Electromagnetic actuator, electrical switching unit comprising an electromagnetic actuator of this kind

An electromagnetic actuator includes a fixed body, a moving part forming a magnetic core of the actuator and being movable in translation with respect to the fixed body between a retracted position and a deployed position, a magnetic piece forming a permanent magnet adjusted to generate a first magnetic force holding the moving part in the retracted position, and a coil adjusted to engender a second magnetic force opposed to the first magnetic force when the coil is supplied with an electrical excitation current. The moving part includes one or more notches formed in a body of the moving part.

A method for diagnosing the wear status of an electrical switching unit including a phase for monitoring the electrical unit. The monitoring phase uses: learning data previously loaded and representative of the type of electrical unit, and initialization data corresponding to the unit to be monitored and stored in memory during an initialization phase. The monitoring phase includes the measurement and the acquisition of a measurement curve upon the opening of the electrical unit, the determination of values of local descriptors with little sensitivity to the temperature from the measurement curve as a function of values of the measurement curve, of initialization data, and of learning data, the determination of a global status class as a function of the positioning values. The device and the electrical unit implement the method.

A reactive power compensator for a three-phase network having first, second and third phases includes an assembly of capacitors and electromechanical contactors electrically connected to the capacitors. Each contactor includes at least one upstream and one downstream power terminal. An electric current circulates between the upstream and downstream power terminals when the contactors are closed. A first contactor is connected to the first phase and a second contactor is connected to the third phase. The voltage between the upstream and downstream power terminals of at least one electromechanical contactor is measured so that the electromechanical contactors can be controlled according to a control algorithm. The control algorithm includes the closure of a contactor for a substantially zero voltage between the upstream and downstream power terminals thereof, and the opening a contactor for a substantially minimum power value of the capacitors to which the contactor is connected.
