为调查户内配电变压器噪声对居民生活的影响，对某受到噪声污染投诉的户内变压器进行噪声污染检测，结果显示室内房间的LAeq值和倍频带声压级均超出了国标规定的限值。对测试结果进行系统分析，发现其噪声污染源主要来自于室内变压器的低频结构噪声。在此基础上提出隔振设计的治理措施和方案，取得良好的效果，治理后该住宅户内的噪声检测数据全部满足国标规定的限值要求，该研究结果可为城市户内配电房设计和噪声污染控制提供重要的参考依据。%In order to investigate the effect of indoor distribution transformer's noise on residents' life, the noises of indoor distribution transformers, which were complained by residents due to the noise pollution, were measured. The results show that both LAeq and 1/1 octave spectrum exceed the domestic emission standard, and the noise is mainly the structural noise of the indoor transformer. On this basis, a vibration isolation scheme is put forward, the results of noise control are proven to be good, and the noise can meet the relevant standards. This study has provided a reference for noise control during the design and construction process of indoor distribution transformers.
