Description

technical field [0001] The present application relates to the technical field of electric power equipment, in particular to a vibration reduction method, device, equipment and storage medium for power transformer windings. Background technique [0002] With the enhancement of people's awareness of environmental protection and health, the vibration and noise problems of transformers have been highly valued by environmental protection departments, power supply departments and transformer manufacturers. The vibration and noise of the power transformer mainly come from the vibration of the winding and the iron core. During the operation of the transformer, when the natural vibration frequency of the winding is equal to or close to the excitation frequency of the winding, the winding will generate greater vibration. [0003] In the prior art, the natural vibration frequency of the winding is usually adjusted by adjusting the stiffness of the winding, so that the natural vibration...
