Abstract: A method for estimating the state of an electrical switching apparatus, the switching apparatus including separable electrical contacts configured to be coupled to an electrical conductor, and an electromagnetic actuator, controlled by a control circuit and including a movable core, coupled to the separable contacts, and a coil, which is passed through by a coil current. The method: includes measuring, by means of sensors associated with the coil, values of the coil current in a time interval, while the electromagnetic actuator is kept in a stable and in particular closed position, and computing, by means of an electronic control device of the switching apparatus, one or more values of a magnetic flux of the coil from the measured coil-current values, and using coil-voltage and coil-resistance values known beforehand.

Abstract: Embodiments of the present disclosure provide a control method and a control device for an electric switch, and an electric switch. The control method includes: obtaining a voltage signal representing a control voltage, the control voltage input to the electric switch and applied to an electromagnetic assembly of the electric switch via a regulation device of the electric switch; determining, based on the voltage signal obtained, a target control parameter for the electromagnetic assembly, the target control parameter comprising at least one of a target voltage and a target current; and generating, based on the target control parameter determined, a control signal for the regulation device, to cause the electromagnetic assembly to drive a movable contact of the electric switch to contact a static contact of the electric switch. The solution of the present disclosure can effectively reduce wear of contact points of contacts, to thus prolong the service life of the electric switch.

Abstract: Embodiments of the present disclosure relate to a control circuit for a contactor and a control method thereof. The control circuit comprises: a pulse converter configured to convert a turn-on control signal into a continuous pulse signal; a first controller configured to generate a first breaking control signal at a first time in response to detection of the disappearance of the continuous pulse signal received from the pulse converter; a second controller configured to generate a second breaking control signal at a second time in response to detection of the disappearance of the continuous pulse signal received from the pulse converter, wherein the first time is earlier than the second time; and a coil driver configured to turn off a current of the excitation coil according to the received first breaking control signal, and if the current is not turned off according to the first breaking control signal, to further turn off the current of the excitation coil according to the second breaking control signal, thereby realizing the breaking of the main contact.
