Abstract
A three-phase transformer rolled iron core comprises an upper part and a lower part. The three-phase transformer rolled core is characterized in that joints between an iron yoke of the upper half part and core pillars are of bent structures, the angular range of each bending angle is between 120 degrees and 150 degrees, and connecting parts between an iron yoke of the lower half part and the core pillars are arranged as circular arc-shaped structures. Fractures of the iron core are arranged on the bends of the iron yoke and the core pillars. The three-phase transformer rolled iron core has the advantages that the three-phase transformer rolled iron core is convenient to manufacture and easy to repair, the efficiency of transformer production can be increased and the like.
Description
Technical field
The utility model relates to transformer core and manufactures field, particularly relates to a kind of three-phase transformer volume unshakable in one's determination.
Background technology
Transformer is mainly made up of unshakable in one's determination and coil two large divisions.Along with country is to the wideling popularize of energy-conserving product, the product that one is called " Winding iron core " had been widely used in transformer in the last few years.Winding iron core is called again " volume is unshakable in one's determination ", this iron core is to be formed by relevant device continuous reeling by one or more silicon steel length of a film band, there is greater advantage to promote at aspect of performance compared with traditional product by the volume transformer being assembled unshakable in one's determination, be mainly reflected in the advantages such as no-load loss is low, noise is little, volume is little.But because volume iron core be jointless structure, also there is many problems, as: manufacturing equipment production capacity is limited, the ironcore choke special spooling equipment of time needs that winds the line, and will winding 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 purpose of this utility model is exactly defect and the deficiency existing for overcoming above-mentioned prior art, and provide a kind of three-phase transformer volume unshakable in one's determination, this volume iron core successively designs a fracture site at corner bending part, and be set to folding type structure at the upper yoke of the first half unshakable in one's determination and the junction of stem, and the lower yoke of the latter half unshakable in one's determination and the coupling part of stem are set to circular arc type structure.The utility model has thoroughly solved whole issue described before conventional volume iron core.
The technical scheme adopting is:
A kind of three-phase transformer volume is unshakable in one's determination, comprise upper and lower two parts, the junction that it is characterized in that the first half iron yoke and stem is folding type structure, and the angular range at bending angle is that between 120～150 degree, the coupling part of the latter half iron yoke and stem is set to circular arc type structure.Fracture site unshakable in one's determination is arranged on the bending part of iron yoke and stem.
The beneficial effects of the utility model are: this iron core possesses conventional volume performance unshakable in one's determination, and in transformer production manufacture process, do not need special volume spooling equipment unshakable in one's determination, 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 plug-in mounting unshakable in one's determination under separating.The advantage that the junction of 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 the latter half iron yoke and stem is set to circular arc type structure is to reduce production difficulty unshakable in one's determination, between each layer of silicon steel sheet unshakable in one's determination, 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.

Fig. 2 end view of the present utility model.
The view of Fig. 3 the utility model the first half bending angle and the latter half arc radius.
Fig. 4 the utility model fracture site is at the view of the bending part of the first half iron yoke and stem.
Specific embodiments
Referring to Fig. 1, whole three-phase iron core is made up of three 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.Referring to Fig. 3, bending angle A is 130 °.Referring to Fig. 1, the latter half iron yoke 4 is set to circular arc type structure with the coupling part 5 of stem 6.Referring to Fig. 3, the radius of turn R of circular arc equates with the width L of stem 6.
Referring to Fig. 4, fracture site 2 is the bending part with stem 6 at the first half iron yoke 3.
