Abstract
The utility model relates to a three-phase arc-welding power source transformer which is composed of a coil, iron core columns and a yoke iron column, wherein, the coil comprises a first coil and a secondary coil. The utility model is characterized in that the first coil is flat wound on the iron core column; the secondary coil is vertically wound on the outer side of the first coil; the yoke iron column is positioned between the wound iron core column by three-phase coils, after assembly and weld, the yoke iron column is fixed on a mounting bracket; each of the iron core columns is formed by the weld of a plurality of laminated sheets of the iron core column, after the compacting of the laminated sheets of the iron core column. Because of the reasonable structural design of the utility model, the clearance gap between each of the coils and one of the iron core columns is reduced; the radiating areas of the coils are increased; therefore, the volume of the transformer is reduced, the manufacturing cost is reduced, and the service life of the transformer is prolonged.
Description
Affiliated technical field
The utility model relates to a kind of transformer, refers in particular to a kind of three-phase Arc Welding Power transformer.
Background technology
In background technology, the transformer that is used for the three-phase Arc Welding Power is made up of coil, iron core column and yoke iron column, coil comprises primary coil and secondary coil, iron core column adopts the blade inserting assembling, coil adopts drum type brake coiling moulding, coil and iron core column are assembled, and the three-phase Arc Welding Power transformer of this structure as shown in Figure 1.There is following shortcoming in it: (1) coil adopts drum type brake coiling moulding, weak heat-dissipating, cost height; (2) iron core column adopts bolt compacted iron stem stem lamination to form, and easily produces vibration noise in running, influences transformer useful life; (3) owing to having air gap between coil and iron core column, so volume is bigger; (4) in when assembling, iron core column lamination and yoke iron column lamination intersect closed assembly, and work efficiency is low, the incompatibility production in enormous quantities.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective that exists in the prior art, and a kind of three-phase Arc Welding Power transformer is provided, and it is rational in infrastructure, manufacturing and easy to assembly, and volume is less.
For achieving the above object, the solution that the utility model is taked is: a kind of three-phase Arc Welding Power transformer, form by coil, iron core column and yoke iron column, coil comprises primary coil and secondary coil, it is characterized in that primary coil is flat on iron core column, secondary coil is vertical to be wound on outside the primary coil, places between the iron core column of the good coil of three-phase coiling to be fixed on the mounting bracket after the yoke iron column assembly unit is welded.
Described iron core column is welded to form after being compressed by some iron core column laminations.
The utility model compared with prior art because reasonable in design has reduced the gap between coil and iron core column, and increased the area of dissipation of coil, thereby reduced the volume of transformer, has reduced manufacturing cost, has improved the useful life of transformer.
Description of drawings
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Fig. 1 is the structural representation of three-phase Arc Welding Power transformer in the prior art.
Fig. 2 is the structural representation of present embodiment.
Fig. 3 is the structural representation of the iron core column of the good coil of a phase coiling among Fig. 2.
Among the figure: 1, iron core column, 2, primary coil, 3, secondary coil, 4, yoke iron column, 5, mounting bracket.
Embodiment
As shown in Figures 2 and 3, a kind of three-phase Arc Welding Power transformer, form by coil, iron core column 1 and yoke iron column 4, coil comprises primary coil 2 and secondary coil 3, it is characterized in that primary coil 2 is flat on iron core column 1, secondary coil 3 vertical being wound on outside the primary coil 2 are fixed on the mounting bracket 5 after the placement yoke iron column 4 assembly units welding between the iron core column 1 of the good coil of three-phase coiling.
In the present embodiment, described iron core column 1 is welded to form after being compressed by some iron core column laminations.
When making, at first some iron core column laminations are compressed the back welding with special fixture, again on the special purpose machine tool with primary coil 2 flat on iron core column 1, secondary coil 3 vertical being wound on outside the primary coil 2.Reduce the gap of 1 of coil and iron core column like this, and increased the area of dissipation of coil, thereby reduced the volume of transformer, reduced manufacturing cost.Will be between the iron core column 1 of the good coil of three-phase coiling place yoke iron column 4, utilize yoke iron column 4 to connect and welding after, be fixed on again on the mounting bracket 5, reduce air gap between the iron core column lamination to bottom line, reached the purpose that reduces vibration noise.
Because the utility model is rational in infrastructure, all the three-phase Arc Welding Power transformer than traditional is little to make volume, weight, has reduced manufacturing cost and function admirable, and is easy to assembly, adapts to requirement of mass production.
