    This invention relates to closed high-voltage switchgear. The goal is to increase reliability by reducing the mechanical stresses resulting from temperature linear expansions. The device comprises a busbar system consisting of sections 2 and 3 of busbar housings with two parallel axes. At the ends of sections 2 and 3 there are connecting bodies 4, each of which has parallel sections 2 and 3 branch pipes 5 and 6 connected by a perpendicular branch pipe 7, to which branch bodies 8 of switchgear chambers adjoin. Between section 2 and the nozzle 5 of the connecting body 4, a compensator 9 is installed, from the outer flanges of which there are pulls of the puff 10, which overlap them and the nozzle 5 of the connecting body. Thus, the compensators 9 perceive only linear extensions of the area 2 or 3. The fixed installation of the housings 4 forms the points of support, the load of which is the same and corresponds to the total elastic force of the compensators 9. 3 hp f-ly, 16 ill.

    This invention relates to close-to-high-voltage distribution devices.
    The purpose of the invention is to increase reliability by reducing the mechanical stresses resulting from temperature linear expansions.
    FIGS. 1-5 schematically show the phase of the busbar system and the connecting bodies, a general view; figure 6 - three phases, side view; in fig. - various ways of connecting the branch distributor cells, both schematically and in general, due to which different positions of busbar sections are obtained (identical parts have the same digital designation).
    Fig. 1 shows one phase of a busbar system of a closed high voltage switchgear with gas insulation, which consists of sections 2 and 3 of busbar housings with two parallel axes. At the ends of these sections 2 and 3 there are interconnecting housings 4, which connect the sections 2 and 3 of the enclosures with two parallel longitudinal axes. Each connecting casing 4 has a branch pipe 5, which is located on the central axis of section 2, and a parallel pipe 6 , the longitudinal axis of which corresponds to the longitudinal axis of section 3, Nozzles 5 and 6 are connected by a perpendicular nozzle 7, To the nozzle 7 are adjacent in the middle of the housing 8 Kat-sep switchgear ..
    At one end of section 2, compensators 9 are installed at the connecting flanges of the nozzle 5 of the connecting body 4, the compensators 9 and the nozzle 5 of the connecting body 4 are overlapped with plugs 10, which extend from the outer flanges of the compensators 9 At one end of the 3 side The housing 4 is also equipped with compensators 9, which are also overlapping; pins 10 These compensators 9 can perceive longitudinal expansion, sections 2 and 3 5 caused by temperature changes. Since two compensators 9 are connected to the Xcg plot 2 or 3, respectively, and the 2 to 3 sections have an equal
    length, compensators 9 can have the same design. The length of the plugs 10 is small. Thus, it is not unpredictable what the total length of one phase of the 1S busbar system is because the compensators need to perceive only a linear expansion of section 2 or 3, respectively.
    is small and their loading as well as loading on the fasteners 10, since the connectors 4 are installed fixed in space and thus form the points of the load of all the points
    the supports are the same and correspond to the forces obtained by adding the elastic moduli of the compensators 9 "With the average position of the point I1 of the branch of the branch of the branch S, forming
    the same phase of the distribution cells (fig.O e get shown in fig about 7 the location of the longitudinal axis 12 of section 2 and the longitudinal axis 3 of the section 3 of the busbar system 1 relative to the axis 14 of the transverse nozzle 7 of the connecting body 4 and the axis 5 of the branch 8 and 8. The arrangement of sections 2.2, 2 and j3 of separate phases is shown.
    relative to each other, the branches of the R phase of the distribution chamber are designated by the numbers 16 and the phases T - 17
    Figure 2 shows the connecting body 4 between the Stations 2 and 3 of the R phase of the busbar system 1 are distributed

In addition, under the connecting flange to the chassis 2, you are 40 complete as a compressive and arc-resistant insulator 8, as well as a subconnector, flange between section 3 and the nozzle 6 of the connecting body 4. Another compressive and arc-resistant insulator-18 is located in the cross-beam, “Due to this, two interwave spaces 19 and 20 appear in the connection housing 4, as a result of which

    Connection of the electric arc casing 4 it will damage only one outgoing section of busbar 2 or 3 ,. The ria of which is necessary will be carried out by a corresponding repair j and in the second section of the busbar there will be no need to carry out repair works,
    ; 1a fig.Z and 4 shows a system of busbars 15 which has a length from j
    Plots 2 and 3, which are located respectively between two branches of 8 distribution chambers, are relatively large. On fig.Z are rigidly established not only
    body, but in the middle of section 2 or 3 there is another point 21 of the support. In the example of FIG. 4, instead of a similar support point 21 in one of the two connecting housings, there is a restriction stop 22 for movement of the compensators 9, which limits the expansion of the compensators 9 within acceptable limits and is made in the form of stop surfaces on the specified connecting body and rod with an emphasis fixed on the outer flange of the compensator connected to the section of busbars. The distance between the two common-mode branches of the 8 distribution chambers of the modular EftiH 1 system is of such a magnitude that the linear changes cannot be perceived with ordinary temperature differences with only four compensators. A similar example of performance is shown in FIG. The length of sections 2 and 3 of the busbar system 1 located between two adjacent branches 8 is chosen such that several sections are provided between the two branches 8, in this case three sections 2 and 3. These sections are also connected to each other by connecting housings 4 with compensators 9 located next to them, which are overlapped with knobs 10. Connecting bodies 4, which are not connected to branch 8, are fixed in space and form points of support along the busbar system 1, as well as between branches 8, which, like the connecting housing 4 connected to them, are fixedly mounted. The length of the individual sections 2 or 3 of busbar systems 1 with parallel longitudinal lines can be selected, depending on the desired size, by a compensator 9, which can take all possible linear expansions regardless of the distance between adjacent branches 8.
    The different position of the branch points 11 from the distribution cells relative to the longitudinal axes 12 and 13 of the sections 2,2 j 2 and 3, 3, 3 of the three phases P, 35T of the busbar system 1 while

    It is shown in FIGS. 7-16 schematically and as a general view of distribution chambers. These execution chambers show that the division of the R, S, T phases of the modular pshn 1 system into sections 2 and 3 with different longitudinal axes 12 and 13 of the buildings parallel to each other does not cause a significant increase in the space they occupy. Moreover, all sections of busbars 2, 3 may be located in a space covered by a distribution chamber.
    Figures 7 and 8 show a cable connection chamber 23 with a single busbar system I, which is divided into two sections 2 and 3. In this case, the branch bodies 8 are connected by means of a flange in the middle to the transverse branch pipe 7 of the connecting body 4.
    If, in contrast, branch 8 of the same connection chamber of cable 23 (FIGS. 9 and 10) is connected via a flange to a part of the connection housing 4 located in the direction of the longitudinal axis 13 of section 3, then even two parallel assembly systems can be placed in the same space tires 1.1.
    Figs 12, 14 and 16 show an overhead line connection chamber 24, in which one section 2.2, 2 of busbar systems is connected via a branch point 11 with a branch 8, the casing of which is connected via a flange to a part of the connecting part located on the longitudinal axis 12 housing, as well as with a power switch 25. The next branch 8 is flanged connected to a part of the section 3.3, 3 located on the longitudinal axis 13 and forms connecting elements for connecting the aerial line 26.
    The axes of the branches 15, 15 can deviate from these distribution chambers 24 in different directions, due to which different mutual position of the 2.3 fsz R, S, T sections of the busbar system 1 takes place. FIGS. 11 and 12 show axes parallel to each other 15, 15 branches 8,8, which are perpendicular to the plane formed by the longitudinal axes 12 and 13 of the sections. FIG. 13 and 14, an axis 15 of the branch is perpendicular to the longitudinal axis 12 and 13

    plots and the branch axis 15 passes through the extension of the axis 14 of the transverse nozzle 7 of the connecting body 4. In the examples of execution according to FIGS. 15 and 16, both axes 15 and 15 of the branch lie on the extension of the axis 14 of the transverse nozzle of the connecting body 4.
