邻近居民楼10 kV杆式变压器噪声影响与治理措施

Noise Pollution and Control Measures of 10 kV Rod Transformers near Residential Buildings

主要阐述城市电网中数量众多的10 kV杆式变压器的噪声特性及噪声传播产生的影响,并分析邻近居民楼的杆式变压器产生的噪声对居民楼的影响程度,提出采用单侧隔声屏罩、全封闭隔声屏罩的降噪方案,并通过现场试验对其进行论证。

The noise characteristics and noise propagation effects of 10 kV rod transformers in urban power grid are described. The impact of noise of the transformers on the adjacent residential buildings is analyzed. The noise reduction measures of unilateral noise barrier and closed noise barrier are proposed and verified by in-situ tests.
