摘要 |
A rotary switch with a sealed enclosure in which a rotating knife-blade is housed cooperating with two stationary contacts supported by the internal periphery of the enclosure. A permanent magnet is incorporated in the stationary contacts to magnetically blow the arc roots on a curved migration track towards hidden locations which are not facing the knife-blade. The invention is applicable to a gas-insulated medium voltage switch. |
