Description

Technical Field

[0001] This utility model relates to the field of voltage transformer technology, specifically to a support structure for partial discharge treatment of voltage transformers. Background Technology

[0002] A voltage transformer is an electrical device that converts high voltage to low voltage proportionally. Its core is a transformer with an iron core, which mainly consists of a primary winding, a secondary winding, an iron core, and insulation.

[0003] Before the voltage transformer housing is filled with epoxy resin, a support frame needs to be assembled to support the windings. Traditional frames use a fixed length; if the length is too long, it needs to be cut; if the length is too short, it needs to be welded to extend it. This undoubtedly increases the complexity of the assembly process and thus affects assembly efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a voltage transformer partial discharge treatment support structure that does not rely on the traditional method of welding to lengthen when it is too short or cutting when it is too long for installation. This structure increases assembly adaptability, simplifies operation, and improves assembly efficiency, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a voltage transformer partial discharge treatment support structure, comprising two support rods, which are placed horizontally and on the same horizontal line. The bottom of the adjacent ends of the two support rods are fixedly connected with fitting iron plates for fixing the windings. The top of the outer end of the support rod is fixed with a support round screw sleeve. The top of the support round screw sleeve is threadedly connected with an adjusting screw. The top of the adjusting screw is fixedly connected with an embedded sleeve for supporting the top of the inner shell of the voltage transformer.

[0006] Preferably, the adjusting screw and the embedded sleeve are integrally formed, and the outer wall of the embedded sleeve is provided with anti-slip texture.

[0007] Preferably, the outer wall of the adjusting screw is provided with scale lines.

[0008] Preferably, the bonding iron sheet is arc-shaped in the side view and is welded to one end of the support rod.

[0009] Preferably, the support rod is perpendicular to the support threaded sleeve, and the outer end of the support rod is welded to the bottom end of the support threaded sleeve.

[0010] Preferably, a locking nut is threaded onto the outer wall of the adjusting screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Firstly, regarding structural stability, two horizontally placed support rods form a rigid connection base through a bottom-fitting iron plate. This base can be installed inside the voltage transformer housing, with the iron plate contacting the top surface of the winding, ensuring the overall structural stability in the horizontal direction. This allows for support and the insertion of epoxy resin filler for sealing. Simultaneously, the support threaded sleeve serves as a vertical positioning element. Its top-threaded adjusting screw provides a precise vertical positioning reference for the winding, resulting in more accurate support of the winding top height. This eliminates the need for traditional methods of welding to extend shorter sections or cutting longer sections, increasing assembly adaptability, simplifying operation, and improving assembly efficiency.

[0013] In terms of connection method and strength, the iron sheet is arc-shaped when viewed from the side and is welded to one end of the support rod. The arc-shaped design can better fit with the outer surface of the voltage transformer, increase the contact area, and provide a more stable and reliable support.

[0014] Regarding component stability assurance, the locking nut threaded on the outer wall of the adjusting screw can effectively limit the axial movement of the adjusting screw after it is rotated to the appropriate position and tightened. This prevents the adjusting screw from loosening or shifting due to external forces during the partial discharge treatment of the voltage transformer, thus ensuring the stability of the relative positions of all components in the entire support structure.

[0019] 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.

[0020] Please see Figures 1 to 3The diagram shows a voltage transformer partial discharge treatment support structure, which includes two support rods 1. The two support rods 1 are placed horizontally and on the same horizontal line. The bottom of the adjacent ends of the two support rods 1 are fixedly connected to the fitting iron plate 3 for fixing the winding 8. The top of the outer end of the support rod 1 is fixedly connected to the support round screw sleeve 2. The top of the support round screw sleeve 2 is threadedly connected to the adjusting screw 4. The top of the adjusting screw 4 is fixedly connected to the embedded bushing 5 for supporting the top of the inner part of the voltage transformer housing 10.

[0021] It is worth noting that the two horizontally placed support rods 1 form a rigid connection base through the bottom bonding iron plate 3, which can be set inside the voltage transformer housing 10. The bonding iron plate 3 contacts the top surface of the winding 8, ensuring the stability of the overall structure in the horizontal direction, and completing the support and sealing of the epoxy resin filler 9. The support round thread sleeve 2 serves as a vertical positioning element. The adjusting screw 4 connected to its top thread can achieve vertical height adjustment of 0-50 mm, providing a precise vertical positioning reference for the winding 8. The winding 8 is arranged around the iron core 7, so that the top height of the bonding winding 8 is supported. It does not rely on the traditional method of welding to lengthen when it is too short or cutting when it is too long for installation, which increases the assembly adaptability, simplifies operation, and improves assembly efficiency.

[0022] The adjusting screw 4 and the embedded sleeve 5 are integrally formed. The outer wall of the embedded sleeve 5 is provided with anti-slip textures, which are regularly spirally distributed. The depth and spacing of these textures are carefully designed to effectively increase the friction between the embedded sleeve 5 and the palm, preventing slippage during manual length adjustment. Moreover, this integral design and the anti-slip textures simplify the manufacturing process of the adjusting screw and the embedded sleeve 5, reduce assembly steps, lower manufacturing costs, and improve the overall reliability of the support structure.

[0023] The outer wall of the adjusting screw 4 is provided with scale lines. These scale lines are evenly distributed, and each small division represents an adjustment amount of one millimeter. Through the clear and distinct scale markings, the operator can intuitively and accurately grasp the adjustment height of the adjusting screw 4 without the need for additional measuring tools. This further improves the accuracy and convenience of adjustment, ensuring that the vertical positioning of the winding 8 can achieve extremely high precision requirements, meeting the stringent standards for the accuracy of the support structure during the partial discharge treatment of the voltage transformer, and enabling the two symmetrically arranged adjusting screws 4 to perform corresponding height adjustments.

[0024] The bonding iron sheet 3 has an arc shape when viewed from the side. It is welded to one end of the support rod 1. The arc shape of the bonding iron sheet 3 allows for better contact with the outer surface of the voltage transformer, increasing the contact area and providing more stable and reliable support. The welding connection ensures the connection strength between the bonding iron sheet 3 and the support rod 1, enabling it to withstand various external forces during partial discharge treatment of the voltage transformer without loosening or falling off, thus ensuring the stability and safety of the entire support structure. Furthermore, this connection method is technologically mature, easy to operate, and guarantees the consistency and stability of the connection quality.

[0025] See Figure 1 The support rod 1 is perpendicular to the support threaded sleeve 2, and the outer end of the support rod 1 is welded to the bottom end of the support threaded sleeve 2. This vertical and welded connection ensures the stability of the connection between the support rod 1 and the support threaded sleeve 2. During the partial discharge treatment of the voltage transformer, the support structure needs to withstand certain external forces. The vertical welding connection can effectively disperse these external forces and avoid stress concentration at the connection point, thereby ensuring the strength and stability of the entire support structure. At the same time, the welding connection also has the advantages of simple process and low cost, which is conducive to large-scale production and application.

[0026] Please see Figure 1 The adjusting screw 4 is threaded with a locking nut 6 on its outer wall. When the locking nut 6 is rotated to the appropriate position and tightened along the adjusting screw 4, it effectively restricts the axial movement of the adjusting screw 4, preventing it from loosening or displacing due to external forces during the partial discharge treatment of the voltage transformer. This ensures the stability of the relative positions of all components of the support structure. This locking method is simple to operate, requiring only conventional tools such as wrenches to complete the locking and loosening operations. Moreover, the locking effect is reliable and can meet the stringent requirements for the stability of the support structure during the partial discharge treatment of the voltage transformer.
