Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer technology, specifically a dry-type transformer with shock absorption function. Background Technology

[0002] Dry-type transformers are transformers whose core and windings are not immersed in insulating oil; they are cooled through methods such as air convection. These transformers are characterized by being flame-retardant, fireproof, explosion-proof, and environmentally friendly. They are safe and reliable to use, and simple and convenient to install and maintain. Therefore, they can be installed near load centers and are widely used in high-rise buildings, subways, railway stations, airports, hospitals, petrochemical plants, and mines.

[0003] However, the existing dry-type transformers have the following drawbacks: the core is composed of multiple core columns, and windings are sleeved on the outside of the corresponding core columns and fixed by upper and lower clamps. Due to the fixing method of this structure, there is no shock absorption device between the core columns and windings and the upper and lower clamps. During long-distance transportation (especially in mountainous areas with poor road conditions), the overall shaking of the dry-type transformer can easily cause the core columns and windings to collide with the upper and lower clamps, thus affecting the normal use of the dry-type transformer. Summary of the Invention

[0004] The purpose of this utility model is to provide a dry-type transformer with shock absorption function to solve the shortcomings of existing dry-type transformers mentioned in the background art: the core is composed of multiple core columns, and windings are sleeved on the outside of the corresponding core columns and fixed by upper and lower clamps. Due to the fixing method of this structure, no shock absorption device is set between the core columns and windings and the upper and lower clamps. During long-distance transportation (especially in mountainous areas with poor road conditions), the overall shaking of the dry-type transformer can easily cause the core columns and windings to collide with the upper and lower clamps, thus affecting the normal use of the dry-type transformer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dry-type transformer with shock absorption function, comprising an iron core, the iron core consisting of multiple core columns and windings surrounding the core columns, an upper clamping assembly fixedly installed on the top of the iron core, a lower clamping assembly fixedly installed on the bottom of the iron core, the upper clamping assembly and the lower clamping assembly respectively clamping the two sides of the core columns, and a shock-absorbing block installed on one end of the upper clamping assembly and the lower clamping assembly near the windings.

[0006] Preferably, the upper clamping assembly includes a first connecting frame and a second connecting frame, which are respectively disposed on both sides of the core column. The first connecting frame and the second connecting frame are connected by fasteners. The upper clamping assembly and the lower clamping assembly adopt the same structural design.

[0007] Preferably, the shock-absorbing block includes a connecting block and a snap-fit ​​block. One end of the connecting block is fixedly connected to the snap-fit ​​block, and the other end of the connecting block has a connecting hole. The connecting hole is fixedly connected to the surface of the first connecting frame and the second connecting frame through a connector.

[0008] Preferably, a heat dissipation cavity is provided inside the winding, and a snap-fit ​​block is snapped into the heat dissipation cavity.

[0009] Preferably, a cavity is formed in the middle of the surface of the snap-fit ​​block.

[0010] Preferably, mounting brackets are fixedly connected to both sides of the bottom of the lower clamp assembly.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figure 1-2 This is a schematic diagram of a preferred embodiment of the present invention of a dry-type transformer with shock absorption function. In this embodiment, a dry-type transformer with shock absorption function includes an iron core 1, which consists of multiple core columns 11 and windings 12 surrounding the core columns 11. An upper clamping assembly 2 is fixedly installed on the top of the iron core 1, and a lower clamping assembly 3 is fixedly installed on the bottom of the iron core 1. The upper clamping assembly 2 and the lower clamping assembly 3 clamp the core columns 11 on both sides respectively. Since the core column 1 is assembled from several chips, the upper clamping assembly 2 and the lower clamping assembly 3 achieve the clamping operation of the core column 11. Furthermore, a shock-absorbing block 4 is installed at one end of the upper clamping assembly 2 and the lower clamping assembly 3 near the windings 12. By installing the shock-absorbing block 4 between the iron core 1 and the upper clamping assembly 2 and the lower clamping assembly 3, and by preventing collisions between the iron core 1 and the upper clamping assembly 2 and the lower clamping assembly 3, the problems mentioned in the background art are effectively solved.

[0023] In this embodiment, the upper clamping assembly 2 includes a first connecting frame 21 and a second connecting frame 22. The first connecting frame 21 and the second connecting frame 22 are respectively disposed on both sides of the core column 11. The first connecting frame 21 and the second connecting frame 22 are connected by fasteners and clamp the core column 11 on both sides. Bolts are used as fasteners to connect the first connecting frame 21 and the second connecting frame 22. The upper clamping assembly 2 and the lower clamping assembly 3 adopt the same structural design.

[0024] In this embodiment, the shock-absorbing block 4 includes a connecting block 41 and a snap-fit ​​block 42. The snap-fit ​​block 42 is fixedly connected to one end of the connecting block 41, and a connecting hole 43 is provided at the other end of the connecting block 41. The connecting hole 43 is fixedly connected to the surface of the first connecting frame 21 and the second connecting frame 22 through a connector.

[0025] In this embodiment, a heat dissipation cavity 13 is provided inside the winding 12, and a snap-fit ​​block 42 is snapped into the heat dissipation cavity 13.

[0026] In this embodiment, a cavity 44 is provided in the middle of the surface of the snap-fit ​​block 42. The opening of the cavity 44 divides the snap-fit ​​block 42 into two small halves. When the snap-fit ​​block 42 is snapped into the heat dissipation cavity 13, the two small halves of the snap-fit ​​block 42 deform into the cavity 44, thereby better fitting with the inner wall of the heat dissipation cavity 13.

[0027] In this embodiment, mounting brackets 5 are fixedly connected to both sides of the bottom of the lower clamp assembly 3, and the installation of the dry-type transformer is achieved through the mounting brackets 5.

[0028] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
