Abstract

Et energiomformingssystem er fremvist, hvilket omfatter en elektrisk maskin (32) eller en gruppe av elektriske maskiner (32), hvor hver separate viklingsgruppe (50) innenfor en elektrisk maskin (32) eller individuelle elektriske maskin (32) i gruppen av elektriske maskiner er galvanisk koblet til en assosiert AC/DC-omformerenhet (likeretter) (33). Energilagringskretser (DC-linker) (34) for omformerne (33) er koblet til hverandre i serie og skaper en felles DC-høyspenning (45). Videre er hver separate viklingsgruppe (50) innenfor en elektrisk maskin (32) eller individuelle elektriske maskin (32) i gruppen av elektriske maskiner (32) omgitt av en elektrisk skjerm (60, 60A-E) av ledende eller halvledende materiale for omfordeling av elektriske potensialer innenfor systemet. Potensialomfordelingen tillater at spalteisolasjon for elektriske maskiner (32) kan utformes for betydelig lavere spenning enn den felles DC-høyspenningen (45). Dette betyr tynnere spalteisolasjon, bedre feildeteksjon og maskinstørrelsen blir betydelig mindre enn for tilsvarende maskiner med høyspenningsisolasjon.An energy conversion system is provided, comprising an electric machine (32) or a group of electric machines (32), wherein each separate winding group (50) within an electric machine (32) or individual electric machine (32) in the group of electric machines is galvanically connected to an associated AC / DC converter unit (rectifier) (33). The energy storage circuits (DC links) (34) of the inverters (33) are connected in series and create a common DC high voltage (45). Further, each separate winding group (50) within an electrical machine (32) or individual electric machine (32) in the group of electric machines (32) is surrounded by an electrical shield (60, 60A-E) of conductive or semiconducting material for redistribution of electrical potentials within the system. The potential redistribution allows gap insulation for electric machines (32) to be designed for significantly lower voltages than the common DC high voltage (45). This means thinner gap insulation, better fault detection and the machine size becomes considerably smaller than for similar machines with high voltage insulation.
