Description

The utility model relates to the field of electric power industry, in particular, to devices for protection against the vital activity of birds during their landing and nesting on garlands of insulators of overhead power lines, for example, with a voltage of 6-35 kV.

A bird protection device for end supports of power lines with pin insulators is known, comprising a glass-shaped hood made of electrical insulation material with a vertical plate and corrugated channels of the ∩-shaped section with open lower edges of the channels and the hood and a common cavity made at the same time as the hood, and the device is also equipped with fastening means for wires in the form of clamps or bandages to fix the placement of wires inside the corrugated channels, the length of the corrugated channels from 15-20 corrugations frame is 50-70 cm with an angle at the top (bottom) of the corrugation 80-100 °. [one].

This device is intended solely to protect birds during their landing or nesting on the elements of the end supports of overhead power lines with pin insulators, which significantly reduces its functionality for using other design options on the lines.

It is also known 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 [2].

This well-known technical solution, as shown by the practice of its application, does not provide 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.

The applicant set a specific goal - to develop a device for the protection of overhead power lines with a voltage of 6-35 kV from the vital activity of birds, which almost completely eliminates damage to lines due to landing and nesting on them (pollution and overlapping insulation, disconnecting lines, etc.) , and at the same time protect the birds themselves from electric shock. This positive technical result was achieved due to the combination of essential design features of the claimed device for protecting overhead power lines with a voltage of 6-35 kV from bird vital activity, given in the following utility model formula: "device for protecting overhead power lines with a voltage of 6-35 kV from bird vital activity, providing protection of pin and support linear insulators and adjacent sections of the line wire, as well as preventing electric shock to birds, containing at least two protective casing of insulating material, made with straight or corrugated sections of the cross section of an arched view; the end part of at least one of the housings is made in the form of a glass, which allows to cover the insulator, and the end part of at least the second of the housings is made in the form of a L-shaped segment, said end parts of each of the housings are connected to each other by means of a device made in the form of a composite sliding latch inserted into the axial hole between them and allowing the casings to move relative to their axis at an angle from 0 ° to 60 °, and in the second end parts of the casings there are slots for water line; the number of straight or corrugated sections of the arched cross-section is selected in the range from 1 to 45 ".

The essence of the utility model is illustrated by drawings, where in FIG. 1 is a general view of a device for protecting overhead power lines with a voltage of 6-35 kV from the vital activity of birds, made according to a utility model, a top view of the device; in FIG. 2 is the same as in FIG. 1, bottom view of the device.

The inventive device for the protection of overhead power lines 6-35 kV from the vital activity of birds provides protection of the pin and support line insulators and adjacent sections of the wire of the overhead power line and prevents electric shock to the birds. It consists, for example, of two protective casings 1 and 2, made of insulating material and having straight or corrugated sections 3 of the cross section of an arched shape. The end part of the casing 1 is made in the form of a cup 4, which allows to completely cover the insulator (not shown), and the end part of the second casing 2 is made in the form of an L-shaped segment 5. The end parts 4, 5 of each of the casing 1, 2 are connected to each other by devices, made in the form of a sliding latch 6, which is inserted into the axial hole 7 between the casings 1, 2 and allowing them to move relative to their vertical axis 8 at an angle in the range from 0 ° to 60 °. In the second end parts 9 of the housings 1, 2, slots 10 are provided for a power line wire (not shown).

The number of straight or corrugated sections 3 of the cross section of the arched view is selected in the range from 1 to 45.

The utility model works as follows.

The proposed device can be mounted on both pin and support linear insulators, while protecting both them and adjacent sections of the wire overhead power lines. The cup 4 of the end part of the casing 1 completely closes the insulator body, while the segment 5 of the end part of the casing 2 is connected to the cup 4 of the end part of the casing 1, for which a sliding latch 6 is inserted into the axial hole 7 between the casing 1, 2, the components of which are bursting, fixing the required angle of rotation of the casings 1, 2 relative to each other for a particular embodiment of the insulating suspension and the line. Due to the slots 10, sections of the wire of the overhead power line adjacent to the insulator are also protected.

The inventive device for the protection of overhead power lines with a voltage of 6-35 kV from the vital activity of birds is a fairly simple, effective and reliable universal device, since it almost completely eliminates damage to lines with insulating suspensions on support and pin insulators due to landing and nesting on them (pollution and overlapping insulation, disconnecting lines, etc.) and at the same time protect the birds themselves from electric shock. MZVA LLC has launched mass production of such devices and their delivery to electric power facilities.
