A Transformer Vibration and Noise Reduction Structure

Abstract

The invention discloses a vibration and noise reduction structure of a transformer. The vibration and noise reduction structure comprises a transformer elastic bracket and a glass fiber reinforced plastic sleeve; the glass fiber reinforced plastic sleeve is embedded in the inner surface of the transformer elastic bracket; the top end of the glass fiber reinforced plastic sleeve is connected with arubber cushion plate through a rubber ring; a bearing plate is arranged on the upper surface of the rubber cushion plate; the left end of the bearing plate is connected with the rubber cushion platethrough an adjustment bolt; a spring washer is also arranged between the adjustment bolt and the rubber cushion plate; a base is fixedly mounted at the right end of the bearing plate; the upper surface of the base is connected with the surface of the bearing plate through under-block cushion adhesive; a transformer bottom bracket is fixedly mounted on the upper surface of the bearing plate; a spring strip is also arranged at the left end of the transformer bottom bracket; the bottom of the spring strip is connected with the bearing plate; and by virtue of elastic cushion adhesive and the elastic bracket, generation of vibration is reduced, so that noise can be controlled.

Description

technical field [0001] The invention relates to the technical field of transformer vibration reduction and noise reduction, in particular to a transformer vibration reduction and noise reduction structure. Background technique [0002] In recent years, due to the continuous growth of industrial and agricultural production and residential electricity consumption, the density of urban electricity loads is increasing. With the continuous expansion of cities and the needs of urban power grid construction, the installation locations of transformers are getting closer to urban areas and In residential areas, many large-capacity substations are successively built in urban areas, and small and medium-capacity transformers are widely installed in residential areas, making the vibration and noise problems caused by transformers increasingly prominent: [0003] (1) At present, there have been many researches on transformer core materials and installation processes, and gratifying resul...

AI Technical Summary

Problems solved by technology

[0003] (1) At present, there have been many researches on transformer core materials and installation processes, and gratifying results have been achieved. The space for further improvement is limited, and the vibration reduction of transformer structures is carried out from the aspects of vibration and noise transmission paths of transformer structures. Research on noise reduction technology is very limited;

[0004] (2) After the existing transformer is installed, although the bracket is used to fix it, there is still a certain vibration during the operation of the transformer, which produces noise and is not practical.
