CN2585730Y - Balance reactor of three-phase arc welding power source - Google Patents

Abstract

The utility model relates to a balance reactor of a three-phase arc welding power source, which is composed of a coil, an iron core column and a yoke iron column. The utility model is characterized in that the coil is vertically wound on the iron core column; the wound iron core column by the coil and the yoke iron column are assembled and welded on a mounting bracket; the iron core column is formed by the weld of a plurality of laminations of the iron core column after the compacting of the laminations of the iron core column; the yoke iron column is formed by the weld of a plurality of laminations of the yoke iron column after the compacting of the laminations of the yoke iron 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 reactor is reduced, the manufacturing cost is reduced, and the service life of the reactor is prolonged.

Description

The paralleing reactor of three-phase Arc Welding Power

Affiliated technical field

The utility model relates to a kind of paralleing reactor, refers in particular to a kind of paralleing reactor of three-phase Arc Welding Power.

Background technology

In background technology, the paralleing reactor that is used for the three-phase Arc Welding Power is made up of coil, iron core column and yoke iron column, and iron core column adopts the blade inserting assembling, and coil adopts drum type brake coiling moulding, coil and iron core column are assembled, and the paralleing reactor 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 reactor service life; (3) 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; (4) owing to having air gap between coil and iron core column, so volume is bigger.

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 paralleing reactor of three-phase Arc Welding Power 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 paralleing reactor of three-phase Arc Welding Power, form by coil, iron core column and yoke iron column, it is characterized in that coil vertical is wound on the iron core column, the iron core column and the yoke iron column assembly unit of the good coil of coiling are welded on the mounting bracket.

Described iron core column is welded to form after being compressed by some iron core column laminations, and described yoke iron column is welded to form after being compressed by some yoke iron 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 reactor, has reduced manufacturing cost, has improved the service life of reactor.

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 paralleing reactor in the prior art.

Fig. 2 is the structural representation of present embodiment.

Fig. 3 is the schematic side view of Fig. 2.

Among the figure: 1, iron core column, 2, coil, 3, yoke iron column, 4, mounting bracket.

The specific embodiment

As shown in Figures 2 and 3, a kind of paralleing reactor of three-phase Arc Welding Power, be made up of coil 2, iron core column 1 and yoke iron column 3, it is characterized in that coil 2 vertical being wound on the iron core column 1, the iron core column 1 and yoke iron column 3 assembly units of the good coil 2 of coiling are welded on the mounting bracket 4.

In the present embodiment, described iron core column 1 is welded to form after being compressed by some iron core column laminations, and described yoke iron column 3 is welded to form after being compressed by some yoke iron column laminations.

When making, at first some iron core column laminations and some yoke iron column laminations are compressed the back welding with special fixture, again on the special purpose machine tool with coil 2 vertical being wound on the iron core column 1.Gap between iron core column lamination and yoke iron column lamination is reduced to bottom line like this, has also avoided simultaneously having reached the purpose that reduces vibration noise because of operational shock face causes the loosening phenomenon of hold-down bolt (in the prior art).

Because the utility model is rational in infrastructure, makes that the traditional paralleing reactor of volume ratio is little, has reduced manufacturing cost and function admirable, and is easy to assembly, adapt to requirement of mass production.
