摘要
近年来我国输变电技术快速发展,高压输电线路深入城区,引起噪声投诉问题增多。为有效控制户外变电站的噪声影响,提出了一种声屏障模块化降噪设计方法,该方法通过查询降噪材料数据库,进行隔声材料优选;通过建立声屏障仿真模型,结合工程应用经验,获得了不同高度、不同安装位置的声屏障降噪效果。采用该方法,完成了某500kV户外变电站的声屏障设计与应用,经站界和敏感建筑物内噪声检测,声屏障安装后噪声排放满足《工业企业厂界环境噪声排放标准》(GB 12348—2008)中Ⅱ类声环境功能区的要求。
The power transmission and transformation technology has developed rapidly in recent years.The high-voltage transmission lines distributes in urban areas,causing the complaining problems of noises.In order to control the noise influence of outdoor substation,this article proposes a modular de-noise design method of sound barrier.This article uses this method to choose the sound insulation materials through a database of noise reduction materials.Based on the establishment of sound barrier simulation model,the article combines the engineering application experiments and acquires the noise reduction effect of sound barriers with the different heights and the different installation positions.The article adopts this method and completes the sound barrier design and application of an outdoor substation with voltage of 500kV.After the installation of sound barrier and through the noise tests in the substation boundary and sensitive buildings,the noise emissions meet the demand of typeⅡnoise environmental functional areas in Standard GB 12348—2008.
