Definitions

  • the invention relates to a high-voltage circuit breaker according to the preamble of patent claim 1.
  • Such a switch is known from DE-OS 27 41 022, in particular Fig. 8.
  • the extinguishing gas in a closed chamber is essentially heated and compressed by an arc rotating under the action of a magnetic field.
  • the gas pressure in the heating chamber rises sharply and, above a predetermined pressure value, a wall delimiting the heating chamber is moved into a further closed chamber.
  • fresh quenching gas located in this chamber is compressed and then used to extinguish the switching arc.
  • the strength of the extinguishing gas blowing depends on the strength of the current to be switched off.
  • the circuit breaker according to the invention is characterized in that, even when switching weak currents which only cause a relatively small pressure increase, a quenching gas flow which is sufficiently strong to extinguish the switching arc is available. This extinguishing gas flow is also characterized in that it has a relatively large proportion of fresh extinguishing gas in all switching cases.
  • the extinguishing capacity of the high-voltage circuit breaker according to the invention can be effectively improved if the switch is designed in accordance with the features of claim 2.
  • the temperature of the heated extinguishing gases is mixed down particularly favorably by adding fresh extinguishing gas.
  • circuit breaker according to the invention is designed in accordance with the features of claim 4, the drive of the movable contact piece is supported in the drive direction by the heated extinguishing gases.
  • a movable erosion contact piece 1 designed as a nozzle tube, engages with the contact fingers of a fixed erosion contact piece 2 (see left side).
  • annular electrode 3 is arranged below of the fixed erosion contact piece 2, which is electrically conductively connected to one end of a coil 4. The other end of the coil is in electrically conductive connection with the erosion contact piece 2.
  • the coil 4 is attached to an insulating body 5, in which annular spaces 6, 7 and 8 are provided.
  • the annular space 6 is connected to a further annular channel 12 via an annular mouth 9, the annular space 8 via an annular channel 10 and an annular mouth 11.
  • the annular spaces 6 and 7 are connected to one another via an opening 13 provided in a wall 14.
  • the annular spaces 7 and 8 are separated from one another by an annular piston 15.
  • This ring piston 15 is connected via webs 16 to the movable erosion contact piece 1 and is part of a compression device for extinguishing gas, which is provided in all the spaces and channels specified.
  • Check valves 20 are provided on the annular space 8, which prevent a pressure drop in the space 8 when the compression device is actuated, and which enable fresh extinguishing gas to flow in when it is switched on.
  • the heated, high-pressure quenching gas is stored in the annular space 6.
  • Part of the extinguishing gas stored in the annular space 6 passes through the opening 13 into the annular space 7, in which it exerts a force acting on the piston 15 in the switching-off direction and thus supporting the switch drive. This prevents the piston 15 from working against the pressure build-up of the extinguishing gas caused by heating and thus resulting in a deceleration of the drive.
  • the fresh quenching gas located in the annular space 8 is compressed and flows when the heating effect of the arc 17 diminishes when the current zero point is approached, in the direction indicated by arrows via the annular channel 10 to the annular channel 12 and mixes there with the one from the annular space 6 flowing heated extinguishing gas.
  • the mixing of the fresh and the hot extinguishing gas is further supported by the fact that the annular spaces 6 and 8 are separated from one another by the annular wall 14 and that the wall 14 has an edge 19 projecting into the annular channel 12. The edge 19 creates a turbulent boundary layer between fresh and hot extinguishing gas and thereby promotes their mixing.
  • the extinguishing gas which is under high pressure but has cooled considerably, is passed into the extinguishing section located between the movable contact piece 1 and the ring electrode 3, where it blows the arc particularly effectively up to well beyond the current zero point and then via the nozzle-shaped opening of the erosion contact piece 1 enters an expansion room.
  • FIG. 2 shows a further exemplary embodiment of the switch according to the invention.
  • FIG. 1 a top view of a section through the contact arrangement of a switch is shown, in which the extinguishing gas is heated not by a rotating arc but by an arc drawn between the movable contact piece 1 and a full contact piece 2.
  • the insulating material body 5 is designed as a nozzle.
  • the piston 15 has a small cross section, so that when fresh extinguishing gas is compressed in the annular space 8, due to the strong pressure increase in the high-current phase when switching high currents, there is no drive braking.
  • the fresh and the heated extinguishing gas are mixed in the ring channel 12 and, due to the presence of two nozzles, namely the nozzle 5 and the nozzle-shaped hollow contact piece 1, the arc 17 is blown twice.
  • the embodiment of the high-voltage circuit breaker according to the invention shown in FIG. 3 essentially corresponds to the embodiment according to FIG. 2 1, however, like the switch according to FIG. 1, a piston 15 whose surface facing away from the annular space 8 for drive support again limits the annular space 7 connected to the heating volume 6.
  • a piston 15 whose surface facing away from the annular space 8 for drive support again limits the annular space 7 connected to the heating volume 6.
