Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 , figure 2 , image 3 As shown, a noise-reducing amorphous alloy three-dimensional wound iron core is composed of three single-frame iron cores 1, and each single-frame iron core 1 is rolled into a certain thickness by multi-layer amorphous alloy strips, according to the thickness It is divided into several levels; a skeleton 2 is arranged on the single-frame iron core 1 .

[0015] Such as figure 2 As shown, when rolling a single-frame iron core, set the frame 2 at the first stage and the last stage; or set the frame 2 at the first stage, or set the frame 2 at the last stage

[0016] It is also possible to set a skeleton between certain adjacent levels in the single frame.

[0017] The material of the frame 2 can be magnetically permeable or non-magnetically permeable.

[0018] The stress of the single-frame iron core 1 is supported by t...

Abstract

The invention discloses an amorphous alloy three-dimensional rolled iron core capable of reducing noise and belongs to the field of electrical devices. The amorphous alloy three-dimensional rolled iron core is composed of three single-frame iron cores. Each single-frame iron core is formed by rolling a plurality of layers of amorphous alloy strip materials and divided into a plurality of levels according to the thickness. The amorphous alloy three-dimensional rolled iron core is characterized in that a frame is arranged on the single-frame iron core. The single-frame iron core is supported by the frame, the iron core is prevented from bearing self-stress of suspension, and noise caused by self-stress of the amorphous alloy three-dimensional rolled iron core is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and specifically refers to a method for reducing the noise of an amorphous alloy three-dimensional wound iron core. Background technique [0002] Transformers with amorphous alloy cores have been widely used because of their remarkable energy-saving and environmental protection features. At present, there are many kinds of amorphous alloy cores on the market, mainly including the following structures: single-phase single-frame, three-phase three-frame three-column, three-phase four-frame five-column, three-dimensional coiled core and so on. The common advantage of different types of amorphous alloy cores is low loss, but the disadvantage is high noise. [0003] Amorphous alloy three-dimensional wound iron core is a new type of iron core. Like other forms of amorphous alloy iron core, it is made of amorphous alloy strip with soft magnetic properties. Amorphous alloy strips have the ch...
