Abstract: A switch comprises a first switching assembly (la) in a first metal enclosure (2a) and a second switching assembly (lb) in a second metal enclosure (2b). The two metal enclosures (2a, 2b) are electrically insulated from each other as well as from ground. This allows arranging a plurality of metal-enclosed switching assemblies in series while avoiding excessive electrical fields in any of them.

Abstract: A high voltage DC breaker apparatus configured to interrupt a fault current occurring in a high voltage DC conductor (1) comprises a mechanical interrupter (2), at least one semiconductor device (3) connected in series with the interrupter, an arrester (5) connected in parallel with the semiconductor device and an LC-circuit (6) connected in parallel with the series connection of the semiconductor device and the interrupter. A control unit (12) is configured to, upon detection of a fault current, control switching of the semiconductor device (3) at a frequency adapted to the values of an inductance (7) and a capacitance (8) of the LC-circuit for charging the capacitance by the fault current while making the current through the interrupter (2) oscillating with an increasing amplitude and the interrupter to open for having the mechanical contacts thereof separated when current zero-crossing is reached for obtaining interruption of the fault current through the interrupter.
