Abstract (en)
[origin: WO2010102989A1] The invention relates to a magnetic actuation device for a high voltage apparatus for a vacuum bulb, that includes at least one permanent magnet and at least one coil (3) mounted in series with a transistor switch (4), wherein an electromechanical switch (EM1) is mounted in series with the transistor switch (4) and the coil (3), the first electromechanical switch (EM1) and the transistor switch (4) being by default in an open state so that the electromechanical switch is closed a moment before the closing moment of the transistor switch, and is returned to an open state as soon as the transistor switch is returned in the open state. The invention can be used for turning on and off medium and/or high voltage apparatuses.
