摘要

特高压并联电抗器隔声装置的研制有助于特高压交流变电站的噪声治理。为此分析了特高压并联电抗器的噪声特性

通过结构设计、声学设计及密封设计研制了1台高性能隔声装置

该装置采用多层隔/吸声复合结构

显著提升了声学性能。通过试验验证了该隔声装置的声学性能

结果表明所得插入损失为31.8 d B

可有效地抑制中低频噪声;多物理场耦合仿真结果也表明该高性能隔声装置的插入损失可达32.1 d B

进一步验证了该隔声装置达到了预期设计目标。

Abstract

The development of high performance sound Insulation device is helpful for noise control of UHVAC substation. Therefore the noise characteristics of UHV shunt reactors were analyzed

and a high-performance sound insulation device was developed through structure design

acoustic design and seal design. The device adopts a multilayer sound absorption composite structure

which remarkably improves the acoustic performance. Its acoustic property was verified by tests. The results show that the insertion loss is 31.8 dB

which can effectively suppress the low-frequency noise. The results of multi physical coupling simulation also show that the insertion loss of the high-performance sound insulation device can reach 32.1 dB

and further verify that the sound insulation device achieves the expected design goal. The high-performance sound insulation device provides powerful equipment support for the noise control of UHV AC substation.
