Description
Technical field
The utility model relates to a kind of step lapped iron core structures, belong to technical field of transformer equipment.
Background technique
As concern of the people to energy consumption, environmental protection is higher and higher, while between major transformer production producer
It is increasingly competitive, developing one kind there is an urgent need to transformer manufacturing field can reduce manufacturing cost, while function admirable
Core structure.
The conventional structure of existing transformer core is circle, the section of iron yoke and stem phase for the section of stem and iron yoke
Together, this is resulted in under-utilized in transformer core short transverse, causes the height of transformer coil and fuel tank to get higher, to make
Transformer whole height is got higher, and increases manufacturing cost.
Utility model content
The utility model aim is to provide a kind of step lapped iron core structure, the case where guaranteeing iron core effective sectional area
Under, it can be effectively reduced the height of transformer core, and then reduce transformer whole height, solved present in background technique
Problem.
The technical solution of the utility model is: a kind of step lapped iron core structure, comprising pulling plate, pulling plate insulation, stem,
Iron yoke, folder, stem oil duct and iron yoke oil duct, three stem parallel arrangements, the both ends of three stems are respectively equipped with an iron yoke,
The iron yoke and stem are fixed together by folder and pulling plate, and pulling plate is equipped between pulling plate and stem and is insulated, the stem is more
The cylindrical structure that is superimposed as of grade lamination is equipped with stem oil duct between lamination, and the iron yoke is the cross that two-stage lamination is superimposed as
Square structure, the section of cross square structure are the rectangular of quadrangle unfilled corner, and unfilled corner is small rectangle, and iron yoke oil is equipped between lamination
Road.
Lamination in the stem and iron yoke is made of electrical steel strip superposition.
The two-stage lamination of the iron yoke is divided into main lamination and secondary lamination, and the thickness of main lamination is secondary lamination thickness
2.7 times.
Lamination in the stem is ten Pyatyis, and ten Pyatyi laminations successively decrease from centre to two hem width degrees, make stem section at
Circular configuration.
The width of the iron yoke is smaller than the diameter of stem by 10%.
It is stepping overlapped form between the stem and iron yoke.
Using the utility model, stem is the multistage lamination to successively decrease from centre to two hem width degrees, and section is circle；Iron yoke
Only two-stage lamination, section are that cross is rectangular, and the width of iron yoke is smaller than the diameter of stem by 10%, because iron yoke is that cross is rectangular
Structure, therefore, though iron yoke width is narrow, sectional area is more slightly larger than stem, in this way in the case where guaranteeing iron core effective sectional area, has
The height of transformer core is reduced to effect, and then reduces the height of transformer coil and fuel tank.
The beneficial effects of the utility model are: iron core stack is simple, it is easy to operate.In the feelings for guaranteeing iron core effective sectional area
Under condition, it can be effectively reduced the height of transformer core, and then the height and transformer that reduce transformer coil and fuel tank are whole
Body height, can better materials saving.

Fig. 1 is the main view of the utility model；
Fig. 2 is that the utility model stem and iron yoke lamination overlap schematic diagram；
Fig. 3 is the sectional view of the utility model stem；
Fig. 4 is the sectional view of the utility model iron yoke；
In figure: electrical steel strip 1, pulling plate 2, pulling plate insulation 3, stem 4, iron yoke 5, folder 6, lamination 7, stem oil duct 8, iron yoke
Oil duct 9, main lamination 10, secondary lamination 11.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1 ~ 4, a kind of step lapped iron core structure includes pulling plate 2, pulling plate insulation 3, stem 4, iron yoke 5, folder
Part 6, stem oil duct 8 and iron yoke oil duct 9, three stems 4 are arranged in parallel, and the both ends of three stems 4 are respectively equipped with an iron yoke 5,
The iron yoke 5 and stem 4 are fixed together by folder 6 and pulling plate 2, and pulling plate insulation 3, the core are equipped between pulling plate 2 and stem 4
Column 4 is the cylindrical structure that multistage lamination is superimposed as, and stem oil duct 8 is equipped between lamination 7, and the iron yoke 5 is two-stage lamination stack
The cross square structure of addition, the section of cross square structure are the rectangular of quadrangle unfilled corner, and unfilled corner is small rectangle, are set between lamination
There is iron yoke oil duct 9.
Specific embodiment:
In the present embodiment, as shown in attached drawing 1,2, the lamination in stem 4 and iron yoke 5 is made of the superposition of electrical steel strip 1, is folded
Piece uses six grades of stepping overlapping mode stacks, and six grades of stepping (I, II, III, IV, V, VI) lap side seams are staggered respectively, to reduce
Magnetic resistance reduces loss.
Referring to attached drawing 3, stem 4 is that ten Pyatyi laminations are formed by stacking, and ten Pyatyi laminations successively decrease from centre to two hem width degrees, make
Stem sectional area is circular configuration, and stem oil duct 8 is arranged among lamination, to radiate.
Referring to attached drawing 4, iron yoke 5 is that two-stage lamination is formed by stacking cross square structure, and iron yoke oil is arranged among lamination
Road 9, to radiate, two-stage lamination is divided into main lamination and secondary lamination, and wherein the thickness of main lamination is the 2.7 of secondary lamination
Times, the thickness of main lamination accounts for the 72% of 5 overall thickness of iron yoke, the sectional area accounting of main lamination 10 is increased, to improve iron
The magnetic flux of core, while secondary lamination 11 only has level-one, both sides are symmetrical, make iron core stack simple in this way, easy to operate.
The width of iron yoke is smaller than the diameter of stem by 10%, because iron yoke 5 be cross square structure, though therefore 5 width of iron yoke it is narrow,
But sectional area is more slightly larger than stem 4, so that the effective sectional area of iron yoke 5 is greater than the effective sectional area of stem, reduces the height of iron core
Degree significantly reduces the height of transformer core in the case where guaranteeing iron core effective sectional area in this way, and then reduces transformation
The height of device coil and fuel tank.
Between stem 4 and iron yoke 5 every grade all by stepping overlapped form, overlap the lamination of different in width mutually.Cause
Width gap is larger, therefore needs to cut the wedge angle for stretching out iron yoke 5 or stem 4.
