Abstract
The invention relates to a power switch (100) that comprises a contact element (105, 107) mobile in an axial direction and an extinction gas flow that moves in said axial direction when the switch is actuated. Said extinction gas flow is coaxially surrounded by a flow guide device (1, 1a,b,c) one surface area of which is provided with at least one discharge opening (10a,b,c,d,e,f,g,h,i,j,k,l; 12a,b,c,d,e,f) for deflecting at least a part of the extinction gas flow towards a discharge direction, said discharge direction being oriented tangential and substantially at an angle to the axial direction.
Claims8
A power breaker, comprising:
- a contact piece which is configured to move in an axial direction and has a flow of quenching gas which, when the breaker is operating, moves in the axial direction and which is coaxially surrounded by a flow-deflecting device, which has a first and a second outflow opening in an outer surface for deflecting at least some of the flow of quenching gas in a first and in a second outflow direction, wherein
- some of the flow of quenching gas emerging from the first outflow opening is deflected towards some of the flow of quenching gas emerging from the second outflow opening, and the flows of quenching gas intersect one another.
