特高压变电站降噪用吸声材料及结构研究

Research on Sound-Absorption Materials and Structure for UHV Substation Noise Reduction

通过对特高压变电站噪声源及特性的分析,以及对特高压变电站降噪用传统和新型吸声材料的比选,选择了2种新型吸声材料——铝纤维板和聚合微粒板作为特高压变电站降噪用吸声材料,并设计出适合于特高压变电站工程应用的复合吸隔声结构,其低频吸声性能优良、耐候性良好、易收回利用、绿色环保无二次污染,是特高压变电站降噪的理想材料,在变电站降噪工程中值得推广。

Through the analysis of the noise sources and characteristics of UHV substations and the comparison of conventional and new sound-absorbing materials for noise reduction of UHV substations, two new types of sound-absorbing materials, aluminum fiberboard and polymerized particle board, were selected as UHV substations. The sound absorption material for noise reduction is designed and a composite suction sound insulation structure suitable for UHV substation engineering applications is designed. The low frequency sound absorption performance is excellent, the weather resistance is good, the recovery is easy to use, and the green environment is free from secondary pollution. It is an ideal material for noise reduction in UHV substations and is worthy of promotion in substation noise reduction projects.
