FLUID-FILLED ELECTRICAL MACHINE Russian patent published in 1998 - IPC

FIELD: electrical and electromechanical engineering. SUBSTANCE: fluid-filled electrical machine vertically mounted in fluid-filled tube has case, wound stator, and rotor; novelty is that leakage-proof chambers also filled with fluid are mounted on butt ends of case. Each chamber accommodates diametrically opposite rods and piston held tight against stop by means of spring; sectional area of piston is larger than total area of rods. EFFECT: improved reliability due to preventing damage to insulation by vibration impacts of running machine. 2 dwg
