500 kV地面变电站的站区面积大，主要噪声源是500 kV变压器，变压器的数量多，分布广，十余台变压器辐射的噪声使变电站边界噪声超标。以一座500 kV地面变电站为例，分析变电站站区边界环境噪声的排放情况，提出一些在不改变变电站主体前提下的噪声治理技术措施，可供同类工程设计参考。
500 kV地麵變電站的站區麵積大，主要譟聲源是500 kV變壓器，變壓器的數量多，分佈廣，十餘檯變壓器輻射的譟聲使變電站邊界譟聲超標。以一座500 kV地麵變電站為例，分析變電站站區邊界環境譟聲的排放情況，提齣一些在不改變變電站主體前提下的譟聲治理技術措施，可供同類工程設計參攷。

An urban 500 kV substation on the ground usually covers large area, whose main noise sources are from the 500kV transformers. There are more than a dozen transformers widely distributed in the substation. So, noise from those transformers will make the noise in the substation boundary to exceed the critical value. In this paper, taking a 500 kV ground substation as an example, the noise situation in the substation boundary was analyzed, and the noise control technical measures without changing the main condition of the substation were put forward. This work may provide a reference to similar engineering projects.
