abstract:
An experimental platform was established to measure the vibration and noise of a transformer core under arbitrary interharmonic excitation. On this experimental platform, the influence of interharmonics on vibration and noise was investigated. The waveforms of vibration displacement and noise under different interharmonic excitation conditions were measured. Then, the influence of the frequency and amplitude of interharmonics on the vibration and noise of transformer core was investigated. The frequency characteristics of vibration displacement and noise of transformer core under interharmonics were summarized by frequency analysis. The results of this paper lay a theoretical foundation for further researches on the vibration and noise problems of power transformers and other equipment under interharmonics.
