Abstract

An electric arc interruption arrangement comprising: a movable, electrically insulating barrier (102) arranged to move from a first position to a second position, wherein in the second position, the movable, electrically insulating barrier is positioned within an arc zone (118) between a first electrode (106) and a second electrode (108), an electrically conducting coil (104) comprising at least one turn about an axis (122), the coil having a first end (112) and a second end (114), wherein the first end is positioned closer to the first and second electrodes compared to the second end, and second end (114) is electrically connected to one of the first electrode (106) and the second electrode (108) without passing through the coil, wherein the movement of the electrically insulating barrier (102) from the first position to the second position is parallel to the axis of the coil from the first end to the second end, wherein the electrically insulating barrier is arranged to push, by its movement, an arc (116) formed in the arc zone between the first electrode and the second electrode into the coil at its first end, whereby the arc induces an electric current through the electrically conducting coil, thereby generating a magnetic field that acts on the arc.
