Claim:
1. A switchgear cabinet comprising: a cabinet frame; first and second current converter devices arranged in the switchgear cabinet and supported by said cabinet frame; and an electrical connection clamping device; wherein said first current converter device has first power semiconductor components and, for electrical connection of said first current converter device, a first DC voltage positive potential connection element and a first DC voltage negative potential connection element; wherein an electrically non-conductive first insulation element is arranged between said first DC voltage positive potential connection element and said first DC voltage negative potential connection element; wherein said second current converter device has second power semiconductor components and, for electrical connection of said second current converter device, a second DC voltage positive potential connection element and a second DC voltage negative potential connection element; wherein an electrically non-conductive second insulation element is arranged between said second DC voltage positive potential connection element and said second DC voltage negative potential connection element; wherein said electrical connection clamping device has an electrically conductive first clamping element and an electrically conductive second clamping element, which is arranged such that said electrically conductive second clamping element is electrically insulated from said electrically conductive first clamping element, and a pressure-generating device for generating a pressure which pushes said electrically conductive second clamping element toward said electrically conductive first clamping element; wherein said pressure-generating device pushes said second electrically conductive clamping element against said first and second DC voltage positive potential connection elements and, by means of said first DC voltage positive potential connection element and said first insulation element, pushes said first DC voltage negative potential connection element against said electrically conductive first clamping element and, by means of said second DC voltage positive potential connection element and said second insulation element, pushes said second DC voltage negative potential connection element against said electrically conductive first clamping element; and wherein said first electrically conductive clamping element is mechanically connected to said cabinet frame by an electrically non-conductive insulation body such that said electrically conductive first clamping element is electrically insulated from said cabinet frame.
