7A to 7E are views sequentially showing a process of replacing a line fix unit using a processing power distribution facility that facilitates branching of an overhead distribution line to a transformer according to the present invention, and will be described with reference to this.

Referring to FIG. 7A, when the line fix unit 40 is to be replaced due to deterioration or damage, the electric leakage detection unit 80 installed in the wrought iron 20 is first checked.

For example, when a current flows through the wancheol 20 due to a short circuit, the earth leakage detection sensor 81 detects it, and the leakage detection sensor 81 immediately operates the lamp 82 to emit light to the surroundings. , The operator can intuitively recognize that a short circuit has occurred in the current Wancheol 20 through the light. Therefore, when a leakage current is detected, the operator can first resolve the leakage power supply and then proceed with the subsequent work.

After checking whether there is a short circuit as described above, the rope 62c of the first winder 62 constituting the windlass unit 60 is mounted through the upper pulley 61b, and then installed at the end of the rope 62c. The vise 62d is fixed to the overhead distribution line L.

When fixed by the first and second winders 62 and 62', respectively, as described above, the operator manipulates the electric motor 62a of the first winder 62 so that the rope 62c is wound around the drum 62b. At this time, as the rope 62c wound around the drum 62b pulls the vise 62d, the overhead distribution line L fixed to the vise 62d is pulled. Instead of releasing the tension, tension is applied to the rope 62c.

Referring to FIG. 7B, when the tension applied to the eye chain 41, the suspension insulator 42, and the human clamp 43 constituting the line fix unit 40 is released, the operator By separating the insulator cotter pin 43a connecting the clamp 43 to each other, the suspension insulator 42 and the human clamp 43 are separated from each other, and the eye clasp 41 is attached to the mounting bolt 33a of the advancing and retreating unit 30. ) And separated from Wancheol (20).

Referring to Figure 7c, as described above, when the eye clasp 41 and the suspension insulator 42 are separated from the wancheol 20 and the human clamp 43, respectively, the operator is the electric motor 62a of the second winder 62'. By operating the rope (62c) wound around the drum (62b) is released, and as the rope (62c) is unwound, the eye chain 41 and the suspension insulator 42 descend to the ground, and the worker on the ground The eye clasp 41 and the suspension insulator 42 are tied to the rope 62c, and on the telephone pole 10, the operator remanufactured the electric motor 62a of the second winding machine 62' to wind the rope 62c. It pulls up the eye chain (41) and the suspension insulator (42). When the new eye clasp 41 and the suspension insulator 42 are pulled up as described above, the eye clasp 41 is inserted into the mounting bolt 33a of the advancing and retreating unit 30, and the eye clasp 41 is attached to the mounting bolt ( Fill the nut (23b) to the mounting bolt (33a) so that it does not come off from 33a).

Referring to FIG. 7D, when the eye clasp 41 is connected to the wancheol 20, the suspension insulator 42 and the human clamp 43 may be interconnected. The overhead distribution line L is connected to the first winding machine 62 Even if it is firmly fixed while pulling by using, a slight sag occurs at the initial position, and as a result, a distance (D) is created between the suspension insulator 42 and the human clamp 43 by a certain distance, and a hole (Fig. 3), it is not easy to interconnect using an insulator cotter pin 43a.

Referring to Figure 7e, in the case of spaced apart (D) by a certain distance in this way, the operator can solve this by using the advance and retreat unit 30. First, when the operator manipulates the motor 32, the motor 32 The transfer screw 31 is rotated, and the transfer block 33 is moved by the rotation of the transfer screw 31, and the transfer block 33 moves to the mounting bolts 33a and 33a. The connected eye clasp 41 moves along a long hole (13: see FIG. 2), and accordingly, a hole formed at the end of the suspension insulator 42 (see FIG. 3) and a hole formed at the end of the human clamp 43 ( 3) can be quickly adjusted. When the hole of the suspension insulator 42 and the hole of the human clamp 43 match as described above, the insulator cotter pin 43a is inserted into the matched hole and then fixed with a split pin P', and finally, the first winding machine The first winder 62 is operated and controlled so that the tension on the rope 62c of the 62 is applied to the line fix unit 40 to release the rope 62c, and a vise 62d from the overhead distribution line L Separate the.

According to this embodiment, the branch unit 70 and the branch line L'can be used to easily and conveniently branch the branch from the jumper line J to the transformer 11, which is useful.

In addition, since the electric leakage detection unit 80 senses the electric current flow through the wancheol 20 and emits light to the surroundings, the operator can intuitively determine whether there is a electric leakage, and accordingly, the operator from the risk such as an electric shock accident There is an advantage that can provide safe protection.
