Abstract:
A circuit breaking arrangement is disclosed, which is adapted to be coupled to a transmission line arranged to carry direct current for controllably effecting discontinuation of flow of direct current in the transmission line. The circuit breaking arrangement includes a current interrupter unit, which is adapted to, when actuated, interrupt current in the transmission line, and at least one resonance circuit. The resonance circuit is connected in parallel with the current interrupter unit and includes at least one capacitor, at least one inductor and at least one switch element. The resonance circuit is adapted to, upon actuation of the current interrupter unit, generate a resonance current superposing current of any arc generated in the current interrupter unit after actuation thereof, upon closing of the switch element by means of successive discharging and charging of the at least one capacitor. An auxiliary power supply unit is coupled to the resonance circuit and adapted to selectively and controllably convey power to the at least one capacitor, thereby charging it. On a condition that voltage of the transmission line and/or voltage of the at least one capacitor does not comply with a selected voltage criterion, the auxiliary power supply unit is caused to convey power to the at least one capacitor. The circuit breaking arrangement may be arranged so as to allow for conveyance of power transmitted in the transmission line to the at least one capacitor, thereby charging it.
