Description

The invention relates to the field of electric power, in particular to devices for protecting birds from electric shock on overhead power lines with a voltage of 6-35 kV

A device for protecting birds from electric shock on an overhead power line, containing at least two cupped elements, designed to be installed on a pin insulator, and casing channels, designed to be installed on wires of power lines [2].

This well-known technical solution, as shown by the practice of its application, does not allow complete protection of birds from electric shock, since there remain sections of the insulating suspension that are accessible for birds to touch, for example, in insulating suspensions using linear support insulators, as well as does not protect birds when landing on traverse of line supports

-образного сечения с открытыми нижними кромками каналов и капота и общей полостью, также устройство снабжено средствами крепления на проводах в виде хомутов или бандажей для фиксации размещения проводов внутри гофрированных каналов, отличающееся тем, что длина гофрированных каналов с 15-20 гофрами составляет 50-70 см с углом на вершине (впадине) гофра 80-100° [1].A bird protection device for end supports of power lines with pin insulators is also known, comprising a glass-shaped hood made of electrical insulating material with a vertical plate and corrugated channels made integral with the hood

-shaped section with the lower edges of the channels and the hood open and a common cavity, the device is also equipped with fasteners on the wires in the form of clamps or bandages to fix the placement of wires inside the corrugated channels, characterized in that the length of the corrugated channels with 15-20 corrugations is 50-70 cm with an angle at the top (bottom) of the corrugation 80-100 ° [1].

This device is intended solely to protect birds during their landing or nesting on the end supports of overhead power lines with pin insulators and does not protect birds from the negative effects of overhead power lines if birds sit (nest) on the traverse of the line, which significantly limits the functionality of widespread use this famous technical solution.

The applicant set himself the task of developing an effective, simple in design and affordable technical solution, namely, a device for protecting birds from electric shock on overhead transmission lines of 6-35 kV, which occurs when a bird is on the beam, when it blocks with its body (for example, while feeding the chicks) a traverse element with some kind of phase wire line. This positive technical result was achieved due to the combination of essential structural features of the inventive device for protecting birds from electric shock on overhead power lines 6-35 kV, shown in the following claims: "device for protecting birds from electric shock on overhead power lines 6 -35 kV, which is a casing made of an insulating material or an electrical insulating casing, equipped with additional mounting brackets made of conductive material elements made of at least one part or composite and mounted on the grounded element of the traverse of the overhead line so that the body of the bird does not overlap between the grounded element of the traverse and at least one wire of the phase of the overhead line, the thickness of the insulating part of the casing is selected in the range from 0.2 to 15 mm, excluding its electrical breakdown; the casing is made of a cylindrical, pyramidal, ellipsoid or rectangular shape; the components of the casing are articulated to each other through a telescopic connection; rubber or plastic was chosen as the insulating material of the casing. ”

The invention is illustrated in FIG. 1, which shows in general terms a device for protecting birds from electric shock on overhead power lines of 6-35 kV, made in accordance with the present invention.

The inventive device for protecting birds from electric shock on overhead power lines 6-35 kV is a casing 1 made of an insulating material, while the insulating casing 1 can be equipped with additional fasteners made of a conductive material. It can be made of one part or composite, then its component parts are joined together, for example, according to the telescopic principle of connection. As the insulating material of the casing 1, rubber or plastic is selected. The casing 1 may be made of a cylindrical, pyramidal, ellipsoid, rectangular shape or some other geometric shape. The casing 1 is installed on the grounded element of the traverse 2 of the overhead line in such a way as to prevent the body of the bird from blocking between the grounded element of the traverse 2 and one of the wires 3, 4 (Fig. 1) of the phase of the overhead power line. The thickness of the insulating part of the casing 1 is selected in the range from 0.2 to 15 mm, which eliminates its electrical breakdown and at the same time does not interfere with the protection of birds from electric shock.

The invention works as follows.

The device (casing 2) is installed on a grounded crossarm 1 so as to close almost the entire space between, for example, support pin insulators 5, 6 and their attachment points 7, 8 of two phase wires 3, 4 of a multiphase overhead power transmission line (Fig. 1) . In this case, the bird’s body blocking (and, therefore, its death from electric shock) between the grounded elements of the crosshead 1 and any of the phase wires 3, 4 of the overhead power line is completely prevented, which is especially often the case during the feeding of chicks (since the bird at this time constantly spreads its wings).

The inventive device for protecting birds from electric shock on overhead power lines 6-35 kV, as shown by the practice of its application, simple in design, effective from the point of view of protecting birds from electric shock and reliable during long-term operation. MZVA LLC has launched mass production of such devices and their delivery to electric power facilities.
