Description

Technical Field

[0001] This utility model relates to an anti-corrosion structure for the down conductor of a power transmission line grounding grid, specifically an anti-corrosion structure for the down conductor of a power transmission line grounding grid, belonging to the technical field of power transmission line grounding grids. Background Technology

[0002] The transmission line grounding grid, also known as the grounding grid, is a facility in the power system used to connect transmission lines, substations and the earth. Its main function is to divert fault current or lightning current from electrical equipment into the ground, thereby protecting the safety of equipment and personnel. When using the transmission line grounding grid, underground leads are used in conjunction with it.

[0003] Some existing transmission lines have down conductors that connect directly to the ground grid vertically underground. Because these down conductors are not designed with anti-corrosion structures, they will rust or corrode over time due to changes in weather conditions. This increases their resistance, affecting current transmission efficiency. At the same time, corrosion weakens their mechanical strength, making them more susceptible to breakage under external forces such as wind and ice loads. This dual decline in electrical performance and structural strength directly threatens the stable operation and safety of the power system.

[0004] Therefore, a corrosion-resistant structure for the down conductor of the power transmission line grounding grid is proposed. Utility Model Content

[0005] This utility model proposes a rust-proof structure for the down conductor of a power transmission line grounding grid to solve the problems of corrosion and rust in the prior art.

[0006] This utility model is achieved through the following technical solution: a rust-proof structure for the down conductor of a power transmission line grounding grid, comprising a conductor body, wherein a first segmentation mechanism and a second segmentation mechanism are respectively provided on the outer side of the conductor body; The first segmentation mechanism includes a first connector. Two sets of first V-shaped plates are fixedly installed on the outer surface of the first connector. A first rotating column is rotatably connected to one side of each set of first V-shaped plates that are close to each other. A first connecting plate is fixedly installed on the outer surface of each set of first rotating columns. A first connecting column is fixedly installed on one side of each set of first connecting plates that are close to each other. A first reinforcing ring and a second reinforcing ring are fixedly installed on one side of each set of first connecting columns that are close to each other. The second segmentation mechanism includes a second connector. Two sets of second V-shaped plates are fixedly installed on the outer surface of the second connector. The two sets of second V-shaped plates are rotatably connected to a second rotating column on their respective sides that are close to each other. A second connecting plate is fixedly installed on the outer surface of each set of second rotating columns. A second connecting column is fixedly installed on the respective sides of each set of second connecting plates that are close to each other. A third reinforcing ring and a fourth reinforcing ring are fixedly installed on the respective sides of each set of second connecting columns that are close to each other. A protective component is provided on the outer side of the line.

[0007] The protective component includes a rust-proof sleeve, the wire is located inside the rust-proof sleeve, and there are three wires. The inner wall of the first connector and the interior of the second connector are both provided with a rust-proof coating. The upper surface of the first connector and the upper surface of the second connector are both provided with two drainage holes.

[0008] The first and second reinforcing rings are engaged on their adjacent sides by a snap-fit ​​device and a snap-fit ​​hole, and the third and fourth reinforcing rings are engaged on their adjacent sides by a snap-fit ​​device and a snap-fit ​​hole.

[0009] The outer surface of the line is connected to the first connector and the second connector respectively, and the first connector and the second connector are both made of corrosion-resistant alloy.

[0010] Each set of first connecting posts has a first fastening ring fixedly installed on its outer surface. The side of each set of first fastening rings that is far apart from each other is fixedly connected to the side of each set of first connecting plates that is close to each other.

The side of each group of second fastening rings that is far apart from each other is fixedly connected to the side of each group of second connecting plates that is close to each other.

[0012] This utility model provides a rust-proof structure for the down conductor of a power transmission line grounding grid, which has the following beneficial effects: By setting up a first segmentation mechanism and a second segmentation mechanism, the segmented connection of the line is realized, effectively avoiding the problems of increased resistance and decreased mechanical strength caused by surface rust or corrosion after long-term use in traditional integral structures. A first V-shaped plate, a first rotating column, a second V-shaped plate, and a second rotating column are respectively fixedly installed on the outer surfaces of the first and second connectors, allowing the first and second connectors to flexibly adapt to the bending and displacement of the down conductor. At the same time, the connecting plates and connecting columns enhance the stability and firmness of the connection, effectively preventing breakage caused by external forces. The rust-proof sleeve further protects the line. Completely enclosed, the conductor is isolated from direct contact with the external corrosive environment, greatly extending its service life. Furthermore, the anti-rust coating on the inner walls of the first and second connectors further enhances the anti-rust effect, ensuring good electrical performance even under harsh weather conditions. The drainage hole design effectively drains accumulated water, avoiding corrosion problems caused by moisture retention. In summary, this design significantly improves the anti-rust capability of the down conductor, ensures current transmission efficiency, and enhances mechanical strength, thereby greatly improving the stable operation and safety of the power system, resulting in significant economic and social benefits.

[0017] Please refer to this carefully. Figure 1 and Figure 3The outer side of the production line 1 is provided with a protective component 2, which includes a rust-proof sleeve 201.
