Abstract
The utility model relates to a coil structure in a transformer, which comprises a coil with N turns. The utility model is characterized in that the coil is elliptical. The utility model has the benefit of reducing the material consumption of an iron core while reducing the no-load loss of the transformer.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to coil in a kind of dry-type transformer.
Background technology
Transformer is a kind of static electrical equipment.Utilize electromagnetic induction principle between two or more coils, convert a kind of voltage and current of grade to voltage and current and electric energy transmitting with the another kind of grade of screen rate.
Coil is the basic element of character of transformer voltage of transformation, and coil is made up of the different numbers of turn, because every circle voltage of different coils is the same, therefore, need make coil that the different numbers of turn is arranged, and reaches different voltage.
Insulation at transformer coil in service also will sustain instantaneous atmospheric over-voltage, internal overvoltage (containing switching overvoltage) and long-term work voltage.Atmospheric over-voltage is even more serious to the influence of coil.
Transformer is when operation, and by electric current, the loss that has a resistance in coil-conductor can cause the efficient of generating heat and reducing transformer in the coil.Coil uses the high metal of conductivity to make for this reason, and conductor commonly used is a copper.
As seen from Figure 1: since coil 1 be circular, volume ratio is bigger, used copper material is many.The space that winding volume occupies greatly is also big, because coil is enclosed within on the core limb, the volume increase of coil also causes unshakable in one's determination the increase.
And the no-load performance of transformer core is one of main performance index of transformer.No-load performance comprises no-load loss, no-load current etc.The every index and the core volume of no-load performance unshakable in one's determination, design is made and core material has relation.
During transformer work, pass through the alternating flux of the sinusoidal variations identical in the iron core with the power supply panel rate.In the electrical steel sheet,, eddy current loss and magnetic hysteresis loss are arranged in silicon steel sheet by the alternating flux of sinusoidal variations.No-load loss is the loss in the lamination more than 99%.
No-load loss is calculated:
No-load loss=supplementary load loss coefficient * (specific loss+stem of stem and iron yoke and iron yoke weight)
How to reduce size unshakable in one's determination, just how designing a kind of loop construction is the problem that the technical staff will solve.
Summary of the invention
The utility model technical issues that need to address have provided the loop construction in a kind of transformer, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: N circle coil; The shape of described coil is the elliptical shape structure.
Compared with prior art, the beneficial effects of the utility model are: reduce material unshakable in one's determination and also reduced transformer noload losses simultaneously.
Description of drawings
Fig. 1 is the loop construction schematic diagram of transformer in the prior art;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: N circle coil 10; The shape of described coil 10 is elliptical shape structures.
With SCB9-500KVA/10KV is example, and the no-load loss of national Specification transformer is 1305W, through improving, original round coil is modified into the ellipse coil, can be reduced to 1160W to no-load loss, reaches SCB10 series.
The utility model has been dwindled the volume of coil, and original prototype coil is made into the ellipse coil, has dwindled the volume of coil like this, and the copper cash that coil is used is few.It is little to release winding volume according to the formula on background technology, and it is little to occupy the space, has also reduced transformer noload losses simultaneously at the material that reduces iron core like this.
