Description

Technical Field

[0001] This utility model relates to a suspended insulator. Background Technology

[0002] Suspension insulators are key components in power systems used to suspend cables and ensure electrical insulation, and are widely used in high-voltage transmission lines, substations, and other applications. Insulators typically consist of an insulator body, a steel cap, and steel feet. Both the steel cap and feet have structures for connecting suspension insulators in series. When using suspension insulators in series, the steel cap of one insulator is connected to the steel foot of the next insulator. When existing suspension insulators are connected in series to suspend conductors, the weight of the multiple insulators and the weight of the cable create a tensile force acting on the insulator. The stronger the connection between the steel cap and the insulator body, the better the insulator's ability to withstand this tensile force, and the stronger its load-bearing capacity when suspending cables. Therefore, developing a suspension insulator with a strong connection between the steel cap and the insulator body is of significant practical importance. Summary of the Invention

[0003] The purpose of this invention is to provide a suspended insulator to solve the problems mentioned in the background art.

The connecting part is disposed on the inner side of the insulator body. Multiple raised rings are evenly spaced on the side wall of the connecting part. A filling layer is provided between the connecting part and the inner wall of the iron cap. The skirt part is disposed at the bottom of the connecting part. A threaded cylinder is provided at the bottom of the skirt part. A steel foot assembly is provided on the threaded cylinder. Two anti-fall-off components are provided at the bottom of the iron cap. The anti-fall-off components include an arc-shaped plate one and an arc-shaped plate two. The arc-shaped plate one is disposed close to the side wall of the iron cap. The arc-shaped plate two is disposed at the bottom of the arc-shaped plate one. The arc-shaped plate one and the arc-shaped plate two are an integral structure. Fastening bolt one and fastening bolt two are connected between the arc-shaped plate one and the side wall of the insulator body. The fastening bolt two is disposed below the fastening bolt one.

[0018] See Figures 1 to 5 The suspended insulator shown includes an insulator 11 and an iron cap 12. The iron cap 12 is disposed on the top of the insulator 11. The insulator 11 includes a connecting part 22 and a skirt part 24. The connecting part 22 is disposed on the inner side of the insulator 11. A plurality of raised rings 23 are evenly spaced on the side wall of the connecting part 22. A filling layer 13 is provided between the connecting part 22 and the inner wall of the iron cap 12. The filling layer 13 is silicate cement. The filling layer 13 fills the space between the connecting part 22 and the inner wall of the iron cap 12, utilizing the curing adhesive of the filling layer 13. The working mechanism secures the iron cap 12 to the connecting part 22. The inner wall of the iron cap 12 is roughened by sandblasting, thereby enhancing the adhesion strength between the filling layer 13 and the inner wall of the iron cap 12. The solidified filling layer 13 is wedged into the gaps between the various protruding rings 23, making the filling layer 13 and the connecting part 22 bond more firmly. The umbrella skirt part 24 is located at the bottom of the connecting part 22, and the bottom of the umbrella skirt part 24 is provided with a threaded cylinder 28. The threaded cylinder 28 is provided with a steel foot assembly 17. The bottom of the iron cap 12 is provided with two anti-detachment components 14. The anti-fall-off component 14 includes an arc-shaped plate 20 and an arc-shaped plate 21. The arc-shaped plate 20 is set close to the side wall of the iron cap 12, and the arc-shaped plate 21 is set at the bottom of the arc-shaped plate 20. The arc-shaped plate 20 and the arc-shaped plate 21 are an integrated structure. A fastening bolt 18 and a fastening bolt 19 connect the arc-shaped plate 20 to the side wall of the insulator 11. The fastening bolt 19 is located below the fastening bolt 18. The two arc-shaped plates 20 are joined together to form a cylindrical structure that is close to the side wall of the iron cap 12. The two arc-shaped plates 21 are joined together to form a ring structure. The connecting part 22 passes through the central hole of the ring structure. The ring structure formed by the two arc-shaped plates 21 forms a certain shield at the opening at the bottom of the iron cap 12, thereby blocking the filling layer 13 inside the iron cap 12 and preventing the filling layer 13 from being subjected to excessive tension and detaching from the iron cap 12 as a whole. This strengthens the connection between the iron cap 12 and the connecting part 22, which also strengthens the connection between the insulator 11 and the iron cap 12, thereby improving the load capacity of the suspended insulator when suspending the cable.

[0019] Furthermore, the bottom of the umbrella skirt 24 is provided with annular umbrella ridge 1 25, annular umbrella ridge 26, and annular umbrella ridge 3 27. The diameters of the annular umbrella ridge 1 25, annular umbrella ridge 26, and annular umbrella ridge 3 27 decrease sequentially. The edge of the umbrella skirt 24 and the annular umbrella ridge 1 25, annular umbrella ridge 26, and annular umbrella ridge 3 27 are concentric circles. The threaded cylinder 28 is located at the center of the concentric circles. The umbrella skirt 24, annular umbrella ridge 1 25, annular umbrella ridge 26, and annular umbrella ridge 3 27 can extend the creepage distance on the surface of the insulator, effectively preventing flashover accidents caused by surface leakage in humid, dirty, or salt spray environments.

[0020] Furthermore, the connecting part 22, the protruding ring 23, the umbrella skirt part 24, the annular umbrella ridge one 25, the annular umbrella ridge two 26, the annular umbrella ridge three 27 and the threaded cylinder 28 are integrated structures, and the entire insulator 11 is integrally formed by mold casting.

[0021] Furthermore, the steel foot assembly 17 includes a steel column 29 and a hanging ring 30. The upper surface of the steel column 29 is provided with threads, and the steel column 29 is threadedly connected to the threaded cylinder 28. The hanging ring 30 is fixed to the lower end of the steel column 29.

[0022] Furthermore, a mounting plate 15 is fixedly installed on the top of the iron cap 12. There are two mounting plates 15, each with a mounting hole 16. A certain gap is left between the two mounting plates 15. When connecting the suspended insulators in series, the hanging ring 30 of one insulator is placed between the two mounting plates 15 of the next insulator, so that the center hole of the hanging ring 30 is aligned with the mounting hole 16 on the mounting plate 15. Then, a pin is installed between the mounting plate 15 and the hanging ring 30 to complete the connection of the two insulators in series.

[0023] The working principle of this utility model is as follows: two anti-detachment components 14 are provided at the bottom of the iron cap 12. The arc-shaped plates 20 of the two anti-detachment components 14 are spliced ​​together to form a cylindrical structure that fits tightly against the side wall of the iron cap 12. Fastening bolts 18 and 19 fix the arc-shaped plates 20 to the iron cap 12, so that the anti-detachment components 14 are stably installed on the iron cap 12. The arc-shaped plates 21 of the two anti-detachment components 14 are spliced ​​together to form a ring structure. This ring structure forms a certain shield at the opening at the bottom of the iron cap 12, thereby blocking the filling layer 13 inside the iron cap 12 and preventing the filling layer 13 from being subjected to excessive tension and detaching from the iron cap 12 as a whole. This strengthens the connection between the iron cap 12 and the connecting part 22, that is, strengthens the connection between the insulator 11 and the iron cap 12, thereby improving the load capacity of the suspended insulator when suspending cables.

[0024] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
