Definitions

  • Such a switch is known for example from DE-AS 19.66.973.
  • the drive rod is transverse to the direction of movement of the unit movable contact piece - blow nozzle - pump cylinder.
  • This unit is coupled via a rocker arm to the longer arm of an angle lever which can be pivoted on a fixed pin, the shorter arm of which is coupled to the drive rod via a coupling.
  • the toggle lever, to which the pump piston is coupled, is in the switched-on position in a kink position pointing away from the drive rod, and its knee joint is connected to this drive rod via a further coupling.
  • the drive that drives the drive rod must also perform the following work.
  • the movable contact piece and the components that move with it must be accelerated from a standstill.
  • the opposite movement of the pump piston with respect to the cylinder is in the cylinder right at the beginning Compress existing gas, so that somewhat later compressed quenching gas is available for blowing the switching arc.
  • the proposed gas pressure switch according to the invention is characterized in that the lever mechanism has a first coupling, which is articulated on one end on the knee joint, on the other on the movable contact piece, and a second coupling which is on the one end between the ends of the first coupling on the latter and on the other end on the drive rod is articulated so that at the beginning of the switch-off stroke the kink position of the knee lever is initially reinforced.
