below the module 60 by means of the mains connections 42 b aligned substantially perpendicular to the power modules as can be seen a substantial proportion of the connection paths between the individual components of the power module 6 is bridged by the arrangement of the individual components along the power flow fig6 schematically shows the design of an exemplary embodiment of a switch cabinet arrangement 64 in the form of a circuit diagram this comprises the power switch cabinet 1 from fig1 and two other switch cabinets 1 u2032 1 u2033 preferably of the same design the power switch cabinets 1 1 u2032 1 u2033 are connected in parallel it is also conceivable for the power switch cabinets 1 1 u2032 1 u2033 to be provided with a different layout in a switch cabinet arrangement 64 in order if necessary to achieve better power adaptation it is also conceivable to provide just two or more than three power switch cabinets here the arrangement of the components in the individual power switch cabinets as already shown in fig1 is in each case in the direction of the power flow 5 so that in this case three parallel power flows result in the three power switch cabinets 1 1 u2032 1 u2033 a rotor 66 drives a permanent magnet excited synchronous generator 68 this has an electrically conductive connection via a generator switch 70 which can optionally be provided in a generator connection cabinet not shown with the power switch cabinets 1 1 u2032.
