End copper shielded double-water internal cooling turbine generator

The utility model relates to a copper shield turbo-generator with inner water cooled stator and rotor for the end portion, comprising a stator core, a stator winding bar, a clamping ring, a clamping ring cooling water pipe and a rotor, and is characterized in that the clamping ring cooling water pipe is demolished, the outsides of the two end clamping rings of the stator core are provided with the copper shield, and a bracket is provided in the outside of the copper shield. The utility model has the advantages that the temperature of the stator end constructional element is reduced, the nominal output of the airturbine generator is enhanced, the wasting is reduced, and the radial runnability and efficiency are enhanced.
