摘要

本文针对某小区配电变压器低频噪声超标问题

根据低频噪声传播特性

提出了低噪声配电变压器更换、加装减振器、优化变压器防护罩设计等多方面噪声治理措施。现场应用结果表明综合治理措施取得了良好效果

居民房间中的A声级和倍频带声压级均可达到噪声排放限值要求。

Abstract

With the economic and social development

more and more attentions have been paid to the low-frequency noise caused by indoor distribution transformers. In order to solve the problem that the low-frequency noise of an indoor distribution transformer

the comprehensive control measures had been put forward based on the propagation characteristic of the low frequency noise

including changing low noise distribution transformer

equipping with shock absorber

optimizing the design of the transformer shield. Field application results showed that the A-weighted sound pressure level and that in octave bands of the residents’ home can meet the demands of noise emission limits

which means that the control measures have achieved good effects.
