Differential vibration reduction pad block

Abstract

The invention discloses a differential vibration reduction pad block, which is characterized in that a rubber rectangular plate block is provided with separated positioning holes along the length middle line of the plate block. The upper surface and the lower surface of the plate block are provided with convex points arranged in lines and rows, the convex points are in alternating arrangement, and have different heights and different sizes, the small convex points in alternating arrangement in each line and row are higher than medium convex points, and the medium convex points are higher than large convex points. The flexibility is gradually enhanced through the differential arrangement structure, so that the adaptation to the iron core matched vibration reduction in different specifications and the same model can be realized. In the operation process of an amorphous transformer, certain vibration is generated due to the iron core magnetic induction, and most of the vibration is absorbed by the soft differential vibration reduction block padded at the lower part, so that the vibration grade is greatly weakened. Since the vibration of the iron core is reduced, and the noise of the matched amorphous transformer is also obviously reduced. The differential vibration reduction pad block is applied to the matched amorphous transformer, and can also be applied to other electromechanical equipment having requirements on vibration reduction.

Description

technical field [0001] The invention relates to a vibration damping device, in particular to a rubber vibration damping pad, especially a differential vibration damping pad with a graded load-bearing structure. Background technique [0002] Amorphous transformer is a new type of energy-saving power switching equipment. Its operation quality has a number of assessment indicators. In addition to electrical performance, vibration indicators are also a very important assessment indicator. When the transformer is running, due to the magnetic induction, the built-in iron core is prone to vibration, and the vibration is accompanied by disturbing noise. Commercial amorphous transformers on the market have taken vibration reduction measures in their structures and achieved corresponding technical effects. But the vibration-damping pad used in the prior art is made of commodity rubber plate, and this kind of flat block only utilizes the inherent elasticity of the rubber material to d...

Problems solved by technology

In reality, there are many specifications of amorphous transformers, and the supporting cores and windings have different weights. The vibration damping pad made of a single rubber plate cannot meet the supporting requirements of transformers of various specifications.
