Definitions

  • the invention relates to a gas-insulated switchgear assembly with a gas-filled container and a multi-pole vacuum switch arranged in the container with the horizontal position of its vacuum interrupters and with a multi-pole three-position switch disconnector arranged with the horizontal position of its switch shaft below the vacuum switch and drive devices for the vacuum switch arranged on a front wall of the container and the load-break switch, furthermore with feedthrough bushings arranged below the load-break switch on the front wall.
  • a switchgear of this type has become known from DE-A-39 15 948. This arrangement provides favorable conditions for making the electrical connections between the vacuum switch and the load break switch. Likewise, the busbars can be conveniently installed, which enter and exit on the side walls of the container and can therefore be inserted directly into adjoining switch panels.
  • vacuum interrupters are arranged with longitudinal axes oriented at right angles to the front wall of the container and that the switch-disconnector is arranged with an axis of rotation that is likewise horizontal, but aligned parallel to the front wall of the container.
  • busbar bushings in the side walls of the container can be dispensed with without disadvantage.
  • These bushings can also be arranged on the front wall of the container and connected to the switch disconnector without crossing.
  • the containers of a multi-panel switchgear can then be set up next to one another without lateral spacing, the busbars being able to be laid in a suitable manner in front of the containers and being adaptable if necessary.
  • the load-break switch can be actuated by an inner pivoting lever which interacts with its switch shaft and which, on its end facing the front wall of the container, engages an outer, has a fork opening against the front wall, sealed gas-tight.
  • FIG. 1 shows a section of a medium-voltage switchgear with a vacuum circuit breaker and a three-position switch-disconnector, as well as the associated drive devices and the electrical feedthroughs.
  • FIG. 2 shows the side-by-side arrangement of three vacuum interrupters of the vacuum circuit breaker according to FIG. 1. Only the middle of three upper insulating plates is shown to make the parts underneath visible.
  • the control panel 1 shown in the figures has a closed container 2 made of sheet steel, which comprises a vacuum circuit breaker, designated as a whole as 3, with a drive device 4 and a three-position switch disconnector 5 with an associated further drive device 6.
  • the container 2 is grounded during operation and contains a suitable insulating gas, for example sulfur hexafluoride (SF6).
  • SF6 sulfur hexafluoride
  • the vacuum circuit breaker 3 has a three-pole design and accordingly has three vacuum interrupters 12, which can each be actuated by the drive device 4 for switching on and off by means of a coupling device 14 constructed in a straight line and passing through a front wall 13 of the container 1.
  • the three vacuum interrupters 12 lie next to one another with a horizontal longitudinal axis and are fastened between insulating plates in a manner still to be explained.
  • the load break switch 5 arranged below the vacuum circuit breaker 3 is arranged with an axis of rotation running parallel to the front wall 13 of the container 2.
  • the three poles of the load-break switch 5 are therefore one behind the other in FIG. 1, as are the three vacuum interrupters 12. Therefore, the connections between the two switches can be easily made without crossing busbars 15 provided for this purpose.
  • feeder busbars 16 are laid vertically between the bushings 11 and the vacuum interrupters 12 without crossing.
  • the bushings 11 are arranged in steps in height in order to facilitate the connection of busbars.
  • the busbars can be connected from the front without having to have access to the interior of the container.
  • each vacuum interrupter 12 is assigned an upper insulating plate 17, which are fastened to angular holding members 20.
  • the holding members 20 are attached to the front wall 13 and an opposite rear wall 21 of the container 2.
  • a rear carrier 22 and a front carrier 23 are connected to each upper insulating plate 17, between which the vacuum interrupter is arranged.
  • Insulating plate 17 with the brackets 22 and 23 and the vacuum interrupter 12 form a non-functional, but mechanically coherent and mountable unit which, as long as the container 2 is still open, can be easily hung and fastened to the holding members 20.
  • Another component of the circuit breaker 3 are two lower insulating plates 24 and 25 which extend transversely to the upper insulating plates 17 and which, like this, are fastened to holding members 26 which in turn are fastened to the walls of the container 2.
  • the insulating plate 24 is common for the rear ends of the vacuum interrupters 12 connected to the carriers 22, while the insulating plate 25 is common for the front ends of the vacuum interrupters 12 connected to the carriers 23.
  • This arrangement of the insulating plates 17, 24 and 25 leads to a good stiffening against the high forces which short-circuit currents can cause due to the relatively small distances between the vacuum interrupters in the insulating gas, while at the same time the circulation of the insulating gas in the container 2 in the region of the vacuum interrupters 12 is less hindered than when using a single lower insulating plate.
  • the lower holding members 26 are expediently attached to opposite side walls 28 and 29 of the container 2. If a common lower insulating plate is used instead of the individual lower insulating plates 24 and 25, a different arrangement of the holding members 26 is also possible, for example both on the rear wall 21 and on the side walls 28 and 29. It is also recommended to use one for all vacuum interrupters 12 common lower insulating plate to be dimensioned so that it is just like the lower right Insulating plate 25 does not protrude significantly beyond the connecting device 30 in the direction of the front wall 13, so that the elements of the coupling device 14 are easily accessible from below during assembly and the insulating gas can circulate.
  • connecting rails 27 are provided, which are led out through openings in the lower insulating plates 24 and connected there to the busbars 16.
  • the front lower insulating plates 25 each carry a connection device 30 for the busbars 15 and a flexible current band 31, which establishes the electrical connection with the movable connecting bolt 32 of the vacuum interrupter 12.
  • each of the vacuum interrupters 12 is connected to the drive device 4 by a coupling device 14.
  • a clamping device 33, an insulating body 34 and an actuating rod 35 in connection with a bellows 36 are provided as components of the coupling device 14.
  • the bellows 36 is fastened at one end in the front wall 13 of the container 2 and at its opposite end, which projects into the container 2, is connected to the actuating rod 35.
  • a lever gear 37 is connected to the end of the actuating rod 35 which is accessible on the outside of the container 2 and to which a tension spring 40 serving as a contact force spring and as an opening spring belongs.
  • the lever mechanism can preferably have the structure described in DE-A-34 14 016.
  • the lever gears 37 corresponding to the number of poles are acted upon by the drive device 4 with a driving force in a known manner in order to switch on the vacuum interrupters.
  • the drive device 4 is unlatched, whereupon the tension spring 40 acts as a switch-off spring and can switch off the vacuum interrupters 12 against the gas pressure existing in the container.
  • control panel 1 includes a three-position switch-disconnector 5, for example of the type according to DE-C-33 04 272.
  • the circuit-breaker 3 and the load-break switch 5 can be selected in particular in accordance with DE-A-39 15 949 be able to control short-circuit currents without interlocking the circuit breaker and the load break switch.
  • a common for all poles of the load break switch 5 switch shaft 41 is arranged horizontally and parallel to the front wall 13 of the container 2.
  • the drive device 6 for the switch disconnector 5 works with the switch shaft 41 by means of a further coupling device, designated as a whole as 42, which is designed such that the installation of the switch disconnector 5 in the container 2 can be carried out with little effort.
  • the coupling device 42 as is known per se, has a bellows 43, which is fastened with one end in a gas-tight manner in the front wall 13 of the container 2.
  • the bellows 43 is not used to initiate a linear movement, but rather a pivoting movement.
  • an outer pivot lever 44 the pivot bearing of which is arranged approximately in the plane of the front wall 13.
  • a driver bolt 45 for a fork opening 46 of an inner pivot lever 47 which is mounted approximately centrally on a bearing bolt 50.
  • a reversing gear 51 the switch shaft 41.
  • the inner pivot lever 47 and the deflecting gear 51 are expediently attached to the load-break switch 5 in such a way that this unit can be coupled to the outer pivot lever 44 and thus to the drive device 6 for the load-break switch 5 by simply sliding the fork opening 46 onto the driving pin 45. Adjustment and adjustment work can largely be dispensed with.
