Description

[0001] The present invention relates to a connection structure of an overhead electric power line,

[0001] The present invention relates to a distributing type working wire connection structure of a pole of a pole in a distribution technology field, and more particularly, to a structure for preventing a disconnection due to wind power while sufficiently supporting a jumper wire, So that the check and replacement of the pivot rotary tool can be performed quickly.

Generally, a large power generated in a power plant is transmitted to each substation with high-voltage power through a power transmission line such as a power transmission tower, and then transformed at various stages in a substation, and a cable is used for use in a consumer of each home or building It is a well-known fact that they are subjected to a distribution process which is supplied to each region.

At this time, the electric power supply to the general customer is supplied through the electric pole installed at regular intervals, and the connection of the working electric wires in each electric pole is connected by using the jumper wire which is laid down below the full iron.

This conventional wire connection has a problem that frequent breakdown of the wire is caused due to contact with the electric pole due to wind pressure.

In order to solve such a problem, insulators for fixing the jumper wires are installed in the bar coils. However, when insulators for fixing the jumper wires are installed in the bar coils, they can not sufficiently absorb the wind force when the wind power is generated. There is a problem that the jumper wire is disconnected because the stress is concentrated.

As a conventional technique which partially improves such a problem, Korean Patent Registration No. 10-0861795 (Oct. 10, 2008) discloses a " electric distribution processing wire connection structure of Jeonju. &Quot;

However, such a conventional electric distribution type working wire connection structure of the electric pole can not easily confirm the lighting state of the indicator lamp, so that it is difficult to inspect and replace the pivot rotary spindle quickly, resulting in a safety accident.

[ At this time, the fastening member B is an elongated bolt and is screwed to the case 10 and the case F through the case 10 so that the case 10 and the case F are fastened together Mutually fixed. The inside of the case 10 is partitioned into a cylinder mounting portion 12 and a first spring mounting portion 13 by a fixing plate 11 formed in a horizontal direction.

The fixing plate (11) is formed with a seating hole (h) passing through the center of the fixing plate (11). When the lower surface of the pivot rotary tool 20 is inserted into the seating hole h, the pivot rotary tool 20 and the seating hole h are positioned at the maximum face So that the fixing plate 11 can stably support the pivotal rotary shaft 20.

The pivot rotary tool 20 has a spherical shape and has a through hole 21 penetrating vertically so that the lower surface of the pivot rotary shaft 20 is seated in the seating hole h of the case 10 and the upper surface thereof is fixed to the cylinder mounting portion 12 Exposed, and rotated in all directions.

At this time, the through hole 21 has a fastening portion 21a screwed to the upper end of the insulator body 30, and a wire fixing portion 21b communicated with the fastening portion 21a is fastened to the fastening portion 21a.

The insulator main body 30 is made of an insulating material, and a pivot rotating tool 20 is screwed to the upper end and a securing mechanism 40 is screwed to the lower end.
