Description

Apparatus for preventing stoppage current at electric pole}

The present invention relates to a device for preventing electrical conduction of a high-voltage cable, which can prevent short circuits and blackouts caused by bird droppings. More specifically, the main body installed near the upper transmission tower of the insulator that binds the wires does not flow electricity. The upper cover and the lower cover is formed of a non-conductor, the fastening hole is formed on both sides of the edge and the inner central portion has an arc-shaped curved portion, and the curved portion of the upper cover and the lower cover to increase the tightening force between the insulator and the cover. Packing to be fitted in, and the upper cover and the lower cover is overlapped and formed by a fastener through the fastening hole formed in the space formed in the center of the cover, and then prevent electric conduction of the high-voltage cable fixed to the mandrel that is integrally assembled with the insulator Relates to a device.

Generally, the metal material around the high voltage wire where the insulator is fixed and the bolt, which is a fixed part, will be nested by a bird biting branches, leaves, rice straws, wires, or electrical conductors. Since the occurrence of electric leakage or power failure due to electrocution or spark or short circuit of birds occurs frequently, there is a problem that a bird nest should be removed with a lot of manpower and expense.

In addition, KEPCO has been dismantling the bird nest installed on top of the telephone pole by applying considerable manpower and cost, and due to the nature of the bird, it is not a few days after being demolished, and the nest is not placed again, so it does not show a great effect.

Therefore, various devices have been developed and used to prevent the power failure caused by birds.

On the other hand, since the algae excretion contains potassium, which is an alkali metal, as a conductive material, the algae excretion causes flashover to both ends of the azaleas when there is agriculture, light mist, and dewy moisture while the algae excretion is fixed on the insulator surface. There is this.

That is, there is a disadvantage in that both ends of the child-studs flashes by being energized with insulated droppings by agricultural drizzle.

The technical problem to be solved by the present invention for solving the above problems is, by forming a suspension cover on the upper side of the insulator formed in the transmission tower to protect the insulator from bird droppings while preventing the ground fault electric conduction of the high-voltage cable It is for providing a prevention device.

As a means for achieving the above-described technical problem, the main body is installed in the vicinity of the upper transmission tower of the insulator that binds the electric wire is composed of non-conducting non-conductor, fastening holes are formed on both sides of the edge and arc-shaped curved portion in the inner central portion The upper cover and the lower cover, and the packing to be fitted to the bent portion of the upper cover and the lower cover to increase the tightening force between the insulator and the cover, and overlaps the upper cover and the lower cover to the fastener through the fastening hole By fastening is characterized in that the space formed in the center of the cover is formed.

According to the present invention, since bird droppings can be prevented from adhering to the surface of the insulator, it is possible to prevent failure due to the occurrence of flashover at both ends of the insulator.

In addition, the suspension insulator pollution prevention device of the present invention has the effect of being easy to install and dismantle while not falling off in rain or vibration.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part includes a certain component, this means that it may further include other components rather than controlling other components unless otherwise stated.

First, the present invention is to form a lower cover 13 in close contact with the upper cover 12, respectively, as shown in Figures 1 and 3, the central portion of the upper cover 12 and the lower cover 13 of the arc-shaped The upper curved portion 14 and the lower curved portion 15 are respectively formed.

The packing 20 and 21 are inserted into and fixed to the upper curved portion 14 and the lower curved portion 15 to increase the tightening force between the upper cover 12 and the lower cover 12.

In this case, the upper curved portion 14 and the lower curved portion 15 are integrally fitted and fixed to the fixing grooves 22 and 23 formed outside the packings 20 and 21.

Here, the rotational bumps 16 and 17 are formed at the center of the upper curved portion 14 and the lower curved portion 15, and the rotational bumps 16 and 17 are packed 20 and 21 as shown in FIG. 5. It is inserted into and fixed to the recessed part 24 formed inside.

Here, grooves 25 and 26 are formed inside the packings 20 and 21 so that the tightening force is increased when the main body 40 is fastened to the core rod 11 of the insulator 10.

That is, as shown in FIG. 5, the grooves 25 and 26 are formed into spaces, and thus, the grooves 25 and 26 may be expanded and contracted by the core rods 11 to be inserted into the packings 20 and 21. Configuration.

On the other hand, the upper cover 12 and the lower cover 13 is fixed in such a way that a part overlaps, at this time to match the fastening holes 30, 31, 32, 33, then separate fastening bolts 34 Through and then assembled and fixed with the nut 35.

Here, the upper cover 12 and the lower cover 13 is preferably made of a material of non-conducting electricity does not flow, and the packing 20 is fitted to the arc-shaped curved portions 14, 15 formed in the center It is natural that the 21 is also formed of a rubber material.

And, the overall shape of the upper cover 12 and the lower cover 13, as shown in Figure 2 (a) (b) can be formed different, which can be used to change depending on the single and double suspension insulator used have.

Therefore, the core rod 11 is inserted into a plurality of insulators 10 stacked as shown in FIG. 4, and then the main body 40 including the upper cover 12 and the lower cover 13 is inserted above the core rod 11. do.

At this time. The core rod 11 is inserted into the space portion 41 formed in the center of the main body 40 formed of the upper cover 12 and the lower cover 13, and then the main body 40 and the other by the separate locking member 42. The insulator 10 can be firmly supported.

On the other hand, the main body 40 for protecting the insulator 10 fixed to the mandrel 11 is configured by differently configuring the size of the upper cover 12 and the lower cover 13 as shown in (a) (b) of FIG. The protection area can be expanded.

Since the main body 40 assembled as described above covers the upper side of the insulator 10 formed in the transmission tower as a whole, it is possible to prevent the droppings of birds from directly falling on the insulator 10 surface.

As a result, according to the present invention, because bird droppings can be prevented from sticking to the surface of the insulator, it is possible to prevent failure due to the occurrence of flashover at both ends of the insulator.

In addition, the suspension insulator pollution prevention device of the present invention has the effect of being easy to install and dismantle while not falling off in rain or vibration.

It will be understood by those of ordinary skill in the art that the foregoing description of the present invention has been presented for purposes of illustration and that those skilled in the art will readily understand that various changes in form and details may be made without departing from the spirit and scope of the present invention. will be.

It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined form.
