Abstract

The invention relates to the construction of power line poles. The aim of the invention is to increase the effectiveness of protection by exposing the bird to electric discharge. The device includes repellent elements 5 mounted on a traverse with a wire of insulators and wires. The frightening elements 5 are provided with flags 6 with a mounting hole 7 into which the hook 8 of the isolating rod 9 is inserted when the devices are mounted on the traverse through a permanent magnet 13. Between the permanent magnet 13 and the connecting node of the frightening elements there is an insulating isolating insert 10, and the ends of the scaring elements are interconnected. The angle between the central and adjacent repellent elements is 20-3 silt. (/ 0vs.2

Description

The invention relates to the construction and operation of prototype distribution devices and overhead transmission lines (VL) of power transmission and can be used on existing VL without disconnecting them.

The purpose of the invention is to increase the efficiency by a protective way of influencing a bird by electrical discharge. FIG. 1 shows a device located on the support traverse, general view; in fig. 2 is a device, a general view of J in FIG. 3 - insulating insert, for example, in the form of an insulator type TF-2 or TF-3, a variant of execution.

The device is installed on the metal cross member 1 of the support 2 overhead lines above the supporting wire of insulators 3, to which the current carrying wire 4 is attached.

The device includes a central and adjacent repellent elements 5 in the form of springs, strips, rods, the free ends of which are equipped with plastic flags 6 blue. The central element flag has a mounting hole 7 into which the hook 8 of the insulating rod 9 is inserted when the device is mounted on the cross arm. In the connecting assembly, the scaring elements are in contact with each other and secured on the insulating insert 10, which is tightly mounted on the pin 11, welded to the bottom of the steel cage 12, inside which there is a permanent magnet 13.

Isolation box 10 may be

It is made of fiberglass, vinyl plastic And-, other materials. Porcelain or glass insulators, such as a car candle, insulators for overhead communication lines, or low-voltage power lines such as TF-2, TF-3, TF-20, HC-16, HC-18 or like them. The only criterion of the suitability of the use of an insulator for this purpose is the possibility of placing a steel cage with a permanent magnet in its cavity. If necessary, the inner skirt of the insulator can be chipped. The use of such insulators as an insulating insert is preferable, since the manufacturability of the device and its stability on the cross bar increases.

The process of mounting the device on a support is as follows.

The electrician, located at a safe distance from the VL wire (on a support or a car lift basket), inserts a hook 8 of the insulating rod 9 into the mounting hole 7 (if necessary, pre-applied a layer of glue on the surface of the stand in contact with the support) and the bar 9 brings the device to the place of its installation. . .

When the device stand touches the steel cross bar, the device is tacked to the cross bar by the magnetic field force of both poles of the permanent magnet. As a result, there is a process of tightening the parts fastened together (device supports and support beams) with subsequent additional fixing them by gluing. After tacking, the hook of the bar is removed from the hole and the bar is removed. g.

The principle of operation of the device is as follows.

The primary deterring factor is the mechanical oscillations of the flags, which the bird perceives visually. The secondary deterrent factor is the electrofiber factor, i.e. the impact on the bird's body of an electrical discharge when it touches the electrode (a scaring element) that is under induced voltage in relation to grounded parts, such as a metal traverse. The induced voltage arises as a result of exposure to an electromagnetic field, which is under the operating voltage of an overhead line wire.

Obtaining the magnitude of the induced voltage. 2, the OKB is achieved by the electrical contact of the repellent elements at one end and in their rh-shaped arrangement at the angle

between the axes of the order of 30 .. The angle is proportional to the magnitude of the induced voltage. At an angle of 20-60, the voltage varies between 1-3 kV. Increase angle over 60

It is impractical because the interaction of the repellent elements is impaired. When swinging one of the elements by the wind (flags are located in different vertical

planes) the other two also begin to unwind. Thus, the boundary values of the angles are determined by the minimum effective and maximum allowable values of the scaring voltage.

The stated voltage values are given for the electrical installation class of .110 kV. For the installation of other voltage classes, a slight adjustment of the device parameters, which is based on the experimental data, is possible.
