变压器噪声是变电站噪声的主要来源。对主变声源特性以及降噪原理进行了分析研究，详细介绍了降噪处理方法，在此基础上给出了一套综合通用的治理变压器噪声的有效措施，并将其应用于现有变电站，降噪效果明显且符合国标要求。在不影响运行检修工况下最大化降噪处理，同时保证了主变的通风散热量与温湿度实时控制，采用开挖地下通风道降噪与围墙隔音等创新性措施，为治理主变噪声提供了理论与实践依据。

The main noise source in transformer substations is the noises of transformers .This paper makes an analysis and research on the acoustic source characteristics of the transformer and the princi‐ples of noise reduction .T he method of noise reduction is introduced in detail .Based upon above anal‐ysis ,a universal and effective measure to transformer noise reduction is proposed noise .Testing re‐sults show that the presented measure meets the international standard w hen applied to transformer substations in practice .Moreover ,the proposed measure can ensure the ventilation and heat dissipa‐tion of main transformers ,real‐time monitoring both temperature and humidity without affecting the operation condition in running and service ,w hich provides both theoretical and practical basis of other noise treatment for main transformers .
