摘要： In an air-cooled electrical machine having reverse cooling in a closed cooling circuit, a two-stage blade cascade for the optimum incident flow of cooling air to the rotor (4) and the rotor winding (29) is provided between a rotor cap plate (22) and a rotor shaft (28). The first blade cascade stage (30b) in the direction of flow is a deceleration cascade having pressure-generating properties, and the following blade cascade stage (30a) in the direction of flow is a deceleration cascade having deflecting properties.

摘要： In a shaft seal for hydrogen-cooled, turbo-generators, the operating requirements for a minimum gas-side leakage flow without secondary liquid circuit and cooling of the entire axial ring length are fulfilled either with choke elements (8) or with an inner transfer of sealing liquid from the gas side (G) to the air side (L) so that this shaft seal can function with a single sealing liquid circuit as a so-called single-circuit seal in parameter areas which are at present still the preserve of a multi-circuit seal.

摘要： Winding rods, built into the stator of an electrical machine, are no longer safe to operate after leakages in a water chamber. After this waterchamber has been removed, as is necessary anyway, a flexible, gas-proof hose is pulled upon the rod end, and the machine-side end of the hose is attached to the rod in a gas-proof manner. The other hose end is connected to a vacuum pump and, by evacuating the hose, the water that has penetrated into the rod insulation is removed by the same route as it penetrated into the insulation. The quality of this drying process is monitored by dielectric measurements.

摘要： A shaft sealing arrangement includes at least two seal rings radially enclosing a rotating shaft so as to define a clearance between the shaft and the at least two seal rings. A sealing oil supply channel is disposed between the at least two seal rings and a pump is configured for pumping a sealing oil through the sealing oil supply channel in a radial direction towards the shaft so that the sealing oil subsequently flows through the clearance in a first axial direction toward a first side of the sealing arrangement and in a second opposite axial direction toward a second side of the sealing arrangement. The sealing oil is collected on the first and second sides and at least partially reintroduced into the sealing oil supply channel. At least one seal ring includes a sealing oil return channel and at least a portion of the sealing oil flowing through the clearance exits the clearance in a radial direction through the sealing oil return channel and is at least partially collected and reintroduced into the sealing oil supply channel.

摘要： The invention relates to a rotor of an electric generator for generating electricity in power plants, comprising support elements (9) having spacers (10) between the conductors (6) in the area of the winding overhang (7). The spacers (10) are distributed over the surface of the support elements (9) as island-shaped structures so that the conductors can be cooled uniformly.
