Definitions

  • the invention relates to a multi-pole electrical circuit breaker according to the preamble of claim 1.
  • Such a circuit breaker is known for example from DE-A-20 17 836. None is said there about the technical design of the mounting rail for the required rigidity.
  • a support frame for high-voltage switches which consists of several bent sheet metal profiles, which are connected by means of screw connections to form a support profile and are reinforced by additional stiffening plates.
  • U-shaped rail made of sheet metal which has a longitudinal joint for magnetic insulation and is reinforced by another sheet and possibly concrete.
  • the present invention seeks to provide a multi-pole electrical circuit breaker to equip a mounting rail that is simple and economical to manufacture and on which the pole columns can be easily and securely attached.
  • the pole columns should also be easily accessible in the area of the mounting rail.
  • the mounting rail can be manufactured quickly, easily and precisely from a flat sheet metal on a known folding device.
  • the openings for screw fastenings and for the pole columns can be made in the sheet before folding, for example by punching or plasma cutting.
  • the manufacture of the mounting rail is very cost-effective due to the simple folding process.
  • Support bearings for the pole columns can advantageously be arranged on the side of the support rail facing the support insulators.
  • the pole columns even if they are mounted on the mounting rail, are easily accessible from above and below for installation purposes. Due to the open profile shape of the mounting rail, the area of the pole columns below the mounting rail is easily accessible.
  • connection of the part passing through the mounting rail the pole columns with the free ends of the legs of the mounting rail can be realized by screwing or a welded connection. It can prove to be advantageous to connect the part of the pole column to the free ends of the legs of the mounting rail by means of stable metallic webs or sheets. The connection becomes particularly stable when the free ends of the legs of the mounting rail are screwed directly to the pole column.
  • the mounting rail 1 has two free legs 2, 3 which, after the sheet metal has been bent, protrude at right angles from the side 4 of the mounting rail 1 facing the support insulators and point with their free ends 5, 6 to the side facing away from the support insulators 13.
  • the free ends 5, 6 are bent inwards again by folding.
  • the support rail 1 thus forms a channel for receiving those parts of the pole columns 7 which protrude through openings 8, 9, 10 on the side 4 of the support rail 1 facing the support insulators 13.
  • the free, bent ends 5, 6 of the legs 2, 3 of the mounting rail 1 are connected to the pole columns 7 via plates 11, 12. This results in greater rigidity of the mounting rail 1 against twisting and bending.
  • the pole columns 7 are fastened to the side 4 of the mounting rail 1 facing the support insulators 13 by screws.
  • the holes for the screws are already in the sheet metal of the mounting rail 1 before they are folded and are introduced either by punching, plasma cutting, milling or drilling, as are the openings for the pole columns 7.
  • the free ends 5, 6 of the legs 2, 3 of the mounting rail 1 can be of such a length that they can be connected directly and without connecting plates 11, 12 to the pole columns 7 via screw connections. This facilitates the assembly of the switchgear.
  • the typical sheet thickness for the mounting rail 1 is approximately 6 to 8 mm.
