Abstract
The invention relates to a double-stage type D-shaped yoke structure of a converter transformer, and belongs to the technical field of converter transformer equipment. According to the technical scheme, a double-stage type D-shaped yoke (1) of the converter transformer is formed into a whole by upper half part core laminations (2) and lower half part core laminations (3) and is of a D shape, the upper half part core laminations (2) are of a stepped multi-stage ranking structure, and the lower half part core laminations (3) are of a double-pole ranking structure. The double-stage type D-shaped yoke structure of the converter transformer has the advantages that core magnetic requirements are met, raw materials are saved, and iron loss consumption in the operating process is reduced; magnetic shielding is increased, and therefore reliability of the converter transformer is improved, and the structure is simple.
Description
Technical field
The present invention relates to a kind of converter transformer stage type " D " type yoke structure, belong to converter transformer equipment technical field.
Background technology
At present, what in common converter transformer, adopt is multistage ellipse yoke structure, and its implementation method is that iron yoke cross section is less than post iron cross section, make its levels inferior and stem at different levels inferior corresponding, must make multistage elliptic cross-section.This kind of iron yoke structure is complicated, and raw material consumption is large, and after operation, iron loss consumption is large.
Summary of the invention
The object of the invention is to provide a kind of converter transformer stage type " D " type yoke structure, and while reducing operation, iron loss consumes, and increases magnetic screen, improves the reliability of converter transformer, solves the problem existing in background technology.
Technical scheme of the present invention is:
A kind of converter transformer stage type " D " type yoke structure, converter transformer stage type " D " type yoke is integrally formed by first half core lamination and Lower Half core lamination, be " D " type, the stepped multistage arrangement architecture of described first half core lamination, described Lower Half core lamination is bipolar arrangement structure.
Converter transformer stage type " D " type yoke is symmetrical structure.
The invention has the beneficial effects as follows: when meeting electromagnetism requirement unshakable in one's determination, saved raw material, the iron loss consumption while having reduced operation, increases magnetic screen, has improved the reliability of converter transformer, simple in structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: converter transformer stage type " D " type yoke 1, first half core lamination 2, Lower Half core lamination 3.
Embodiment
Below in conjunction with accompanying drawing, by example, the invention will be further described.
With reference to accompanying drawing 1, a kind of converter transformer stage type " D " type yoke structure, converter transformer stage type " D " type yoke 1 is integrally formed by first half core lamination 2 and Lower Half core lamination 3, be " D " type, the stepped multistage arrangement architecture of described first half core lamination 2, described Lower Half core lamination 3 is bipolar arrangement structure, and converter transformer stage type " D " type yoke 1 is symmetrical structure.
Converter transformer stage type " D " type yoke structure is to meet under the prerequisite of electromagnetism requirement at iron yoke sectional area, changes that original iron yoke structure shape realizes.Saved raw material, the iron loss consumption while having reduced operation, structurally provides space for product increases the reliability that magnetic screen improves transformer.
Claims (2)
1. a converter transformer stage type " D " type yoke structure, it is characterized in that converter transformer stage type " D " type yoke (1) is integrally formed by first half core lamination (2) and Lower Half core lamination (3), be " D " type, the stepped multistage arrangement architecture of described first half core lamination (2), described Lower Half core lamination (3) is bipolar arrangement structure.
2. converter transformer stage type according to claim 1 " D " type yoke structure, is characterized in that converter transformer stage type " D " type yoke (1) is symmetrical structure.
