In sensitive areas such as residential areas, commercial centers and precision industrial facilities, the problems of inherent vibration and low-frequency noise caused by the inherent vibration are increasingly prominent when a transformer operates, the mechanical life of equipment and connecting parts can be influenced by excessive vibration, and continuous noise pollution can cause interference to surrounding environment and personnel health. Therefore, the vibration and noise reduction measures of the transformer become key links for guaranteeing long-acting stable operation of equipment and meeting the environmental protection requirement. The traditional transformer vibration and noise reduction scheme has certain limitations. Common single-layer vibration-damping pad or independent sound-proof cover structure is difficult to simultaneously and effectively damp broadband vibration and solid sound transmission generated by the transformer under the actions of starting, load change and electromagnetic force. The single vibration reduction element has insufficient effect of inhibiting the vibration in the complex direction, and creep or performance degradation is easy to occur after long-term use, so that vibration isolation failure is caused. In addition, although the fixed sound insulation structure can block air noise to a certain extent, the fixed sound insulation structure lacks dynamic linkage with the vibration state of the transformer, so that the optimization of noise reduction efficiency is difficult to realize, and meanwhile, inconvenience is brought to daily inspection, heat dissipation and ventilation of equipment. There remains a need for a more integrated and efficient systematic solution for the overall blocking of vibration transmission paths, multi-level energy dissipation and adaptive control of noise.
