Description

Technical Field

[0001] This utility model relates to the technical field of electrical engineering, specifically to a high-voltage switchgear cable tray structure. Background Technology

[0002] High-voltage switchgear is a key electrical device in power systems used for power distribution, control, and protection. It integrates components such as circuit breakers, disconnectors, transformers, and surge arresters to control the on / off state of power lines, provide fault protection, and monitor operation. The switchgear contains various cables, including power cables, control cables, and communication cables. Cable trays provide independent channels for these cables, preventing tangling and ensuring a clear and easily identifiable layout. Top cable trays are a common type of high-voltage switchgear cable tray. Existing technology features a base plate fixed to the top of the switchgear, supporting the cable tray. Multiple branch trays are located on the base plate, allowing cables to enter from one end and exit from the other, separating the cables and maintaining a certain level of neatness. However, the above-mentioned common high-voltage switchgear cable tray structure still has shortcomings:

[0003] During the wiring process, the wires usually need to be passed through the entire cable tray. Due to insufficient space at the top of the high-voltage cabinet, the wiring process is time-consuming and laborious. Furthermore, the edges of the cable tray are prone to damaging the surface of the wires, and traditional cable trays are not very effective at securing cables. Utility Model Content

[0004] The purpose of this utility model is to provide a high-voltage switchgear cable tray structure to solve the problems mentioned in the background art, which are that during the cable laying process, it is usually necessary to pass the wires through the entire cable tray. Due to insufficient space at the top of the high-voltage switchgear, the wires are difficult to pass through, and the edges of the cable tray are prone to damaging the surface of the wires. In addition, traditional cable trays have poor fixing effect on the wires and cables.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage switchgear cable tray structure, including a cable tray box, a sliding cavity at the bottom of the cable tray box, multiple cable tray assemblies inside the cable tray box, multiple cable guide grooves inside the sliding cavity, cable guide assemblies slidably connected inside the multiple cable guide grooves, a limit assembly on one side of the connection between the multiple cable guide grooves and the sliding cavity, and a cable fixing assembly threadedly connected to one end of the top of the multiple cable tray assemblies.

[0006] Preferably, the junction box assembly includes a junction box, which is disposed on a cable tray box. One end of the inner wall of the junction box is fixedly connected to a cable guide, and one end of the top of the junction box is provided with a threaded sleeve, which facilitates the separation of various cable lines and protects the lines.

[0007] Preferably, the wire fixing assembly includes a first fixing screw, one end of which is rotatably connected to a first support plate, and one side of the first support plate is provided with a first rubber layer, which is beneficial for fixing one end of the wire.

[0008] Preferably, the lead wire assembly includes a lead wire slider, which is disposed inside the lead wire groove. One end of the lead wire slider is fixedly connected to a lead wire box, and the other end of the lead wire slider has a limit slot, which greatly improves the cable laying efficiency and makes the operation simple, time-saving and labor-saving.

[0009] Preferably, the middle of the lead wire slider is threadedly connected to a second fixing screw, one end of the second fixing screw is rotatably connected to a second support plate, one side of the second support plate is provided with a second rubber layer, and the surface of the second support plate is slidably connected to the inner wall of the lead wire box.

[0010] Preferably, the limiting component includes a perforated support plate connected within a sliding cavity. A limiting slide rod is slidably connected inside the perforated support plate. A return spring is fixedly connected between the limiting slide rod and the perforated support plate. A rotating seat is fixedly connected to one end of the limiting slide rod. A rotating rod limiting plate is rotatably connected inside the rotating seat. The rotating rod limiting plate engages with a limiting slot, which facilitates limiting the lead wire assembly and ensures the stability of the fixed line.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the cable guide assembly facilitates cable threading, and a cable guide slide is provided at one end of the cable inlet. The cable guide slide is a smooth channel, which helps to prevent damage to the cable sheath during the cable threading process. After the cable is threaded into one end of the junction box, the second fixing screw is rotated to make the second support plate press against the cable. Then, the cable guide slider is moved to guide one end of the cable to the other end, thus completing the cable threading process. The cable guide assembly can greatly improve the cable threading efficiency, and the operation is simple, time-saving and labor-saving. The cable guide assembly is fixed by the limiting component, at which point one end of the cable is fixed. Then, the other end of the cable is fixed by the cable fixing component. At this time, both ends of the cable are firmly fixed, which helps to stabilize the electrical connection and prevent accidental pulling. Attached Figure Description

[0018] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-5 This utility model provides a high-voltage switchgear cable tray structure, including a cable tray box 1. The bottom of the cable tray box 1 is provided with a sliding cavity 2. Multiple cable box assemblies are arranged inside the cable tray box 1. Multiple cable guide grooves 9 are provided inside the sliding cavity 2. Cable guide assemblies are slidably connected inside the multiple cable guide grooves 9. Limiting components are provided on one side of the connection between the multiple cable guide grooves 9 and the sliding cavity 2. Cable fixing components are threadedly connected to one end of the top of the multiple cable box assemblies.

[0020] See Figure 1 and Figure 2 Furthermore, the junction box assembly includes a junction box 3, which is disposed on the cable tray box 1. One end of the inner wall of the junction box 3 is fixedly connected to a cable routing slide 8, and one end of the top of the junction box 3 is provided with a threaded sleeve 4. The cable fixing assembly includes a first fixing screw 5, one end of the first fixing screw 5 is rotatably connected to a first support plate 6, and one side of the first support plate 6 is provided with a first rubber layer 7.

[0021] During use, as the cable passes through the junction box 3, the cable slides on the cable guide 8, providing a smooth path for the moving cable and helping to prevent damage to the cable sheath during the cable threading process. When the cable layout is complete, the first fixing screw 5 is rotated. The first fixing screw 5 is threaded into the inside of the threaded sleeve 4, and the surface of the first support plate 6 is slidably connected to the inner wall of the junction box 3. Therefore, the first fixing screw 5 moves downward, driving the first support plate 6 to move until the first rubber layer 7 presses against the surface of the cable, fixing it in place.

[0022] See Figure 3 , Figure 4 and Figure 5Furthermore, the headband assembly includes a headband slider 10, which is disposed inside the headband groove 9. One end of the headband slider 10 is fixedly connected to a headband box 11, and the other end of the headband slider 10 is provided with a limiting slot 15. The middle of the headband slider 10 is threadedly connected to a second fixing screw 12, and one end of the second fixing screw 12 is rotatably connected to a second support plate 13. A second rubber layer 14 is provided on one side of the second support plate 13, and the surface of the second support plate 13 is slidably connected to the inner wall of the headband box 11. The limiting assembly includes a perforated support plate 16, which is connected to the sliding cavity 2. A limiting slide rod 17 is slidably connected inside the perforated support plate 16. A return spring 18 is fixedly connected between the limiting slide rod 17 and the perforated support plate 16. One end of the limiting slide rod 17 is fixedly connected to a rotating seat 19, and a rotating rod limiting plate 20 is rotatably connected inside the rotating seat 19. The rotating rod limiting plate 20 is engaged with the limiting slot 15.

[0023] In use, after inserting the cable into the junction box 3, one end of the cable passes through the cable tray 11. Then, rotate the second fixing screw 12 to move it upward. At this time, the second support plate 13 moves upward until the second rubber layer 14 abuts against the surface of the cable, fixing the cable end. Moving the cable tray slider 10 can then move the cable tray 11. When the cable tray 11 moves to the other end, the cable end can protrude from the junction box 3. At this point, we can rotate the second fixing screw 12 in the opposite direction to allow the cable to... It can move freely, which is beneficial for subsequent wiring work. After the wiring is completed, the cable can be limited by rotating the second fixing screw 12. Then, pull the limiting slide bar 17. At this time, the return spring 18 is in a stretched state. Rotate the rotating rod limiting plate 20 to align it with the limiting slot 15. Then release the limiting slide bar 17. Under the action of the return spring 18, the rotating rod limiting plate 20 is pressed tightly against the inside of the limiting slot 15, which can press the cable guide slider 10 tightly against the inner wall of the sliding cavity 2. At this time, the cable at this end is firmly fixed.

[0024] In this embodiment, the following steps are taken: First, the cable tray 1 is fixed to the top of the high-voltage cabinet through the fixing holes on the cable tray 1. Then, the cable guide assembly is moved to the position of the cable laying slide 8. One end of the cable is inserted into the inside of the junction box 3, and the other end of the cable is passed through the cable guide box 11. At this time, rotating the second fixing screw 12 fixes the cable. The operator can then directly move the cable guide slider 10 to pass one end of the cable through the junction box 3. When the cable guide slider 10 moves the cable guide box 11 to the other end of the junction box 3, the end of the cable protrudes from the inside of the junction box 3. At this point, the operator rotates the second fixing screw 12 to continue laying the cable. After the wiring is completed, we need to fix the cables inside the junction box 3. We rotate the first fixing screw 5 to fix the cable at the inlet end. Then, we move the cable guide slider 10 to the end position, close to the limit component, and rotate the second fixing screw 12 to fix the other point of the cable. Then, the limit component tightly presses the cable guide component to ensure the stability of the cable at this end. The rubber layer in contact with the circuit surface can play an anti-slip role and make the limiting effect better. The rotating rod limit plate 20 can rotate inside the rotating seat 19 to prevent the rotating rod limit plate 20 from interfering with the movement of the cable guide slider 10.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
