Description

The utility model relates to the field of electric power industry, in particular, to devices for protecting overhead transmission lines of 6 ÷ 1150 kV from the waste products of birds and birds from the negative effects of the overhead transmission line itself.

A device for protecting birds from electric shock on an overhead power line, containing at least two cupped elements designed for installation on a pin insulator, and casing channels designed for installation on wires of power lines [1].

This well-known technical solution, as shown by the practice of its application, does not allow complete protection of birds from electric shock, since it contains sections of the insulating suspension that are accessible for birds to touch, for example, in insulating suspensions using linear support insulators, as well as this device does not protect birds when they land on the cross-arms of the line supports.

The closest technical solution in relation to the proposed one is a device for protecting insulators of overhead power lines with a voltage of 6 ÷ 1150 kV from the waste products of birds and birds from the negative effects of the overhead power line itself, containing at least one antipruritic element and a mounting unit, each antipruritic the element is made in the form of a flat or spatial part made of a dielectric material or of an electrically conductive material with a dielectric coating of its surface or with a dielectric coating in separate places of its surface and equipped with rods with an end shape that excludes the possibility of injury to the bird if accidentally touched or attempted to land, while the number of anti-interference elements is selected from 1 to 200, the number of rods from 2 to 300 [2] .

Nevertheless, this well-known technical solution cannot be considered universal enough, due to its limited functionality, which does not allow to provide effective protection for all sections of overhead power lines where birds can land, in particular on overhead power lines with pin and support linear insulators.

The applicant set himself a specific goal, namely, to create an effective device simple in design and affordable to protect the insulators of overhead power lines 6 ÷ 1150 kV and birds from the negative effects of the overhead power line with a constructive anti-spill element that more fully meets stringent requirements ornithologists, as well as allowing you to reliably close possible places of landing and nesting birds, in particular, at the pin and support linear insulators. This positive technical result was achieved due to the combination of essential structural features of the claimed device for protecting insulators of overhead power lines 6 ÷ 1150 kV from the waste products of birds and birds from the negative effects of the overhead power line itself, given in the following utility model formula: “device for protecting insulators 6 ÷ 1150 kV overhead power transmission lines from the waste products of birds and birds from the negative effects of the air itself a power line containing at least one anti-bite element and a mount, each anti-bite element is made in the form of a flat or spatial part made of a dielectric material or of an electrically conductive material with a dielectric coating of its entire surface or with a dielectric coating in separate places of its surface and equipped with rods with an end shape that excludes the possibility of injury to the bird in case of accidental contact or attempted landing, while the number of elements are selected from 1 to 200, the number of rods from 2 to 300; it is located away from the insulators, the height of the entire device, measured from the attachment point to the upper edge vertically corresponds to the ratio (0.2 ... 1.4) N, where N is the height from the crosshead to the top of the pin or support linear insulator, and the distance l from antiprison elements to the insulating body of the insulator is greater than or equal to 10 mm. ”

The essence of the utility model is illustrated by drawings, where in FIG. 1 is a perspective view of a device for protecting insulators of overhead power lines of 6 ÷ 1150 kV voltage from the waste products of birds and birds from the negative effects of the overhead power line itself, made in accordance with the present invention.

The inventive device for the protection of overhead power lines 6 ÷ 1150 kV from the waste products of birds and birds from the negative effects of the overhead power line itself consists of an anti-splicing element 1 and a mounting unit 2. Anti-splicing element (there may be several, for example, from 1 to 200 pieces) fixed on linear insulators (support or pin) 3, is made in the form of a spatial part 1 made of a dielectric material or of an electrically conductive material with a dielectric coating throughout rhnosti or dielectric coating in places of its surface. This design of the anti-priest element allows more fully and efficiently fulfill the rather stringent requirements of ornithologists presented to bird protection devices. On part 1 there are rods (from 2 to 300 pieces) 4, the end shape of which eliminates the possibility of injury to the bird in case of accidental contact or attempted landing. For this, the end shape of the rods 4 has special roundings 5 of a regular shape, for example, roundings 5 can be made in the form of a circle, ellipse, oval or cone, in the form of a semicircle. In cross section, the rods 4 are in the form of a circle, ellipse or polygon.

The height of the entire device, measured from the attachment point to the upper edge vertically, corresponds to the ratio (0.2 ... 1.4) N, where N is the height from the crosshead 6 to the top of the pin or reference linear insulator 3, and the distance l from the anti-slip elements to the insulating body of insulator 3 is chosen to be greater than or equal to 10 mm, which allows for reliable protection of birds and the overhead power line with linear (support or pin) insulators.

The proposed device allows you to effectively protect overhead power lines 6-1150 kV with linear (support or pin) insulators from the waste products of birds and birds from the negative effects of the overhead power line.
