Abstract

The utility model relates to a kind of low-loss core lamination stacked structure, belongs to transformer technology field.Technical scheme is: comprise upper yoke (1), lower yoke (2), side iron yoke (3) and stem (4), stem (4) is positioned at center, upper yoke (1) is positioned at above stem, and lower yoke (2) is positioned at below stem, and two sides iron yoke (3) are positioned at stem both sides; The width of described upper yoke and lower yoke, is greater than the width of stem, and lamination stack becomes iron yoke and stem, and the lamination of stack iron yoke comprises trapezoidal lamination (5), and trapezoidal lamination (5) removes one jiao (6) on bottom line.The beneficial effects of the utility model are: increase iron yoke sectional area, reduce the magnetic flux density in iron yoke, and then reduce the no-load loss of transformer.

Description

A kind of low-loss core lamination stacked structure
Technical field
The utility model relates to a kind of low-loss core lamination stacked structure, belongs to transformer technology field.
Background technology
At present, the iron yoke of conventional transformer core is equal with stem width, and adopt the flap-type at different levels of core lamination wide, 45 ° of mitre stacks, the wedge angle size of stretching out during its stack is all identical.But when low loss transformer Core Design, general employing three phase three limb core form, can increase the magnetic flux density in iron yoke, and then increase the no-load loss of transformer.
Utility model content
The utility model object is to provide a kind of low-loss core lamination stacked structure, and iron yoke and stem adopt not equivalance to design, and increase iron yoke sectional area, reduce the magnetic flux density in iron yoke, and then reduce the no-load loss of transformer, and rational in infrastructure, solve the problems referred to above that background technology exists.
The technical solution of the utility model is: a kind of low-loss core lamination stacked structure, comprise upper yoke, lower yoke, side iron yoke and stem, stem is positioned at center, and upper yoke is positioned at above stem, lower yoke is positioned at below stem, and two side iron yokes are positioned at stem both sides; The width of described upper yoke and lower yoke, is greater than the width of stem, and lamination stack becomes iron yoke and stem, and the lamination of stack iron yoke comprises trapezoidal lamination, and trapezoidal lamination removes one jiao on bottom line.
Described trapezoidal lamination is isosceles trapezoid, and base angle is 45 degree, removes a jiao on bottom line.
The beneficial effects of the utility model are: increase iron yoke sectional area, reduce the magnetic flux density in iron yoke, and then reduce the no-load loss of transformer.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is that the trapezoidal lamination of the utility model removes one jiao of schematic diagram;
In figure: upper yoke 1, lower yoke 2, side iron yoke 3, stem 4, trapezoidal lamination 5, a jiao 6.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
A kind of low-loss core lamination stacked structure, comprise upper yoke 1, lower yoke 2, side iron yoke 3 and stem 4, stem 4 is positioned at center, and upper yoke 1 is positioned at above stem, and lower yoke 2 is positioned at below stem, and two side iron yokes 3 are positioned at stem both sides; The width of described upper yoke and lower yoke, is greater than the width of stem, and lamination stack becomes iron yoke and stem, and the lamination of stack iron yoke comprises trapezoidal lamination 5, and trapezoidal lamination 5 removes one jiao 6 on bottom line.
Described trapezoidal lamination 5 is isosceles trapezoid, and base angle is 45 degree, removes a jiao 6 on bottom line.
The core lamination of background technology is the wide 45 ° of mitre stacks of flap-type at different levels, and the wedge angle size of stretching out during its stack is all identical.The utility model iron core is when stack because at different levels sections yokes are wider than stem, and when employing 45 ° of mitre stacks, the wedge angle size that the every one-level of iron yoke is stretched out is all different, needs to chamfer.
