Description

Technical Field

[0001] This utility model relates to the field of transformer equipment technology, and in particular to a frequency conversion transformer structure. Background Technology

[0002] A frequency converter transformer is a device that uses power electronics technology to convert alternating current (AC) frequency. Its core function is to convert a fixed-frequency input voltage into an adjustable-frequency output voltage, while also allowing for voltage amplitude adjustment as needed. Its working principle is based on rectification, filtering, and inversion: first, a rectifier converts the mains frequency AC power into DC power; then, an inverter converts the DC power into AC power with an adjustable frequency. Some models also integrate voltage transformation functionality. Frequency converter transformers are widely used in industrial motor speed control, grid connection of new energy power generation, rail transit traction systems, and electric vehicle charging facilities, with significant advantages, especially in scenarios requiring high-efficiency energy-saving control. During use, frequency converter transformers require heat dissipation.

[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0022] To address the problems existing in the background technology, this application proposes the following technical solution: a frequency converter transformer structure, including a transformer body 1, one side of which is an open structure, and multiple sets of horizontal plates 2 are fixedly connected at the opening, with gaps between the horizontal plates 2, and symmetrical adjustment plates 7 are arranged in the gaps, the gaps being used to dissipate heat from the transformer body 1, and an adjustment component being provided outside the transformer body 1, the adjustment component being used to drive the opposing adjustment plates 7 to move synchronously towards or away from each other.

[0023] To facilitate movement, casters 3 are installed around the bottom of the transformer body 1. The transformer body 1 has heat dissipation vents on the outside and a cooling fan installed inside.

[0024] In a further design, a fixing frame 4 is fixedly connected to the outside of the transformer body 1. A guide rod 5 is fixedly connected to the fixing frame 4. A connecting plate 17 is sleeved on the outside of the guide rod 5. The guide rod 5 passes through the connecting plate 17. A spring 6 is sleeved on the outside of the guide rod 5. The two ends of the spring 6 are respectively connected to the connecting plate 17 and the fixing frame 4. A first pull rope 8 is fixedly connected to the outside of the connecting plate 17. A second pull rope 9 is fixedly connected to the outside of the first pull rope 8. A mounting frame 10 is fixedly connected to the outside of the transformer body 1. A steering wheel is rotatably connected in the mounting frame 10. A guide wheel 11 is also installed on the outside of the transformer body 1. The second pull rope 9 passes through the steering wheel and the guide wheel 11. The steering wheel and the guide wheel 11 are used to guide the second pull rope 9.

[0025] In the specific design, the adjustment component includes a bidirectional threaded rod 15 and a motor 13. A fixed plate 12 is fixedly connected to the top of the transformer body 1. The bidirectional threaded rod 15 is rotatably connected to the fixed plate 12. The motor 13 is fixedly connected to the fixed plate 12. The output end of the motor 13 is fixedly connected to the bidirectional threaded rod 15. Two nut blocks 16 are connected to the external thread of the bidirectional threaded rod 15. The motor 13 drives the bidirectional threaded rod 15 to rotate. The bidirectional threaded rod 15 drives the two nut blocks 16 to slide towards each other. Thus, the nut blocks 16 can pull the second pull rope 9. The second pull rope 9 pulls the first pull rope 8. The first pull rope 8 pulls the connecting plate 17 to slide. The connecting plate 17 drives the adjusting plate 7 to slide. Thus, the opposing adjusting plates 7 can slide away from each other. Thus, the gap between the horizontal plates 2 can be opened to accelerate the heat dissipation inside the transformer body 1. A limit rod 14 is fixedly connected to the outside of the fixed plate 12. The limit rod 14 passes through the nut block 16. The nut block 16 is fixedly connected to the second pull rope 9.

[0026] The method of using this utility model is as follows:

[0027] When it is necessary to accelerate the heat dissipation of the transformer body 1, simply start the motor 13. The motor 13 drives the bidirectional threaded rod 15 to rotate, and the bidirectional threaded rod 15 drives the two nut blocks 16 to slide towards each other. Thus, the nut blocks 16 can pull the second pull rope 9, the second pull rope 9 pulls the first pull rope 8, and the first pull rope 8 pulls the connecting plate 17 to slide. The connecting plate 17 drives the adjusting plate 7 to slide, so that the opposing adjusting plates 7 can slide away from each other, thereby opening the gap between the horizontal plates 2 and accelerating the heat dissipation inside the transformer body 1.

[0028] After the heat dissipation is completed, the reverse start motor 13 starts working, so that the nut block 16 slides in opposite directions and no longer stretches the second pull rope 9. As a result, the adjusting plate 7 will slide in opposite directions under the elastic force of the spring 6, sealing the gap between the horizontal plates 2.

[0029] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
