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： An electric power distribution switchgear (11) is connected between an electric power grid and an electric power equipment (12). The switchgear comprises (i) a synchronized vacuum switching apparatus (16) configured to break the current to the electric power equipment (12) using a synchronized technique to avoid re-ignition during the breaking and thus any transients caused by such re-ignition; and (ii) a surge arrester arrangement (17) connected to the electric power equipment(12), the surge arrester arrangement being designed and configured to only handle transients caused by the current chopping at the breaking. Hereby, the surge arrester arrangement (17) can be arranged remote from the electric power equipment(12), such as e.g. in the same casing(21) as the synchronized vacuum switching apparatus (16).

摘要： The present disclosure relates to a start-up method for reducing inrush current to a transformer (3) when closing a switching device (2). The method comprises monitoring a voltage (U) in one of the phases. The method also comprises, for each of a sequence of iterations: at a same opening angle relative to a reference angle of the monitored voltage, opening the switching device; at a closing angle relative to the reference angle, which is shifted in relation to the closing angle of all other iterations in the sequence, closing the switching device; and obtaining a peak value of the overall inrush current resulting from the closing. The method also comprises selecting for future use with said same opening angle, the closing angle of one of the iterations in which the overall inrush current is relatively low when compared with the other iterations of the sequence.
