DETAILED DESCRIPTION
[0025] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, identical elements are represented by identical or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.
[0026] like Figures 1 to 3 As shown, the utility model provides a display model of a typical converter transformer and its key components, and the display model is used to simulate a typical converter transformer. The right winding 200 of the display model has a bottom cross-sectional portion and an upper transparent portion arranged on the bottom cross-sectional portion. The right winding 200 is provided with a mesh and a valve-side current simulation light strip for simulating the flow of current in the right winding 200, and the mesh and valve-side current simulation light strip are displayed through the upper transparent portion; the iron core of the right winding 200 has a half-cut structure, forming a half-cut iron core, and the half-cut iron core is provided with a magnetic circuit simulation light strip 21 for simulating the flow effect of the main magnetic flux; the outside of the right core column is provided with an LED light strip arranged longitudinally along the circumference of the core column for simulating the flow effect of leakage magnetic flux.
[0027] In this embodiment, the core of the left winding 100 also has a half-split structure.
[0028] In this embodiment, the main components of the transformer in the display model, including the bushing, oil tank 6, cooler, transformer body, tap changer, and outlet device, are designed using the principle of proportional scaling to faithfully reproduce the actual product structure and relative positions. One side wall of the oil tank 6 along its longitudinal axis is made of transparent material, forming a transparent sidewall to facilitate display of the internal structure of the transformer tank 6. The upper transparent portion is made of transparent acrylic material, which allows the internal structure of the winding to be displayed, as well as the simulated effects of electricity and magnetism.
[0029] 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.
[0030] 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 respectively a voltage regulating winding, a grid side winding 51, and a valve side winding 52. The regulating, grid, and valve windings on the left and right columns are then connected in parallel.
[0031] The grid-side and valve-side current simulation light strips within the right winding 200 are spiral LED water-flow light strips. The spiral LED water-flow light strips include an inner grid-side current simulation LED light strip 22 and an outer valve-side current simulation LED light strip 23. The grid-side current simulation LED light strip 22 is red, and the valve-side current simulation LED light strip 23 is green.
[0032] Furthermore, the grid-side and valve-side current simulation light strips extend into the leads and corresponding bushings of the left and right windings 200, and the leads and bushings are at least partially transparent. By controlling the flow direction of the spiral LED water-flow light strips, the flow of grid-side current and valve-side current into the windings from the grid-side bushings (including the grid-side high-voltage bushing 31 and the grid-side neutral bushing 34) and the valve-side bushings (including the first valve-side bushing 32 and the second valve-side bushing 33) on both sides is displayed.
[0033] The flow directions of the control grid and valve-side current simulation light strips are respectively displayed: the grid-side current flows through the grid-side high-voltage bushing 31 into the grid-side winding 51 and then to the grid-side neutral point bushing 34 (red light strip); and the valve-side current flows through the first valve-side bushing 32 into the valve-side winding 52 and then to the second valve-side bushing 33 (green).
[0034] In this embodiment, the magnetic circuit simulation light strip 21 is a blue LED light strip, and the main magnetic flux effect is displayed by controlling the flow direction of the magnetic circuit simulation light strip 21. A longitudinal LED light strip distributed along the circumference of the core column is set on the outside of the core column to simulate the flow effect of the leakage magnetic flux.
[0035] Furthermore, red background light strips may be built into the left and right windings 200 and their cores to simulate temperature rise using virtual light.
[0036] Furthermore, the display model features a first temperature-rise simulation light strip 24 on the upper yoke of each winding core, and a second temperature-rise simulation light strip 25 within the lower yoke of the core, to simulate localized temperature rises in different parts of the core. Specifically, the temperature distribution display features four-color variable LED lights. PLC programming allows the colors of the LED lights within the core to change, simulating temperature rises in different areas of the upper and lower yokes, side yokes, and core, providing a temperature distribution display.
[0037] like Figure 3 As shown, the light simulation control circuit includes a DC power supply, a first LED controller, a second LED controller and an LED magic color controller. The DC power supply is a 12V DC power supply, which is used to connect the light simulation control circuit to a 220V AC power supply and convert the AC power supply into 12V DC power. The first LED controller, the second LED controller and the LED magic color controller are electrically connected to the DC power supply respectively, the valve side current simulation LED light strip and the grid side current simulation LED light strip are both electrically connected to the first LED controller, the magnetic circuit simulation light strip 21 is electrically connected to the second LED controller, the first temperature rise simulation light strip 24 and the second temperature rise simulation light strip 25 are both electrically connected to the LED magic color controller, and the changes of each LED light are controlled by PLC programming.
[0038] Furthermore, touch buttons are provided on each component, which are electrically connected to the controller of the display mode, which is in turn electrically connected to the display screen. By touching the relevant component, the display screen displays information such as the component's function introduction, basic structure, key parameters, and application scenarios.
[0039] refer to Figure 3 , each LED light strip can be controlled by PLC programming, and the working principle of the light simulation control circuit is as follows:
[0040] 1. Turn on the power supply of the LED lighting control circuit. The current on the control valve side simulates the LED light strip lighting up and the grid side current flow. The current flows through the grid side high-voltage bushing 31, the grid side winding 51, and the grid side neutral point bushing 34, forming a grid side current loop.
[0041] 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 main magnetic flux in the iron core and leakage magnetic flux around the winding;
[0042] 3. The grid-side current simulation LED light strip lights up, simulating the main magnetic flux inducing a valve-side current in the valve-side winding 52 according to the law of electromagnetic induction. The valve-side current flows through the first valve-side bushing 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 bushing 33, forming a valve-side current loop.
[0043] 4. Control 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 eddy current loss caused by leakage magnetic field in the iron core and iron yoke, causing the iron core to heat up. The temperature varies depending on the position of the iron core and 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 temperature positions);
[0044] 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.
[0045] Through the above-mentioned visual simulation of the transformer's electrical circuit, magnetic circuit, and temperature distribution, the linked display of current flow path, magnetic field changes, 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's electrical circuit, magnetic circuit, and temperature distribution.
[0046] The display model of a typical converter transformer and its key components in this application visualizes the transformer's complex internal structure, the abstract electromagnetic coupling working principle, and the unevenly distributed temperature of the transformer body during operation. Visitors can deepen their memory and understanding of abstract knowledge points through visual observation and operation, thereby improving the product's popular science publicity and display effects. This model can be used as a working scenario for displaying scientific research results, physical teaching, product exhibitions, and other work scenarios. This method can be applied to the structure and principle display of similar equipment.
[0047] Compared with the static appearance display of traditional models, this utility model can visualize complex physical processes and abstract physical concepts such as the transformer magnetic field distribution and changes, primary (grid side) winding and secondary (valve side) winding current conversion, and temperature distribution. It can more intuitively and clearly display the working principle of the transformer, break the limitations of abstract concepts, and allow people to understand the transformer, an important electrical equipment, more intuitively and deeply.
[0048] The beneficial effects can be referred to as follows:
[0049] 1. Solve the problem of visualizing the internal structure of conventional equipment models by using transparent shells and dissecting internal components for 3D interface display;
[0050] 2. To solve the problem of visual display of current flow in transformer bushings, windings, and tap changers, LED light strips are formed by heat-processing transparent acrylic, and PLC program is used to control the lights to simulate the direction and velocity of current flow;
[0051] 3. Solve the problem of visual display of the main magnetic flux and leakage magnetic flux distribution in the core and space. Use transparent acrylic heat-processed molding with built-in LED light strips, use PLC program to control the lights, and simulate the magnetic field distribution and flow direction;
[0052] 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.
