| 摘 要： | 户外箱式配电变压器因变压器本体噪声或通风散热风机噪声的扰民投诉日益增多。针对户外箱式配电变压器噪声扰民案例，通过理论计算与实际经验相结合，进行隔声罩降噪设计，隔声罩采用自然通风为主辅助机械通风的通风散热设计。通过对案例实际测量，结果表明自然通风式隔声罩降噪、通风效果良好。

| Abstract: | The complaints for the noises of the outside box-switchboard transformer and the cooling fans increase recently.Based on the complaint cases,an acoustic enclosure for noise-decreasing is designed through the theoretical and experimental analysis.The acoustic enclosure is ventilated mainly through natural ventilation with the auxiliary mechanical aiding.The results of measurement show that the acoustic enclosure with natural ventilation has fine effects in both ventilation and noise-reduction. |
