Transformer, transformer box and vibration damping device for transformer box

Abstract

The invention relates to a transformer, a transformer box and a vibration damping device for the transformer box. The vibration damping device is arranged on the outside of the box, and the vibration damping device includes: The connected fixing piece, a plurality of boards arranged coaxially under the fixing piece, first elastic connecting pieces respectively arranged between the fixing piece and the boards and between the boards, and the boards and the box The second elastic connecting piece arranged between the bodies. The present invention overcomes the defects of the prior art, adopts the shell and the fixing parts, plates and elastic connectors arranged in it, and constrains the in-plane vibration of the box wall, thereby greatly reducing the noise generated by the vibration of the box wall, and strives to realize the low voltage of the transformer. Noise-based operation, effectively solve the problem of excessive noise in substations, and build an environment-friendly power transmission and transformation project.

Description

technical field [0001] The invention relates to a transformer damping technology, in particular to a transformer, a transformer box and a vibration damping device for the transformer box. Background technique [0002] With the rapid development of urban construction and the continuous increase of social electricity consumption, many substations have gradually penetrated into densely populated areas, and there are more and more substations in urban areas. The vibration and noise problems of substations have gradually become the focus of social attention. [0003] Large oil-immersed transformers are the main source of noise in substations, and there are many ways to reduce transformer noise. Noise reduction measures based on transformer core and winding vibration control technology have limited improvement in actual effect, and are subject to varying degrees of restrictions in terms of material properties, product design, production technology, and cost. There is a large contr...
