摘要
介绍了变电站的噪声控制措施,根据噪声超标排放的城市户外变电站布局特点提出了声屏障降噪方案,并设计了对低频噪声具有良好吸声作用的声屏障用吸隔声模块。经声学仿真和现场安装测试,声屏障降噪效果明显,站界噪声排放和敏感点处的声环境均能满足相关标准要求。该案例的成功实施为今后城市变电的噪声防治提供了借鉴和参考。
The noise control methods of substation are introduced.According to the layout characteristics of urban outdoor substation with excessive noise emission,the sound barrier scheme is proposed,and the barrier modules with sound absorption function is designed for low frequency noise.By acoustic simulation and field installation test,the sound barrier has obvious noise reduction effect,the acoustic environment of the substation boundary and sensitive point can meet the relevant standard requirements.The successful implementation of this case can provide reference for the noise prevention and control of urban substation.
