Abstract
A kind of novel transformer rewinding material, comprise iron-core workpiece, iron-core workpiece by two identical single-phase rewinding material and an outside single-phase rewinding material assembled, the middle of the upper and lower iron yoke of single-phase rewinding material of its peripheral has bending to the inside, central folding bent angle is 90 degree, and bending angle, two ends is 145 degree; In upper and lower yoke and the stem junction of 3 single-phase rewinding material, same formation two bending angles, every bending angle is 150 degree, and every layer of silicon steel sheet is through bending twice; Design two fractures at every layer of silicon steel sheet, fracture site is arranged on stem upper end.The utility model is ensureing, on the basis that conventional rewinding material performance is constant, all to be solved by original all problems.
Description
Technical field
The utility model relates to a kind of transformer, particularly relates to a kind of novel transformer rewinding material.
Background technology
In the last few years along with country's wideling popularize energy-conserving product, rewinding material application is on the transformer more and more extensive, this iron core is formed by relevant device continuous reeling by one or more silicon steel sheet long band, the transformer be assembled by rewinding material aspect of performance comparatively traditional product have greater advantage to promote, be mainly reflected in that no-load performance is superior, take up room the advantage such as little.But rewinding material is jointless structure, also there is many problems, as: manufacturing equipment production capacity is limited, needs special spooling equipment during ironcore choke coiling, and will carry out coiling with iron core, and winding process difficulty, complexity, production efficiency are low.Maintenance aspect is very difficult especially, and transformer, once coil breaks down, just cannot take off coil from iron core and change, can cause scrapping of whole transformer; And also there is insurmountable problem in a structure in rewinding material, because the three-phase transformer rewinding material of routine, an air section compared with large regions (transformer term claims this sheet air section for " air-gap ") is there is in the top and the bottom of center pillar unshakable in one's determination, the magnetic line of force is made to pass through this region, sizable magnetic resistance (magnetic line of force should be walked in silicon steel sheet) can be produced, thus make this region can produce high order harmonic component when transformer normally runs to have an impact to grid supply quality, and heat and certain no-load loss can be produced in this region.These problems all directly have impact on the application of rewinding material above.
Utility model content
The purpose of this utility model is exactly for overcoming the defect and deficiency that above-mentioned prior art exists, and providing a kind of novel transformer rewinding material.This rewinding material arranges two open positions at every layer of silicon steel sheet, open position is arranged on stem upper end, simultaneously in the middle of most housing iron core, carries out bending to the inside, so just, air section can be filled by silicon steel sheet completely, problem described before conventional rewinding material just can be solved completely.
The technical scheme adopted is:
A kind of novel transformer rewinding material, comprise iron-core workpiece, iron-core workpiece by two identical single-phase rewinding material and an outside single-phase rewinding material assembled, the middle of the upper and lower iron yoke of single-phase rewinding material of its peripheral has bending to the inside, central folding bent angle is 90 degree, and bending angle, two ends is 145 degree; In upper and lower yoke and the stem junction of 3 single-phase rewinding material, same formation two bending angles, every bending angle is 150 degree, and every layer of silicon steel sheet is through bending twice; Design two fractures at every layer of silicon steel sheet, fracture site is arranged on stem upper end.
Beneficial effect is, the utility model is ensureing, on the basis that conventional rewinding material performance is constant, all to be solved by original all problems.

Specific embodiments
See Fig. 1, conventional rewinding material in the middle of upper and lower iron yoke at air section 5.
See Fig. 2, the utility model is assembled by the single-phase rewinding material 3 that two identical single-phase rewinding material 1,2 and are outside, wherein the intermediolateral column 8 of two identical single-phase rewinding material 1,2 and 135 degree, the bending angle of upper and lower iron yoke 4; The middle of the outside upper and lower iron yoke 4 of single-phase rewinding material 3, carry out bending to the inside, central folding bent angle is 90 degree, and bending angle, two ends is 135 degree, air section 5 all can be filled like this; In upper and lower yoke and stem 6 junction of 3 single-phase rewinding material, same formation two bending angles, every bending angle is 150 degree, and the bending part of every layer of silicon steel sheet need through bending twice; Design two fractures at every layer of silicon steel sheet, silicon steel sheet is sheared disconnection can form fracture, and fracture site 7 is arranged on stem upper end.
See two that demonstrate the upper and lower iron yoke of outside single-phase rewinding material 3 in Fig. 3, figure middle 90 degree, bending angles, and 135 degree, bending angle, two ends; Upper and lower yoke and bending angle, two, stem junction are the position of 150 degree, and the sheet shape of every sheet silicon steel sheet.
See demonstrating the position that the upper and lower yoke of single-phase rewinding material 1 and bending angle, two, stem junction are 150 degree in Fig. 4, figure, and 135 degree, bending angle, other side, and the sheet shape of every sheet silicon steel sheet.
See demonstrating the position that the upper and lower yoke of single-phase rewinding material 2 and bending angle, two, stem junction are 150 degree in Fig. 5, figure, and 135 degree, bending angle, other side, and the sheet shape of every sheet silicon steel sheet.
