Description

【発明の詳細な説明】 本発明は架空送電線延線時の送電線等の保護法に係る。[Detailed description of the invention] The present invention relates to a method for protecting power transmission lines, etc. when extending overhead power transmission lines.

When extending a new power transmission line onto a track with an existing live line, as a measure against guidance from the existing live line, the power line to be extended is passed through a grounding roller before being extended.

Therefore, the electric wire and the grounding roller may come into incomplete contact at a portion near the end of the electric wire clamp protector, joint protector, etc., and an arc may occur. This arc causes arc marks on the wire, which may reduce the performance of the wire.

In the present invention, the above object is achieved by applying a protective layer to the power transmission line or the like using a conductive material such as a braided wire or stainless steel braced tape at a portion where incomplete contact with the grounding roller is likely to occur.

以下、実施例につき本発明の詳細な説明する。Hereinafter, the present invention will be described in detail with reference to Examples.

In FIG. 1, a conductive protective layer 3 is formed by wrapping stainless steel preformed tape around a portion of a power transmission line 1 near a clamp protector 2 attached to a clamp. When the wire is extended past the ground roller, the portion of the wire 1 near the clamp protector 2 may come into incomplete contact with the ground roller, causing arc marks at that portion, but in the present invention, Since the conductive protective layer 3 is provided in that portion, it is the protective layer that causes arc marks due to incomplete contact, and the wire surface is not damaged at all. Therefore, the performance of the wire does not deteriorate.

なお、延線完了後、保護層3を除去する。Note that after the wire stretching is completed, the protective layer 3 is removed.

FIG. 2 shows an embodiment in which the present invention is applied to a wire rope connection. A conductive protective layer 6 is formed by winding a braided wire near the connecting eye 5 at the connecting end of the wire rope 4 . In this embodiment as well, the surface of the wire rope 4 is protected in the same manner as in the previous embodiment, and there is no risk that the wire rope 4 will be weakened.
