摘要: A device (2) for control of a power flow in a three-phase ac transmission line (L2, La, Lb, Lc) has, for each of its phases (a, b, c), a transformer (12a, 12b, 12c) with a primary winding (121c) and a secondary winding (122c). The secondary winding is serially connected into the respective phase of the transmission line. A voltage dependent on a controllable part of the voltage between the other two phases of the transmission line is applied to the primary winding of the transformer. The device comprises, for each of the phases of the transmission line, a series circuit with a first (T1a, T1b, T1c) and a second (T2a, T2b, T2c) terminal and a connection point (Ja, Jb, Jc). The series circuit comprises a first reactive impedance element (21a, 21b, 21c) with a fixed reactance connected between the first terminal and the connection point, and a second reactive impedance element (22a, 22b, 22c, 23a, 23b, 23c) with a variable reactance connected between the connection point and the second terminal. One of said terminals is coupled to the respective phase of the transmission line and the other terminal is coupled to a terminal at each of the other two series circuits so that, for all the phases, either the first or the second terminal is coupled to the transmission line. The mentioned primary winding is coupled between the connection points at the other two series circuits.

摘要: A device for quick closing of an electric high-voltage circuit. A main spark gap is provided with a first and a second main electrode, and a triggering device. The triggering device includes an auxiliary electrode gap provided with a first and a second auxiliary electrode and is adapted, where necessary, to generate an arc in the auxiliary spark gap for igniting an arc in the main spark gap. Each auxiliary electrode is provided with a guide rail designed such that the arc, via the guide rails and under the influence of the generated inherent magnetic field, moves into the main spark gap. The two guide rails each have a length that is larger than the width of the auxiliary spark gap. The auxiliary electrodes are adapted so as to be protected from the effect of plasma formed in the main spark gap. A hermetic enclosure encloses the main spark gap and the auxiliary spark gap.
