[0034] In this embodiment, the main components of the transformer in the display model, including the bushing, oil tank 6, cooler, body, tap changer, outlet device, etc., are designed using the principle of proportional scaling to truly restore the actual product structure and relative position.

The upper transparent part is made of transparent acrylic material, and the structure inside the winding and the simulation effects of electricity and magnetism can be displayed through the upper transparent part.

[0035] In this embodiment, the left winding 100 is cut into sections to mainly show the winding cross section, and the right winding 200 is a transparent structure to show the current flow on the grid side and the valve side. The current enters from the first valve side bushing 32, flows through the left and right coils, and then exits from the second valve side bushing 33. The transformer is all alternating current.

[0036] The actual structure of a typical transformer is that the composition and arrangement of the windings on the left and right sides are the same. From the core column to the inside of the oil tank 6, there are the voltage regulating winding, the grid side winding 51, and the valve side winding 52. The regulating, grid, and valve windings of the left and right columns are connected in parallel.

[0049] The grid-side current is controlled to simulate the lighting of the LED light strip, simulating that according to the law of electromagnetic induction, the flow of grid-side current generates a main magnetic flux in the iron core, and the main magnetic flux induces a valve-side current in the valve-side winding 52 (the green LED light is on). The valve-side current flows through the first valve-side sleeve 32, through the first valve-side outlet device 41, the valve-side winding 52, the second valve-side outlet device 42, and the second valve-side sleeve 33, to form a valve-side current loop.

[0052] A longitudinal LED light strip distributed along the circumference of the core column is arranged on the outside of the core column to simulate the flow effect of the leakage magnetic flux.

[0053] Furthermore, a first temperature rise simulation light strip 24 is provided on the upper iron yoke of the core of each winding of the display model, and a second temperature rise simulation light strip 25 is provided in the lower iron yoke of the core, so as to simulate the local temperature rise of different parts of the core.

[0054] The first temperature rise simulation light strip 24 and the second temperature rise simulation light strip 25 are both multi-color light strips, which are used to simulate the local temperature rise conditions of different parts of the iron core, including:

[0055] The first temperature rise simulation light strip 24 and the second temperature rise simulation light strip 25 are controlled to change colors to simulate the leakage magnetic field causing eddy current loss in the iron core and the iron yoke, causing the iron core to heat up.

[0058] refer to Figure 3 Each LED light strip can be controlled by PLC programming. The working principle of the light simulation control circuit is as follows:

[0059] 1. Turn on the power supply of the LED light control circuit, and control the current on the valve side to simulate the LED light strip lighting up, and simulate the current flow on the grid side. The current flows through the grid side high-voltage bushing 31, the grid side winding 51, and the grid side neutral point bushing 34 to form a grid side current loop;

[0060] 2. Control the magnetic circuit simulation light strip 21 to light up, simulating that according to the law of electromagnetic induction, the flow of grid-side current generates the main magnetic flux in the iron core and the leakage magnetic flux around the winding;

[0061] 3. The control grid-side current simulates the LED light strip to light up. According to the electromagnetic induction law, the main magnetic flux induces the valve-side current in the valve-side winding 52. The valve-side current flows through the first valve-side sleeve 32, the first valve-side outlet device 41, the valve-side winding 52, the second valve-side outlet device 42, and the second valve-side sleeve 33 to form a valve-side current loop.

Control the changes of the multi-color LED lights of the first temperature rise simulation light strip 24 and the second temperature rise simulation light strip 25 to simulate the leakage magnetic field causing eddy current loss in the iron core and the iron yoke, so that the iron core is heated. The temperature varies according to the different positions of the iron core and the iron yoke, and the temperature distribution cloud map is displayed by the multi-color LED lights (cold colors indicate low temperature positions, and warm colors indicate high positions);

[0063] 5. By touching the relevant components, the function introduction, basic structure, key parameters, application scenarios and other information of the component will be displayed on the display.

[0064] Through the visual simulation of the above-mentioned transformer electrical circuit, magnetic circuit and temperature distribution, the linked display of current flow path, magnetic field change and temperature distribution is realized, and the flow direction and timing of the electric field and magnetic field satisfy the law of electromagnetic induction, thereby realizing the visual display technology of the transformer electrical circuit, magnetic circuit and temperature distribution.

Visitors can deepen their memory and understanding of abstract knowledge points through visual observation and operation, and improve the popularization and display effect of the product. The model can be used as a working scenario for displaying scientific research results, physical teaching, product exhibitions, etc., and the method can be applied to the structure and principle display of similar equipment.

[0066] Compared with the static appearance display of traditional models, this invention can visualize complex physical processes and abstract physical concepts such as transformer magnetic field distribution and changes, primary (grid side) winding, secondary (valve side) winding current conversion, temperature distribution, etc., and display the working principle of the transformer more intuitively and clearly, breaking the limitations of abstract concepts and allowing people to understand the transformer, an important electrical equipment, more intuitively and deeply.

[0067] The beneficial effects can be seen as follows:

[0068] 1. Solve the problem of visualizing the internal structure of conventional equipment models by using transparent shells and dissecting internal components for three-dimensional interface display;

[0069] 2. Solve the problem of visual display of current flow in transformer bushings, windings, and tap switches. Use LED light strips, transparent acrylic, and hot-processing molding. Use PLC program to control the light and simulate the current flow direction and velocity.

Use transparent acrylic heat processing to form with built-in LED light strip, use PLC program to control the light, and simulate the magnetic field distribution and flow direction;

[0071] 4. To solve the problem of visual display of temperature distribution, color-variable LED lights are used. Through PLC programming, the colors of different parts of the LED lights built into the iron core can be changed to simulate the temperature rise in different areas of the upper and lower yokes of the iron core.
