控制换流变压器的噪声是降低换流站周围厂界噪声的关键,常用的声屏障难于实现在远离换流站处的噪声控制。对BOX-IN隔声结构的隔声性能采用SoundPLAN软件和实际测试进行了研究,结果表明:BOX-IN结构的降噪性能优于声屏障,尤其是在远离换流站处;对于换流变压器400 Hz主要噪音,BOX-IN的隔声效果很好。
控製換流變壓器的譟聲是降低換流站週圍廠界譟聲的關鍵,常用的聲屏障難于實現在遠離換流站處的譟聲控製。對BOX-IN隔聲結構的隔聲性能採用SoundPLAN軟件和實際測試進行瞭研究,結果錶明:BOX-IN結構的降譟性能優于聲屏障,尤其是在遠離換流站處;對于換流變壓器400 Hz主要譟音,BOX-IN的隔聲效果很好。

To control the noise of converter transformer is a key to reduce the audible noise at the boundary of the HVDC substation,and it is hard for the usual noise barrier to control the noise at the range of a long distance from substation.The paper researches the noise-reducing performance of BOX-IN construction for converter transformer with Sound Plan software and noise test in field,indicating that the BOX-IN construction is better than the noise barrier,especially at the range of a long distance from substation,and has a good performance to reduce the main noise at 400 Hz level from the converter transformer.
