Abstract (en)

[origin: EP0731482A2] The power switch includes a quenching chamber (1) filled with an insulating medium which includes at least one power current track. A moving contact piece (2) is arranged in the power current track. A fixed contact piece (3) is also provided. A blow-out coil (22) is at least partially driven by current. A blow-out volume stores the raised pressure of the insulating medium caused by the switch-off process. The blow-out coil can be completely or partially short-circuited. Components are provided to execute the short-circuiting.
