Iron core of dry type magnetic shielding electric reactor

Abstract

The invention discloses an iron core of a dry type magnetic shielding electric reactor. The iron core comprises an iron core body. The iron core body comprises an inner ring and an outer ring which are both of a cylindrical structure. An annular heat dissipation gas way is formed between the inner ring and the outer ring through supporting of a plurality of supporting strips. The thickness of the inner ring is smaller than the thickness of the outer ring. The height of the inner ring is larger than the height of the outer ring. End rings are arranged in the spaces between the end faces of the two sides of the outer ring and the end faces of the two sides of the inner ring respectively. The iron core is simple in structure and easy to manufacture and overcomes the defects of a traditional single structure, the structure arrangement of the inner ring and the outer ring is scientific and reasonable, and the use amount of electrical steel sheets for manufacturing iron core materials can be effectively decreased; meanwhile, heat dissipation is convenient, and the improvement of the overall performance of the magnetic shielding electric reactor is facilitated.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to an iron core of a dry-type magnetic shielding reactor. Background technique [0002] The dry-type magnetic shielding reactor is a new generation product developed on the basis of the dry-type air-core reactor. It plays the role of concentrating the magnetic force lines and reducing the outward divergence of the magnetic force lines of the air-core reactor. This kind of reactor not only has the advantages of the air-core reactor, but also has the function of magnetic flux leakage shielding, which can greatly reduce the magnetic field leakage of the reactor and the installation site. [0003] At present, most of the iron cores used in dry-type magnetic shielding reactors are single-ring hollow cylindrical structures. This single-structure iron core has the following disadvantages: on the one hand, as the capacity of the magnetic shielding reactor increases, the diameter of the ir...

AI Technical Summary

Problems solved by technology

This single-structure iron core has the following disadvantages: on the one hand, as the capacity of the magnetic shielding reactor increases, the diameter of the iron core used increases accordingly, and the electrical silicon steel sheet material used to make the iron core also increases, thereby increasing the magnetic shielding reactor. Production cost; on the other hand, the iron core is a single closed structure, and there is no corresponding heat dissipation channel, which makes it difficult to dissipate heat from the iron core, thereby reducing the overall performance of the magnetic shielding reactor
