Abstract
The invention specifies a disconnector for decoupling a load from a supplying AC voltage network. The disconnector comprises at least one disconnector stage having a series circuit comprising at least two reverse-conducting gate turn-off thyristors which are connected cathode to cathode. The gate turn-off thyristors are preferably hard driven. This allows the use of a single circuit capacitor in parallel with the series-connected gate turn-off thyristors. This embodiment has the advantage that, during disconnection, the current commutates early from the gate turn-off thyristors, which means that the disconnection capacity can be increased.
