电力电容器单元噪声试验及降噪方法探讨

Research on Noise Test and Noise Reduction of Power Capacitor Unit

叙述了对电力电容器单元噪声问题的测量方法、噪声的影响因素以及抑制噪声所采取的措施,重点介绍了电容器噪声产生、测量方法、影响因素以及应对措施方面研究的成果和存在的一些问题。利用文章中提出的方法可以有效、方便地降低电容器及电容器装置的噪声等级,为电容器单元降噪及换流站的建设提供参考。

The noise measurement method, influence factor and measures to suppress the noise of the power capacitor unit are described, with emphasis introduction content are noise generation, measurement method, influence factor and countermeasures. The noise level of the capacitor and capaci- tor device can be reduced effectively and conveniently through use the method which proposed in this paper, so to provide reference on the noised reduction of capacitor unit and construction of converter station.
