Abstract

According to magneto-mechanical strong coupled effect, structure mode is discussed by engaging finite element (FE) method and both natural frequency and modal shape for a dry-type air-core reactor (DAR) are obtained in this paper. On the basis of harmonic response analysis, electromagnetic forces under sine-wave current excitation are mapped with the structure mesh, the vibration spectrums are gained and the consequences represent that the whole structure vibration predominates in the axial direction, with less radial vibration. Referring to the test standard of reactor noise, the rules of emitted noise of the DAR are measured and comparatively analyzed at power frequency and chosen other frequencies match the sample resonant frequency and the methods of active vibration and noise reduction are put forward. Finally, the low acoustic noise emission of a prototype DAR is verified by simulation and measurement.
