Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of insulators, in particular to an insulator with a wire clamp. Background Art
[0002] Advances in the power industry are placing higher demands on the reliability and ease of maintenance of transmission lines. As a key component in transmission lines, the performance of insulators is directly related to the stability and safety of power transmission. In existing transmission lines, insulators are often secured using traditional clamping or binding methods. These methods have numerous practical drawbacks, such as unstable fixation and susceptibility to environmental influences, leading to performance degradation.
[0003] To improve the stability and durability of insulators, researchers are currently experimenting with new materials and designs. Existing insulators are mostly made of ceramic and require separate wire clamps for installation. Ceramic materials are fragile and heavy, and the separate wire clamps required to work with the insulators increase installation complexity.
[0004] In the field of power transmission, the stability of insulators is crucial for ensuring the safe operation of power systems. Current insulator fixing methods generally have limitations. For example, simple fixing structures can easily cause cable displacement due to external forces, while overly complex fixing structures increase the difficulty of installation and maintenance. These limitations not only affect the stability of power systems but also increase operating costs. Utility Model Content

[0039] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0040] This embodiment relates to an insulator with a wire clamp, the overall structure of which is as follows: Figure 1 As shown, it includes a stud 1, a disc 3, a connecting column 4, a bottom clamp 5, and a top clamp 6.
[0041] Among them, the bottom of the stud 1 is inserted into the bracket, and the upper and lower ends of the stud 1 are respectively screwed with nuts 2. The lower end nut 2 fixes the stud 1 to the bracket, and the disc 3 and the connecting column 4 are inserted into the stud 1. The disc 3 and the connecting column 4 are arranged along the central axis of the stud 1. The bottom clamp 5 is inserted into the stud 1 and is located on the upper part of the connecting column 4. The top clamp 6 is slidably set on the stud 1. The cable is located between the bottom clamp 5 and the top clamp 6. The upper end nut 2 clamps the top clamp 6 and the bottom clamp 5 to the cable.
[0042] It is worth mentioning that the bracket is a bracket for supporting insulators installed on the tower. The bottom of the stud 1 is inserted into the through hole of the bracket. The stud 1 is fixed to the bracket by the nuts 2 screwed on the upper and lower ends of the bracket. The disc 3 and the connecting column 4 are fixedly installed on the stud 1. The stud 1 can be directly placed in the mold during production and directly molded on the stud 1. The function of the disc 3 and the connecting column 4 is to achieve electrical isolation and prevent current leakage. The disc of this embodiment adopts a flat surface to avoid water accumulation and dust adhesion, thereby affecting the isolation effect. The bottom clamp 5 can also be molded on the stud 1. Such a setting can avoid cumbersome installation. The cable is directly placed on the bottom clamp 5, and then the top clamp 6 is inserted on the stud 1. The top clamp 6 is pressed down by the upper nut 2 to achieve the top clamp 6 and the bottom clamp 5 clamping the cable.
[0043] Based on the above overall introduction, an exemplary structure of the insulator with a wire clamp in this embodiment is as follows: Figure 1 and Figure 2 As shown, at least two groups of discs 3 and connecting posts 4 are provided on the stud 1. The discs 3, connecting posts 4, bottom clips 5 and top clips 6 are all made of resin material, and the discs 3, connecting posts 4 and bottom clips 5 are integrally formed.
[0044] Specifically, different numbers of discs 3 can be used according to the current intensity, and the discs 3 are arranged on the stud 1. The more discs 3 and connecting columns 4 there are, the longer the creepage distance can be, thereby improving safety. The use of resin material can increase the insulation effect, and can also achieve high and low temperature resistance and corrosion resistance, thereby increasing the service life of the insulator. The purpose of using one-piece molding is to increase the strength of the insulator and also increase the service life.
[0045] As a preferred Figure 4 and Figure 5 As shown, the bottom clamp 5 of this embodiment is fixed with a protrusion 7 to prevent the top clamp 6 from rotating, and the top clamp 6 is provided with a groove 8 adapted to the protrusion 7. The protrusion 7 and the groove 8 are uniformly square, and both the protrusion 7 and the groove 8 are arranged at the stud 1.
[0046] Specifically, the setting of the protrusion 7 and the groove 8 ensures that the top clamp 6 can only be raised and lowered but not rotated, so as to avoid the top clamp 6 from rotating when clamping the cable, thereby affecting the quality of the cable. The size of the groove 8 is slightly larger than the size of the protrusion 7 to ensure convenient installation. The purpose of using a square shape is not only to facilitate the insertion of the top block into the groove 8, but also to facilitate the installation of the top block. It does not need to be aligned before insertion, thereby improving convenience.
[0047] As a preferred Figure 3 As shown, the bottom clamp 5 of this embodiment has a first cable groove 9 on one side of the stud 1 for placing cables, and the top clamp 6 has a second cable groove 10 opposite to the first cable groove 9. The second cable groove 10 is deeper than the first cable groove 9, and spherical grooves 12 are evenly distributed on the curved surfaces of the first and second cable grooves 9, 10 to prevent cables from sliding.
[0048] Specifically, the purpose of opening the first wire groove 9 and the second wire groove 10 is to ensure the adaptation of the cable, to avoid the flat surface from deforming the cable clamp, and to improve the clamping strength, and to prevent the cable from rotating between the top clamp 6 and the bottom clamp 5. The purpose of the second wire groove 10 being deeper than the first wire groove 9 is to ensure that the cable can be arranged along the axis of the second wire groove 10. When the nut 2 presses the top block down, the top block will not tilt, thereby avoiding the edge of the second wire groove 10 from pressing down on the cable. The setting of the spherical groove 12 can increase the lateral friction between the cable and the curved surface, and avoid sliding when the cable is pulled, thereby affecting the quality of the cable.
[0049] As a preferred Figure 4 and Figure 5 As shown, in this embodiment, strip grooves 13 are arranged on the first and second cable ducts 9, 10 to prevent cables from sliding. Building blocks 14 protruding from the top surface of the bottom clamp 5 are fixed on both sides of the first cable duct 9, and masonry grooves 15 for inserting the building blocks 14 are opened on both sides of the second cable duct 10.
[0050] Specifically, the strip groove 13 can also increase the friction between the cable and the curved surface. Cooperating with the spherical groove 12, it can prevent the cable from sliding between the top clamp 6 and the bottom clamp 5, thereby improving safety. The building block 14 and the first wire groove 9 are located on the same curved surface, and the building block 14 can be inserted into the building groove 15. This arrangement ensures that the connection between the first wire groove 9 and the second wire groove 10 is also a curved surface, thereby avoiding friction between this position and the cable, thereby affecting the quality of the cable.
[0051] The insulator with a wire clamp in this embodiment improves the fixing stability of the cable through the coordinated use of the stud 1 and the nut 2, and the clamping design of the bottom clamp 5 and the top clamp 6; the use of resin material and one-piece molding design reduces the weight of the insulator, improves corrosion resistance and production efficiency; the design of the protrusion 7 and the groove 8 prevents the rotation of the top clamp 6, ensuring more stable cable fixation; the design of the first wire groove 9 and the second wire groove 10, as well as the setting of the spherical groove 12 and the strip groove 13, effectively prevent the cable from sliding and improve the safety of the cable.
[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
