Title: COOLING SYSTEM FOR GAS-COOLED SWITCHING LINES
Abstract:
The invention relates to a switching line cooling device (1) for gas-cooling of the electrical connection of a stator winding of a turbo generator, having a switching line (2) with a gas-cooled hollow conductor path (12) which, along a first part length (12.1), has a first cooling duct (14.1) that extends from a high-pressure chamber (80) to a low-pressure chamber (90) of the turbo generator, wherein the cooling device (1) has a second cooling duct (14.2) that extends, along a second part length (12.2) of the hollow conductor path, in the high-pressure chamber to a gas interface (20) of the second part length and thence in a fluid line (22) of the second cooling duct to the low-pressure chamber.
