Description

Technical Field

[0001] This utility model relates to the field of power transformer technology, specifically a high-voltage connection device for a dry-type power transformer. Background Technology

[0002] A dry-type power transformer is a type of electrical equipment that does not rely on insulating oil for cooling and insulation. Its core and windings are directly exposed to the air or wrapped with solid insulating materials, and are cooled by natural convection or forced air. The high-voltage connection device of a dry-type power transformer is a key component used to achieve a safe and reliable electrical connection between the high-voltage side cable and the internal windings of the transformer.

[0003] Announcement No. CN222145936U discloses a high-voltage connection device for a dry-type power transformer. This patent addresses the shortcomings of existing connection devices, which have fixed dimensions and cannot be adjusted according to actual needs during use, making it difficult to adapt to different specifications of dry-type power transformers. By using a fixing plate in conjunction with fixing holes of different heights, the installation height of the support frame can be changed, thereby enabling the connection device to adapt to different specifications of dry-type transformers.

[0004] However, when adjusting the height of the support frame, the operator needs to remove two fixing bolts, hold the support frame while adjusting its height, and use an installation tool to install one of the fixing bolts into the designated fixing hole to initially fix the support frame after adjustment. At the same time, the operator also needs to remove and install the other fixing bolt. The operation process is cumbersome, resulting in poor convenience of installation and adjustment, and affecting the adjustment efficiency of the support frame. Therefore, a high-voltage connection device for dry-type power transformers is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-voltage connection device for dry-type power transformers, which has the advantage of high adjustment efficiency. It solves the problem that existing high-voltage connection devices require both holding the support frame to adjust its height and holding the installation tool to install the fixing bolts during the adjustment process, which is cumbersome and results in poor convenience of installation and adjustment, affecting the adjustment efficiency of the support frame.

[0006] To achieve the aforementioned goal of high adjustment efficiency, this utility model provides the following technical solution: a high-voltage connection device for a dry-type power transformer, comprising a hollow movable plate and two fixed supports, wherein a vertical adjustment fixing component is provided between the hollow movable plate and the fixed supports, and a horizontal adjustment component is provided on the hollow movable plate;

[0007] The vertical adjustment fixing assembly includes a rectangular sleeve fixedly installed on the surface of the hollow movable plate, a fixing plate and two top springs fixedly installed inside the rectangular sleeve, and a fixing rack plate fixedly installed on the surface of the fixing bracket.

[0008] The lateral adjustment assembly includes a partition plate fixedly installed inside the hollow moving plate. Two tension springs are fixedly installed on the opposite side surface of the partition plate. An adjustment plate extending through the hollow moving plate is fixedly installed at one end of each tension spring. An adjustment threaded rod is rotatably installed on the side surface of the hollow moving plate. An arc-shaped spring is threadedly connected to the surface of the adjustment threaded rod. Both ends of the arc-shaped spring extend into the hollow moving plate and are rotatably connected to the adjustment plate.

[0009] Furthermore, a sliding plate is fixedly installed at one end of the top spring, and a groove is provided on the surface of the fixed bracket, with the sliding plate located in the groove.

[0010] Furthermore, the fixed bracket has two fixing holes on its surface, which are symmetrically distributed on the surface of the fixed bracket.

[0011] Furthermore, the rectangular sleeve is fitted onto the surface of the fixed bracket, the inner width of the rectangular sleeve is adapted to the outer width of the fixed bracket, and the fixed clamping plate and the fixed rack plate correspond to each other.

[0012] Furthermore, the hollow movable plate has two strip-shaped holes on its surface that are connected to the interior of the hollow movable plate, and the arc-shaped spring is located inside the strip-shaped holes.

[0013] Furthermore, terminals are fixedly installed on the surfaces of both the hollow moving plate and the adjusting plate.

[0014] Compared with the prior art, this utility model provides a high-voltage connection device for a dry-type power transformer, which has the following advantages:

[0015] The high-voltage connection device of this dry-type power transformer uses a rectangular sleeve inner top spring to push a sliding plate to slide within the groove of a fixed bracket, allowing the fixed clamping plate and the fixed rack plate to flexibly engage and disengage. Workers can easily adjust the relative height between the hollow moving plate and the fixed bracket without disassembling or installing the fixing bolts. In the lateral adjustment assembly, rotating the adjusting threaded rod moves an arc-shaped spring within a slotted hole, thereby pulling the adjusting plate to overcome the tension spring force and achieve lateral position adjustment. The tension spring provides stable rebound force, ensuring a stable and reliable position after adjustment. This simplifies the adjustment process of the hollow moving plate and the adjusting plate, effectively improving the adjustment efficiency of the support frame. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The high-voltage connection device of a dry-type power transformer in this embodiment includes a hollow movable plate 1 and two fixed supports 2. A vertical adjustment and fixing component 3 is provided between the hollow movable plate 1 and the fixed supports 2, and a horizontal adjustment component 4 is provided on the hollow movable plate 1.

[0024] The vertical adjustment fixing assembly 3 includes a rectangular sleeve 31 fixedly installed on the surface of the hollow moving plate 1. A fixing plate 32 and two top springs 33 are fixedly installed inside the rectangular sleeve 31. A fixing rack plate 34 is fixedly installed on the surface of the fixing bracket 2. The horizontal adjustment assembly 4 includes a partition 41 fixedly installed inside the hollow moving plate 1. Two tension springs 42 are fixedly installed on the opposite side surface of the partition 41. An adjustment plate 43 extending through to the outside of the hollow moving plate 1 is fixedly installed at one end of each tension spring 42. An adjustment threaded rod 44 is rotatably installed on the side surface of the hollow moving plate 1. An arc-shaped spring piece 45 is threadedly connected to the surface of the adjustment threaded rod 44. Both ends of the arc-shaped spring piece 45 extend into the hollow moving plate 1 and are rotatably connected to the adjustment plate 43.

[0025] In this embodiment, a sliding plate 35 is fixedly installed at one end of the top spring 33. A groove 36 is provided on the surface of the fixed bracket 2. The sliding plate 35 is located in the groove 36, which facilitates the sliding plate 35 to move in a straight line along the groove 36 during the extension and retraction of the top spring 33, and can prevent the top spring 33 from shifting or deforming when subjected to force.

[0026] In this embodiment, the surface of the fixed bracket 2 is provided with two fixing holes 5, which are symmetrically distributed on the surface of the fixed bracket 2. By setting the fixing holes 5, it is easy to fix the fixed bracket 2 in a designated position.

[0027] In this embodiment, the rectangular sleeve 31 is fitted onto the surface of the fixed bracket 2. The inner width of the rectangular sleeve 31 is adapted to the outer width of the fixed bracket 2. The fixed clamping plate 32 and the fixed rack plate 34 correspond to each other, which helps to ensure the stability of the rectangular sleeve 31 when it moves on the surface of the fixed bracket 2.

[0028] In this embodiment, the hollow moving plate 1 has two strip holes 6 on its surface that are connected to the interior of the hollow moving plate 1. The arc-shaped spring piece 45 is located in the strip hole 6. By setting the strip hole 6, space can be reserved for the movement of the arc-shaped spring piece 45, which facilitates the movement of the arc-shaped spring piece 45 on the hollow moving plate 1.

[0029] In this embodiment, terminals 7 are fixedly installed on the surfaces of both the hollow movable plate 1 and the adjusting plate 43.

[0030] The working principle of the above embodiments is as follows:

[0031] When height adjustment is required, the hollow moving plate 1 is pulled away from the fixed bracket 2, compressing the top spring 33 and separating the fixed clamping plate 32 from the fixed rack plate 34 on the fixed bracket 2. At this time, the hollow moving plate 1 can be moved up and down, the rectangular sleeve 31 moves synchronously, and the slide plate 35 slides in the slide groove 36. After adjusting to the appropriate height, the hollow moving plate 1 is released, the top spring 33 is reset, and the fixed clamping plate 32 is pushed to re-engage with the fixed rack plate 34, thus completing the height fixation. When adjusting the adjusting plate 43, the adjusting threaded rod 44 is rotated, and the arc-shaped spring piece 45 moves axially along the adjusting threaded rod 44, pulling the adjusting plate 43 to overcome the elastic force of the tension spring 42, so that the adjusting plate 43 can extend and retract within the hollow moving plate 1 to achieve lateral position adjustment. The tension spring 42 provides stable rebound force, and the arc-shaped spring piece 45 provides support force, thus ensuring that the position of the adjusting plate 43 is stable and reliable after adjustment.

[0032] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and the existing publicly available power connection technologies are not described in detail in the text.
