Description

The utility model relates to the electric power industry and can be used in devices to exclude the possibility of landing and nesting birds on the supports of overhead power lines.

A device is known for preventing birds from landing on a transmission line support (USSR author's certificate No. 953163, ЕНН 12/00, 08/28/1982), including repelling elements mounted on a support mounted on a support, a permanent magnet attached to the support and in contact with the support, one made of deterrent elements is made with a ring of non-magnetic material at the free end, while a layer of waterproof air-dried adhesive is applied to the surface of the magnet in contact with the support.

The disadvantage of the analogue is the low reliability of the protection of insulators, because there is not enough space on the traverse of the supports to install this device, i.e. the design of the traverse of the supports does not allow this device to be installed directly above the string of insulators.

A device is known for protecting the insulation of overhead power lines from pollution by birds (USSR author's certificate No. 1036893, Е04Н 12/00, 08/23/1983), including strips movably mounted on the traverse, a sleeve mounted for rotation on an axis attached to the traverse, and strips made U-shaped or T-shaped, rigidly attached to the sleeve and installed symmetrically around its perimeter.

A disadvantage of the analogue is the low reliability of the device to prevent birds from landing on a support.

A known section of an overhead power transmission line (RF patent No. 2081491, H02G 7/00, 10.06.1997) containing a support with a traverse, pin insulators with wires attached to them and protective insulating devices in the form of a comb with a horizontal rod attached to a vertical beam, equipped with a catcher bracket located below the comb, and a comb with straight teeth is located at an angle of 30-45 ° to the horizontal. This arrangement of the "comb" allows you to prevent the landing of birds on it and, accordingly, to avoid contamination of the insulator.

The disadvantage of the analogue is limited functionality, because this invention is intended to protect the pin insulators and is not suitable for protecting the supporting strings.

The closest in technical essence and the achieved result to the claimed utility model is a device for preventing birds from landing on the supports of overhead power lines (RF patent No. 2393603, H02G 1/02, 06/27/2010), containing repelling elements made in the form of a bundle of elastic rods, supports rigidly fixed on the traverses, equipped with two bushings, segments of a flexible cable and a stepped rod, while the elastic rods are made of polymer materials or in the form of metal wires crimped from one end, and with of the other, they are fan-shaped and bent relative to the longitudinal axes of the metal wires, a hole for the pressed end of the metal wires is made in the step rod on one side, and on the smaller diameter side the rod is made with a threaded part for fixing the supports on the traverse, the bushings are rigidly fixed perpendicular to the step rod and the segments of the flexible cable are fixed in bushings located symmetrically with respect to the vertical axis of the stepped rod along the yoke in the area between the chains of insulator rows or it is equipped with a stepped rod, at least two rods with restrictive washers and pipes fixed on them, freely dressed on each rod and fixed with restriction of their movement along the longitudinal axis of the rods with washers, while metal wires are crimped from one end, and with the other is fan-shaped and bent relative to the longitudinal axes of the metal wires, in the stepped rod, on one side, a hole is made for the pressed end of the metal wires, and from the side of the smaller diameter, a thread is made for fixing the support on the traverse, the rods are rigidly attached perpendicular to the stepped rod symmetrically from both sides of its vertical axis.

The disadvantages of the analogue are

- design complexity

- significant cost

- significant time for installation of equipment,

- Conclusion for repair of high-voltage lines for a long time for the installation of this device.

The objective of the utility model is to increase the reliability of protection of insulators, reduce material costs, by reducing damage from lack of electricity to consumers and operating costs.

The technical result is expressed in simplifying the design, reducing the time it takes to install the device to prevent birds from landing on the cross beams, and reducing the time it takes to repair high-voltage lines.

The problem is solved, and the technical result is achieved by the fact that in the device for preventing birds from landing on the supports of overhead power lines containing repelling elements made in the form of a bundle of elastic metal wires, according to the utility model, the repelling elements are made in the form of a piece of a lightning protection cable, one end which is pressed into the sleeve, the internal threaded part of which corresponds to the thread of the mounting unit of the supporting garlands of insulators, and the other end is braided in the form of a whisk, moreover, the device is mounted on a traverse on the attachment node of the supporting garland of insulators directly above the garland of insulators.

The fastening of the device to prevent birds from landing on the supports of overhead power transmission lines on the traverse on the mounting unit of the supporting garland of insulators (KGP), directly above the garland of insulators, provides reliable protection of insulators from death of birds and bird droppings.

The essence of the utility model is illustrated by drawings. Figure 1 shows a device for preventing birds from landing on the supports of overhead power lines. In Fig.2 - the mounting unit of the supporting garland of insulators with an earring, Fig.3 - the mounting unit of the supporting garland of insulators with a bracket. Figure 4 - mounting unit of the device to prevent birds from landing on the supports of overhead power lines supporting garlands with a bracket on the traverse.

A device for preventing birds from landing on the supports of overhead power lines contains a sleeve 1 (Fig. 1) with an internal threaded part 2 corresponding to the thread of the mount of the supporting garland of insulators (KGP). The threaded part 2 is selected taking into account the threaded part of the mounted attachment unit of the supporting string of insulators. A piece of a lightning protection cable 3 is pressed into the sleeve 1 at one end, the other end of which is braided in the form of a corolla (the wires of the lightning protection cable 3 are bent evenly across the sphere in different directions at an angle of up to 45 °) and acts as a repelling element.

The attachment point of the supporting garland of insulators 4 has an earring 5 (FIG. 2) or a bracket 6 (FIG. 3) to which a supporting garland of insulators is suspended. The attachment point of the supporting garland of insulators 4 is installed on the traverse 7 (figure 4).

The device operates as follows. The device for preventing birds from landing on the supports of overhead power lines in the transport position is conveniently delivered to the installation site. Then, the device for preventing birds from landing on the supports of overhead power lines is twisted on the KGP to protect the insulation from pollution and prevent bird nesting, after which the inventive device is put into working position by unwinding the wires of the lightning protection cable 3. Thin elastic wires bent uniformly bent around the sphere in different directions under at an angle of up to 45 °, they do not allow the birds to sit on the traverse and repel them with their oscillating movements.

So, the claimed utility model allows to increase the reliability of the protection of insulators, reduce material costs, by reducing damage from lack of electricity to consumers and operating costs.

In addition, the inventive utility model allows to simplify the design, reduce the time it takes to install a device to prevent birds from landing on traverses, to reduce the time it takes to repair high-voltage lines and to reduce the number of emergency shutdowns of overhead lines.

The advantage of this design is the possibility of installing a device to prevent birds from landing on the supports of overhead power lines not only on the KGP to protect the insulation from pollution, but also on the traverses, as well as directly in the trunks of metal supports to prevent bird nesting and their death.
