Description

Technical Field

[0001] This utility model relates to the field of high-voltage testing equipment technology, specifically to a convenient high-voltage testing transformer device. Background Technology

[0002] In the inspection and maintenance of power systems and related electrical equipment, high-voltage testing is an indispensable and important part. It is used to test key parameters such as the insulation performance and withstand voltage of electrical equipment. Traditional high-voltage test transformers consist of multiple independent devices, including test control consoles and high-voltage test transformers. These devices are often large and heavy, making them extremely inconvenient to move between different test sites. Therefore, they are all equipped with independent casters for transportation.

[0003] Because the equipment lacks effective protective measures during transportation to the testing site, it is easily damaged by collisions, vibrations, and other factors, affecting the normal operation of the equipment and the accuracy of the testing results. In addition, multiple pieces of equipment are required during the testing process, and multiple people are needed to push the equipment when multiple pieces of equipment are being tested at the same time, which consumes a lot of manpower. Utility Model Content

[0004] The purpose of this invention is to provide a convenient high-voltage test transformer device to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A portable high-voltage test transformer device includes a test control console, a high-voltage test transformer, and a trolley. The test control console and the high-voltage test transformer are both located on the top of the trolley. Two protective railings are fixedly installed on the top of the trolley. A magnetic protective component is provided on the top of the trolley outside the test control console, and a buffer protective component is provided on the top of the trolley outside the high-voltage test transformer. A protective door is rotatably installed inside the front protective railing.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the magnetic protective assembly includes clamps, snap-fit ​​blocks, and magnetic plates. There are four clamps, arranged in pairs, with each pair of clamps fixed to the guardrail by fasteners. There are two snap-fit ​​blocks, each fixed to the front of one pair of clamps. Each snap-fit ​​block has a snap-fit ​​groove inside. The magnetic plate is U-shaped and slides through the two snap-fit ​​grooves. The bottom of the magnetic plate magnetically attracts the top of the trolley, and the test control console is located inside the magnetic plate.

[0008] Furthermore, the buffer protection assembly includes a U-shaped positioning plate, a rotating door, a spring, and a compression plate. The U-shaped positioning plate is fixedly installed on the top of the trolley, the high-voltage test transformer is located inside the U-shaped positioning plate, the spring is fixed to the front and rear sides of the inner wall of the U-shaped positioning plate, and there are two compression plates, which are respectively attached to the front and rear sides of the high-voltage test transformer. The two compression plates are respectively fixed to the front and rear springs.

[0009] Furthermore, there are several springs, which are evenly distributed on the front and rear sides of the inner wall of the U-shaped positioning plate.

[0010] Furthermore, a first EVA buffer cotton is fixedly installed on the left side of the inner wall of the U-shaped positioning plate, and a second EVA buffer cotton is fixedly installed on the left side of the rotating door.

[0011] Compared with the prior art, this utility model provides a convenient high-voltage test transformer device, which has the following beneficial effects: The test control console and high-voltage test transformer are equipped with protective components on the trolley, keeping them within a protected area. This reduces the risk of damage to internal components due to collisions, vibrations, or other factors during transportation. Furthermore, multiple devices can be transported by a single person simply by moving the equipment into the protective components on the trolley and then pushing the trolley for transfer, making the operation quite convenient.

[0014] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0015] Example 1, such as Figures 1-6 As shown, a portable high-voltage test transformer device includes a test control console 1, a high-voltage test transformer 2, and a trolley 3. The test control console 1 and the high-voltage test transformer 2 are both located on the top of the trolley 3. Two protective railings 4 are fixedly installed on the top of the trolley 3. A magnetic protective component 5 is located on the outside of the test control console 1 on the top of the trolley 3. A buffer protective component 6 is located on the outside of the high-voltage test transformer 2 on the top of the trolley 3. A protective door 7 is rotatably installed inside the front protective railing 4. A limiting block that penetrates the bottom of the protective door 7 is snapped into the top of the protective railing 4.

[0016] When transporting the test console 1 and the high-voltage test transformer 2, they are moved to the top of the trolley 3. The magnetic protective assembly 5 and the buffer protective assembly 6 then protect the test console 1 and the high-voltage test transformer 2 respectively, ensuring stability during transport. The limiting blocks (not labeled in the diagram, but can be found from...) Figure 5 As can be seen from the image, the bottom of the protective door 7 can be inserted into the connection between the right side of the protective door 7 and the protective railing 4 (a limiting hole is provided at the connection point, and the opening and closing of the protective door 7 can be restricted by inserting the limiting block).

[0017] Example 2 is a further improvement based on Example 1, and is as follows: The magnetic protective assembly 5 includes a clamp 501, a snap-fit ​​block 502, and a magnetic plate 503. There are four clamps 501, and they are arranged in pairs. Each pair of clamps 501 is fixed to the guardrail 4 by fasteners. There are two snap-fit ​​blocks 502, which are fixed to the front side of each pair of clamps 501. Each snap-fit ​​block 502 has a snap-fit ​​groove 504 inside. The magnetic plate 503 is U-shaped and is slidably installed through the two snap-fit ​​grooves 504. The bottom of the magnetic plate 503 is magnetically attracted to the top of the trolley 3. The test control console 1 is located inside the magnetic plate 503.

[0018] With this setup, the two clamps are secured to the guardrail 4 by fasteners (the fasteners are not shown in the figure, but can be fixed by common bolts and nuts). The clamps with snap-fit ​​blocks 502 are positioned close to the test control console 1, thereby initially guiding the magnetic plate 503 from the left and right sides of the snap-fit ​​slots 504. The bottom of the magnetic plate 503 can magnetically attach to the top of the trolley 3, thus protecting the test control console 1. Furthermore, a rubber pad can be installed inside the magnetic plate 503 to enhance the protection of the test control console 1 and reduce the impact of collisions caused by movement of the test control console 1 inside the magnetic plate 503.

[0019] Example 3 is a further improvement based on Example 1, and its specific details are as follows: The buffer protection component 6 includes a U-shaped positioning plate 601, a rotating door 602, a spring 603, and a compression plate 604. The U-shaped positioning plate 601 is fixedly installed on the top of the trolley 3. The high-voltage test transformer 2 is located inside the U-shaped positioning plate 601. The spring 603 is fixed to the front and rear sides of the inner wall of the U-shaped positioning plate 601. There are two compression plates 604, which are respectively attached to the front and rear sides of the high-voltage test transformer 2. The two compression plates 604 are respectively fixed to the front and rear springs 603.

[0020] With this configuration, the high-voltage test transformer 2 is pushed into the U-shaped positioning plate 601. With the cooperation of the springs 603 on the front and rear sides and the pressing plate 604, the high-voltage test transformer 2 is restricted, and the impact of vibration on the high-voltage test transformer 2 is reduced during the movement of the trolley 3.

[0021] Example 4 is a further improvement based on Example 3. Specifically, there are several springs 603, which are evenly distributed on the front and rear sides of the inner wall of the U-shaped positioning plate 601.

[0022] This configuration, using multiple springs 603, enhances the restraint effect on the high-voltage test transformer 2, thereby further distributing the impact of vibration.

[0023] Example 5 is a further improvement based on Example 3, and it is as follows: A first EVA buffer cotton 8 is fixedly installed on the left side of the inner wall of the U-shaped positioning plate 601, and a second EVA buffer cotton 9 is fixedly installed on the left side of the rotating door 602.

[0024] With this configuration, the first EVA buffer cotton 8 and the second EVA buffer cotton 9 are respectively attached to the front and rear sides of the high-voltage test transformer 2. After the high-voltage test transformer 2 enters the U-shaped positioning plate 601, the cooperation of the first EVA buffer cotton 8 and the second EVA buffer cotton 9 further improves the protection effect on the high-voltage test transformer 2.

[0025] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
