The scheme is specifically solved by the invention of a corresponding map of increase and decrease of the copper wire load area and the working temperature resistivity in a graph 4 and the invention of a formula tri-tetra-V, so that the invention of the ultra-micro loss transformer has clear and clear design conversion data, and as can be seen from the graph 4 and a conversion program, the corresponding relation between the increase percentage of the copper wire load area and the temperature resistivity shows that the smaller the resistance value and the resistivity of a winding is, the smaller the loss is, and the larger the resistance value and the resistivity of the winding is, the larger the loss is. However, the ultimate goal of people on the scientific road is zero loss, and the zero loss can be realized in the near future along with the development of super materials.)

1. The technical field is as follows:

the electric power discipline.

2. Background field:

the existing transformer loss parameter table can fully reflect that the load loss power of the transformer used in execution is large, compared with an ultra-micro loss transformer, a large amount of electric energy is lost, unnecessary electric energy is wasted in a long period of time, and huge economic loss is caused.

fig. 1 is a theoretical principle diagram of a transformer (a three-phase transformer structure principle diagram), fig. 2 is a transformer set iron core combination diagram (a four-frame five-column type amorphous alloy iron core structure diagram), and fig. 3 is a single iron core structure diagram (an amorphous alloy single iron core). FIG. 4 is a graph showing the increase and decrease of the copper wire loading area and the working temperature resistivity. Table 1. table of loss parameters of the current transformer; table 2. resistance table of copper wires at different temperatures; table 3. current, wire diameter and copper wire temperature meter; table 4 shows the parameter comparison table of the current transformer and the ultra-micro loss transformer.

The main principle of the power transformer is the magnetoelectric coupling principle, the magnetic conduction part mainly comprises an iron core, and the electric conduction part mainly comprises a winding. The transformer supplies power to people, and simultaneously has the problem of self loss, mainly comprising no-load loss and load loss, wherein the no-load loss is generated by iron core eddy current of a magnetic material, and is called iron loss WFe for short; the load loss is generated by the winding wire, which is called copper loss WCu for short.

The iron loss is caused by different amounts and materials of magnetic conductive materials, the generated eddy currents are different in size, namely the iron loss is different, the more the magnetic conductive materials are, the larger the iron loss is, the less the magnetic conductive materials are, the smaller the iron loss is, and due to the design and invention of the ultramicro-loss transformer, the magnetic conductive materials are amorphous thin strips with the same length as the circumference of the iron core. The ultramicro loss transformer winding increases a certain thickness compared with the existing transformer winding, the thickness increases the length of the amorphous belt under the condition of a certain proportion, and the increased length percentage is equal to the increased value percentage of no-load loss.

The copper loss is caused by different sizes of the cross sections of the wires and different sizes of the resistivity of the wires caused by temperature, and the length and the carrying area of the wires, so that the resistance value and the resistivity of the whole winding are changed, the larger the resistance value and the resistivity is, the larger the copper loss is, and the smaller the resistance value and the resistivity is, the smaller the copper loss is. The copper loss coefficient is 9, and the copper loss coefficient has three components: 4/9 is the copper loss ratio of the high-voltage winding; 2/9 is the copper loss ratio of the low-voltage winding; temperature loss ratio 3/9. When the existing transformer runs at full load, the central temperature of a winding is between 100 and 170 ℃, the average temperature is 135 ℃, the resistivity of a copper wire is increased from 0.0172 at 10 ℃ to 0.0258, the increase is 50 percent, and simultaneously, the load loss is increased to a value corresponding to the percent, the increased value is referred to as temperature loss wt degrees for short, the percentage of increase of the sectional area of a winding lead is also corresponding to temperature reduction percent, the percentage of temperature reduction is also corresponding to the percentage of resistivity reduction, the percentage of resistivity reduction is also corresponding to the percentage of reduction of the load loss, and the reduced value is referred to as temperature reduction energy saving value-wt degrees for short.

5. The specific implementation mode is as follows:

the method mainly comprises the steps of carrying out one-time new design on related data of a transformer winding, converting a set of new lead data to reduce the resistance value and the resistivity of the winding, wherein the smaller the resistance value and the resistivity is, the smaller the loss is, and therefore the optimal set value of the ultra-micro loss transformer is shown in a table 4, and the detailed content of the optimal set value is shown in an ultra-micro loss transformer conversion program.
