Abstract: 599794 Disclosed is a device (13) for breaking a direct electrical current flowing through a power transmission or distribution line (14). The device (13) is comprised of a parallel connection of a main breaker (8) and a non-linear resistor (11). The main breaker (8) is comprised of at least one power semiconductor switch of a first current direction (4). The device (13) is further comprised of a series connection of a high speed switch (10) and an auxiliary breaker (9). The high speed switch (10) is comprised of at least one mechanical switch. The auxiliary breaker (9) has a smaller on resistance than the main breaker (8) and is comprised of at least one power semiconductor switch of the first current direction (4). The series connection of the high speed switch (10) and auxiliary breaker (9) is connected in parallel to the parallel connection of the main breaker (8) and the non-linear resistor (11). The device (13) is adapted to open the auxiliary breaker (9) upon receipt of an auxiliary breaker signal prior to a decision to open the main breaker (8) having been taken.

Abstract: Una instalacion para transmitir energ¡a electrica por medio de HVDC comprende dos estaciones convertidoras (101, 102) interconectadas mediante una red de corriente continua bipolar (103), estando cada una de ellas conectada a una red de voltaje alterno (104, 105). Cada estacion convertidora tiene un Convertidor de Fuente de Voltaje con celdas de conmutacion, cada uno de los cuales incluye por lo menos un condensador de almacenamiento de energ¡a. Los Convertidores de Fuentes de voltaje est n configurados para utilizar un voltaje continuo que para uno primero de los polos tiene una magnitud con respecto a tierra que es superior a la magnitud para uno segundo de los polos.

Abstract: A device (13) to break an electrical current flowing through a power transmission or distribution line (14) comprises a parallel connection of a main breaker (8) and a non-linear resistor (11), where the main breaker (8) comprises at least one power semiconductor switch of a first current direction. The device (13) further comprises a series connection of a high speed switch (10) comprising at least one mechanical switch and of an auxiliary breaker (9), the auxiliary breaker having a smaller on-resistance than the main breaker (8) and comprising at least one power semiconductor switch of the first current direction. The series connection is connected in parallel to the parallel connection. In a method to use the device (13) first the auxiliary breaker (9) is opened, thereby commutating the current to the main breaker (8), afterwards the high speed switch (10) is opened and afterwards the main breaker (8) is opened thereby commutating the current to the non-linear resistor (11). The device (13) can further be used in a current limiting arrangement.

Abstract: A DC cable for high voltages having at least an inner conductor surrounded by an insulating layer configured to take the voltage to be taken between the conductor and the surroundings of the cable. The insulating layer is formed by a plurality of superimposed film-like layers of insulating material each having isolated areas of metal on top thereof. The metal areas of consecutive such film-like layers are at least partially overlapping each other as seen in the radial direction of the cable so as to create a large number of small capacitors in said insulating layer of the cable.
