The Main Structure of Generator Set

What is the main structure of the generator? Let's make a brief analysis. It is usually composed of stator, rotor, end cover and bearing. The stator is composed of stator core, wire wrapped winding, bracket and other frame members that fix these parts. The rotor is composed of rotor core (or magnetic pole, magnetic choke) winding, protection ring, central ring, slip ring, fan, shaft and other components.

The stator and rotor of the generator are connected by the bearing and end cover assembly, so that the rotor rotates in the stator, and the action of cutting the magnetic line of force generates the induced potential, which is induced by the wiring terminal and generates current after the circuit.

What are the main categories of generators? Let's make a brief analysis. Generators are classified as follows: DC generators and generators; Alternator minutes: synchronous generator and asynchronous generator (rarely used). Alternators can also be divided into single-phase generators and three-phase motors. There are many kinds of generators. In principle, it is divided into synchronous generator, single-phase generator and three-phase motor. It can be divided into steam turbine generator, diesel generator, gasoline generator, etc. In terms of energy, it is divided into thermal power generator and hydraulic generator.

What is the invention history of generator? Now let's have a brief introduction.

In 1832, Pique, France, invented a manual DC generator, which changes the magnetic flux by rotating the permanent magnet, thus generating an induction electromotive force on the coil and outputting it with DC voltage.

In 1866, German Siemens invented the encouraging DC generator.

In 1870, Gram, Belgium, manufactured the toroidal armature and invented the toroidal armature generator. This generator uses hydraulic power to turn the rotor of the generator. After repeated improvement, the output power of 3.2 kW was obtained in 1875.

In 1882, Gordon produced 447 kilowatts, 3 meters high and 22 tons of giant motors.

In 1896, Tesla's two-phase alternator began to work in Nyala Power Plant. 3750 kilowatts and 5000 volts of AC power were sent to Buffalo, 40 kilometers away.

What is the working principle of the generator? Let's make a brief analysis.

Diesel generator: the diesel engine starts the generator and converts the energy of diesel into electric energy. In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high-pressure fog diesel fuel injected by the nozzle. Under the pressure of the rising piston, the volume decreases and the temperature rises rapidly, reaching the ignition point of the diesel fuel. The diesel fuel is ignited, the mixed gas burns violently, the volume expands rapidly, and the piston pushes downward is called "work".
