摘要
变压器是变电站内主要的噪声源之一。以某750kV变电站变压器噪声实测数据为基础,结合工程实际,基于Cadna/A噪声预测软件模拟得到变压器两种典型声源分布下空间声场等声级线的分布图,并模拟得到三相(台)主变在两种声源分布下的衰减曲线。为研究变电站噪声预测、声环境影响分析评价及噪声治理方案设计提供参考。
Transformers are the main acoustic source of substations.Based on the measured data of transformer noise of a 750kV substation,combined with engineering practice,using Cadna/A noise prediction software,the distribution of sound level lines of sound field and attenuation curve of the main transformer under two typical acoustic source distributions of transformers is obtained.That provide reference for the study of substation noise prediction,acoustic environmental impact analysis and evaluation and the design of noise control.
