Description

Technical Field

[0001] This invention relates to the field of transformer equipment technology, specifically to low-loss insulated transformers. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core. In electrical equipment and wireless circuits, it is commonly used for voltage step-up and step-down, impedance matching, and safety isolation. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electromotive force can be induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the number of magnetic fluxes linked to the coil changes. This is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance.

[0003] Patent application CN201810019457.5 discloses a low-loss dry-type transformer, including a core, coils, clamps, etc. The coils include low-voltage coils and high-voltage coils. The core is composed of an upper yoke, a lower yoke, an upper clamp, a lower clamp, a side screw, and a pull plate. Multiple concave heat dissipation slots are provided on the upper clamp corresponding to the coil positions. Comb-shaped support bars are used to open up the ventilation channels inside the coils. The transformer also includes an external ventilation and dustproof cover, which is divided into a top plate, a middle section, and a bottom plate. The middle section of the cover is provided with multiple air inlet windows, and the air inlet windows are provided with a multi-layer filter structure. An automatic dust shaking mechanism is provided on the multi-layer filter structure to reduce transformer losses, improve the transformer's ventilation and dustproof performance, and effectively promote energy saving.

[0004] When existing equipment malfunctions, most of the damage occurs at the transformer windings. Therefore, during repairs, it is often necessary to replace or repair the transformer windings. However, during maintenance, a large number of fasteners need to be disassembled layer by layer to replace the windings. The narrow operating space further increases the difficulty of maintenance and often consumes a lot of time. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a low-loss insulation transformer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-loss insulated transformer, including a housing, wherein a heat dissipation groove is formed on the outer wall of the housing, a notch is formed at the front end of the housing, a cover plate is rotatably connected to the inner wall of the notch via a bearing, a connecting plate is fixedly connected to the top of the inner wall of the housing, a pressure plate is fixedly connected to the bottom of the connecting plate, a energizing plate is fixedly connected to the bottom of the connecting plate, and a positioning assembly is movably connected to the inner wall of the housing, and further comprising:

[0007] The placement mechanism includes a track fixedly connected to the inner wall of the outer casing. A movable seat is movably connected to the outer wall of the track.

An elastic component three is fixedly connected to the inner wall of the slot hole, and the end of the elastic component three away from the slot hole is fixedly connected to the groove two. The movement of the movable column one plays the role of controlling the locking state of the placement mechanism. By setting the locking component, when the staff completes the winding maintenance, the component can quickly trigger automatic locking, effectively simplifying the manual operation process, ensuring tight coupling between the winding and the conductive interface, thereby improving maintenance efficiency and enhancing the stability of equipment operation, and avoiding the problems of poor contact or mechanical loosening that may occur with traditional fixing.

[0014] According to the above technical solution, the inner wall of the hollow groove is rotatably connected to a connecting rod via a bearing. The end of the connecting rod away from the hollow groove is fixedly connected to a movable column two. The outer wall of the movable column two is movably connected to a through hole.

[0038] The movable component 2 includes a cross plate 207, the outer wall of which is movably connected to a limiting plate 308. A first energizing head 208 is fixedly connected to the bottom of the cross plate 207, and the inner wall of the first energizing head 208 is movably connected to a second energizing head 3014. A transformer winding 201 is fixedly connected to the top of the cross plate 207, which is used to limit the position of the transformer winding 201. A lifting plate 202 is fixedly connected to the top of the transformer winding 201, and a notch 205 is provided at the top of the lifting plate 202.

At this time, the pressure plate 105 will apply a downward pressure to the force-bearing plate 203, and the energizing plate 106 will be clamped between the two elastic plates 206 by the elastic force of the elastic plate 206 itself.

[0039] The positioning component 11 includes a locking post 111.

The energized ring 3013 is used to connect the circuit between the outside and the transformer winding 201. When the movable seat 306 is pushed in along the track 301, the locking component 32 will automatically embed into the circular hole 304, and the energized ring 3013 will embed into the energized groove 305.

[0041] The pulling component 31 includes a sliding rod 311. The outer wall of the sliding rod 311 is movably connected to the U-shaped groove 3010. A force-bearing plate 313 is fixedly connected to the outer wall of the sliding rod 311. An elastic component 312 is fixedly connected to the inner wall of the sliding rod 311. The end of the elastic component 312 away from the sliding rod 311 is fixedly connected to the movable seat 306. A connecting plate 314 is fixedly connected to the end of the sliding rod 311 away from the elastic component 312. A U-shaped plate 315 is fixedly connected to the outer wall of the connecting plate 314. When the movable component 2 needs to be replaced, as the operator pulls the U-shaped plate 315, the force-bearing plate 313 on the sliding rod 311 will move together through the connecting plate 314. The moving force-bearing plate 313 will change the state of the locking component 32, thereby releasing the lock of the locking component 32.

[0042] The locking assembly 32 includes a movable column 321, the outer wall of which is movably connected to a groove 309 and a circular hole 304. A hollow groove 322 is formed on the outer wall of the movable column 321. A slot 325 is formed at the end of the movable column 321 away from the inclined plate 303. An elastic component 327 is fixedly connected to the inner wall of the slot 325. The end of the elastic component 327 away from the slot 325 is fixedly connected to the groove 309. The movement of the movable column 321 controls the locking state of the placement mechanism 3. The inner wall of the hollow groove 322 is rotatably connected to a bearing. The connecting rod 323 has a movable column 324 fixedly connected to one end away from the hollow groove 322. The outer wall of the movable column 324 is movably connected to the through hole 3011. The end of the movable column 324 away from the movable seat 306 is fixedly connected to a force plate 326. As the force plate 313 moves, it drives the force plate 326 to move as well. The moving force plate 326 will drive the movable column 324 to move. The moving force plate 324 will drive the connecting rod 323 to deflect. Then, the deflection of the connecting rod 323 will cause the movable column 321 to move outward, thereby releasing the lock of the movable seat 306.
