摘要:
Ein Turbogenerator (10) mit Mehrkammerkühlung, umfasst einen um eine Achse drehbar gelagerten Rotor und einen den Rotor konzentrisch umgebenden Stator (12), wobei der Stator (12) mittels Befestigungsvorrichtungen (18) auf einem Grundrahmen (14) befestigt und von mehreren, in axialer Richtung hintereinander angeordneten und voneinander beabstandeten, nach aussen geschlossenen Kaltluftkammern (15) für die gezielte Zufuhr von Kaltluft zum Stator (12) umschlossen ist. Bei einem solchen Turbogenerator wird eine flexible Ausgestaltung dadurch erreicht, dass die Kaltluftkammern (15) einen integralen Bestandteil des Grundrahmens (14) bilden.
摘要:
The method for impregnating with a resin (9, 10) an insulating material (3, 5) applied to a conductor (2) comprises supplying the conductor (2) with an intermittent current (12) during impregnation for it to generate a variable magnetic field. The conductor (2) comprises a plurality of transposed strands (4), and/or it is immersed in an external magnetic field, and/or it faces a ferromagnetic element (15).

摘要:
A coupling structure comprising coupling parts and aligners to connect the coupling parts. The aligner comprises a first circular element (1) with a first eccentric hole (6) and is contained in a hole (5) of a first coupling part (2). The structure gives flexibility to assemble the coupling parts and thus reduces the machining and assembling difficulty of the coupling parts.
摘要:
The electric generator (1) comprises a casing (2) that envelops a stator (3) and a rotor (4). The casing (2) has an aperture (5) through which the generator casing inside (7) is inspectable during generator operation. The method comprises inspecting during generator operation, through the aperture (5) of the casing (2), the casing inside (7).
摘要:
The device (10) for connecting together end winding parts (1) of stator bars (2) of an electric generator comprises a first and a second element (11, 12) having sloped facing surfaces (13) defining two trapezoidal seats each housing a trapezoidal cursor (14), and one or two screws (15), axially fixed and rotatably movable with respect to the first and second element (11, 12) and having a threaded portion inserted in a threaded through hole (17) of the cursor (14).
摘要:
The invention refers to a cooling system for the bushings (12) of an electric generator (1) that comprises a casing (2) housing a stator (3) and a rotor (4) connected to a rotor shaft (5) activating at least a fan (6) defining at least a high pressure zone (9) and a low pressure zone (8). The generator (1) has a plurality of phases electrically connected to hollow phase rings (11) that are electrically connected to bushings (12) supported by the casing (2) and having cooling circuits (22) to let a cooling medium (17) pass through them to cool them. The outlets (24) of the bushing cooling circuits (22) are housed in the high pressure zone (9) and are connected to inlets (32) of the hollow phase rings (11). The invention also refers to a method for cooling the bushings of an electric generator.
