Definitions

  • Switches in which the aforementioned method is performed, are generally operated in the voltage range of about 70 kV and dominate turn-off currents of several 10 kA. They are filled with an arc-containing insulating gas, such as based on sulfur hexafluoride and / or nitrogen and / or carbon dioxide, of generally up to a few bar pressure. If these circuit breakers interrupt a large, typically 50 kA, amounting, short-circuit current, then a considerable amount of compressed gases is released by the forming switching arc, which are stored in a heating volume as compressed extinguishing gas and as the current to be cut approaches a zero crossing of a blower serve the switching arc.
  • an arc-containing insulating gas such as based on sulfur hexafluoride and / or nitrogen and / or carbon dioxide
  • the insulating gas is compressed in a compression space having two communicating with each other Operakompressionsschreib.
  • the two partial compression spaces are spaced from one another along an axis of symmetry of a circuit breaker and are each delimited by one of two piston-cylinder arrangements.
  • When switching off a drive of the switch reduces the volumes of the two compression chambers at the same time and is compressed in the two partial compression spaces and provided in a heating volume insulating gas.
  • the compressed insulating gas flows when approaching the current to be disconnected to a zero crossing as quenching gas in an arc extinguishing zone of the switch in which a switching arc between two separate arcing contacts burns.
