Abstract
The utility model discloses a high frequency transformer, which comprises a primary coil, a magnetic core and a secondary coil, wherein the secondary coil is uniformly distributed in an annular array on the magnetic core, the primary coil is uniformly wound in an annular array on the magnetic core, and the magnetic core is fixed on the secondary coil. The high frequency transformer has high radiating speed, can meet the requirements of a spot welder on high current and high power of the high frequency transformer, and simultaneously has small volume, power economization, acid resistance, alkali resistance and high temperature resistance.
Description
Technical field
The utility model belongs to the transformer technology field, especially relates to a kind of high frequency transformer that is used for high-power output.
Background technology
High frequency switch power has been widely used in the resistance welding technology field, and its weak point is: high frequency transformer heat radiation difficulty, temperature rise is very high, therefore is difficult to improve power, can not satisfy spot welding machine to the big electric current of high frequency transformer, high-power requirement.The magnetic core of general high frequency transformer adopts ferrite, and the one, volume is big, and while power consumption is big, acidproof, alkaline-resisting and resistance to elevated temperatures is poor.
The utility model content
Deficiency at above-mentioned prior art existence, the purpose of this utility model provides a kind of high frequency transformer, its radiating rate is fast, can satisfy spot welding machine to the big electric current of high frequency transformer, high-power requirement, simultaneously little, the power saving, acidproof, alkaline-resisting, high temperature resistant of its volume.
To achieve these goals, the technical scheme that the utility model adopted is: a kind of high frequency transformer, comprise primary coil, magnetic core and secondary coil, and described secondary coil annular array is distributed on the magnetic core, the primary coil annular array is uniform to be wound on the magnetic core, and magnetic core is fixed on the secondary coil.
Described magnetic core is fixed on the secondary coil by the insulating tape banding.
Minimum distribution two circle primary coils between described per two secondary coils.
Described secondary coil is made of the outside insulating cement layer that coats of hook-shaped metallic conduction silk, magnetic core places in the hook, metallic conduction silk one end is weldingly fixed on the positive pole, the other end that form secondary coil on the copper coin and is weldingly fixed on down the negative pole that forms secondary coil on the copper coin, clamping has insulating cylinder between last copper coin and the following copper coin, and insulating cylinder is enclosed within on the secondary coil.
The described copper coin upper surface of going up is fixed with first insulating barrier, is fixed with second insulating barrier on the doffing plate.
Described copper coin down is made of first time copper coin and second time copper coin.
After adopting said structure, the utility model is compared the advantage that is had with prior art: when 1, using, dry facing to last copper coin and doffing plate with electric fan, because the positive and negative electrode of secondary coil adopts copper coin, secondary coil can pass through the copper coin quick heat radiating, can satisfy spot welding machine to the big electric current of high frequency transformer, high-power requirement.2, magnetic core adopts nanocrystalline magnetic conductor to manufacture to form, make that small product size is little, power saving, acidproof, alkaline-resisting, high temperature resistant.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation after cutting open along single secondary coil;
Fig. 4 is Fig. 1 upward view.
Embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection range of the present utility model.
Embodiment, see that Fig. 1 is to shown in Figure 4: a kind of high frequency transformer, comprise primary coil 2, magnetic core 3 and secondary coil 1, secondary coil 1 annular array is distributed on the magnetic core 3, primary coil 2 annular arrays are uniform to be wound on the magnetic core 3, and magnetic core 3 is fixed on the secondary coil 1.
Minimum distribution two circle primary coils 2 between per two secondary coils 1.
Following copper coin 5 is made of first time copper coin 51 and second time copper coin 52.
Because primary coil 2 and secondary coil 1 are evenly distributed on magnetic core 3, when electric fan blows to, easier heat radiation.Particularly the positive and negative electrode of secondary coil 1 adopts and goes up copper coin 4 and following copper coin 5, makes and can satisfy spot welding machine to the big electric current of high frequency transformer, high-power requirement by the utility model rapid heat dissipation.Simultaneously, adopt nanocrystalline magnetic conductor to manufacture magnetic core and form, make that small product size is little, power saving, acidproof, alkaline-resisting, high temperature resistant.
