| 摘 要： | 针对变压器噪声的不良影响，提出基于分布式动力吸振的减振降噪措施。以某10 kV油浸式变压器作为研究对象，建立变压器-分布动力吸振器系统有限元模型，对比分析添加分布式动力吸振器前后变压器箱体的动力响应及声场。结果表明分布式动力吸振对变压器箱体振动抑制效果明显，场域内A计权声压级最大值降低约4 dB（A），1m远场最大降噪效果接近2.1 dB （A）。

| Abstract: | Targeting the adverse effects of transformer noise， the paper proposes the vibration and noise reduction measures based on distributed tuned mass damper. Taking a 10 kV oil transformer as the research object， the finite element model of the transformer-distributed tuned mass damper system is established. A comparative analysis is done of the dynamic response and sound field of the transformer box with and without the distributed tuned mass damper. The results show that the distributed tuned mass damper has significant suppression effect on the transformer box vibration， the maximum of A-weighting sound pressure level in the field is reduced about 4 db （A） and the maximum noise reduction of 1 m far field is close to 2.1 db （A）. |
