Description

A kind of amorphous alloy high frequency transformer

Technical field:

The utility model relates to the transformer technology field, more specifically to a kind of amorphous alloy wet type transformer.

Background technology:

The amorphous alloy transformer is compared with the crystal alloy transformer, manages characteristic, chemical property and mechanical properties the spy significant variation has all taken place.Be example with the iron-based non-crystalline transformer, it has high full close magnetic flux density and low-loss characteristics.Therefore transformer industry adopts the amorphous alloy transformer to replace traditional transformer in a large number at present.There is the relatively poor problem of heat dispersion in existing amorphous alloy high frequency transformer.

The utility model content:

The purpose of this utility model is exactly the deficiency at prior art, and a kind of amorphous alloy high frequency transformer is provided, its perfect heat-dissipating, and magnetic core is rapid heat dissipation under the situation of fan blowing, can continuous operation.

Technology solution of the present utility model is as follows:

A kind of amorphous alloy high frequency transformer, comprise magnetic core, primary coil and secondary coil, the primary coil and the secondary coil that have insulating barrier all are wound on the magnetic core, the positive pole of secondary coil is fixed on first copper coin, the negative pole of secondary coil is fixed on second copper coin, clamping has insulating cylinder between first copper coin and second copper coin, and magnetic core is fastened on secondary coil by band, and secondary coil is hook-shaped metallic conductor by several and forms;

Magnetic core is made up of box body, lid and the amorphous alloy band that is wound on together, the amorphous alloy band that is wound on together places box body, lid is screwed onto on the box body, is filled with silica gel between amorphous alloy band and the inboard wall of cartridge, all forms air-vent on box body and the lid.

Described each positive pole that is hook-shaped secondary coil is weldingly fixed on first copper coin, negative pole is weldingly fixed on second copper coin, is adhesively fixed with first insulating barrier on first copper coin, is adhesively fixed with second insulating barrier on second copper coin.

The beneficial effects of the utility model are:

Its perfect heat-dissipating, magnetic core is rapid heat dissipation under the situation of fan blowing, can continuous operation.

Among the figure: 1, magnetic core; 2, primary coil; 3, secondary coil; 4, first copper coin; 5, second copper coin; 6, insulating cylinder; 7, first insulating barrier; 8, second insulating barrier; 9, band; 10, box body; 11, lid; 12, be wound on together amorphous alloy band; 13, silica gel; 14, air-vent.

Embodiment:

Embodiment: see shown in Fig. 1 to 4, a kind of amorphous alloy high frequency transformer, comprise magnetic core 1, primary coil 2 and secondary coil 3, the primary coil 2 and the secondary coil 3 that have insulating barrier all are wound on the magnetic core 1, the positive pole of secondary coil 3 is fixed on first copper coin 4, the negative pole of secondary coil 3 is fixed on second copper coin 5, clamping has insulating cylinder 6 between first copper coin 4 and second copper coin 5, magnetic core 1 is fastened on secondary coil 3 by band 9, and secondary coil 3 is hook-shaped metallic conductor by several and forms;

Magnetic core 1 is made up of box body 10, lid 11 and the amorphous alloy band 12 that is wound on together, the amorphous alloy band 12 that is wound on together places box body 10, lid 11 is screwed onto on the box body 10, be filled with silica gel 13 between amorphous alloy band 12 and box body 10 inwalls, all form air-vent 14 on box body 10 and the lid 11.

Described each positive pole that is hook-shaped secondary coil 3 is weldingly fixed on first copper coin 4, negative pole is weldingly fixed on second copper coin 5, is adhesively fixed with on first copper coin 4 on first insulating barrier, 7, the second copper coins 5 and is adhesively fixed with second insulating barrier 8.

Operation principle: it is when work, dry to dispel the heat facing to magnetic core by electric fan, owing to form air-vent 14 on its magnetic core 1, so magnetic core can be dispelled the heat well, secondary coil 3 also can be by

first copper coin

4 and 5 heat radiations of second copper coin simultaneously, and the heat radiation of primary coil 2 mainly is directly to dispel the heat by the wind that electric fan blows.
