LIQUID-FILLED ELECTRICAL MACHINE Russian patent published in 1997 - IPC

FIELD: electrical engineering. SUBSTANCE: the seal and the members in the form of shields form at least one space, which communicates with the electrical machine interior and environment. The shields have two spaced each and are installed at the ends of the stator body. The spaces in the shields communicate with each other through openings in the lower half of the given electrical machine, with the shaft surface - through an additional opening in the place of arrangement of the seal inside the machine, and with the environment-through an opening, in the machine upper part. The density of the liquid making up the environment exceeds the density of the liquid in the machine interior, but it is lower than the density of the liquid in the communicating spaces of the shields. A rib is installed in the boundary of the mentioned liquids. EFFECT: enhanced reliability. 3 dwg
