SU483510A1 - High voltage line support - Google Patents

Description

The invention relates to high-voltage transmission lines (HVL) of high voltage, advantageously. 1, naturally, 220-750 kV, n can be used as an intermediate, angle and anchor-angle support. A well-known high-voltage power line is known, including a stand, traverses and elements supporting the stand, for example, heals. The known support due to painful strands in the straps and the considerable distance between the wires suspended from the lower traverse and leading to an increase in the consumption of materials for strands and foundations, has an improved structure. The purpose of the invention is to facilitate the design of the support. high-voltage power lines are made with a shnrengel, simulating on one of the sides of the rack, on the other side of which there are crossheads, the rack being installed at an angle to the horizontal flat sti. FIG. 1-6 illustrate the proposed power pole. The support includes the post 1, the cross member 2 and the elements supporting the post, which is made with a shnrengelem 3 consisting of a cable and a post, and mounted on one side of the post (outer), on the other side of which the cross member 2 is located installed at an angle to the horizontal plane and supported either by a support 4 and two delays 5, 6 located in the plane of the rack (Fig. 1 and 2), or two props 7 and 8 arranged at an angle (Fig. 3 and 4), or three delayed 9, 10 and 11 (Fig. 5 and 6). Hour 1 (Fig. 1-4) rests on a spherical hinge, and Hour 1 (Fig. 5 n 6) rests on a cylindrical hinge. Rack 1 can be made of metal, reinforced concrete or wood. The invention artificially created the predominant direction of the main load, which determines the cross section of the support elements, and selected the prestressing force in the shear, so that the maximum forces in the rack under normal and emergency conditions are approximately the same. Such force control allows the construction to be of equal strength and optimal in terms of material consumption. The oblique arrangement of the rack allows the use of shortened crossheads, and the arrangement of the crossbars in different vertical planes prevents the wires from slipping when the ice is cleared.

Subject invention

A high-voltage power line support comprising a rack, crossbars and elements supporting the rack, characterized in that, in order to facilitate the construction, the support is made with sprengel mounted on one side of the rack, on the other side of which the crossbars are located at an angle to the horizontal plane.
