Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer core technology, specifically a modular assembly dry-type transformer core designed to prevent loosening. Background Technology

[0002] Dry-type transformers are widely used in many fields such as power systems and industrial production. In the assembly process of dry-type transformers, the installation of the core is a crucial step. Traditional dry-type transformer core installation typically uses methods such as bolting or welding, which have several shortcomings. Traditional installation methods are not precise enough in terms of positioning, easily leading to deviations in the core installation position, affecting the overall performance and operational stability of the transformer. Utility Model Content

[0003] The purpose of this invention is to provide a modular assembly dry-type transformer core that prevents loosening, so as to solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is: a modular assembly dry-type transformer core for preventing loosening, comprising multiple core columns and a yoke. Both ends of the core columns and the yoke are provided with assembly inclined surfaces. The assembly inclined surfaces of the core columns are provided with positioning blocks. The assembly inclined surfaces of the yokes are provided with positioning grooves that are adapted to the positioning blocks. Limiting connectors are provided at the corner connections between the core columns and the yokes. Positioning holes for assembling the limiting connectors are opened on the core columns and the yokes.

[0005] The effects achieved by the above components are as follows: the assembly ramps at both ends of the core column and the yoke facilitate preliminary alignment during assembly; the matching structure of the positioning block and positioning groove on the assembly ramps enables precise positioning and reduces installation deviations; the limiting connector at the corner connection between the core column and the yoke, in conjunction with the positioning hole, further fixes the relative position of the core column and the yoke, achieving the purpose of precise core installation and stable connection, reducing the adverse effects of installation position deviations on the overall performance and operational stability of the transformer, and improving the installation quality and operational reliability of the dry-type transformer core.

[0006] Preferably, the limiting connector includes an angle plate that abuts against the inner side of the corner connection between the iron core column and the iron yoke. The angle plate has end plates at both ends that fit against the outer side walls of the iron core column and the iron yoke. The end plates have pin holes, and pins that connect to the positioning holes are provided in the pin holes.

[0007] The effect achieved by the above components is as follows: the corner plate in the limiting connector abuts against the inner side of the corner connection between the core column and the yoke, and the end plate fits against the outer wall of the core column and the yoke. This structural design allows the limiting connector to tightly wrap around the corner of the core column and the yoke, forming a stable constraint on it, effectively preventing the core column and the yoke from loosening or shifting at the corner, thus achieving the purpose of enhancing the stability of the core corner connection, increasing the overall stability of the dry-type transformer core structure, and improving the reliability of the transformer during operation.

[0008] Preferably, a first slot is provided on the inner side of the positioning groove, and a second slot adapted to the first slot is provided on the outer side of the positioning block, with a limit strip sliding between the first slot and the second slot.

[0009] The effect achieved by the above components is that when the limiting strip is slidably inserted between the first slot and the second slot, it can further restrict the relative movement between the positioning block and the positioning groove. Based on the initial positioning of the positioning block and the positioning groove, it achieves the purpose of preventing the positioning block and the positioning groove from loosening and enhancing the stability of the iron core connection part.

[0010] This utility model provides an improved, modularly assembled dry-type transformer core with anti-loosening features, which has the following improvements and advantages compared with the prior art:

[0011] Firstly, this utility model uses the assembly ramps at both ends of the core column and the yoke to facilitate initial alignment during assembly. The matching structure of the positioning block and positioning groove on the assembly ramp enables precise positioning and reduces installation deviation. The limiting connector at the corner of the core column and the yoke works with the positioning hole to further fix the relative position of the core column and the yoke, achieving the purpose of precise installation and stable connection of the core, and reducing the adverse effects of installation position deviation on the overall performance and operational stability of the transformer.

[0012] Secondly, this utility model uses a corner plate in the limiting connector that abuts against the inner side of the corner connection between the core column and the yoke, and an end plate that fits against the outer wall of the core column and the yoke. This structural design allows the limiting connector to tightly wrap around the corner of the core column and the yoke, forming a stable constraint on it. This effectively prevents the core column and the yoke from loosening or shifting at the corner, thereby enhancing the stability of the core corner connection, increasing the overall stability of the dry-type transformer core structure, and improving the reliability of the transformer during operation.

[0018] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0019] This utility model provides an improved, modularly assembled dry-type transformer core designed to prevent loosening. The technical solution of this utility model is as follows:

[0020] In embodiments of this utility model, such as Figures 1-2As shown, a modular assembly dry-type transformer core with anti-loosening features includes multiple core columns 1 and yokes 2. Both ends of the core columns 1 and yokes 2 are provided with assembly ramps. These ramps facilitate initial alignment during assembly. The assembly ramps of the core columns 1 are equipped with positioning blocks 6, and the assembly ramps of the yokes 2 are equipped with positioning grooves 7 that fit the positioning blocks 6. This fit between the positioning blocks 6 and the positioning grooves 7 on the assembly ramps enables precise positioning and reduces installation deviations. A first slot 8 is formed inside the positioning groove 7, and a second slot 9 is formed outside the positioning block 6 that fits the first slot 8. A limiting strip 4 slides between the first slot 8 and the second slot 9. When the limiting strip 4 slides between the first slot 8 and the second slot 9, it further restricts the relative movement between the positioning blocks 6 and the positioning grooves 7. Based on the initial positioning of the positioning blocks 6 and the positioning grooves 7, the core core is then aligned. To prevent loosening between the positioning block 6 and the positioning groove 7 and to enhance the stability of the core connection, a limiting connector 3 is provided at the corner connection between the core column 1 and the yoke 2. The limiting connector 3 includes an angle plate 31 that abuts against the inner side of the corner connection between the core column 1 and the yoke 2. The two ends of the angle plate 31 are provided with end plates 32 that fit against the outer walls of the core column 1 and the yoke 2. The end plates 32 are provided with pin holes 33, and pins 34 that connect to the positioning holes 5 are provided in the pin holes 33. The angle plate 31 in the limiting connector 3 abuts against the inner side of the corner connection between the core column 1 and the yoke 2, and the end plates 32 fit against the outer walls of the core column 1 and the yoke 2. This structural design allows the limiting connector 3 to tightly wrap the corner of the core column 1 and the yoke 2, forming a stable constraint on it and effectively preventing the core column 1 and the yoke 2 from loosening or shifting at the corner. The core column 1 and the yoke 2 are provided with positioning holes 5 for the assembly of the limiting connector 3.

[0021] The working principle of the modular assembly dry-type transformer core provided by this utility model is as follows: The assembly slopes set at both ends of the core column 1 and the yoke 2 make it easier to make initial alignment during assembly. The matching structure of the positioning block 6 and the positioning groove 7 on the assembly slope can achieve precise positioning and reduce installation deviation. When the limiting strip 4 slides between the first slot 8 and the second slot 9, it can further restrict the relative movement between the positioning block 6 and the positioning groove 7. The corner plate 31 in the limiting connector 3 abuts against the inner side of the corner connection between the core column 1 and the yoke 2, and the end plate 32 fits against the outer side of the core column 1 and the yoke 2. This structural design allows the limiting connector 3 to tightly wrap the corner of the core column 1 and the yoke 2, forming a stable constraint on it, effectively preventing the core column 1 and the yoke 2 from loosening or shifting at the corner, and achieving the purpose of precise installation and stable connection of the core.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
