Description

Overhead distribution line fixing mechanism with collision prevention function between wires

The present invention relates to an overhead distribution line fixing mechanism having a collision prevention function between wires.

In general, the connection point of the power line on the high-voltage or extra-high voltage (23 kV) overhead distribution line is composed of an insulated wire, a human clamp, a human clamp cover and an insulator, and is connected to a support (electric pole).

The human clamp cover connecting the insulator and the electric wire is covered with the human clamp cover, so the charging part of the connection point can be insulated and used.

This case can be done under the premise that there is no artificial approach such as live wire work.

Therefore, when working with a live wire, an insulating cover for a live wire operation with sufficient insulation properties and mechanically excellent strength for safety is essential because the worker or equipment for work is frequently accessed.

As a prior art related to such an insulation cover, there is Republic of Korea Patent Registration No. 10-2091609 (extensible wire cover for live wire work of overhead distribution lines), which allows length adjustment according to the work range during live wire work of overhead distribution lines. A technology that can safely perform live wire work in a state in which the entire range is covered is disclosed.

However, in the prior art, when an external force is applied to an overhead distribution line, the overhead distribution line moves horizontally and collides with a neighboring overhead distribution line, thereby causing damage and electric short circuit.

Subsequently, the wire fixing unit 200 is composed of an insulator cover 210 and a cover fixture 220 .

The insulator cover 210 is a synthetic resin material of an insulating material. In this embodiment, the insulator cover 210 is detachably coupled to the line post insulator 100 and wraps the overhead distribution line L installed on the upper surface of the line post insulator 100 so as not to be exposed. It plays a role of stably fixing and suppressing the transverse movement caused by external force. The insulator cover 210 includes a cover body 211 , a wire stopper 212 , a seat accommodating part 213 , a wire accommodating part 214 , a fixture accommodating part 215 and a coupling rod 216 .

As the insulator cover 210 is installed on the insulator body 110 through the cover fixture 220 as a medium, it is possible to fundamentally solve the problem of the insulator cover 210 being separated from the insulator body 110 without permission. .

The collision prevention unit 300 is composed of a branch sleeve 310, a branch line fixing ring 320, and a housing 330, and in this embodiment, branching from the overhead distribution line (L) can be performed while adjacent processing It serves to prevent collision with the distribution line (L).

The branch sleeve 310 is a member made of a conductive material consisting of a clamping part 311, a branch line seating part 312, and a fixing pin 313. In this embodiment, it is attached to the outer peripheral surface of the overhead distribution line (L). It serves to electrically interconnect the overhead distribution line (L) and the branch line (L'). Here, the clamping part 311 is firmly fixed to the outer circumferential surface of the overhead power distribution line (L) while being tightened by the pressing force of the tool in a state where it is attached to the outer circumferential surface of the overhead power distribution line (L). A branch line seating part 312 having a concave recessed shape like the cross-section of a pulley is integrally formed on the intermediate outer peripheral surface of the clamping part 311, and the branch line L' is wound around the branch line seating part 312. is accepted as

On the other hand, when the branch line L' is wound around the branch line seating part 312 and fixed, the branch line L' slips along the inner surface of the branch line seating part 312, and when this process is repeated, the clamping part 311 ) has a problem in that it rotates around the outer peripheral surface of the overhead distribution line (L).

Accordingly, in this embodiment, the conical fixing pin 313 is integrally formed on the inner peripheral surface of the clamping part 311 and the inner surface of the branch line seating part 312 . Here, the fixing pin 313 formed on the inner circumferential surface of the clamping part 311 digs into the overhead distribution line L when the clamping portion 311 is pressed to form an integrated structure with the overhead distribution line L, and the branch line seating portion ( In the fixing pin 313 formed on the 312 , the fixing pin 313 digs into the inside of the branch line L' by its own weight while the branch line L' is accommodated to form an integrated structure. Accordingly, it is possible to firmly fix the overhead distribution line (L) and the branch line (L') to the branch sleeve 310 via the fixing pin 313 .

The branch line fixing ring 320, as shown in Fig. 4b, is inserted into the overlapping branch line (L') in an annular shape and serves to press and fix the overlapped portion.

The housing 330 is a member of an insulating material composed of the first and second bodies 331A and 331B, the sleeve receiving part 332, the branch line fitting part 333, the support 334 and the arc plate 335. In the case of an example, the branch sleeve 310 is wrapped so as not to be exposed to the outside, and serves to prevent a collision between the adjacent overhead distribution lines (L) when the overhead distribution line (L) is transversely moved by an external force.

The first and second bodies 331A and 331B form a 'T' shape as a whole, are divided and are coupled to each other. These first and second bodies (331A, 331B) can be forcibly opened or closed since only the both sides and the lower end are incised. In addition, the sleeve receiving portion 332 is formed in the front and rear directions inside the first and second bodies 331A and 331B, and the branch line fitting portion 333 is integrally formed in the vertical direction. Here, the branch sleeve 310 is removably accommodated in the sleeve accommodating part 332 , and the branch line L' fitted to the sleeve accommodating part 332 is removably accommodated in the branch line fitting part 333 .

On the other hand, the support 334 extending in the transverse direction is integrally formed on the outer peripheral surface of the first and second bodies 331A and 331B, and an arc plate 335 is installed at the end of the support 334 . Here, the arc plate 335 is disposed to be spaced apart via the support 334 and serves to prevent the overhead distribution lines L transverse by an external force from colliding with each other. As can be seen here, the first and second bodies 331A and 331B, the support 334, and the arc plate 335 are made of synthetic resin material having a certain strength in that it must be able to block the force of the transverse overhead distribution line (L). it is preferable

5A and 5B are diagrams for explaining the state of use of the wire fixing unit in the overhead distribution wire fixing mechanism having a collision prevention function between wires according to the present invention, which will be described with reference to the following.

2, the coupling bolt 120 constituting the line post insulator 100 is inserted through the bolt insertion hole 2a of the arm iron 2 installed on the electric pole 1, and then the coupling bolt 120 ) and fasten the nut to fix the line post insulator 100 to the arm iron (2).

In the installed state as described above, as shown in Fig. 5a, the overhead distribution line (L) is placed on the wire receiving hole 130 of the line post insulator 100, and then the overhead distribution line (L) is connected to the line post using a binder. It is fixed to the insulator (100).

When the overhead distribution wire (L) is fixed to the line post insulator 100 as described above, the insulator cover 210 constituting the wire fixing unit 200 is coupled to the line post insulator 100, and this will be described in more detail. If you do:

First, when the coupling rod 216 constituting the insulator cover 210 is inserted in line with the coupling hole 111 of the insulator body 110, the wire seat 130 and the overhead distribution line (L) during the insertion process. is accommodated while being naturally inserted into the wire receiving portion 214 of the seat hole receiving portion 213 and the wire stopper 212 .

Referring to FIG. 5B , when the installation of the insulator cover 210 is completed as described above, the insulator cover 210 is firmly fixed to the insulator body 110 using the cover fixture 220 , and this Specifically, it is as follows.

First, when the cover fixture 220 is strongly pressed from top to bottom in a state where the insulator cover 210 is disposed between the coupling parts 223 constituting the cover fixture 220, the vertical part 222 is forcibly opened. It is fitted to the cover body 211 while falling, and in this process, the horizontal part 221 is drawn into the fixture accommodating part 215 and is abutted, and the coupling part 223 is coupled to the convex part of the insulator body 110 .

By this interaction, the insulator cover 210 is firmly fixed to the line post insulator 100 , thereby minimizing the unauthorized separation of the insulator cover 210 from the line post insulator 100 .

In addition, as the overhead distribution line (L) is accommodated inside the seating hole receiving portion 213 and the wire receiving portion 214, even if an external force acts on the overhead distribution line (L), the insulator cover 210 is the overhead distribution line (L) Since part of the traverse is fixed, the degree of transverse movement can be greatly reduced, and accordingly, collisions between adjacent overhead distribution lines (L) can be suppressed as much as possible.

6A to 6C are views for explaining the state of use of the collision prevention unit in the overhead distribution line fixing mechanism having a collision prevention function between wires according to the present invention, which will be described with reference to the following.

First, the branch sleeve 310 is inserted into the outer circumferential surface of the overhead distribution line L, and then the clamping parts 311 provided at both ends of the branch sleeve 310 are pressed using a tool, respectively.

As described above, the clamping part 311 is fixed to the overhead distribution line (L) while being pressed and closed. Accordingly, the overhead distribution line L and the clamping part 311 are more firmly fixed.

When the branch sleeve 310 is mounted on the overhead distribution line L as described above, the branch line L' is wound around the branch sleeve 310 and fixed, which will be described in more detail as follows.

First, in a state in which the branch line L' is wound around the branch line seating portion 312 of the branch sleeve 310, the wound end portion is pressed using the branch wire fixing ring 320 to fix it so as not to be loosened.

At this time, the branch line L' is strongly adhered to the inner surface of the branch line seating part 312 by its own weight. Accordingly, the branch sleeve 310 and the branch line L' form an integrated structure.

When the branch line L' is connected to the branch sleeve 310 as described above, the branching operation is completed when the branch sleeve 310 and the branch line L' are wrapped using the housing 330.

On the other hand, when the branching operation is completed as described above, when the overhead distribution line (L) moves transversely by external force, there is a high risk of colliding with the neighboring overhead distribution line (L). As the support 334 and the arc plate 335 of the 300 block, it is possible to minimize the collision between the overhead distribution lines (L).

Although the present invention has been described in detail only with respect to the specific embodiments described, it is natural for those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention, and it is natural that such variations and modifications belong to the appended claims.
