Description

[0001] Fixing equipment of aerial power distribution line [0002]

The present invention relates to a machining and distribution line fixing mechanism having a lightning arrester function, and more specifically, to prevent a bird from nesting around a beam of a telephone pole to solve a problem such as a short circuit accident, And more particularly, to a machining and distribution line fixing mechanism having a lightning protection function capable of preventing a danger such as an accident, preventing the machining distribution line from being stably supported and firmly fixed, and also preventing unauthorized removal.

Generally, power generated by a power plant is transmitted to each substation with high-voltage power through a power transmission line such as a power transmission tower. Substations are then subjected to various stages of transforming process and used by cables And the distribution process that will be supplied to each region.

At this time, the electric power supply to the public is supplied through the electric pole installed at regular intervals, and the connection at each electric pole is connected by using the jumper wire.

In other words, a distribution cable to be connected to a telephone pole is connected to both sides of the wire installed on both sides of the upper part of the main pole through an insulator, and a jumper wire is connected between the insulators. So that it can be supported.

Such a conventional technique is the registered patent No. 10-0989444.

In the conventional technology as described above, since the fixing wire is used to fix the power distribution line on the upper portion of the insulator, the operation is cumbersome and takes a long time, and the fixed portion is naturally released after a certain period of time There was a problem that it was not possible to secure a certain fixation. In particular, when the birds made the nest using the branches in the vicinity of the Jeonju, there was a problem that the branches often caused accidents such as electrical shorts.

In addition, since the insulator is exposed to the outside, there is a serious problem that leads to an electric shock accident when the operator inadvertently touches it, and is easily exposed to the risk of lightning, which is of course very vulnerable.

The use state and operation of the present invention having the above-described configuration will now be described.

Figs. 7A to 7E are views for explaining the operation of the processing distribution line fixing mechanism having the lightning protection function according to the present invention.

2, FIG. 4 and FIG. 7A, first, a nut (see FIG. 2) is fastened to the connecting bolt 13 in a state where the connecting bolt 13 of the insulator 10 is fitted into the full- So that the insulator (10) is fixed to the precious metal (S).

4, the gripper 20 is then placed on the pressurizing mouth accommodating portion 11a, and then the elevating rod 21 is inserted into the elevating rod receiving portion 11c, 12a can be pulled inward through the lower end of the lifting rod 21 and when the projection 12a of the release preventing rod 12 is pulled inward of the lifting rod 21, So that the projections 12a of the release preventing rods 12 are arranged on the latching protrusions 21a of the raising and lowering rods 21.

At this time, the stopper 30 is held without being removed from the insulator 10 so that the gripper 20 is supported by the air inside the elevating rod 11c.

7B and 7C, when the engagement of the insulator 10 and the gripper 20 is completed, the processing power distribution line L is drawn into the gap between the pushing openings 23 of the gripper 20, When the stopper 30 is then removed from the insulator 10, the elevating rod 21 of the gripper 20 is lowered by the own weight of the machining distribution line L and is naturally drawn inward into the elevating rod 11c, The pressure applying member 23 is also naturally drawn into the pressure receiving member 11a.

At this time, the O-ring 22 seals the inner circumferential surface of the ascending / descending wall portion 11c and the ascending / descending bar 21 in an airtight manner in the process of pulling the ascending / descending bar 21 to the inside of the ascending / The inside air of the usable portion 11c is discharged to the outside through the air line 11d.

Further, the pushing-out port 23 is switched to a state in which the pushing-in port 23 is pulled into the inside of the pushing-pin receiving portion 11a, and the pushing-out port 23 is strongly pressed and fixed do.

When the fixing of the machining distribution line L is completed as described above, the stopper 30 is fitted into the air line 11d as shown in Fig. 7D.

7D, when a force is applied to the lightning protection lid 40 in a downward direction in a state where the lightning protection lid 40 is disposed on the upper portion of the insulator 10, the pressure distribution line The machining distribution line L is steadily guided and moved toward the wire seating section 43. The machining distribution line L is then moved to the wire seating section 43 And the installation is completed while the circumference is inserted in a close contact state.

On the other hand, if a strong wind such as a typhoon acts on the processing power distribution line L, the processing power distribution line L may be swung by this, and lifting may occur at a portion where the processing power distribution line L is fixed.

7E, even if the gripper 20 fixing the machining distribution line L is subjected to the upward force F by the machining power distribution line L, the negative pressure F And the magnetic force between the permanent magnet 14 and the magnetic body 21c can be suppressed as much as possible due to the magnetic force between the permanent magnets 14 and the magnetic bodies 21c. Therefore, the problem that the fixed state of the machining distribution line L is released can be fundamentally eliminated There is an advantage.

In addition, the present invention has an advantage that the problem of nesting algae around the wax S as the sunlight reflected by the reflection plate 54 of the erection mechanism 50 interferes with the view of the algae.
