SK502006A3 - Bird barrier for construction of high voltage transmission line - Google Patents

Abstract

The circular rim, which has the dielectric properties is attached to the insulator in a manner so that the wire which is under voltage is held approximately in the centre of the circular rim. The highest point of the circular rim bears a small plate with spikes preventing the birds from landing on what is in fact the highest point of the circular rim. The circular rim will also prevent the birds from getting into the dangerously close vicinity from the high voltage wire through stepping on the console supporting the insulators.

Preventing birds against the construction of high voltage overhead lines

Technical field

The invention relates to a mechanical barrier which is placed on the construction of high-voltage overhead lines and prevents the birds from contacting and falling on the non-insulated parts of the electrical poles, thus preventing the birds from killing by power jumps.

BACKGROUND OF THE INVENTION

Many patents disclose wiring and circuit diagrams to prevent birds from landing on high voltage poles. For example, these documents include solutions where the basis is an automatic sound signal that does not allow birds to land on the mast and scare it off. In practice, T-shaped devices have been tested, which have been mounted on the supporting brackets of high-voltage poles, and these should have prevented birds from landing at very dangerous poles. However, this protection of birds has not proved effective. The second solution tested in practice is the use of combs which are mounted on horizontal brackets of high voltage poles. However, this solution is also not very effective. The published Slovak patent application PP 810-96 describes a barrier to the construction of high-voltage power line carriers to prevent the killing of birds by a power jump and to prevent such transmission failures. This barrier is attached to the horizontal arms of the support point bracket between the conductors. The barrier is formed by a base with at least one triangle-shaped tooth. These triangles shall be attached to the structure of the line supports so as to completely fill the space between the two conductor insulators. Placing these barriers is time consuming and also costly, as a large number of triangular teeth are required.

SUMMARY OF THE INVENTION

The above-mentioned drawbacks are overcome by the solution according to the invention, which consists in attaching an approximately circular or circular hoop having dielectric properties around the vertical insulator with a high-voltage conductor. An approximately circular hoop can be understood to mean a hoop with an irregular circular shape, for example an elliptical shape. Said hoop is fastened to the bracket below the insulator by means of fastening means, for example a clamping sleeve wrapped on the bottom of the insulator. The ring hoop may be made of non-conducting homogeneous materials or a combination of non-conducting materials such as laminate composite, plastic, ceramic or a combination thereof. The ring hoop is fixed to the insulator so that the conductor through which the electricity flows is located approximately in the center of the hoop and the hoop is at least 250 mm or less from the conductor (center). The highest point of the hoop may be provided with a spike with or without spikes to prevent the bird from landing at this point. When two or more circular hoops having dielectric properties are placed on the horizontal mast of the mast, the hoops may be connected to their upper part by an auxiliary arm.

The hoop will also ensure that the birds do not come in dangerous proximity to the high-voltage conductor on the bracket on which the insulators are located, thus preventing the bird from being killed by a power jump.

DETAILED DESCRIPTION OF THE INVENTION

The object of the barrier is that a ring hoop 1 or an approximately ring hoop having dielectric properties is fastened around the vertical insulator 4 with the high-voltage conductor 5 on the mast bracket 6. The term approximately circular hoop can be understood to mean a hoop with an irregular circular shape, for example an elliptical shape. Said circular hoop 1 is fastened to the bracket 6 below or to the insulator 4 by fastening means 2, for example a clamping sleeve wrapped on the bottom of the insulator 4. The hoop I can be made of non-conductive homogeneous materials or a combination of non-conductive materials such as laminate, plastic, combinations thereof. The circular hoop 1 is fixed to the insulator 4 such that the conductor 5 through which the electric energy flows is located approximately in the center of the circular hoop 1 and the circular hoop 1 is at least 250 mm or less from the conductor 5 (center). The opposite outer side of the circular hoop 1 from the side with the fastening means 2 can be provided with a plate 3 with / without spikes 9, to prevent the bird from landing on this actually the highest point of the circular hoop 1. The ring hoop 1 also ensures that the birds do not come into dangerous proximity to the high-voltage conductor 5 on the bracket 6 on which the insulators 4 are located, thus avoiding a power jump and subsequent killing of the birds.

A further embodiment according to the preceding embodiment consists in that two or more circular hoops 1 or approximately circular hoops 1 having dielectric properties on the horizontal mast 7 of the mast, the upper part of the hoops 1 are connected by an auxiliary arm 8
