摘要
高压并联电抗器是特高压变电站内主要的设备噪声源之一,成为特高压变电站噪声控制的重点。在尽可能降低设备本体噪声的前提下,采用高抗隔声罩是较有效的降噪辅助措施。在深入分析1 000 kV高抗噪声水平及频谱特性的基础上,对高抗隔声罩的应用情况进行了详细介绍。高抗隔声罩已在晋东南变电站成功应用,并取得了预期的效果。
1 000 kV reactance,as one of the main noise sources,has become the focus of noise control in UHV substation.In addition to decreasing the noise of reactance itself as possible,BOX-IN may be the most effective assistant measure of noise reduction for UHV reactance.On base of the analysis of the characteristics and spectrum signature of UHV reactance noise,this paper discusses the application of UHV reactance BOX-IN,which has been realized in 1 000 kV Jin Dong-nan substation and been proved to be active.
