Rotor lifting of 400MW evaporative cooling large hydro-generator
In 1999, the 400MW evaporative cooling hydro-generator technology of Lijiaxia Power Station with independent intellectual property rights in China was put into commercial operation. The temperature rise of the motor was low, the temperature distribution was even, the vibration of the unit was small, and it was in the best operation state. . The application of this technology has greatly promoted the process of developing, designing and manufacturing the highest level of hydro-generators in China, improving the economics and safety of large-scale motor operation in China and the operation level of the power industry, and obtained industrial and industry experts. The recognition of China's power industry and motor manufacturing industry is of great significance. The research on the electrical insulation, heat and mass transfer characteristics of the new non-polluting cooling medium, the cooling principle of the components in the motor and the rotating state The development of engineering structures, theoretical and engineering research is in an international leading position.
