Description

Technical Field

[0001] This utility model relates to the field of converter station installation technology in the power industry, specifically to a protective device for bushing base installation in high-altitude areas. Background Technology

[0002] Converter transformer bushings are typically used in high-voltage power systems, such as ±800kV and ±1100kV. High voltage conditions place extremely high demands on the insulation performance of the bushings; even minor errors during installation can lead to insulation defects and accidents. Therefore, strict control over installation processes and quality is essential. During installation, the installation environment must be carefully controlled to meet specific requirements regarding temperature, humidity, and dust control. Generally, installation should be carried out at temperatures above 5℃ and relative humidity below 75%. If environmental conditions do not meet these requirements, appropriate measures should be taken, such as heating, dehumidification, and air purification.

[0003] The current installation method involves temporarily constructing a relatively enclosed space using simple plastic sheeting when the transformer opening is disassembled. This presents problems such as low air quality at the transformer opening, inadequate emergency measures in rainy weather, and the need for a large number of personnel. These problems are even more pronounced due to the already poor air quality in high-altitude areas. Utility Model Content

[0004] In order to solve the problems in the prior art, this utility model provides a protective device for the installation of sleeve base in high-altitude areas.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A protective device for bushing base installation in high-altitude areas includes an insulated lifting frame, an operating platform at the upper end of the insulated lifting frame, a protective chamber on the operating platform, an opening on the side of the protective chamber near the transformer port, and the other sides being closed by protective plates, forming a sealed space inside the protective chamber that communicates with the transformer port.

[0007] One or more protective panels on one side of the protective room serve as access areas. The protective panels in the access areas are equipped with quick-release mechanisms. These mechanisms have an installed state and a disassembled state. In the installed state, the protective panel on the corresponding side is opened to form an access passage. In the disassembled state, the protective panel on the corresponding side is closed to shut down the access passage.

[0008] The protective room is equipped with air quality and temperature and humidity monitoring equipment.

[0009] Based on the above, the opening side of the protective chamber is the front side, and the rear and upper protective panels of the protective chamber serve as the entry and exit areas;

[0010] The protective chamber is equipped with supporting frames on both the left and right sides, and the left and right protective plates are fixedly connected to the corresponding supporting frames.

[0011] Based on the above, both the rear protective plate and the upper protective plate are composed of two protective sub-plates. Magnetic adhesive is provided at the joint between the protective sub-plate and the supporting frame, as well as at the joint between the two protective sub-plates, thereby forming a quick assembly and disassembly mechanism.

[0012] Based on the above, the rear protective plate, upper protective plate, left protective plate, and right protective plate are transparent acrylic sheets.

[0013] Based on the above, the work platform includes a bottom plane, which serves as the bottom protective plate of the protective chamber.

[0014] Based on the above, the insulated lifting frame includes multiple uprights and cross braces connecting the uprights. The uprights are multi-stage sleeve-type lifting rods and are equipped with lifting locking buckles.

[0015] As described above, a ladder is provided at the rear of the insulated lifting frame.

[0016] Based on the above, the bottom of the insulated lifting frame is equipped with wheels.

[0017] Based on the above, the air quality and temperature / humidity detection mechanism is installed on the left protective plate and / or the right protective plate.

[0018] Based on the above, the air quality and temperature / humidity detection mechanism includes an air quality detector, a temperature / humidity detector, and an air quality early warning device.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model, through the design of a protective chamber, can form a closed, sealed space at the transformer opening, reducing the impact of the external environment, improving the air quality at the transformer opening, and improving emergency measures for rainy weather operations.

[0021] 2. This utility model, through the design of the insulated lifting frame and the quick disassembly and assembly mechanism for the protective room access area, facilitates personnel operation and can be adapted to the operation of transformers of different specifications, thereby improving work efficiency.

[0022] 3. This utility model monitors the temperature, humidity and air quality inside the shed using an air quality detector and a temperature and humidity detector. The detected data is transmitted to an air early warning device for data analysis and status monitoring, and then uploaded to a server for recording. An alarm will be triggered when the air quality indicators do not meet the requirements, thereby improving automation and reducing the number of personnel required for recording.

[0024] Figure 2 This is a side view of the present invention.

[0025] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the present invention. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figures 1 to 2 As shown, this embodiment provides a protective device for bushing base installation in high-altitude areas, including an insulated lifting frame 1. The upper end of the insulated lifting frame 1 is provided with a working platform 2. The working platform 2 is provided with a protective chamber. The side of the protective chamber near the transformer port is opened, and the other sides are closed by protective plates, forming a sealed space inside the protective chamber that communicates with the transformer port.

[0028] With the opening side of the protective chamber as the front side, the rear protective plate 3 and the upper protective plate 4 of the protective chamber serve as the entry and exit area. Support frames 7 are respectively provided on the left and right sides of the protective chamber, and the left and right protective plates 6 are fixedly connected to the corresponding support frames. The work platform 2 includes a bottom plane, which serves as the bottom protective plate of the protective chamber.

[0029] The rear protective plate 3 and the upper protective plate 4 are equipped with quick-release mechanisms. The quick-release mechanisms have an installation state and a disassembly state. In the installation state, the rear protective plate 3 and the upper protective plate 4 are opened to form an access passage. In the disassembly state, the rear protective plate and the upper protective plate are closed to shut down the access passage.

[0030] Specifically, in this embodiment, both the rear protective plate 3 and the upper protective plate 4 are composed of two protective sub-plates. Magnetic adhesive strips 8 are provided at the joints between the protective sub-plates and the supporting frame, as well as at the joints between the two protective sub-plates, thereby forming a quick assembly and disassembly mechanism.

[0031] The two protective panels of the rear protective plate 3 are attached to the rear side of the corresponding support frame by magnetic stickers 8, and the two protective panels are also attached together by magnetic stickers 8.

[0032] The two protective panels of the upper protective plate 4 are attached to the upper side of the corresponding support frame by magnetic stickers 8, and the two protective panels are also attached together by magnetic stickers 8.

[0033] When personnel need to enter or exit, removing the rear protective panel 3 and the upper protective panel 4 will create an access passage. In other cases, the rear protective panel 3 and the upper protective panel 4 are installed normally, and the access passage is closed, serving as a sealed space.

[0034] In this embodiment, the rear protective plate 3, the upper protective plate 4, the left protective plate, and the right protective plate 6 are transparent acrylic plates for easy observation.

[0035] In this embodiment, the insulated lifting frame 1 includes multiple uprights 9 and cross braces 10 connecting the uprights. The uprights 9 are multi-stage sleeve-type lifting rods, which can realize multi-stage height adjustment. After adjustment, they are locked by the lifting locking buckles 11 that cooperate at each stage.

[0036] A ladder 12 is provided at the rear of the insulated lifting frame 1 to facilitate personnel access to the protective room. The bottom of the insulated lifting frame 1 is also equipped with wheels to facilitate the movement of the entire device.

[0037] Inside the protective room, an air quality and temperature / humidity detection mechanism is installed at position 6 on the right side of the protective panel. The air quality and temperature / humidity detection mechanism includes an air quality detector 13, a temperature / humidity detector 14, and an air warning device 15.

[0038] The working principle of this utility model is as follows:

[0039] During use, the insulated lifting frame 1 is adjusted to a suitable height and locked using the lifting locking buckle 11. Personnel climb from the ladder 12 onto the work platform 2, passing through the rear protective plate 3 (if the number of personnel and tools is large or numerous, the upper protective plate 4 is also opened). Afterwards, the rear protective plate 3 and the upper protective plate 4 are closed. During the cleaning and adjustment of the lifting sleeve base hole, the temperature and humidity detector 14 and the air quality detector 13 will operate, monitoring the temperature, humidity, and air quality inside the protective chamber. The data is transmitted to the air quality early warning device 15 for data analysis and status monitoring, and uploaded to the server for recording. An alarm will sound when air quality indicators fail to meet requirements.
