Pressing module for impregnated conductor bars of large electrical machines and pressing apparatus equipped therewith

摘要

The module has a pressing unit comprising two outer bars with a closing unit (6) that applies pressing force on an impregnated conductor rod. The closing unit and/or a closing unit of a transverse beam have a housing (20) enclosing a hollow chamber (22) with an inner contour (23). A pressing piston (21) is slidingly supported at the inner contour, and has a threaded hole (25) communicating with an axially fixed threaded bolt (27), where rotational movement of the bolt causes axial movement of the piston. The piston moves through a through-flow opening (28) from the housing. An independent claim is also included for a pressing device comprising a pressing module.
