Embodiment Construction

[0026] exist figure 1 , a water-cooled stator bar 10 of a turbogenerator is shown, with steel cooling channels 1 and copper component conductors 2 at the axial ends of the stator bar 10, where the stator bar 10 is electrically connected by means of copper conductor modules 3. Connection, and by means of the tank bottom plate 4 can be connected to the cooling water circuit of the turbine generator.

[0027] The individual steel cooling channels 1 are fastened to the tank floor 4 by circumferential, waterproof welds 5 . On the side of the water tank bottom plate 4 facing away from the stator rod 10, a water tank 11 is formed for connecting the stator rod 10 to the cooling water circuit.

[0028] The water tank 11 is composed of a water tank bottom plate 4 and a water tank cover 12, and the water tank cover 12 is fixed and screwed to the water tank bottom plate 4 by four bottom plate connecting elements 8 configured as screws. The pressure between the tank cover 12 and the tank...

Abstract

The invention relates to a water chamber cover (12) for connecting a water hose (13) to a water chamber bottom plate (4) of a directly water-cooled stator bar (10), comprising a peripheral groove (9),which is open on a side facing away from the water chamber (11) and which is designed to hold the water hose. The invention further relates to a method for assembling a cooling water circuit for a directly water-cooled stator bar.

Description

technical field [0001] The invention relates to a radiator cover for connecting water pipes to the radiator base plate of a direct water-cooled stator bar in an electric motor, and to a cooling circuit connection fitting with such a radiator cover and for mounting a cooling circuit for direct water-cooled stator bars Methods. Background technique [0002] In known turbogenerators and other electrical machines, the turbogenerator stator windings are usually cooled in a conventional manner by direct water cooling, in which cooling water circulates in the stator bars through cooling channels in which deionized water flows. Known water cooling systems include eg a water collector ring at the generator housing, water tanks at the ends of the rods and water cooling channels in the rods. However, instead of running over the water or cooling channels, the current path in the stator windings runs along the bars over the solid copper. [0003] In known direct water cooling of the st...
