Abstract
A circuit interrupter comprises a pair of contacts in a container filled with a gas for extinction; an insulation nozzle around the contacts to form an arc chamber; a gas chamber which is connected to the arc chamber under departing the contacts. The gas pressure in the arc chamber and the gas chamber is increased by the energy of the arc generated at the departing the contacts. When the arc current is large, the flow-out of the gas from the arc chamber and the gas chamber is decreased by the arc whereas the high pressure gas in the arc chamber and the gas chamber is discharged through the insulation nozzle into the container at the time decreasing the arc current near zero whereby the arc is interrupted by the gas flow discharged.
