A hydroelectric generator is a device that converts mechanical energy into electrical energy. The rotor is driven to rotate by the hydraulic turbine, and the coils in the stator move relative to the magnetic field of the rotor to generate induced electromotive force and current, thereby converting mechanical energy into electrical energy.
Features and advantages of permanent magnet hydroelectric generators:
1. The permanent magnet generator rotor adopts rare earth permanent magnet steel, no external excitation, no carbon brush, no sparks, no excitation winding, high motor rotor strength, no excitation control box, high generator efficiency, compact structure, and high reliability. The volume-to-weight ratio of the electric excitation generator with the same parameters is reduced by 30%, which reduces the construction cost.
2. The generator can achieve low-rated speed, eliminating the need for gearbox pulleys, etc. The hydraulic turbine directly drives the generator to improve system efficiency. The generator can output power frequency 50HZ at low speed. With the grid-connected inverter, the turbine can be released. In the dry season, the generator set runs at low speed and supplies power to the grid through the inverter; during the summer wet season, the turbine can eat more water, and the generator set runs at high speed, which can generate more electricity. The generator runs efficiently throughout the speed range.
3. Protection level: IP54, to prevent water, mud, and dust from entering the inside of the motor, and has a long service life. It is especially suitable for field needs. It is widely used in wind power, hydropower, ocean power, and other new energy power generation occasions.
4. The motor is air-cooled or water-cooled, and the temperature is low. The motor adopts imported oil-containing bearings, which are maintenance-free, high reliability, and has a long service life. The motor voltage, speed, power, and other parameters can be changed according to the needs, and the generator can be made into a horizontal or vertical type. It can use spline shaft extension, double shaft extension, front end stop output, etc., and can be treated with three preventions.
