Abstract

The utility model discloses a novel transformer with composite winding for a three-phase electric welding machine, which comprises an iron-core leg and three-phase windings, wherein, one or two windings are concentric windings and the other windings are lap windings; by adopting the composite structure of the concentric windings and the lap windings, the transformer for the three-phase electric welding machine has good and appropriate dynamic properties, and less inductance needs to be adjusted, thus effectively reducing production cost and bringing about good universal property.

Description

Transformer device for novel combined wire winding three phase arc welder

Technical field

The utility model relates to a kind of transformer, particularly a kind of transformer device for novel combined wire winding three phase arc welder.

Background technology

Present three phase arc welder has two kinds of winding constructions with transformer, is respectively concentric type winding or folded formula winding.Wherein, with reference to the structural representation that Figure 1 shows that the three phase arc welder transformer of available technology adopting concentric type winding, the concentric type winding is that the high-low pressure winding is arranged with core on same stem stem, the low pressure winding is in the lining, the high pressure winding outside, perhaps the low pressure winding outside, the high pressure winding is in the lining.With reference to the structural representation of the three phase arc welder transformer that Figure 2 shows that the folded formula winding of available technology adopting, folded formula winding is the coil that the high-low pressure winding is divided into several portions likeness in form pie, is sleeved on the stem stem along the stem stem height.Existing three phase arc welder normally adopts as shown in the figure three consistent concentric type winding or three consistent folded formula windings with the three-phase of transformer, the shortcoming of its existence is, for the three phase arc welder transformer device structure that adopts consistent concentric type winding, it is dynamically very good, respond to very good, cause having very big splashing, need very big inductance, cause the cost height; And for adopting the consistent three phase arc welder transformer device structure of folding the formula winding, it exists electric current little, uncurrent shortcoming, and perhaps when electric current was big, its dynamic property was relatively poor, caused silk filling rate and production efficiency to descend.

Summary of the invention

At the problems referred to above, the purpose of this utility model is to provide a kind of low cost of manufacture, uses reliable, energy-conservation transformer device for novel combined wire winding three phase arc welder.

The technical scheme that the utility model adopted is:

Transformer device for novel combined wire winding three phase arc welder comprises core limb and three phase windings, and wherein one group or two groups of windings are the concentric type winding, and remaining winding is folded formula winding.

The beneficial effects of the utility model are: the composite construction that adopts above-mentioned concentric type winding and folded formula winding on same three phase arc welder transformer simultaneously, this transformer has good, suitable dynamic property, and need the inductance of adjustment less, can reduce manufacturing cost effectively, simultaneously highly versatile.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is the structural representation of the three phase arc welder transformer of available technology adopting concentric type winding;

Fig. 2 is the structural representation of the three phase arc welder transformer of the folded formula winding of available technology adopting;

Fig. 3 is execution mode one structural representation of three phase arc welder of the present utility model with transformer;

Embodiment

With reference to Fig. 3, Fig. 4, transformer device for novel combined wire winding three phase arc welder of the present utility model comprises core limb 1 and three

phase windings

2,3,4, and wherein one group or two groups of windings are the concentric type winding, remaining winding is folded formula winding, and promptly winding is a composite structure.

Wherein, as preferred implementation, with reference to shown in Figure 3, the winding the 2, the 4th on the core limb of the both sides of transformer, concentric type winding, the winding 3 on the middle core limb are folded formula windings.

In addition, as another kind of preferred implementation of the present utility model, as shown in Figure 4, and the winding the 2, the 4th on the core limb of the both sides of transformer, folded formula winding, the winding 3 on the middle core limb is concentric type windings.

Three phase arc welder of the present utility model is with the above-mentioned compound winding structure of transformer adopting, thereby makes this electric welder transformer have good dynamic characteristics, needs the inductance adjusted little, can reduce production costs effectively, and can energy efficient when using.

Certainly, the invention is except above-mentioned execution mode, and other equivalent technical solutions also should be within protection range of the present utility model.
