The vibration and noise produced by the anode saturable reactor (ASR) in the HVDC transmission converter valve are very serious, and the long-term vibration can accelerate the aging of the equipment and damage the friendly environment. In this paper, a core with race-track shape from the ASR in ±800 kV/4750 A project is used as the research object. An excitation winding is wounded on the core, and the vibrations and noises are measured when the winding is excited respectively by sine wave and rectangular waves at different frequencies. In order to reduce the noise, the polyurethane damping elastomer is filled into the box of core, and the vibrations and noises of core with polyurethane damping elastomer under different excitations are measured. The results show that the polyurethane damping elastomer can efficiently reduce the vibrations and noises of the anode saturated reactor core, especially under non-sinusoidal excitation. This research is of significant reference value for the vibration and noise reduction of ASR and other high frequency equipment.
