The technical points are: solving the problem that many electrical components are installed inside the existing high-voltage capacitor compensation cabinet, and these electrical components are installed on the mounting bracket inside the cabinet. After the electrical components are installed, the existing bracket is fixed in position and troublesome to disassemble, which is inconvenient for wiring the electrical components. Moreover, it is installed in a deeper position inside the cabinet, which is very inconvenient when it needs to be repaired and replaced.

[0004] However, when the device is used to maintain or repair electrical equipment inside the compensation cabinet, some electrical equipment is placed deeper, and the lines in the compensation cabinet are complicated and not easy to repair and maintain. At this time, maintenance workers are required to lean into the compensation cabinet to perform maintenance tasks. Due to the small maintenance space, workers are prone to being unable to stretch their bodies, making the maintenance process difficult and inconvenient for the progress of maintenance or repair, resulting in reduced work efficiency.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model.

In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0025] See also Figures 1 to 5 The utility model discloses a high-voltage capacitor compensation cabinet with an interlocking device, comprising a cabinet 1. The left side and the right side of the cabinet 1 are provided with heat dissipation ports to prevent the temperature of the electrical equipment inside the cabinet 1 from being too high. The inner wall of the cabinet 1 is fixedly connected with a fixing frame 2. The cabinet 1 limits the position of the fixing frame 2. At the same time, the fixing frame 2 provides a supporting force for the cabinet 1, so that the cabinet 1 will not be deformed in a large range when it is hit by an external force to damage the electrical equipment inside the cabinet 1. The inner bottom wall of the fixing frame 2 is provided with two sliding grooves 3. The interior of the fixing frame 2 is provided with two limiting grooves 4. The inner wall of each sliding groove 3 is slidably connected with a sliding block 5. The sliding groove 3 provides a movable space for the sliding block 5 and limits the movement trajectory of the sliding block 5 to improve the movement stability. The inner wall of each limit groove 4 is slidably connected to the limit block 6. The limit groove 4 limits the movement space of the limit block 6, so that the limit block 6 can move stably to prevent deviation. The outer surface of each sliding block 5 contacts the outer surface of the corresponding limit block 6. Specifically, each limit groove 4 is distributed on the left and right sides of the corresponding sliding groove 3, and is the same as the corresponding sliding groove 3, so that the limit block 6 can enter the corresponding sliding groove 3 to achieve the effect of limiting the sliding block 5.

[0026] In this embodiment, two movable grooves 8 are provided on the front of the fixed frame 2, and the movable grooves 8 are located directly in front of the corresponding movable grooves 8 and are connected to the corresponding limit grooves 4. The side faces of each limit block 6 that are away from each other are fixedly connected with a spring 7, and the ends of each spring 7 that are away from each other are fixedly connected with the inner wall of the limit groove 4. The spring 7 is the power source required for the movement of the limit block 6, and the limit block 6 is pushed by the sliding block 5. The limit block 6 compresses the spring 7 to store potential energy, and the limit block 6 is reset by the rebound of the spring 7, thereby achieving the effect of locking the position of the sliding block 5. A pull rod 9 is fixedly connected to the front of each limit block 6, and the outer surface of each pull rod 9 is slidably connected to the inner wall of the corresponding movable groove 8. When the sliding block 5 needs to leave the sliding groove 3, the limit block 6 is driven to move by moving the pull rod 9, thereby unlocking the position of the sliding block 5.

[0027] In this embodiment, the front side of the fixed frame 2 is rotatably connected to two locking members 10. By rotating the locking member 10, the notch of the locking member 10 is brought into contact with the corresponding pull rod 9, so that the locking member 10 locks the position of the pull rod 9 to facilitate the sliding block 5 to leave the sliding groove 3. The inner wall of the fixed frame 2 is fixedly connected to two fixing plates 11, which are located above the sliding groove 3 and distributed on both sides of the fixed frame 2. A supporting frame 12 is provided inside the cabinet 1, and the outer surface of the supporting frame 12 is in sliding contact with the inner wall of the fixed frame 2, and the fixed frame 2 provides support force for the supporting frame 12.

[0028] In a preferred embodiment, two positioning plates 13 and two positioning blocks 14 are fixedly connected to the inner wall of the carrier 12, and the bottom surface of each positioning plate 13 is fixedly connected to the upper surface of the corresponding sliding block 5. The positioning plate 13 is connected to the sliding block 5, so that the carrier 12 can move synchronously with the sliding block 5, so that the position of the carrier 12 can be locked with the inside of the cabinet 1 synchronously with the sliding block 5 to prevent the carrier 12 from moving around. The outer surface of each positioning block 14 is slidably connected to the inner wall of the corresponding fixed plate 11, and the positioning block 14 is connected to the fixed plate 11, so that the carrier 12 can maintain balance and stability when entering or leaving the cabinet 1.

[0029] In this embodiment, the internal rotation of the carrier 12 is connected to two knobs 15, and the outer surface of each knob 15 is fixedly connected to a bevel gear 16. The knob 15 limits the position of the bevel gear 16 so that the bevel gear 16 can rotate synchronously with the knob 15. The outer surface of each bevel gear 16 is meshed with a bevel gear 2 17. Specifically, the bevel gear 16 is driven to rotate by the knob 15, and the bevel gear 16 is meshed with the corresponding bevel gear 2 17, so that the bevel gear 2 17 rotates synchronously.

[0030] In a preferred embodiment, two movable cavities 18 are opened inside the carrier 12, and the movable cavities 18 are respectively located below the corresponding bevel gear 2 17. The inner bottom wall of each movable cavity 18 is rotatably connected with a threaded rod 19. The movable cavity 18 provides the required space for the threaded rod 19 and limits the position of the threaded rod 19. The top end of each threaded rod 19 is fixedly connected to the bottom surface of the corresponding bevel gear 2 17, and the corresponding threaded rod 19 is driven to rotate through the bevel gear 2 17.

[0031] In this embodiment, the outer surface of each threaded rod 19 is threadedly connected with a moving block 20. The threaded rod 19 is rotated forward or reversely, and the threaded rod 19 drives the moving block 20 to achieve the effect of rising or falling. Each moving block 20 is slidably connected to the inner wall of the corresponding active cavity 18. The active cavity 18 limits the movement trajectory of the moving block 20, so that the movement of the moving block 20 is more stable. The outer surface of each moving block 20 is fixedly connected with a supporting leg 21, and the interior of each supporting leg 21 is rotatably connected with a foot plate 22. Specifically, the moving block 20 is driven to rise or fall by the threaded rod 19, and the moving block 20 drives the corresponding supporting leg 21 to move synchronously. When the supporting leg 21 is about to contact the ground, the foot plate 22 is rotated parallel to the ground, so that the contact area of ​​the supporting leg 21 with the ground is increased, thereby increasing stability.

[0032] In a preferred embodiment, hinges 23 arranged at equal distances are fixedly connected to the outer surface of the cabinet body 1, and a cabinet door 24 is in contact with the front of the cabinet body 1. The outer surface of each hinge 23 is fixedly connected to the outer surface of the cabinet door 24. The cabinet body 1 and the cabinet door 24 are connected by the hinges 23, so that the electrical equipment is enclosed, which can effectively prevent people other than maintenance personnel from contacting the electrical equipment, thereby increasing safety.
