Problems solved by technology

This configuration is limited to a certain type and size of turbine
[0005] Another drawback of prior art turbine generator arrangements is that they have relatively small bearings, which means increased wear and maintenance

Embodiment Construction

[0017] Figure 1 shows a tubular turbine plant with integrated turbine and generator, assembled from the following main components:

[0018] Centrally located generator unit 11;

[0019] a turbine unit 12 with blades 13 projecting radially from the generator unit 11;

[0020] Three tubular sections surrounding the turbine generator arrangement 11,12, an upstream tubular section 14 with end flanges 15,16, a central tubular section 17 with end flanges 18,19 and a downstream tubular section with end flanges 21,22. Part 20. The tubular sections are connected by bolting the flanges together longitudinally.

[0021] The upstream part of the turbine generator arrangement 11 , 12 is covered by a spherical dome 23 with six radial wings 24 supported on the inside of the tubular portion 14 .

[0022] Figures 2 and 3 show further details of the tubular turbine arrangement of Figure 1 . At least one wing 24 is hollow with an opening 25 through the wall of the upstream tubular portion 14...

Abstract

Electrical generator for use with a water turbine, said generator having a stator (47) with windings on magnetic cores, and a rotor (43) with a series of permanent magnets (46), with the rotor having connecting elements (42) for connection to a water turbine (41). The generator is surrounded by a housing (53) supplied with water from the water turbine. At least one of the bearings (49) of the generator is arranged to be supplied with water from the water turbine (41) for lubricating and cooling.

Description

technical field [0001] The invention relates to an electrical generator as described in the preamble of claim 1 for use with a water turbine. The invention also relates to a turbogenerator arrangement with a turbine combined with, for example, a generator. Background technique [0002] The turbine and the cooperating generator are usually built as separate units in separate locations and assembled with shaft couplings, gears and belt drives. This design requires more space and is not efficient from a manufacturing point of view. In addition, the generators require special cooling and each unit requires a complete journaling. A stand-alone design like this would require an enclosure, usually in the form of a shell, which would add to the cost of the small workshop. [0003] Turbines with a vertical axis are known, where the generator is arranged directly above the turbine, but this arrangement is limited to a certain type of turbine. [0004] Tubular turbines are also kno...
