The invention relates to the construction of transmission lines.

The aim of the invention is to simplify manufacture and expand functionality.

FIG. 1 shows the proposed support (single-rack version) for double-chain power transmission lines with outward-turning elements with cross-sections with different-sized branches, a general view; in fig. 2 is a variant of a U-shaped support for double-chain transmission lines; in fig. 3 - the same. with a triangular arrangement of the wires of the line; in fig. 4 - the same, with a mountainous arrangement of wires; on

FIG. 5 is a view A of FIG. 2; in fig. 6 shows the support of FIG. 1 with the suspension of wires in the break of the elements of the crosspiece; Fig. 7 shows a single post support for a double-circuit transmission line with a horizontal arrangement of the crosshead elements, a general view; Fig. 8 is a variant of a double-support rack-mount stand with a horizontal arrangement of the elements of the traverse made of an electrically insulating material; Fig. 9 is a variant of the arrangement of the U-shaped support with the arrangement of the element of the flat plate in horizontal plane and with the tension wires of the insulators of two projections; in fig. 9 is the same, side view, in FIG. 10f the same, frontal projection, in FIG. 1 to 1 is a view of FIG. ten.

The support includes pillars 1 and 2, for example, of pipes and a cross bar 3 of bent elements 3 for wires 4 suspended on insulators 5. The supports of the support are broken up in the transverse direction of the stretch line 6.

Each bent element 3 of the traverse is made with different-sized parallel branches with a curvilinear section bent along the radius. Elements 3 can be connected with each other to form an oval, and they can also be made not closed. They can be placed both vertically and horizontally.

FIG. 1 shows a variant of the arrangement of a double-chain transmission line support from a vertical THIN arrangement of the elements 3 facing outwards (single rack version), and FIG. 2 - the elements 3 are turned inwards, and in this case the racks 1 and 2 form a U-shaped configuration of the support also of a double-chain transmission line.

Wires 4 can be dissected in element 3 either fixed on one insulating suspension-brace 5 along the longitudinal axis of a closed oval (shown by a dotted line in Fig. 1), or by means of transverse suspension-calculating current 5 (Fig. 2). in the case of using unclosed crosshead elements, the end of the longitudinal suspension-brace 5 is fixed with a transverse brace (Fig.).

The use of the open element 3 from below allows to simplify the installation of the line wires, since the wires of all three phases of the line are fixed on the suspension

brace 5 is still on the ground and only then is lifted and secured on a support.

The wires of the phases can be mounted with a triangular arrangement of the line (Fig. 4). Moreover, in the latter case, the third arcuate element is introduced, and their ends are attached to the traverse 7.

Elements 3 can be attached to the rack symmetrically in height with an elongated branch. A flexible insulation traverse in the form of a suspension bracket 5 can be stretched between the ends of the short branches of the elements 3. The middle phase wire is additionally connected to the element 3 by a rod insulator 8 in order to prevent the wires from swaying under the action of wind loads

If it is necessary to increase the rigidity of the support in the plane of the line, each of the uprights 1 and 2 can be made of two parts with a bent basal part in the form of a brace so that a left and a half-right are formed (Fig. 5). Such doubled and reinforced racks can be used, for example, for anchor supports or for supports of double-circuit lines of ultrahigh or ultrahigh voltage. However, these reinforced pillars are assembled from typical unified elements.

The elements of the uprights are interconnected by kerchiefs 9 or a grid binding. Using the gussets 9, the posts 1 and 2 in the supports can be connected (Figs. 1 and 7).

Elements 3 can be installed with a horizontal axis of the oval (Fig 7-9), while the plane of the oval is vertical. The support can be single rack. U-shaped two-post, or three-post, double-circuit. The wires of the 4 chains of lines are fastened by insulating cross braces 5 between the longitudinal branches of the element 3 or the wires are suspended on the wires of insulators to the lower part of the element 3. At the same time, the elements 3 themselves are additionally supported by stretches 10. Elements 3 can be made of electrically insulating material, and the wires 4 are attached to insulating struts 11, which also serve to increase the rigidity and strength of the fastener. In the case of using insulating elements with a vertical arrangement (Fig. 1), the wires 4 are attached to the outer sides of the oval. Element 3 can be installed in a horizontal plane. Such an arrangement of the support beam allows the use of tension wires of insulators 12, and the wires are connected with a train 13. Moreover, to increase the rigidity of the beam, its longitudinal elements are connected by transverse straps 14 (Fig. 1)

The device works as follows.

In the support (Fig. 1), the load from the weight of the line slots is perceived either by a cantilevered cement} i. pa n 1 in the element or in the civiae of the closed kop1 p) the same two interconnected and unaligned elements of the Bpagodar pretvrant i but strained according to the weight of the calculation 5 of the pitching ipo of the pine shaft are working for bending.

At the support (Fig. 2 and 3) or the weight of the wires are perceived by the frame structure. When horizontal elements are mounted (Fig. 7), the wire rolling is minimal because suspension brackets 5 are the shortest and toughest. At the support (Fig. 8) the wires are fixed to wood strut

Expansion of the functional possibilities of the support of the aesthetics using the same and the same elements 3 are mounted on the design of the design and purpose of single-chain double-chain intermediate anchors, with vertical or horizontal alignment of the phase conductors.

The installation of the line is simplified when the wires are fastened on the ground to the flexible traverse (brace) a in are attached to the element 3 and the water is pre-attached to the ground to the ring element and then, together with the ring fastener, is lifted onto the supports
