[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] Please refer to Figure 1-4 A new type of arc-extinguishing PT cabinet includes a PT cabinet body 1, a vertical structure, and a horizontal member 3. The vertical structure and the horizontal member 3 together constitute an outer frame as a whole. A groove 4 is provided on the upper surface of the horizontal member 3. A slider 10 is movably installed on the inner wall of the groove 4. A support plate 6 is fixedly installed on the upper surface of the slider 10. A first through hole 7 is provided on the upper surface of the support plate 6. A limit frame 8 is fixedly installed on the upper surface of the horizontal member 3. Sliders 10 are fixedly installed on the left and right surfaces of the support plate 6. A limit hole 9 is provided on the upper surface of the limit frame 8. A second through hole 11 is provided on the upper surface of the slider 10. A mounting plate 12 is fixedly installed on the upper surface of the support plate 6. A movable column 13 is movably installed in the middle of the mounting plate 12. A pull plate 14 is fixedly installed on the upper surface of the movable column 13. A spring 15 is fixedly installed on the upper inner wall of the mounting plate 12. A limit block is fixedly installed on the lower end of the movable column 13.

[0023] Specifically: During the use of the present invention, when it is necessary to inspect and repair a part of the PT cabinet body 1, the pull plate 14 is manually pulled upward, and the pull plate 14 moves upward. At this time, the spring 15 is in a contracted state, thereby driving the movable column 13 to move upward, and the movable column 13 moves upward, thereby driving the limit block to move upward. In the process of moving upward, the limit block gradually moves away from the surface of the limit hole 9 and the second through hole 11 until the limit block is completely away from the second through hole 11 and the inside of the limit hole 9. At this time, the support plate 6 can be moved. After the support plate 6 is moved to the required position as needed, the pull plate 14 is slowly released, and the tension disappears. The spring 15 drives the limit block to move toward the inside of the second through hole 11 and the limit hole 9 due to its own resilience. Until the limit block completely enters the inside of the limit hole 9, it can be limited. At this time, the support plate 6 is in an exposed state. When the inspection is completed, the support plate 6 can be directly re-inserted into the inside of the outer frame according to the same principle.

[0024] In this embodiment, a movable door 18 is hingedly connected to the front surface of the PT cabinet body 1 , a handle 19 is fixedly mounted on the front surface of the movable door 18 , and a universal wheel 20 is fixedly mounted on the lower surface of the vertical member 2 .

[0025] Specifically, when the outer frame needs to be moved as a whole, it is sufficient to drag the outer frame as a whole out. The universal wheels 20 are used to facilitate dragging the outer frame as a whole.

[0026] In this embodiment: the outer surface of the slider 10 is movably connected to the inner wall of the limit frame 8, the sizes of the limit hole 9, the second through hole 11 and the limit block match each other, and the lower end of the spring 15 is fixedly connected to the upper surface of the limit block.

[0027] Specifically, the spring 15 is used to limit the limiting block so that it is located inside the limiting hole 9 .

[0028] Working principle: This design drives the movable column 13 to move by pulling the pull plate 14, and the movable column 13 drives the limit block to move, thereby realizing the movement of the support plate 6. The limit block is limited by the resilience of the spring 15, thereby achieving the effect of limit fixation. Compared with the related technology, the new arc-extinguishing PT cabinet provided by the utility model has the following beneficial effects: This design realizes the effect of local extraction and detection of the PT cabinet body 1, which is convenient for maintenance personnel to carry out precise processing, saves time and improves efficiency.

[0029] Example 2:

[0030] Please refer to Figure 1-4A control switch 16 is fixedly mounted on the front surface of the PT cabinet body 1 , and a light strip 17 is fixedly mounted on the inner wall and upper surface of the PT cabinet body 1 .

[0031] Specifically, when the user opens the movable door 18, the control switch 16 loses the pressure exerted by the movable door 18, and the control switch 16 turns on. The control switch 16 turns on, thereby driving the light strip 17 to turn on, thereby illuminating the interior of the PT cabinet body 1. When the movable door 18 is closed, the movable door 18 presses the control switch 16, and the control switch 16 turns off, thereby driving the light strip 17 to turn off.

[0032] In this embodiment, the control switch 16 is electrically connected to the light strip 17 .

[0033] Specifically, the control switch 16 controls the light strip 17 to be turned on and off.

[0034] Working principle: This design opens and closes the control switch 16 by opening and closing the movable door 18, thereby opening and closing the light strip 17. Compared with related technologies, the new arc-extinguishing PT cabinet provided by the utility model has the following beneficial effects: This design can illuminate the interior of the PT cabinet body 1, making it convenient for workers to observe the interior of the PT cabinet body 1 in some darker environments, thereby increasing its scope of application and saving resources.

[0035] The above-mentioned equipment is used in different ways for each device. It should be selected and used according to actual conditions, and various parameters should be referred to, in accordance with the functions of the equipment used and the effects achieved.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
