Abstract (en)
[origin: CN117334516A] The invention relates to a low, medium or high voltage switching system comprising: a vacuum interrupter; and a magnetic system; wherein the vacuum interrupter comprises a fixed contact and a movable contact; wherein in the closed configuration of the switching system, the vacuum interrupter is configured to maintain the movable contact in contact with the fixed contact; wherein in an open transition of the switching system, the vacuum interrupter is configured to move the movable contact away from the fixed contact; and wherein the magnetic system is configured to generate a magnetic field having magnetic flux lines that are directed through a gap between the movable contact and the fixed contact during the open transition; and wherein the axis of the vacuum interrupter is guided through the center of the fixed contact and through the center of the movable contact, and wherein the magnetic flux line is guided perpendicular to the axis of the vacuum interrupter.
