Definitions

  • the invention relates to a switching device for a consumer to be connected to three phases with at least three switching points.
  • the invention has for its object to provide a switching device of the type mentioned above, which can get by with a simple structure with less volume than the known switching devices of the contact material. This is achieved in a switching device of the above type in a simple manner in that of the three switching points the movable contact part of a switching point lags ahead of those of the other two when switched on and when switched off, that the contact erosion essentially only occurs when the switching capacity is required as required the other two switching points.
  • the time-shifted switching point requires only a very small volume of the expensive contact material. It also does not need to be made of high quality contact material. It can consist of AgNi, which is easy to weld compared to AgCd0. At the end of the electrical service life, only the switching elements of two current paths have to be replaced, which saves costs for spare parts and time for inspection when changing the switching element.
  • the use of the design according to the invention is generally also possible in devices in which certain separation lengths are required in the open state if the opening distances at open switching points correspond to the required separation distances.
  • Another significant material saving, preferably the expensive one Silver can be achieved if one switching point is equipped with at least 70% less contact volume than the other two switching points, or if the arc quenching device of one switching point is only equipped with parts of the quenching device of the other two switching points.
  • the switching device shown in the drawing consists of the housing 1, in which the fixed magnet part 2 with the coil 3 and the fixed contact part pairs 4, 5 and 6 are held and in which the contact bridge support 7 is movably guided connected to the movable magnet part 8.
  • the contact bridge support 7 holds the contact bridges 11, 12 and 13 in window-shaped openings 9, 10. They are pressed via contact pressure springs 14 against stops 15, 16 formed by the edges of the window-shaped openings 9, 10.
  • the stop 16 for the contact bridge 12 is lower than the stops 15 for the contact bridges 11 and 13 by the amount 17 (indicated by the arrow in the drawing), so that the contact bridge 12 comes into contact with the fixed contact parts 5 earlier than the contact bridges 11 and 13 with the fixed contacts 4 and 6.
  • the switching point formed from the contact bridge 12 and the fixed contact part pair 5 leads the contact points of the other two phases.
  • this switching point is the last to open when the switching device is de-energized, so that the actual switching capacity is taken over by the contact bridges 11 and 13 with the fixed contact part pairs 4 and 6.
  • This is expressed by a relatively thin contact pad 18 on the contact bridge 12 or on the fixed contact part pair 5. Since the contact erosion occurs practically only from the current paths formed by the contact bridges 11 and 13 with the fixed contact part pairs 4 and 6 compared to known contactors 3-current paths, the contact material of the 2-current paths is also better utilized.
  • the arc extinguishing device 19 can, deviating from the usual construction with quenching plates, arc guide parts etc., for which a switching point can be significantly reduced.
