Zusammenfassung:An arrangement in an SF6 gas insulated electrical high voltage on-load switch, wherein the number of rotatable switch knives (13, 14; 15, 16; 17, 18) in the switch are arranged at evenly spaced intervals, projecting from a common revolving shaft (22), there being provided on each side of each of said knives a fan blade (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) which is freely rotatable, with the actual switch housing serving as the rotation chamber, and that said fan blades project from and are secured to said revolving shaft at an angle relative to the rotational axis (CL) of the revolving shaft. On rotation of the revolving shaft, turbulent gas flows are created around the switch contaces (20, 21) cooperating with the knife sets in a switch housing (19) in order to extinguish the electrice arcs around these switch contacts.
