Problems solved by technology

[0005] However, the above-mentioned hydraulic generator lacks the characteristics of constant frequency and constant pressure output. Moreover, although the forced circulation can be strengthened by the pressure circulation pump, there is still the problem of insufficient circulation power in actual use, mainly because the structure of the wire rod group is relatively curved. Many, the distance is long, and the cycle power is continuously consumed, which affects the cycle effect

Description

technical field [0001] The invention relates to the technical field of hydroelectric generators, and more specifically relates to a constant frequency and constant pressure hydroelectric generator system with the function of circulating evaporative cooling. Background technique [0002] A hydroelectric generator is a generator that uses a water turbine as the prime mover to convert water energy into electrical energy. When the water flows through the turbine, the water energy is converted into mechanical energy, and the rotating shaft of the turbine drives the rotor of the generator, which converts the mechanical energy into electrical energy and outputs it. It is the main power equipment for generating electrical energy in hydropower stations. [0003] There are mainly two traditional cooling methods for hydroelectric generators: air cooling and water cooling. The air cooling unit is an external cooling mode. It cools by blowing air outside the winding, mainly relying on th...
