Abstract

The invention relates to electrical engineering, in particular to magnetic actuators of vacuum high-voltage switches. The proposed magnetic actuator for a vacuum switch includes laminated magnetic core, actuating and shutdown coils, an armature and permanent magnets. The magnetic actuator is provided with two magnetic chucks which retain the armature in two extreme positions due to action of permanent magnets. The armature has two end clearances: one- near the left butt end, and the other - near right butt end. New in the inventive magnetic actuator is: presence in the said actuator a number of galvanically not connected shutdown coils with nominal power no more than 0,33 kW each, as well as, in addition, two lateral clearances near one butt end in aria of the shutdown coils. Magnetic conductivity of lateral clearances is several times greater than magnetic conductivity of the end clearance. This made it possible to decrease several times power consumption of magnetic actuator shutdown coils and to increase switch reliability, as well as not to use pre-charged condensers when magnetic actuator is switched off.
