Abstract

The utility model relates to the technical field of transformers, in particular to an internal structure of an oval-shaped power transformer. The internal structure of the oval-shaped power transformer comprises wire plates, an upper iron yoke insulator and a lower iron yoke insulator. Vertical wire plates which are arranged in the shape of an oval vertically are arranged between the upper iron yoke insulator and the lower iron yoke insulator. The wire plates are arranged on the upper portions of the upper iron yoke insulator and the lower iron yoke insulator. The vertical wire plates are fixed through platens, and interval partition plates are arranged between each two vertical wire plate for insulation. Due to design of oval-shaped sections of iron cores, center and angle weight are lowered, and weight of the iron cores and no-load loss are reduced. Because the sections of the iron cores are changed into oval shapes, circumference of windings, weight of wires and load loss increase slightly. Thus effects of energy and materials conservation are achieved.

Description

A kind of elliptic power transformer internal structure
Technical field
The utility model relates to the transformer technology field, specifically a kind of elliptic power transformer internal structure.
Background technology
The energy consumption of transformer self mainly contains two kinds, a kind of is the no-load loss that iron core produces, another kind mainly is the load loss that has wire to produce, although no-load loss is little more a lot of than nominal load loss, but as long as product hanging net operation, no matter load, no-load loss always exists, especially in transformer underloading situation, the proportion that no-load loss accounts for total losses is very large, therefore reduces the main trend that no-load loss is the transformer technology development, the product of traditional circular section core transformer design, material cost is high, and energy-saving effect is not obvious.
Therefore, design for above situation a more reasonable, manufacturing cost is lower and can reduce the novel transformer internal structure of no-load power consumption, inventor's problem to be solved just.
Summary of the invention
The purpose of this utility model provides a kind of elliptic power transformer internal structure, and it is simple in structure, and is easy to use, and its design is more reasonable, manufacturing cost is lower and can reduce no-load power consumption, has extraordinary practical value.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of elliptic power transformer internal structure, comprise line plate, upper yoke insulation, lower yoke insulation, described in the middle of upper yoke insulation and lower yoke insulation, being provided with vertically and vertical line plate that ovalize is arranged, in upper yoke insulation and lower yoke insulation top wired plate is set also, the vertical line plate is fixed by pressing plate, isolates by phase partition between the vertical line plate.
The beneficial effects of the utility model are:
1, by adopting the elliptic cross-section core design, reduced center and angle and weighed, alleviated the weight of iron core, reduced no-load loss, core section makes ellipse into, and the girth of winding, wire weight and load loss have a little to increase, reached energy-conservation, material-saving effect.

Fig. 2 is the utility model plan structure schematic diagram.
Description of reference numerals: 1-line plate; The insulation of 2-upper yoke; 3-vertical line plate; The insulation of 4-lower yoke; The 5-pressing plate; The 6-phase partition.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model, should understand, these embodiment only are used for explanation the utility model and are not used in restriction scope of the present utility model, should understand in addition, after the content of having read the utility model instruction, those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values drop on application appended claims limited range equally.
Such as Fig. 1, shown in 2, the utility model structural representation and plan structure schematic diagram, comprise line plate 1, upper yoke insulation 2, lower yoke insulation 4, described in the middle of upper yoke insulation 2 and lower yoke insulation 4, being provided with vertically and vertical line plate 3 that ovalize is arranged, on upper yoke insulation 2 and lower yoke 4 tops of insulating wired plate 1 is set also, vertical line plate 3 is fixed by pressing plate 5, between vertical line plate 3, isolate by phase partition 6, by adopting the elliptic cross-section core design, it is heavy to have reduced center and angle, alleviated the weight of iron core, reduced no-load loss, core section makes ellipse into, the girth of winding, wire weight and load loss have a little increase, have reached energy-conservation, material-saving effect.
