湖南省阳洞滩电站研究治理噪声有成效,使运行场地噪声由91dB降低到72dB,为高水头电站降低噪音作出了样板。该电站建成于1978年,装机容量为2 000kW,利用水头102m,主厂房为钢筋混凝土半封闭式。机组运行时,机械性噪声和流体噪声混合,形成较大的稳态噪声,加上厂房墙面拌灰,混响时间长,最大噪声达98dB,致使运行工人听力减弱,食欲不振,头晕失眠,精神萎靡。这一情况引起了领导重视。在怀化地
The Yangdongtan Hydropower Station in Hunan Province has done a lot in research and management of noise, reducing the noise in the operation site from 91dB to 72dB, making a model for reducing the noise of high-head power plants. The power station was built in 1978, with an installed capacity of 2 000 kW and a water head of 102 m. The main plant is semi-enclosed with reinforced concrete. During the operation of the unit, mechanical noise and fluid noise are mixed to form a large steady-state noise. With the addition of ash on the wall of the plant, the reverberation time is long and the maximum noise is up to 98dB, resulting in weaker hearing, loss of appetite, dizziness and insomnia, Apathetic This situation has drawn the attention of leaders.
