Abstract

Disclosed is a triangle iron core amorphous alloy transformer which comprises an amorphous alloy iron core, a low-pressure winding, a high-tension winding and electric insulation oil, which is characterized in that the amorphous alloy iron core is a triangle iron core which is coiled by the amorphous alloy belt, compare to the conventional amorphous alloy transformer, the triangle iron core amorphous alloy transformer has the advantages that the transformer is provided with a triangle arrangement by the three same stems which in the iron core and in magnetic shunt symmetrical distribution, thereby, the idle current is in symmetrical distribution, a lateral section is employed by the fuel tank which the shape is the same with the triangle iron core, the fuel tank volume and the electric insulation oil cost are maximum limit reduced, the amorphous alloy transformer cost can be reduced, the transformer can be used in city power distribution, high-rise building, residential area, park, express highway, oil field, industrial and mining establishments and the job location.

Description

Triangle Core Non-crystalline Transformer

Technical field

The utility model relates to a kind of transformer, relates in particular to a kind of amorphous alloy transformer.

Background technology

The characteristics non-crystaline amorphous metal of amorphous alloy material is the exsertile material of a kind of novel magnetic conductivity, adopt rapid quench to solidify production technology, its physical state shows as metallic atom and is unordered noncrystal arrangement, and it is different fully with the crystal structure of silicon steel, is more conducive to be magnetized and degaussing.Typical amorphous alloy contains 80% iron, and other composition is boron and silicon.

The iron core of amorphous alloy transformer is three-phase five-limb two row rectangular arranged in the prior art, flows through the zero sequence magnetic flux in two other posts, and magnetic flux does not produce the structure loss of heating without casing, makes transformer can satisfy low noise, low-loss; Because amorphous alloy transformer has little and the characteristics that the economical operation load factor is relatively low of no-load loss.Since iron core be three-phase and five-pole in one plane, therefore cause A phase, C phase magnetic circuit longer, B phase magnetic circuit is shorter, causes the transformer three-phase current unbalance.

The utility model content

The purpose of this utility model is the technical problem that solves amorphous alloy transformer three-phase current unbalance of the prior art.

The technical solution of the utility model is:

A kind of Triangle Core Non-crystalline Transformer comprises amorphous alloy iron core, low pressure winding, high pressure winding, transformer wet goods part, it is characterized in that described amorphous alloy iron core is by non-crystaline amorphous metal tape wrapping angle iron core.

Triangle iron core can be made of three single-phase iron cores, the cross section sub-circular or the ellipse of each single-phase iron core, the center of circle of three single-phase cross sections unshakable in one's determination is triangular arranged, each single-phase iron core is spliced to form by two single-phase iron core column respectively, the equal semicircular in shape of the cross section of each single-phase iron core column, each single-phase core limb constitutes by continuous non-crystaline amorphous metal tape wrapping.

Described fuel tank cross section can adopt triangle.

The beneficial effects of the utility model are: Triangle Core Non-crystalline Transformer has following advantage with respect to existing amorphous alloy transformer: amorphous alloy transformer is arranged by three identical stem stems and is triangularly arranged, the magnetic circuit of three cylinders of iron core is symmetrically distributed, and makes that no-load current also is to be symmetrically distributed; The fuel tank cross section adopts triangle, and is identical shaped with the triangle iron core, can at utmost reduce fuel tank volume and transformer oil use amount, reduced the cost of amorphous alloy transformer.

Among the figure: 1, amorphous alloy iron core 2, low pressure winding 3, high pressure winding 4, fuel tank 5, transformer oil 6, case lid 7, conservator 8 fin

Embodiment

As shown in Figure 3, the amorphous alloy iron core of Triangle Core Non-crystalline Transformer is made of three single-phase iron cores, the cross section sub-circular or the ellipse of each single-phase iron core, the center of circle of the cross section of three single-phase iron cores is triangular arranged, each single-phase iron core is spliced to form by two single-phase iron core column respectively, the equal semicircular in shape of the cross section of each single-phase iron core column, each single-phase iron core column constitutes by continuous non-crystaline amorphous metal tape wrapping.

As shown in Figure 1, the triangle Wound iron-core transformer mainly is made up of fuel tank 4, low pressure winding 2, high pressure winding 3 and amorphous alloy iron core 1 etc., the inside of fuel tank 4 be transformer oil 5, low pressure winding 2, high pressure winding 3 and amorphous alloy iron core 1 are immersed in the transformer oil 5, case lid 6 is sealed in transformer oil 5 in the fuel tank 4, and low pressure winding 2 and high pressure winding 3 are the copper winding of rectangle, when coil is short-circuited accidentally, can adapt to bigger mechanical stress and destroy, coil does not produce distortion.The cross section of fuel tank 4 adopts leg-of-mutton as shown in Figure 2, fuel tank is furnished with radiator 8, transformer oil 5 is housed in the conservator 7 to communicate with the transformer oil 5 of fuel tank 4, the main effect of conservator 7 is to change along with oil overflows and expand or when dwindling when the volume of

transformer oil

5,7 oil storages of conservator and repairing act on, and can guarantee to be full of oil in the fuel tank 4, simultaneously owing to adorned conservator 7, make the contact-making surface of transformer and air little, slowed down oily degradation speed.Oil level indicator also is equipped with in the side of conservator 7, can monitor the variation of oil level.
