Be illustrated in figure 1 as the structure chart of traditional transformer technology, as can be seen from the figure, the former limit of transformer and secondary are all used many enamelled wire sandwich wounds.The shortcoming of this transformer comprises:
1. task difficulty is big, and complex process is loaded down with trivial details, and big to operating personnel's degree of dependence, automaticity is lower, and production efficiency is extremely low.
2. the technology with the reflexed adhesive tape not only makes the transformer manufacture difficulty strengthen, and more makes line bag radiating effect variation.
3. proximity effect and skin effect are bigger, and the winding A.C.power loss is higher, and the transformer temperature rise is higher.
The utility model content
Technological deficiencies such as the purpose of the utility model provides a kind of electric welding machine and uses transformer, and the A.C.power loss that solves the prior art existence is big, radiating effect is poor, temperature rise is big, manufacture craft is loaded down with trivial details.
To achieve these goals, the transformer that the utility model provides comprises skeleton and is wound in the winding of skeleton, and winding comprises former limit winding and secondary winding, and former limit winding is a twisted wire, promptly in line now; The secondary winding is the Copper Foil that coats of insulated body partly.The secondary winding comprises the first secondary winding and the second secondary winding, and former limit winding technique is between the first secondary winding and the second secondary winding.Near the position of skeleton, the second secondary winding technique is in skin in for the first secondary winding technique.Isolate with the coil adhesive tape between the winding of former and deputy limit.Winding two ends, former limit are provided with barricade, to guarantee the safe distance between the former secondary.Insulator is an insulating tape, and insulating tape all covers the one side of Copper Foil, and part covers the another side of Copper Foil.Skeleton is a tubular, and the upper and lower edge of stack shell extends flange respectively, and flange connects other associated components such as drawing pin.The secondary winding is provided with at least one lead-out wire, and said lead-out wire is drawn from Copper Foil, said lead-out wire respectively with draw pin and be electrically connected.
The utility model is compared with prior art, and the transformer that the utility model provides can effectively reduce proximity effect and skin effect, thereby reaches the purpose that the AC resistance that reduces winding reduces the A.C.power loss of winding; And its structure is beneficial to the transformer heat radiation and reduces the temperature rise of load transformer; Also solved existing transformer complicacy and loaded down with trivial details manufacture craft problem, the simplification manufacture craft reduces the height dependence of operation to people's qualification, and effectively lifting manufacturing scale and automaticity promote production efficiency.

Embodiment
Below in conjunction with accompanying drawing, introduce the embodiment of the utility model.
Like Fig. 2 and shown in Figure 3, the transformer that the utility model provided comprises skeleton 10 and is wound in the winding 20 on the skeleton 10.Skeleton 10 is a tubular, and the upper and lower edge of stack shell extends the flange vertical with stack shell 11 respectively, and flange 11 connections are drawn pin 30 and waited other associated components.Winding 20 is wound in the stack shell of skeleton 10.Winding 20 comprises the first secondary winding 21, former limit winding 22 and the second secondary winding 23.The first secondary winding 21 and the second secondary winding 23 are twisted wire for gum Copper Foil, former limit winding, promptly in line now.
Please consult Fig. 4 in the lump, the first secondary winding 21 is wound in the position near skeleton 10 stack shells.Former limit winding 20 is wound between the first secondary winding 21 and the second secondary winding 23.The second secondary winding 23 is wound in skin.Isolate with coil adhesive tape 25 between the winding of former and deputy limit.Winding 20 two ends, former limit are provided with barricade 24, to guarantee necessary security distance between the former secondary.
The first secondary winding 21 and the second secondary winding 23 are the Copper Foil 231 that coats of insulated body 233 partly.Be the gum Copper Foil in this execution mode, it comprises Copper Foil 231 and partly coats insulator 233 on it that in this execution mode, insulator 233 is an insulating tape.As shown in Figure 4, insulating tape 233 all covers the one side of Copper Foil 231, and partly covers the another side of Copper Foil 231, only stays mid portion not to be coated.Insulator 233 covers the both side edges of Copper Foil 231, and covers the both sides of Copper Foil 231 one sides, exposes mid portion.
The first secondary winding 21 and the second secondary winding 23 are provided with complex root lead-out wire 235 respectively, and said lead-out wire 235 is drawn from Copper Foil 231 respectively, said lead-out wire 235 respectively with draw pin 30 and be electrically connected.
Former limit winding 20 is a twisted wire, promptly in line now, stranded or braiding forms by the conductor of many independent insulation, and is normally stranded by enamel covered wire.
The transformer of the utility model is to the not restriction of the number of plies of former limit, two secondary coilings, the flexible coiling of parameter request that can satisfy as required.
This transformer is the structure that adopts former limit, two staggered coilings of secondary.The secondary winding is respectively whole piece gum Copper Foil, the integral body that each secondary has been made in advance, and the technique for coiling of simplification Transformer Winding is more suitable in scale and automated production.And, because assembly still less, makes the whole high-frequency loss of winding lower, and can effectively reduce proximity effect and skin effect, thereby reach the purpose that the AC resistance that reduces winding reduces the A.C.power loss of winding; And be beneficial to the temperature rise of transformer heat radiation and reduction load transformer.
The above only is a kind of embodiment of the utility model, is not that the technical scope of the utility model is done any restriction, and for example, the number of plies of former limit, secondary coiling is restriction not, and the shape of skeleton is not limited to cylindric described in the figure.Therefore; The technical staff of the industry under the inspiration of technique scheme, can make some distortion and revise; Every technical spirit according to the utility model all still belongs to the protection range of the utility model claim to above any modification, equivalent variations and modification that embodiment did.
