SU744811A1 - Overhead power transmission line - Google Patents

Description

The invention relates to power engineering, in particular to high voltage overhead power lines. The known electrical transmission line with the angle of rotation of the path, containing the current-carrying wires, the wires of the insulators and the node for changing the direction of the line to which two directions of wires are connected through the wires of the insulators, in which at least one group anchor. However, this line has the disadvantage of short spans adjacent to the node for changing the direction of the line of spans, which requires installation on the line close to the angle of rotation of two intermediate supports, providing them with the necessary dimensions of the wires from the ziggle. The closest technical solution is an overhead transmission line with an angle of rotation of the route, containing an angle support with three racks, to each of which wires are connected to one side using wires of insulators attached to the anchors on the opposite side. However, this aerial transmission line is rather sluggish. The aim of the invention is to simplify the construction of the transmission line. This goal was achieved in an overhead transmission line with an angle of rotation of the route containing an angle support with three columns, to each of which wires were connected to one side with a wire of insulators and to the anchors on the opposite side. New in this overhead transmission line is that the angle support is discharged, from separately standing racks located along the bisector of the turn angle of the track, is hinged on the base plates, and the anchors of the two racks inside The base plates of the adjacent racks, while the line is equipped with tami, which connect the anchor of the rack, outer relative to the angle of rotation of the track in series with the foundation glitam} of all racks. The section of the overhead power transmission line with the turn of the route and the corner support with three iTpt racks drew on FIG. 1 in the plan; in fig, the same, side view.

Conductive wires 1 to noi; The tracks LIE-1II 2 after the turn of the line are attached to the bush ndem insulators 3.

Inclined racks 4, located along the bisector of the angle of rotation of the line, pivotally rest on the base plates 5. The upper sections of all the racks are attached to the straps 6, to which are also attached the second ends of the arms of two racks internal to the angle the turn of the track is attached to the base plates 5 of the adjacent racks 4. The stand of the stand 4, outer relative to the angle, of the turn of the track, is connected to the anchor 7, which is connected to all the Foundation plates 5 by steps 8 and 9.

The length of the racks 4 is chosen corresponding to the minimum size of the wires 1 and 2 above the ground, Their length is small; for example, for lines with a voltage of 110 sludge, it is 6-6.5 m.

Hour 4 can be made, for example, for commonly used wires in the case of two 110x8 mm corners, set with a cross. The weight of such a rack is about 150 kg, and the steel consumption of all three racks is about 450 kg. For this example, base plates 5 of size O, 8 ,,., 2 m, laid on the surface of the soil, are sufficient.

Thus, the consumption of materials in Gül e; 1 and Pogorot is very small "
