Abstract

The utility model relates to an iron core structure of an amorphous alloy transformer. An iron core consists of three identical single-phase iron cores which are in equilateral triangle three-dimensional distribution; and each single-phase iron core is formed by winding continuous amorphous alloy strips. In the utility model, the three single-phase iron cores are in equilateral triangle distribution, the magnetic circuits of three column bodies of the iron cores are symmetrically distributed, so that the no-load current is symmetrically distributed. Inner and outer-layer silicon steel sheets are respectively arranged at the innermost and outermost layers of the amorphous alloy strips, so that the amorphous alloy strips are prevented from being loosened and separated, and the performance of the transformer is improved.

Description

A kind of core structure of amorphous alloy transformer

Technical field

The utility model belongs to the transformer technology field, is specifically related to a kind of core structure of amorphous alloy transformer.

Background technology

Amorphous alloy transformer is a kind of low-loss energy-economic transformer of excellence, and it utilizes amorphous alloy material to replace silicon steel sheet to process iron core, and its feature is that no-load loss is low little with no-load current, has therefore obtained increasing attention.At present, the iron core of amorphous alloy transformer adopts the plane laminated structure mostly, and this structure causes A phase, C phase magnetic circuit longer; B phase magnetic circuit is shorter; The magnetic flux of three-phase equilibrium will cause the transformer three-phase current unbalance, thereby influence electric property during through unbalanced magnetic circuit.

The utility model content

The purpose of the utility model is to solve the above-mentioned technical problem that exists in the prior art, and a kind of core structure of amorphous alloy transformer is provided.

To achieve these goals, the technical scheme of the utility model employing is following:

The core structure of amorphous alloy transformer, this iron core is made up of three identical single-phase iron cores, and three single-phase iron cores are the equilateral triangle stereo structure to be arranged, and described each single-phase iron core is reeled by continuous amorphous alloy strips and is formed.

Each single-phase iron core is provided with the internal layer silicon steel sheet in innermost layer amorphous alloy strips inboard, is provided with outer silicon steel sheet in the outermost layer amorphous alloy strips outside.

Three single-phase iron cores are triangular arranged in the utility model, and the magnetic circuit of three cylinders of iron core is symmetrically distributed, and make that no-load current also is to be symmetrically distributed, and makes no-load current also be symmetrically distributed.Be respectively equipped with inside and outside layer silicon steel sheet with outermost in that amorphous alloy strips is the most inboard, can effectively prevent the loose and disengaging of amorphous alloy strips, improved the performance of transformer.
