| 摘 要： | 为了改善变电站噪声环境、推进特高压工程建设,通过电晕笼和金具试验测量到的导线及金具噪声频谱,归纳出了电晕噪声主要频谱特性;通过测量特高压交流试验基地及特高压示范工程变电站内变压器的噪声,归纳出了变压器噪声主要频谱特性。在对特高压交流试验基地变电构架噪声进行实测的基础上,分析了特高压交流试验基地变电构架下各噪声源特征频率的分布,得出在合理设计均压环及母线的情况下,变电构架可听噪声对总体噪声贡献很小的结论。该结论可用于指导治理变电站的可听噪声。

| Abstract: | The audible noise from EHV and UHV substation will affect the environment. In order to improve the noise environment,and to promote the UHV projects,we summarized the main spectrum characteristics of the corona noise from corona cage and hardware fittings testing,and those of the transformer noise from UHV AC Test Base and UHV demonstration project. On the basis of the measurement of the noise in the transforming region of UHV AC Test Base,we analyzed the distribution of the spectral characteristic,and conc... |
