Abstract
The invention relates to a bevel stacked triangular iron core structure, which belongs to the technical field of power transmission and distribution equipment and is applicable to a transformer or a reactor. The bevel stacked triangular iron core structure is characterized in that three iron core columns in a triangle and with approximately circular sectional areas are connected through three upper yoke insertion sheets and three lower yoke insertion sheets with approximately semicircular sectional areas and folded obtuse angles at two ends to form a closed three-dimensional triangular magnetic circuit; a transformer iron core with the structure has the advantages of completely symmetrical three-phase magnetic circuits, shorter magnetic circuits, smaller volume and lower material consumption, more silicon steel sheet material saving and great reduction in no-load current and no-load loss, and has an efficient, energy-saving and environment-friendly transformer iron core structure; and the structure does not need to increase new equipment, can be realized by using the processing equipment for a conventional planar stacked iron core, and overcomes the defects of high equipment investment, coil winding inconvenience, waste of silicon steel sheets and the like of a triangular coiled iron core.
Description
Affiliated technical field
The present invention relates to a kind of bevel stacked triangular iron core structure, belong to the power transmission and distribution equipment technical field, be applicable to transformer or reactor.
Background technology
Three-dimensional iron core of triangle and conventional plane iron core that tradition is conventional, the length of a film that the three-dimensional iron core shortcoming of conventional triangle is processing is unequal, the machining accuracy height, difficulty of processing is big, and seam is big.The shortcoming of plane iron core embodies mainly that material is many, and loss is big, and no-load current is big.The core structure of three-phase transformer mostly is planar alignment silicon steel sheet closed assembly or rolls and forms, and the iron core of planar alignment silicon steel sheet closed assembly structure comes with some shortcomings: the utilance of silicon steel sheet is low, and consumptive material is many, and volume is big; Popular in recent years three-dimensional iron core, though have the low and little advantage of noise of no-load loss, but still exist the strictness of silicon steel sheet quality requirement, the silicon steel material utilance is low, the efficient that iron core is made is low, and needs to drop into special equipment, deficiencies such as coil winding inconvenience.
Summary of the invention
The present invention provides a kind of bevel stacked triangular iron core structure in order to solve the deficiency of various core structures described above.
A kind of bevel stacked triangular iron core structure of the present invention is made up of three duplicate stem stems and six duplicate yokes.Three stem stems are equilateral triangle to be arranged, each iron core column forms by the silicon steel sheet sign indicating number of multistage different in width is folded, the whole cross section sub-circular of iron core column.One or several parallelogram of the wide formation of the every A-class picture of iron core column with same parallelogram grafting yoke iron slice equal in length, has reduced difficulty of processing; Yoke is folded into the folded sign indicating number in obtuse angle by the section of the silicon steel sheet of multistage different in width and forms, the cross section approximate half-circular of yoke, and two ends are plugged on three iron core column, form closed 3-D triangle magnetic circuit; The yoke shape end that assembles is to be a triangle in the middle of the straight line.The transformer core of this kind structure, three-phase magnetic circuit be symmetry fully, and magnetic circuit is short, and volume is little, and consumptive material is few, saves silicon steel material, and no-load current and no-load loss descend greatly, are a kind of transformer fe cored structures of high-efficient energy-saving environment friendly.
Technical scheme
The technical solution adopted for the present invention to solve the technical problems is: the three-phase stem stem is equilateral triangle to be arranged, each iron core column forms its cross section sub-circular by the silicon steel sheet sign indicating number of multistage different in width is folded; One or several parallelogram of the wide formation of the every A-class picture of iron core column is with same parallelogram grafting yoke iron slice equal in length.Yoke is folded into the folded sign indicating number in obtuse angle by the section of the silicon steel sheet of multistage different in width and forms, the cross section approximate half-circular of yoke, two ends are plugged on three iron core column, form closed 3-D triangle magnetic circuit, and the yoke shape end that assembles is to be a triangle in the middle of the straight line.The slice length of yoke is made up of arc length and length of straigh line, its arc radius is determined by the folded thick and mould arc radius calculating of iron core, length of straigh line depends on that phase spacing (A) and sheet at different levels are wide, in assembling during yoke, make the lamination that is inserted into two yokes parts between the column type that is in line; Iron core column and yoke are through mitre or after directly stitching closed assembly, this core structure makes that the suit isoplanar iron core of high-voltage coil and low-voltage coil is equally flexible.
Beneficial effect of the present invention
This employing 3-D triangle is arranged the iron core of the structure of closed assembly, and volume is little, and consumptive material is few, and the silicon steel material utilance is up to more than 99%, and its cost reduces about 10% than the iron core of conventional planar alignment silicon steel sheet closed assembly structure, save the silicon steel sheet cost; No-load current and no-load loss descend greatly on performance, and manufacturer need not increase new equipment, utilize the process equipment of conventional planar alignment closed assembly iron core just can realize, are a kind of transformer or core of reactor structures of high-efficient energy-saving environment friendly.
Embodiment
At first according to the computational methods of plane three-phase transformer or core of reactor, calculate the iron core column cross-sectional area (D) that will make stacked angle iron cored structure transformer or reactor, window is high and multistage lamination is roomy little.This tri-phase iron core is by iron core column and 6 cross sectional shape approximate half-circular of 3 cross sectional shape sub-circulars, and two ends are converted into the last lower yoke at obtuse angle to be formed, and the sectional area size of each yoke is half of column sectional area.The slice length of each yoke iron slice is made up of arc length and length of straigh line, arc length is calculated according to mould arc radius (r) and lamination thickness (h) at different levels, length of straigh line calculates the length of each section by phase spacing (A) and at different levels wide calculating before processing.The every grade pet chip length of iron core column only has straight line portion, calculates with conventional plane iron core column.Utilize the chopper and slicer of existing planar alignment silicon steel sheet closed assembly structure iron core then, disposable respectively 3 iron core column and 6 straight yokes of being sliced into, 6 straight yokes utilize mould folding obtuse angle again.
When the assembling yoke, the tri-phase iron core post is 3-D triangle and places, and then yoke is inserted on two adjacent columns, and all iron core column and yoke through the band tighten, form a firm integral body through mitre or after directly stitching closed assembly at last.
