摘要

从高压直流输电（HVDC）电容器噪声产生的基本规律出发

从声学原理的角度分析

提出了抑制电容器噪声的方法

取得了一些实际的经验

其中振动消能装置、隔音腔等单元降噪方法已经应用于工程实际并获得了国家专利。本文首先对弹簧减振器和共振吸声器进行了理论分析

得到共振型降噪措施的降噪效果不好的结论。噪声测试表明

在电容器单元底盖两端增加隔音腔是目前电容器噪声治理的最有效办法。

Abstract

In this paper

according to the basic law of producting noise in HVDC capacitor

the capacitor noise suppression method is analyzed and raised from acoustical principle prespective

some actual experience has been obtained.Noise reduction methods such as vibration energy decreased device and sound-insulation cavity etc.have been used in actual projects and obtained the national patent.Firstly

the spring shock absorber and resonance sound absorber are theoretically analyzed

and the obtained conclusion is that resonance-type of noise reduction measures is not very good.The noise test shows that the most effective way of capacitor noise suppression is install the insulation cavity at both ends of bottom cover capacitor unit.
