Abstract (en)
[origin: WO2021213769A1] A device (1) for limiting a short-circuit current in an on-load tap-changer (2), in particular in a load changeover switch (8) of the on-load tap-changer (2), comprising a first sensor (3) for measuring a current in a first current line (4) of the on-load tap-changer (2), an interruption element (5), a control apparatus (6) and a current-limiting element (7), wherein the interruption element (5) is arranged in the first current line (4) of the on-load tap-changer (2), the current-limiting element (7) is arranged in parallel with the interruption element (5), the first sensor (3) is designed to transmit a first measurement signal M, representing the measured current in the first current line (4) of the on-load tap-changer (2), to the control apparatus (6), the interruption element (5) is able to be actuated by the control apparatus (6) such that it is able to interrupt the channelling of current in the first current line (4) of the on-load tap-changer (2), such that the channelled current is switched to the current-limiting element (7).
