摘　　要：广西某110 kV城区变压站围墙外1 m噪声超标严重,附近居民投诉较多。为解决该变电站噪声超标问题,利用变压器噪声衰减计算软件分析各种噪声治理措施的合理性和经济性。根据计算结果进行分析,得出在变压器西侧约3 m处增设厚200 mm、高5 m的微孔纤维复合吸声板吸声墙是最有效的治理措施。该措施实施后,围墙外1m及噪声敏感点的噪声值均符合标准要求。The 1 meter noise outside the wall of an 110 kV urban substation seriously exceeds the standard in Guangxi, which caused more complaints from nearby residents. In order to the noise exceeding the standard problem of the substation, reasonability and economy of all noise control measures are analyzed by the transformer noise attenuation calculation software. By the analysis based on calculation results, it is obtained that the most effective control measures is the addition of a 200 mm thick and 5 meter tall micro fiber composite sound absorption board wall at about 3 meters of transformer west side. After the implementation of the measure, all the noise values at 1 meter outside the wall and sensitive points meet the standard requirements.
