Definitions

  • the invention relates to a circuit breaker according to the Preamble of claim 1.
  • a circuit breaker according to the preamble of claim 1 is known from the two published documents DE 196 13 568 A1 and DE 196 13 569 A1, which can be used in an electrical high-voltage network, in particular also as a generator switch.
  • This circuit breaker has a cylindrical quenching chamber that is filled with SF 6 gas as the quenching and insulating medium.
  • This quenching chamber has a power current path, in which the erosion-resistant erosion contacts are located, which are connected by a bridging contact in the switched-on state, and also have a separate nominal current path equipped with the nominal current contacts.
  • the contacts in the two current paths are actuated by a drive via a lever linkage, the lever linkage being designed such that the rated current contacts can always be moved at a lower speed than the bridging contact.
  • the rated current contacts and the bypass contact run together, however, the rated current path is always interrupted first, after which the current to be switched off commutates to the power current path. The power current path then continues the current until it is definitely switched off. Circuit breakers of this type generally require a comparatively high drive energy. At the end of the switch-off stroke of the contacts, the kinetic energy of the moving parts, in particular that of the nominal current contacts, which have a comparatively large mass, must be damped in a complex manner.
  • circuit breaker is a lower Drive energy needed and therefore with a weaker and therefore cheaper drive can be equipped.
  • the circuit breaker is provided with at least one quenching chamber which is filled with an insulating medium, in particular SF 6 gas, is rotationally symmetrical and extends along a longitudinal axis.
  • the quenching chamber has a power current path with a central switching pin and a separate nominal current path provided with nominal current contacts.
  • the quenching chamber is operated with a drive linkage that moves the switch pin and the rated current contacts.
  • the drive linkage is designed so that at the beginning of the switch-off process the switching pin remains in a first dead center position until the rated current path is interrupted.
  • the switching pin can then be moved in the switch-off direction at a significantly higher speed than the rated current contacts.
  • the rated current contacts run into a second dead center position towards the end of their switch-off stroke.
  • the switching pin only reaches its switch-off position after the rated current contacts have ended their switch-off movement.
  • the rated current contacts remain in this second dead center position until the switch-on arc has pre-ignited. In this way, the nominal current contacts are advantageously protected from damage by an arc.
  • the circuit breaker has at least one first piston-cylinder arrangement, which is coupled to the rated current contacts and in which part of the insulating medium filling the arcing chamber is pressurized in a compression volume by a piston when it is switched off.
  • the pressurized insulating medium produced in this way often this is SF 6 gas, is used to support the blowing of the arc, which advantageously improves the breaking capacity of the circuit breaker, in particular even with small breaking currents.
  • this Circuit breakers at least part of the kinetic energy, which the nominal current contacts towards the end of their switch-off stroke have, with the help of the drive linkage for acceleration of the switch pin and for moving one with the Switching pin connected compression piston is usable. If this advantage can be exploited, the drive can be essential be dimensioned weaker, which is also priced has a favorable effect.
