摘要
针对220kV和110kV两个电压等级,根据设定的边界条件选取安徽电网中的典型变电站,开展其主变噪声的距离衰减特性试验,分析主变噪声在水平方向上的传播规律和影响因素,并确定其距离衰减模式,为变压器降噪技术、新建变电站工程环境影响评价及变电站噪声污染治理提供参考。
Several typical 110 kV and 220 kV transformer substations in Anhui power grid were selected for the ex- periments of the characteristic of noise made by the transformers, based on the given boundary conditions. The methods and the apparatus of the experiments were both designed newly. Mainly focusing on the main trans- formers,the feature experiments are conducted on the distance decay of its noise, aiming to analyze the main features and propagation law of the noise of the main transformers, probe into the model of its environmental im- pact,and provide fundamental data for the assessment of the environmental impact resulting from transformer substation construction. The results revealed the differences of the propagation law between the near field and far field in the sound field of substations,which gived a new idea for the boundary noise forecast. And the con- sideration about the difference between the equal A and equal C noise could provide some advice for the noise pollution control of transformer substations.
