[0024] The positioning bolt 9 is movably connected to the positioning groove 6, and the mounting plate 7 is movably connected to the mounting frame 3;

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, during installation, each group of electrical equipment is installed inside the mounting box 2. Then, the mounting box 2 is inserted into the cabinet 1 so that the mounting plate 7 is attached to one end of the mounting frame 3. The positioning bolt 9 is pulled to one side so that the positioning nut 24 is inserted between the corresponding fixing pieces 16. The fixing pieces 16 can position the positioning nut 24 to prevent the positioning nut 24 from rotating. Finally, the positioning bolt 9 is rotated to tighten it, so that the positioning bolt 9 and the positioning nut 24 are attached to both ends of the mounting frame 3 to support and position the mounting box 2. The multiple groups of equipment inside the mounting box 2 are monitored in a comprehensive and real-time manner through technologies such as partial discharge monitoring, online mechanical characteristic monitoring, online SF6 gas density monitoring, and remote transmission monitoring terminal of digital meter of surge arrester, so as to realize multi-point joint analysis and realize the rapid installation of multiple groups of equipment.

[0026] Fixed sleeves 15 are fixedly connected to the four corners inside the cabinet 1. One end of the fixed sleeve 15 is provided with a through hole 20. Movable rods 19 are fixedly connected to the four corners at one end of the mounting frame 3. The movable rods 19 pass through the through hole 20 and extend into the inside of the fixed sleeve 15. Anti-detachment plates 22 are fixedly connected to the inside of the anti-detachment plates 22. Grooves 23 are provided at both ends of the anti-detachment plates 22.

[0028] The through hole 20 is movably connected to the fixed sleeve 15, and the center line of the movable rod 19 and the center line of the fixed sleeve 15 are on the same vertical plane;

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when it is necessary to inspect or repair the internal electrical equipment or to connect or route cables, the mounting frame 3 can be pulled to move the movable rod 19 to one end. The movable rod 19 moves the anti-detachment plate 22 to support the mounting frame 3. After the mounting frame 3 moves the mounting box 2 out of the cabinet 1, it is convenient to inspect and repair the equipment inside the mounting box 2, thus realizing the convenience of wiring and repairing multiple sets of equipment.

[0030] One end of the screen cabinet 1 is fixedly connected to an air chamber 14. The top of the screen cabinet 1 is provided with an air inlet 4.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, when the device is running, the cooling fan 13 inside the mounting slot 11 is activated. After the cooling fan 13 is activated, it can accelerate the air circulation inside the cabinet 1, thereby quickly dissipating the heat generated inside the cabinet 1 during operation. The air inlet 4 at the top can provide an air intake channel, and the dustproof net 5 inside the air inlet 4 can prevent dust from entering. The air guide chamber 14 at one end of the cabinet 1 can expand the ventilation channel, thus achieving effective heat dissipation during operation.

[0033] Working Principle: In use, each group of electrical equipment is installed inside the mounting box 2. Then, the mounting box 2 is inserted into the cabinet 1, so that the mounting plate 7 fits against one end of the mounting frame 3. Pulling the positioning bolt 9 to one side causes the positioning nut 24 to insert between the corresponding fixing plates 16. The fixing plates 16 position the positioning nut 24, preventing it from rotating. Finally, the positioning bolt 9 is rotated to tighten it, so that the positioning bolt 9 and the positioning nut 24 fit against both ends of the mounting frame 3, supporting and positioning the mounting box 2. Multiple groups of equipment inside the mounting box 2 undergo comprehensive and real-time monitoring of the GIS equipment's operating conditions using technologies such as partial discharge monitoring, online mechanical characteristic monitoring, online SF6 gas density monitoring, and remote monitoring terminals for digital meters of surge arresters. To achieve multi-point joint analysis, when it is necessary to inspect or connect internal electrical equipment, the mounting frame 3 can be pulled to move the movable rod 19 to one end. The movable rod 19 moves the anti-detachment plate 22 to support the mounting frame 3. After the mounting frame 3 moves the mounting box 2 out of the cabinet 1, it is convenient to inspect and connect the equipment inside the mounting box 2. When the equipment is running, the cooling fan 13 inside the mounting slot 11 is activated. After the cooling fan 13 is activated, it can accelerate the air circulation inside the cabinet 1, thereby quickly dissipating the heat generated inside the cabinet 1 during operation. The air inlet 4 at the top can provide an air intake channel, and the dustproof net 5 inside the air inlet 4 can prevent dust from entering. The air guide chamber 14 at one end of the cabinet 1 can expand the ventilation channel.

[0034] Compared with the prior art, the beneficial effects of this utility model include: the quick-installable GIS partial discharge monitoring device not only enables the rapid installation of multiple sets of equipment and facilitates wiring and maintenance, but also achieves effective heat dissipation.

[0035] Specifically, the system is equipped with a mounting box, mounting frame, positioning slot, mounting plate, mounting holes, positioning bolts, fixing plates, and positioning nuts. During installation, each group of electrical equipment is installed inside the mounting box. Then, the mounting box is inserted into the cabinet so that the mounting plate fits against one end of the mounting frame. Pulling the positioning bolt to one side causes the positioning nut to be inserted between the fixing plates in the corresponding positions. The fixing plates can position the positioning nut to prevent it from rotating. Finally, the positioning bolt is rotated to tighten it, so that the positioning bolt and the positioning nut fit against both ends of the mounting frame to support and position the mounting box. The multiple groups of equipment inside the mounting box are monitored in a comprehensive and real-time manner using technologies such as partial discharge monitoring, online mechanical characteristic monitoring, online SF6 gas density monitoring, and remote monitoring terminal for digital meters of surge arresters. This enables multi-point joint analysis and allows for the rapid installation of multiple groups of equipment.

[0036] With a mounting frame, fixed sleeve, movable rod, through hole, ball bearing, anti-detachment plate, and groove, when it is necessary to inspect or repair the internal electrical equipment or to connect or route cables, the mounting frame can be pulled to move the movable rod to one end. The movable rod moves the anti-detachment plate to support the mounting frame. After the mounting frame moves the mounting box out of the cabinet, it is convenient to inspect and repair the equipment inside the mounting box and connect cables. This allows for convenient wiring, cable routing, and inspection of multiple sets of equipment.

[0037] Equipped with an air inlet, dust filter, mounting slot, air outlet, cooling fan, and air duct, the device activates the cooling fan inside the mounting slot during operation. This accelerates airflow within the cabinet, quickly dissipating the heat generated during operation. The top air inlet provides an air intake channel, and the dust filter inside prevents dust from entering. The air duct at one end of the cabinet expands the ventilation path, enabling effective heat dissipation during operation.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
