The results show that the resistance is mainly due to the electromagnetic force between the steel blocks, and the acoustic wave level increases with the increase of nominal capacity. The acoustic energy is mainly concentrated in one third of the central frequency of 100 MHz;The sound pressure distribution of the reactor is very complicated, with slow speed and obvious sound interference. Its scale increases as the business voltage increases, but is not related to the workload. Voice interference should be considered when calculating the noise of electrical equipment, and the accuracy of calculation should be improved. The noise is mainly regulated by the sound insulation cover with a maximum volume of 20db. This research can provide important support for the planning, design, control and management of high-voltage power stations.展开更多
