摘　　要：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。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.
