摘要: The invention concerns a fast earthing switch (10) for a GIS comprising:
- a movable contact rod (12), having an end (14);
- a cylinder (20), fixed to said contact and forming a gas chamber (28) around at least part of said contact rod, said gas chamber comprising an outlet (22) around said contact rod so that gas can flow along said contact rod (12) and its end (14) when it moves from a closed to an open position;
- means (6, 8) for actuating said contact rod between a closed and an open position.
