Description

Technical Field

[0001] This invention relates to the field of dry-type transformer equipment technology, specifically a dry-type transformer with an insulation protection mechanism. Background Technology

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, a dry-type transformer is a transformer whose core and windings are not immersed in insulating oil.

[0003] In the prior art, dry-type transformers use insulators to support and fix the busbars and live conductors, which effectively increases the creepage distance and ensures sufficient distance for insulation between live conductors or between conductors and the ground.

[0004] However, since the insulators are located above the dry-type transformer and exposed to the air without any protective measures, the moisture content of the insulators will inevitably increase in severe weather conditions such as rain, snow, and hail. If the moisture content of the insulators is too high, it will affect their insulation performance, cause flashover, and lead to transformer tripping or other faults, thus affecting their normal use. Furthermore, hail or other falling objects from heights will damage the insulators, thereby affecting their performance. Summary of the Invention

[0005] The purpose of this invention is to provide a dry-type transformer with an insulation protection mechanism to solve the problem mentioned in the background art where the insulators are located above the dry-type transformer and exposed to the air without protective measures. In severe weather conditions such as rain, snow, and hail, the moisture content of the insulators will inevitably increase. If the moisture content of the insulators is too high, it will affect their insulation performance, cause flashover, and lead to transformer tripping or other faults, thus affecting their normal use. Furthermore, hail or other falling objects from high altitudes will damage the insulators, thereby affecting their performance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dry-type transformer with an insulation protection mechanism, wherein the dry-type transformer with the insulation protection mechanism comprises:

The two sets of limiting blocks are symmetrically distributed on both sides of the slide groove, and the rubber pad abuts against the end surface of the limiting block.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention discloses a dry-type transformer with an insulating protection mechanism. The protective plate is installed by clamping it to the side of a fixed plate, positioning it above the insulator for protection. This effectively prevents contact with the insulator during rain, snow, and hail, reducing surface moisture. The clamping plate is positioned by spring elastic support, improving ease of installation and removal. The second protective plate uses elastic sheets to effectively buffer falling objects, such as hailstones, reducing the impact force and thus minimizing damage and extending service life. The inclined end face of the second protective plate effectively disperses rainwater, preventing accumulation. Spikes further enhance the second protective plate's effectiveness, preventing birds from landing on its surface and thus avoiding droppings, effectively reducing the probability of accidents.

[0026] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figures 1 to 5 The present invention provides a technical solution: a dry-type transformer with an insulation protection mechanism;

[0028] To improve the ease of installation of the protective plate 2, two sets of clamping plates 9 are provided below the protective plate 2. The inner end face of the clamping plate 9 has a groove, and a rubber strip 13 is fixed to the inner wall surface of the groove. The outer end surface of the clamping plate 9 is provided with a positioning rod 7, and a spring 8 is sleeved on the positioning rod 7. The outer end of the positioning rod 7 passes through a limiting plate 6 provided on the side wall of the protective plate 2, and the spring 8 is located between the clamping plate 9 and the limiting plate 6. The surface of the dry-type transformer body 1 is provided with a fixing plate 11, and the surface of the fixing plate 11 is provided with an insulator 10. By pulling the positioning rod 7, the clamping plate 9 is moved outward. Lateral movement is used to widen the distance between the two, and the clamping plate 9 is fitted onto both sides of the fixed plate 11. The positioning rod 7 is loosened and the clamping plate 9 is moved inward by the elasticity of the spring 8 so that it is locked onto the side of the fixed plate 11. The rubber strip 13 located on the inner side of the clamping plate 9 effectively improves the stability of its locking, thus completing the installation of the protective plate 2. At this time, the protective plate 2 is above the insulator 10 to protect it. The protective plate 2 shields the insulator 10 and effectively avoids contact with the insulator 10 in rain, snow and hail weather, thereby reducing its moisture and improving its performance.

[0029] Example 2:

[0030] Based on Embodiment 1, in order to improve the stability of the clamping plate 9 during movement and the effectiveness of the protective plate 2, a trapezoidal groove 15 is provided on the surface of the protective plate 2. A trapezoidal limiting block 14 is provided at the top of the clamping plate 9, and a rubber pad 17 is fixed in the groove 15. A bracket 12 is fixed at the end of the clamping plate 9, and the top of the bracket 12 supports the bottom surface of the protective plate 2. The limiting block 14 is located in the groove 15 to effectively improve the stability of the clamping plate 9 during movement, thereby effectively improving the engagement effect with the fixing plate 11. Both are trapezoidal, which effectively limits the protective plate 2 and prevents the protective plate 2 from detaching. The rubber pad 17 effectively increases the resistance between the limiting block 14 and the groove 15, thereby improving the stability of the protective plate 2 during use. The support 12 supports the protective plate 2 to effectively improve its strength and thus increase its protective effect.

[0031] Example 3:

[0032] In order to improve the performance of the guard plate 2, a second guard plate 3 is provided above the guard plate 2. An elastic sheet 16 is provided on the bottom surface of the second guard plate 3. The bottom end of the elastic sheet 16 is fixed to the top surface of the guard plate 2. The second guard plate 3 effectively buffers objects falling from a height through the elasticity of the elastic sheet 16, reduces the impact force generated by the object falling from a height, thereby reducing the degree of damage and improving its service life.

[0033] Example 4:

[0034] To further improve the effectiveness of the second protective plate 3 based on Embodiment 3, spikes 4 and guide rods 5 are respectively provided on the upper and lower surfaces of the second protective plate 3. The guide rods 5 penetrate through the bottom surface of the protective plate 2. The second protective plate 3 achieves its stability through the guide rods 5, preventing it from shifting during use. The end face of the second protective plate 3 is inclined, which effectively disperses rainwater and prevents rainwater from accumulating. The spikes 4 effectively improve the effectiveness of the second protective plate 3, preventing birds from landing on its surface, thereby preventing the generation of droppings and effectively reducing the probability of accidents.
