Abstract
A blasting piston ('puffer') circuit breaker having two stationary nozzle-shaped contacts which are bridged in the 'on' position by a hollow, cylindrical, movable contact and an annular body of insulating material for reducing the cross-section of the oncoming flow between the stationary contacts during the course of the switching-off motion. The annular body has an axial dimension smaller than the length of the gap between the stationary contacts and is placed approximately in the middle between the bottom of the cylinder and the free end of the movable contact.
