主变压器室内降噪改造探讨

Approach on Lowering the Noise Level of in-door Transformer

针对市区一户内变电站噪声超标问题,通过分析了该室内变电站噪声源的特点,提出降低噪声改造方案。现场实测数据证明该降噪方案有效,能使变电站周围噪声水平符合规范要求。

In view of noise level over proof of an in-door transformer, through analyzing the characteristics of the noise sourcing from in-door transformer, renovation scheme for lowering noise level is proposed. The measured data in site has proven that this renovation is effective. The noise level has been lowered down within the requirement of the code.
