Abstract
The utility model relates to a material-saving iron core structure of a transformer. The material-saving iron core structure of the transformer comprises N grade iron core units which are sequentially stacked up. A middle position iron core unit of the N grade iron core units is the biggest grade iron core unit, the silicon-steel sheet size of the biggest grade iron core unit is the biggest, the sizes of the all-grade iron core units located on the upper and lower sides of the biggest grade iron core unit sequentially and symmetrically shrink, the silicon-steel sheet sizes of the same grade iron core unit are the same, each grade iron core unit comprises at least a group of silicon-steel sheets, each group of silicon-steel sheets are formed by a plurality of silicon-steel sheets in a stacking up mode, and the horizontal section of the iron core structure is waist-circle-shaped. According to the material-saving iron core structure of the transformer, the horizontal section of the iron core of the transformer is waist-circle-shaped, materials for the iron core of the transformer are saved, and production cost of the iron core of the transformer is lowered.
Description
Technical field
The utility model relates to transformer part manufacturing technology field, relates in particular to a kind of core structure of material saving transformer.
Background technology
Transformer iron-core structure comprises the center pillar in the middle of being positioned at, left other post, right other post, upper yoke and lower yoke in the prior art, center pillar, left other post, right other post, upper yoke and lower yoke include the N level iron core unit that stacks successively, and the iron core unit at different levels of the center pillar of same core structure, left other post, right other post, upper yoke and lower yoke to stack mode identical.The iron core unit that is positioned at N level iron core unit centre position is the maximum level iron core unit, the silicon steel sheet size is maximum in the maximum level iron core unit, be positioned at the maximum level iron core unit up and down the iron core unit sizes at different levels of both sides dwindle gradually symmetrically successively, silicon steel sheet in the iron core unit at the same level is measure-alike, every grade of iron core unit includes at least one group of silicon steel sheet, and every group of silicon steel sheet formed by several pieces silicon steel sheet stacks.At present, the core structure that center pillar, left other post, right other post, upper yoke and lower yoke are positive circular cross section is referring to Fig. 1.Adopt this traditional core structure, consumptive material is apparent in view, and during production in enormous quantities, cost is also high.
Summary of the invention
Technical problem to be solved in the utility model is the large problem of core structure consumable quantity for existing transformer, and the core structure of the few material saving transformer of consumable material is provided.
For addressing the above problem, the technical solution of the utility model is:
A kind of core structure of material saving transformer, comprise the N level iron core unit that stacks successively, the iron core unit in the described N of being positioned at level iron core unit centre position is the maximum level iron core unit, the silicon steel sheet size is maximum in the maximum level iron core unit, be positioned at the maximum level iron core unit up and down the iron core unit sizes at different levels of both sides dwindle gradually symmetrically successively, silicon steel sheet in the iron core unit at the same level is measure-alike, every grade of iron core unit includes at least one group of silicon steel sheet, every group of silicon steel sheet formed by several pieces silicon steel sheet stacks, and the cross section of described core structure is oval shape.
Preferably, the silicon steel sheet group number of described maximum level iron core unit be the secondary iron core unit silicon steel sheet group number adjacent with the maximum level iron core unit 2-3 doubly.
Be compared to existing transformer iron-core structure, the cross section that the core structure of material saving transformer of the present utility model improves transformer core is oval shape, has saved the material of transformer core, has reduced the production cost of transformer core.
Description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of transformer iron-core structure in the prior art.
Fig. 2 is the cross-sectional structure schematic diagram of the core structure of the utility model material saving transformer.
Embodiment
Further describe the utility model below in conjunction with drawings and Examples, but protection range of the present utility model is not limited to this.
With reference to Fig. 2, the core structure of material saving transformer of the present utility model comprises center pillar, left other post, right other post, upper yoke and lower yoke, center pillar, left other post, right other post, upper yoke and lower yoke include the N level iron core unit that stacks successively, and the iron core unit at different levels of the center pillar of same core structure, left other post, right other post, upper yoke and lower yoke to stack mode identical.The iron core unit in the described N of being positioned at level iron core unit centre position is maximum level iron core unit 1, and the iron core unit adjacent with maximum level iron core unit 1 is secondary iron core unit 2.The silicon steel sheet size is maximum in the maximum level iron core unit 1, be positioned at the maximum level iron core unit about in the of 1 the iron core unit sizes at different levels of both sides dwindle gradually symmetrically successively, silicon steel sheet in the iron core unit at the same level is measure-alike, every grade of iron core unit includes at least one group of silicon steel sheet, every group of silicon steel sheet formed by several pieces silicon steel sheet stacks, and the cross section of described core structure is oval shape.The silicon steel sheet group number of maximum level iron core unit 1 be the secondary iron core unit 2 adjacent with maximum level iron core unit 1 silicon steel sheet group number 2-3 doubly.The utility model is the silicon steel sheet group number that has increased the maximum level iron core unit of original positive circular iron core structure, reduced the silicon steel sheet group number of other iron core unit at different levels, make the final cross section of core structure present oval shape, after adopting this structure, save the material of transformer core, reduced the production cost of transformer core.
Claims (2)
1. the core structure of a material saving transformer, comprise the N level iron core unit that stacks successively, the iron core unit in the described N of being positioned at level iron core unit centre position is the maximum level iron core unit, the silicon steel sheet size is maximum in the maximum level iron core unit, be positioned at the maximum level iron core unit up and down the iron core unit sizes at different levels of both sides dwindle gradually symmetrically successively, silicon steel sheet in the iron core unit at the same level is measure-alike, every grade of iron core unit includes at least one group of silicon steel sheet, every group of silicon steel sheet formed by several pieces silicon steel sheet stacks, it is characterized in that the cross section of described core structure is oval shape.
2. the core structure of described material saving transformer according to claim 1 is characterized in that, the silicon steel sheet group number of described maximum level iron core unit be the secondary iron core unit silicon steel sheet group number adjacent with the maximum level iron core unit 2-3 doubly.
