Definitions

  • a further preferred embodiment of the invention in particular in the case of electrical switching devices for high rated switching powers, provides for the main contact point to be in the form of a double contact point, a first and a second main contact point being connected in series with one another and each interacting with an arc-quenching device.
  • the current limiting device 28 is provided as a dynamically opening contact arrangement in which, as a result of an electrodynamic lifting force resulting from a current conducted in the secondary current path 26, the movable contact piece (not shown here) of the dynamically opening contact arrangement of the current limiting device 28 lifts so far that the desired current limitation is caused by the switching arc that arises results.
  • FIG. 3 shows a switching device 50 which has a main current path 52 with a magnetic release 54 and a thermal release 56.
  • the magnetic release 54 as well as the thermal release 56 are operatively connected to a downstream main contact point 58, which is also arranged in the main current path 52 and is equipped as a double contact point with a first main contact point 581 and a second main contact point 582.
  • the main current path 52 leads from an access terminal 60 to an outgoing terminal 61.
  • the lower arc guide rails 651, 652 each belong to a secondary current path 66, which is formed from a first section 661 and a second section 662.
  • a current limiting device 68 In the first section 661 of the secondary current path 66, which extends from the access terminal 60, there is a current limiting device 68, which is also provided as a dynamically opening contact arrangement.
  • the secondary current path 66 leads from the current limiting device 68 directly to the lower arc guide rail 651 of the arc extinguishing device 621 of the first main contact point 581.
  • the second lower arc guide rail 652, which belongs to the arc extinguishing device 622 of the second main contact point 582, is connected to the second section 662 of the secondary current path 66, which leads to the Output terminal 61 leads.
  • an insulating partition 583 is used, which separates the two brackets 64 from one another.
  • An insulating partition 783 is used for the electrical insulation of the two arc extinguishing devices 821 and 822 and separates the two quenching plate packs 84 from one another.
  • the arc voltage generated here supports the short-circuit current limitation of the arc quenching chambers shown in FIGS. 1 to 4 (22, 42, 621, 622, 821, 822). If the repulsive force falls below the spring force due to the falling current, the movable contact 96 closes again.
