摘要： A method of operating a switching device in a system. The method includes monitoring a voltage; operating the system at each of a plurality of system configurations; and, for each of the system configurations and a predetermined same opening angle relative to a reference angle of the monitored voltage, determining a suitable closing angle relative to the reference angle and storing information about the determined suitable closing angle in association with the system configuration in a database. The method then includes, determining a system configuration in the system; at the predetermined same opening angle, opening the switching device; from the database, obtaining a closing angle of the determined suitable closing angles, wherein the system configuration with which the obtained closing angle is associated in the database corresponds to the determined system configuration; and at the obtained closing angle, closing the switching device.

摘要： The present invention relates to a method for controlling a motor-driven vacuum circuit breaker. The method comprises initiate opening (S100) the circuit breaker, wherein the circuit breaker moves with an average opening speed of a contact pair of the circuit breaker, from a closed position to an open position of the circuit breaker, and decelerating (S110) the opening speed of the contact pair to below the average opening speed before the open position is reached to avoid overshoot, and initiate closing (S120) the circuit breaker, wherein the circuit breaker moves with an average closing speed of the contact pair, from the open position to the closed position, and decelerating (S130) the closing speed of the contact pair to below the average closing speed before contact touch at the closed position, wherein the circuit breaker moves with the decelerated speed at contact touch. A motor-driven vacuum circuit breaker, a computer program and a computer program product are also presented.

摘要： A switching device for low or medium voltage electric power distribution networks, the switching device comprising: at least an electric pole comprising a movable contact and a fixed contact, which are coupleable/decoupleable one to another; a circuit assembly, which comprises a chain of semiconductor devices adapted to switch in an ON state or in an OFF state depending on the voltage applied thereto, the semiconductor devices being electrically connected in series one to another in such a way that a current can flow according to a predefined conduction direction (CD) when the semiconductor devices are in an ON state. The circuit assembly comprises an input terminal, an output terminal and at least an intermediate terminal electrically connected with at least an intermediate electric node positioned between two subsequent semiconductor devices. The input terminal is electrically connected with the fixed contact: the input terminal, the output terminal and the at least an intermediate terminal are electrically coupleable/decoupleable with/from the movable contact when the movable contact reaches different positions during a movement towards/away from the fixed contact in such a way that different groups of semiconductor devices switch in an ON state or in an OFF state at different instants during the movement of the movable contact, depending on the position reached by the movable contact.
