摘要： Embodiments provide a switch, including a control system, first and second manipulating mechanisms. The control system emits an operating instruction to the second manipulating mechanism when the wire works normally, the operating instruction instructing the second manipulating mechanism to perform an opening action or a closing action; the control system emits a first and second action instructions to the first and second manipulating mechanisms, respectively, when the wire fails, the first action instruction instructing the first manipulating mechanism to perform a first action, and the second action instruction instructing the second manipulating mechanism to perform a second action, the cooperative action between the first manipulating mechanism and the second manipulating mechanism implements redundancy of the switch operating; and the time taken by the first manipulating mechanism to implement the first action is different from the time taken by the second manipulating mechanism to implement the second action.

摘要： A system for limiting a peak current of short-circuit current comprises a first high-frequency branch configured to provide a first high-frequency current to a first switch (1SKa) of a first phase branch of a three-phase AC when the first phase branch occurs a short-circuit; a second high-frequency branch configured to provide a second high-frequency current to a second switch (1SKc) of a second phase branch of the three-phase AC when the second phase branch occurs a short-circuit; and a third phase branch of the three-phase AC connected in parallel with the first phase branch and the second phase branch and configured to always supply power.

摘要： The present invention discloses a system for limiting a peak current of short-circuit current, which comprises a first a first high-frequency branch configured to provide a first high-frequency current to a first switch (1SKa) of a first phase branch of a three-phase AC when the first phase branch occurs a short-circuit, wherein the first high-frequency current is configured to cause a zero-crossing point of a short-circuit current to appear before a zero-crossing point of the three-phase AC; a second high-frequency branch configured to provide a second high-frequency current to a second switch (1SKc) of a second phase branch of the three-phase AC when the second phase branch occurs a short-circuit, wherein the second high-frequency current is configured to cause a zero-crossing point of a short-circuit current to appear before a zero-crossing point of the three-phase AC, a third phase branch of the three-phase AC connected in parallel with the first phase branch and the second phase branch and configured to always supply power. The present invention superimposes the high-frequency current on the original short-circuit current of the switch, thereby the total time from the arc generation to extinction at the zero-crossing point and then to the judgement by the control system is shorter than the time that the short-circuit current peak appears. Therefore, it can effectively lower the damage of the short-circuit current peak to the dynamic stability of the switch and lower the impact on system equipment.
