Basic principle: In a hydraulic turbine, water flows radially through the water guiding mechanism through the guiding effect of the volute, converting the kinetic energy of the liquid into static pressure energy, then converts the static pressure energy. in kinetic energy of the rotor through the blades.
The runner is coupled to the generator rotor via the main shaft, driving the rotor to rotate and cutting off the generator stator magnetic coil. It uses the principle of electromagnetic induction to generate high voltage electricity in the generator coil. , then increases the voltage across the transformer for transmission. The cabling exports energy to the network and water flows axially out of the channel.
Large and medium-sized hydraulic turbines generally use metal scrolls, the main function of which is to guide the flow of fluid and convert cine energytick of the liquid into static pressure energy. The tilt angle of the movable guide vanes in the water guiding mechanism is adjustable, and its main function is to adjust the flow rate.
Hydraulic generator refers to a generator that uses a hydraulic turbine as the prime mover to convert water energy into electrical energy. As water flows 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. It is the main electrical equipment for producing electrical energy in hydroelectric power stations.
Types of generators:
(1) Wind turbine
The wind turbine relies on wind energy to turn the generator and generate current. ; this type of generator does not consume additional energy and is a pollution-free generatortion.
(2) Hydroelectric generator
The hydro generator uses the drop of water flow to generate electricity and drives the generator to produce electricity. It is also a device that uses green natural resources to produce. electricity. It is also called a water wheel.
(3) Gas Generator
A fuel generator relies on the combustion of diesel or gasoline to generate the energy needed to drive the generator. Using a small fuel generator can play an emergency role. In the event of a power outage, the fuel generator can be started to generate electricity to maintain normal operation.
