Abstract

The utility model discloses a three-phase amorphous alloy three-dimensional iron core transformer. An iron core of the three-phase amorphous alloy three-dimensional iron core transformer is formed by three same single-phase iron cores which are arranged in a regular triangle three-dimensional shape. Each single-phase iron core is formed by continuous amorphous alloy strips in a winding mode. Due to the adoption of the technical scheme, the three-phase amorphous alloy three-dimensional iron core transformer has the advantages that core columns made of amorphous alloy are arranged in a three-dimensional equal-distance triangular array mode, materials are saved by 10% compared with the iron core produced in the prior art, raw materials are saved, consumption of the iron core is correspondingly reduced by about 10%, energy consumption is reduced, amorphous alloy strips are effectively prevented from loosening and dropping, and performance of the transformer is improved.

Description

The three-dimensional appendiron core transformer of three-phase amorphous alloy

Technical field:

The utility model relates to a kind of transformer, is specifically related to a kind of novel amorphous and Gionee body appendiron core transformer.

Background technology:

Present distribution transformer basically adopts cold-reduced silicon sheet to fold with iron core and forms, laminated core structure is owing to exist air-gap in the magnetic circuit, defective tightness between the silicon steel sheet, but also exist the high magnetic conduction direction of local area material and the magnetic circuit direction inconsistent, not only no-load loss is large to make iron core, and poor-performing.

Non-crystaline amorphous metal is to adopt rapid quench to solidify production technology, and its physical state shows as metallic atom and is unordered noncrystal arrangement, is more conducive to be magnetized and degaussing.This material is used for making transformer core, and the magnetization process of transformer is very easy to, and can greatly reduce the no-load loss of transformer, so non-crystaline amorphous metal is a kind of more energy-conservation material.

The most plane laminated core structure structural designs that adopt of existing distribution transformer, this structure causes A phase, C phase magnetic circuit longer, and B phase magnetic circuit is shorter, and the magnetic flux of three-phase equilibrium is during through unbalanced magnetic circuit, to cause the Three-Phase Transformer current imbalance, thereby affect electric property.

The utility model content:

For the problems referred to above, a kind of Three phase stereo amorphous alloy appendiron core transformer of special proposition, its concrete technical scheme is:

The three-dimensional appendiron core transformer of three-phase amorphous alloy, iron core is comprised 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 main bodys of iron core is symmetrical, so that no-load current also is symmetrical.Be respectively equipped with the ectonexine silicon steel sheet in the amorphous alloy strips outside and inboard, can effectively prevent the loose and disengaging of amorphous alloy strips, improved the performance of transformer.

Description of drawings:

The schematic top plan view of the three-dimensional appendiron core transformer of Fig. 1 three-phase amorphous alloy.

The single-phase iron core schematic diagram of the three-dimensional appendiron core transformer of Fig. 2 three-phase amorphous alloy.

Wherein: the coiled iron core of 1-amorphous alloy transformer; 2-single frame iron core

Embodiment:

With reference to Fig. 1, Fig. 2, the utility model, the i.e. coiled iron core 1 of amorphous alloy transformer, stem stem are three-dimensional to be arranged, and is put together by the single frame iron core 2 of the identical cross section of three shapes close to semicircle, and the stem stem cross section approaches circular after making amalgamation.

The outer contour of the stem stem cross section of single frame be some broken lines be formed by connecting near semicircular arc, the trailing wheel profile is a diameter line.

The single frame iron core be by the amorphous alloy film of some grades of different in width from inside to outside coiling form.

The utility model is because iron core is that non-crystaline amorphous metal rolls continuously, do not cut-off, there is not interface, the wire winding is on the circular iron core post, more can save no-load loss and the materials of saving non-crystaline amorphous metal than the amorphous transformer of supplying on the existing market, be a product of saving iron core raw material and electric energy loss.

Roll the iron core that is this type of, need special purpose machine tool, iron core needs colligation, clamping and annealing in installation process.

Above execution mode only is the preferred embodiments of the present invention; the invention is not restricted to above-described embodiment; for persons skilled in the art, any apparent change of under the prerequisite that does not deviate from the principle of the invention it being done all belongs to protection scope of the present invention.
