    (54) DISTRIBUTION FOR THE WIRES OF THE SPLITTED PHASE OF THE AIR TRANSMISSION LINE
    one
    The invention relates to power engineering.
    A known spacer for the wires of the split phase of an overhead transmission line, comprising a hollow detachable body made of two interconnected elements of rigid material, hinged 10 clamp levers on the number of wires of the split phase, the axes of rotation of which are perpendicular to the plane of the body components, made with slots on the inner surfaces in which the axes for fastening the clamping levers are located using elastic sleeves serving to absorb energy and holding the clamping levers in the neutral position, each of the levers being provided with locking elements of two parts 1. However, this strut does not include mechanical damage to the wires fixed in it.
    The aim of the invention is to prevent mechanical damage to the wires.
    This goal has been achieved in a spacer for wires of a split phase overhead power line, containing
    A hollow detachable housing made of two interconnected elements of a rigid material, hinged on it by the number of wires of the split phase clamping levers, the rotation axes of which are perpendicular to the plane of connection of the housing elements made with slots on the inner surfaces in which axles for fastening the clamping levers using elastic sleeves, which serve to absorb energy and hold the clamping levers in the neutral position, each of the levers being provided with lugs by many elements of two parts.
    New in this strut is that the body elements r1 are made in the form of shells with smoothly bent walls, edges tightly adjacent to each other along the cavity of the body connector, with the end surface of elastic bushings and the surfaces of the shells and levers contacting with the end surfaces elastic sleeves, made with protrusions and depressions, such as gofrs1mi. In the spacer, according to the invention, the shells can be made of light metal castings, in particular, aluminum.
    Elastic sleeves may be made of semiconducting material, in particular of semiconducting oliisoprene.
    In the spacer according to the invention, one of the parts of the clamping element can be an aluminum casting, and the other can be made in the form of an elastic steel plate.
    FIG. Figure 1 shows a proposed spacer for two wires of a split phase with all parts included in the spacer; in fig. 2 - the same with a partial section; in fig. 3 is a section according to A-A of FIG. 2; in fig. 4 is a section according to BB FIG. 2; in fig. 5 - spacer for three wires of the split phase; in fig. 6 - spacer for four wires of the split phase; in fig. 7 and 8 - elastic sleeve, axonometric projection and rear view; in fig. 9 - clamping lever, side view; in fig. 10 - spacer for four wires of the split phase, option; in fig. 11-14 - wired spacers for two, three and four (two variants) wires of the split phase.
    The spacer for the two wires of the split phase (see Figs. 1-4.) Comprises a hollow rigid body consisting of two connected metal shells 1, two clamping levers 2 hinged to the body, and elastic sleeves 3 for energy absorption. made in the form of circular washers frictionally engaged with clamping levers to shift the latter to neutral positions. Each of the shells 1 is an aluminum casting with two horizontal edges 4 and 5, which abut against the respective edges of the other shell when the shells are assembled. The shells are fastened together with the help of bolts 6 and nuts 7. Each of the bolts b connecting the shells and located between them is a hinge axis and is part of the hinge assembly of the respective clamp arm. This pivot axis passes through a cable that is held parallel by a lever. Each clamping lever 2 consists of a rigid clamping element 8, an elastic clamping element 9, and a fixing bolt 10 fastening these elements together.
    Under normal conditions, the bolt 6 does not come into contact with either the rigid clamping element 8 or the elastic sleeve 3. These bolts are intended primarily for connecting the shells and must pass through them and the elastic sleeves 3 without any contact. When bolts are in contact, the spacer will not have longitudinal flexibility, which is necessary in the case of longitudinal wire movements. The actual hinge in the spacer is elastic sleeves 3.
    As shown in FIG. 2 and 9, each pair of clamping elements 8 and 9 is intended to hold one of the two longitudinally extending wires 11 and 12 of the split phase. The hollow rigid body formed by the shells is located across the wires, and the hinge axes, which are the clamping bolts 6, are located in a plane parallel to the common plane of the wires. The rigid clamping member B is an aluminum casting in which a cylindrical hole 13 for a bolt 6 and a threaded hole 14 for a fastening bolt 10 is made. The latter has a threaded part 15 equipped with a nylon gasket, therefore, to rotate the bolt a positive torque is required.
    5 moment, even if the bolt is not subject to axial tension. The fastening bolt 10 is fastened in the desired position by caulking its end.
    The elastic clamping element 9 is a sheet steel spring itself, in which you have a bolt-hole opening 10. Oops other element 9 has part 16,
    covering the wire and interacting with the similar part 17 of the rigid clamping element. This constructive implementation provides a uniform clamping force.
    0 The clamping levers 2 are displaced to a neutral position in which they (as shown in Fig. 2) are angled to the common plane of the wires 11 and 12. The neutral positions of the extension levers are preferred when the axis of each lever passes through the center of the clamped wire, and the axis of rotation of the lever is angled from
    l 30 to 60 ° to the total plane of the wires, while the optimal angle of inclination is 4. If the angle of inclination is less than 30®, the transverse vibrations are not sufficiently eliminated (in the case of two wires), and if
     the angle of inclination is greater than bo, the swinging of wires by the action of the wind is not sufficiently eliminated.
    The clamping levers, of course, can rotate around their axes 0 of the bolts 6, while the amount of rotation is limited by the stop edges 18 and 19 formed by holes made in the housing, which include clamping levers, each of these
    5 holes are formed when two vei-mode cuts made in the edges of the shells 1 coincide. Persistent edges 18 and 19 also limit the hinge movement of the levers 2 when the wire bundle is exposed to high forces of mutual attraction caused by a short circuit in the transmission system. These forces can be quite large if they are not adjusted accordingly, they will lead to the destruction of the elastic sleeves. Elastic, energy-absorbing sleeves, displacing clamping levers in their neutral positions, are embedded in the hinge assemblies of the levers. They are made of semiconductor polymer material.
    The sleeves 3 of each pair are mounted on one clamping bolt b and are located between the opposite surfaces of the clamping lever and the adjacent surface of the shell, located around the hinge joint, thereby preventing the contacting of said surfaces during operation. The planes of the sleeves are made with protrusions and depressions, such as corrugations 20, which are in contact with the corrugations 21 on the corresponding surface of the shell 1 and with the corrugations 22 located on the corresponding surface of the clamping lever 2.
    Each bushing is subjected to axial compression between the opposite surfaces with which it interacts. It is of sufficient thickness, which ensures compressibility and eliminates the adhesion of the planes of the washer with the interacting surfaces of the clamping lever and the shell. When the clamping lever is rotated, the sleeve is subjected to a twisting voltage and tries to return the lever to its neutral position. Therefore, depending on the ability of the sleeves to dissipate energy, the energy of vibration, caused by transverse vibrations and / or swaying of the wires by the wind, such vibrations are also absorbed. In addition, the bushes, due to their elasticity in the axial direction, are designed to absorb and dissipate the vibration energy caused by the differential vibrational movement of the wires in the axial direction.
    Recently, elastic sleeves of this type have been made from natural rubber or silicone rubber. Natural rubber, although it is a satisfactory material at moderate temperatures, has good properties at low temperatures. In addition, natural rubber is sensitive to
    ozone action. Due to the fact that polyisoprene is produced by artificial means, its characteristics such as tensile strength, tear resistance and wear resistance, -. e can be improved. Natural rubber, however, must be chosen with great care in order to obtain the same characteristics and properties.
    Silicone rubber on the other hand has good resilience.
    10 at low temperature and resistance to ozone, but at the same time relatively poor wear resistance. Natural rubber and silicone rubber are mixed to obtain
    5 of a semiconducting substance, but their physical properties, which are required to obtain elastic sleeves, significantly deteriorate. Therefore, a silicone rubber sleeve is used in the non-conductive state. The tensile strength and fracture of polyisoprene is significantly better than that of a good mixed silicone rubber. However silicone
    5, the rubber is sufficiently deformed when subjected to a periodic twisting deformation, being in a compressed state. This phenomenon is absent when used.
    0 polyisoprene compounds. The need to use auxiliary elements to provide a current leakage path is a serious disadvantage; metal springs
    - may break prematurely, and semiconductor sleeves tend to lubricate the metal surfaces with which they interact.
    0 According to the invention, elastic sleeves are preferably made of semiconducting polyisoprene.
    The spacer for the three wires of the split phase has a triangular shape body consisting of two shells. The housing is arranged in a vertical plane, perpendicular to the wires.
    Spacer body (see Fig. 6),
    The Q for the four wires of the split phase is made in the form of a square frame, which is also located in a vertical plane, perpendicular to the wires. Spacer body designed for four-to-eight split-phase wires
    (Fig. 10), is made in the form of a trapezoidal frame, at the ends of one diagonal of which clamping levers 23 and 24 are fixed, intended for
    0 gripping two wires (not shown) lying in a common vertical plane, and clamping levers fixed at the ends of the other dichgonal .25 and 26, which serve to grip the other pair
    5. Wires located in a common horizontal plane. It should be noted that the clamping levers 23 and 24 are inclined at an approximately 45 angle of the vertical plane, and the clamping levers 25 and 26 are inclined under the glom 45 ° to the horizontal plane (the levers are shown in neutral positions). .
    The interaction of the struts in the phase with the wires 11 and 12 is represented in FIG. 11 .. In this case, the spacer body. (or shells 1) is located below the horizontal plane passing through the longitudinal axes of the wires 11 and 12. The thrust surfaces of the edges of the shells 1 are arranged in the transverse vertical plane separating the spacer in the longitudinal direction into two symmetrical parts.
    The clamping levers 2 can rotate, depending on the energy absorption property of the elastic sleeves 3, around a horizontal axis that coincides with the axis of the clamping bolt 6, while the horizontal vibrations of the wires or their swinging under the action of the wind will cause the clamping levers 2 to move in vertical plane. When the clamping levers 2 are in a neutral position, they form an angle of preferably 45 with a horizontal plane (the inclination angle can vary from 30 to 601. When the spacer is installed, it is positioned in a vertical plane, as shown in Fig. 11. Due to the change the physical parameters of the wires and the interaction of the environment (for example, temperature fluctuations) there will be a differential longitudinal movement of the wires, shown by arrows 27 and 28. This movement may cause a torsional formation of the moment acting on the spacer and absorbed by the elastic sleeves 3. The elastic sleeves are installed with sufficient compression so that the forces acting on the sleeve due to differential longitudinal movement will not lead to any of the parts of the sleeve from the state of compression and therefore the twisting moment will not affect the correct operation of the struts.

    The spreader used for the three wires 11, 12 and 29 of the split phase (Fig. 12) may have a housing in the form of a triangular frame, arranged in the vertical plane nep-t pendicularly to the wires. The movement of the clamping levers 2 under the action of vibration of the wires occurs around the central axis of the clamping bolt 6 and in the vertical plane. Dolit the axis of the wires 11 and 12 are located-,
    8 horizontal planes, while wire 29 runs below and parallel to wires 11 and 12. Clamping levers 2 are inclined to the common horizontal plane of wires 11 and 12. The angle of inclination formed by the axis of each clamping lever in a neutral position is such that the clamping levers are arranged parallel to the longitudinal axis of the wires 11 and 12. In the considered strut, the twisting moment affects the compression of the elastic sleeves. However, this does not affect the correct operation of the struts. A twisting moment can also occur with a different combination of wire pairs or with the different actions of all three wires relative to each other. .
    The strut shown in FIG. 13 is intended for four wires of a split phase, arranged at the apexes of a square. The body of the shells 1 is made in the form of a square, located in a vertical plane. The longitudinal axis of the wires 11 and 12 lie in a horizontal plane. As in the spacer shown in FIG. 12, the axes of the clamping levers 2, passing through the centers of the respective wires and the axis of rotation, are inclined in a neutral position at an angle of 45 ° to the horizontal plane. Twisting moments may act on the frame due to differential longitudinal movement of the wires, as indicated by arrows 27 and 28 for the two wires. However, these forces can occur in all four wires simultaneously.
    The strut shown in FIG. 14 is intended for use with four wires of a split phase located at the vertices of an isosceles trapezium. The diagonal of the isosceles trapezium, passing through the centers of the cross section of the wires 29 and 30, is located in the horizontal plane. The body of this strut has the shape of an isosceles trapezoid. The clamping levers, being in an offset position, form an angle of 45 with the horizontal plane.
