Amorphous alloy transformer with three-dimensional antitorque clamp and iron core parallel independent distribution structure

Abstract

The invention relates to an amorphous alloy transformer with a three-dimensional antitorque clamp and an iron core parallel independent distribution structure. The amorphous alloy transformer comprises two pulling plates and an iron core group, and is characterized by also comprising an upper frame clamp component and a lower frame clamp component, wherein a side clamp component is connected between the upper end clamp component and the lower end clamp component; the tops of the pulling plates are connected with the inner side surface of an upper clamp component in the upper frame clamp component; the bottoms of the pulling plates are connected with the inner side surface of a lower clamp component in the lower frame clamp component; and a clearance is formed between the two pulling plates. The amorphous alloy transformer has the advantages that the structure is simple, the stressed state of the iron core in a product is greatly improved, the stressed distribution of the iron core is perfected, the no-load loss of the amorphous alloy transformer is relatively and greatly reduced, and the stability of an energy0saving index is greatly improved. At the same time, the high requirement on an assembling process in a product manufacturing process is reduced, so that the management of product manufacture can be reduced, and the yield of the product is improved to a relatively large extent.

Description

technical field [0001] The invention relates to the field of power transformers, in particular to an amorphous alloy transformer with three-dimensional torsion-resistant clamping and parallel independent distribution of cores. Background technique [0002] At present, in the domestic and international markets, the structural design of dry-type amorphous transformers is often based on the clamp fastening structure of traditional dry-type transformers, and the limit-type iron core pull plate structure is added to achieve both fastening and fastening of the transformer. Coil and core, and prevent the core from excessive force. This design structure takes into account and balances the contradictory requirements of the overall structural strength of the product and avoiding the force of the amorphous core, and can obtain the expected effect. It is a relatively appropriate structural scheme. But with the large-scale production of products, its shortcomings become more and more ob...

Problems solved by technology

When the iron core is clamped by the clamp as a whole, although the limit device determines the degree of clamping, the overall dimensional accuracy of the core itself is discrete, and the dimensions of the clamp and the limit device are also discrete, so after the product is asse...
