<p>The aim of the invention is to obtain a tubular turbine synchronous generator of cost-effective design and improved reliability. A tubular turbine synchronous generator has a stator (1) and a rotor (2) arranged in a tubular turbine housing (3). The tubular turbine housing (3) is sealed on the side facing the oncoming driving water (4) by the dome (5) of the tubular turbine. The generator is cooled by an intermediate circuit (6). This cooling efect is exploited to cool the rectifier elements (7). The rectifier elements are disposed with their respective cooling bodies in the dome (5) of the tubular turbine, around which the driving water (4) flows, i.e., directly on the intermediate circuit (6) of the generator cooling system. The cooling bodies for the rectifier elements (7) are thereby indirectly cooled by the driving water (4). The invention makes it possible for the first time to produce a tubular turbine synchronous generator which has no fans and therefore no rotating parts for the excitation. In the calculation of the profitability, costs for purchase of the fans as well as those for losses and maintenance can be neglected. In addition, there are fewer switch cabinets that require maintenance.</p> |
