摘要

近年来

随着国家特高压直流输电线路的快速建设

换流站滤波电抗器产品的噪声问题越来越受到重视。文中对干式空心电抗器产品的噪声产生机理、声级测试方法和降噪措施进行研究

重点讨论电抗器产品本体降噪和噪声传播途径降噪两方面内容。通过试验对比验证了多种降噪措施的降噪效果

并提出了一种能够有效降低电抗器产品噪声水平的降噪装置

实现降低产品噪声10 dB以上效果。新型降噪装置在特高压直流输电工程换流站噪声改造项目中得到应用

并取得了良好效果。

Abstract

This paper discusses the noise generation mechanism

sound level test method and noise reduction measures of dry-type air-core reactor products

with emphasis on noise reduction of reactor body and noise transmission route. A variety of noise reduction measures were verified experimentally

and an novel noise reduction device was proposed in this study

which could reduce noise level by more than 10 dB. This noise reduction device was applied to the UHVDC transmission project and achieved good results.
