Transformer, transformer case and vibration damping device for transformer case

Abstract

The invention relates to a transformer, a transformer case and a vibration damping device for the transformer case. The vibration damping device is installed outside the case; the vibration damping device comprises: a fixing member for connecting to the outer side of the case; and a plurality of plates coaxially disposed below the fixing member; a first elastic connecting member disposed between the fixing member and the plate block and between the plate blocks, and a second elastic connecting member disposed between the plate block and the case. The present invention overcomes the deficiencies of the prior art by employing a housing and fixing members, plates and elastic connecting members disposed therein. By restraining the in-plane vibration of the box wall, the noise generated by thevibration of the box wall is greatly reduced, and the low-noise operation of the transformer is to realize and the problem of substation noise exceeding the standard is effectively solved, and the environment-friendly transmission and transformation project is constructed.

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...
