10 kV油浸式变压器结构降噪优化设计

open access: yesGaoya dianqi
配电变压器噪声问题突出,文中通过分析变压器表面振动噪声特性及模态参数,提出了10 kV变压器油箱结构优化措施。对10 kV配电变压器进行了振动测量,并仿真计算了变压器各结构对辐射噪声的贡献,分析得到油浸式变压器振动最大位置为距离底部20 cm左右处,振动主要能量集中在100、200、300 Hz上,油箱正面和背面对噪声辐射声功率贡献最大。通过分析油箱结构模态参与因子,获得了油箱的优势模态,确定了油箱优势模态振型的最大位置,计算结果与测量基本相同,在此基础上采取附加质量块来优化油箱结构振动分布 ...
