Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a novel single-circuit tower. Background Technology

[0002] The poles and towers of overhead transmission lines are supporting structures used to support the power lines. They are mostly made of steel and are one of the important pieces of equipment for overhead transmission lines. Currently, the single-circuit towers used in engineering are all of the conventional type (turning angle from 0° to 90°). When encountering a turning angle of more than 90 degrees, it is only possible to achieve a line switching of more than 90 degrees by using two turning towers in two turns, and a large tower erection space is required on site.

[0003] Currently, due to the increasing influence of external factors on the path of high-voltage transmission lines, there is often only one path to avoid obstacles, and there are often paths with turning angles exceeding 90°. Using existing technologies may make the solution infeasible, or the use of two corner towers for connection may cause difficulties in project implementation and be uneconomical. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a new type of single-circuit tower that can adopt the feature of arranging hanging points on the same side, which effectively solves the problem of the line needing to turn 90° to 170° in areas with restricted paths.

[0005] The present invention is implemented by the following method: a new type of single-circuit tower, including a tower body (1), conductor hanging points (4) and ground wire hanging points (5). The tower body (1) adopts a steel structure frame design, and is generally conical with a wider bottom and a gradually narrower top. The total height of the tower body is 12000 mm, which is divided into four main parts, each with a height of 4000 mm. The tower body (1) is composed of multiple horizontal beams (2) and diagonal braces (3). The horizontal beams (2) and diagonal braces (3) are connected by bolts and fixed by welding. Three conductor hanging points (4) are set on each of the left and right sides of the small side of the tower body (1), for a total of 6 conductor hanging points (4). The conductor hanging points (4) are located on the horizontal beams (2) at different heights, specifically 1200 mm, 1560 mm, 1920 mm and 2280 mm respectively. The minimum interval between the conductor hanging points (4) is greater than 1.56 meters. A ground wire hanging point (5) is set on each side of the top of the tower.

[0006] Furthermore, the angle between the diagonal brace (3) at the bottom of the tower body (1) and the ground is 45 degrees, and it is fixed by high-strength bolts.

[0007] Furthermore, the tower body (1) is equipped with an insulator string (14) at the conductor suspension point (4). The insulator string (14) is 1500 mm long and made of tempered glass.

[0008] Furthermore, the wire hanging point (4) is made of high-strength alloy steel and its surface is hot-dip galvanized.

[0009] Furthermore, small side conductors A (6), B (7), and C (8) are all hung on the D leg side (12) of the tower, while large side conductors A (9), B (10), and C (11) are hung on the C leg side (13) of the tower. Each conductor is directly connected from one hanging point to the next hanging point without any additional joints in between.

[0010] Furthermore, the connection between the wire and the hanging point adopts a double-nut locking structure.

[0011] The beneficial effects of this utility model are as follows: Compared with the traditional two-tower corner tower scheme, this new tower only requires one tower to complete a large-angle turn, reducing construction difficulty and cost; secondly, this utility model is applicable to high-voltage transmission lines in areas with restricted routes, improving the flexibility and adaptability of line layout; thirdly, by reducing the number of towers and construction complexity, the project cost is significantly reduced; finally, by reducing intermediate joints through direct jump connection, the reliability and safety of the line are improved; in particular, this utility model also achieves the technical goal of a minimum gap between conductor hanging points greater than 1.56 meters by optimizing the arrangement of hanging points and conductor connection methods; the optimized wind and earthquake resistance performance in the tower structure design ensures the long-term stable operation of the tower in harsh environments; in particular, the selection of materials and surface treatment processes for conductor hanging points effectively extends the service life of the tower and reduces maintenance costs; the technical solution of this utility model is not only theoretically innovative, but also shows significant advantages in practical applications; through reasonable structural design and material selection, this utility model can meet the electrical safety and mechanical stability requirements under different corner conditions, providing a new solution for the design and construction of high-voltage transmission lines.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please see Figures 1 to 3As shown, this utility model provides an embodiment: the tower body 1 of this novel single-loop tower adopts a steel frame design, with an overall conical shape, wider at the bottom and gradually narrowing at the top, and a total height of 12000mm. The tower body is divided into four main parts, each with a height of 4000mm. The tower body 1 is composed of multiple horizontal beams 2 and diagonal braces 3, forming a stable frame structure to ensure sufficient strength and rigidity when bearing conductors and ground wires. The horizontal beams 2 and diagonal braces 3 are connected by bolts and further fixed by welding to enhance overall stability. The diagonal braces 3 at the bottom of the tower body form a 45° angle with the ground and are fixed by high-strength bolts to improve the overall anti-overturning capacity of the tower body. This structural design not only meets the mechanical performance requirements but has also been optimized for wind and earthquake resistance, enabling long-term stable operation under harsh weather conditions. The arrangement of conductor hanging points 4 is one of the core technologies of this utility model. Three conductor hanging points 4 are set on each of the left and right sides of the smaller side of the tower body 1, for a total of six conductor hanging points 4. The suspension points are located on horizontal beams 2 at different heights: 1200mm, 1560mm, 1920mm, and 2280mm. The minimum spacing between the conductor suspension points 4 is greater than 1.56 meters. This design meets electrical safety regulations and avoids electric field interference or safety hazards caused by insufficient clearance. In addition, a ground wire suspension point 5 is installed on each side of the tower top for suspending the ground wire, ensuring grounding protection of the power system. Each conductor suspension point 4 is equipped with an insulator string 14, which is 1500mm long and made of tempered glass, ensuring good electrical insulation performance even under harsh weather conditions.

[0017] The conductor connection method adopts a direct jump connection, which is another key technical feature of this utility model. Small side conductors A6, B7, and C8 are all hung on the D leg side 12 of the tower, while large side conductors A9, B10, and C11 are hung on the C leg side 13 of the tower. Each conductor jumps directly from one hanging point to the next without any additional joints, reducing the risk of failure due to loose or aging joints. The connection between the conductor and the hanging point uses a double-nut locking structure to ensure a firm and reliable connection. The conductor routing has been optimized based on mechanical analysis and electric field distribution simulation to ensure uniform tension distribution at different turning angles and avoid localized stress concentration.

[0018] This design enables the tower to accommodate turning angles from 90° to 170°, solving the complexity and high cost of traditional two-tower turning towers requiring two separate turns. In practical applications, this invention demonstrates significant advantages. For example, in a high-voltage transmission line project, a large-angle turn of 135° is required in a route-restricted area. Traditional solutions require two towers for two turns, while this invention requires only one tower. During construction, horizontal beams 2 and diagonal braces 3 are first installed on the tower body 1 according to the design drawings, forming a stable frame structure. Then, according to the design height, six conductor suspension points 4 are installed on the left and right sides of the smaller side of the tower body 1, and ground wire suspension points 5 are installed on both sides of the tower top. The conductor suspension points 4 are made of high-strength alloy steel with a hot-dip galvanized surface to improve corrosion resistance and service life. Next, the small side conductors A6, B7, and C8 were hung on leg D side 12, and the large side conductors A9, B10, and C11 were hung on leg C side 13, using a straight-jump connection method to complete the conductor connection. Finally, all connection points were checked to ensure the double-nut locking structure was secure and reliable. To verify the actual effect of this utility model, multiple sets of experimental tests were conducted. The experimental results show that the tower body 1 will not deform or displace when subjected to the maximum load, and the position of the conductor hanging point 4, after static and dynamic analysis, ensures that it can meet the strength requirements under various working conditions. The electrical performance test of the insulator string 14 shows that it can still maintain good insulation performance under high humidity and strong wind conditions. The optimized design of the conductor routing effectively reduces local stress concentration and improves the overall mechanical stability. In addition, the precise calculation of the position of each hanging point through three-dimensional modeling further improves the construction accuracy and operational reliability.

[0019] The tower structure design of this utility model also includes several detailed optimizations. For example, the diagonal brace 3 at the bottom of the tower body 1 forms a 45° angle with the ground and is fixed with high-strength bolts, improving the overall anti-overturning capacity of the tower body. The conductor suspension point 4 at the top of the tower body is equipped with an insulator string 14, which is 1500mm long and made of tempered glass, ensuring good electrical insulation performance even under harsh weather conditions. The installation position of the conductor suspension point 4 is precisely calculated through 3D modeling, and the position of each suspension point has undergone static and dynamic analysis to ensure that it will not deform or shift under maximum load. The suspension points are made of high-strength alloy steel with a hot-dip galvanized surface treatment, improving corrosion resistance and service life.

[0020] The technical solution of this utility model exhibits significant advantages in several aspects. First, compared with the traditional two-tower corner tower scheme, this new tower only requires one to complete a large-angle turn, reducing construction difficulty and cost. Second, this utility model is applicable to high-voltage transmission lines in areas with restricted routes, improving the flexibility and adaptability of line layout. Third, by reducing the number of towers and construction complexity, the project cost is significantly reduced.

[0021] Finally, by reducing intermediate joints through direct-jump connections, the reliability and safety of the line are improved. This invention also achieves the technical goal of a minimum gap of more than 1.56 meters between conductor suspension points by optimizing the arrangement of suspension points and conductor connection methods, further enhancing electrical safety performance. In practical applications, this novel single-circuit tower not only solves the problem of existing technologies being unable to achieve large-angle turns of 90° to 170° in one go, but also meets the electrical safety and mechanical stability requirements under different turning angle conditions through reasonable structural design and material selection. Optimized wind and earthquake resistance in the tower structure design ensures the long-term stable operation of the tower in harsh environments. The selection of materials and surface treatment processes for conductor suspension points effectively extends the service life of the tower and reduces maintenance costs. This invention's technical solution is not only theoretically innovative but also demonstrates significant advantages in practical applications, providing a new solution for the design and construction of high-voltage transmission lines.
