumption model are optimized, and the prototype is processed based on the parameter scheme obtained from simulation for experimental verification.The experimental results show that when two types of iron-based alloy particles are used in combination with the particle damper, with a particle size of 3 mm and a filling rate of 80 %, the total effective acceleration values of the measurement points on the first and second floors of the power distribution room are reduced by 66.68 % and 88.33 % respectively, and the noise amplitudes are reduced by 14.53 dB and 7.02 dB respectively.The proposed scheme provides a new means for noise reduction design in the field of power distribution rooms.
