Research on Low Frequency Vibration Reduction of Transformers Based on Particle Damping

Abstract

Taking a certain type of transformer as the research object, a solution based on particle damping is proposed for the problem that low-frequency vibration is difficult to control. Firstly, energy consumption model for transformer based on particle damping is established, and the optimal design parameters such as particle size and particle filling rate are determined by discreteelement method(DEM). Secondly, the transformer is modified and the damping effect is verified by experiment. The results show that when the vibration damping base adopts the design scheme of iron-based alloy particle 1 and iron-based alloy particle 2,particle size of 3mm and filling rate of 80%, the total acceleration effective reduction of the four measurement points are 66.67%, 53.09%, 66.23 % and 86% The solution is important to reduce the low frequency vibration of substation equipment.
