Description

Technical Field

[0001] This utility model belongs to the technical field of conductor spacer bars, and specifically relates to a double-split conductor spacer bar. Background Technology

[0002] In power transmission systems, double-split conductors are widely used in high-voltage transmission lines to improve transmission capacity and reduce corona losses. Double-split conductors consist of two or more conductors per phase, with a certain spacing between them to prevent collisions, friction, and short circuits caused by insufficient spacing. To achieve this, double-split conductor spacers have been developed.

[0003] Double-split conductor spacers are key components in power transmission lines, primarily functioning to fix the spacing between the double-split conductors and withstand various external forces such as tension and wind transmitted by the conductors. With the continuous development of power systems and increasing demands for transmission reliability, higher requirements have been placed on the performance and structural design of double-split conductor spacers. Traditional double-split conductor spacers have revealed some problems in practical applications and can no longer fully meet the needs of modern power transmission. The structure of traditional double-split conductor spacers may be relatively simple, making it difficult to effectively disperse and withstand stress under the influence of external forces such as wind and conductor galloping, easily leading to structural deformation or even damage, thus affecting the normal use of the spacer and the safe operation of the conductors. For example, some spacers with simple frame structures may experience frame twisting and clamp displacement in strong winds. Some traditional spacers use crescent-shaped crossplates, a rather unusual shape that easily leads to stress concentration in certain areas when subjected to tension and wind transmitted by the conductors, reducing the service life of the crossplate. Furthermore, the crescent-shaped crossbar has certain limitations in space utilization, making it difficult to rationally arrange components such as clamp assemblies and connecting rods, resulting in a less compact overall structure of the spacer. In addition, the curved shape of the crescent-shaped crossbar requires more complex processing techniques, increasing manufacturing costs and time. The clamp assemblies of traditional double-split conductor spacers are usually of fixed specifications, only suitable for conductors of a specific diameter. When it is necessary to replace conductors of different diameters, the entire spacer often needs to be replaced, increasing maintenance costs and workload.

[0004] In view of this, we propose a double-split conductor spacer to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problem that the clamp assembly of the double-split conductor spacer in the prior art is not easy to adjust and replace to adapt to conductors of different sizes. The structure of the traditional double-split conductor spacer may be relatively simple, and it is difficult to effectively disperse and bear stress when subjected to external forces such as wind and conductor galloping, which can easily lead to structural deformation or even damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A double-split conductor spacer includes a spacer body and a clamp assembly. The clamp assembly is used to clamp the double-split conductor. The clamp assembly has two sets and is disposed at both ends of the spacer body.

[0008] The spacer body includes two isosceles trapezoidal horizontal plates arranged opposite each other front and back, and a connecting rod symmetrically arranged above and below and connecting the two isosceles trapezoidal horizontal plates. The two isosceles trapezoidal horizontal plates are detachably connected by the connecting rod to form an isosceles trapezoidal frame structure. Two sets of wire clamp assemblies are respectively set at both ends of the isosceles trapezoidal horizontal plates. The wire clamp assemblies are detachably connected to the spacer body by bolt A.

[0009] Preferably, the included angle between the two sets of clamp assemblies and the spacer body is 90-120°.

[0010] Preferably, the wire clamp assembly includes an upper clamp body and a lower clamp body. Both the upper and lower clamp bodies have arc-shaped grooves on their inner sides. The inner wall of the arc-shaped grooves is provided with a rubber pad layer to increase the friction with the wire while avoiding damage to the wire.

[0011] Preferably, the upper clamp is inserted between two isosceles trapezoidal horizontal plates, and bolt A is set through the positioning holes on the upper clamp and the isosceles trapezoidal horizontal plates. Nuts A are threaded to both ends of bolt A, and the two isosceles trapezoidal horizontal plates and the upper clamp are connected together by the cooperation of bolt A and nut A.

[0012] Preferably, by disassembling bolt A and nut A, the wire clamp assembly can be replaced, and by replacing the upper and lower clamps with arc-shaped grooves of different diameters, the rubber pads with different inner diameters can be replaced, so that the wire clamp assembly can adapt to wires of different diameters.

[0013] Preferably, one end of the upper clamp is rotatably connected to the lower clamp via a rotating connecting shaft, and the other end is locked and fixed together with the lower clamp via bolts and nuts.

[0014] Preferably, the corners of the isosceles trapezoidal horizontal plate are chamfered, and a guide block is fixed on the upper clamp to guide the sliding of the outer corner of the isosceles trapezoidal horizontal plate.

[0015] Preferably, nuts B are threaded to both ends of the connecting rod, and the two isosceles trapezoidal horizontal plates and the wire clamp assembly are connected together by the cooperation of the connecting rod and nuts B.

[0016] Preferably, a limiting post is fixedly provided on the isosceles trapezoidal horizontal plate to cooperate with the clamping body for limiting.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are as follows: The spacer body of the double-split conductor spacer consists of two isosceles trapezoidal horizontal plates facing each other front and back and symmetrical connecting rods. The horizontal plates and the clamp assembly are connected by nuts B at both ends of the connecting rods to form a stable isosceles trapezoidal frame structure. The upper and lower clamps of the clamp assembly are connected by a rotating connecting shaft, and one end is locked with a bolt and nut. The rubber pad in the inner arc-shaped groove can increase the friction with the conductor. Two sets of clamp assemblies are set at both ends of the spacer body and connected to the horizontal plates by bolts A and nuts A. During operation, the clamp assembly uses the friction of the rubber pad to firmly clamp the double-split conductor. The spacer body disperses and bears the external force transmitted by the conductor by means of the isosceles trapezoidal frame. The limiting post ensures that the angle between the two sets of clamp assemblies and the body is within a suitable range, maintaining the conductor spacing.

[0018] In terms of structural design, the isosceles trapezoidal frame structure has significant advantages. Compared to simpler structures, it has better geometric stability, and can better distribute and withstand stress under external forces such as wind and conductor galloping, reducing structural deformation and ensuring the overall stability and reliability of the spacers. The detachable connection method makes installation and maintenance more convenient, allowing components to be transported to the site for assembly separately, and also facilitating component replacement and maintenance. Furthermore, the isosceles trapezoidal crossbar is superior to the traditional crescent-shaped crossbar; its regular shape can evenly distribute stress, extending service life; it facilitates the rational arrangement of components, resulting in a compact structure; and it is simple to manufacture, reducing costs and complexity.

[0019] The rubber padding layer increases friction to prevent conductor slippage, avoids direct contact between the clamp and the conductor, reduces wear, and extends conductor life. The rotating and bolted connection design of the clamp assembly makes conductor installation and removal easy and convenient. The detachable connection between the clamp assembly and the spacer bar body allows for replacement of conductors of different diameters simply by replacing the clamp assembly, improving versatility and applicability, and reducing maintenance costs. Limiting posts ensure proper conductor spacing, reducing interference and short-circuit risks, and optimizing conductor stress. The rounded chamfer and guide block design prevents scratching of conductors and components, improving installation efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The following combination Figures 1 to 4 This application will be described in further detail.

[0027] This application discloses a double-split conductor spacer, including a spacer body and a clamp assembly 3. The clamp assembly 3 is used to clamp the double-split conductor, and the clamp assembly 3 is provided in two sets and disposed at both ends of the spacer body.

[0028] The spacer body includes two isosceles trapezoidal horizontal plates 1 arranged opposite each other front and back, and a connecting rod 2 arranged symmetrically on top and bottom and connecting the two isosceles trapezoidal horizontal plates 1. The two isosceles trapezoidal horizontal plates 1 are detachably connected by the connecting rod 2 to form an isosceles trapezoidal frame structure. Nuts B6 are threaded to both ends of the connecting rod 2. The two isosceles trapezoidal horizontal plates 1 and the wire clamp assembly 3 are connected together by the cooperation of the connecting rod 2 and the nut B6.

[0029] The isosceles trapezoidal frame structure, consisting of the isosceles trapezoidal horizontal plate 1 and the connecting rod 2, has better geometric stability compared to some simpler structures. When subjected to external forces (such as wind or conductor galloping), the isosceles trapezoidal frame can better distribute and bear stress, reduce the possibility of structural deformation, and ensure the overall stability and reliability of the spacer.

[0030] Two isosceles trapezoidal horizontal plates 1 are detachably connected by connecting rod 2 and nut B6. This design makes the spacer bar more convenient to install and maintain. During on-site construction, each component can be transported to the installation site separately and then assembled; it can also be easily disassembled when it is necessary to replace components or inspect the spacer bar.

[0031] The isosceles trapezoidal horizontal plate 1 has a relatively regular shape, which allows for more even distribution of stress when subjected to external forces such as tension transmitted by conductors and wind. In contrast, the traditional crescent-shaped horizontal plate has a more unusual shape, which may cause stress to concentrate in certain areas, thereby reducing the service life of the horizontal plate.

[0032] The isosceles trapezoidal horizontal plate 1 is more conducive to the rational arrangement of components such as the wire clamp assembly 3 and the connecting rod 2, and can make more efficient use of space, making the overall structure of the spacer bar more compact. In contrast, the shape of the crescent-shaped horizontal plate may have certain limitations in terms of space utilization. The shape of the isosceles trapezoidal horizontal plate 1 is relatively simple, making it easier to process and shape during manufacturing, which can reduce production costs and manufacturing difficulty. However, the curved shape of the crescent-shaped horizontal plate requires more complex processing technology, which may increase manufacturing costs and time.

[0033] The wire clamp assembly 3 includes an upper clamp body 31 and a lower clamp body 32. Both the upper clamp body 31 and the lower clamp body 32 have arc-shaped grooves 33 on their inner sides. The inner wall of the arc-shaped grooves 33 is provided with a rubber pad layer 34 to increase the friction with the wire while preventing damage to the wire. One end of the upper clamp body 31 is rotatably connected to the lower clamp body 32 through a rotating connecting shaft 35, and the other end is locked and fixed together with the lower clamp body 32 by bolts and nuts.

[0034] The inner walls of the arc-shaped grooves 33 on the inner sides of the upper clamp 31 and the lower clamp 32 are provided with rubber pads 34. The rubber pads 34 have good elasticity and flexibility, which can increase the friction with the wire, ensuring that the clamps firmly hold the wires and prevent the wires from sliding inside the spacers. At the same time, the rubber pads 34 can prevent the clamps from directly contacting the wires, reducing wear and damage to the wires and extending the service life of the wires.

[0035] One end of the upper clamp 31 is rotatably connected to the lower clamp 32 via a rotating connecting shaft 35, and the other end is locked and fixed to the lower clamp 32 with bolts and nuts. This design makes it very convenient to install wires in the wire clamp assembly 3; simply place the wire into the arc-shaped groove 33, then rotate the upper clamp 31 and tighten the bolts and nuts. The wire clamp can also be easily removed when it is necessary to replace the wire or maintain the spacer.

[0036] Two sets of wire clamp assemblies 3 are respectively installed at both ends of the isosceles trapezoidal horizontal plate 1. The wire clamp assembly 3 is detachably connected to the spacer bar body by bolts A4. The upper clamp body 31 is inserted between the two isosceles trapezoidal horizontal plates 1. Bolts A4 are installed through the positioning holes on the upper clamp body 31 and the isosceles trapezoidal horizontal plate 1, and nuts A5 are threaded to both ends of bolts A4. The two isosceles trapezoidal horizontal plates 1 and the upper clamp body 31 are connected together by the cooperation of bolts A4 and nuts A5. By removing bolts A4 and nuts A5, the wire clamp assembly 3 can be replaced. By replacing the upper clamp body 31 and lower clamp body 32 with different diameter arc-shaped grooves 33, the rubber pads 34 with different inner diameters can be replaced, so that the wire clamp assembly 3 can adapt to wires of different diameters.

[0037] The wire clamp assembly 3 can be easily replaced by disassembling bolt A4 and nut A5. When it is necessary to clamp wires of different diameters, simply replace the upper clamp 31 and lower clamp 32 with arc-shaped grooves 33 of different diameters, as well as the rubber pads 34 with corresponding inner diameters. This allows the wire clamp assembly 3 to adapt to wires of different diameters, improving the versatility and applicability of the spacer. If the wire clamp assembly 3 is damaged or worn, only the wire clamp assembly 3 needs to be replaced, without replacing the entire spacer, reducing maintenance costs and repair time.

[0038] A limiting post 11 is fixed on the isosceles trapezoidal horizontal plate 1 to cooperate with the clamp body 31 for limiting. The limiting post 11 makes the included angle between the two sets of wire clamp assemblies 3 and the spacer body between 90-120°.

[0039] The limiting post 11 ensures that the angle between the two sets of clamp assemblies 3 and the spacer body is between 90° and 120°. This angle range ensures that the double-split conductors maintain a suitable spacing, reducing mutual interference and collision between conductors and lowering the risk of short circuits and other faults. At the same time, a suitable angle also helps to optimize the stress state of the conductors, improving their safety and stability.

[0040] The corners of the isosceles trapezoidal horizontal plate 1 are chamfered, and the upper clamp 31 is fixed with a guide block 36 that slides along the outer corner of the isosceles trapezoidal horizontal plate 1.

[0041] The edges and corners of the isosceles trapezoidal horizontal plate 1 are rounded and chamfered to prevent scratches to wires or other components during installation and use, thus protecting the wires and other related equipment. A guide block 36 is fixedly mounted on the upper clamp 31 to guide the sliding motion along the outer corner of the isosceles trapezoidal horizontal plate 1. During the installation of the wire clamp assembly 3, the guide block 36 can slide along the outer corner of the isosceles trapezoidal horizontal plate 1, providing guidance and making the installation of the wire clamp assembly 3 more accurate and convenient, thereby improving installation efficiency.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
