摘要
简要介绍220 k V露天变电站中变压器的噪声源强、频率特性与传播影响特点,以上海城区首次实施的两座220 k V露天变电站声屏障工程为实例,阐述这两个声屏障工程实例的概况、特点、降噪效果及其他相关技术因素,并总结220 k V露天变电站中的声屏障工程经验,可供同类工程参考借鉴。
This paper introduced the noise intensity,frequency characteristics and propagation characteristics of transformer in the 220 k V outdoor substation. Taking the noise barriers applied in the two 220 k V outdoor substation in shanghai as an example. the paper introduced the basic situation,the effect of noise reduction and other related technical characteristics of the two noise barriers,and summarized the experiences of noise barrier applied in 220 k V outdoor substation,which could be reference to the same project.
