Each single-phase iron core is divided into an upper part and a lower part, the joint of an iron yoke and a core column of each upper part is arranged to be a bent structure, and the range of a bending angle is from 120 degrees to 150 degrees; the joint of an iron yoke and a core column of each lower part is arranged to be of an arc structure, turning radius R of an arc is equal to width of each core column, and a fracture of each iron core is arranged at the bent position of each iron core and each column. The three-dimensional reel iron core of the transformer has the advantages of convenience in manufacturing, improvement on transformer production, easiness in maintenance and the like.
Description
Technical field
The utility model relates to transformer manufacture technology, particularly relates to a kind of transformer three-dimensional winding iron core.Relevant background technology
background technology
Transformer is mainly made up of iron core and coil two large divisions.Along with country is to the wideling popularize of energy-conserving product, the product that one is called " coiled iron core " had been widely used in transformer in the last few years.Coiled iron core is called again " volume iron core ", this iron core is to be formed by relevant device continuous reeling by one or more silicon steel length of a film band, the transformer being formed by volume iron core assembly has greater advantage to promote at aspect of performance compared with traditional product, is mainly reflected in the advantages such as no-load loss is low, noise is little, volume is little.Volume iron core is totally divided into two kinds, and one is plane reeling iron core; Another kind is stereo-triangular wound iron core.Stereo-triangular wound iron core is because the special construction of its three-phase magnetic circuit full symmetric makes various aspects of performance more superior.But because volume iron core is jointless structure, also there is many problems, as: manufacturing equipment production capacity is limited, and iron-core coil when coiling needs special spooling equipment, and will wind the line with iron core, and winding process difficulty, complexity, production efficiency are low.Especially cannot solve the problems such as the paint-dipping process of formula transformer coiling.Maintenance aspect is very difficult especially, once transformer coil breaks down, just cannot take off coil from iron core and change, and must cause scrapping of whole transformer.
Utility model content
The utility model provides a kind of transformer three-dimensional winding iron core, this volume iron core is to be combined by three identical single-phase iron cores of profile, the corner bending part of each single-phase iron core successively designs a fracture site, and be set to folding type structure at the upper yoke of single-phase iron core the first half and the junction of stem, and the lower yoke of single-phase iron core the latter half and the coupling part of stem are set to circular arc type structure.The utility model has thoroughly solved whole issue described before conventional stereo-triangular wound iron core.
The technical scheme adopting is:
A kind of transformer three-dimensional winding iron core, comprise three single-phase iron cores that profile is identical, it is characterized in that described each single-phase iron core is divided into upper and lower two parts, wherein the junction of the first half iron yoke and stem is set to folding type structure, and bending angle scope is between 120 °～150 °; The coupling part of the latter half iron yoke and stem is set to circular arc type structure, and the radius of turn R of circular arc equates with the width of stem, and the fracture site of iron core is arranged on the bending part of iron yoke and stem.
The beneficial effects of the utility model are: this iron core possesses the performance of conventional stereo-triangular wound iron core, and in transformer production manufacture process, do not need special volume iron core winding equipment, coil coiling separately.When mounting coil enters iron core, iron core can be separated and opened by incision position, then mounting coil is entered in stem, finally by compound the iron core plug-in mounting under separating.The advantage that the junction of each single-phase iron core the first half iron yoke and stem is set to folding type structure is to facilitate plug-in mounting compound, and in plug-in mounting recombination process, every silicon steel sheet all can be according to identical angle one by one near plug-in mounting, and precision high efficiency is fast.The advantage that the coupling part of each single-phase iron core the latter half iron yoke and stem is set to circular arc type structure is to reduce the production difficulty of iron core, between each layer of silicon steel sheet of iron core, by the radian moulding of certain radius, be set to folding type structure than the junction of the first half iron yoke and stem comparatively easy.Therefore the utility model possesses and is convenient to manufacture, improves transformer production efficiency and the advantage such as for ease of maintenaince.

Embodiment
Referring to Fig. 1, Fig. 2, the utility model is to be combined by three identical single-phase iron cores 10 of profile, and whole iron core comprises three stems 8, three upper yokes 3 and three lower yokes 4.Referring to Fig. 2, Fig. 3, each stem 8 is combined by two stems 6 of two single-phase iron cores 10 again.
Referring to Fig. 3, each phase iron core is made up of two stems 6, upper yoke 3 and lower yoke 4, can be divided into upper and lower two parts according to center line 1; Wherein the first half iron yoke 3 is set to folding type structure with the junction 7 of stem 6 according to certain angle, and referring to Fig. 4, the angular range of bending angle A is 120 degree.Referring to Fig. 3, the latter half iron yoke 4 is set to circular arc type structure with the coupling part 5 of stem 6.Referring to Fig. 4, the radius of turn R of circular arc equates with the width L of stem 6.
Referring to Fig. 5, fracture site 2 is the bending part with stem 6 at the first half iron yoke 3.
