摘要
超高压变电站因为改扩建和所处声环境区域等级变化,受到的投诉和纠纷日益增多。本文对超高压变电站的主变、电抗器以及厂界的噪声进行了测量,并对噪声特性进行了分析。分析表明,高压变电站的主变、电抗器的噪声主要集中在中低频段,而厂界噪声为宽频带噪声,但100 Hz、200 Hz、400 Hz成分很强,具有显著的低频纯音特性。
Due to the regional level changes of Acoustic environment and reconstruction,the complaints and disputes of the high voltage substations are increasing.In this paper,the substation main transformer,reactor,and the boundary noise were measured,and the noise characteristics are analyzed.Analysis shows that the noise of the high voltage substation main transformer,reactor,mainly concentrated in low and middle frequency and noise is the wide-band noise at boundary of,but 100 Hz and 200 Hz and 400 Hz composition is very strong,has significant characteristics of low-frequency pure tone.
