变压器降噪技术研究与应用进展

Research and Application Progress on Noise Control of Transformers

变压器噪声污染是目前城市快速发展中急需解决的问题.文章从变压器噪声来源入手,针对变压器结构,分别从变压器本体噪声的抑制、传播途径中对噪声的抑制和变压器外围结构对噪声的抑制等3个方面,综述与分析了目前变压器降噪技术的研究与应用进展.对比发现,主动降噪措施是一种很具有针对性的降噪措施,但系统的设计和算法的复杂程度使这种方法目前尚未得到广泛使用;相对而言,设计高性能轻薄隔音材料用于变压器的隔音层是性价比很高的变压器降噪措施.

With the improvement of people’s living standard,noise pollution of transformer needs to be solved urgently.Starting from the source of transformer noise,this paper describes and compares the existing measures of transformer noise reduction from the three aspects of the noise suppression of transformer itself,the noise suppression of transmission path and the noise suppression of transformer peripheral structure.It is found that the active noise reduction measure is a very targeted noise reduction measure,and the system design and the complexity of the algorithm make this method not widely used.In general,designing a lightweight sound insulation material with high performance for the insulation layer of transformer is a more convenient and long-term noise reduction measure.
