| 摘 要： | 摘要：城市户内变压器运转时会产生噪声，严重时会影响到周围居民的正常工作和生活。文章简单阐述了变压器噪声产生和传播机理。并以南昌市某户内变电站为例，使用声振软件Va One,基于统计能量方法，对经过吸声材料处理后的户内变声场进行仿真模拟。模拟结果表明：经过添加特殊吸声材料处理后的户内变电站，在大门外，仿真数据与实测值吻合良好；在大门内、外，声压级差值仿真结果与预期效果能够符合。

| Abstract: | Urban indoor transformer operation will produce noise, even affect the normal work and life of surrounding residents when serious. This article, describes the transformer noise generation and propagation mechanism simply. And applying the software VA One, based on statistical energy analysis method, the sound filed of a substation transformer chamber in Nanchang is taken as an example to be simulated. According to the simulation results, SPL simulated is in good agreement with the measured values outside the door with adding sound-absorbing material in main transformer room. The difference of SPL between inside and outside the door is correspond to respected. |
