Description

Technical Field

[0001] The present invention relates to the field of financial payment, and in particular to an impact-resistant housing structure for a dry-type transformer. Background Art

[0002] A dry-type transformer refers to a transformer structure that is not immersed in insulating oil. Such transformers are used in various low-power usage scenarios due to their relatively small structure and light weight, and their maintenance costs are also lower. However, since dry-type transformers do not have a housing like wet-type transformers during use and transportation, they are prone to collisions, which can cause damage to the dry-type transformer. Some also cover an outer shell on the outside of the dry-type transformer, but the dry-type transformer after adding the housing has an increased volume and weight, which is also not conducive to maintenance and repair. To solve the above problems, an impact-resistant housing structure for a dry-type transformer is specially designed. Summary of the Invention

[0003] The purpose of the present invention is to provide an impact-resistant housing structure for a dry-type transformer to solve the above technical problems. To achieve the above purpose, the present invention adopts the following technical solutions:

[0004] An impact-resistant housing structure for a dry-type transformer includes a dry-type transformer body and a single-body protection housing assembly. There are several groups of the single-body protection housing assemblies, and several groups of the single-body protection housing assemblies are arranged in parallel. End-side fixing guard plates are arranged on the upper and lower sides of the dry-type transformer body. Shell fixing holes are opened at the edges of the end-side fixing guard plates. The several groups of the single-body protection housing assemblies are arranged on the side of the dry-type transformer body, and the upper and lower ends of the several groups of the single-body protection housing assemblies are respectively fixed to the shell fixing holes on the end-side fixing guard plates by bolts.

[0005] On the basis of the above technical solution, the single-body protection housing assembly is composed of side end plates, strip plates, buffer plate members, and side vertical fixing plates. There are multiple groups of the strip plates, and multiple groups of the strip plates are arranged in parallel. There are two groups of the side end plates, and the two groups of the side end plates are symmetrically arranged at both ends of the multiple groups of the strip plates. There are several groups of the buffer plate members, and the several groups of the buffer plate members are arranged at equal intervals on the strip plates, and the buffer plate members on adjacent strip plates are arranged alternately. There are two groups of the side vertical fixing plates, and the two groups of the side vertical fixing plates are respectively arranged on the rear side ends of the two groups of the side end plates. The side end plates, strip plates, buffer plate members, and side vertical fixing plates are integrally welded. A shell fixing hole is opened at the center of the side vertical fixing plate, and the shell fixing hole on the side vertical fixing plate corresponds to the shell fixing hole on the end-side fixing guard plate.

[0006] Based on the above technical solution, the buffer plate member is composed of an arc-shaped buffer plate and an inner triangular folding plate. The inner triangular folding plate is arranged inside the arc-shaped buffer plate, and the two end corners of the inner triangular folding plate are arranged at the same position as the rear end of the arc-shaped buffer plate. The arc-shaped buffer plate is integrally stamped with the strip plate, and the inner triangular folding plate is welded to the side end of the strip plate and the inner side of the arc-shaped buffer plate.

[0007] Compared with the prior art, the present invention has the following advantages: The present invention optimizes the structural design of the dry-type transformer housing, changes the traditional integral protective housing of the dry-type transformer, and improves it into a single-piece assembled protective housing. The housing has the ability to resist impact and buffer the impact force. Moreover, the single-piece design is more conducive to replacement and installation, with lower use and maintenance costs, and does not affect the structural heat dissipation effect of the dry-type transformer, so it is suitable for popularization and use.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention will be further elaborated in detail below in conjunction with the drawings and specific embodiments.

[0014] An impact-resistant housing structure for a dry-type transformer includes a dry-type transformer body 1 and a single-piece protective housing assembly 2. A plurality of groups of single-piece protective housing assemblies 2 are provided and arranged in parallel. End-side fixed guard plates 3 are provided on the upper and lower sides of the dry-type transformer body 1. Housing fixed hole positions 4 are opened at the edges of the end-side fixed guard plates 3. The plurality of groups of single-piece protective housing assemblies 2 are arranged on the side of the dry-type transformer body 1, and the upper and lower ends of the plurality of groups of single-piece protective housing assemblies 2 are respectively fixed to the housing fixed hole positions 4 on the end-side fixed guard plates 3 by bolts.

[0015] The single-body protective housing assembly 2 is composed of side end plates 5, strip plates 6, buffer plate members 7, and side vertical fixing plates 8. There are multiple groups of the strip plates 6, and the multiple groups of strip plates 6 are arranged in parallel. There are two groups of the side end plates 5, and the two groups of side end plates 5 are symmetrically arranged at both ends of the multiple groups of strip plates 6. There are several groups of the buffer plate members 7, and the several groups of buffer plate members 7 are arranged at equal intervals on the strip plates 6, and the buffer plate members 7 on adjacent strip plates 6 are arranged alternately. There are two groups of the side vertical fixing plates 8, and the two groups of side vertical fixing plates 8 are respectively arranged at the side ends of the rear sides of the two groups of side end plates 5. The side end plates 5, strip plates 6, buffer plate members 7, and side vertical fixing plates 8 are integrally welded. A housing fixing hole position 4 is opened at the center of the side vertical fixing plate 8, and the housing fixing hole position 4 on the side vertical fixing plate 8 corresponds to the housing fixing hole position 4 on the end-side fixing guard plate 3.

[0016] The buffer plate member 7 is composed of an arc-shaped buffer plate 9 and an inner triangular folding plate 10. The inner triangular folding plate 10 is arranged inside the arc-shaped buffer plate 9, and the two side end corners of the inner triangular folding plate 10 are arranged at the same position as the rear side end of the arc-shaped buffer plate 9. The arc-shaped buffer plate 9 and the strip plate 6 are integrally stamped. The inner triangular folding plate 10 is welded to the side end of the strip plate 6 and the inside of the arc-shaped buffer plate 9.

[0017] The working principle of the present invention: The use principle of this structure is simple, mainly reflected in the safety effect during handling and use, reducing the damage to the dry-type transformer body 1. The buffer plate member 7 designed in the structure has an arc-shaped buffer plate 9, which can weaken the impact and collision of external forces on the transformer body. The inner triangular folding plate 10 can provide strong support during the buffering process to prevent the arc-shaped buffer plate 9 from being overly deformed and colliding with the dry-type transformer body 1. The single-body protective housing structure 2 provided can be disassembled and installed in single groups because it is set in single groups. During maintenance, it is more convenient to disassemble compared to an integrated housing. During the handling process, its mass is relatively light. And when the single-body protective housing structure 2 is accidentally damaged, only one group of the single-body protective housing structure 2 needs to be replaced during replacement, and the maintenance cost is lower.

[0018] The above is the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, the changes, modifications, substitutions, and variations made to the embodiments still fall within the protection scope of the present invention.
