  • Gas-blast breaker
    Patent number: 4839482
    Abstract: The gas-blast breaker exhibits two contact members (1, 2) which are located in a housing filled with insulating gas and can be brought into and out of engagement with one another along an axis (5), and an insulating material nozzle (4) through the nozzle constriction (6) of which an arc burns during a switching process. The nozzle constriction (6) is formed by several segments (7) which follow one another in the circumferential direction, can be moved in the radial direction and can be loaded with a centripetally acting force.In this gas-blast breaker, the cross-section of the nozzle constriction (6) which is effective during a switching process is intended to be largely independent of the number of switching processes performed and causing nozzle erosion.
