Description

Technical Field

[0001] This utility model relates to the field of transformer shielding window technology, specifically a large transformer riser shielding window that is easy to assemble and disassemble. Background Technology

[0002] Large transformers, as one of the most common electrical equipment, usually require a riser to connect to cables. Since the riser lacks effective protection, a shielding window needs to be installed on the outside of the riser for protection.

[0003] Under current technological conditions, most of the commonly available raised-mounted shielding windows on the market are manufactured using an integrated molding process, which makes the installation and disassembly of the shielding windows complex and cumbersome, and makes it difficult to quickly replace them during later maintenance, causing many inconveniences to operation and maintenance work.

[0004] Therefore, it is necessary to design a shielding window for a large transformer riser that is easy to disassemble and assemble. Utility Model Content

[0005] The purpose of this invention is to provide a shielding window for a large transformer riser that is easy to assemble and disassemble, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a large transformer riser shielding window that is easy to disassemble and assemble, including a transformer, a riser fixedly installed on the upper end of the transformer, a shielding window one placed at the front end of the riser, a shielding window two placed at the rear end of the riser, a fixed platform one set at the middle position on both sides of the shielding window one, a fixed platform two set at the middle position on both sides of the shielding window two, a locking block one fixedly installed at the front end of the fixed platform one, and a locking block two fixedly installed at the front end of the fixed platform two. This simplifies the disassembly and assembly process of the shielding window one and the shielding window two, enables quick disassembly and assembly of the shielding window one and the shielding window two, and saves operation time.

[0007] According to the above technical solution, a support plate is fixedly installed on the upper end of the lifting seat, and a high-pressure sleeve is fixedly installed on the upper end of the support plate.

[0008] According to the above technical solution, locking grooves are symmetrically provided on the upper and lower sides of both locking block one and locking block two.

[0009] According to the above technical solution, an upper fixing rod is fixedly installed in the locking groove on the upper side of the locking block, and a lower fixing rod is fixedly installed in the locking groove on the lower side of the locking block.

[0010] According to the above technical solution, each locking groove has a movable groove at both ends.

[0011] According to the above technical solution, the ends of the upper and lower fixing rods away from the locking block are threaded, and the threaded ends of the upper and lower fixing rods are each fitted with a nut.

[0012] According to the above technical solution, an upper blocking plate is fixedly installed in the moving groove at the upper end of the locking block one and the locking block two.

[0013] According to the above technical solution, a lower blocking plate is fixedly installed in the moving groove at the lower end of the locking block one and the locking block two.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: By providing locking block one and locking block two, this utility model simplifies the disassembly and assembly process of shielding window one and shielding window two, and realizes the rapid disassembly and assembly of shielding window one and shielding window two.

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1-8 The present invention provides a technical solution: a large transformer riser shielding window that is easy to disassemble and assemble, including a transformer 1, a riser 16 fixedly installed on the upper end of the transformer 1, a support plate 3 fixedly installed on the upper end of the riser 16, and a high-voltage sleeve 2 fixedly installed on the upper end of the support plate 3.

[0027] A shielding window 14 is placed at the front end of the lifting seat 16, a shielding window 25 is placed at the rear end of the lifting seat 16, a fixed platform 16 is set at the middle position on both sides of the shielding window 14, and a fixed platform 27 is set at the middle position on both sides of the shielding window 25.

[0028] A locking block 8 is fixedly installed at the front end of fixed platform 1 6, and a locking block 9 is fixedly installed at the front end of fixed platform 2 7.

[0029] Locking slots 15 are symmetrically provided on both the upper and lower sides of locking block 8 and locking block 9.

[0030] An upper fixing rod 13 is fixedly installed in the locking groove 15 on the upper side of the locking block 8, and a lower fixing rod 12 is fixedly installed in the locking groove 15 on the lower side of the locking block 8.

[0031] Each locking groove 15 has a movable groove 17 at both ends.

[0032] The upper fixing rod 13 and the lower fixing rod 12 are threaded at the ends away from the locking block 8, and each threaded end of the upper fixing rod 13 and the lower fixing rod 12 is fitted with a nut 14.

[0033] The upper blocking plate 10 is fixedly installed on the moving groove 17 at the upper end of locking block 8 and locking block 9.

[0034] The lower blocking plate 11 is fixedly installed in the moving groove 17 at the lower end of locking block 8 and locking block 9.

[0035] Working principle:

[0036] During the pre-installation preparation stage, shielding window 4 is placed at the front end of the riser 16, and shielding window 5 is placed at the rear end of the riser 16. The front ends of locking block 8 and locking block 9 are aligned. At this time, the threaded end face of the upper fixing rod 13 is parallel to the upper end face of locking block 8, and the threaded end face of the lower fixing rod 12 is parallel to the lower end face of locking block 8 (e.g., Figure 7 (As shown).

[0037] During the formal installation phase, the upper fixing rod 13 and the lower fixing rod 12 are moved along the groove wall of the locking groove 15 until the shafts of the upper fixing rod 13 and the lower fixing rod 12 are fully embedded in the locking groove 15 (e.g., Figure 8 (As shown), tighten nut 14 until nut 14 is tightly fitted with locking block 2 9, and insert the upper blocking plate 10 and lower blocking plate 11 (as shown) along the moving grooves 17 at the upper and lower ends of locking block 2 9 respectively. Figure 4 As shown), the upper baffle plate 10 and the lower baffle plate 11 prevent fixing failure due to aging and loosening of the nuts. Simply tightening the nut 14 is sufficient to fix the shielding window 1 4 and the shielding window 2 5.

[0038] When it is necessary to disassemble shielding window 4 and shielding window 5, the upper blocking plate 10 and the lower blocking plate 11 are removed along the moving groove 17. The nut 14 is rotated in the opposite direction until it separates from the locking block 9. The upper fixing rod 13 and the lower fixing rod 12 are moved along the groove wall of the locking groove 15 until the shafts of the upper fixing rod 13 and the lower fixing rod 12 disengage from the locking grooves 15 at the upper and lower ends of the locking block 9. At this time, shielding window 4 and shielding window 5 can be disassembled.
