Abstract
The utility model relates to a kind of low-loss three phase three limb core lamination, belongs to technical field of transformer manufacturing.Technical scheme is: comprise stem (1), upper yoke (2) and lower yoke (3), upper yoke (2) and lower yoke (3) are formed by iron yoke silicon steel sheet (4) multistage stack, and stem is formed by stem silicon steel sheet (5) multistage stack; The sheet of described upper yoke (2) and lower yoke (3) iron at different levels yoke silicon steel sheet is wide, and the sheet that equal proportion is greater than stem (1) stem at different levels silicon steel sheet is wide; The sectional area of upper yoke (2) and lower yoke (3) is equal, is all greater than stem (1) sectional area, makes upper yoke and lower yoke magnetic is close diminishes, and effectively reduces the no-load loss of transformer.The sheet of upper yoke (2) and lower yoke (3) silicon steel sheet at different levels is wide is wide 1.2 times of the sheet of stem (1) silicon steel sheet at different levels.The beneficial effects of the utility model are: when not increasing load loss, effectively can reduce the no-load loss of transformer.
Description
Technical field
The utility model relates to a kind of low-loss three phase three limb core lamination, belongs to technical field of transformer manufacturing.
Background technology
Three phase three limb core is the support frame of transformer body, and this structure is made up of three stems and Double layer iron yoke.Background technology, in order to reduce the no-load loss of transformer, unilaterally reduces core-diameter during design, coil turn can be made to increase, will inevitably increase load loss.Under the prerequisite ensureing transformer superperformance, how effectively reducing the no-load loss of transformer when not increasing load loss, is the technical problem of this area faced by when developing low loss transformer.
Utility model content
The utility model object is to provide a kind of low-loss three phase three limb core lamination, when not increasing load loss, effectively can reduce the no-load loss of transformer, solves Problems existing in background technology.
The technical solution of the utility model is:
A kind of low-loss three phase three limb core lamination, comprise stem, upper yoke and lower yoke, upper yoke and lower yoke are formed by the multistage stack of iron yoke silicon steel sheet, and stem is formed by the multistage stack of stem silicon steel sheet; The sheet of described upper yoke and lower yoke iron at different levels yoke silicon steel sheet is wide, and the sheet that equal proportion is greater than stem stem at different levels silicon steel sheet is wide; The sectional area of upper yoke and lower yoke is equal, is all greater than heart column section and amasss, and makes upper yoke and lower yoke magnetic is close diminishes, and effectively reduces the no-load loss of transformer.
The sheet of upper yoke and lower yoke iron at different levels yoke silicon steel sheet is wide, wide 1.2 times of the sheet for stem stem at different levels silicon steel sheet, namely upper yoke and lower yoke iron at different levels yoke silicon steel blade wide, in the scope of stem silicon steel blade wide+20% at different levels, equal proportion strengthens.
The beneficial effects of the utility model are: when not increasing load loss, effectively can reduce the no-load loss of transformer.

Fig. 3 is the utility model Embodiment B-B cutaway view;
In figure: stem 1, upper yoke 2, lower yoke 3, iron yoke silicon steel sheet 4, stem silicon steel sheet 5.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
A kind of low-loss three phase three limb core lamination, comprise stem 1, upper yoke 2 and lower yoke 3, upper yoke 2 and lower yoke 3 are formed by the multistage stack of iron yoke silicon steel sheet 4, and stem is formed by the multistage stack of stem silicon steel sheet 5; The sheet of described upper yoke 2 and lower yoke 3 iron at different levels yoke silicon steel sheet is wide, and the sheet that equal proportion is greater than stem 1 stem at different levels silicon steel sheet is wide; The sectional area of upper yoke 2 and lower yoke 3 is equal, is all greater than stem 1 sectional area, makes upper yoke and lower yoke magnetic is close diminishes, and effectively reduces the no-load loss of transformer.
The sheet of upper yoke 2 and lower yoke 3 iron at different levels yoke silicon steel sheet is wide, wide 1.2 times of sheet for stem 1 stem at different levels silicon steel sheet, namely upper yoke and lower yoke iron at different levels yoke silicon steel blade wide, in the scope of stem stem silicon steel at different levels blade wide+20% equal proportion strengthen.
