- W4283268618 abstract "Abstract To realize the state diagnosis of transformer by detecting the running sound signal of transformer, it is necessary to obtain the sound pressure distribution of transformer in normal state. Because the amplitude of the sound signal changes obviously during the operation of the transformer, this paper studies the overall operation noise of the transformer and verifies it with the sound signal collected on site. The multi physical field coupling analysis software COMSOL multiphysics is selected to solve the vibration acceleration and sound pressure distribution of dry-type transformer under rated state. By comparing the solution with the field data, the sound pressure law of the transformer under normal operation is studied." @default.
