Transformer iron core capable of reducing noise,

Abstract

The invention discloses a transformer iron core capable of reducing noise, include a connection column, A plurality of iron cores are movably arranged around the outer periphery of the connecting column, A plurality of mounting holes are arranged around the outer periphery of the connecting column, the iron core is fixedly installed with a plurality of mounting blocks on the side close to the connecting pillar, the mounting blocks are movably installed in the mounting holes, A win layer is movably arrange on that exterior of the iron core, A plurality of columns are fixedly installed inside the winding layer, A lay of flexible material is fixedly installed on that out part of the winding layer, The flexible material layer is all made of cellular foam material, the flexible material layer is fixedly installed with a film material layer outside, the film material layer is all made of lacquer cloth, the film material layer is all fixedly installed with a plate material layer outside, andthe plate material layer is all made of hard fiberboard. The sound absorbing cotton is filled between the mounting hole and the mounting block, so that the noise generated between the iron core and the connecting post can be reduced when the iron core vibrates.

Description

technical field The invention relates to the technical field of transformer iron cores, in particular to a transformer iron core capable of reducing noise. Background technique Amorphous alloy is a kind of ultra-rapid solidification. When the alloy is solidified, the atoms have no time to arrange and crystallize in an orderly manner. The obtained solid alloy has a long-range disordered structure. There are no crystalline grains and grain boundaries, which are called amorphous alloys. Iron cores made of amorphous alloys are used in many of our current machines and electrical equipment, and are widely used in the field of transformer technology due to their excellent corrosion resistance, wear resistance, and high strength; A traditional transformer core that can reduce noise has the following deficiencies; The noise of the amorphous alloy transformer is mainly generated by the amorphous alloy iron core. Due to the large magnetostriction of the amorphous alloy iron core, th...
