Definitions

  • the present invention relates to a switch, in particular a circuit breaker for a switchgear of the power supply and distribution.
  • Disconnectors are used for example as a three-position switch in a gas-insulated switchgear.
  • Such a three-position switch is a combined disconnect and earthing switch, which can take three switch positions “on”, “off” and “earth".
  • the three-position switch In the "On” switch position, the three-position switch connects a circuit breaker to a busbar.
  • the three-position switch In the "earth” position, the three-position switch connects the circuit-breaker to a ground potential and in the "off” position, the circuit-breaker is disconnected from the busbar as well as from the earth potential.

Further, a sleeve is provided whose opening dimension is larger than the cross-sectional dimension of the bolts of the first terminal and the second terminal and which is arranged so as to be axially slidable on the bolt of the first terminal and partly on the bolt of the second terminal.
  • At least one first contact element is disposed between the surface of the pin of the first terminal and the inner surface of the sleeve and at least one second contact element is arranged and configured such that it is located between the surface of the pin of the second terminal and the inner surface of the sleeve, when the sleeve is partially displaced on the bolt of the second connection.
