HYDRAULIC-TURBINE GENERATOR Russian patent published in 2000 - IPC

FIELD: hydroelectric power engineering. SUBSTANCE: generator has rotor 1, hub 2 with spiders 3, armature 4, oil bath 6, brake disk 7, brake blocks 8, and hydraulic cylinder 9. Horizontal diaphragm 10 mounts U-shaped split casing 11. Annular trench 12 accommodates set of vacuum cleaners 13 uniformly arranged over circumference and connected through pipelines 14 to space formed by inclined wall of casing 11, armature 7, and horizontal diaphragm 10. Air is intensively evacuated together with products of wear of brake blocks preventing escape of wear products to environment and their settling down on pieces of equipment and stator. EFFECT: improved environmental friendliness, reduced labor consumption for cleaning stator and equipment, improved repairability and economic efficiency of generator. 1 dwg
