Abstract (en)
[origin: WO2019007505A1] The invention is directed towards a direct current circuit breaking device (20 ) as well as to a method and computer program product for controlling the device. The circuit breaking device (20 ) comprises a branch comprising a number of series-connected current diverting modules, each current diverting module comprising a non-linear resistor (SA1, SA2, SA3, SA4) in parallel with a corresponding power switch (S1, S2, S3, S4), where the power switches together form a main breaker (MB) operable to be opened for diverting a current through the main breaker to the non-linear resistors (SA1, SA2, SA3, SA4). The power switches (S1, S2, S3, S4) are controlled, upon the circuit breaking device being set to interrupt a current through the power line, to be blocked according to a sequential blocking scheme.
