Gaoya 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 ...

Dianci bileiqi由于复合绝缘子自身结构的特点，其沿面电场分布极不均匀，在湿度较大或凝露出现时容易引发水珠电晕放电现象从而加速复合绝缘子伞裙和护套的老化，严重时还会引起闪络事故。安装均压环能够降低和转移局部最大场强，降低电场不均匀程度。本研究基于多物理场仿真软件建立了实际线路铁塔、导线、绝缘子的三维塔线模型，应用有限元法进行电场仿真计算，应用控制变量法研究了在大小均压环配置情况下，均压环环半径、管半径、屏蔽深度对电场分布的影响，得到了500 kV紧凑型线路单V串大小环配置的均压环方案。结果表明，在优化均压环配置下 ...
