Embodiment Construction

[0031] figure 1 is a perspective side view of a preferred embodiment of the turbine generator of the present invention, and the cooling air chamber integrated in the bottom frame. The shown turbine generator 10 has no rotor axis (see 11 Image 6 ) rotating rotor without rotor bearings (see 23, 24 image 3 ) and the shell. The turbine generator 10 has a rigid rectangular bottom frame 14 in the length direction of the rotor axis, on which a plurality of box-shaped cooling air chambers 15 are sequentially arranged axially. Cooling air chamber 15 surrounds hollow cylinder or polygon body stator 12 (see figure 2 with Image 6 ), which surrounds its concentric rotor (not shown in the figure). A plurality of mutually spaced cooling air chambers 15 are connected to each other with a plurality of axially running pipes 19 (also see Image 6 ). However, it is also conceivable that the cooling air chamber 15 can be connected to a groove integrated in the base frame 14 . Such as ...

Abstract

Turbogenerator (10) comprises a rotor rotating and bearing along one axial line and a stator (12) concentrically enclosing the rotator, wherein the stator is attached to a base frame (14) using a fixing device (18) and enclosed by cold air chambers divided along a horizontal central plane into respective separate parts and closed to the outside, thus the cool air is guided into the stator (12). The flexibility structure of the turbogenerator is an integral part of the base frame, forming a cold air chamber.

Description

technical field [0001] The invention relates to the technical field of a turbo generator. The invention relates to a turbine generator according to the preamble of claim 1 . Background technique [0002] To date, there have been various arrangements of the cooling air chamber and hot air chamber arrangement of multi-chamber cooling turbogenerators. [0003] In European Patent Publication EP-A1-0840426, a multi-chamber cooled turbine generator is disclosed such as: see the figure 1 ), the cooling gas chamber and the hot gas chamber are arranged alternately and directly installed in the casing of the generator or machine, and the stator is completely enclosed. [0004] German Patent Publication DE-A1-19843529 discloses a turbine generator with multiple cooling chambers. The cooling air chambers formed by partitions are first directly fixed on the iron core of the stator, and the entire device of the stator and the cooling air chambers is placed on the bottom. frame and hold...
