Title: HIGH-VOLTAGE DC CUT-OFF DEVICE
Abstract:
The invention relates to a current cut-off device (1) for high-voltage DC current, comprising: • in series, a cut-off apparatus (121) and a current limiter (111); • an accumulation line (130) in parallel with the current limiter (111), • an oscillating circuit (142), in parallel with the cut-off apparatus (121), comprising an oscillation control switch (122) and having an inductance (133) characterised in that the accumulation line (130) comprises at least two accumulation capacitors (131, 132), and in that the oscillation line extends from a branch connection point (135) of the accumulation line located between the two accumulation capacitors (131, 132), determining a secondary segment (137) of the accumulation line (130) connected to the main conduction line (141) between the current limiter (111) and the main cut-off apparatus (141) so as to form part of the oscillating circuit.
