摘　　要：将声振解耦吸音板隔声屏障应用到特高压变电站中,以解决特高压变电站噪声源设备厂界噪声不达标的问题。声振解耦吸音板隔声屏障由声振解耦吸音板、振动解耦隔振器等部件组成,是一种装设在设备油箱外侧、散热器内侧的高效降噪装置,具有降噪性能好、不需要改变设备内部结构、通用性强、经济性好等特点。噪声测试结果表明,安装声振解耦吸音板隔声屏障后,设备排放噪声可减少15 dB(A)左右,满足了有关标准的要求。The acoustic barrier with sound-vibration-decoupled noise-absorbing panels is ued in ultra-high voltage substation to address the issue that the factory noise at boundary of noise sources in ultra-high voltage substation does not meet the standard requirements.The acoustic barrier with sound-vibration-decoupled noise-absorbing panels,which is composed of sound-vibration decoupled noise-absorbing panels,vibration-decoupled vibration isolators,and other components,is an efficient noise reduction device.The acoustic barrier is installed on the outside of the equipment oil tank and the inside of the radiator,featuring good noise reduction performance,no need to change the internal structure of the equipment,good versatility and economy.The noise test results show that after the installation of the acoustic barrier with sound-vibration-decoupled noise-absorbing panels,the emission noise is reduced by about 15 dB(A),meeting the requirements of relevant standards.
