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.
