SUBMERSIBLE WATER-FILLED SYNCHRONOUS GENERATOR OF VERTICAL DESIGN Russian patent published in 2013 - IPC H02K21/24 H02K5/12 H02K5/167 F04D13/08 

FIELD: electricity.

SUBSTANCE: proposed submersible water-filled synchronous generator of vertical design comprises a basic shield, where a circular flat magnetic conductor is fixed, wound from electric steel, with a winding, a rotor disc with permanent magnets, a bearing shield arranged as cantilevered relative to the basic shield and comprising bearings of the rotor shaft. At the same time, according to this invention, the generator is equipped with a thrust sliding bearing, which has a journal in the form of a disc arranged on the rotor shaft, and a step-bearing in the form of a thrust sleeve, which covers the bearing shield at the side opposite to the basic shield, and is fixed with the help of bolts. The entire inner cavity of the generator is filled with water, and the generator with a hydraulic turbine arranged above it is submerged under the water level and is retained in this position with the help of floats, and is kept away from displacement by a retaining device.

EFFECT: reduced axial dimensions and material intensity of a generator with simultaneous increase of its operational reliability.
