The lightning arrester (6), the ground wire (7), and the ground wire insulator (8) are the same as those previously known, and in the present invention, the ground wire insulator (8) is fixed to the Gyeongwangeum (3) through the adapter (20).

The shackle (10) has the function of supporting the distribution line (1) by fixing the distribution line insulator (4) to the light fixture (3) and the function of supporting the adapter (20) to fix the related components of the lightning arrester (6). It includes a shackle body 11 to which the distribution line insulator 4 is connected while being fixed to the Gyeongwangeum 3 in accordance with its function, and an adapter fixing rod 12 protruding from the upper part of the shackle body 11.

For example, the shackle body 11 has a structure in which both the left and right sides and the rear are open, that is, a channel composed of a front part and an upper and lower horizontal part extending in parallel to the upper and lower parts of the front part, respectively, and the front and upper and lower surfaces of the gyeongwangeum 3. It is fixed through a fastener (13) while surrounding the . The fastener 13 is a bolt to which a nut is fastened after penetrating the upper horizontal part, the Gyeongwangeum 3, and the lower horizontal part.

The shackle body 11 includes a protrusion on the front part that secures the distribution line insulator 4.

The adapter fixing rod 12 is erected on the upper surface of the upper horizontal portion of the shackle body 11 and is inserted into the hole formed in the adapter 20 to fix the adapter 20.

The adapter fixing rod 12 may include a thread on the outer peripheral surface so that a nut can be fastened to the upper part penetrating the hole of the adapter 20.

Insert the adapter fixing rod (12) of (10), rotate the adapter (20), insert the adapter body (21) into the Gyeongwangeum (3), and then assemble it by fixing it with the fastener (23).

According to the overhead distribution line fixing device having a lightning protection function configured as described above, the adapter 20, which fixes the ground wire insulator 7 to the light wangeum 3, is connected to the shackle 10 to connect the adapter 20 and the ground wire insulator 7. By expanding the support base, the shaking of the ground wire insulator 7 is reduced, and in particular, even if the fastener 23 is weak, the ground wire insulator 7 is stably supported through fixation with the shackle 10.

Meanwhile, the present invention may include an auxiliary lightning protection unit 30 and a protective cover 40 to enable direct lightning protection in the shackle 10 portion.

The auxiliary lightning protection unit 30 is in the form of a normal lightning rod and is installed using an adapter fixing rod 12. For example, it includes a nut part 31 at the bottom and is connected to the adapter fixing rod (31) through the nut part 31. 12) is screwed into place. Of course, the auxiliary lightning protection unit 30 is not limited to the screw type and can be installed in various ways, such as the screw type.

The auxiliary lightning protection unit 30 includes an auxiliary ground wire 32, and the auxiliary ground wire 32 is connected to the ground wire 6 and is grounded through the ground wire 6.

In addition, the auxiliary ground wire 32 is not limited to being connected to the ground wire 6 exposed to the outside of the electric pole 2, but may be connected to a ground wire embedded in the electric pole 6, and in this case, the auxiliary ground wire 32 is not limited to being connected to the ground wire 6 exposed to the outside of the electric pole 2. (32) can be wired into Jeonju (2) after passing through Gyeongwangeum (3). In addition, it is possible to construct a ground wire separately from the auxiliary ground wire 32 and connect it to the ground wire embedded in the electric pole (2).

In addition, it is possible to separately configure the ground wire of the auxiliary lightning protection unit 30 while replacing the auxiliary ground wire 32 with an insulated connection wire, and the connection wire functions to support the ground wire 6 so as not to shake.

The auxiliary lightning protection unit 30 is installed and used as needed.

The protective cover 40 is installed next to the auxiliary lightning arrester 30 and surrounds the circumference of the auxiliary lightning arrester 30 to protect the auxiliary lightning arrester 30 from external collisions and is made of an insulating material to protect the auxiliary lightning arrester 30. ) eliminates the lightning protection function.

The protective cover 40 has a groove in which a portion of the peripheral portion is open for inserting the auxiliary lightning protection unit 30 therein, and has a flat upper surface.

The protective cover 40 is installed in a floating state on top of the gyeongwangeum (3) through a post 41 fixed to the gyeongwangeum (3).

There are two ways for the protective cover 40 to protect the auxiliary lightning arrester 30. A rail 3-3 is formed on the upper surface of the light fixture 3 and the post 41 of the protective cover 40 is used. ) is installed on the rail (3-3) and moves along the rail (3-3). The shackle (10) moves while the post (41) is fixed or moved, and the auxiliary lightning arrester (30) is provided with a protective cover ( 40) is possible.

The post 41 has a bottom plate at the bottom, and bolt-type fasteners are installed on the bottom plate to maintain the fixed state on the gyeongwangeum (3) or rail (3-3).

The rail 3-3 can have various shapes, such as a chin shape surrounding both circumferences of the bottom plate formed at the bottom of the post 41, a long hole shape, etc.

The distribution line insulator (4) and shackle (10) are placed at the end of the light rail (3), and a situation may occur where the shackle (10) moves due to a change in the wiring environment of the distribution line (1). In this case, the shackle (10) may move. The shackle (10) may be configured to move so that the movement of (10) does not affect the adapter (20).

For example, as shown in FIG. 4, the auxiliary ground wire 32 is connected on both sides in the longitudinal direction to the first and second sockets 33 and 34 formed on the ground wire 6 and the auxiliary lightning protection unit 30, respectively.

The first and second sockets 33 and 34 have a connection part connected to the ground wire 6 and the auxiliary ground wire 32 formed inside, an insulating part formed outside the connection part, and both sides of the auxiliary ground wire 32 in the longitudinal direction are formed as above. They are inserted so that they are separated from each other at the connection part.

As shown in Figure 5, the shackle connection portion 22 of the adapter 20 is connected to the first connection portion 22-1 connected to the adapter body 21 and the adapter fixing rod 12, while the first connection portion 22- It includes a second connection part (22-2) connected to 1) so that the length is adjustable, and the first connection part (22-1) has a circular hole, while the second connection part (22-2) includes a long hole. A sliding pin (22-3) is coupled to the hole and the long hole, and through this configuration, the first and second connection parts (22-1, 22-2) have a structure in which the length can be adjusted and moved.

Therefore, when the shackle 10 moves away from the adapter 20, the second connection part 22-2 moves away from the first connection part 22-1, and at this time, the auxiliary ground wire 32 ) has no tensile force and cannot expand or contract, so both sides in the longitudinal direction fall out of the first and second sockets 33 and 34, and eventually the auxiliary lightning arrester 30 is disconnected from the ground wire 6.

The bottom of the connection portion of the first and second sockets 33 and 34 is formed to be inclined downward from the inside toward the inlet so that the auxiliary ground wire 32 can be easily removed from the first and second sockets 33 and 34. In addition, the auxiliary ground wire ( 32) may be connected to an inflexible support and be configured to fall out of the first and second sockets 33 and 34 without bending.

At this time, the auxiliary lightning arrester 30 moves and is inserted into the inside of the protective cover 40, and thus the auxiliary lightning arrester 30 is protected from lightning.

At this time, a support bar 35 may be included to prevent the central portion of the auxiliary ground wire 32 from sagging downward and both sides from being pulled out of the first and second sockets 33 and 34 under normal circumstances.

The support 35 can be erected on one or more sides of the first and second connection parts 22-1 and 22-2, and is not limited to that shown in the drawings.
