摘要:
An electrical switching device (1-1) comprising: a main contact arrangement (3) comprising a fixed contact (3b) and a movable contact (3a), a plurality of splitter plates (5, 5b, 5c), each having a loop structure (5a), the splitter plates (5, 5b, 5c) being coaxially stacked with respect to their loop structure (5a) to form a stack of splitter plates (7), wherein one of the splitter plates (5b) of the stack of splitter plates (7) is a first outermost splitter plate (5b) and another one of the splitter plates (5c) of the stack of splitter plates (7) is a second outermost splitter plate (5c), a first arc runner (9a) electrically connected to the second outermost splitter plate (5c) and a second arc runner (9b) electrically connected to the first outermost splitter plate (5b), the first arc runner (9a) and the second arc runner (9b) being configured to direct a main arc (11) from the main contact arrangement (3) to the stack of splitter plates (7) to thereby split the main arc (11) into a plurality of secondary arcs (19) between the splitter plates (5, 5b, 5c), and a first drive coil (13) electrically connected to the second arc runner (9b) and to the movable contact (3a) or to the first arc runner (9a) and to the fixed contact (3b), wherein the first drive coil (13) has a first force increasing coil portion (13) extending in parallel with the first arc runner (9a) in a direction towards the splitter plates (7) such that the first force increasing coil portion (13a) is able to carry current (17) in the same direction as and in parallel with a main current flow in the first arc runner (9a) to increase the magnetic field to thereby increase the Lorenz force applied to the main arc (11) between the first arc runner (9a) and the second arc runner (9b), when energised, is configured to create a blowing magnetic field in the stack of splitter plates (7), causing the secondary arcs (19) to move circumferentially along the loops structures (5a) of the splitter plates (5, 5b, 5c).
