Sound attenuation clamping piece of amorphous alloy transformer

Abstract

The invention discloses a sound attenuation clamping piece of an amorphous alloy transformer, and belongs to the technical field of a transformer clamping piece. The sound attenuation clamping piece comprises an upper clamping piece (1) and a lower clamping piece (2), wherein the lower clamping piece (2) is matched with the upper clamping piece (1), the upper clamping piece (1) comprises a cover plate (11), first sound attenuation array holes (111) and first installation holes (112) are formed in the cover plate(11), the lower clamping piece (2) comprises a lower bottom plate (21) and second sound attenuation array holes (211), and the second sound attenuation array holes (211) are formed in the lower bottom plate (21). In the sound attenuation clamping piece of the amorphous alloy transformer, the first sound attenuation array holes and the second sound attenuation array holes are respectively formed in the upper clamping piece and the lower clamping piece, the resonance of an iron core and a winding of the amorphous alloy transformer can be effectively damaged by the first sound attenuation array holes and the second sound attenuation array holes, so that the noise of the amorphous alloy transformer is reduced, and the noise pollution generated by the amorphous alloy transformer on a surrounding environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of transformer clips, and more specifically relates to a sound-absorbing clip for an amorphous alloy transformer. Background technique [0002] There are two kinds of materials that people come into contact with every day: one is crystalline material and the other is amorphous material. The so-called crystalline material refers to the arrangement of atoms inside the material follows certain rules. On the contrary, if the internal atomic arrangement is in an irregular state, it is an amorphous material. In general metals, the internal atomic arrangement is orderly, and they are all crystalline materials. Scientists have discovered that after the metal is melted, the internal atoms are in an active state. Once the metal starts to cool, the atoms will gradually arrange in an orderly manner according to a certain crystal state as the temperature drops, forming a crystal. If the cooling process is fast, the at...

Problems solved by technology

[0005] But CN205845654U disclosed a kind of body clip structure of amorphous alloy transformer also has the following deficiencies: the clip reduces the noise produced by the vibration of the transformer when it is running by wrapping the iron core as a whole, and the magnetic domain expansion and contraction ratio of amorphous alloy material is higher than that of silicon steel. The sheet is much larger, 7 to 8 times that of the silica gel sheet, which directly affects the noise of the amorphous alloy transformer. The noise easily penetrates the clamp, and the noise reduction effect is not obvious.
