摘要

随着人们对环境保护的关注

近年来电力系统对换流站滤波电容器噪声问题日益重视。当前

国内关于电力电容器的噪声试验的标准有2个

分别是GB/T 28543—2012《电力电容器噪声测量方法》和GB/T 32524—2016《声学声压法测定电力电容器的单元的声功率及和指向特性》

2个标准在噪声测点位置布置、测量面的选择等方面存在一定的差异。本文采用理论分析和试验验证的方法对此展开研究

希望给出一个较合理的电力电容器噪声试验方法

供科研单位及厂家参考。

Abstract

With people’s attention to environmental protection

in recent years

the noise of filter capacitor in converter station has been paid more and more attention. Nowadays

there are two standards for noise test of power capacitor in China

they are: GB/T28543-2012 noise measurement of power capacitors and GB/T32524-2016 acoustics-determination of sound power level and directivity character of power capacitor unit using sound pressure

which have some differences about location of measure points and selection of measure facets. This paper uses a theoretical analysis and experimental verification method to study

hoping to give a more reasonable method of noise test for power capacitors for institution and supplier to refer.
