Abstract

PROBLEM TO BE SOLVED: To provide a repairing cover, whereby the through-holes and damaged places of the insulator of a power distribution cable can be repaired using indirect hot-line tools and robots. SOLUTION: In a repairing cover, on one side portion of halved cylindrical bodies 3, 3' having tapers 1 at both their ends and coupled to each other by a thin-walled rubber or plastic band 2 and made of rubber or plastics, a fin 5 with fastening protrusions 4 is provided, and on the other side thereof, a fin 7 wit holes 6 for fitting the fastening protrusions 4 therein is provided, and further, at one end of one of the fins 5, 7, a fin 10 with a neck portion 9 is provided. As the repairing cover for robots, at the both ends of the fins 5, 7, somewhat longish fins with nearly equal thicknesses to the radius of the halved cylindrical bodies 3, 3' are further provided.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulation formed when a current-carrying insulated wire or cable is pierced with a needle electrode or the like in order to form a bypass circuit at the time of uninterruptible work on a distribution line such as 6600 volts. A repair cover used to repair damaged parts of the insulator caused by contact with through holes in the body or trees, etc. More specifically, repairs designed to be repaired by robots and indirect hot-line tools It relates to the structure of the cover.

[0002]

2. Description of the Related Art Conventionally, repair of the above-mentioned through holes and damaged parts has
Workers on the insulation bucket approached the through-holes and damaged parts, wore insulating gloves, and repaired the through-holes and damaged parts directly with hands using insulation cover and taping. There is a danger, and the development of a repair cover that can be repaired by the indirect hot-line method using tools and robots has been strongly desired.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to achieve the long-awaited desire described in the prior art. The purpose of the present invention is to provide a repair cover capable of repairing.

[0004]

SUMMARY OF THE INVENTION A repair cover according to the present invention is provided.
Is provided with a fin having a taper on both ends, a half-cylindrical cylindrical body made of rubber or plastic connected by a thin rubber or plastic band, and having a locking projection on one side, and A fin having a hole into which a locking projection is fitted is provided on a side of the fin, a divided projection extending inward inside the base of the taper, and a fin having a constricted portion at one end of the fin. Is provided.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present invention, as shown in FIGS. 1, 2 and 3, tapes 1 are provided at both ends and a thin rubber or tape is used. A locking projection 4 is provided on one side of a half-cylindrical cylindrical body 3, 3 'made of rubber or plastic connected by a plastic strip 2.
A fin 7 having a hole 6 into which the locking projection 4 is fitted, and a divided projection 8 extending inward inside the base of the taper 1; Fin 10 having constriction 9 at one end of fin 5 or fin 7
Is provided.

The fins 5 and 7 are finished in a size that can be easily grasped by the above-mentioned yatco.
The constricted portion 9 is finished in such a size that it can be easily peeled off with a yoke after the repair cover is attached. The divided projections 8 serve as weirs for preventing the flexible insulating mixture 13 filling the cylindrical portions of the half-cylindrical cylinders 3 and 3 'from flowing out to the outside, and are provided with a repair cover. In this state, it is bent and in contact with the surface of the insulator of the electric wire or cable. Note that a hook is provided at the tip of the projection 4 so as not to easily come off.

For robots, FIGS. 4 and 5
As shown in the figure, slightly longer fins 11 and fins 12 are provided at both ends of the fins 5 and 7 with a thickness substantially equal to the radius of the half-shaped cylindrical bodies 3 and 3 '. 12
Is provided with a fin 10 having a constricted portion 9 at one end. When the fin 11 is fitted to the fin 12, as shown in FIG. 5, it is preferable that the outer diameter of the fin is approximately equal to the outer diameter of the repair cover. To locally press the insulator,
It is not preferable because the insulator may be damaged.

A flexible insulating mixture 1 mainly composed of butyl rubber or the like is provided on the cylindrical portions of the half-cylindrical cylindrical bodies 3 and 3 '.
3 and its surface is covered with oil paper or the like. At the time of use, oil paper and the like are removed. Note that the repair cover
Are manufactured collectively by an injection molding machine or the like except for the insulating mixture 13.

[0009]

Since the present invention is configured as described above, it has the following effects. There is no danger of electric shock because damaged parts of the insulator can be repaired using indirect hot-line tools or robots. Thick and long fins are provided, so even if a robot is used, the insulators of electric wires and cables will not be damaged.
Repair work is possible. Since the insulating mixture having flexibility fills the through-holes of the insulator, intrusion of rainwater or the like is prevented, and generation of water birds and corrosion of the conductor are reliably prevented. It can be mass-produced with an injection molding machine at low cost.
