Description

Technical Field

[0001] The invention relates to the technical field of high-voltage power transmission, in particular to a honeycomb supporting insulator for a high-voltage power transmission line. Background Art

[0002] Most of the insulators in the power system directly exposed to the environment are still porcelain and glass insulators. This type of insulator has a history of more than 100 years. Operating experience shows that this material is resistant to environmental aging, so it is the most widely used. However, it also has the disadvantages of being large, bulky and heavy, fragile during loading and unloading, transportation and external force damage, and prone to flashover under dirty conditions; this will damage the reliability of the system.

[0003] Traditional disc or cone insulators have certain limitations, especially in steady-state operation under high voltage or impulse lightning conditions, where breakdown is more likely to occur. In addition, the structure of such insulators is complex, requiring the use of multiple materials, and the manufacturing cost is high. In addition, the closed shape is not conducive to the circulation and evacuation of gas inside the insulator, affecting the efficiency of gas insulation. In addition, when a cylindrical isolator fails, arc products or contaminants are likely to migrate along the disc or cone leakage path, causing the accumulation of subsequent faults. The large surface area of ​​the disc or cone spacer will limit the path and evacuation of the gas flow, affecting the free flow and cleanliness of the gas. Summary of the invention

[0022] In order to make the above-mentioned objects, 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.

[0023] 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.

[0024] 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 necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1, reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a honeycomb support insulator for a high-voltage transmission line, which includes a bearing assembly 100, including a support bus 101 and a first filler 101a disposed inside the support bus 101; and,

[0026] The filling assembly 200 includes an insulator 201 disposed outside the supporting busbar 101 .

[0027] Usage process: One edge of the outer insulator 201 is tightly fitted with the inner diameter of the load-bearing shell 102, which effectively ensures the stable placement of the supporting busbar 101 in the load-bearing shell 102, and at the same time achieves excellent electrical insulation effect. Such a design makes the electric field distribution more uniform, greatly reduces the electric field concentration phenomenon, thereby improving the dielectric properties of the insulator and extending the tracking distance.

[0028] Example 2, reference Figures 1 to 3 , which is the second embodiment of the present invention, provides a honeycomb support insulator for a high voltage transmission line, specifically, it includes a bearing assembly 100 and a bearing shell 102 arranged outside the insulator 201, and a second filler 102a is arranged inside the bearing shell 102. The material of the bearing shell 102 is epoxy resin.

[0029] The support busbar 101 and the bearing shell 102 are filled with a high dielectric gas, which is sulfur hexafluoride. The support busbar 101 is made of steel. An installation channel is provided inside the support busbar 101. The diameter of the bearing shell 102 is 10 cm, and the diameter of the support busbar 101 is 3 cm.

[0030] Usage process: The central area of ​​the insulator is used as the supporting area of ​​the supporting busbar 101, and it extends outward from the center in a regular manner to present a plurality of insulator 201 units. When the transmission line is in operation, the supporting busbar 101 smoothly passes through the central area of ​​the insulator and is firmly supported at the central position by the honeycomb structure, thereby effectively ensuring the stable placement of the supporting busbar 101 in the bearing shell 102, while achieving excellent electrical insulation effect.

[0031] Example 3, reference Figures 1 to 3 , which is the third embodiment of the present invention, and this embodiment provides a honeycomb support insulator for a high-voltage transmission line. Specifically, it includes a filling component 200 and also includes a connecting filler 201a arranged on the outside of the insulator 201, a connecting piece 202 is provided on the outside of the connecting filler 201a, and a supporting piece 203 is provided at the other end of the connecting filler 201a.

[0032] The insulator 201 is filled between the supporting busbar 101 and the load-bearing housing 102 .

[0033] The insulator 201 has a hexagonal cross section.

[0034] The insulator 201 , the bearing shell 102 and the two connecting fillers 201 a have correspondingly increased combined curvature radii, making the structure more stable and reliable.

[0035] Among them, the insulator 201 is set to a honeycomb structure, and its uniform distribution characteristics help to improve the dielectric stress distribution and reduce the electric field concentration. The arrangement of the insulator 201 units makes the electric field more evenly distributed inside the insulator, thereby improving the voltage resistance and service life of the insulator. The insulator is manufactured using materials with high dielectric properties to ensure that it has good insulation performance under high voltage environments. At the same time, the injection molding process is used to ensure the size and shape accuracy of the insulator 201 units.

[0036] Usage process: The insulator 201 adopts a honeycomb structure and is composed of multiple insulator 201 units. This structure has high stability and mechanical strength and can effectively support the center conductor. The honeycomb structure provides more gas channels, allowing the gas to circulate more smoothly inside the insulator, thereby improving the insulation performance and heat dissipation effect. Compared with the traditional triangular structure, the honeycomb shape increases the contact area between the gas and the insulator surface, which is beneficial to the circulation and heat dissipation of the gas.

[0037] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangement, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present invention. The order or sequence of any process or method steps can be changed or reordered according to alternative embodiments.

Therefore, the invention is not limited to a specific embodiment, but extends to numerous modifications still falling within the scope of the appended claims.

[0038] Additionally, in order to provide a concise description of exemplary embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
