The hydraulic generator is mainly composed of a turbine and a generator.
The wheel and the generator are generally connected coaxially.
The difference in water level is used to drive the turbine and generator to produce electricity.
In other words, the potential energy of the water is converted into the mechanical energy of the water wheel to drive the generator and obtain electricity.
The principle of a hydroelectric generator (water turbine) is that when water circulates through the turbine, the energy of the water is converted into mechanical energy. The rotating shaft of the turbine drives the generator rotor, which converts mechanical energy into electrical energy and produces it.
The world's first hydroelectric plant was built in France in 1878. America's first hydroelectric plant was built in Wisconsin, United States, in 1882, using a current generator.ant continuous. After 1889, three-phase alternators began to be used. Since then, the capacity of a single machine has increased rapidly. In 1890, it was only 15,000 kW. By 1955, it could produce 105,000 kW generators. Before 1949, the capacity of a single unit of Chinese-made hydraulic generators did not exceed 200 kW. After 1949, the automobile industry developed vigorously. In 1958, it was able to produce a single 72,500 kW unit. In 1972, a double unit of 300,000 kW. -An internal water cooling water generator has been produced. The world's leading large-capacity hydroelectric generators are the 718,000 kVA stator water-cooled semi-umbrella hydroelectric generator of the Grand Coulee Hydroelectric Power Station, the 737 kVA stator water-cooled semi-umbrella hydroelectric generator 000 kVA Itaipu Hydroelectric Power Station and the 700,000 kVA water stator hydroelectric generator.-Guli Hydropower Station cooled semi-umbrella hydroelectric generator, kVA air-cooled umbrella hydrogenerator and 800,000kW Xiangjiaba hydrogenerator, etc.
