    A right angle connection for an SF6-insulated high-voltage switch gear with three phase conductors is disclosed. The conductors are arranged in the connection with a straight section and an adjustable crank section. The crank section is adjustable between two positions 180 DEG apart, so that the connection can be used in either direction.

     . ,;
    The present invention relates to a three-phase high-voltage switchgear of a sturdy type with ayu -tiftefistaya sulfur insulation with faee wires located in the corners of an equilateral triangular duct enclosed in a flexible capsule box made up of various parts.
    Integrated gray hexafluoride switchgear (switchgear switchgear) - compared to conventional switchgears, have a working area requirement (only about 10%). Therefore, they are particularly suitable for use in areas with a large amount of electrical energy consumption, for example, in urban areas and industrial centers.
    up to the present, hermes are insulated with hexafluoride sulfur or voltage switchboards; they were assembled with the exception of the bus; single-phase buses (single-phase) During the further development of the switchgear and transforming them into even more compact switching installations, all three phases of the isolated hexafluoride gray high-voltage distribution are being sealed devices.
    High-voltage distribution devices are known for implementing various types of electrical switches. For example, on the ring busbars, which are assembled from separate units such as switchgear. With this, for the manufacture of phase conductor connections, it is advisable to rotate the phase conductor assembly in this unit through an angle of 180 °.
    High-voltage switchgears are also known. They are insulated with sulfur hexafluoride, in which the phase conductors are bent appropriately for this purpose 1.
    However, these partial bends under certain conditions can take on a rather complex (three-dimensional) configuration, so that given the presence of a different surplus of each Lazinogf wire, these measures are relatively uneconomical.
    The purpose of the invention is to simplify the installation and construction of high-voltage
    KRU ..
    The goal is achieved by those. that in a three-phase high-voltage switchgear with hexafluoride isolation ring containing phase wires encased in a sheath and positioned so that their axes form the vertices of an equilateral triangle, with these phase wires enclosed in a sealed enclosure, the sheath of each phase wires is made of two parts one of which forms a rectilinear section of the shell, and the second is made in the shape of a knee, moreover, these parts in the joints are made with the possibility of turning and relative to the other. The straight and knee parts of the casing are connected by means of a flange, and the free ends of these parts are provided with plug contacts. To obtain rotation of the assembly of the phase wires, the knee-shaped parts are easily mastered in production due to their simple forming. All the arcs of these parts lie in the same plane of the bend. To rotate two of the three phase wires, the same parts are applicable in the form of a bend,
    Fig. 1 shows the hermetic package of the proposed high-voltage switchgear with sulfur hexafluoride insulation for phase conductors; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one.
    The device comprises a housing 1 with phase conductors, a disk insulator 2, plug contacts 3 for connecting phase conductors, a linear one, part 4 of the sheath of phase conductors, part 5 and b in the shape of a phase elbow. wires, flanges 7 for connecting shell components, plug contacts 8 for connecting phase wires and screws 9.
    The housing 1 is made with flanges on both ends and is closed at one end with a disk insulator 2. The phase conductors are located in this disk insulator at the corners of an equilateral triangle. The case 1 phase wires, each of which is enclosed in a sheath, is included in the form of an assembly of rectilinear part 4 and part 5 or b in the form of a knee through a flange connection 7, and the rectilinear part serves simultaneously as an input through a disk insulator 2, fixed eaten in it. Flange connection is made so that parts 5 and b have the ability to rotate 180
    Split lines (AIG. 3) of three circles show the initial position of the parts in the shape of a knee, and the three triangle lines show the positions of the parts 5 and b after turning them 180. The wires connected to them (not shown) of the phases also make this turn. Finally, screws 9 tighten the flange assembly. The straight parts, like the knee-shaped parts, are made at their ends in the form of plug contacts 3 and 8 for simple connection to them, connecting wires of different phases to them.
