Abstract

The utility model relates to the electric power industry, in particular, to devices for protecting the support and tension strings of insulators of overhead power transmission lines of 6-1150 kV voltage from the waste products of birds and birds from the negative effects of the overhead power transmission line itself. The device is installed on the traverse 1 of the overhead line in close proximity to the garlands 2 or a group of devices along the significant length of the traverse 1. It is an anti-bite element 3, that is, an element that does not allow birds to land and build nests on it. The anti-bite element 3 is made of an insulating material, for example, of one part or composite, and is made in the form of a conical or pyramidal shell or in the form of a truncated at least one plane of the conical or pyramidal shell. There is also an option for manufacturing the anti-crib element 3 in the form of a full-volume structure. The anti-bite element 3 is attached to the traverse 1 or some other structure of the overhead line for a similar purpose by means of the mounting unit 4, which is a separate unit from the anti-bite element 3 or structurally combined with the anti-bite element 3. The device is a simple, efficient and reliable universal device, since almost completely eliminates damage to lines with insulating pendants on the support and pin insulators due to the landing and nesting of birds on them and at the same time protecting to infect the birds themselves from electric shock. 2 s.p. f-ly; 1 ill.

Description

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

Known bird protection device for the end supports of power lines with pin insulators, containing a glass-shaped hood made of electrical insulating 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, also the device is equipped with fastening means for wires in the form of clamps or bandages for fixing the placement of wires inside the corrugated channels, characterized in that the length of the corrugated cable the bulk with 15-20 corrugations is 50-70 cm with an angle at the apex (depression) 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 an overhead power line if birds sit (nest) on the traverse of the line in close proximity to garlands, which is essential limits the functionality of the widespread use of this well-known technical solution.

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 a 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 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 protects birds when they land on the cross-arms of line supports.

The applicant set himself the practical task of creating an effective device simple in design and affordable to protect the garland of insulators of overhead power lines 6-1150 kV and birds from the negative effects of the overhead power line itself. This positive technical result was achieved due to the combination of essential structural features of the claimed device for protecting garlands of 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: “Protection device garlands of insulators of overhead power transmission lines of 6-1150 kV from the waste products of birds and birds from the negative effects of the air A power transmission line installed on a traverse or other similar overhead line structures in close proximity to garlands or a group of devices along a considerable length of the traverse is at least one anti-bite element made in the form of a pyramidal shell, with each said anti-bite the element is attached to the traverse or other similar structures of the overhead line by means of a fastening unit structurally integrated with the anti-slip element. ”

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a general view of a device for protecting garlands of overhead line insulators

power transmission of 6-1150 kV from the waste products of birds and birds from the negative effects of the overhead power line itself, made in accordance with this utility model.

The inventive device for protecting garlands of 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 is installed on the crosshead 1 of the overhead line in close proximity to the garlands 2 or a group of devices along a significant length of the crosshead 1. It represents antiprison element 3, that is, an element that does not allow birds to land and build nests on it. The anti-bite element 3 is made of an insulating material compound and is made in the form of a pyramidal shell. The anti-bite element 3 is attached to the traverse 1 or some other structures of the overhead line of a similar purpose by means of the mounting unit 4, structurally combined with the anti-bite element 3.

The utility model works as follows.

The device is mounted by means of a mounting unit 4 on the crosshead 1 of the overhead power line in close proximity to the garlands of insulators 2, if it is required to be protected from landing on it in an area where mostly small birds live, or it is attached by a group of devices along a significant length of the crosshead 1 of the overhead line power transmission, when it is required to prevent the landing and nesting of large birds (cranes, storks, etc.) living in the area of passage of the line in order to protect them from death and from short circuits and unintentional line outages. The smooth surfaces of the pyramidal shell of the anti-priest element 3 do not allow birds, both small and large, to fix on it and build their nests.

The inventive device for the protection of garlands of insulators overhead lines

6-1150 kV power transmission from the waste products of birds and birds from the negative effects of the overhead power line itself is a fairly simple, efficient and reliable universal device, since it almost completely eliminates damage to lines with insulating pendants 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.
