为了降低逆变电源供电下电抗器的噪声，需要研究噪声产生的原因。为此，我们已经提出了一个三维振动分析，考虑电磁和磁致伸缩，所提出的方法被应用到一个阶段的反应器。结果发现，在轭的反应器的位移是大的和插入在铁芯之间的间隙的绝缘子的硬度影响的位移。然而，没有进行降低噪声的优化设计。本文首先通过结构静力学分析确定了较佳的间隙硬度，并提出了一种新的设计方案以降低噪声。此外，通过振动分析和实验研究了改进的间隙硬度和所提出的电抗器新设计的有效性。
To reduce the noise of a reactor under inverter power supply, the cause of noise should be investigated. For this purpose, we have already proposed a 3-D vibration analysis considering electromagnetism and magnetostriction, and the proposed method was applied to one phase of a reactor. It was found that the displacements in the yoke of the reactor are large and the hardness of insulators inserted in the gaps between cores affects the displacements. However, the optimal design to reduce the noise is not carried out. In this paper, first the better hardness of the gaps are determined by using the static structure analysis and a new design is proposed to reduce the noise. Moreover, the effectiveness of the improved hardness of gaps and the proposed new design of reactor is investigated by using the vibration analysis and the experiment.
