Description

Technical Field

[0001] The utility model belongs to the technical field of hardware for electric power engineering, in particular to a double-headed special-shaped high-strength tension-resistant component. Background Art

[0002] During the installation of transmission lines, iron towers are usually used for support. However, the lines and iron towers cannot be in direct contact to prevent discharge. Therefore, insulator strings are usually used for isolation. Insulator strings mainly play an insulating role. Therefore, in order to make the connection between them and the cables and iron towers more firm, tension components are usually installed at both ends of the insulator strings. The tension components are also called suspension fittings. Their core function is to firmly suspend the cables on the iron towers and provide the necessary mechanical strength to withstand changes in wind, ice loads and temperature.

[0003] Chinese patent CN114883066A discloses a ground wire tension insulator string, comprising a main tension fitting, a standby tension fitting, an upper connecting plate, an insulator string, a lower connecting plate and a tension wire clamp, wherein two standby tension fittings are symmetrically arranged on both sides of the main tension fitting, and when the main tension fitting bears force, the standby tension fittings are bent, that is, when the main tension fitting bears force, the standby tension fittings do not bear force, and the inner and outer limbs are balanced in force, and when the main tension fitting is disconnected from the cross arm, the two standby tension fittings bear force, and since the standby tension fittings are symmetrically arranged on both sides of the main tension fittings, the inner and outer limbs are balanced in force at this time, and after a fault occurs, the ground wire tension insulator string increases, which is beneficial to reducing the tension in the tension section, preventing the ground wire disconnection fault, and improving the reliability of the transmission line.

[0004] It can be seen that the existing power lines are usually installed with traditional tension strings with standard geometric shapes (such as straight segments). After installation, the tension strings with standard geometric shapes may cause stress concentration at the connection points or bends, which will accelerate fatigue damage of the material and shorten the service life.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The special-shaped tension components in this application are suspension fittings of special shapes used to support conductors in power transmission lines. They have unique geometric structures to adapt to specific installation environments and mechanical requirements. Compared with traditional straight-plate tension components, the main advantage of special-shaped tension components is that they can provide better mechanical properties and adaptability. The design of special-shaped tension components can optimize stress distribution and reduce stress concentration, thereby improving the bearing capacity and durability of the structure.

[0017] (2) The special-shaped tension components in this application can adapt to different installation conditions, such as different line curvatures and inclination angles, by adjusting their shapes, and have a certain degree of flexibility, thereby making the application of special-shaped tension components in complex terrains and special environments more feasible. Special-shaped tension components are increasingly used in power systems, especially in high-voltage and ultra-high-voltage transmission lines, which can effectively support conductors while reducing line losses and improving transmission efficiency.

By staggering the vertical position of the connection between the cable and the tower, it helps to disperse the stress of the cable and improve the tensile strength and durability of the cable.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0032] Figure 1 and Figure 2 This is an assembly diagram of the tension component in this embodiment. In this embodiment, the double-headed special-shaped tension component includes a tower-end special-shaped hanging plate 100 and a line-end special-shaped hanging plate 200. An insulator string 300 is connected between the tower-end special-shaped hanging plate 100 and the line-end special-shaped hanging plate 200. The tower-end special-shaped hanging plate 100 and the line-end special-shaped hanging plate 200 are present as transition pieces between the insulator string 300 and the cable or the tower. The insulator string 300 separates the cable from the tower to prevent the current on the cable from being transferred to the tower and causing ground discharge. The tower-end special-shaped hanging plate 100 and the line-end special-shaped hanging plate 200 are used to support the conductors in the power transmission line. Since the tower-end special-shaped hanging plate 100 and the line-end special-shaped hanging plate 200 have a unique geometric structure, compared with the traditional straight plate tension component, they can provide better mechanical properties and adaptability, optimize stress distribution, reduce stress concentration, and thus improve the bearing capacity and durability of the structure.

[0033] Figure 3 It is one of the double-headed special-shaped high-strength tension-resistant components in this embodiment. The tower end special-shaped hanging plate 100 in this embodiment includes a tower hanging vertical plate 101, and a tower hanging lower end plate 102 is symmetrically arranged in the middle of the tower hanging vertical plate 101, and a tower hanging upper end plate 103 is symmetrically connected to the tail of the tower hanging vertical plate 101. The tower hanging vertical plate 101, the tower hanging lower end plate 102 and the tower hanging upper end plate 103 together constitute the tower end special-shaped hanging plate 100 in the special-shaped tension-resistant component, one end of which is connected to the insulator string 300 and the other end is connected to the iron tower in the power transmission equipment; further, refer to Figure 5 In order to make the tower end special-shaped hanging plate 100 in the present application be able to disperse stress better when in use, the present application sets an inclined surface at one end of the tower hanging vertical plate 101, and symmetrically cuts an inclined edge on one side of the tower hanging lower end plate 102 and the tower hanging upper end plate 103. The inclined surface and the inclined edge have the same function of dispersing stress. At the same time, the inclined surface on the tower hanging vertical plate 101 helps to improve the stress state of the tower end special-shaped hanging plate 100, disperse the tension, reduce local stress concentration, and thus reduce the risk of fracture. The tower hanging lower end plate 10 2 and the bevel on the upper end plate 103 of the tower hanging can improve the surrounding airflow conditions, reduce the generation of eddies, reduce wind resistance, and help improve the transmission efficiency of the line. At the same time, the bevel positions of the lower end plate 102 and the upper end plate 103 of the tower hanging in the present application are opposite, so that when the tower end special-shaped hanging plate 100 in this embodiment is in use, the tensions on both ends are parallel and balanced, so that the tower end special-shaped hanging plate 100 remains stable; the lower end plate 102 of the tower hanging is connected to the iron tower, and the upper end plate 103 of the tower hanging is connected to the insulator string 300.

[0034] Further, see Figure 4 In order to effectively stabilize the tower end special-shaped hanging plate 100, reduce the swing of the tower end special-shaped hanging plate 100 caused by wind vibration, and improve the stability of the line, in this application, a tower end hardware hanging hole 1021 is opened on the lower end plate 102 of the tower hanging near the hypotenuse, and the tower end hardware hanging hole 1021 is equipped with a tower end hardware 302, and a hanging ring hanging hole 1031 is opened on the tower hanging vertical plate 101 near the inclined surface and on the upper end plate 103 of the tower hanging near the hypotenuse. In this embodiment, since the hypotenuses opened on the lower end plate 102 and the upper end plate 103 of the tower hanging are relative, the opening The tower end hardware hanging hole 1021 on the tower hanging lower end plate 102 and the hanging ring hanging hole 1031 on the tower hanging upper end plate 103 are consistent in the width direction and parallel to each other. Therefore, the tower end hardware hanging hole 1021 is connected to the tower end hardware 302 by bolts, and then hung on the transmission tower through the tower end hardware 302, while the hanging ring hanging hole 1031 is connected to the insulator string 300 by bolts. The pulling force acting on the two ends of the tower end special-shaped hanging plate 100 is kept balanced, which can more effectively stabilize the tower end special-shaped hanging plate 100 and reduce the swing of the tower end special-shaped hanging plate 100 caused by wind vibration.

[0035] Figure 6 This is the second double-headed special-shaped high-strength tension-resistant component in this embodiment. The line end special-shaped hanging plate 200 in this embodiment includes a line hanging vertical plate 201, and the line hanging vertical plate 201 is symmetrically provided with a line hanging lower end plate 202 near the end position, and the line hanging vertical plate 201 is symmetrically connected to the line hanging upper end plate 203 near the tail. The line hanging vertical plate 201, the line hanging lower end plate 202 and the tower hanging upper end plate 103 together constitute the line end special-shaped hanging plate 200 in the special-shaped tension-resistant component, one end of which is connected to the insulator string 300 and the other end is connected to the cable in the power transmission equipment.

[0036] For further information, see Figure 7 In order to increase the mechanical strength and optimize the stress distribution, the present embodiment provides protrusions on both sides of the front end of the upper end plate 203 of the line hanger, and designs the lower end plate 202 of the line hanger as an isosceles trapezoidal structure as a whole. The protrusions can be used as an additional support point to improve the overall mechanical strength of the tension string, so that it can better withstand the tension of the cable and other external forces. Through the design of the protrusions, the force distribution of the cable on the tension string can be changed, so that the stress can be transmitted more evenly and the stress concentration phenomenon can be reduced. The isosceles trapezoidal structure of the lower end plate 202 of the line hanger has the same function as the beveled edges opened on the lower end plate 102 of the tower hanger and the upper end plate 103 of the tower hanger, which helps to improve the stress state of the special-shaped hanging plate 200 at the line end, disperse the tension, reduce local stress concentration, and thus reduce the risk of breakage.

[0037] Further, see Figure 8 In order to facilitate the connection between the special-shaped wire end hanging plate 200 and the power erection hardware in the prior art, in the present application, a corn bread hanging hole 2031 is opened on the protrusion on the wire hanging upper end plate 203 and the wire hanging vertical plate 201, and a wire end hardware hanging hole 2021 is opened at the vertex near the waist on the wire hanging lower end plate 202, and the wire end hardware hanging hole 2021 is equipped with a wire end hardware 304, and the special-shaped wire end hanging plate 200 is connected to the cable tension clamp through the wire end hardware 304, and the positions of the corn bread hanging hole 2031 on the wire hanging vertical plate 201 and the wire end hardware hanging hole 2021 are also designed with the same width and parallel to each other, and the purpose is also to play a stabilizing role.
