Definitions

  • the invention is based on a hybrid power switch according to the preamble of claim 1.
  • the document EP 0 847 586 B1 discloses a hybrid power switch which can be used in an electrical high-voltage network.
  • This hybrid power switch has two series-connected extinguishing chambers, of which a first is filled with SF 6 gas as extinguishing and insulating medium, and a second is designed as a vacuum interrupter chamber. The second quenching chamber is surrounded outside by SF 6 gas.
  • the main contacts of the two extinguishing chambers are actuated simultaneously via a lever mechanism by a common drive.
  • Both extinguishing chambers have a power current path, in which the erosion-resistant main contacts are, and in parallel to a nominal current path, said nominal current path having only a single point of interruption. When switching off, the nominal current path is always interrupted first, whereupon the current to be switched commutes to the power current path. The power current path then carries the power on until its definitive shutdown.
  • the recurring voltage occurring across this hybrid power switch is distributed to these extinguishing chambers in accordance with the self-capacitances of the two extinguishing chambers.
  • the second, designed as a vacuum interrupter chamber, quenching chamber is acted upon by a large proportion of the recurring voltage, so that this second quenching chamber ignites in the rise of the recurrent voltage.
  • This ignition can occur several times when switched off. The ignition can cause unwanted oscillations in the high-voltage network associated with undesirable voltage increases.
  • the burn-off contacts of the vacuum interrupter chamber are additionally claimed by the ignition, so that their life is shortened.
  • a hybrid switch in which the voltage distribution over the two switching chambers by means of a capacitor which is parallel to the first, isolated with a gas and blown Switching chamber is connected, and by means of a non-linear resistor which is connected in parallel to the second, designed as a vacuum switching chamber switching chamber.
  • these two components ensure that the vacuum switching chamber is initially charged with the greater part of this recurrent voltage and holds it. Later, the first switching chamber then takes over the greater part of the applied voltage.
  • These two components for controlling the voltage distribution require a comparatively large volume in the interior of the switch housing of the hybrid switch, so that it requires a comparatively large and consequently also expensive switch housing.
  • the invention solves the problem of providing a hybrid circuit breaker, which is inexpensive to create and has a high availability.
  • the first steep rise of the recurring voltage is substantially maintained by the second quenching chamber formed as a vacuum switching chamber.
  • the reconsolidation of the extinguishing path of the first quenching chamber may therefore take place here relatively slowly, which means that the blowing of the first quenching chamber may be much less intense than conventional circuit breakers.
  • the pressurized gas required for the blowing of the arc so much less energy must be expended.
  • the advantages achieved by the invention can be seen in the fact that the hybrid circuit breaker can be equipped with the same power switching capacity with a much weaker and thus cheaper drive. Furthermore, the pressures occurring in this hybrid power switch in the first quenching chamber are much lower than in conventional circuit breakers, so that the insulating tubes and the other pressurized parts can be designed for lower loads, whereby a more economical design of the hybrid circuit breaker is possible. Furthermore, it has the advantageous effect that the flow velocity of the gas cooling the arc in the first quenching chamber can be in the subsonic range because of the considerably less intensive blowing required here, since thereby the amount of pressurized gas to be provided for the blowing can be kept comparatively small.
  • Another advantage is the fact that the Abbrand tokene the second quenching chamber, which is designed here as a vacuum interrupter chamber, because of the shorter duration of the current load when switching off and because of avoiding repeated skillsündens the rise of the recurring voltage have a longer life, which is advantageous improved operational availability of the hybrid circuit breaker result.
  • the hybrid circuit breaker is provided with at least two in series, operated by a common drive or separate drives, filled with different extinguishing media extinguishing chambers, the extinguishing and insulating medium of the first arcing chamber surrounding the second arcing chamber.
  • means which ensure a technically meaningful voltage distribution over the two extinguishing chambers during the turn-off.
  • means are provided, which at the switch-off a time advance of the movement of the first quenching chamber with respect to the Ensure movement of the second chamber.
  • the second quenching chamber When switching on, the second quenching chamber always closes in front of the first quenching chamber.
  • a quenching and insulating medium of the first quenching chamber a gas or a gas mixture is used.
  • As a second quenching chamber at least one vacuum switching chamber is provided. However, other switching principles can also be used for the second quenching chamber.
