Technical field
The utility model belongs to the transformer technology field, is specifically related to a kind of amorphous alloy transformer coil.
Background technology
Existing amorphous alloy transformer all comprises square coil and the rectangular core that locks together, wherein square coil is provided with high-tension coil and low-voltage coil, described high-tension coil is sleeved on the low-voltage coil, be provided with main empty path between the two, main empty path increases the creepage distance between the coil, realizes the insulation between high-tension coil and the low-voltage coil.But high-tension coil and low-voltage coil all are to be formed by the enamelled wire coiling.And stressed separately situation is different during the high and low pressure coil short, its width of cloth is inside pressure to power during the low-voltage coil short circuit, its width of cloth is to be pulled outwardly to power during the high-tension coil short circuit, the axial force of the two all is to draw toward two ends, the width of cloth is excessive to power and axial force, will cause winding deformation, draw bad enamelled wire, cause coil to scrap.
The shortcoming of prior art: when the high and low pressure coil short, the width of cloth that can't overcome the high and low pressure coil is to power and axial force, and the width of cloth is excessive to power and axial force, will cause winding deformation, draws bad enamelled wire, causes coil to scrap.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of anti-short circuit distortion transformer, even the high and low pressure coil short, the width of cloth that also can overcome the high and low pressure coil is to power and axial force, and the protection coil can not be out of shape, and avoids so causes coil to scrap.
The technical solution of the utility model is as follows: a kind of anti-short circuit distortion transformer, comprise the square coil and the rectangular core 1 that lock together, wherein square coil is provided with high-tension coil 2 and low-voltage coil 3, described high-tension coil 2 is sleeved on the low-voltage coil 3, be provided with main empty path 4 between the two, its key is: the inwall at described low-voltage coil 3 is fixed with supporting bracket 5, is fixed with pressing plate 6 at the outer wall of described high-tension coil 2.
Supporting bracket 5 is fixed on the inwall of low-voltage coil 3, is close on the low-voltage coil 3, and the width of cloth inside when being used to overcome low-voltage coil 3 short circuits is to pressure.Pressing plate 6 is fixed on the outer wall of high-tension coil 2, is close on the high-tension coil 2, and the width of cloth outside when being used to overcome high-tension coil 2 short circuits is to pulling force.
Supporting bracket 5 and pressing plate 6 protection coils can not be out of shape, and avoid so cause coil to scrap.
Described supporting bracket 5 and pressing plate 6 are bundled on the described square coil through shrink belt 7.
Multiple tracks shrink belt 7 is bundled in supporting bracket 5 and pressing plate 6 on the coil, strengthens the non-deformability of supporting bracket 5 and pressing plate 6.
The two ends of described supporting bracket 5 all are provided with bending, and this supporting bracket bending part 5a is bundled in the two ends of described low-voltage coil 3 through described shrink belt 7.
When supporting bracket bending part 5a is used to overcome low-voltage coil 3 short circuits to the axial tension at two ends.
The two ends of described pressing plate 6 all are provided with bending, and this pressing plate bending part 6a is bundled in the two ends of described high-tension coil 2 through described shrink belt 7.
When pressing plate bending part 6a is used to overcome high-tension coil 2 short circuits to the axial tension at two ends.
Remarkable result of the present utility model is: strengthen the non-deformability of coil, even the high and low pressure coil short, the width of cloth that also can overcome the high and low pressure coil guarantees that to power and axial force coil can not be out of shape, and the protective paint envelope curve can not draw bad, avoids coil to scrap.
