The substation’s production of low-frequency noise will have a significant impact on individuals’ physical and emotional well-being, as well as their everyday functioning, resulting in detrimental effects on the human body. This research aims to examine the classification, preparation method, and key parameters that influence the damping performance of damping materials in order to mitigate the vibration and noise associated with transformer equipment. These criteria include compatibility, temperature, copolymerization, crosslinking degree, and filler. This study investigates and develops a magnetic damping material that utilizes waste rubber as a resource, along with the corresponding preparation technique. By improving the material ratio, the temperature range of the damping material is expanded, resulting in enhanced efficacy in suppressing low frequency vibrations within this temperature range. The simulation study of the damping material laying is conducted, taking into account the physical properties of the damping material and the actual structure of the transformer. This study aims to optimize the vibration and noise reduction effect of the transformer surface, enabling effective noise control within the frequency range of 100-1000 Hz. The overall noise level experiences a decrease of 5.1 dB(A), whereas the highest reduction in peak noise can exceed 10 dB(A). Enhancing and refining the damping patch material can significantly enhance the performance of vibration and noise reduction, thereby serving as a crucial technical avenue for mitigating transformer noise pollution.
