  • the characterizing features of the main claim that is, in that the six rooms (A1, A2, B1, B2, C, D) are housed in a common housing which forms a control panel, the housing still enclosing an encapsulated pressure relief chamber and the medium voltage rooms (A1, A2, B1, B2, C) so are arranged so that they adjoin either the top of the housing or the pressure relief space.
  • switchgear to be constructed which is considerably more compact than was the case in the prior art, without having to compromise on ease of use and without impairing system safety, even when arcing occurs in one or more of the encapsulated rooms .
  • the two busbar compartments are separated from one another by the exit compartment (C). This increases the safety of the overall arrangement and enables a particularly simple and compact switch carriage or switch insert construction for the switchgear.
  • the two switchgear or slide-in compartments have a common wall area both with the output compartment and with the associated busbar compartment, because then both slide-in mating contacts can be accommodated in a common candle level, and these connections nevertheless in each case different rooms open, which in turn serves to protect against unwanted flashovers.
  • the arrangement becomes particularly user-friendly because it can be viewed and operated from one side if the circuit breaker compartments are arranged vertically one above the other.
  • the pressure relief space will expediently be arranged below the two insertion spaces. This has the advantage that there are particularly short distances for the light arcing hot gases for the rooms

  • the switch panels according to the invention allow the arrangement of several such switch panels to form a switchgear assembly in which the individual pressure relief spaces
  • Switch panels are placed side by side, allows relatively good accessibility from the switchgear side, so that if necessary, flaps opened by an arc can be replaced in a simple manner.

  • the switch panel shown in Fig. 1 is provided for a three-phase busbar, which can be connected accordingly with three discharge cables. If you want to be able to switch from one busbar to another busbar for operational safety reasons, as is practical or even mandatory in many systems, this can be achieved in the construction shown by placing two switch panels according to FIG. 1 back to back, and the output cable running downwards connects in parallel. You can also put two such panels next to each other and feed the busbars from one side, while the output cables are in turn connected to them Exit are connected to each other in phases. However, the required space is doubled. It also becomes difficult to find several of these
