摘要

在高压直流换流站中

电容器作为交流滤波器组中的基本元件对周围噪声的影响较大

而对它的噪声预测精确度与电容器辐射功率的确定密切相关。对电力电容器噪声产生的机理进行了分析。介绍了一些相应的声功率确定方法

并对其在电力电容器声功率确定中的优缺点和可行性作了比较。着重介绍了一种简易对比法

对于电容器厂家检测电力电容器噪声水平很有帮助。

Abstract

Power capacitors are basic components of AC filter bank in HVDC（High Voltage Direct Current） converter station.The influence of capacitors acoustic power on environmental noise level is very significant.The precision of noise level prediction has a close relation with the precision of capacitor acoustic power determination.In this paper

the generation mechanism of capacitor noise is analyzed.Several determination methods of acoustic power level are introduced

and their features and feasibilities are compared.A simple comparison measuring method is particularly discussed to help capacitor manufactures measure the noise level of power capacitors quickly and safely.
