Abstract

The present invention relates to a structure of a distribution line apparatus for improving stability in distribution. The distribution line apparatus can certainly prevent an electric shock accident even if a pedestrian is in contact with a lead distribution cable by shielding the lead distribution cable, which is connected to an overhead distribution line and entering under the ground along an electric pole, with a cover body including a first cover portion, a second cover portion, a lead distribution cable support portion, and first and second catching pieces, and a lead distribution cable support cover including a fastening unit to fasten the first cover portion and the second cover portion. The cover body and the fastening unit are continuously molded by compression molding and so the cover body and the fastening unit are easily cut and produced into a desired length. The fastening unit can be slid into the first and second catching pieces and so the fastening unit can be easily fastened without any other tools. The distribution line apparatus pulls the overhead distribution line when the overhead distribution line stretches and droops downwards, and pushes the overhead distribution line when the overhead distribution line shrinks and tense therein increases, thereby allowing the overhead distribution line to be stably supported by a crossarm and an insulator. Components of the distribution line apparatus including a driving motor and a driving screw, which prevent the overhead distribution line from drooping or being tensed, are arranged restrictedly at a free end portion of the crossarm and the distribution line apparatus includes a dust cover to protect the driving screw. Therefore, it possible to prevent the components from being contaminated by rainwater, snow, dust, etc. and prevent malfunction or a breakdown by fundamentally ruling out the possibility that birds such as a magpie nest with ease. Accordingly, the stability in power distribution may be improved.

When the wires are stretched, they are sagged downward. When they are contracted, the tension increases, and the crowns 20a and 20b are stretched. And the supporting state by the insulators 70a and 70b may become unstable.

In order to cope with this, the present invention includes a temperature sensor 90 and a control unit 100. In the present invention, the temperature in summer is raised to such an extent that the processing power distribution lines L1 and L2 are extended. When the temperature sensor 90 detects The controller 100 outputs a reverse rotation command in response to the temperature sensing signal transmitted from the temperature sensor 90 and the driving motor 40 rotates in the reverse direction.

When the drive motor 40 is rotated in the reverse direction, the left drive screw 50a is driven by the right screw action of the left drive screw 50a screwed to the left internal threaded portion 43a formed on the left side of the inner peripheral surface of the rotary shaft 42, And the right drive screw 50b threadedly engaged with the right internal thread portion 43b formed as a left-hand thread on the right side of the inner circumferential surface of the rotary shaft 42. The right drive screw 50b, The right drive screw 50b moves to the left side in the figure and pulls the insulator 70b and the processing power distribution line L2.

This allows the elongated machining distribution lines L1 and L2 to be stably supported by the crows 20a and 20b and the insulators 70a and 70b without being laid down.

When the temperature of the power distribution lines L1 and L2 is lowered in the winter so that the temperature of the power distribution lines L1 and L2 is lowered in the winter, the temperature sensor 90 senses the temperature and outputs a temperature sensing signal. And outputs the forward rotation output in accordance with the received temperature detection signal, and the drive motor 40 is rotated forward.

When the drive motor 40 is rotated in the forward direction, the left drive screw 50a is rotated by the right screw action of the left drive screw 50a screwed to the left internal threaded portion 43a formed by the right screw on the left side of the inner peripheral surface of the rotary shaft 42 The right threaded portion 43b formed on the right side of the inner circumferential surface of the rotating shaft 42 by the left screw thread and the left screw of the right driving screw 50b threadedly engaged with the threaded portion 70a and the processing power distribution line L1, The right drive screw 50b moves rightward in the drawing to push the insulator 70b and the processing power distribution line L2.

This makes it possible to maintain a state in which the contracted power distribution lines L1 and L2 are stably supported by the crows 20a and 20b and the insulators 70a and 70b without being strained.

The driving motor 40 and the driving screws 50a and 50b are arranged in a limited manner at the free ends of the bars 20a and 20b so as to prevent the processing power distribution lines L1 and L2 from being sagged or tensed Therefore, it is possible to prevent these components from being contaminated by rain, snow and dust, and to prevent malfunctions or malfunctions by eliminating elements such as black maggots that can easily nest the nest.

Dust covers 110a and 110b for protecting the driving screws 50a and 50b are inserted between the opposite ends of the drive motor 40 and the opposed faces of the wrought iron pieces 20a and 20b, The dust covers 120a and 120b for protecting the drive screws 50a and 50b are inserted between the opposite surfaces of the insulators 70a and 70b so that the drive screws 50a and 50b are contaminated by rainwater, It is possible to prevent a malfunction or inoperability.

According to the structure of the distribution line apparatus improved in the stability of power distribution according to the present invention, the stability of power distribution can be improved by the above-described operation.
