摘要： A high power d.c. breaker for connection into a d.c. carrying high-voltage line (L), has two normally closed and electrically series-connected mechanical breaks (BSI, BSII) adapted to be traversed by the line current (I) and to be opened for breaking the current. A capacitor (CB) is connected in parallel with the series connection of the breaks. A semiconductor member (HO) is connected in parallel with one of the breaks (BSI). Upon opening the breaks, a control member (SO) controls the semiconductor member such that a zero crossing of the current through the second break (BSII) is obtained, whereby the line current (I) is commutated over to the capacitor. (FIG. 1)

摘要： A method and a device in an electric power network (1), comprising an active filter (4) controllable via a control input (41), for reducing disturbances generated by a disturbance source (6) located in and/or connected to the power network. A control member (8) is adapted, based on at least one first state variable (Y1i) sensed in the power network (1) and a model of the power network (1), to calculate the disturbances (X2) which occur in a second section (B--B) in the power network (1) without action from the active filter (4), to calculate a control signal (C1) such that, supplied to the control input (41), it would generate in the second section (B--B) the calculated disturbances (X2) with reversed polarity, and to generate the control signal (C1) and supply this to the control input (41). By sensing, in addition, at least one second state variable (Y2i) in the second section (B--B), the control signal (C1) can also be generated in dependence on the control deviation (DU) of the second state variable (Y2i) from a desired value (Y2R).

摘要： A thyristor overvoltage protection circuit wherein an avalanche diode conducts to divert overvoltage energy from a thyristor to avoid self-ignition of the thyristor when the overvoltage reaches a particular level. A simulator circuit monitors the thermal loading on the conducting diode and activates an ignition pulse device if the thermal loading exceeds the safe operational range of the diode. The activated ignition pulse device ignites the thyristor so that the thyristor may divert the overvoltage energy and thereby discharge the diode.
