220 kV露天变电站的噪声污染及其控制简析

摘要

Based on the noise data of several multiple 220kV outdoor substations, the major noise sources, noise intensity, frequency characteristics, propagation characteristics and noise pollution situation of the substations were described. According to the noise sources and noise transmission routes, the noise control measures were briefly analyzed. Examples were given to clarify the actual noise reduction effect of various noise reduction measures. This work can be used as a reference for similar engineering projects.%城市220 kV露天变电站的噪声污染比较严重，有必要进行分析和噪声治理。基于多个220 kV露天变电站的噪声实测数据，阐述220 kV露天变电站的主要噪声源、噪声源的声压、频率特性、传播影响特性以及对周边环境的污染情况，从声源、噪声传播途径简要分析了220 kV露天变电站的噪声控制措施，并以实例加以说明，阐述各种降噪措施的实际降噪效果，可供同类工程参考。
