DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anticorrosive coating device for overhead transmission lines. More specifically, the present invention applies a new anticorrosion agent to an overhead transmission line that is already installed and has no anticorrosion agent applied thereto, or an already installed and anticorrosion agent is applied and the anticorrosion agent deteriorates. The present invention relates to an overhead transmission line anticorrosive agent application device capable of re-applying an anticorrosion agent to an existing overhead transmission line.

[0002]

2. Description of the Related Art Overhead transmission lines are used for transmitting power from a power plant or the like to an industrial area, a large city, or the like, and a steel core aluminum stranded wire is generally used. Here, a galvanized steel wire having excellent corrosion resistance is used as the steel core. Further, a pure aluminum wire or an aluminum alloy wire which is light and has high conductivity and excellent corrosion resistance is used as the aluminum wire twisted around the outer periphery of the galvanized steel core. However, even with this steel core aluminum stranded wire, there is a concern about corrosion in a strait crossing zone, a coastline zone, a heavy industrial zone, etc. where there is much salt, corrosive atmosphere gas, corrosive dust.

[0003] Therefore, in the case of a steel core aluminum stranded wire constructed in a cross-strait zone, a shoreline zone, a heavy industrial zone, etc. where there is a lot of salt, corrosive atmosphere gas and corrosive dust, a high-viscosity anticorrosive is applied to the surface and the inside of the stranded wire. It is supposed to. That is, by applying an anticorrosive agent to the surface of the galvanized steel wire and the aluminum wire, they are prevented from coming into contact with water, thereby preventing their corrosion.

[0004] The anticorrosive is composed of a grease-like substance mainly composed of mineral oil or synthetic oil.

[0005] Since a steel core aluminum stranded wire coated with an anticorrosive is installed between high steel towers and exposed to direct sunlight, wind and rain, dust, corrosive gas and the like, the anticorrosion coated with the anticorrosion agent after many months has passed. Troubles such as deterioration of the agent, dropping due to decrease in viscosity, and increase in water retention due to decrease in hydrophobicity occur.

Accordingly, in the case of a steel core aluminum stranded wire coated with an anticorrosive agent, the state of the applied anticorrosive agent is regularly inspected, and if the inspection result shows that the anticorrosive agent has deteriorated, the anticorrosive agent is applied again.

[0007]

However, the amount of the anticorrosive applied in the longitudinal direction of the steel core aluminum stranded wire coated with the anticorrosive applied between high steel towers, ie, each span, is several tens of kilograms. . For example, the cross-sectional area of a typical stranded conductor is 410 mm ²
When the steel core aluminum stranded wire of the above is laid over a 400 m diameter, the amount of the anticorrosive applied to the 400 m diameter becomes 30 kg or more. These anticorrosives will be supplied in containers to workers during construction between tall towers.

[0008] However, it is very difficult in terms of safety and technology to supply or move a container containing several tens of kilograms of an anticorrosive agent between tall towers. For this reason, the container with anticorrosive is placed under the anticorrosive-coated steel core aluminum stranded wire,
It moves with the movement of the work place. In this case, a high-viscosity anticorrosive is sent from the container with the anticorrosive applied to the steel core aluminum stranded wire that is placed under the installed anticorrosive agent coated steel core aluminum stranded wire to the erection position of the anticorrosive coated steel core aluminum stranded wire between high steel towers It is difficult with ordinary pumps.

Further, it is not easy to manually apply a new high-viscosity anticorrosive to a steel core aluminum stranded wire coated with an anticorrosive provided between high steel towers.

[0010] In addition, it is not preferable to apply a new anticorrosive to the deteriorated anticorrosive after a long time has passed since the installation, since the anticorrosive of the steel core aluminum stranded wire coated with anticorrosive has deteriorated. In other words, it is preferable to remove the deteriorated anticorrosive agent from the already installed anticorrosive agent-coated steel core aluminum stranded wire and then apply a new anticorrosive agent. However, it is more difficult to remove the deteriorated anticorrosive by mechanically rubbing the surface of the already installed anticorrosive coated steel core aluminum stranded wire with a brush or the like before applying a new anticorrosive.

The present invention has been made in view of such a point, and an object of the present invention is to solve the above-mentioned drawbacks of the prior art and to improve the efficiency of a steel core aluminum stranded wire installed between high steel towers. It is an object of the present invention to provide an overhead transmission line anticorrosive agent application device capable of applying a new anticorrosive agent efficiently and easily.
