摘　　要：现有的大多数变电站降噪材料,因降噪特性与变电站噪声频谱特征不匹配,以及耐候、耐久性不达标,很难长久限制噪声排放水平。由国网公司研发的新型吸声材料——微孔纤维复合吸声板克服了以上缺陷,该吸声板由铝纤维板和微穿孔板复合而成,具备"低频高效、宽频有效"的吸声特性,而且绿色环保、耐候耐久。微孔纤维复合吸声板加工而成的吸声壁面、消声器、声屏障和隔声罩已在多座变电站降噪工程中投入使用,将站界噪声控制在GB 12348—2008《工业企业厂界环境噪声排放标准》的限值要求之下,在城区变电站降噪领域中显示出广阔的应用前景。Due to the mismatch of noise reduction performance and the frequency feature of substation noise, the poor weather resistance and durability, most substation noise reduction material cannot limit the noise emission for a long time. Microporous fiber composite acoustic board, developed by the State Grid Corporation, conquers the shortcomings of traditional material. It consists of Aluminum fiber board and micro-perforated panel, with the sound absorption feature of large low-frequency absorption coefficient, good absorbing ability for wide frequency, environmental friendly performance and good weather resistance and durability. Microporous fiber composite acoustic board has been made into sound-absorbing wall, muffler, sound barrier and sound insulation cover and applied to the noise control engineering of substations, which makes the noise level of station boundary reach the GB12348—2008 Emission Standard for Industrial Enterprise Noise at Boundary. It has great potential in the area of noise control for urban substations.
