Description
Technical Field
[0001] This utility model belongs to the technical field of 110kV line cable terminal installation, specifically relating to a component device for non-magnetic installation of 110kV line cable terminals. Background Technology
[0002] 110kV lines are an important high-voltage transmission level in the power system, responsible for the transmission and distribution of electrical energy between regional power grids. They typically use steel-cored aluminum stranded wire, with the steel core bearing mechanical stress and the outer aluminum stranded wires transmitting electrical energy. Some lines use carbon fiber core conductors or aluminum alloy conductors to improve performance or reduce costs. Insulators are classified into porcelain insulators, glass insulators, and composite insulators. Porcelain and glass insulators are distinguished by the number of insulators (e.g., 6 insulators correspond to 66kV, and approximately 10 insulators correspond to 110kV), while composite insulators are used for pollution flashover protection.
[0003] The installation of cable terminations on common 110kV cable terminal towers often lacks demagnetization requirements, which can easily generate electromagnetic eddy currents, leading to power loss and interference with surrounding communication equipment and sensors. Austenitic stainless steel is commonly used as a demagnetizing material, but it is relatively expensive and requires post-processing; there are no ready-made cable terminations that directly match it. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a component device for the non-magnetic installation of 110kV line cable terminations.
[0005] To achieve the above objectives, this utility model provides a component device for non-magnetic installation of 110kV line cable terminations, including a mounting plate made of ceramic material. One side of the mounting plate has a wire-passing groove, and the other side has a wire-placement groove. The inner walls of the wire-passing groove and the wire-placement groove are connected. One side of the mounting plate has four first fixing holes, and both sides of the mounting plate are provided with reinforcement structures.
[0006] In the above technical solution, the cost is further reduced by replacing austenitic stainless steel with ceramic tile products that have high plasticity before firing. This solution is highly versatile, easy to install, and easy to mass-produce by matching with the terminal base of common 110kV lines. It can achieve a low-cost solution to meet the requirements of non-magnetic installation of cable terminals and cable platforms.
[0007] Preferably, the reinforcement structure includes two clamps in an arc shape. The inner walls of each clamp are fixedly connected with a resistance-increasing layer. A first connecting rod is fixedly connected to the surface of each clamp. The first connecting rod is L-shaped, and a second connecting rod is fixedly connected to one end of the first connecting rod.
[0008] In the above technical solution, the reinforcement structure can be made of insulating metal to avoid magnetization of the cable terminal as much as possible. The two arc-shaped clamps can clamp and fix the cable terminal close to each other. The resistance layer can be made of rubber, which can increase the resistance of the contact between the clamp and the cable terminal, and also achieve the effect of insulation and non-magnetization.
[0009] Preferably, a first limiting member is fixedly connected to one side of the mounting plate. The first limiting member is T-shaped, and the inner cavity of the first connecting rod is slidably connected to the surface of the first limiting member. In the above technical solution, the T-shaped first limiting member can connect the clamping plate, and the clamping plate can slide stably along one side of the mounting plate through the first limiting member.
[0010] Preferably, both sides of the mounting plate are fixedly connected to connectors, and the connectors are all U-shaped, with a support plate fixedly connected to the other end of each connector. In the above technical solution, the support plate further provides support for the adjustment components of the reinforcement structure, and the U-shaped connector can ensure the firmness between the mounting plate and the support plate.
[0011] Preferably, the inner cavity of the support plate is rotatably connected to an adjusting screw, the surface of the adjusting screw is threadedly connected to a transmission sleeve, and the surface of the transmission sleeve is fixedly connected to a connecting block. In the above technical solution, the transmission sleeve and the connecting block are integrally formed and can be regarded as transmission components, and the adjusting screw can be regarded as the adjusting component of the reinforcement structure. The convenience of adjusting the reinforcement structure can be improved by adjusting the adjusting screw.
[0012] Preferably, two first transmission rods are rotatably connected to both sides of the connecting block, and the other end of each of the two first transmission rods is rotatably connected to one side of a second connecting rod.
[0013] In the above technical solution, the other end of the first transmission rod pushes or pulls the clamping plates in the reinforcement structure to move closer or further apart, improving the convenience of clamping plate adjustment, and ensuring the stability of the clamping plates through the self-locking characteristic of the threads.
[0014] Preferably, a connecting seat is fixedly connected to one side of the support plate, and auxiliary rods are rotatably connected to both sides of the connecting seat. One end of each auxiliary rod is rotatably connected to one side of the first transmission rod.
[0015] Furthermore, in the above technical solution, the auxiliary rod can rotate stably along the connecting seat, and the auxiliary rod can improve the stability of the first transmission rod.
[0016] Preferably, the surface of the mounting plate is slidably connected with a sealing block, and there are two sealing blocks. Both sealing blocks are set at the port of the wire groove. An extension plate is fixedly connected to one side of each sealing block, and a second fixing hole is opened on one side of the extension plate.
[0017] In the above technical solution, the two sealing blocks can seal the port of the cable tray while moving closer and merging together, so as to avoid the cable terminal head from detaching from the cable tray as much as possible.
[0018] Preferably, a second transmission rod is rotatably connected to both sides of the sealing block, and the other end of the second transmission rod is rotatably connected to one side of the corresponding clamping plate.
[0019] In the above technical solution, the two sealing blocks are fixed to each other to seal the cable tray port, and the clamping plate can be pulled by the second transmission rod to further improve the firmness of the clamping plate in fixing the cable terminal head.
[0020] Preferably, a second limiting member is fixedly connected to one side of the mounting plate, and the inner cavity of the sealing block is slidably connected to the surface of the second limiting member.
[0021] In the above technical solution, the sealing block slides along the surface of the mounting plate while the inner cavity slides along the surface of the second limiting member, thereby improving the stability of the sealing block.
[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. The mounting plate plays a primary role in installing and supporting the cable termination. By replacing austenitic stainless steel with ceramic tiles that have high plasticity before firing, the cost is reduced. This solution is compatible with common 110kV line termination bases, making it highly versatile, easy to install, and suitable for mass production. It can achieve a low-cost solution to meet the requirement of non-magnetic installation of cable terminations and cable platforms.

The reinforcement structure can strengthen the cable termination and improve its stability. 2. The reinforcement structure can be made of insulating metal to avoid magnetization of the cable terminal as much as possible. Two arc-shaped clamps close to each other can clamp and fix the cable terminal. The resistance layer can be made of rubber, which can increase the resistance of the contact between the clamp and the cable terminal, and also achieve the effect of insulation and non-magnetization. 3. When the two sealing blocks approach and merge, they can seal the port of the cable tray to prevent the cable terminal from detaching from the cable tray as much as possible. The two sealing blocks are sealed by inserting a fixing bolt into the second fixing hole of the extension plate to ensure the firmness of the two sealing blocks when they are merged.

Detailed Implementation
[0025] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] like Figure 1 - Figure 5 The illustrated component device for non-magnetic installation of 110kV line cable terminations includes a mounting plate 1 made of ceramic material. One side of the mounting plate 1 has a wire-passing groove 2, and another side has a wire-placement groove 3. The inner walls of the wire-passing groove 2 and the wire-placement groove 3 are connected. Four first fixing holes 4 are provided on one side of the mounting plate 1. Reinforcing structures 5 are provided on both sides of the mounting plate 1. In this component device for non-magnetic installation of 110kV line cable terminations, the mounting plate 1 plays a primary role in installation and support. The purpose of supporting the cable termination head is to reduce costs by using ceramic tiles with high plasticity before firing instead of austenitic stainless steel. This solution is compatible with common 110kV line termination head bases, has strong versatility, is easy to install, and is suitable for mass production. It can achieve a low-cost solution to the requirement of non-magnetic installation of cable termination heads and cable platforms. The cable termination head is installed in the cable placement groove 3 through the cable passage groove 2. The mounting plate 1 and the termination head base are fixed by a fixing bolt passing through the first fixing hole 4. The reinforcement structure 5 can reinforce the cable termination head and improve its stability.
[0027] like Figure 1 - Figure 3As shown, the reinforcing structure 5 includes two clamping plates 501, each with an arc shape. A resistance-enhancing layer 502 is fixedly connected to the inner wall of each clamping plate 501. A first connecting rod 503, L-shaped, is fixedly connected to the surface of each clamping plate 501. A second connecting rod 504 is fixedly connected to one end of each first connecting rod 503. The reinforcing structure 5 can be made of insulating metal to minimize magnetization of the cable termination. The two arc-shaped clamping plates 501, close together, can clamp and fix the cable termination. The resistance-enhancing layer 502 can be made of rubber, which increases the resistance between the clamping plate 501 and the cable termination, and also provides insulation and prevents magnetization. The clamping plates 501, the first connecting rod 503, and the second connecting rod 504 are integrally formed. The first connecting rod 503 and the second connecting rod 504 allow the clamping plates 501 to be installed on one side of the mounting plate 1, facilitating adjustment of the spacing between the clamping plates 501.

The inner cavity of the first connecting rod 503 is slidably connected to the surface of the first limiting member 6. Through the first limiting member 6, the T-shaped first limiting member 6 can connect the clamping plate 501, and the clamping plate 501 can slide stably along one side of the mounting plate 1 through the first limiting member 6. like Figure 1 As shown, both sides of the mounting plate 1 are fixedly connected to connectors 7, and the connectors 7 are all U-shaped. The other end of the connectors 7 is fixedly connected to a support plate 8. Through the connectors 7, the support plate 8 provides support for the adjustment of the reinforcing structure 5. The U-shaped connectors 7 can ensure the firmness between the mounting plate 1 and the support plate 8. like Figure 1 and Figure 4 As shown, an adjusting screw 9 is rotatably connected to the inner cavity of the support plate 8. A transmission sleeve 10 is threadedly connected to the surface of the adjusting screw 9. A connecting block 11 is fixedly connected to the surface of the transmission sleeve 10.

The other ends of the two first transmission rods 12 are rotatably connected to one side of the second connecting rod 504. Through the first transmission rods 12, the transmission sleeve 10 and the connecting block 11 can push or pull the first transmission rods 12 while sliding up and down along the surface of the adjusting screw 9. The other end of the first transmission rods 12 pushes or pulls the clamping plates 501 in the reinforcing structure 5 to move closer or further away from each other, improving the convenience of adjusting the clamping plates 501, and ensuring the stability of the clamping plates 501 through the self-locking characteristics of the threads.

[0030] like Figure 1 and Figure 5 As shown, two sealing blocks 15 are slidably connected to the surface of the mounting plate 1. Both sealing blocks 15 are located at the port of the cable tray 2. An extension plate 16 is fixedly connected to one side of each sealing block 15. A second fixing hole 17 is provided on one side of the extension plate 16. By using the sealing blocks 15, the two sealing blocks 15 can seal the port of the cable tray 2 while approaching and merging with each other, so as to prevent the cable terminal head from detaching from the cable tray 2 as much as possible. The two sealing blocks 15 are sealed by inserting a fixing bolt into the second fixing hole 17 of the extension plate 16, so as to ensure the firmness of the two sealing blocks 15 when they are merged.

The other end of the second transmission rod 18 is rotatably connected to one side of the corresponding clamping plate 501. Through the second transmission rod 18, the two clamping plates 501 can pull the second transmission rod 18 when they move closer to each other. The other end of the second transmission rod 18 pulls the corresponding sealing block 15 to slide. The two sealing blocks 15 are fixed to each other to close the port of the cable tray 2. At the same time, the clamping plate 501 can be pulled by the second transmission rod 18, which further improves the firmness of the clamping plate 501 in fixing the cable terminal head.

The inner cavity of the sealing block 15 is slidably connected to the surface of the second limiting member 19. Through the second limiting member 19, the sealing block 15 slides along the surface of the mounting plate 1 while the inner cavity slides along the surface of the second limiting member 19, thereby improving the stability of the sealing block 15.
[0033] Working Principle: Mounting plate 1 primarily serves to install and support the cable termination. Replacing austenitic stainless steel with a ceramic tile product that has high plasticity before firing reduces costs. This solution is compatible with common 110kV line termination bases, offering strong versatility, convenient installation, and ease of mass production. It achieves a low-cost solution for non-magnetic installation of the cable termination and cable platform. The cable termination is installed in the cable tray 3 via the cable channel 2. A fixing bolt passes through the first fixing hole 4 to fix the mounting plate 1 to the termination base. The reinforcing structure 5 can be made of insulating metal to minimize magnetization of the cable termination. Two arc-shaped clamping plates 501, close together, clamp and fix the cable termination. The resistance-enhancing layer 502... The use of rubber material increases the resistance between the clamp 501 and the cable terminal head, while also providing insulation and demagnetization. The clamp 501, the first connecting rod 503, and the second connecting rod 504 are integrally formed. By rotating the adjusting screw 9, the transmission sleeve 10 and the connecting block 11 can slide up and down along the surface of the adjusting screw 9, while simultaneously pushing or pulling the first transmission rod 12. The other end of the first transmission rod 12 pushes or pulls the clamp 501 in the reinforcement structure 5 to move closer or further apart. As the clamp 501 continues to move closer together, the resistance-increasing layer 502 can contact and clamp the cable terminal head, improving the ease of adjustment of the clamp 501. Furthermore, the self-locking characteristic of the thread ensures the stability of the clamp 501.
