Low-noise transformer

Abstract

The invention discloses a low-noise transformer, and belongs to the field of power transformation equipment. The low-noise transformer comprises a box body. A plurality of radiators are arranged on the two sides of the box body. The radiators are communicated with the interior of the box body through guiding pipes. Each radiator comprises a metal shell separated from the box body. A vibration reduction pad and a heat insulation layer are arranged between each metal shell and the box body. The vibration reduction pads make contact with the box body. The heat insulation layers make contact with the metal shells. A hydraulic rod is arranged at the bottom of the box body. The box body and an external object are fixed through the hydraulic rod. The surface of the box body is covered with a noise reduction layer. The noise generated by the transformer is lowered on the whole due to the fact that the vibration reduction or noise reduction components are additionally arranged at the multiple positions.

Description

technical field [0001] The invention relates to the field of power transformation equipment, in particular to a low-noise transformer. Background technique [0002] With the development of urbanization and the shortage of land resources, a large number of transformers are used in business centers, office buildings, residential quarters and other places where people work and live, and then frequently cause complaints about excessive noise. Therefore, how to control the noise during transformer operation has become a focus of attention of the State Grid Department. [0003] Vibration is the source of noise, and transformer noise is generated by the magnetostriction of the iron core and propagates outward through the objects connected to it. One is the pad between the transformer body and the oil tank, and the other is the insulating oil between the transformer body and the oil tank. In the prior art, the vibration reduction and noise reduction technology for the iron core ha...

AI Technical Summary

Problems solved by technology

In the prior art, the vibration reduction and noise reduction technology for the iron core has a general effect, so it is particularly important to block the outward transmission of the vibration and noise of the transformer iron core

[0004] The existing technologies, such as the Chinese patent application number 201220447315 and the Chinese patent application number 201320356540, etc., although disclose the way to reduce transformer noise, are not suitable for oil-immersed transformers or have low noise reduction effect
