Transformer vibration damping device and using method thereof

Abstract

The invention relates to a transformer vibration damping device and a using method thereof, and belongs to the technical field of transformer equipment. The invention adopts the technical scheme that the transformer vibration damping device comprises rubber mats (1), raised rubber points (2), steel plates (3) and positioning holes (4); more than two layers of rubber mats are provided and are sequentially arranged from bottom to top; a plurality of raised rubber points are formed on the lower surface of each layer of rubber mat; except for the rubber mat on the uppermost layer, the upper surfaces of the rest of rubber mats are adhered to the steel plates of which an area is equal to that of the rubber mats; a thickness of each steel plate is smaller than that of each rubber mat; vibration damping layers are formed by the rubber mats adhered to the steel plates; and the positioning holes are formed on the rubber mat on the uppermost layer. The transformer vibration damping device and the using method thereof, which are disclosed by the invention, have the beneficial effects that the composite vibration damping device is adopted, is mounted at a position of an iron core cushioning foot at the bottom of a transformer, is positioned at a joint of a transformer body and an oil tank and is relatively large in deformation quantity in the using process; a damping effect is reinforced; vibration of an iron core is transferred to the bottom of the oil tank by the vibration damping device; and a vibration damping effect can be achieved better.

Description

technical field [0001] The invention relates to a transformer vibration damping device and an application method thereof, belonging to the technical field of transformer equipment. Background technique [0002] As substations are getting closer to residential areas and people's awareness of environmental protection is increasing, the noise problem of transformers has been highly valued by the power sector and transformer manufacturers. Transformer noise is one of the important technical parameters of the transformer, which is mainly generated by the vibration of the iron core, winding, oil tank (including magnetic shielding, etc.) and cooling device. The iron core, winding and oil tank (including magnetic shielding, etc.) are collectively referred to as the transformer body. The source of the noise of the transformer body is: (1) the vibration of the iron core caused by the magnetostriction of the silicon steel sheet; (2) the presence of (3) When there is a load current pas...

AI Technical Summary

Problems solved by technology

In the prior art, solid long rubber pads are usually used at the bottom of the iron core pads, and the thickness is generally more than 20mm. Due to the high hardness, the deformation and damping effect are limited, and the vibration reduction effect during the vibration process is general.
